Taller de expertos sobre métodos de evaluación de recursos hídricos y usos del agua en América Latina -
Information on water use is required for political, economic and academic decision making on issues affecting everyone?s life. Owing to fi nancial constraints, it is diffi cult to have complete and comprehensive information on everything related to water. Techniques and methodologies are, therefore, used to affordably maximize control. To improve understanding of the different techniques and methodologies used to generate information, the AQUASTAT team sent thematic questionnaires to approximately 170 countries in April 2009.
