Particularly in tropical and subtropical Africa, soils are affected by degradation, which has a negative impact on agricultural production. The arable and pasture land of the Ethiopian highlands form the basis for the livelihood of a large part of the population, though being one of the most degraded areas in the world. More efforts must therefore be made to stop the progressive soil degradation and, where possible, to reverse it.en-USsocio-economic scenariosEthiopiaClimate smart biochar systemsbiomass resource assessmentsoil fertility improvementreport
