Mapping Aquifers for Climate Adaptation and Resilience in Zambia

Zambia is facing a growing water crisis, one that is being intensified by the effects of climate change. Rainfall patterns are shifting, and in drought-prone regions, water bodies such as streams, rivers, and lakes are drying up. This crisis is deeply affecting millions of lives and livelihoods across the country. Women and children are increasingly burdened with walking longer distances to access clean and safe water, while farmers struggle with declining crop yields and the uncertainty of changing seasons.

In this increasingly precarious context, groundwater resources—such as springs, wells, and aquifers—have become more vital than ever. Although often overlooked due to their hidden nature, groundwater represents nearly a third of the world’s freshwater supply. It serves as a critical buffer during periods of drought and functions as a reliable reserve during times of water surplus. In Zambia, it holds immense potential for supporting climate change adaptation and strengthening food and water security.
