The problem of vegetation degradation in Kenya's semi-arid areas must be addressed, if these areas are to support the increasing human and livestock population. However, efforts to rcvcgctatc denuded rangelands will be beneficial only if the right species and cultural practices arc employed.

This thesis gives an overview of the Maasai livestock economy as it has developed between 1890 and 1990. Particularly, it analyses the processes and policies of land use and landownership of the Maasai pastoral areas in Kajiado district, Kenya, from the arrival of the Europeans until the recent massive individualization of land tenure.

Los tcnicos forestales y los administradores de recursos naturales entendieron muy poco y mal los mltiples usos que los campesinos hicieron de las formaciones forestales en el curso de los milenios, ampliamente documentados en un artculo sobre las tcnicas de ordenacin de tierras arboladas aparecido en el nmero 160 de Unasylva.

Such is the vagary of rainfall throughout Africa's rangelands that almost all pastoral communities face cycles of good and hardship years.

The paper is divided into four chapters. The frist chapter is the introduction. Chapter two discusses the conceptualisation of the farming system with reference to the livestock component and reviews some alternative typologies that have been employed or proposed. A typological framework that is consistent with ILCA's objectives is then outlined.

Outlines the types of reforms introduced in animal health services over the past decade, summarises past experiences, provides a preliminary assessment of their impact, and indicates what lessons need to be taken into account in future policy adjustments and project investments. The discussion concentrates on World Bank- supported accessibility of the data to the authors.

This study is part of a larger study on dairy marketing in Ethiopia, and concentrates on the producers'end of the marketing chain. Specifically, the markets of first sale used by dairy producers were identified and the marketing patterns of three categories of dairy producers (intra-urban, peri-urban and peasant) were investigated.

Presents ILCA's achievements in 1990 in a popular, easily read style. The Cattle Milk and Meat Thrust highlight focusses on peri-urban dairying, and particularly the work of collaborative programme with KARI. The highlights of the Small Ruminant Meat and Milk Thrust are linked by their focus on interactions between animals and other components of the agricultural system.

The first chapter gives a brief description of a pastoral production system, as envisaged by the study team and outlines the multi-disciplinary approach of the study, its sampling design and the data collected. Chapters 2 & 3 describe Kenya's biophysical and socio-economic environments, within which the Maasai livestock production system operates.
