Drought in Europe: state of the research and challenges

Heure

10:30 - 11:30

Lieu de l'événement

WSL Birmensdorf

Drought not only affects semi-arid regions, like in Africa. Also Europe has experienced severe drought events over the past decade, for example in 2003, 2011, and 2015.

Trockenheit in Europa

In a collaborative effort started by the UNESCO FRIEND NE Europe Low Flow and Drought group and the European Drought Centre, researchers from around Europe have combined data and tools to characterise the impacts and the meteorological and hydrological drivers of the 2015 drought event and compare it to previous events like 2003. In absence of real-time groundwater data, we also tested methods based on precipitation and GRACE satellite data to characterise the groundwater drought situation for these events. A major challenge in characterising and managing hydrological drought in Europe is the large influence of anthropogenic activities, both alleviating and aggravating drought in river flow and groundwater. Under the umbrella of the international IAHS initiative Panta Rhei, the working group “Drought in the Anthropocene” is developing methods to quantify and understand the anthropogenic drivers of hydrological drought.
