水不足
Water stress or water lack, poses the greatest threat in Spain. Water scarcity is a significant issue in many regions throughout Spain and climate change may aggravate the problem, with longer periods of dry weather. Supply problems regularly occur in the Jucar basin during summer. In the Segura basin, water scarcity has resulted in an increase of the water prices by 30% for households. Overall, the regions in the south-east of Spain are particularly vulnerable to water shortages. Furthermore, large areas of the Mediterranean are affected by saltwater intrusion.
