    The Kelka forest in the Mopti region of Mali is important for the provision of ecosystem services like carbon sequestration and maintenance of the hydrological cycle. The Kelka forest area occupies more than 300, 000 hectares with 15
    villages within and around its boundaries. The forest resources and soil fertility of the forest are in continuous decline due to a combination of climatic and human induced factors. For example, the availability of firewood has halved

    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.

    Despite numerous studies on townships, research into township economies and related commercial real estate markets is limited. The majority of studies refer to the economy only as part of a broader discussion about other themes such as housing. And, while the information in these studies is useful, it is not captured and discussed within an overarching conceptual framework, which would allow the relationships and causal factors that shape and drive such economies to be understood.

    Ever since the oil, financial and food crises of 2008, sub-Saharan Africa has witnessed a marked increase in large-scale investment in agricultural land. The drivers of this investment are varied and include growing food, water and energy insecurity as well as social and economic interests of investors and recipient countries. The shape of these investments and their eventual outcomes are equally influenced by the existing land and water governance systems in the host countries.

    Although there has been a considerable effort to reduce soil erosion and improve land productivity in Ethiopia, farmers’ investments in SWC remain limited. There is a long and rich tradition of empirical research that seeks to identify the determinants that affect farmers’ investments in SWC practices. Nevertheless, the results regarding these determinants have been inconsistent and scattered. Moreover, the impacts of different SWC practices have not been reviewed and synthesized.
