 The Mara River Basin of East Africa is a valuable natural and cultural landscape that faces significant threats from climate change and land use change. Climate change projections suggest that the basin will experience decreased dry season flows and increased peak flows, resulting in more frequent water shortages and increased soil erosion. To mitigate these effects, the basin's water resource managers should focus on preserving its headwater forests and improving land management practices that promote infiltration and aquifer recharge.
