PREFACE
One of the problems facing most Farming Systems Research and Extension (FSR/E) 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as "ephemeral" or "fugitive" and consists of trip reports, sections of the annual reports from national programs, and unpublished manuscripts from the many seminars and workshops held on FSR topics.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 theirwork 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 StatesAgency 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 their annotation 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 second volume of the bibliography. A third volume is currently in production. 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:

This procedure has been tested in several workshops in Thailand over the past 5 years.
Participants in the analysis begin by defining its objectives and identifying relevant systems, their boundaries, and hierarchic arrangement. Pattern analysis follows: a systems analysis by all the participating disciplines in terms of space, time, flows, and decisions. These patterns are crucial in determining the important properties of the agroecosystem being analyzed, i.e., its productivity, stability, sustainability, and equitability. The outcome of pattern analysis is a set of agreed-upon key questions for future research or a set of tentative guidelines for development. The procedure can be applied at any stage of a project, but is particularly useful at the beginning when data

The complexity of livestock production systems in SubSaharan Africa and the multiple objectives of livestock producers require the study of whole systems rather than of components; the livestock systems research practiced by the International Livestock Centre for Africa (ILCA) represents such an approach. This report overviews ILCA's methodology and highlights some of its results.

The initial steps in the on-farm research process are first described assessment of the farmers' circumstances (e.g., climate, farming practices, markets), definition of the recommendation domains, and identification of research opportunities. Next, the paper reviews the implementation of the first, second, third, and fourth cycles of experiments; for each cycle the experimental strategies, trial management, integration of experimental and survey results, and implications for further research are discussed. The program resulted in two recommendations nitrogen fertilization and an appropriate maize variety for extension to Les Cayes farmers. Furthermore, based on a 1983 evaluation of the program, the on-farm research methodologies used at Les Cayes will be extended to other regions and target crops in Haiti beginning in early 1985.
