supplementary relationships between resources and enterprises, and the derivation of solutions compatible with the needs and capacities of farming families. The farming systems farmers practiced traditionally recognized such relationships-for example crops and livestock, staggered planting dates, etc.' To ensure that the integrative and beneficial relationships are adequately considered and exploited requires a multidisciplinary team-both technical and social scientists-working together at all four stages of the research process. 5.6 The process of FSR is recognized as being dynamic and iterative with linkages in both directions between farmers, research workers, and funding agencies, rather than simply the presence of forward linkages characteristic of the "top-down" approach. The iterative characteristic can improve the efficiency of the research process through providing-a means to fine-tune improved technologies to a specific locale. 5.7 Finally, FSR complements, and does not compete with, other research approaches. The complementarity is illustrated through FSR contributing in two ways: (a) Fine-tuning through adaptive testing at the farm level those technologies developed on experiment stations through "upstream" FSR and the more conventional reductionist approach (both contribute to the "body of knowledge"). Successful testing gives rise to successful dissemination (all other things being equal), resulting in improvement of farming families' welfare. (b) Failure under adaptive testing at the farm level results in closer specification of requirements for improved technology development that can be fed back to experiment station based research programs outside the FSR program itself. Hopefully, this will contribute to the development of improved technologies that will improve the welfare of farming families in the future. 6. Methodological problems of the FSAR 6.1 Due to the fact that the methodology for undertaking "downstream" FSR is still going through a period of evolution, a large variety of methodological issues require resolution. Not surprisingly perhaps, there are often considerable differences in opinion as to how severe they are and how they should be dealt with. Some of the most frequently mentioned methodological issues follow. 6.2 How holistic should FSR be? As mentioned earlier, the methodological problems increase as the FSR program becomes more holistic, i.e., the ratio of variables to parameters becomes higher. Also stressed earlier was the fact that the present state of the arts of undertaking FSR means that most current work is on the crop process and is largely confined to development of improved technologies. Practical problems also restricting the scope of "downstream" FSR are the mandates of institutions in which they are located, i.e., usually technical crop research institutes, poor or weak linkages with other research institutions, and policy-making and farmer contact agencies.
