The EO4SD project is delivering EO-products to support Zambezi River Basin Management project (ZRBMP) funded by the World Bank.
A key objective of ZRBMP is to strengthen the role of the Zambezi Watercourse Commission (ZAMCOM) in promoting joint management and development within the Zambezi River Basin through improved information sharing and decision support and strategic planning.
Surface water plays a very important role in water supply across the Basin. Many rivers, streams and lakes/reservoirs provide water for domestic usage as well as being used in irrigation, for livestock watering and as a source for hydropower and recreation. Still, in most of the Zambezi countries, government’s measurement of water resources is limited to major dam resources and river flow stations. This however represents only a small portion of the overall water resources with substantial portions of water being stored in e.g. privately held infrastructure such as farm dams. The unmonitored proportion of water resources represents a major known unknown, which can produce huge inaccuracies in water resource assessments and can represent a great risk to water users dependent on those resources.
Assessing the amount of small and large-scale water resources using Earth Observation data is therefore seen as an essential tool for efficient planning and decision making for the current and future utilization potential of the land. Monitoring water bodies for a whole country or river basin in a comprehensive manner is essential for the national water resources management in respect to drought mitigation, irrigation management and planning of infrastructure investment (e.g. dam constructions).
In this page we demonstrate how EO can be used to provide regular monitoring information on surface water resources in the Kariba/Tete sub catchments of Zimbabwe which is a region with a particular high density of small reservoirs and dams within the Zambezi basin.
