One of the problemsfacing most Farming Systems Research (FSR) practitioners is the difficulty in
locating and accessing relevant FSR literature. The expansion of FSR projects and programs has
greatly increased the number of articles, reports, and monographs dealing with particular aspects
of FSR. However, few of these documents reach a larger FSR audience. FSR literature is difficult to
catalogue in traditional research libraries. The interdisciplinary nature of FSR work makes it difficult,
if not impossible, to publish the results in refereed professional research journals. Additionally,
much of the FSR literature can be described as "ephemeral" or "fugitive" and consists of trip
reports, sections of the annual reports from national programs, and unpublished manuscripts from
the many seminars and workshops held on FSR topics. Due to these characteristics, the FSR
literature remains largely unavailable, especially to field-level practitioners, who by the nature of
their work are stationed in relatively isolated areas. The unavailability of these materials can only
slow progress in establishing and developing national FSR programs.

As part of its mandate to support the growth and development of FSR, the Farming Systems
Support Project (FSSP) is working to increase the availability of FSR literature. The FSSP is a
cooperative agreement between the Science and Technology Bureau of the United States Agency
for International Development (A.I.D.) and the University of Florida. Through a subcontract
agreement, the Kansas State University (KSU) has been designated the lead institution for the
documentation efforts of the FSSP. KSU has developed, with support from its A.I.D. Strengthening
Grant, a comprehensive FSR Documentation Center which is housed within its central library
facility. Using this as a resource base, KSU manages the annual selection of one hundred key FSR
documents for theirannotation and publication in a current-awareness, non-cumulative, selective
bibliography. Annotation, publication, translation into French and Spanish, and distribution of the
bibliography is handled by the Document and Information Handling Facility sponsored by A.I.D.'s
Bureau for Program and Policy Coordination/Center for Development Information and Evaluation
(CDIE)/Development Information Division.

This is the first volume of the bibliography. Subsequent volumes will be published annually
throughout the life of the FSSP. CDIE will catalogue and store all items included in the bibliography
series and will be able to provide copies of all uncopyrighted works and, with permission from the
publisher, of copyrighted articles. CDIE documentation center and duplicating services will
continue after the life of FSSP, thus ensuring that the documents contained in the FSR
bibliographies will remain available.

The FSSP is continuing to collect "fugitive" items for future FSR annotated bibliographies.
Suggestions for additional documents to be added to the collection can be forwarded to:

Soybean seed quality and stand establishment; pro-
Sinclair, J.B.; Jackobs, J.A.
University of Illinois at Urbana-Champaign. College of
Agriculture. International Soybean Program
(Conference on Soybean Seed Quality and Stand Establish-
ment, Colombo, LK, 25-31 Jan 1981)
INTSOY series, no. 22, 1982, xiii, 206 p., En
Published by University of Illinois at Urbana-Champaign
Grant DAN-1406-G-00-1015-00

Soybean research has shown that both physical and
biological factors are responsible for reduced seed quality and
vigor, that stand establishment depends on seed quality, and
that seed quality is directly influenced by weather conditions
during seed maturation and harvest and by subsequent storage
conditions. Because knowledge of these facts remains largely
fragmented and is not being communicated to farmers, the In-
ternational Soybean Program (INTSOY) hosted an international
conference in Sri Lanka for research scientists and exten-
sionists to correlate current knowledge on soybean seed quali-
ty and stand establishment, discuss ways to communicate this
knowledge to farmers, and determine future research needs.
The conference proceedings presented in this volume in-
clude: (1) 19 invited papers and abstracts of 13 volunteered
papers on soybean seed maturation, genetic differences in
seeds, the effect of weather, harvesting and planting pro-
cedures, and the role of insects and pathogens; (2) 11 country
reports from various Asian nations; and (3) reports from three
working committees on soybean production, crop protection,
and storage and mechanization
In the plenary sessions, the speakers voiced a number of
proposals on what emerged as a major concern among the
delegates-the importance of seed quality in expanding soy-
bean production in tropical and semi-tropical areas. Pointed out
in particular was the complexity of soybean seed production in
the tropics and semi-tropics due to the high humidity and
temperature levels that prevail throughout the year. Other
themes sounded were the necessity for good seed to make
soybean an economical crop and the nutritional importance of
All information presented during the conference related to
seed production, technology, and storage and to seed certifica-
tion in tropical and semi-tropical developing countries. Such in-
formation is directly related not only to INTSOY goals, but to
complementary efforts of other international donors such as
the Food and Agriculture Organization's ongoing Regional
Field Food Crops project in North Africa and the Middle East.

Apr 1981, 220p. : En Consultant report no. 7
In 1981 the Caribbean Agricultural Research and Develop-
ment Institute (CARDI) conducted a survey in order to charac-
terize animal production on small farms in the Eastern Caribbe-
an as to resources, constraints, and productivity level, and to
identify high priority experimental interventions to improve
productivity. Results are herein presented. Seven country re-
ports (St. Kitts-Nevis, Antigua, Montserrat, Dominica, St. Lucia,
St. Vincent, Grenada) are followed by a general characteriza-
tion of animal production systems in the region, and by discus-
sions of economic considerations and of possible interventions
in such areas as animal nutrition and health, genetic improve-
ment, animal husbandry, policy and institutional interventions,
and farm management.
The authors conclude that insufficient policy-level attention
has been given to coordinated parallel development of animal
production and crop production. While pricing policies are the
major constraint on self-sufficient animal production, other
problems (e.g., inadequate processing and marketing facilities
and high-priced imported feed) must also be addressed. Ap-
pended are a list of specific interventions to improve animal
production on small farms and a 35-item bibliography (1975-

Multiple cropping and tropical farming
Beets, William C.
1982, xiv, 156p. : Bibliography p.146-152, En
* Westview Press, 5500 Central Ave., Boulder, CO 80301
Well-planned multiple cropping is one of the more feasible
ways of raising agricultural production in the tropics, according
to this review of the subject. After an introductory explanation
of tropical farming systems and multiple cropping, the author
lists the types of multiple cropping systems and gives a history
of the practice. Discussion is then given to: (1) economic and
social factors affecting tropical small farm productivity (levels of
technology and resources, farmer managerial ability and tradi-
tions, agricultural infrastructure, population pressure, farm size
and type, and demand and prices); (2) agro-technical features
of multiple cropping systems (crop and variety selection, plant
population and spatial arrangements, timing, fertilization, irriga-
tion, erosion, crop management, and mechanization); (3) plant
interrelationships and competition; and (4) agro-ecological,
biological, and plant physical aspects (climate, soil, light, water,
micro-climate, and pests and diseases). Techniques for evalu-
ating the productivity of different cropping systems are ana-
lyzed, as are the selection and design of suitable multiple
cropping systems in terms of both natural environment and
human management. A discussion of research issues, includ-
ing a survey of current multiple cropping systems research,
concludes the study. Included are 56 figures and a 135-item
bibliography (1887-1977) of international sources.

Integrated crop-livestock-fish farming

FFTC book series, no. 16, May 1980, 147p.: En
Waste recycling is a key feature of successful integrated
crop-livestock-fish farming in the Republic of China, Malaysia,
Thailand, and several other Asian countries. The 17 papers
included in this volume the proceedings of a 1979 conference
on integrated farming show the complexity of integrated
farming systems in Asia and point out the need to develop
systems that are location-and situation-specific.
The first four papers provide an overview of integrated
systems in general and of systems having, respectively, crops,
fish, or livestock as the major enterprise (prefeasibility studies
for these three types of systems are also presented). The
remaining papers describe specific integrated systems in
Taiwan, the Philippines, Korea, Malaysia, and Japan; included
are discussions of an inland fishery, of complex upland farming,
of an integrated rice mill and farm complex, and of the
utilization of hog wastes through anaerobic fermentation. Sev-
eral issues emerge as important: analysis of the nature and
availability of environmental and socioeconomic resources;
new management skills and technologies for specific locations;
development of a systematic cooperative marketing scheme
through farmers' associations; applied research; and training of

Design and management of survey research: a
guide for agricultural researchers
Bernsten, Richard H.
1979, ii, 80p. : En
The value of data collected in an agricultural survey de-
pends on following established survey research principles. This
booklet outlines these principles and offers practical sug-
gestions to accommodate a wide array of field problems.
Discussion is given to: conducting pre-survey research to
determine the survey's purpose; focusing the survey's specific
analytical, disciplinary, and data goals; defining the sampling
unit and choosing appropriate sampling methods; choosing
primary data collection strategies (individual, group, and village
interviews, farm recordkeeping); designing, coding, formatting,
and pre-testing the questionnaire or interview questions;
selecting, training, and supervising hired interviewers; gaining
cooperation from villages and farmers; and selecting a data-
analysis system. While one-third of the report is devoted to
detailed instructions on preparing survey data for computer
analysis by SPSS (Statistical Package for the Social Sciences)
programs, it also suggests simpler analysis methods tabularr
sheets and sorting strips).

(Integrated systems of food plant cultivation
as a means of providing an adequate diet)
Burgos, Carlos F.
Tropical Agriculture Research and Training Center
1978, iii, 37p. : Es
A farming systems research (FSR) program undertaken by
CATIE to upgrade small farm diets in Central America is
described. After briefly defining characteristics of an
agroecosystem, the report describes: CATIE's FSR methodolo-
gy; the relation between farming systems and human nutrition
(especially proteins and energy); some nutritional aspects of
Central American crops (including corn, beans, and rice); and
results of CATIE's surveys of cultivation systems and nutrition
in Costa Rica, Nicaragua, and Honduras. A final section out-
lines a strategy to obtain an adequate diet through crop
diversification and intensification; home gardening of crops
such as corn or rice which can supply the nutritional elements
lacking in the main crop is suggested. Increased livestock
production is suggested as an alternative strategy. The need to
integrate food technology specialists with agricultural research-
ers in the entire research process is stressed. Included are 3
figures, 10 tables, and a 45-item bibliography (1949-78).

The development and content of a new course, entitled
"Farming Systems Research (FSR) in Developing Countries,"
first offered at Cornell University during the Fall 1980 semester,
are herein described.
Section I of this report presents the program of a workshop,
held at Cornell during the summer of 1980, at which faculty and
students examined proposals as to course activities, materials,
organization, and teaching methods. Included in the discussion
are comments pertaining to the philosophy behind the FSR
approach, the nature of inter-and multidisciplinary research,
and procedures for conducting field research. Section II pro-
vides an outline of the course as given in 1980 and summarizes
participants' comments on FSR as a research methodology, as
well as on pedagogical issues and course content and mechan-
ics. Section III provides an updated description of the second
FSR course (Fall 1981), highlighting specific changes from the
original offering, and again including student comments. Read-
ing materials associated with the course are listed in an annex,
which includes 16 pages of references (1951-81) divided into
methodological readings, bibliographic material, and works on
farming systems, cropping systems, and other farm manage-
ment topics.

Systems research in the arid zones of Mali:
initial results

ILCA systems study, no. 5, Aug 1981, 251p. : En
* ILCA, P.O. Box 5689, Addis Ababa, Ethiopia
The two main livestock production systems in Central Mali's
arid zones are the agropastoral and pastoral systems, defined
respectively by the relative domination of agricultural or live-
stock production. This report summarizes 5 years of research
on two subsystems of these systems the rainfed millet
cropping agropastoral system, and the pastoralism associated
with floodplain grazing and farming.
After a short description of Mali's natural resources, the two
subsystems are described in detail. The section on the millet
subsystem covers: labor; 1980 crop yields; the village econo-
my; the production and nutrition of livestock (cattle, sheep, and
goats); and crop agronomy and improvement, with a focus on
cowpea agronomy and millet fertilization. The section on the
pastoral system covers rangeland feed resources, livestock
production and nutrition, and the problematic social-territorial
livestock management framework.
A final section on future research prospects concludes that
the improvements in livestock production systems that are
possible given the Sahel's delicate ecological balance, may,
although slight, be vital for the survival of these economically
important systems. Included are 67 figures, 84 tables, and a 7-
page bibliography (1960-81) citing works in French and English.

Farm management in peasant agriculture
Collinson, Michael
1983, xxvii, 454p. : Bibliography p.433-444, En
* Westview Press, 5500 Central Ave., Boulder, CO 80301
This book, based primarily on research in Tanzania and
elsewhere in East Africa, describes how farm management
economics can contribute to the development of traditional
African agriculture.
Part I reviews the organization of African peasant agriculture
at both the farm and sector levels and then introduces a cost-
effective, systems-level approach for the application of farm
management economics. The approach evaluates the potential
impact of extension program content on the goals, managerial
task, and resource productivity embodied in existing small-farm
systems. Parts II and III detail methods for implementing this
approach. Part II, on the investigation phase, covers: farm
classification as a prerequisite to investigation and the accura-
cy/cost compromise inherent in survey design; a method of
building representative farm models which includes control of
aggregation bias; detailed descriptions and comparisons of
data collection methods for key attributes; and conclusions for
survey organization and design, based on different data collec-
tion methods. Part III, on planning extension strategy and
content, shows how evaluation criteria important to farmers are
used in interpreting the results of modeling. Based on the
premise that small farmers change their existing systems
relatively slowly, the aim is to produce a series of extension
programs, compatible with farmers' goals, low cash incomes,
and low risk preferences, and with the pressures on their land
and labor resources. Included are 109 tables, 7 figures, and a
12-page bibliography (1928-70).

The experiences of the International Maize and Wheat
Improvement Center (CIMMYT) in efforts to institute farming
systems research (FSR) in national agricultural research serv-
ices in Eastern and Southern Africa over the period 1976-81
are reported.
The author first examines how CIMMYT introduced FSR into
Africa via demonstrations which provided research administra-
tors with quick and tangible results for evaluating FSR ap-
proaches. A description of FSR procedures focuses on CIM-
MYT's use of the informal survey (a reprint of which is includ-
ed), a pivotal and cost-effective technique for diagnosing the
farming system. Progress in institutionalizing FSR in national
agricultural research services in Kenya, Zambia, Tanzania, and

Zimbabwe is reviewed. Emphasis is placed on: lessons learned
in modifying a strongly compartmentalized research network in
Kenya and the difficulties junior economists faced in initiating
dialogue with senior technical scientists in Kenya; how the
Kenyan experience was used to help reorganize and strength-
en the agricultural research system in Zambia; and the integral
link between FSR and inservice and short-term training work-
A concluding section analyzes several issues FSR as a
link between local and national priorities, whether FSR should
or should not be prefocused on a single enterprise (such as
maize), whether developing countries have adequate research
manpower for FSR, and issues pertinent to the further promo-
tion of FSR.

A low-cost, farming systems approach developed by the
International Maize and Wheat Improvement Center (CIMMYT)
for understanding decisionmaking by small farmers is pre-
sented; the method is described as applied to Central Province,
Zambia. Basic elements of the CIMMYT approach grouping
farmers into homogeneous populations on the basis of their
existing farming systems and evaluating local social and eco-
nomic circumstances in order to bring to light farm manage-
ment problems are described. Details are then outlined for
conducting an exploratory survey, i.e., unstructured farmer
interviews, to gain a rapid understanding of farming systems
and farmer decisionmaking patterns, and for a subsequent
formal survey to verify this information, test hypotheses regard-
ing farm management strategies and production techniques, as
well as farmer attitudes toward changes in these areas, and
examine farmers who have already made such changes. Vital
to the entire process is the interaction between biological and
social scientists. Detailed suggestions for an exploratory sur-
vey, as tested in Zambia, are appended.

Results of a diagnostic study of the farming systems of
Tanzania's Ufipa Plateau, together with suggestions for an
experimental research program aimed at helping Ufipa farmers
improve management of their increasingly important maize
crop, are presented.
After describing labor and land use in the plateau's current
farming system, and its major crops, the report examines the
rapid changes both in the system and in the constraints to its
development which have occurred after 1973 as a result of
increasing ox production and the official villagization policy.
Stress is laid on the declining importance of labor-intensive

finger millet cultivation and the correlatively increasing impor-
tance of the November-January labor peak. Maize manage-
ment practices in Ufipa are then quantified, and analysis is
made of the way in which maize management decisions are
influenced by farmer priorities, resource limitations, and haz-
ards such as the uncertainty of rainfall and crop losses due to
insects. The report concludes by proposing an adaptive re-
search program that focuses on testing ways to ease the
November-January labor bottleneck, conducting fertility main-
tenance trials to prolong the use of cleared land, and improving
the reliability of maize storage.

gap between farmers' present yields and the highest potential
yield for their fields after predetermined production factors are
modified? (2) How much of the yield gap can be attributed to
each of the predetermined production factors? (3) What are the
differences in costs and returns? (4) How much of the yield gap
can be profitably recovered? and (5) If the inputs that are most
profitable differ from the actual inputs used by farmers, what
personal, social, institutional, or political factors keep farmers
from using the most profitable levels? The handbook discusses
the selection of study area experimental sites, and factors to be
tested (such as fertilizer, weed control, and insect control).
Sample survey questionnaires are presented and illustrative
analyses are performed on constraint data.

(1979), (14p.) : En
The majority of animal products consumed within the
world's tropical belt are produced on small farms, typically as
part of a naturally integrated system of crop/livestock produc-
tion. This report begins by outlining three stages for study of
crop/livestock production before application of a broad-scale
development package: analysis of existing crop/livestock pro-
duction and marketing operations (to explain efficiency
parameters of livestock, the rationale for input levels, and the
mix of livestock products); definition and quantification of
constraints limiting animal production; and on-farm testing of
combinations of livestock enterprises and cropping systems.
Components of the crop/livestock system are then considered.
Discussed in turn are: general measures of efficiency; the
multiple uses of livestock; herd structure variables; animal
inputs into the cropping system; a model of crop-animal
integration in the Caribbean; the construction of feed demand-
supply balances; animal feed requirements; classification and
nutritional value of feed sources; relationship of feeding to
animal genetic qualities; and means of intensifying forage.
Modeling and species considerations are discussed briefly.

AID/REDSO/WA-77-107; AID/AFR-G-1261
This paper provides research results of a study of the
Southern Fulani farming system in south-central Upper Volta.
Following the Sahelian drought of 1974, donor agency and
governmental policy in this area has stressed shifting livestock
production from northern to southern and central regions of the
country in order to lessen dependence on erratic rainfall
patterns. Hypotheses about Fulani society and economic rela-
tions which address this strategy are researched and tested by
the author. Areas examined include: (1) characteristics of the
research site; (2) availability and allocation of labor within an
average household; (3) monthly flow of crop and livestock
outputs from the average household; and (4) a summary profile
of the typical Fulani production unit. The primary conclusion
resulting from this research is that the real potential for
economic growth through integration of crop and livestock
enterprises lies in closer relations between the Fulani and
Mossi tribes. The objective of rural development policy should
be to promote specialization in crops and small stock by the
Mossi, and cattle and small stock by the Fulanis. Recom-
mended policy actions cover 4 major types of interventions: (1)
government actions to bolster the cattle-entrusting system; (2)
creating a rise in relative returns to herdsmen for maintaining
entrusted cattle; (3) actions to move surplus Fulani cattle
manure to uses in Mossi market gardening; and (4) improving
herder access to purchased food grains. A bibliography of
references is provided, along with tables of labor flow data, and
samples of questionnaires used in the study.

cropping systems, especially for sorghum, in the Pespire region
of southern Honduras and ways they can be improved to help
the country out of its bleak agricultural situation.
After a general introduction to Honduras and to the south-
ern region, the region of greatest sorghum production, variants
of Pespire's two main cropping systems slash and mulch, and
slash and burn (both of which use sorghum and maize, the
region's two main crops) are described, as is the cultivation of
secondary crops and of pasture. The report then indicates
major production constraints in Pespire and some possible
solutions; seed types used in the area are characterized.
The survey showed sorghum to be both a multipurpose and
- due to its drought tolerance an important risk-aversion crop.
Key production constraints were identified as bird predation,
storage losses (especially to C. granaria), locusts, fall army
worm, and the eating of seed before it germinates by ants and
termites. The survey also revealed that wide adoption of
pesticides by farmers augurs well for future technology diffu-
sion efforts.
Two appendices analyze, respectively, the use of sorghum
as a human food and changing land use patterns in Honduras
and Central America; the latter indicates that increased cattle
production is leading to wholesale destruction of forests and a
reduction in arable land. Included are 22 tables and a 42-item
bibliography (1959-82) of English and Spanish titles.

Economics of systems research
Dillon, John L.
Agricultural systems, v.1, 1976, p.5-22 : En
The systems approach to agriculture, according to this
paper, constitutes a new way of viewing the world one which
no longer sees the world in terms of analyzable and
mechanistically related parts, but as an interacting and purpos-
ive whole. As a corollary, there are important implications for
agricultural research and professional research training. In
particular, the systems approach has an important role to play
in the allocation of research resources because it recognizes
that agricultural research is an instrument for achieving higher-
level goals (i.e., is not only oriented toward production in-
creases) and it provides a framework both for bringing research
alternatives to attention and for their assessment. Use of the
systems approach will allow decisionmakers to choose from a
variety of alternative research projects, based on systems
analysis of their probable outcomes. Moreover, a goal-orient-
ed, systems approach to research management, which has

Methods of conducting farm management research geared
to the needs of small farmers in developing countries, particu-
larly those in Asia and the Far East, are presented in this
After an introductory chapter on the need for and ap-
proaches to farm management research on small farms, meth-
ods of data collection (e.g., farm and village surveys, farm
recording schemes, case studies, and experiments) and simple
data analysis (including tabular analysis, measures of whole
and partial-farm performance, and comparative analyses) are
presented. Succeeding chapters outline methods of planning
and analyzing whole-farm and partial-farm budgets and cover
such topics as activity budgets; farm resource use; farm
programming and systems simulation; farm development bud-
gets; and partial profit, gross margin, partial cash flow, paramet-
ric, and risk budgeting. Procedures for conducting input-output
budget analysis are described (covering estimating benefits
and costs, allowing for capital scarcity, marginal analysis of net
benefits, etc.), followed by an introduction to the use of
production function analysis in farm management research.
The final chapter employs decision theory to analyze risk-laden
decisionmaking by small farmers.

approach to the Ethiopian rangelands
development project (third livestock

Ethiopian Cooperative Rangelands Production System Study
Mar 1981, 73p. : En
Development projects must take into account not just
technological feasibilities and national-level aims, but also the
production system to be developed, and the desires of the
society involved. Provided in this paper is a proposal for linking
project implementation to systems research in the Ethiopian
Rangeland Development Project.
Following brief introductory sections in which the author
explains the philosophy underlying the systems research ap-
proach to development, the approach itself is outlined, using as
an example two Ethiopian pastoral societies the wild northern
Afar or Danakil and the Borana husbandmen of the South. The
situation geography and ecology, external pressures, devel-
opment options, leadership, and social units of each society is
described. Also included are (1) study models prepared for the
two societies outlining questions which need to be answered
on nutrition, decisionmaking, herd structure, relationships with
neighboring pastoralists and farmers, market offtake, water
resources, and technical inputs and (2) information on the level
(personnel, specific tasks) at which studies can be initiated. In
conclusion, the author suggests that the methods being pio-
neered in the Ethiopia project may lead the way for complete
reorientation of livestock development projects in Africa.

Evaluates project to develop recommendations for im-

Eastern Caribbean. Special evaluation covers the period
through 4/8/82 and is based on document review, site visits,
and interviews with project participants.
Although the project's ambitious objectives have not been
fulfilled and many of the expected results not obtained, a sound
infrastructure for farm-level applied research and extension
has emerged, as farming systems research (FSR) has been
readily embraced by farmers and has become the focal point of
participating countries' agricultural research programs. Joint
country/Caribbean Agricultural Research and Development
Institute (CARDI) teams have been established in 7 countries
and some 25 farmer cooperators selected on each of the
islands. CARDI/FSR staff have become aware of the complex
farming systems in the region, a number of production con-
straints have been discovered, on-farm adaptive problem-
solving research has been initiated, and some observation
trials conducted. Also, various workshops and seminars have
been conducted for research personnel.
Progress has been hampered by a number of implementa-
tion problems, however. The project has been spread too thin,
geographically, to be effective. Interterritorial communication
has been poor and true interdisciplinary interaction among core
CARDI personnel not achieved. Overemphasis on data collec-
tion and detailed analysis, coupled with a lack of flexibility, has
led to a slow cautious approach to field trials. In fact, the project
has collected too much data, too rapidly, about a subsample of
farmers which represents neither a homogenous group nor a
random sample. The project's ad hoc exploratory interventions
(7-15 per country) represent constraints identified through
informal observation, not during the data analysis process.
Thus, to date, project research has added little knowledge
about or had little impact on farming systems.
Included in this evaluation are analyses of crop and animal
production in the Eastern Caribbean and of CARDI's organiza-
tional and functional patterns. Detailed recommendations for
Phase II of the project address these and other issues.

The potential for improving multiple cropping systems de-
pends on the researcher's ability to combine genetic advance
with new agronomic techniques. Thus concludes this paper,
which was presented at a plant breeding symposium held at
Iowa State University in 1979.
Emphasis throughout is on intensive cropping systems that
combine two or more crops in the field at the same time.
Species choice and genetic selection are discussed first;
attention is given to the interactions of genotypes in different
cropping systems, and statistical alternatives for comparing
these interactions. Steps in the practical screening and testing
of new cultivars are then outlined: the decision to breed for
intercropping systems; phenotypic traits desirable for inter-
cropping (with respect to photoperiod, temperature sensitivity,
plant morphology, rooting systems, planting density, and early
seedling growth); insect and disease resistance; screening
techniques for breeding; and on-farm testing and technology

Problems and achievements resulting from the introduction
of farming systems research (FSR) into the national agricultural
research system in Honduras are examined in this study.
After providing a historical overview of agricultural research
in Honduras, the authors discuss the organizational framework
for FSR in the country, focusing primarily on the creation of a
Central Unit for FSR within the Honduran Ministry of Natural
Resource's National Program of Agricultural Research. Next,
implementation of the FSR program is addressed, with particu-
lar attention to: selection of regions, farmers, and specific
problems for on-farm and on-station trials; experiences in
implementing farm trials and farm recordkeeping systems;
research results and efforts to extend FSR to other regions;
and training of Honduran researchers. Key problems e.g., in
introducing FSR to agricultural research personnel, in commu-
nicating among the various entities involved, and in obtaining
sufficient resources are described.
It is concluded that while not all of the program's goals were
realized, a good deal was achieved in modifying research
philosophy and methodology. Recommendations for imple-
menting FSR in other countries are provided. Appended are a

French edition: PN-AAN-029
It is increasingly evident that public investment in farming
system research (FSR) over the last 20 years has been
focused on the needs of commercial farmers and professional
researchers rather than on the needs of developing country
small farmers.

Defining farming systems as human and environmental
totalities, the authors of this state-of-the-art study review the
literature on FSR, evaluate current FSR programs, and make
recommendations to make FSR more responsive to small
farmer needs. The political, social, technological, and human
components of a farm system are reviewed, and a framework
and general description are provided for "downstream" FSR.
Unlike "upstream" FSR, which takes place on an institutional
level and seeks to generate prototypes to solve deep-seated
production constraints, "downstream" FSR is directed at gen-
erating, in cooperation with farmers, immediate and site-
specific solutions to their needs. Current "upstream" and
"downstream" programs at the national (e.g., Columbia, Guate-
mala, and Senegal) and international levels (e.g., IRRI and
ICRISAT) are reviewed, as are several issues affecting the
programs' content and focus, including institutional mandates,
linkages among research and implementation agencies,
professional and practical credibility, efficiency and accounta-
bility of research, and constraints of and criteria for improving
FSR approaches. Next, the four stages of FSR methodology
are detailed: target area description and diagnosis; project or
experiment design; testing or implementation; and evaluation
and extension. Problems involved in institutional linkages and
in FSR training programs are also covered. General conclu-
sions and three concerns regarding FSR (conflicts of private
and public interests, gaining sufficient funding, and time to
prove FSR's worth) preface the following recommendations:
direct future FSR work toward cost/benefit analyses in different
ecological zones; develop methodologies to include livestock
and societal, environmental, and distributional impacts; and
establish more operational linkages between FSR activities
and the entire range of agricultural research, planning, and
program implementation.

Agricultural research can have no impact upon small far-
mers' cultivation practices unless it addrees farmers' real
problems and defines efficiency in, farmers' terms. Traditional
research and development efforts unilateral flows of initiative
and information directed by national planners, executed by
technicians through commodity programs, and imposed upon
farmers often result in production techniques that are rejected
by small farmers. This report describes the development of
Guatemala's Institute of Agricultural Science and Technology
(ICTA), which is dedicated to a decentralized research method-
ology designed to make research programs responsible for the
adoption of appropriate agricultural techniques by including the
contributions of farmers and social scientists. Under ICTA's
interdisciplinary research program, mainly developed by its
Socio-Economic Unit (SEU), natural and social scientists sur-

vey farmers to identify homogeneous groups and their produc-
tion constraints. The farmers then record their cultivation
practices, supplying data about annual crop labor/resource
investments. Experimentation with specific treatments, such as
agronomic practices or crop varieties, is based on farmer
information and the results of controlled tests at production
centers. Using the farmers' traditional techniques, an agrono-
mist and farmer test the selected treatments and then apply
them to larger areas at different sites. In the next phase, the
farmer tests the treatments alone; ICTA personnel visit to
record information and conduct evaluations. Problems arose in
the initial implementation of this approach, as technicians
deprecated farmer input and SEU's low-level regional pre-
sence was often erratic. The situation improved as technicians
began to realize the benefits of farmer participation and as SEU
sent adequate personnel into needed areas. The use of leader-
ship farmers to monitor recordkeeping and test sites also has
been helpful. An indication of the obstacles facing those
introducing such innovations is provided in the authors' histo-
ries of ICTA and SEU, including the latter's conflicts with
external and internal proponents of traditional methods and
relations with similar institutions.

The past (1969-80) achievements and future prospects of
the Multiple Cropping Program (MCP), a multidisciplinary re-
search project being conducted by Chiang Mai University in
Northern Thailand's Chiang Mai Valley, are assessed.
Initial chapters describe the Valley's structure (including
water supply, cropping intensity, population, infrastructure, and
villages); dynamics (seasons, cropping patterns, prices and
labor, long-term cropping changes, and crop stresses and
perturbations), and farmer decisionmaking processes (as af-
fected by national policy objectives and local needs and
constraints). Against this background, the performance and
constraints of the MCP systems introduced into the Valley by
the University, together with the productivity, stability, and
durability of these systems, are assessed. A detailed series of
key evaluative questions covering all major areas of the Valley
system is posed. Preliminary answers to these questions
provide a basis for a concluding outline of research priorities
and future directions. It is stressed that the program's compara-
tive advantage lies in its focus on the research questions raised
by the evaluation. The text is illustrated by 96 charts, tables,

Methodological issues facing social scientists in applied or
on-farm farming systems research (FSR) were discussed at a
4/80 workshop held at CIMMYT. Initial discussions of these
issues, according to this report on the workshop, focused on
the role of the social scientist in FSR and on the usefulness to
farmers, policymakers, and experiment stations of on-farm
FSR, as well as on the latter's cost-effectiveness. Discussion
on the farmer as research client covered the choice of farmer
target groups and the appropriate size of recommendation
domains; whether to focus on a predetermined commodity
rather than the whole farm system (the report recommends the
latter when it is technically feasible and there is little hope for
improvement in the farmer's main crop); and the general
preferability of individual technological components to large
technological packages. Discussion on the advantages and
disadvantages of various data sources and data collection
instruments are summarized, and the wisdom of following the
informal survey with a formal survey and of making observa-
tions in farmers' fields noted. The report's concluding sections
summarize discussions on procedural issues in designing,
testing, and evaluating new technologies including on-farm
testing, prescreening, farmer assessments, and analysis of
economic impacts and on integrating social scientists into

12 Aug 1982, 25p. : En
Agroecosystems are determined by both ecological and
socioeconomic factors. This paper analyzes how these two
types of factors influence farmer decisions in designing and
implementing (controlling) a farm management plan.
Several determinants of farmer decisions are enumerated:
the natural environment, which affects the agroecosystem
either directly (through the availability of energy and material
inputs) or indirectly (by triggering farmer decisions); agricultural
resources (land, labor, capital, management capability, and
farm inputs); the farm household (which mainly affects design
decisions); energy and material flows from other
agroecosystems; and the ongoing performance of the
agroecosystem itself. Specific hypotheses regarding determi-
nant-decision relationships are exemplified from experience in
Central America the relations between temperature and
cropping system selections (a design decision) and between
the onset of the rainy season and selection of the first crop in a
rotation system (a control decision). Concluding sections of the
paper discuss the implications of these issues for farming

The conceptualization of a farm system as a set of
subsystems with inputs, outputs, and between-system flows
can be a valuable tool in cropping systems research. Thus
concludes this article, which begins by describing data col-
lected from one farming household in Yojoa, Honduras. Begin-
ning in May 1976, Mr. Aureliano Alvarado, having been select-
ed as a representative farmer, was interviewed weekly over a
one-year period. Quantitative interview data were analyzed and
from them a qualitative model of a farm system, showing
socioeconomic and agro-eco subsystems, their inputs, out-
puts, and between-systems flows of money, materials, energy,
and information, was constructed. This model and the interview
data were then used as guidelines in developing methodologies
for further cropping systems research at Yojoa. The major
findings resulting from this research are described and sug-
gestions for refining the methodology provided.

While farming systems research (FSR) has made a major
contribution to agricultural extension, there is still a gap be-
tween the information needed for technology transfer and that
produced by most FSR projects. In this paper, the concept of
agroecosystem determinants is proposed as a framework
which can be used to identify the information needed to link
FSR with technology transfer.
The author begins by discussing the nature of
agroecosystems, and their relationships to farm systems and
socioeconomic systems. Farm system decisionmaking is ex-
amined next and it is shown that these decisions are based on
one or more of the following types of agroecosystem determi-
nants: the ecological and socioeconomic environment; agricul-
tural resources; the household; the performance of the existing
agroecosystem; and the flow of materials or energy among
agroecosystems. Identification of these decision determinants,
it is suggested, can be used by FSR workers to implement a
process which links technology generation to technology trans-

Vol. I, 1984

fer, by first identifying the type of farm system and of ecological
and socioeconomic environment where a new technology is
appropriate and then testing its applicability on other farms in
other areas. Technology that passes this final test is then
communicated to all farms in all areas where it is appropriate.

Tropical farming systems are interactions of varied but
complementary farm enterprises undertaken with limited re-
sources. This book analyzes ways in which such farming
systems can be used to further agricultural development.
Part one presents an overview of tropical small farms and
their production systems, with explicit attention to the stages
and goals of small farm development and indicators of farmer
well-being. The final chapter in this part the heart of the whole
book suggests a development approach for collaboration
among scientists, extensionists, and farmers to develop and
extend relevant technology to resource-limited farms.
Part two deals in greater depth with critical but often
overlooked factors limiting increased cropping intensity on
small farms and describes existing and/or appropriate methods
of addressing them. Treated in turn are: physical limitations
(water, soil fertility); economic determinants (labor, cash, man-
agement capability); resource requirements of multiple
cropping; animals in mixed-cropping systems; farmyard and
fencerow noncommercial enterprises; soil fertility; efficient re-
source use; and the need for mechanization. Finally, it is
stressed that farmers will only adopt systems that involve
minimum risk and maximum stability.

Agricultural administration, v.8, 1981, p.423-432 : En
The Sondeo is a multidisciplinary rapid survey technique
developed by the Guatemalan Institute of Agricultural Science
and Technology (ICTA) to provide the information needed to
orient the work of a technology generating team. A reconnais-
sance survey team of 10, equally split between
socioeconomists and technologists, assesses farmer con-
straints and technology needs as a basis for agricultural
research. Quantified information and questionnaires are not
required and the survey lasts only one week. The team
investigates farmer conditions in pairs made up of a social



scientist and a natural scientist. On each of four days the
pairing changes. Daily post-survey team discussions are re-
garded as essential. Each member of the team prepares a
report and these are finally amalgamated into one joint report.
Experience has shown that combined disciplines can, if well
managed, produce incisive and efficient diagnoses of rural
conditions and needs and educate the participants in mul-
tidisciplinary thinking. (Author abstract, modified)

The multidisciplinary research methodology of the Guate-

outlined herein, aims at developing the low-risk technologies
needed by traditional small farmers to increase the production
of basic grains. The methodology has four components. The
first, description and analysis, focuses on informal and formal
agro-economic surveys of targeted groups of farmers having
common cropping systems. Adaptive research, the second
component, consists of two phases an initial period of
experimentation aimed at improving traditional technology in
the short run, and a longer process of refining the improved
traditional technology. The third component consists of testing
and promoting the technology through two types of on-farm
trials farm experiments, financed by ICTA, and farmer tests,
financed by farmers themselves. The fourth component evalu-
ates long-range technology adoption through farm records,
technician reports, comparative trial records, and followup
surveys. A final section of the report describes use of the
methodology in various parts of Guatemala La Maquina on

In the project, which focuses on keeping crop records (as

needed for data gathering/analysis and training, data from daily
work sheets kept by farmers and from supplemental sheets
filled out by ICTA personnel are analyzed to provide detailed

Results of a 5-year project aimed at incorporating the social
sciences into the Guatemalan Institute of Agricultural Technol-

this consultant's report.
The report describes the development and use of a social
science methodology based on full-scale agro-economic
surveys preceded by preliminary questionnaires (sondeos)
administered to farmers aimed at helping ICTA researchers
focus their work on small farmer needs and problems; stress is
laid on the importance of field activities in La Barranca and
Tecpan. A related farm records project is briefly assessed. The
use of sondeos, the involvement of farmers in technology
development, and the conducting of research under conditions
relevant to farmers enabled the project to increase the speed
and efficiency with which agronomists developed appropriate

were integrated into many ICTA programs, their long-term role
within ICTA is unclear: failure to replace social scientists who

improved cropping practices. The Small Farmer Cropping Sys-
tems Project (SFCS) supported research by the Tropical Agri-
culture Research and Training Center (CATIE) in Costa Rica on
the traditional multicropping systems used by over 4 million
small farmers in Costa Rica, Nicaragua, Honduras, El Salvador,
and Guatemala. Although progress was slow in El Salvador and
Guatemala, the project succeeded in implementing on-farm
research and developing area-specific recommendations. The
major shortcoming of the 5-year project was that it concen-
trated on the research process itself rather than on verifying
and disseminating results. Farmer impact was thus limited to
the 75 small farmers on whose farms research was conducted.
Farmers in Nicaragua and Guatemala were active participants,
whereas those in Costa Rica and Honduras remained largely
ignorant of the project and disinterested in adopting alternative
systems. Test farm yields increased in every country but
Guatemala. CATIE's staff, training, and support capabilities
were greatly improved and most national agricultural institu-
tions involved were positively affected. The team concluded
that SFCS is a replicable model capable of significantly improv-
ing the lot of the small farmer. Recommendations for future
projects are: (1) disseminate research results; (2) stress an
interdisciplinary approach; (3) seek the active participation of
farmers; (4) improve SFCS methodology by upgrading farm
selection criteria, clarifying the relationship between on-farm
and central station experiments, and increasing attention to the
non-agronomic aspects of small farm systems; (5) promote
maximum interagency collaboration; and (6) shorten the time
lag between research, verification, and dissemination. Appen-
dices on evaluation methodology, project impact on CATIE,
and CATIE's production data are included, as are reports on
Nicaragua, Guatemala, Honduras, and Costa Rica.

Measures to strengthen the Honduran National Program for
Agricultural Research (PNIA) are suggested, based on a review
of agriculture's role in the Honduran economy and an assess-
ment of the existing PNIA program.
The authors found that PNIA was characterized by: (1) a
program largely restricted to station-based varietal testing and
agronomy trials; (2) a network of research stations badly
needing improvement; (3) a serious shortage in trained man-
power; (4) productive but limited linkages with other foreign and
domestic research institutions; and (5) lack of administrative
control over the research budget. Suggestions for strengthen-
ing agricultural research focus on: reorganization of PNIA into
three levels headquarters, central unit, and regional units, the
latter comprised of both farming systems teams and station-
based teams; inclusion of an extensionist on each farming
systems team; full PNIA control over its research budget; a
substantial increase in technical personnel as well as inservice
and advanced degree training requirements; and increased and
strengthened relations with other research and development
institutions. Implementation and funding of these changes are
discussed. Appendices include budgetary and staffing data and
a report on animal production and research.

The current (1979) Honduran National Development Plan
places top priority on the traditional small and medium farmers
who together produce at least 70% of the country's grain.
Experience has shown that research in traditional, as distinct
from modern, commercial agriculture, must take into account
ecological, economic, and technological conditions, as well as
limits and possibilities and hence is preferably conducted on-
farm rather than at experimental stations. This manual provides
a methodological guide for conducting on-farm trials. After an
introductory section on problem identification, treatment is
given in turn to choice of location, arranging the experiment,
site characterization, and data needs at each stage of the
farming process. Included are two appendices, one on evaluat-
ing weeds, the other on evaluating insects and leaf disease
affecting beans, corn, and sorghum.

Nearly every aspect of farming in the semi-arid tropics was
examined at the workshop, and it was felt that only through the
dissemination of information and an integrated systems ap-
proach can farming problems be remedied. Toward that end,
this report includes the papers presented at the workshop and
the discussions following each major group of topics. The first
group, Committee I, covered those subjects related to resource
assessment and utilization of research on farming systems in
the semi-arid tropics. Major attention was given to land, soil,
water, climate, and manpower resources for improving produc-
tion under the rainfed conditions in this seasonally dry area.
Committee II examined the crops and cropping systems re-
search needs for the semi-arid tropics, and Committee III
discussed the socioeconomic problems related to farming
systems research in this area. Finally, Committee IV explored
the question of research at cooperating centers and transfer of
technology. The group evaluated various ways for the interna-
tional institutes to play a productive role in the generation of
location-specific technology and its transfer to the different
agro-climatic and soil regions in the semi-arid tropics.

New technologies cannot be disseminated in developing
countries without an understanding of local socioeconomic
conditions. Such is the view adopted by the International Crops
Research Institute for the Semi-Arid Tropics (ICRISAT) in
sponsoring the International Workshop on Socioeconomic
Constraints to Development of Semi-Arid Tropical Agriculture,
held February 19-23,1979 in Hyderabad, India, the proceedings
of which are presented in this report. The Workshop's primary
aim was to consider ways and means of overcoming the
various socioeconomic constraints to agricultural development
in the semi-arid tropics (SAT) and emphasis was focused on
the role new technologies and/or policies could play in alleviat-
ing development constraints in SAT. The subject matter ses-
sions addressed the analysis of existing farming systems and
practices, socioeconomics of prospective technologies, field
assessment of prospective technologies, issues in foodgrain
marketing, the nature and significance of risk, rural labor
markets, and the economics of improved animal-drawn imple-
ments and mechanization. Among the important observations,
it was noted that larger farmers were earlier and more frequent
adopters of new technology and that lack of capital is a major
constraint to adoption. Research indicates that the sum total of
current agricultural policies reduces farm income so that the
incentive for increasing cereal production is probably nil. One
common recommendation emerging from all sessions was the
need to improve the methodological and empirical bases on
which policy judgements are made. There is a particular need
for data on the importance of risk and uncertainty in determin-
ing farmer behavior in SAT regions as well as on labor
bottlenecks and on the degree to which new technology
constrains labor and affects wage rates. It was also recom-
mended that greater emphasis be placed on understanding the
nature of consumer preferences and that policy initiatives in
foodgrain marketing consider the economic policies of SAT
countries as well as the political situation of both donor and
host government agencies. Appended are texts of papers
presented in French and lists of country papers and of work-
shop participants and observers.

Apdo. Postal 6-641, Londres 40, Mexico 6, DF, Mexico
A key reason preventing farmers in developing countries
from adopting fully the technologies recommended to them by
researchers and extensionists is the inappropriateness of the
technologies themselves. This manual was prepared to present
procedures and guidelines to assist agricultural researchers in
formulating technologies truly appropriate to farmer needs and
is divided into three parts. Part I presents an overview of a
research program aimed at developing appropriate technolo-
gies. Included are descriptions of on-farm and experimental
station research the key research procedures involved and
the government policy context in which research must occur. It
is emphasized that successful research must proceed from
knowledge of the farmer's circumstances, that is, the factors,
both natural (e.g., climate and soils) and socioeconomic (e.g.,
farmers' goals, markets, national policy) that affect farmers'
decisions on crop technologies. Part II describes procedures
for obtaining information on these circumstances, with stress
laid on the need to make the process a true collaboration
between researchers and farmers. Specific procedures de-
tailed are: gathering and analyzing pertinent background data
from government and research reports; conducting an explora-
tory survey, that is, informal interviews with farmers and other
knowledgeable individuals; and conducting a formal survey or
questionnaire. Individual chapters discuss questionnaire devel-
opment, sampling methods, and practical ways to make the
survey truly collaborative. In Part III, methods are discussed for
gleaning from survey results the information pertinent to plan-
ning crop research. In particular, the authors present guidelines
for prescreening a few two or three at most are recom-
mended "best-bet" technologies for research. A final chapter
exemplifies use of these guidelines in two on-farm programs
and one on-station program. The authors note that those who
think researchers should only go to farmers with finished
technologies for demonstration will find this manual less useful
than those who support on-farm research. Graphs, charts, and
a 25-item glossary of terms are included. Short bibliographies
are appended to each chapter.

yields, but also concerns itself with the number of crops grown
each year, with the goal of increasing food production. The
papers are organized into these categories: framework for
cropping systems research and development for the Asian rice
farmer; physical aspects of cropping pattern design; economics
of cropping systems; testing of cropping patterns; component
technology including weed science, insect-pest management,
and varietal requirements; and cropping systems approach to
adaptive research and to production programs.

Limiting factor economic evaluation of
cropping systems
Johnston, T.D.
Tropical Agriculture Research and Training Center. Program
of Annual Cultivation
1978, viii, 31p. : En, Es
The cropping systems most likely to improve farm family
income are those which identify that resource which most limits
per ha yields. Since different types of small farmers need
different kinds of farming and cropping systems, such informa-
tion requires a thorough study of the resources, cropping
systems, and farming systems of particular groups of farmers
and of the social, cultural, agroclimatic, or marketing con-
straints which dictate the use or avoidance of particular
cropping systems. While researchers cannot, of course, devel-
op a system for each farmer, farmer groups can be identified by
differences in goals, farming systems, resource mixes, agrocli-
matic characteristics, etc. Awareness of these differences will
enable researchers to design improved systems which make
more efficient use of each group's most limiting resource and
which thus stand a much better chance of being adopted.
In this study, the methodology for conducting such a limited
factor analysis of a small farm is described and exemplified
from a study in Costa Rica. Charts measuring total inputs and
prices against outputs for each of five cropping systems
demonstrate which system produces the highest income for a
particular limited resource. (Author abstract, modified)

Polyculture cropping systems; review and
Kass, D.C.
Cornell University
Cornell international agriculture bulletin, no.32, 1978, 72p.:
An analysis of the literature indicates that polyculture, or
growing two or more useful plants simultaneously in the same
area, is generally beneficial. The choice of crops and other
environmental variables will determine to a large extent wheth-

er the practice is advantageous in specific situations. In terms
of withdrawal of nutrients from the soil, economic return,
improvement of the nitrogen status of the soil-plant system
when one of the crops is a legume, and greater stability of
yields over time, the benefits of polyculture are clear. With
regard to ease of harvest and other mechanized operations,
polyculture offers some problems but recent research aimed at
reducing these difficulties has been surprisingly successful.
Certain species and combinations of species appear to perform
more successfully in polyculture than do others. Associations
of cotton, groundnuts, and maize-legume combinations are
commonly used and it is the price relationships of these
combinations, rather than the cropping systems themselves,
which appear to be the determining factors. The effects of
climatic change on polyculture have been well documented,
primarily with respect to wet and dry seasons in the tropics
rather than year to year variability in the same cropping season.
The fact that nutritional requirements and physiology of varie-
ties within a single species may vary more than those of
different species has been described in the literature of polycul-
ture. Suggestions for further research are summarized.

Farm mechanization problems that occur when developing
countries import agricultural machinery are analyzed in this
-paper, which focuses on problems in Nigeria.
Following background information on the role of farm equip-
ment in general and on different sources of power (manual,
animal, and tractor power), the author identifies and discusses
four problems associated with importation of agricultural ma-
chinery: focus on larger units which often are not economical;
lack of appreciation of local cropping systems and of negative
effects on women (who must increase their labor in order to
harvest and process increased crop outputs); poor perform-
ance of imported equipment; and failure to encourage local
development and manufacture of equipment. Findings from
Nigerian field trials concerning operational constraints on trac-
tors and the performance of crop protection and harvesting
equipment are presented. The author concludes that farming
systems must be balanced in the technologies they employ;
exporters of agricultural machinery should invest in research to
modify their product to suit developing country situations. A 27-
item bibliography (1962-82) is appended.

Small farm management in Kyela Plain, Tanzania, is the
subject of this study, which was based on interviews with
farmers and village leaders and conducted to provide a knowl-
edge base for farming systems research in the area.
Farming circumstances in Kyela natural, economic, and
institutional are described first, followed by a discussion of
farmers' objectives (primarily subsistence), priorities (staple
foods, such as rice, maize, and bananas), and available re-
sources (land, labor, and capital). Findings in these areas are
then related to farm management practices cropping patterns
and the crop calendar, soil fertility maintenance, and means of
dealing with specific resource limitations such as seasonal
labor shortages. The next section identifies hazards faced by
farmers (floods, delayed rains, pests and disease) and their
strategies for dealing with them, e.g., use of cassava and sweet
potatoes as insurance crops, multiple plantings of major crops,
and early planting. Finally, suggestions are presented for
resolving the labor bottleneck, introducing new cash crops, and
improving rice management. Appended is a 10-item bibliogra-

A 1976 project to demonstrate the use of an interdisciplinary
farming systems approach in planning adaptive agricultural
research in Kenya's Siaya District was the initial effort of the
International Maize and Wheat Improvement Center's (CIM-
MYT) Regional Programme in Economics for Eastern Africa.
Results of that planning project are herein presented.
After providing background information on the CIMMYT
program and on procedures to be employed in interdisciplinary
research planning, the report examines farmer circumstances
in the Siaya District, taking into account the area's climatic and
soil conditions, off-farm economic conditions, and land, labor,
capital, and farm management factors. Next, the objectives and
priorities of Siaya farmers (mainly, reliable food supplies) and
the farming system and its development are analyzed, and the
importance of deciding on the future of livestock operations is
noted. A 5-year maize research program, based on an analysis
of key farming systems components (varieties, use of pur-
chased inputs, method of and time of planting, thinning and
weeding), is outlined for Siaya areas receiving less than 1,500
mm annual rainfall. Comments on possible improvements in

Screening crop innovations in a whole-farm
Labadan, E.; Bantilan, C.; et al.
International Rice Research Institute
13 Dec 1980, 26p. + appendices: En
Although researchers frequently use the farmer's field as
the unit of analysis when evaluating crop innovations, since
methodologies for this are readily available, farmers normally
judge new cropping patterns on the basis of their total farm-
household operation. This report presents an example of
whole-farm analysis of alternatives for new cropping systems
at a site in Cagayan Valley in the Philippines.
The new cropping patterns are evaluated for bio-technical
feasibility, profitability, and compatibility with the farming sys-
tem and with the community's socioeconomic infrastructure.
The research site and a 3-component farm planning linear
programming model are described. The components include an
objective function (farmers' goals), a set of alternative activities
(e.g., crop and livestock production), and a set of constraints
(e.g., land, labor, and power availability). Three classes of
innovations are considered: alternative cropping patterns/tech-
nology, institutional credit, and irrigation.
It is concluded that while whole-farm analysis via linear
programming offers considerable analytical power, its field use
is limited by its reliance on computers; simpler analysis meth-
ods must be sought for use at cropping systems sites. In the
example cited, four typical weather occurrences (2 floods, a
drought, and a typhoon) affected the analysis. Future planning
models should account for environmental realities; a sequen-
tially oriented decision model is recommended. A 27-item
bibliography (1961-80) is appended.

To examine changes in land use and farm production as
population pressures increase, this study uses data from three
Eastern Nigerian villages with markedly differing population
The first section provides a historical review of land use
systems in Eastern Nigeria and discusses emerging problems
related to population growth. The second, treating farm and
household as a unit, analyzes how root crop/oil palm farming
systems have changed in relation to changes in land resources.
Subsections cover: the resource base; the organization of land
use; soil fertility; crop production; yield relationships; the live-
stock economy; the labor economy; and economic returns and
the use of cash income. The analysis shows that farmers react
to declining soil fertility and yields by concentrating production
on small compounds around the house which receive mulch
and manure from household refuse, outlying fields, and land
under fallow, and thus have a much higher yield than do
extensively used fields. Another finding is that off-farm income
increases with population growth. The third and final section
assesses a number of proposed strategies for increasing
productivity, including: combining upland tree cropping with
arable crops; producing wet rice in valley bottoms; and
developing a multistoried cropping system near houses. De-
tailed data and a case study are provided in 13 appendices and
a 19-page bibliography (1910-76) is included.

The author concludes that since irrigated rice farming
requires extensive capital investment, support to rainfed
cropping is indicated when the target is a rapid increase in
production. Included are 9 appendices providing additional
detail and a 17-page bibliography (1935-77), citing works in

xiii, 236p. : Bibliography, p.219-236, En
Although rice may be grown in West Africa as either an
upland rainfed crop or a lowland irrigated crop, development
efforts have emphasized irrigated rice production. This study,
focusing on the Ivory Coast, investigates the conditions under
which rainfed cultivation in permanent arable farming or ley
systems may be more profitable for farmers and feasible on a
macroeconomic level.
First, using data from other West African countries, the
economics of rainfed rice cultivation at the farm level is
analyzed for various cropping methods and different levels of
farm mechanization. Two case studies from the Ivory Coast are
then presented, examining, respectively, the profitability of
traditional and semi-mechanized upland rice production under
favorable climatic conditions in the West Ivory Coast and under
unfavorable conditions in the Central part of the country.
Following this, rainfed and irrigated rice production are com-
pared from a macroeconomic point of view.

Methodology for determining insect control
Litsinger, J.A.; Lumaban, M.D.; et al.
International Rice Research Institute
IRRI research paper series, no.46, 1980, 31p. : En
A cropping systems approach has recently emerged as an
effective means of improving insect control a task which,
because of its complexity, high demand on resources, and
location-specific nature, has impeded past efforts to produce
on-farm yields comparable to those obtained at research
stations. This report explains the role of cropping systems
research in insect pest control and outlines a methodology for
determining insect control recommendations.
Cropping systems research entails specifying a given insect
pest control technology by taking into account the cropping
patterns of individual farmers, the geographical and temporal
distribution of pests, environmental parameters (e.g., rainfall,
soil type, landform), cultural practices (e.g., planting, irrigation,
and insecticide application methods), farmers' capabilities

Vol. 1, 1984



(e.g., resources, beliefs, and customs), and a crop's inherent
yield potential. A four-part methodology for using cropping
systems data, developed in accordance with the requirements
of the Asian Cropping Systems Network of research sites, is
presented. The initial stage, description, entails gathering base-
line economic and biological data on pests known to farmers,
the level of pest control needed, the current status of insect
control, and the kinds and levels of technology farmers are
willing to adopt. Next, several tentative insect control technolo-
gy packages compatible with farmers' resources and capabili-
ties are designed. These packages consist of specific insect
pest control recommendations i.e., lists of insects and the
insecticides effective against them, resistant varieties, and
cultural control methods pertaining to the entire spectrum of
pest problems for each crop within the target area. These
alternative packages are then tested for several years at each
site. Finally, the costs and returns of the alternative packages
are evaluated. The above method, in the authors' opinion, will
allow the development of optimal insect control recommenda-
tions within 2-3 years, is highly objective, is not costly, and can
be carried out by researchers with minimal experience. A 21-
item bibliography (1976-79) is appended.

The level and speed of farmer adoption of technologies
generated in an on-farm research program undertaken by
Panama's Institute of Agricultural Research (IDIAP) in the
country's Caisan area are used in this report as a means of
assessing the cost-efficiency of the research methodologies
employed in the project.
After a lengthy description of the evaluation methodology,
results are discussed with regard to the adoption of technologi-
cal alternatives; the annual flow of net benefits due to the new
technology (including yield increases and net benefits per unit
of land); and the annual flow of research costs. The benefit-
cost ratio and the social rate of return of the research method-
ologies are then calculated.
Results, which confirm the cost-efficiency of IDIAP's on-
farm methodologies as compared to traditional research sta-
tion methods, show that the lowest rates of return generated by
the on-farm research methodology were 118% and 155%
(depending on the pricing scenario adopted), a figure increas-
ing to between 194% and 255% in the most likely case of a
new flow of social benefits lasting until 1990.

Interaction between cultivation and livestock
production in semi-arid Africa
McCown, R.L.; Haaland, G.; De Haan, C.
Ecological studies, v.34, 1979, p.297-332 : En

Low crop yields and a high risk of crop failure have
traditionally led farmers in semiarid Africa to rely on domestic
grazing animals to supplement their food supply. This paper
identifies different types of linkages between cultivation and
livestock production and considers the conditions under which
each linkage is expected to occur.
Two types of linkages are distinguished those that obtain
when agricultural and livestock production are separated (eco-
logical, competitive, and exchange linkages) and those that
obtain when the two are integrated (investment, food, manure,
draft, and fodder linkages). Patterns of cropping/livestock
production linkages are examined in eight summer rainfall,
semiarid African zones (Western Senegal, Bambara and Gour-
ma of Mali, Mossi in Upper Volta, Hausaland in Niger and
Nigeria, Bokoro of Mali, Western Darfur in Chad and Sudan,
Harar in Ethiopia). Finally, evolutionary trends are discussed to
consider what linkages are likely to emerge under different

Guatemala: development of the Institute of
Agricultural Science and Technology (ICTA)
and its impact on agricultural research and
farm productivity

In 1975 A.I.D. initiated a project to increase the production
and nutritive quality of basic crops in Guatemala and to develop
the capability of the Institute for Agricultural Science and
Technology (ICTA) to generate and promote the use of im-
proved small farm technology. This report describes the proj-
ect's setting and activities, outlines its impact, and summarizes
its lessons.
Under the ICTA system, new farm-tested seed varieties and
cultural practices acceptable to small farmers were developed
for maize, beans, and sorghum and led to increased yields and
development of a thriving private seed industry. In addition,
ICTA staff increased both quantitatively and qualitatively (al-
though rigid government salary schedules have led to a high
attrition rate among the 10 Guatemalans who received ad-
vanced degrees, threatening ICTA's future progress); benefited
from expatriate help in its research work and organizational
growth; and received dramatic increases in financial support
from the government. ICTA has come to represent a new and
innovative model for agricultural research and is now working
to share its approach with DIGESA, the Ministry of Agriculture's
extension service.
Project experience taught: the benefit of an unconventional
approach to generating acceptable small farmer technologies;
the importance of sustained USAID/G involvement and of
investing simultaneously in human, institutional, and technolog-
ical resources; A.I.D.'s potential for developing agricultural
institutions, its comparative advantage in institution-building
projects, and the need in such projects to provide for an
institution's support after the project ceases; the productivity of
ICTA's linkages to international and U.S. agricultural research
centers; the importance of coordinating technology and sociol-

financial incentives to retain ICTA's advanced degree scien-
tists, special feedback information systems to test technology
results, and flexibility in project implementation.

proach to technology development and farmer acceptance of

partially irrigated areas and the need for additional power for
planting, weeding, and harvesting. The need for a more or-
ganized and concentrated production program is also in-
dicated. In Lampung, good rainfall and distribution make year
round crop production possible despite low inherent soil fertili-
ty, drainage problems, and low pH; limited sources of power
and of markets are currently the main production constraints.

Training institutions and government agencies need to
become more aware of the integral and essential role played by
animals in small farm systems. So concluded participants at a
10/78 international conference hosted by the Rockefeller
Foundation, working papers from which are herein presented.
An initial paper provides a conceptual framework of the
different types of farming systems in the developing world (by
animal species, dominant crop, main feed resources) as an aid
to understanding various crop-livestock relationships. More
specific information is given in a paper describing levels of
crop-livestock integration within selected systems in Asia,
Latin America, and Africa. Each system is discussed in terms of
the region's physical features, crops and cropping systems,
and the current and possible expanded role of livestock. A case
study of a small farm in the western highlands of Guatemala
leads to a review of the kinds of problems which have inhibited
integrated development of crop and livestock technology: lack
of a holistic view; the dominance of Western models of farm
systems; emphasis on large-scale farms and productivity; and
professional biases (e.g., single commodity stress). Summary
conclusions and recommendations conclude the report.

Goat husbandry practices were surveyed in two villages with
different agricultural settings in the Way Abung II transmigration
project in the Northern Lampung Province of Sumatra, In-
donesia, in order to determine the potential for goat production
intensification programs in these areas. Results of the survey
are presented.
After briefly recounting the history of the area, the report
describes the agricultural setting; husbandry of goats, cattle,
and chickens; labor use by farm families; crop, livestock, and
input markets; and formal and informal credit sources.
The survey revealed that although Way Abung farmers
clearly prefer to raise cattle, profitability and especially higher
fertility and lower mortality portend a considerable potential for
increasing goat production. Constraints to realizing this poten-
tial poverty and lack of cash resources should be removed
in the next several years as a result of clove, fruit tree, and
rubber plantation production. Currently, however, vaccinating
poultry against Newcastle Disease and increasing the use of
cattle in the slack agricultural season are more appropriate
than are goat projects in the livestock sector. Goat projects
relating to male and female breeding stock and production
credit might be initiated. If so, they should include research
aimed at increasing high quality fodder on small farms.

For subsistence farmers, physical and biological factors are
most important in determining the production system (i.e.,
cropping pattern) to be used. This report describes the produc-
tion systems best suited to the various climatic conditions in
Central America.
Precipitation is seen as the most important factor in deter-
mining crop combinations in the region. Cropping patterns are
outlined first for the humid tropics: for regions without a dry
season, those with a short drier period, and those with an
identifiable dry season. Similarly, cropping patterns are outlined
for "humid dry" regions, those with greater fluctuations in
rainfall. In general, small farmers can grow corn, rice, and
cassava in the most humid regions, corn and beans under
intermediate rainfall, and corn and sorghum in the driest
regions. For each region, the sequence of farmers' activities is
outlined by calendar dates.

Three integrated farming systems research projects being
conducted by the Institute for Tropical Resources (CATIE) to
relieve the production constraints facing Central American
small farmers are described.
The report first outlines the goals, strategy, and methodolo-
gy of CATIE's small farmers' cropping systems research proj-
ect, as well as the design, testing, and evaluation of technologi-
cal alternatives. Project experiments include testing water and
soil conservation practices in El Salvador and Nicaragua and
using velvet bean as a cover crop in lowland areas.
Similar information is given for the other two projects one
aimed at using crop byproducts to develop an integrated small
farm crop-cattle (milk and beef) production system, and one
designed to counteract deforestation by developing alternative
production systems that combine agricultural and tree crops,
forest plants, and animals. Experiments for the first of these
projects include using maize-bean combinations and sweet
potatoes as cattle food sources; for the second, simultaneous
planting of trees with annual crops and interplanting maize and
common beans between rows of fast-growing tree species. A
brief note on integrating and extrapolating from research re-
sults concludes the report.

Showing the utility of on-farm research while presenting a
model for the administration and organization of such research
within a larger program, this report describes the evolution of a
new research entity, the Production on Investigation Program
(PIP), within Ecuador's National Institute for Agricultural Re-
search (INIAP).
In 1976 INIAP added to experiment station research and
regional trials on large farms a third research level, centered
directly at the farm level, in order to develop and verify
technologies appropriate for the mass of small farmers produc-
ing basic foods, such as corn, which had declining or static
yields. The essential elements of the research process which
emerged, described in detail in this paper, were: (1) delineation
of recommendation domains; (2) use of exploratory surveys to
identify key farming improvements needed (early maturing
varieties, fertilizing, and weed and insect control); (3) on-farm
variety, multiple-factor, fertilizer-level, and verification trials;
and (4) adjustment of subsequent on-farm and on-station
experimentation in terms of findings. PIP, established in 1979
as a means of institutionalizing the on-farm program, is charac-
terized by personnel especially trained in on-farm research
living on-site and by strong coordination with other INIAP
programs and with extensionists.

Small farmers in St. Lucia employ a heterogeneity of
cropping patterns and technologies including multiple
cropping and polyculture, in which four to six crops are planted
in vertical and/or horizontal combinations. Using data from an
island-wide sample of 31 farmers, this report examines St
Lucia's small farming systems with respect to land tenure,
farmer classification, and climate.
First, the island's system of land tenure is analyzed, and it is
shown how tenural arrangements family land, annual leasing,
freeholding, or sharecropping are maximally manipulated by
the farming household. It is noted that the various land tenure
arrangements have evolved due to limited alternatives and
scarce resources (e.g., farm labor, capital, inputs, and farm
management) and that fragmentation of land is not as severe a
problem as in other developing countries. Next, St Lucia's
system of farm agriculture and differences in level of farming by
category of farmer (e.g., commercial, semi-commercial) are
assessed. Crop differences by climatic zone are described;
while various cropping patterns are identified, it is noted that
each farmer in the sample seems to have developed his/her
own unique system. A concluding section identifies key con-
straints on increased food production.

Farming systems approach: relevancy for the

Farming systems research (FSR) is a "bottom-up" or farm-
level approach to the development of small farmer technolo-
gies. This paper defines the basic characteristics of FSR, gives
examples of successful FSR projects, and discusses problems
in implementing FSR.
Conventional agricultural technology development tries to
modify technical farming elements but ignores human factors.
FSR, on the other hand, recognizes and focuses on the
interrelationships between technical and human elements in a
farming system. Its primary aim is to increase productivity in a
way that is acceptable to the farming family. FSR gives the
small farmer, often for the first time, a voice in tailoring research

priorities. Farmers and multidisciplinary teams work together to
design, modify, and improve farming systems in a local area.
Although agricultural scientists for years have disdained
mixed cropping, an FSR project in northern Nigeria showed that
mixed cropping was an efficient strategy for farmers facing land
or labor constraints or uncertain weather. In northern Nigeria, a
FSR cotton project succeeded after farmers rejected a univer-
sity-designed cotton planting technology package because its
labor demands were incompatible with their farming systems.
An FSR project in Southeast Asia led to a dramatic increase in
cropping intensity in only 4 years while in Guatemala an FSR-
revised planting system increased farmers' income by 33%.
However, FSR is still in a developmental stage and faces
numerous problems, including the short supply of researchers
capable of understanding and working with small farmers in
developing countries; the lack of a standard methodology; and
the time demands and expense of its area-specific approach.
To overcome these problems, FSR should: expand its systems
approach to include marketing and off-farm enterprises;
strengthen links to extension agencies in order to reduce time
lags between recommendation and adoption of solutions; and
develop more widely applicable technology packages. Also, if a
working environment more favorable to FSR is to be created,
agricultural institutions and scientists will have to take a more
holistic approach and be more willing to interact with farmers
and extension workers. A list of 28 references (1972-79) is

As an indirect recipient of Ford Foundation grant funds in
1964 and of subsequent funding from the Ahmadu Bello
University, the Institute of Agricultural Research and Special
Services has undertaken a four-phase social science research
program to study the economics, profitability, improvement,
and implementation of small farming in Hausaland. Reporting
on only a small portion of this total program, this paper presents
a comparative analysis of the economics of traditional small-
farm agriculture in Sokoto, Zaria, and Bauchi, three areas in
Hausaland; assesses the profitability and relevance of im-
proved technological packages for cotton, sorghum, and
maize; and discusses the implications of the results for re-
search workers and policymakers in Hausaland and in the
Sahelian countries with a similar ecological base. Following a
very brief discussion of the farming system and of Hausaland
proper, the methodology for the selection of villages and farm
families for study is outlined. A description of the method of
data collection is also included in this section. So that study
results are presented in an orderly manner, the next three
sections concern traditional farming in the Hausa region, com-
parative analysis of traditional farming in the Sokoto, Zaria, and
Bauchi areas, and an analysis of improved technology pack-
ages in Daudawa village in the Zaria area. Traditional farming in
Hausa is discussed in terms of land, labor and labor concentra-

tions, capital, cash production costs, land and labor relation-
ships, cropping systems, and income. The following factors are
applied to the comparison of traditional farming in the three
study areas: effect of population density on farming; effect of
climate on farming; self-sufficiency and incomes among areas;
influence of cattle ownership; the changing family structure;
and influence of access to urban areas. The analysis of
improved technology packages is described by their compati-
bility with technical elements (land types, water), with endoge-
nous factors (return per unit of land, and return per unit of
labor), and with exogenous factors (market accessibility, credit,
fertilizer distribution). Finally, a section containing a summary
and implications for consideration by the policymaker includes
the concluding statement, which is also the premise of this
paper: that sound development of farming systems must build
upon, rather than destroy, the farmer's traditional techniques. A

improving agricultural production and the welfare of farming
families in the semiarid tropical region of West Africa. The
authors draw extensively on comprehensive studies they and
their associates conducted over an 11-year period in northern
Nigeria. Their discussion of these studies, which focused on
production, consumption, and marketing systems and included
the testing of improved technology packages, is supplemented
by results of research conducted in other parts of semiarid
West Africa. Emphasizing the importance of a proper under-
standing of the technical and human environment in which
farming families operate, they describe the essential charac-

A short course was developed in 1971 at the University of
Sydney, Australia, on the basic biological and physical princi-
ples of tropical farming systems. This textbook was developed
from the course to serve as an introduction to annual cropping
systems, particularly in Africa and Asia.
A farming system is first described, with specific reference
to resource patterns and uses, farming system typology, and
tropical climates and soils. Next, background information on
hydrology, energy, biogeochemistry, and socioeconomics in
tropical farming systems is provided. These same four factors
are then discussed with reference to the following specific
types of annual cropping: shifting cultivation, semi-intensive
and intensive rainfed cultivation, and irrigated cultivation. Mixed
systems of annual and perennial crops are viewed from the
same aspects.
The final two chapters describe, respectively, the role of
livestock in annual cropping systems and the elements of
tropical farming systems research: its meaning, objectives, and
components. Included are evaluations of established farming
systems, of environments, and of the transfer of new technolo-
gy. References follow each chapter.

Plant breeding literature has largely been concerned with
analyzing the products of plant breeding and with redirecting
research from simple yield objectives to broader considerations
such as crop stability and disease and pest resistance, while for
the most part neglecting to examine the use of nutritional

Vol a 1984




criteria to determine research priorities. This paper, using Sri
Lanka's plant breeding program as an example, explores
nutritional criteria for plant breeding, and, in particular, technical
problems that have frustrated breeders.
The Sri Lanka program shows that strategies for nutritional
improvement encompass far more than just concerns as to the
protein profiles of individual crop species and that issues such
as pricing policies, subsidies, and distribution mechanisms
should inform and direct nutritional programs. Moreover, the
fact that nutritionists have clearly stated that crop protein
values are not below safe levels for human intake should lead
plant breeders to refocus their attention toward carbohydrates
and toward the neglected area of improving the oil content of
food species. Unfortunately, there is little evidence that this is
taking place. Appended is a 23-item bibliography (1966-80).

From agronomic data to farmer
recommendations: an economics training
Perrin, R.K.; Winkelmann, Donald L.; et al.
International Maize and Wheat Improvement Center
Information bulletin, no.27, 1976, 52p. : En
The quality of recommendations that agronomists make to
farmers depends upon how carefully the agronomist has con-
sidered all of the factors relevant to the farmers' situation and
goals. Some of those factors may not be evident to the
agronomist. This manual shows agronomists how to develop
recommendations suited to the farmer's desire to increase his
average income, avoid risks, and, if possible, avoid investing in
additional capital equipment. A good farm recommendation can
be defined as a choice the farmer himself would make if he had
all of the agronomic information available to the agronomist.
Successful farm recommendations must be based on agro-
nomic data that fit the farmer's agronomic conditions or the
farmer will not obtain the predicted results. Because it is
impossible to conduct experiments on each farm and then
make recommendations tailored to each farm, the agronomist
must define a target group of farmers, conduct experiments
under conditions representative of their farms, and make
recommendations applicable to the entire group. This manual
assumes that farmers think in terms of net benefits as they
make decisions. Illustrative examples of this decision process
are discussed. The two main problems in evaluating agronomic
alternatives in terms of their net benefits are (1) estimating the
relative weights the farmers place on various kinds of goods,
and (2) estimating the effect of uncertainty on farmers' deci-
sions about net benefits. The process of deriving recommenda-
tions is discussed in detail.

Although integrated agriculture aquaculture (IAA) farming
has been practiced in Asia for centuries and offers efficient
resource utilization, reduces risk by diversifying crops, and
provides additional food and income, reliable quantitative pro-
duction and management guidelines have yet to be produced
and disseminated for use as a basis for development programs.
This report on the proceedings of the Fourth International
Center for Living Aquatic Resources Management Conference
(ICLARM 4) addresses this need. The conference was held 6 -
9 August 1979 in Manila, Philippines and was co sponsored
by ICLARM and the Southeast Asian Regional Center for
Graduate Study and Research in Agriculture. The conference's
goals were to: (1) provide an overview of current IAA farming
practices in selected Asian countries; (2) increase awareness
of IAA's ability to raise farm income; (3) review available
experience and technology; (4) discuss IAA's socioeconomic
aspects in order to identify research and development priori-
ties; and (5) encourage governments and international donors
to initiate IAA research and development projects. The report
consists of 24 papers, 10 of which review broad strategies,
techniques, and problems associated with IAA, such as
aquaculture in rice fields and irrigation systems; the role of
pesticides and health as constraining factors; and the use of
animal wastes in pond management. The other 13 papers were
presented as case studies on current IAA practices in Hong
Kong, Hungary, India, Indonesia, Japan, Malaysia, Nepal, the
Philippines, Taiwan, and Thailand. A final paper highlights the
needs for research on both IAA farming systems in general and
on the major factors affecting IAA performance energy,
materials, space, time, and information. Many of the papers are
detailed studies, supported by charts, data, pictures, diagrams,
and maps; and most are referenced with bibliographies on
sources of information on IAA. A list of the authors and of the

Farming systems research in North Kordofan, Sudan: report,
no.2, Nov 1982, xi, 151p. : En
Its goal to identify socioeconomic constraints impeding
agricultural production and marketing in the el-Obeid area of
Kordofan, Sudan by analyzing relationships between subsist-
ence (sorghum and millet) and cash (primarily groundnuts and
sesame) crops, this is the second of two farming systems
research reports written during the course of field investigation
in 15 villages.
Part I, on household economy and agricultural production,
presents detailed data on crops, land tenure and land use,
cultivation practices, and methods to reduce risk and labor
inputs, using findings from a preliminary survey of 40 farm
households in 3 villages. Part II, based on data on sellers,
buyers, and marketing channels collected at four marketing
centers of varying size and character, describes major aspects
of crop and livestock marketing. Part III is an analysis of the
main constraints to agriculture in the area (environmental;
access to seeds, water, and labor; credit and pricing; technical
knowledge; and transport and storage), how farmers presently
deal with these constraints, and what strategies they could
implement in the future. Eleven appendices provide additional
data (on, e.g., harvesting procedures, food preparation, con-
sumption patterns) not easily reviewed in the main body of the
report plus a copy of the survey questionnaire.

If properly conducted, informal agricultural surveys can
provide valuable data on local farming ecology and practices.
Presented here is a manual on conducting informal surveys of
farmers in developing countries.
Instructions are provided for (1) pre-fieldwork activities,
such as a literature review and the use of aerial photos and
maps to delineate the geographical area to be studied; (2)
interviewing farmers (approach, warm-up, dialogue, departure,
and recording of information); (3) informally organizing data by
type of farmer and cropping system; (4) studying agroecologi-
cal zones through the use of field plotting and transects; (5)
initial quantification of data; and (6) writing a summary report of
findings. Appended are results of an informal survey conducted

Drawn from the experience of Honduras' Central Agricultur-
al Research Unit, this inservice training manual has six sec-
tions. The introduction reviews changes in the agricultural
research program (1977-80) and the new structure of the
program. A section on inservice training objectives explains
that, in general, new technicians in the research program are to
receive preparation for close contact with the farmer and for
study of integrated systems, and specifically to: analyze and
identify agricultural production problems; set priorities; conduct
farm trials; communicate with farmers; analyze and transmit
technical information; apply basic knowledge; and work as a
team. Next, a section on methodology and organization out-
lines the training, which continues for 9 months in Comayagua,
with 75% of time spent in practice, 25% on theory. Practical
activities (section 4) are divided into the following: diagnosis;
farm trials; farm plots; farm assessment; precipitation measure-
ment; and field days. Theoretical activities (section 5) include
11 short courses, 10 lectures, 8 workshops, 10 seminars, and

A course consisting of lectures on the characteristics of
tropical farming systems for undergraduate and graduate stu-
dents at Gottingen and Stuttgart-Hohenheim Universities was
the basis for this book, intended to familiarize the agricultural
development worker with the various types of farming he/she
will encounter, and with management problems arising in
particular farming systems.
Tropical agriculture is discussed from an agroeconomic
perspective, with emphasis on farm management aspects and
particularly on the interactions between technical and econom-
ic aspects of farming. An initial chapter covers general charac-
teristics of tropical farming. Succeeding chapters, organized as
to type and intensity of land use, discuss the following types of
cultivation systems: shifting cultivation; semi-permanent; regu-
lated ley farming (when grass is allowed to grow for grazing on
land that has carried crops); permanent cultivation on rainfed
land; arable irrigation farming; perennial crops; and grazing
(total nomadism, semi-nomadism, and ranching). In each chap-

organization of growers; and present and future marketing
prospects. A final section reviews the program's effects on the
Kigezi District as a whole, on the cooperative societies, and on
farm returns. The program's positive results, it is concluded,
show that producer interest and dependence on a crop can
overcome disadvantageous factors; that the African small-

Farming systems research and development (FSR&D)
views the farm as a system and focuses on how interdependent
components under the farm household's control interact with
physical, biological, and socioeconomic factors outside the
farmer's control. This monograph contains nine readings pre-
sented before a 1979 workshop by some of the leading
practitioners in FSR&D.
The first paper categorizes farming systems according to
their stage of development and resource use, while the second
conceptualizes FSR&D and raises several methodological is-
sues. Successive papers outline and discuss the FSR&D
experience and approaches of the International Maize and
Wheat Improvement Center, the International Rice Research
Institute, the Agricultural Science and Technology Institute of
Guatemala, and the International Crops Research Institute for
the Semi-Arid Tropics. Two papers discuss FSR&D as applied
to a small farm in Honduras and cropping systems research in
Indonesia, respectively. Stressed are the importance of on-
farm research, interdisciplinary teamwork, the search for practi-
cal solutions to farmers' problems, and better use of available
data. A subject index is included.

A Farming Systems Research and Extension (FSR&E)
symposium was held in 11/82 at Kansas State University to
examine issues in the application of FSR to development
projects. Twenty papers from the symposium are herein pre-
sented, all of which focus on issues raised by experience,
rather than theory.
Following an overview of the current state of FSR&E and its
potential for the future, indepth case studies of four field
experiences (IRRI/Indonesia, CIMMYT/Panama, ICAR-
DA/Syria, and CATIE/Central America) are presented. The
next five papers analyze specific problem areas (links to
farmers and to other research programs/units, cost-effective-
ness, transplanting U.S. methodologies, and conceptual errors
in evaluation). The final ten papers, presented at small group
meetings, address further FSR&E implementation and evalua-
tion issues, e.g., in staffing, integrating team participants,
organizing a delivery system, incorporating nutritional consider-
ations, transferring station work to farm conditions, impact
evaluation, and in determining the role of energy in farming
systems. These papers make clear the necessity of systemati-
cally examining not only the farming system and its internal
resources, but the containing system as well. Two precon-

Hidden harvest: systems approach to

It has been estimated that up to one-third of the food
produced in developing countries is lost due to inefficient
postharvest operations. After delineating various types of
postharvest loss (losses in nutritional and economic value, in
weight, and in quality and acceptability), the author of this
report recommends a systems approach to postharvest losses
and identifies the following primary components of the posthar-
vest system: harvesting and threshing; drying and storage;
processing; and utilization by the consumer. The interrelated-
ness of specific problems that may arise within the system is
then demonstrated. Next, the Maiduguri Mill Project in Nigeria,
which encompasses the entire range of postharvest activities,
is described as a model of an orderly, efficient postharvest

problems and increased international cooperation in research

Agricultural productivity gaps: a case study of
male preference in government policy
Staudt, Kathleen A.
Development and change, v.9, 1978, p.439-457 : En
* Microfiche not available paper copy only
The weighting of Kenya's agricultural assistance policy
towards men at the expense of women bodes ill for the
country's agricultural future, according to this case study of the
role of government in creating and/or perpetuating productivity
gaps between the sexes.
A controlled, cross-sectional sampling of farmers at two
locations in western Kenya shows that female-managed farms
have significantly less access to government provision of crop
information, training, and loans, than farms managed jointly by
women and men. This situation obtains even though women
farm managers, helped by information and labor inputs from the
communal agricultural groups to which most of them belong,
excel in key criteria crop diversification, farm income-generat-
ing orientation, and early adoption of hybrid maize for the
innovativeness on which the government focuses its agricultur-
al assistance efforts. In the long run, however, systematic
government neglect of women will have a negative impact on
women's ability to sustain innovative behavior and hence on
their agricultural productivity. Failure to redress this structural
disadvantage by channeling assistance on the basis of merit
rather than sex, it is concluded, will eventually lead to a decline
in the government's ability to raise agricultural productivity.

lactating women and weaning children are then examined and
the role of women in the village particularly their virtual
exclusion from decisionmaking and communal life is discuss-
ed; results of a survey examining the responsibilities of hus-
band and wife in the household economy are presented.
Concluding remarks recommend policies and programs de-
signed specifically to improve the health and status of Tanzani-
an women and children.

Data collection, site selection and farmer
participation in on-farm experimentation
Tripp, Robert

The experimentation phase of on-farm research is devoted
to designing trials to develop and test new technologies with
representative farmers. Description of the various types of data
available during this phase and guidelines for organizing their
collection are herein presented.
A discussion of trial site selection focuses on the impor-
tance of identifying recommendation domains (relatively ho-
mogenous groups of farmers), cooperating with local extension
agents, ensuring logistic feasibility, and identifying and commu-
nicating with farmer collaborators. A field book for recording
various types of data, from data on planting and trial plot (and
farmer) characteristics to data on trial results, is described (and
reproduced in an appendix), and data collection possibilities in
other areas (e.g., prices, weather, and farmer adoption of the
recommended practice) are discussed. A set of recommenda-
tions is appended to each major section of the paper. The
importance of flexibility is noted in conclusion, as is the
researcher's need to use on-farm experiments to establish a
partnership with farmers and extensionists which will benefit
the research.

In Tanzania, agricultural policies biased toward cash crops
and toward men as the sole agents of change have increased
women's workload, but not their access to the products of farm
labor. This study, based on extensive fieldwork during 1977-78,
focuses on the effects of such policies on the nutritional status
of Kurian women and children in the village of Nyamwigura.
Women's primary role in Tanzanian rural production and
reproduction, and the neglect of them in development planning,
are first discussed. The Kuria people, their land, and traditions
ruling the division of work and of labor returns are then
described. The transformation of agriculture during the colonial
period from diversified subsistence production to specialized
cultivation of maize as a cash crop is analyzed, as is the
postindependence villagization program. Both policies, it is
shown, have reinforced the traditional subordination of Tan-
zanian women. The combined effects of tradition and of these

Small farmer cropping systems for Central
America: final report
Tropical Agriculture Research and Training Center
1979, xii, 101p. : En
Provides final report (6/75-3/79) on a project implemented
by the Tropical Agriculture Research and Training Center
(CATIE) to create a coordinated regional research approach for
improving small farm cropping systems in Central America.
The project's key output was the development of a method-
ology or strategy for conducting on-farm research on small
farm cropping systems and its presentation in a procedural
guide. Some 115 field experiments were conducted, mostly on-
farm, yielding quantifiable and very promising research results
(the most important of which are indicated in the report), some
of them ready for validation. In addition, CATIE promoted
national research programs on cropping systems via training,
information dissemination, collaborating in field work with na-
tional staff, and helping to promote a collaborative research
effort among participating countries. Other project outputs
included collection of baseline data on small farmers' agronom-
ic, socioeconomic, and physiobiological environment; an exper-
iment conducted at CATIE headquarters on several cropping
systems commonly used by small farmers; the training of more
than 379 Latin American professionals, over 75% of them
Central Americans; the establishment of a documentation
center on tropical cropping systems (a 20-page bibliography
from which is appended); and the strengthening of CATIE's
professional ties to other international research centers. Cen-
tral American countries gave strong support to the project, and
national institutions collaborated in all aspects of it.

Based on field research carried out in 1967-1968 and on
literature studies, this second volume of a series on Ethiopia's
edible plants provides an integral overview of the country's
agricultural systems.
Initial chapters outline Ethiopia's geology, topography,
hydrography, and define its diverse climatic regions. Next, soil
taxonomy terms of the U.S. Department of Agriculture are used
to describe the soils of seven defined soil regions. Vegetation
zones and 16 vegetation types are described, followed by a brief
look at the country's ethnic and linguistic groups. Ethiopian
agriculture is then reviewed at length, with emphasis on the
country's 12 agroecological regions and the plants cultivated in
them, seed farming systems (mainly cereals, pulses, and oil
crops), the cultivation and use of ensat (a staple crop), shifting
cultivation, and pastoral systems. Where possible, linkages are
made between farmers' regional origins and their farming
systems and products. Finally, Ethiopia's marketing systems,
major foods, and nutritional status are described.

Risk, uncertainty, and the subsistence farmer:
technological innovation and resistance to
change in the context of survival
Wharton, Clifton R.
Michigan State University
Studies in economic anthropology, no.7, 1971, p.151-178 :
A subsistence farmer is one who consumes most of what he
produces, buys few items for his own needs, uses little outside
labor, employs primitive or traditional farming methods, has a
minimum standard of living, and bases his decisionmaking on
survival. The correlation between the prevalence of high levels
of risk and uncertainty among such farmers and their adoption
of technology is explored in this literature review.
Subsistence farmers' responsiveness to technological
change is described, along with possible sources of resistance,
causes of risk, and sources of uncertainty. A model is pre-
sented for determining minimum standards of subsistence
living at a certain time and how these standards change over
time. Three types of subsistence farms are then identified:
where the total product is food; where land and labor are the

Vol. I, 1984


major production factors; and where the family lives entirely
from the farm. Following a discussion of the effects of dynamic
interaction of risk, uncertainty, and subsistence upon techno-
logical innovation, it is concluded that increased profit may be
less important in a subsistence or barter economy than are
increased security and survival, and that quantification of risk
aversion is needed when evaluating technology adoption or
rejection. Appended is a 91-item bibliography (1948-69).

Nutritional component of farming systems
Whelan, William P.
Rutgers University. Cook College. International Agricultural
and Food Program
(1983), 18p. : En
Improvements in crop yield and farmer income achieved
through farming systems research (FSR) projects do not in
themselves signify improved household nutrition. Presented
here is a strategy for incorporating nutritional considerations
into FSR.
Variables that can provide important nutritional information
during the FSR design stage are discussed first. The author
considers and rejects several possible variables (i.e.,
anthropometric data, dietary intake, income and expenditure
levels), outlining the difficulties of accurately identifying the
malnourished using these approaches. Suggested instead is
the subsistence potential ratio (SPR), the ratio of a household's
ability to feed itself to its need to feed itself. The SPR, useful in
measuring both the source and level of consumption, distin-
guishes between groups with different nutritional status and
FSR's effects on them, has acceptable levels of accuracy, and
is based upon easily and cheaply obtainable data.
Next, consideration is given to ongoing and ex post analysis
of FSR's nutritional impact. Ongoing analysis is necessary to
see whether changes in farming systems lead to short-term
food scarcity. Ex post analysis requires a solid theoretical basis
(e.g., the theory of the household-firm), a longer data collection
cycle, and calculation of income elasticities, and should ad-
dress the extent to which FSR benefits large rather than small
farmers. Careful ex post analysis can help to identify ex ante
variables for future FSR.

May 1981, x, 111p. : En
Existing research and development (R&D) strategies have
tended to support farmers already in relatively advantageous

positions and to ignore the majority of small farmers who
struggle under less favorable conditions. This state-of-the-art
paper presents an overview of past R&D efforts and proposes
a new R&D strategy to assist the rural poor.
After examining limitations of and lessons to be learned
from conventional R&D strategies, the author describes the
agricultural R&D strategy used by institutions in Bangladesh,
Ethiopia, Mexico, and Colombia which emphasizes participa-
tion by small farmers and incorporates animal husbandry as an
integral element. Efforts to build a farming systems research
strategy into R&D programs are then examined, using exam-
ples from Guatemala and Honduras.
The author concludes that any new R&D model should
involve research conducted on small farmers' actual fields;
farmer participation in research and extension; and a major
emphasis on cropping and farming systems, experimentation,
and interdisciplinary collaboration. In order to enhance the
quality of life among small farmers and to build material
resources into the organizational base, linkages are required
between local farmer organizations and government bureauc-
racies. Attached is a list of 107 references (1911-1981).

A state of the art summary, this 34-paper volume consti-
tutes the proceedings of a 1/79 international workshop on
intercropping hosted by ICRISAT. A workshop paper by an
ICRISAT agronomist introduces the volume. Papers from Ses-
sion 1, on agronomy, consist mostly of case studies from India,
Brazil, West Africa (Nigeria, Volta), East Africa (Swaziland,
Kenya, Uganda), and on genotypes. Papers from Session 2, on
physiological aspects, treat: leaf canopies and plant light use
(light use efficiency, plant interactions and productivity in com-
plex mixtures, canopy development and light interception in
sorghum/pigeonpea intercropping); nutrient interactions and
rooting patterns (interactions below ground, leaf canopy and
rooting pattern in pearl millet/groundnut intercropping, nitrogen
response in sorghum/pigeonpea intercropping); and nitrogen
fixation in sorghum/chickpea intercropping. Three papers on
weeds and pests are drawn from Session 3. Papers from
Session 4, on evaluating intercropping systems, discuss: statis-
tical considerations and experimental designs; yield stability
and economics (intercropping in traditional and dryland sys-
tems, stability of pigeonpea/sorghum intercropping); and
operational management (including a paper on seeding and
interculture mechanization requirements in India). Summaries
of individual and plenary session discussions are provided.
Appendices include French translations of abstracts of work-
shop papers and a 20-page, multi-language bibliography

Efforts of the Economics Program at the International Maize
and Wheat Improvement Center (CIMMYT) to gear research on
new technologies to farmers' real production problems and
decisionmaking processes are reviewed. The key elements of
the CIMMYT research procedures are: (1) ascertaining the
circumstances and practices of representative farmers; (2)
undertaking on-farm (and sometimes on-station) trials; (3)
formulating recommendations and examining their implications
for prices, markets, etc.; and (4) evaluating the new technolo-
This methodology, the authors note, is directed at finding
technologies that farmers (CIMMYT's primary clients) will use,
i.e., those which are consistent with farmers' natural and
economic circumstances and which promise improved incomes
with little risk. Thus, the CIMMYT program emphasizes collabo-
ration between economists and biological scientists, early
application of findings, and treatment of a single crop or
mixture, and aims at useful, not necessarily optimal, technolo-
gies. The process systematically focuses on major constraints
to production, provides for continuing and immediate improve-
ments through research and feedback, and counts on individu-
al farmers to make adjustments in terms of their own special

Methodology for on-farm cropping systems

1981, viii, 147p. : En
* IRRI, P.O. Box 933, Manila, Philippines
On-farm cropping systems research seeks to identify a
technology, acceptable to farmers, that will increase production
yields and/or cropping intensity while minimizing the detrimen-
tal effects of introduced changes. Described herein, for the
benefit of both professional researchers and those active in

research management and training, are research methods
which were developed and adapted for the study of both
dryland and wetland rice-based cropping systems.
The manual begins by discussing general concepts: the
definition of cropping systems and of cropping systems re-
search; and the importance of on-farm research as a means of
finding improved cropping systems that are acceptable to
farmers. Methods for site selection, site description, design of
cropping patterns, and on-farm testing of such patterns are
then described. In the final chapter, ways in which research
results can be extended to a greater area and to farmers
through production programs are discussed. This chapter, less
detailed than those preceding, is included to emphasize the
need for researchers to consider the consequences of their
results in production programs and to stress that on-farm
research is beneficial only when farmers adopt recommended
practices. Details of several research or analytical techniques
are provided in appendices focusing on fertilizer rates, weed
control, varietal testing, and cropping pattern monitoring.

Caqueza: living rural development

The Caqueza Project was a rural development effort con-
ducted in eastern Colombia by the Agricultural Institute (ICA),
the research and extension arm of the Colombian Ministry of
Agriculture. This book records the history of the project's first 5
years (1971-76).
Part I describes the evolution of rural development philoso-
phy in Colombia and outlines ICA's rural development model
for the 1970's; specific information on the Caqueza Project is
included. Part II describes chronologically the 5-year span of
project activities and lessons, while Part III analyzes in some
depth the, research methodology tested during the project and
the extent of its adoption by farmers. Part IV examines non-
technical factors influencing adoption rates, such as risk, credit,
marketing, training, and buffer institutions. A final section
reviews the various evaluations of the project and provides an
overview of the project as a whole.
Although it helped only a small minority of farmers, Caqueza
strongly influenced ICA in terms of staff training and research
policy and is the closest Colombia has come to an open
dialogue among planners, agriculturalists, and farmers, the
interaction among whom is the primary focus of the book's
narrative. A 144-item bibliography (1957-77) is appended.
