在过去的三十年里，尼日利亚出现了前所未有的水坝建设热潮，为全年供水、灌溉和渔业蓄水。在文献中确定的323个大坝中，246个（76.2%）是自1970年以来建造的。虽然只有47个水库湖泊进行了调查，以寻找蜗牛中间宿主，47个湖泊中有11个进行了人类感染调查，但各工作人员获得的结果非常有启发性。47个湖泊中有20个（42.6%）发现血吸虫病螺宿主，11个湖泊中有10个（90.9%）发现人感染。这些研究结果表明，水坝建设正在助长尼日利亚的血吸虫病传播，除非采取紧急措施扭转这一局面，否则水坝对健康的不利影响将超过其社会经济效益。本文讨论了这些问题的背景下，现有的体制和法律的框架在尼日利亚，并确定适当的措施，可以实现可持续的水资源开发在未来。
In the last three decades, there has been an unprecedented upsurge in dam construction in Nigeria to store water for year-round water supply, irrigation and fisheries. Out of a total of 323 dams identified in the literature, 246 (76.2%) were constructed since 1970. Although only 47 of the reservoir lakes have been surveyed for snail intermediate hosts and 11 of the 47 for human infection, the results obtained by the various workers are very revealing. Snail hosts of schistosomiasis were found in 20 (42.6%) of the 47 lakes and human infection in 10 (90.9%) of the 11 lakes investigated for the respective purposes. These findings show that dam construction is contributing to schistosomiasis transmission in Nigeria and, unless urgent steps are taken to reverse the situation, the adverse health consequences of the dams will more than balance their socioeconomic benefits. This paper discusses these problems in the context of existing institutional and legal frameworks in Nigeria and identifies appropriate measures, that could achieve sustainable water resources development in the future.
