Climate change and deforestation threaten water supply in Kenyan town.
Water availability in Kenya's Kaptagat catchment is affected by land use changes and climate variability. Using the SWAT model, researchers found that increased settlement led to less forest cover and more intense rainfall events. This caused more surface runoff, less groundwater recharge, and fluctuating water levels in dams. Afforestation and terracing can help improve groundwater recharge and reduce surface runoff, stabilizing water levels over time.
