Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.

Over millions of years, nature has built up an intricate system of relationship of exchange and mutual dependence among its elements - land, water, air, forest, sunlight and living things - to create what we call the ecosystem. It is the life support system of all living things on this planet and provides not oniy the daily needs but also saves resources for future generations. But this very life support system is endangered by man's aggression against nature. In the last few decades, the aggression has reached unprecedented levels.

This paper states that, in Africa, smallholder agriculture is the main source of employment for the majority of the rural population and the bulk of the staple food is produced by this segment of the population.

The project was first conceived as a “Transnational project on the Management of Major Regional Aquifer in N.E. Africa” during the UNCOD held in Nairobi in 1977 and that it had been taken up by ADALCO in 1987. He pointed out that the sandstone aquifer occupying an area of about 2,000,0000 sq. km underlines the common border areas of Sudan, Egypt, Libya and Chad. Environmentally, it was observed that the zone has a relief characterized by a vast sandy plan, which is occasionally interrupted by scattered flat topped Nubaian plateaux and escarpments.

The population of African countries is likely to double over the next twenty years.

This is the real of challenge facing African countries at the close of this century.

This paper is a draft report on the Ad Hoc Committee on the Draft Medium Term Plan.

The main objective of the symposium was to assess the performance of Farming Systems Research (FSR) in the sub-region in terms of new knowledge generated, technical agricultural research results, research methods and techniques, multi-disciplinary practices, the participation of farmers and extension workers in the research process, and the degree of institutionalization of the approach itself. An additional objective of the symposium was to identify priority areas and themes for collaborative research projects and research funding requests in the sub-region.

This study assesses the economic implications of land ownership security in rural Thailand. It uses data from this country to rigorously analyze several aspects of land ownership security. It provides both qualitative and quantiative information on the effects of ownership security. The study presents a conceptual model and literature review and is followed by separate discussions on the evolution of land rights in Thailand; the study methodology and the nature of the data; and the credit market.
