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.

A number of studies have suggested that addressing greenhouse gas (GHG) emissions from agricultural

production, or ‘supply-side emissions’, will be insufficient to reduce agri-food sector GHG emissions to limit

the increase of global temperatures to well below 2o

C. Recent studies have also suggested that ‘demandside

measures’ related to food consumption, food value chains, and food loss and waste, will be necessary

to reduce emissions and may have a larger technical mitigation potential than supply-side measures.

During the past 70 years, concerted efforts by the national veterinary services of affected countries from Senegal to China and Russia to South Africa—aided by international organizations—have brought the once-dreaded rinderpest virus to the point of extinction. In the near future, we can expect to see a global declaration of freedom from rinderpest, the first time this has been achieved for a livestock disease. The devastation wrought by rinderpest stimulated the founding of veterinary schools in many countries, and provided the basis for the development of the veterinary profession.

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.
