A methodology accounting for the basin specific conditions is developed to assess the current and future water stress state of this region. The medium-term evolution of water stress is investigated using climatic scenarios and a water-use scenario based on efficiency improvements following the recommendations of the Mediterranean Strategy for Sustainable Development. Currently, the southern and eastern rims are experiencing high to severe water stress. By the 2050 horizon, a 30-50% decline in freshwater resources is simulated over most of the Mediterranean basin. While total water withdrawals would stabilize, or even decrease (10-40%), in several northern catchments, they would double in southern and eastern catchments. These changes should significantly increase water stress over the Mediterranean basin and exacerbate the disparities between rims. specialized Regional assessment Water stress index Climate scenarios Water-use scenario Sustainable development strategies Mediterranean basin Étude régionale Indice de stress hydrique Scénarios climatiques Scénario d_usage de l_eau Stratégies de développement durable Bassin méditerranéen ZONE MEDITERRANEENNE 062 021 344 9 432-440 2012 1631-0713 https://www.documentation.ird.fr/hor/fdi:010057359 10.1016/j.crte.2012.07.006 1631-0713 [F B010057359] https://www.documentation.ird.fr/hor/fdi:010057359 https://www.documentation.ird.fr/intranet/publi/2012/12/010057359.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-01-09 2017-08-23 fdi:010057359 fre
