Ethiopia is one of the countries facing serious ecological imbalances. During this century natural resource degradation has accelerated and a destructive cycle of land use has developed in parts of the country involving deforestation followed by continuous cropping and grazing with little or no investment in the soil. This provides few opportunities for the natural vegetation to regenerate, reduces the productivity of the soil leaving it susceptible to erosion, and affects the hydrological cycle thereby altering the regimes of the rivers. Drought is also a recurrent feature in the country and soil degradation has increased the impact of this problem upon crops.
