This chapter sets out the challenges facing coastal countries in Western and Eastern Africa in managing their coastal and
marine resources for the sustainable benefit of their populations, in the context of the increasing ...
Soil activity in engineering terms is applied to the ratio between the plasticity index and clay content and reflects the type of clay mineral dominant in the soil. It is related to the specific surface area/charge resulting ...
Impacts of changes in the Lake Victoria fishery on food security (FS) are analysed, focusing on the role that fish and the fish industry play in FS for local communities and national food policy goals. Food has become less ...
Agriculture in over 84% of world farmlands is rainfed but yields just over half of the crops produced. In East Africa 60% of the landmass is arid and semi-arid land (ASAL), where rainfall is inadequate for arable agriculture. ...
