As most parts of the developing world, Ethiopia faces a fast growing population and the pressing need to increase agricultural production in order to be able to supply its people with sufficient and nutritious food. Land expansion is no option any more so that the focus lies on the intensification of production. While improved seeds and fertiliser are the traditional technologies of choice offered to the farmers by extension services, management practices like erosion prevention and conservation tillage have joined the circle of recommended innovations over the years. Numerous studies have tried to explain the mostly reluctant uptake by the smallholder farmers with results reaching from lack of information and access to all kinds of constraints, including lack of credit and insurance.
