Abstract

The arid and semi-arid regions occupy more than 45% of global land surface, including the central territory of Chile. The latter represents a region which should be preserved due to its economic, ecological and climatic values. Nonetheless, the increasing pressure on water and climate change suggest the quantification of its present and future water resources as well as to know what biomes could be affected by these hydrological variations. So, we have quantified the current and future water balances for whole Chile and investigated about the Mediterranean vegetation formations more affected by the variations in the water amount. The results have shown that the central part of the country, where inhabits the most of Chilean population, is the territory more sensitive to water scarcity since reductions in water can represent an average of 75 mm y-1 for 80% of the Mediterranean biome. This reduction could suppose these areas do not work properly any more.
