The moist savannah zone in sub-Saharan Africa is regarded as a high potential area for crop and livestock production. Currently, human labour is the principal source of power for crop production and the level of commercial energy use is very low. Agropastoralism and pastoralism are the principal ...

Energy and the evolution of farming systems. The potential of mixed farming in the moist savannah of sub-Saharan Africa
The incorporation of livestock into alley farming systems, in which food or forage crops are grown between hedges of multipurpose trees that are regularly pruned for mulch and/or forage, has been studied for over 10 years in Africa. Prunings from leguminous trees such as Leucaena and gliricidia c...
In Ethiopia smallholder livestock producers have adopted components of improved dairy technologies but the intensity of adoption remains low. It is hypothesized that credit-related constraints limit the ability of many smallholder farmers to make investments in crossbred cows and/or to purchase c...

Land degradation is one of the major problems related to low productivity in Ethiopia. Vertisols are potential agricultural lands but are underutilized due to waterlogging during the rainy season and are prone to soil erosion due to the traditional practices of planting crops at the end of the ra...
