By Katy Migiro NAIROBI (Thomson Reuters Foundation) – One million Africans will catch malaria this year because they live near a large dam and, at a time of booming dam construction on the continent, greater efforts must be made to protect people from the killer disease, a study said on Friday. Almost 80 major new dams are due to be built in sub-Saharan Africa over the next few years, leading to an additional 56,000 malaria cases a year, the study in Malaria Journal predicted. “While dams clearly bring many benefits — contributing to economic growth, poverty alleviation and food security — adverse malaria impacts need to be addressed or they will undermine the sustainability of Africa’s drive for development,” the paper's lead author, Solomon Kibret of Australia's University of New England, said in a statement.
