This document reports the results of a small meeting of social scientists from ILCA and IFPRI held at ILCA. The workshop was conceived to summarize the results of studies previously conducted by ILCA and others, to identify priorities for future research; to provide guidance for future research - problems, methodology, locations, and resource requirements, and to consider specific proposals for future research and evaluate the areas of complementarity and/or overlap with other past or current projects.

This report at first presents summary of a talk given at ILRAD. Following this, it discusses tickborne diseases particularly epidemiology and biology, parasite antigens with vaccine, vaccine development etc. The report also reviews trypanosomiasis and topics covered within parasite-host interaction, anemia and others. In addition, socioeconomics and environmental impact, cooperative programs, training and information, research support, etc are outlined in the report.

This document summarises the major discussions, findings and recommendations of the conference convened by ILCA and its cosponsors to bring together national and international experts in livestock nutrition and management, ecology, agronomy, soil science and socio-economics to address fundamental issues of nutrient balances, agricultural productivity and the well being of the people, livestock and environment of sub-Saharan Africa.

Session one of this report highlights ILRAD's research programs and the modelling needs of ILRAD and FAO. Session two deals with vector and helminth population dynamics with particular reference to ticks, tsetse and helminth. Parasite transmission and host parasite interaction are discussed in sessions three and four respectively. These two sessions deal with theileria, trypanosomes and leishmania. Parasite variations and polymorphism is the topic of session five. Session six discusses the effect of disease control programs and session seven reviews modelling systems.

The authors started the discussion with the fundamental question: why are property rights important? The central hypothesis of this collaborative venture is that inappropriate property rights institutions lead to resource degradation. Two cases were distinguished: single-user resources and multiple-use resources. A good example of a single-user resource is land. Absence of secure property rights will result in land degradation, as incentives to improve the resource base do not exist under such conditions.

This report is divided into seven sections. The first section deals with biology of Stylosanthes and its importance in West Africa and Latin America. The second section presents papers on the screening and evaluation of Stylosanthes germplasm. This includes genetic diversity, genetic resources, species screening, multi-locational testing and evaluation of accessions. The third part discusses the dynamics, nutrient requirements, and pests and diseases of Stylosanthes species. Section four looks at Stylosanthes-based pastures for livestock production.

This document is divided in eight chapters. The first chapter reviews rangelands and rangeland development in Ethiopia. The second chapter is an introduction to the Borana Plateau with ref. to natural resources and pastoral society. It reviews secondary information on geology and sociology, as well as original information on climate, soils, wildlife, plant ecology and water resources for the central Borana Plateau. Chapter three deals with vegetation dynamics and resource use.

This workshop was conceived in recognition of the fact that, over the years, a great deal of research has been conducted on trypanotolerance. With the advent of new and powerful means to identify markers and genes controlling traits of interest, and with the developments in animal breeding bringing greater speed in dissemination of desirable genotypes, there is increasing interest in trypanotolerance as a way forward in trypanosomiasis control.
