Outlines some of the work being done by ILCA in the field of agroecological zonation and the use of models to predict the effect of environment on pastoral and agricultural systems. Includes plans for future developments and the potential benefits of the work.

This audiotutorial unit (cassette, printed script, 93 color slides, Study guide, self-evaluation test), prepared by the Communications Support Unit at CIAT, is available for use with a manually or automatically synchronized slide projector/cassette tape recorder. Each unit is available from the Distribution Office at a cost of US$ 50; photocopies of the study guide alone can be obtained from the Cassava Information Center. One of the main factors limiting to cassava production is disease.

This audiotutorial unit (cassette, printed script, 80 color slides, study guide, self-evaluation test), prepared by the Communications Support Unit at CIAT, is available for use with a manually or automatically synchronized slide projector/cassette tape recorder. Each unitis available from the Distribution Office at a cost of US$50; photocopies of the study guide alone can be obtained from the Bean Information Center. Pests are one of the main factors limiting bean production. Of the 200 species of insects and mites, however, only a few cause losses of economic importance.

Inadequate feed and nutrition are major constraints to livestock production in sub-Saharan Africa. National and international research agencies, including the International Livestock Research Institute (ILRI), have developed several feed production and utilisation technologies. However, adoption of these technologies has so far been low. Identification of the major socio-economic and policy factors influencing the adoption of improved feed technologies is required to help design policy and institutional interventions to improve adoption.
