Mapping Large Dams and Malaria in Sub-Saharan Africa

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.

Quality-controlled, confirmed location of 956 large dams across Sub-Saharan Africa

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.
