Areas and situations for the study of water sustainability

The Social Sciences have contributed to the study of Sustainable Development from economic analysis, political, social, psychological and media on the consumption of natural resources in reference to their availability, extraction, and distribution, supply and recycling. In this sense, the objective of this work is to outline eight areas for the analysis of water issues. The relationship between availability and consumption of water belonging to the public supply network is described to establish a system of water tariffs set to situational water areas. In the case of water consumption rates, they seem to be due to public policies "clientelistic" that make it unfair charging system, subsidies, penalties, trading and transparency. The prevalence of clientelist system encourages water and increases the problems of conflicts between citizens and government through neighborhood networks against administrative authorities. In the future, the trend of availability and water consumption seems to outline a situation of extreme scarcity in which conflicts over water supply will be an indicator to explain economic crisis, political, social and individual. The discussions of water issues that prevent humanity develop sustainably contribute in building a public agenda water.
