I had written on this topic sometime ago. My present research on dams and malaria in Africa triggered me to invoke some more thoughts (http://www.malariajournal.com/content/14/1/339). Several dams are under construction in sub-Saharan Africa. According to FAO database, some 118 dams are currently under construction while several more are planned. My analysis indicated that over half (57%) of these dams are located in areas with unstable/seasonal malaria. Previous studies indicated that dams in unstable semi-arid areas intensify malaria transmission. Now the question is why malaria control is not considered why designing, planning and operating such water storages that have potential to increase malaria? Water management particularly reservoir management has previous been used in western world. This tool has never been used in Africa. WHY? Shall we just rely on bednets and IRS? Or do we need to consider additional vector control measures such as reservoir management? We need to discuss this matter as it is a pressing issue in sub-Saharan Africa.
