Evaluates the productivity of grade Boran cattle maintained by chemoprophylaxis under severe trypanosomiasis risk at Mkwaja ranch, Tanzania; uses data based on more than 20,000 calving records over the 10-year period from 1973 to 1982; discusses environmental influences on performance traits and links between tsetse population dynamics & cattle; includes comparison of Boran genotypes and its effect on pre-weaning growth characters.

Evaluates the productivity of transhumant Fulani cattle in the inner Niger delta of Mali. Summarises the results of the animal productivity study extending from December 1978 - March 1983, which indicated high calf mortality, low reproductive performance and moderate milk production. Identifies constraints limiting the productivity of Sudanese Fulani cattle and suggests interventions aimed at eliminating or ameliorating these constraints

Presents papers dealing with the use of crop residues as livestock feed in smallholder crop/livestock farming systems, and the role of plant breeding in maintaining or improving their nutritive value. Discusses factors limiting the nutritive value of crop residues, and the effect of genotype and environment on the nutritive value of crop residues. Outlines perspectives and implications for crop improvement programmes. Includes recommendations.

This meta-synthesis of national climate change adaptation plans, policies and processes spans twelve countries at various stages of adaptation planning and implementation, in three priority CCAFS regions: West Africa (Burkina Faso, Ghana, Mali, Niger, Se?negal), East Africa (Ethiopia, Kenya, Tanzania, Uganda) and South Asia (Bangladesh, India, Nepal).

This document presents the proceedings of the international conference held at the United Nations Economic Commission for Africa, Addis Ababa, Ethiopia, April 24-26, 2002.
