At the 2017 CSI Meeting in Cali, Salman Siddiqui from IWMI presented a study mapping the correct location of large dams in Sub-Saharan Africa, in the context of studying their linkage with malaria epidemics. From a public database containing the location of 1,285 large dams across Sub-Saharan Africa, the team was able to confirm the correct location of 956 dams, after controlling the quality of location information.
Linking this information with observed malaria incidence data, overall, the study found a correlation between the location of large dams with the incidence of malaria and assessed that over one million people in sub-Saharan Africa will contract malaria this year because they live near a large dam. Further, it was estimated that the planned construction of an expected 78 major new dams in sub-Saharan Africa over the next few years will lead to an additional 56,000 malaria cases annually.
