The literature on technology adoption distinguishes between diffusion (generally viewed as a dynamic process) and adoption (usually seen as static and specific to a point in time). Consistent with this, empirical studies on agricultural technology adoption generally divide a population into adopt...

The problem of seasonal shortages of herbage production from natural pastures in the Ethiopian highlands was investigated. This was done by comparing the available biomass amounts on the pastures with biomass amounts required for livestock grazing and for protecting land slope from soil erosion w...

Animal traction has been an integral part of most agricultural systems in Ethiopia for thousands of years. There is evidence that cattle were first used for ploughing in the latter part of the third millennium BC (Goe and Astatke, 1989). Today, the traditional cattle economy is directed mainly to...

This chapter discusses the traditional tillage implement and the alternative tillage implements using animal power in Vertisol management. Among the topics of discussion are land shaping equipment; the ridge and furrow system; minimum tillage with BBM attachments; animal drawn scoops; pond excava...

Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...
