The global livestock sector is diverse, undergoing rapid change and frequently

misunderstood. Livestock impact issues of major global concern, including food security,

poverty alleviation and environmental and human health. But these impacts differ greatly

across the globe, depending on factors such as the levels of wealth or poverty in a

country/region, the livestock commodity, consumer demands, the policy environment and

the livestock production system. This paper explores global trends in the livestock sector in

Recommendations for preservation and improvement of sub-Saharan rangelands, and for training people in range management and animal production.

The integration of crops and livestock has often been cited as a model for agricultural development in semi-arid West Africa. Recent formulations treat the adoption of more intensive forms of manuring as a critical step in agricultural development. These analyses have been criticised for ignoring or underestimating the possible negative consequences of such management on rangeland and livestock productivity. This paper critically examines this debate. It is argued that the agronomic benefits of manuring depend largely on nutrient transfers from non-cropped grazing lands.

Research was done in the upper part of the Genale River basin in the Sidama Zone, Ethiopia. The research focussed on answering the question whether coffee-based agroforestry could ve an impact on the local hydrology. Discharge data, land use data and soil data was collected in the field and from literature and together put into a SWAT model to investigate the hydrological cycle of the basin. Several scenarios were created in which the amount of coffee in the area was altered.

There is an urgent need for new approaches and effective models for managing risk and promoting sustainable development in arid and semi-arid lands (ASALs), especially in the face of climate change and increasing frequency of drought in many areas. This study assesses the impacts of the Arid Lands Resource Management Project (ALRMPII), a community-based drought management initiative implemented in 28 arid and semi-arid districts in Kenya from 2003 to 2010.

These are the Proceedings of the last joint workshop of the Pasture Network for Eastern and Southern Africa (PANESA) and the African Research Network for Agricultural Byproducts (ARNAB), held in Gaborone, Botswana, 4-8 March 1991. This volume contains the three addresses delivered at the opening session together with 38 full texts and 12 abstracts of papers presented at the workshop. The scientific papers are grouped in three sections, corresponding to the main themes of the workshop.
