Monitoring and managing water resources, particularly in arid and semi-arid regions, are crucial for the wellbeing of communities. Africa, as the most vulnerable continent to the adverse impacts of climate change, faces challenges such as changing rainfall patterns, increased frequency of extreme weather events, and floods. This free webinar, open to all, discussed the benefits of hydrological products for Africa and how to best access satellite-based hydrological data.

Hydrological data play a vital role in monitoring and managing water resources. They help governmental agencies to manage the use of water resources, to mitigate water-related disasters, to improve goods transportation in rivers, as well as to plan for climate adaptation. They also support growth in various economic sectors that are dependent on weather and hydrology, for example by helping farmers to increase crop yields and by enabling people to safely evacuate risky areas before a flood hit.

However, there is a lack of ground observation data and early warning coverage in Africa.  Space-based observations from satellites, such as precipitation estimates, soil moisture, evapotranspiration, and river level information, have the potential to improve the monitoring of hydrological parameters, and are crucial for sustainable water resource management, flood forecast and climate adaptation.

EUMETSAT is committed to supporting data users in Africa with products covering the entire African continent. EUMETSAT provides operational products for hydrology, notably through its Satellite Application Facilities (e.g. the SAF Support to Operational Hydrology and Water Management (H SAF), and Land Surface Analysis SAF).
