WATER SCARCITY OR DROUGHT? THE CAUSE AND SOLUTION FOR THE LACK OF WATER IN LAGUNA DE ACULEO

Abstract

One of the most recurring discussions among people is the real impact of global warming and human activity on our natural resources. It is hard to identify and quantify the impact generated by each one. Laguna de Aculeo located in Paine city, Chile. It was one of the most attractive and beautiful places to visit in the summer. Today, It has been completely drying up. This research evaluates weather and hydrologic values registered by government weather and water levels stations. The purpose is to evaluate if there has been a change in precipitation, temperature, and water level trend. The analysis consists of the evaluation of the statistical parameters, and legal water withdrawals and fines imposed. The results of this study indicate that the cause of the drought of the lake is generated by climatic and anthropogenic factors. However, the changes in precipitation and temperature over the years are not significant for drying a lake. Therefore, it is possible to assume that human activities are arguably the greatest cause of impact on Laguna de Aculeo. Finally, we present tools, strategies, and practical solutions to prevent, control, and restore lake water level.
