Water shortage impacts hydrologic assets, platforms connectivity, biodiversity, water caliber, and river atmosphere functioning. It has direct affects on financial sectors that use and rely on water, resembling agriculture, tourism, undefined, power and delivery. The Mediterranean Basin is without doubt one of the areas on the planet so much at risk of weather adjustments, in addition to essentially the most impacted via human water call for. This quantity presents an in-depth view of the water caliber and volume implications of water shortage. It highlights its attainable explanations and describes the consequences in areas lower than Mediterranean weather. the subjects coated contain weather results, water assets (use, garage and new sources), water caliber (chemical and microbiological), and the consequences on ecosystems being affected by water shortage. This publication is addressed to scientists and scholars, but additionally to managers desirous about the mandatory choice making strategy to stand destiny classes of drought.

34 1 Water Scarcity, Water Stress and Drought, Expressions of Change in River Ecosystems In most of the world’s watercourses, dramatic modifications have occurred as a consequence of their intensive use by human societies [1]. Pollution, water abstraction, riparian simplification, bank alteration, straightening of watercourses, dam construction, and species introduction are widespread perturbations in river ecosystems.

2. The northern part of the Peninsula exhibits an Atlantic climate with sufficient water supply; the use of water accounts for 4–7% of the total resource available, though this does not prevent severe local shortages in large cities. However, demands increase to 30–80% of the total resource in the remaining catchments of the Peninsula, following the gradient of decreasing precipitation from NW to SE. In the Segura basin, located in the SE corner of the Iberian Peninsula, current demands exceed the supply by 224%, which requires an interbasin transfer of water (especially from the Tajo River).
