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. The biophysical environment of the study site is described in detail in Chapter 4. Chapter 5 describes the social organization of the Maasai and how it affects their use of livestock and grazing resources.

Presents papers and abstracts on the management of vertisols in sub-Saharan Africa and other parts of the world. Overviews the importance, distribution, agroclimatology and properties of vertisols and the Indian Vertisol technology experience. Reviews resource assessment and management and highlights inter-institutional modes of operation and networking concepts in Vertisol research and development.

Research carried out to evaluate management options and animal production potential of native and improved pastures in savanna regions of tropical America is reviewed, with emphasis on Colombia's Eastern Plains. In areas with limited infrastructure native grasses are the main forage resource and weight gains of cattle grazing these native pastures with burning and mineral supplementation vary from 70 to 90 kg/hd and from 15 to 20 kg/ha.

Mapaz helps policymakers and scientists target research and development or conservation activities in the Amazon by pulling together information on elements such as deforestation, biomass, species diversity, population, poverty and regional land use. Users can define their own geographic areas or select existing administrative boundaries to get spatial information for that area in the form of maps and tables. For example, MAPAZ calculates biomass,

Description of geographical aspects of the Subhumid Zone of West Africa and economic and sociological aspects of the Fulani ethnic group, w. emphasis on fodder resources, range management, livestock raising, livestock management, and animal diseases, w. analysis of land use & land development strategies, and directions for future research.

The main aim of land preparation is to modify and manipulate the land features so as to create favorable environment for seed establishment and crop growth. The research and Development in this field must take into account the traditional practices used by the farming community. This case study gives a brief description of farmers' management of Vertisols and soils with 'Vertic' properties and the Development of the low cost broad bed maker (BBM) for facilitating surface drainage.

Few studies of land-use/land-cover change provide an integrated assessment of the driving forces and consequences of that change, particularly in Africa. Our objectives were to determine how driving forces at different scales change over time, how these forces affect the dynamics and patterns of land use/land cover, and how land-use/land-cover change affects ecological properties at the landscape scale.
