This document first describes the main agroecological zone found in sub-Saharan Africa and the environmental constraints to agricultural production inherent in these zones. This is followed by a description of the main agricultural production systems and land use practices. Factors that have cont...

Economic factors and policies encouraging environmentally detrimental land use practices in sub-Saharan Africa
In semi-arid south-western Niger, climatic variability, low productivity, poverty and institutional constraints limit the scope of agricultural production to meet the rising needs of the growing human population. The integration of crop and livestock production activities has long been seen as th...

Options for intensification of mixed crop-livestock systems in rural communities of south-western Niger: Prospects and constraints
Intensification of land-use is inevitable for long term food security in the east African highlands, but technological options need to be environmentally safe. How forages can be used as a basis for intensified grain and fodder production from the same land unit, and serve as a profitable fallow ...

Night corralling of livestock directly in crop fields during the dry season contributes to nutrient cycling for the benefit of crops. Rangeland grazing and corralling livestock on selected croplands result in a spatial transfer of organic matter and nutrients from rangelands to the corralling sit...

Metabolizable energy (ME) and crude protein (CP) of the stall-fed resources met half of the requirements of crossbred cows in the Central Ethiopian highlands. The average supply of ME and CP from stall-feeding supported a milk yield of 850 kg or 55 percent of the lactation yield. The additional M...

A survey was conducted on 224 randomly selected farmers, comprising those participating and non-participating in a goat corssbreeding project in Burundi, and 54 farmers chosen as `breeders' by the project. Participating farmers were similar to the average goat farmers in the region in terms of la...
