Drought and Water Scarcity in Europe: past and future (Secheresse et déficit d’eau en Europe: passé et perspective)

Research output: Contribution to journalArticleAcademicpeer-review

Abstract

Low river flows and droughts are increasingly being observed over the last decades in Europe. Moreover, in vast areas drought will likely increase due to climate change? The increasing trends to more severe drought are explained in the context of growing water scarcity that also is reported in many European regions. Water scarcity often enhances drought impacts. First, trends in historic European drought events are discussed. Then understanding of transformation of meteorological drought into soil moisture and hydrological drought (groundwater, streamflow), which is called drought propagation, is described. Knowledge on drought propagation is essential for water resources management. Water scarcity in Europe and its spatial distribution is touched upon, incl. an observational-modelling framework that is being proposed to distinguish between water scarcity and drought. We conclude with an assessment of future drought and water scarcity due to global change and implication of the use of modeling chain approaches, incl. uncertainty.
