    Soil erosion and deposition values were estimated using pixel based landscape information and the Unit Stream Power Erosion Deposition (USPED) model, which works with the Universal Soil Loss Equation (USLE) parameters. The USPED model was adapted to Ethiopian conditions based on evidence from the Soil Conservation Research Programme, and calibrated and validated using data from former research stations as well as the Abbay (Blue Nile) Basin. Additionally, some of the USLE parameters were reduced in order to achieve a satisfactory approximation of sediment loss for the Abbay Basin.

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    Ethiopia

    It soon became apparent that soil degradation in the Ethiopian Highlands may be posing a threat not only in terms of the physical loss of soils, but also in terms of deteriorating, soil chemical fertility. This study has therefore emphasized both the physical and chemical deterioration of soils due to degradation.

    Ethiopia

    Land degradation through extensification of agriculture and overgrazing is an increasing problem across large expanses of the Ethiopian highlands that give rise to a loss in a range of ecosystem services. Ecological restoration through exclosure establishment has become increasingly important approach to reversing degraded ecosystems in Ethiopia and particularly in the Amhara regional state, northern Ethiopia.

    Ethiopia, Africa, Eastern Africa

    Extensive land degradation in the Ethiopian Highlands jeopardizes rural livelihood. Intensified by increasing population pressure, farmers are forced to expand their arable land by deforestation and thus worsening the soil erosion problem. Through the application of various soil conservation measures, farmers and authorities try to prevent against further land degradation.
