• Flood Control 2015: Global Flood Observatory

  European Commission, 2011-2012

  Remote sensing expert: a methodology to produce and disseminate near-real time global flood maps based on active radar (EnviSAT) data is developed. The feasibility to produce near real-time maps based on the new high resolution satellite mission “Sentinel” is piloted.

• FP7 DEWFORA: Improved Drought Early Warning and Forecasting to strengthen preparedness and adaptation to droughts in Africa (2011-2013, European Commission)

  EU, 2011-2012

  Hydrologist and forecasting expert: In this project, a new framework to establish drought early warning systems and procedures in Africa is developed and piloted in a number of catchments across Africa.
