Abstract

Recharge sustains groundwater resources that are depended on globally for drinking water and irrigated agriculture. A newly compiled 55-year record of groundwater-level observations in an aquifer in central Tanzania reveals the highly episodic occurrence of recharge resulting from anomalously intense seasonal rainfall. Model projections show a shift towards more intense monthly rainfall, which favours groundwater recharge, suggesting it may be a viable adaptation water source in the future.
