World Bank Water Data Revolution: Closing the Data GAP for Transboundary Water in Africa

This report details the Water Data Revolution (WDR) initiative launched by the World Bank in 2021 to address data gaps in transboundary water management across Africa. The program, supported by the Cooperation in International Waters in Africa (CIWA) program, focuses on leveraging remote sensing technology, capacity building, and tailored tools to enhance sustainable decision-making for shared water resources.

Key Challenges Addressed

• Water Stress: Africa’s growing population, expanding economies, and climate change exacerbate water scarcity, limiting agricultural productivity and threatening regional stability.
• Data Deficiencies: Inadequate water data collection networks and human capacity hinder effective transboundary water management.

Program Structure and Achievements

The WDR project is organized into three strategic pillars:

1. Pillar A: Assessed the data needs and capacities of African River Basin Organizations (RBOs), identifying gaps in data collection, analysis, and sharing. The assessment involved surveys and interviews, revealing key priorities for training and technical support.
2. Pillar B: Provided targeted online training and workshops on remote sensing tools (e.g., Google Earth Engine, WA+) to build capacity among RBO staff. Workshops focused on data management, visualization, and applications like water accounting and flood monitoring.
3. Pillar C: Developed Water Accounting (WA) dashboards for selected basins (Volta, Incomati, Maputo) using remote sensing data, facilitating open, real-time data access and collaborative decision-making.

Impact and Lessons

• The project has enhanced data accessibility, technical capacity, and regional collaboration.
• Successes emphasize the importance of leveraging free public data, cloud-based tools for real-time analytics, and user-driven capacity building.
• Insights highlight the need for adaptable tools and ongoing support to address varying RBO capacities across Africa.

Overall, the WDR project establishes a robust foundation for sustainable transboundary water management, promoting equitable resource use and climate resilience through improved data and technology.
