In recent years, there seems to have a boost in construction of large dams and irrigation schemes in sub-saharan Africa, mainly in Ethiopia. With recognition of such infrastructures to ensure economic development and allevate poverty, Ethiopia is building large dams and constructing large irrigation schemes in parts of the countries where malaria is endemic. However, such water infrastructures have been shown to intensify malaria transsmission in communities living close to water storages. Hence, we need to devise tools to mitigate malaria transmission and breeding of mosquito vectors around water impoundments.
For large dams, reservoir management have been widely accepted to creat condition unsuitable to malaria mosquito breeding. Faster drawdawn of reservoir water levels has been associated with lower larval mosquito abundance at the shoreline of the reservoir.
For irrigation schemes, canal water management options could potential mitigate malaria transmission by affecting larval mosquito develompent in irrigated fields.
