西部非洲水电潜力约为24 000 MW,但目前仅开发10%,且灌溉率约为12%。经济落后造成该地区丰富的水资源处于未开发状态,国际水资源管理研究所(IWMI)将该地区定义为经济性水资源短缺地区,目前西非正在准备修建大量大坝。然而,有些大坝项目经历了漫长的等待,有的甚至长达50 a。为说明这些项目的现状,2009年,西非国家经济共同体发起了“西非大型水利设施对话”的倡议,旨在盘活一些现有水利项目。介绍了该倡议的背景及实施状况。
The hydropower potential in Western Africa is about 24 000 MW but currently only 10% is developed and the irrigation rate is about 12%. Underdeveloped economies have caused the area’s vast water resources to be undeveloped, with the IWMI defining the area as an economically water-scarce area, and a large number of dams are currently being prepared in West Africa. However, some dam projects have experienced a long wait, sometimes as long as 50 years. To illustrate the status of these projects, in 2009 the Economic Community of West African States initiated the “Dialogue on Large-scale West-West Irrigation Facilities in West Africa” to revitalize some existing water projects. The background and status of the initiative are introduced.
