Farming Systems Research Group WORKING PAPERS

The papers in this series were prepared during the 1980 1981
academic year by members of the Michigan State University Farming Systems
Research Group. Papers one through nine were prepared by individual
members of the group, after much discussion, and were reviewed by members
of the group prior to final revision by the authors. However, each of
the papers represents the author's personal perspectives on Farming
Systems Research. Each paper is different from the others. All papers
are an attempt to answer the following questions:

From the perspective of my discipline what is Farming Systems

What research has been done in my discipline which relates directly
to Farming Systems Research?

What opportunities are there for further research from the perspective
of my discipline?

What assistance would scholars from my discipline need from other
disciplines in order to carry out Farming Systems Research?

Each individual responded to these questions in his own way. Paper
number ten is an attempt to summarize the perspectives of the various
disciplines represented, identifying commonalities and differences. Paper
eleven sets forth the recommendations of the group for further work in
this field at Michigan State University.

The Farming Systems Research Approach
in the Agricultural Engineering Field


Merle L. Esmay


This paper attempts to define and discuss Farming Systems Research (FSR)

in a somewhat narrow sense as to how the MSU Task Force may be able to pro-

gress in a meaningful and practical manner. Of particular concern is how

professionals from the existing discipline may play a role in FSR. Regard-

less of what may develop in the future as to the interdisciplinary nature of

FSR, or on the other hand the development and training of FSR specialists;

the movement to FSR must start from where we are now in the various pro-

fessional disciplines.


First, it should be recognized that FSR consists of an interdiscipli-

nary approach to development. The term interdisciplinary is used rather than

multidisciplinary to differentiate that specific disciplines are necessary in

contrast to a broad generalized array of disciplines. In the arena of Agri-

culture and food production, in which Title XII is involved, there are basic

requirements for professionals from four disciplines; (1) biology (2) physi-

cal technology, (3) economics and (4) sociology.

Second, the FSR approach is focused towards the farm family and the

family farmer.

I would like to narrow this to a focus on small farms in developing countries.

Small farms are defined as average sized farms and smaller in whatever country,

region or district one might be concerned. It is the author's belief that

FSR evolved mainly because of the need to cope with the problems of small

farms for which other educational, extension and developmental approaches

and institutions have experienced various degrees of failure. The develop-

ing country constraint was placed on this FSR definition because of the in-

ternational focus of the Title XII strengthening grant that is being used

to support the MSU FSR task force. This is not to argue that FSR cannot be

applied to large farms in any country, but rather to focus more specifically

on how FSR might help solve the burdensome problems of the small farmers,

particularly in developing countries.

Third, it should be recognized that FSR has a positive connotation of

improvement and development. It thus, should not be interpreted as a pro-

gram designed to maintain the status-quo of the small farmers in their

lock-in subsistence existence. FSR has the general objective of improving

the quality of life of small farm families, but specifically in the sense of

improving food production and financial returns through the application of

appropriate technologies.

My definition is then that FSR consists of an interdisciplinary approach

to the development and introduction of improved technologies for increased

food production appropriate to the needs and circumstances of small farmers.

New technologies are necessary as farmers have pretty well maximized outputs

from traditional inputs and methods. An increase in production is assumed

as the principle way to increase income and thus enhance the quality of

life for the farm families. Production is interpreted to include all pro-

duction and post production operations and activities. Producing more has no


benefit if it doesn't reach the consumer as a high quality product. Also

the production should be studied and evaluated with respect to equal benefit

to all. This is the reason for the focus on the small farmers as they have

traditionally received the short-end of returns from new technologies.

Heady (1973) stated that a structure of research is needed that will

facilitate a synthesizing, integrative, team-oriented outlook rather than

one that is analytical, compartmentalizing and disciplinary. A successful

FSR approach should do this. Dillon (1976) stated that before the advent of

systems thinking, scientists tended to derive understanding of the function-

ing of the whole from the mechanical structure of the parts. He called this

reductionism and mechanism; and suggests that expansionism,teleology, and

synthesis are necessary modes of thought in understanding the world. The

functioning of the whole must first be considered and understood before

dissecting it into parts. A system is more than a sum of its parts. The

teleological or means-ends approach is recognized as a valid scientific method

for the study of social systems or systems with social effects. Goal seeking

and goal-setting are intrinsic parts of such research.

The Green Revolution

Technologies may be either biological, physical or social in nature.

Considerable emphasis has been given to biological breakthroughs of high

yielding plant varieties (HYV) of the important food crops of rice, wheat,

maize and others. During the early phases (1950's and 60's) of such develop-

ment, referred to by some as the green revolution", there was an associated

need for new and different inputs to attain higher yields. Many of these

inputs, even though prescribed by biologists, were physical in nature, such

as; the application of fertilizers and pesticides (the manufacturing of them

was also a physical process), water control (irrigation and/or drainage)


the development of a plant growth micro environment through soil manipula-

tion processes of primary and secondary tillage. Weed control has generally

been a physical process prior to the advent of chemical control and even

then must be properly applied as to chemical fertilizers and pesticides.

When some or all of these physical technologies were not carried out accord-

ing to prescription the early HYV's did not yield as much consistently as

the old indigenous varieites. This introduced a risk factor for the planter,

as well as an increased investment for inputs particularly if all of the

prescribed practices were not followed. The more recent emphasis on HYV's

has been for the crops to produce more under the traditional environment of

the old indigenous varieties.

A biological characteristic that was apparently overlooked in the early

development of higher yielding rice varieties was the resulting easy shatter-

ing nature (separation of the seed kernels from the plant panicles). This

change of a biological factor compared to the old accustomed indigenous

varieties necessitated numerous physical changes in harvesting methods and

post harvest operations to minimize what would otherwise be excessive losses.

Once the harvested rice plant (which includes some portion of the plant

stems) is to be threshed, ease of separation (high shattering character-

istic) of the seed from the rest of the plant is desirable (although mechan-

ical threshing technology does overcome). The problem lies in the necessity

of harvesting the HYV's early enough, while the seed moisture content was

still at least 20 percent (wet basis) or above, to minimize pre-harvest

in-field shattering. Then the harvested crop (stalk paddy) must be handled

in such a way to minimize harvesting, drying and transporting (shattering)


Possibly some early collaboration between the biological and physical

scientists on the shattering problem would have made the introduction of the


new biological technology more successful. One can extrapolate the HYV

example further to imply that if agricultural economists had been more involved

early on, there would have been a better understanding (possibly before the

introduction) of cost and returns as related to risk; particularly for the

small subsistence farmer who traditionally has had neither input investment

resources nor the capability of risk without suffering dire circumstances

(possibly hunger) of a crop failure. Social-cultural scientists could have

helped provide an early understanding of the small subsistence families as to

constraints, capabilities, aspirations and traditions.

I use the example of the early HYV's and the "green revolution" not to

emphasize its' negative characteristics, as I give it an overall rating

of "successful". We, however, live in an imperfect world which means there

is always room for improvement. The "criticism" should be used for construc-

tive discussion in the search for improved introduction processes through

the application of the Farming Systems Research approach. I do not enjoy

researching projects after the fact (the introduction of them) in order to

determine how unsuccessful they were in terms of income distribution, labor

utilization, migration, etc. We must, however, learn from experience in

order to improve future programs. The greatest challenge is to develop new

programs that will stand the test of time and subsequent investigations.

The Farming Systems Research approach can help identify problems before

they occur.

Holistic Approach to FSR

Farming Systems Research (FSR) should be holistic in its' approach,

but not necessarily designed to change the entire system. A FSR approach

might be partitioned to study the development and adaptation of a particu-

lar type of technology, but with a holistic understanding of the farm

system. (Rohrbach, 1980).


For discussion purposes I will describe a post rice production (in-

cludes harvesting as well as post harvest operations) technology and losses

in a Southeast Asia program in which I have been involved for the past

five years with a number of Doctoral students. One of the first procedural

decisions made was that studies and measurements would be made strictly on

farmer operations. Different methods and technology would be studied in

so far as they were now being used by some farm operators.

Existing technology was identified and evaluated as to losses, labor

utilization, possible harvesting delay constraints and other cost and re-

turn factors. A part of the evaluation phase was to formulate computer

systems models to simulate in so far as possible the utilization of tech-

nology under farmer operation conditions. Simulation studies were then made

to identify comparative advantages, constraints and undesirable features.

Systems Modeling

The systems modeling was flexible to the extent that other technology

systems could be introduced for simulation studies if and when desirable.

The study of new technology would depend mainly on the availability of rep-

resentative operational data under farmer conditions. Although some sur-

vey data were obtained in each study to describe farmer conditions, they

fall considerably short of a true FSR approach in which understanding of

the farm families and all of their constraints and incentives would be

given primary attention.

The Nature of Change

The doctoral dissertation research projects did not follow through

with the verification and acceptability of new improved technology in the

conventional sense of adoption. A central Java study by David Gaiser in

1979-80 provided some insight on a harvesting technology change that was

taking place. The farmers (rice producers) were breaking the old traditional


ani-ani harvesting system in favor of a 79 percent more labor efficient

sickle cutting system by selling their pre-harvested rice crop to traders.

The out-of-village traders would then move in with sickle cutting crews

and harvest the crop quickly and move it out for threshing, drying and

milling (possible storage) someplace else.

In explanation, the ani-ani system included more than the physical

technology of cutting the individual stems of rice with a small knife in

one hand and gathering in the other. It also carried with it the social

priviledge of all local disadvantaged family members (the landless) to

come in and harvest all the land owners rice crops for a share (generally

around 10%). The change to the HYV rice crops made the ani ani systems

much less appropriate technically because of the higher yields (many more

panicles), shorter stems and higher shattering nature (higher harvest shat-

tering losses). From the farmers standpoint the traditional ani-ani system

was completely outside of the farmers control. In some cases large numbers

of people would move into a farmer's field, many of whom he might not know.

Their incentive to harvest all of the rice with a minimum of loss was not

particularly high. In contrast to too many harvesters Gaiser's central

Java study indicated that rice farmers were experiencing delays of

many days before ani-ani harvest crews were available.

Socially, within the village, farmers seemed constrained to not hire

their own sickle cutting crews even though delays in harvesting were occur-

ing. However, to break the system farmers began selling the standing crops

to "outsiders" who apparently had no qualms about bringing in the sickle

cutting crews. The unfortunate aspect of this type of a "forced" change

rather than a more desirably planned one is that the traders brought in

outsiders to cut the crop which entirely eliminated any local labor. Also

the traders moved the harvested stalk-paddy crop out of the area for

threshing, drying and milling. All of these value adding operations were

thus lost to the local labor. Individual farmer control, particularly

through the cutting, threshing and drying stages, would benefit local

laborers as well as the farmer, and in general keep the returns of these

value increasing operations within the villages.

In summary of the post rice harvest changes taking place in Indonesia

most social planners saw the substitution of the 78 percent, more-efficient,

sickle cutting as an undesirable change. Unfortunately, when change was

left to the farmers, who are not necessarily social conscious, the local

labor was cut out of nearly all of the post harvest operations. Also the

traders will tend to mechanize the cutting, threshing and drying as soon

as feasible (cost return wise) regardless of village labor unemployment

conditions. A thorough Farming Systems Research approach to this problem

at an early stage might have been able to provide recommendations and

planning guidance to direct change into a more overall favorable direction.

Now changing the established trader system will be most difficult. An

early FSR study would have developed an understanding of the farm families

and also the disadvantaged family members in order to consider the aspira-

tions and goals of all concerned.

Land Preparation Mechanization

Another example of where and how Farming Systems Research (FSR) might

have been beneficially applied is with reference to the question of

mechanizing rice paddy land preparation in Indonesia. Some mechanical

power was introduced for the primary tillage operation during the past

few years Indonesia, particularly the island of Java, has a dense popu-

lation; therefore, the problem of providing meaningful employment for all

of the people is critical. Mechanization that displaces people from labor


intensive operations is not necessarily desirable. The appropriateness

of any agricultural mechanization is thus questionable.

The question of appropriateness of mechanization for rice land prep-

aration in Indonesia is presently polarized along professional lines into

the "anti" group and the "pro" group. The "anti" group tend to be mainly

the agricultural (Socio) Economists and the "pro" group the Agricultural

technologists (Engineers). I doubt if many of the professionals of

either group feel comfortable in being classified as absolutely "anti" or

"pro". The lack of communications between the two professional groups

has, however, allowed if not stimulated the extreme positions taken by


There is a great need for a true FSR approach to the evaluation and

planning for appropriate agricultural mechanization in Indonesia. Unfortu-

nately such a program has not been formulated. Instead an extensive sur-

vey has been undertaken, mainly by Agricultural Economists, to prove that

mechanization is uneconomical to the tractor owners (buyers). A paper

was presented at the Regional Seminar on Appropriate Mechanization for Rural

Development with Special Reference to Small Farming in the ASEAN countries

in Jakarta January 26-31, 1981. The evaluation project and the title were

entitled "The Consequences of Land Preparation Mechanization in Indones-

ia: South Sulawesi and West Java". The paper was presented by Ir. Mamum

and the project is headed by Dr. R.H. Bernsten of IRRI/CRIA Bogor, Indo-


The project and paper title is quite appropriate, but the approach

presented in this first paper based on one years preliminary data was to

prove financially that the mini-tractors in South Sulawesi and power til-

lers of West Java were uneconomical to the owners. The numerical analysis

made was based upon unsupportable assumptions of cost of operation, length

of life, day length, and total time of operation of tractors per year.

Such data could be obtained by studying the experiences of the tractor

owners. But this was not done nor at least the data were not included

in the paper presented. Such a study if and when undertaken would need

to be carried out mainly by technologists thoroughly versed in the physical

knowledge of tractor operations and performance.

On the financial side of the cost and returns analysis presented in

the seminar paper; there was no mention made of the fact that the contract

price for custom work was a "set" price by government, and that the trac-

tors were purchased (obtained) by farmers through a government program

without down payment and with two installments due per year which are

not enforced. Apparently over half of the tractor buyers were default-

ing on their payments. It seems to me that a true economic analysis

should be made which would recognize all of the incentives and constraints

for owning tractors.

I tend to believe that the imported, expensive, complex small four

wheeled tractors are not economical nor appropriate for Indonesia but the

survey approach and financial analysis is not proving it. A coordinated

FSR approach to this problem with a number of disciplines involved could

obtain and present supportable documentation for proving the inappropriate-

ness of the tractor mechanization. Agricultural economists need to e-

valuate the overall economics of the tractors including the effects of

the subsidized prices and set fees; while Agricultural Engineers need to

study in detail the experience of the tractor owners and operators. Other

socio cultural people need to be included in order to better understand

the farmers, laborers and rural conditions.

Under the circumstances of the government program for introduction of

the tractors, I believe that the tractor mechanized land preparation is

probably economical for both farmers contracting for tractor tillage and

for the tractor owners. The fee for tillage is set arbitrarily low to

make it attractive for the farmers contracting for work done. The own-

ers are not paying for the tractors under the "soft loan" arrangements

so ownership is financially favorable for the owners under these fixed cir-

cumstances. Unfortunately these financial conditions are unrelated to the

overall economics and broader effects of mechanization on unemployment

and income distribution in the rural areas.

My bias is that some mechanization of land preparation is inevitable,
particularly in the islands^of Java. There is no way that the rural people

can or should be "forced" to continue to grow rice by human labor in the

mud when the city people are riding motor bikes and automobiles. I be-

lieve that local manufactured, simpler, less costly tractors and machinery

are more appropriate in the long run. Farming Systems Research would, how-

ever, provide guidance so that direction does not depend on biases and

opinions of individuals or professional groups.

Farming systems research plans should depend directly on qualified

professionals from a minimum of the basic technology fields of biology,

physical technology, economics and sociology. There are exceptions when

one person might qualify to cover two of these fields. Such a trend

should, however, be discouraged or the interdisciplinary approach will

be defeated. The excuse today for the single discipline approach is often

that one person feels that he or she can cover 2 or 3 or more fields ade-
