摘要
本文介绍了墨西哥城大都市区(MCMA)现状的概况。分析指出,迫切需要彻底改进现行的供水和污水管理的做法,以使之能够可持续发展。MCMA是全世界增长速度最快的城市中心之一,人口约为2100万,移民的比率非常高,有大量的非法定居者。为了能够满足日益增长的用水需要,历届政府几乎都把全部注意力放在供水管理和工程措施上,因而投资了数亿美元,建设大型的基础设施工程以实现跨流域调水。与水资源管理有关的环境、经济和社会政策大多是不充分、不适当的,结果导致生活在世界上最大的城市聚集区之一的人口的环境、健康和社会经济状况正在不断恶化。但是,令人感到奇怪的是,到目前为止,还没有规划出关于需求管理、再利用、环境保护以及改进水资源管理做法的长期战略。
The paper presents an overview of the present situation of the Mexico City Metropolitan Area (MCMA). The analysis indicates an urgent need to radically improve the current water supply and wastewater management practices, to become sustainable. The MCMA is one of the most rapidly growing urban centers of the world, with a population of about 21 million people, a very high rate of immigration and numerous illegal settlements. In order to meet the increasing water demand, successive governments have focused almost exclusively on supply management and engineering solutions, which have resulted in investments of hundreds of millions of USD and the construction of major infrastructure projects for interbasin water transfer. Environmental, economic and social policies associated with water management are mostly inadequate and insufficient, which is resulting in increasing deterioration in the environment, health and socioeconomic conditions of a population living in one of the largest urban agglo-merations of the world. Surprisingly, however, no long-term strategies on demand-management, reuse, conservation, and improved water-management practices have been developed so far.
