Impacts Water

Chile is endowed with abundant water resources with 1,251 rivers, 101 watersheds, and 15,000 lakes and ponds. The country has an annual per capita water availability of 53,000m3/year. However, water availability varies regionally with ranges from 52m3/year to 2.9 million m3/year (Chile Water Strategy 2012-2025). The agricultural sector uses most water resources (approximately 73% of extracted water) followed by industry (12%), mining (9%), and sanitation (6%) (Chile Water Strategy 2012-2025). Chile uses water resources to produce renewable energy, with a hydroelectric energy potential of 9GW/h. Water is a strategic input to productive sectors of the Chilean economy that support a significant percentage of GDP and employment. Historical trends point to challenges of water distribution and availability between regions, which may become more pronounced with a changing climate. Drought and water scarcity are projected to be concentrated in the central and northern regions compared to southern regions. Ensemble projection models estimate that annual severe drought likelihood for the country will increase by 34% (7-69%) by mid-century and 63% (27-84%) by the end of the century.
