快速增长的人口需要更多的生产食品、饲料、纤维和燃料从土地。Highlands of Ethiopia, with altitude above 1500 Meters Above Sea Level (MASL) are the dominant sources of water, crop and fodder production. They are densely populated and hold about 90% human and about two-thirds of livestock population. The highlands cover about 50% of the land area with 95% of the cropping land会计超过90%的国家的经济。为了满足这些需求,把大片的土地集约种植和大面积的草原过度放牧和退化在埃塞俄比亚。此外,新的和边际土地往往被投入生产。土地资源是有限的,不可再生和容易退化通过滥用和管理不善[1]。在埃塞俄比亚,自然资源面临巨大的压力。土地退化,包括森林砍伐,水土流失和土壤生物退化的报道非常猖獗的全国各地[2]。报道称,由于它的自然地形,移除土地覆盖导致土壤退化。Environmental degradation, high population growth in developing countries, and the need to enhance sustainable agricultural productivity are interlocked issues that constitute a triple global challenge currently. For combating and minimizing the rate of soil degradation and to improve the land productivity through sustainable use of soil resources, understanding the soil physicochemical characteristics of land use systems and管理实践是必需的。此外,了解土地利用类型的影响和保护实践土壤特性开发土地有用吗管理战略和可持续农业[3]。
