Description

The GDA Water Resources consortium, in collaboration with the World Bank is using Earth Observation (EO) data to address water-related issues in Botswana. Botswana faces water scarcity due to its arid landscape, low rainfall and reliance on groundwater, which supplies about 80% of the countries water. To combat these issues GMV experts, as part of the Water Resources consortium, conduct long-term monthly assessments of groundwater status, complemented by a suite of EO-based products, including potential groundwater recharge estimates, groundwater resources assessments at national and catchment/regional scales, and comprehensive flood hazard assessments. In 2024, GMV will further extend its support to the World Bank by providing flood hotspot observations, ensuring a comprehensive understanding of Botswana’s water security landscape.

Key Takeaways

    • Earth Observation (EO) technologies are crucial for monitoring Botswana’s groundwater resources and managing flood risks, supporting the country’s efforts to combat severe water scarcity.
    • Botswana’s reliance on groundwater (80% of its water supply) is threatened by overexploitation and droughts, making EO-based assessments essential for sustainable water resource management.
    • The partnership with the World Bank and the GDA programme aims to reform Botswana’s water policy and integrate EO into national water security strategies, ensuring long-term water sustainability.
