Report of the Task Force on Sustainable Agriculture established at ICW94 to clarify concepts and priority themes and recommend the role for CGIAR centers in addressing issues relative to sustainable agriculture. The report was presented by Task Force Chair Rudy Rabbinge at the CGIAR Mid Term Meeting in Nairobi, May 1995. This task force was twinned with the Task Force on Ecoregional Approaches to Research which also reported at MTM95.Four key conclusions of the report were that there is no single remedy to problems of sustainability; that CGIAR centers must adjust the way they conduct research toward more collaboration with others; that centers must recognize the individual characteristics of different ecoregions; and that sufficient financial resources should be available to ensure the success of sustainability oriented research. Possible gaps in the CGIAR research agenda were listed. The approach needed to integrate production, environment, and sustainability concerns.Annexes deal with the evolution of CGIAR research, the CGIAR response to Agenda 21, the concept of production ecology, and priority themes for sustainability research. A list of task force members is attached. Agenda document at the CGIAR meeting in May 1995
