The impacts of climate change are expected to be generally detrimental for agriculture in many parts of Africa. Overall, warming and drying may reduce crop yields by 10–20% to 2050, but there are places where losses are likely to be much more severe. Increasing frequencies of heat stress, drought...

Describes modifications to the traditional ox-drawn ard plow (maresha) for use in the construction of terraces for soil conservation and of raised beds and furrows to facilitate drainage on heavy clay soils together with results of on-station and on-farm tests. Both modifications can be made by v...

In developing country production environment, farm production efficiency is often measured in terms of on-farm resources and producer characteristics. In this paper we postulate that input and output market related factors also influence farm production decisions hence its efficiency. Stochastic ...
