Climate change threatens to double malaria risk from African dams, say researchers

By Magdalena Mis LONDON (Thomson Reuters Foundation) – The number of Africans at risk of malaria who live near dams will nearly double to 25 million by 2080 as areas where the disease is not currently present will become transmission zones due to climate change, researchers said on Monday. Without prevention measures, the number of malaria cases associated with dams could triple to nearly 3 million a year over the same period, they said in a study published in Malaria Journal. “While dams clearly bring many benefits … the role of climate change on malaria around dams will fundamentally alter the current impact,” said Solomon Kibret of the University of California and the paper's lead author.

One million Africans a year catch malaria from dam mosquitoes: study

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.
