| Abstract |
Groundwater is the hidden foundation of the Upper Zambezi River Basin’s economy, supporting hydropower stability,
large-scale agriculture, and rural water security. However, data reveals a systemic decline in storage, with "hotspots" of depletion emerging in Western Zambia. Current ground-based monitoring is insu cient to manage this risk.
By integrating machine learning with satellite data, we can now monitor groundwater at a 5km local scale. This brief calls for the immediate institutionalization of these tools to prevent a "blind" water crisis and to secure the region’s climate-resilient future. |
