| 摘 要： | 介绍了非洲东部和南部雨水管网系统中雨水回用的实践与经验,并介绍了在Sub-Saharan Africa开展的雨水回用工程实践情况,包括国家政策的调研、回用理念的构建、雨水系统的建设和回用技术的评估.雨水回用技术在非洲东南部地区被大力推广,并被普遍接受,应用于生活用水及农业用水的补充以及环境可持续发展建设的各个方面.截止目前,已有12个国家级的雨水回用机构建成,他们为雨水回用系统的建设提供整体规划和技术指导.政府和投资商也逐渐转变态度,为推进雨水回用技术在经济、制度和技术上提供了优惠政策.合理的土地与水体管理是雨水资源利用最大化的关键.除了政策和制度的协调外,还需要充足的预算支持来推动技术的广泛应用.

| Abstract: | This paper shares experiences of the southern and eastern Africa rainwater network on rainwater harvesting.It also shares the lessons drawn from policy research awareness creation and networking building of national networks and assessment of promising water harvesting techniques in the Sub-Saharan Africa.The concerted promotional effort of the southern and eastern Africa rainwater network has resulted in the general acceptance of rainwater harvesting as a viable option for boosting domestic water supply agricultural production and environmental sustainability.To date twelve nationally registered rainwater harvesting associations have been established which are providing leadership and capacity building in rainwater harvesting.Governments and donors are also aligning their policies towards providing increased financial institutional and technical support for upscaling rainwater-harvesting techniques. This paper concludes that diligent land and water management is necessary for yielding the highest benefits from rainwater.In addition to enabling policies and institutions there must be ample budgetary support to increase adoption of the technology. |
