20世纪，埃塞俄比亚高地普遍存在着集资现象。它威胁着土壤资源，通过加强排水和干旱，降低了沟谷间地区的作物产量，并加剧了洪水和水库淤积。了解过去几十年中沟壑发展的年龄和速度将有助于解释目前土地退化的原因。
Gullying has been widespread in the Ethiopian Highlands during the 20th century. It threatens the soil resource, lowers crop yields in intergully areas through enhanced drainage and desiccation, and aggravates flooding and reservoir siltation. Knowing the age and rates of gully development during the last few decades will help explain the reasons for current land degradation.
