我们分析了土地利用土地覆被变化的幅度，并确定了这些变化的驱动因素在阿瓦什国家公园，埃塞俄比亚，使用航空照片，卫星图像和实地观察。野生动物最重要的栖息地--分散的荒地急剧减少。在研究期间，草地、农田或开阔地的面积增加。政策和公园边界划分问题被确定为1995年之前（权力下放之前）的变化驱动力，而牲畜放牧被认为是1995年之后变化的主要驱动力。主要事件和原因在很大程度上解释了这些变化，包括Ittu社区的移民，土地保有制度，干旱，偷猎，使用政策问题以及区域经济和基础设施发展。我们的研究表明，公园的可持续性要求立即采取行动，以减少不断增加的人类和牲畜对公园资源的压力。
We analyzed the magnitude of land use land cover changes and identified drivers of those changes at Awash National Park, Ethiopia, using aerial photographs, satellite images and field observation. Scattered bushland—the most important habitat for the wild animals, declined drastically. Areas under grassland, farmland or open land increased over the study period. Policy and park border demarcation issues were identified as drivers of change before 1995 (before decentralization), whereas livestock grazing was indicated to be the leading driver of change after 1995. Major events and causes that largely explained these changes include immigration of the Ittu community, land tenure system, drought, poaching, use policy issues and regional economic and infrastructural development. Our study reveals that the sustainability of the park calls for an immediate action to reduce the ever increasing human and livestock pressure on park resources.
