Kenya's hydropower dams fuel malaria risk for villagers

A lfred Nyaga irrigates his acre of khat, a mild stimulant, in Kaloki village by pumping water with a diesel-powered engine directly from Kamburu Dam in central Kenya.

Each morning, he takes the khat he has harvested at night to sell at Kiritiri market, some 30 km (18.64 miles) from the village on a shrub-covered slope stretching to the hydropower dam's banks.
