Abstract

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 socio‐economic 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.
