Discusses the results of the measurement of environmental changes in grazed ecosystems with reference to correlated changes in livestock management in Kenya; includes techniques used to measure the changes, and proposed methods; presents data on a case study at a group ranch located in western Kenya which covers 50,000 ha.; ends with comparison of surveys, i.e., that of 1978 and 1981.

Potential of tropical Africa for agro-industrial by-products suitable for animal feeding and fattening w. data on feed value of byproducts from cereals, tubers, oilseeds, sugar canes and others.

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.

This study was conducted to characterize the traditional milk production and marketing system, and to identify constraints and opportunities for further development. It was conducted in Mieso District of Oromia Regional State, located 300 km east of Addis Ababa and at about 200 km east of Adama. Five rural kebeles, Dire Kalu, Gena, Huse Mendera, Hunde Misoma and Welda Jejeba, that have milk production potential were selected. Farmers/agro-pastoralists from each rural kebele were also selected.

This sourcebook, and accompanying poster learning series, is aimed at policy makers, planners in government, local research administrators, civil society partners and researchers in Southeast Asia. Compiled and repackaged by Dr. Julian Gonsalves and a resource team, the Climate-Smart Agriculture (CSA) source book draws from a rich pool of literature from over 700 sources. The compilation provides succinct, relevant and timely information about climate challenges, and potential solutions from previously published work in a simplified or a shortened form from around the world.

This study aimed to evaluate the impact of climate change on the geographical distribution of selected native species from two areas from West Asia and North Africa. Three species representing two genera were selected for assessment of their vulnerability to climate change. The first species was Salsola vermiculata L. which is common to both study areas. The second genus was represented by two species, Haloxylon salicornicum (Moq.) Bunge from the Syrian rangelands and H. schmittianum Pomel from southern Tunisia.

Sustainable development of pastoral and agro-pastoral systems, dominated by collective and/or tribal ownership of rangelands, is a key issue for the West Asia and North Africa region. These two systems are located in arid and semi-arid areas and are increasingly threatened by desertification process. The policy responses to tackle this complexity have been a sectorial and fragmented, “top-down” approach, putting forward technical solutions and neglecting the social context.

This workshop was conceived in recognition of the fact that, over the years, a great deal of research has been conducted on trypanotolerance. With the advent of new and powerful means to identify markers and genes controlling traits of interest, and with the developments in animal breeding bringing greater speed in dissemination of desirable genotypes, there is increasing interest in trypanotolerance as a way forward in trypanosomiasis control.
