Water management agencies in many parts of the world are currently missing big opportunities to increase their capacity to monitor water resources. This report presents a range of remote sensing applications to support water resources management and decision-making, and discusses implementation approaches and their sustainability going forward. These were developed within the second phase of the global initiative on remote sensing for water resources management, conceived to help mainstream beneficial remote sensing uses in operational projects of the Bank, and to facilitate the adoption in World Bank client countries. This report is addressed to water practitioners in general, technical staff in national water agencies, and project leads from development and financing institutions. The goal of the report is to present insights from innovative remote sensing applications to help address specific water resources management challenges. The results presented include constraints identified in the adoption of remote sensing, the approaches adopted to make applications functional in different contexts, the project applications themselves, insights on their sustainability, and ways forward.
