A recent study, delivered in July 2016, projected that by 2050 Santiago will have the most extreme variation in temperature of all regional capitals, with 2.7°C, which is 14% higher compared to today. In winter, the increase will be 1.7%, representing an increase of 19%, while precipitation will be reduced by 55 millimeters (mm), 15% less.

Water accounting is a fundamental basis to understand water availability and demands and the related benefits and efficiencies are related to water uses. While the fundamental data needed for establishing water accounts is often missing, Remote Sensing can contribute to fill the data gaps.
The Water-Energy-Food Security Nexus (WEF Nexus) is currently a highly important debate in environmental policy with expected implications for priorities in research, education and international cooperation. Increasing demands for water, energy and food together with external and internal change drivers on current natural resources use patterns make the Nexus idea crucial to understand the multiple resource use interlinkages.
