Large-scale dams on the continent used for irrigation or flood control are reportedly coming up to a critical age. The Kariba Dam straddling Zimbabwe and Zambia is a key example, according to a new report by the UN University Institute for Water, Environment and Health. And while climate shocks could impact the dams, ageing is also a major concern. If the rain pattern changes it can affect erosion of a dam structure and even accelerate the deterioration process, because it brings more silt and sediment into the dam.
