hydrosolutions GmbH attended the annual SAWEL Reflection & Planning workshop, which took place last week (6. – 10.December 2021) in Bamako, Mali. The key objective of the SAWEL project is to improve food security in the Sahel Region in Africa through ecologically sustainable agricultural water management. Two of the focus regions of the project are in Mali: Lac Wégnia, a RAMSAR site located approximately 80 km north of the Malian capital Bamako, and the Sourou floodplain, a transboundary wetland at the border to Burkina Faso. We have investigated the causes of observed hydrological changes and use remote sensing to provide reliable data for decision-makers to develop sustainable abstraction scenarios, limits, and policies.
