The Use of Non-Conventional Water Resources as a Means of Adaptation to Drought and Climate Change in Semi-Arid Regions: South-Eastern Spain

subject

description

Drought is a climatic risk with notable repercussions on water supply systems. The aim of this study is to analyze the principal measures for management and planning implemented during recent decades in south-eastern Spain (Segura River Basin) to respond to drought situations, focusing on the role played by non-conventional water resources (desalination and treated water). The results demonstrate that the study area (despite being one of the driest places of Spain) is less vulnerable to drought than regions with an Atlantic climate and greater availability of water. This has been possible thanks to the integration of non-conventional water resources as a means of adaptation to confront this natural risk, which is estimated to become more intense and frequent in the future owing to climate change. The results presented in this article are part of the research project “Uses and Management of Non-Conventional Water Resources on the Coast of Valencia and Murcia as an Adaptation Strategy to Drought”, funded by the Spanish MINECO under grant number CSO2015-65182-C2-2-P and the research group “Landscapes and Natural Resources in Spain” (Regional Geographic Analysis and Physical Geography Department, University of Alicante, Spain).
