The GGRETA Project
In recent decades the use of groundwater has been increasing around the world in response to the rising demands for drinking water supplies and food production for a growing global population.
The lack of informed management of groundwater resources has led in many places to an overexploitation of local and regional aquifers. A comprehensive understanding of the resources, in particular in the case of transboundary aquifers, is the basis for science-based and informed decision-making and planning. The GGRETA Project addresses issues related to Transboundary Aquifers and responds to the pressing need of increasing the knowledge on their physical and socioeconomics characteristics. It is an integral component of the UNESCO’s International Shared Aquifer Resource Management (ISARM) Initiative and the Transboundary Waters Assessment Programme (TWAP).
The GGRETA Project will conduct in-depth assessments of three selected case studies:
1. The Esquipulas-Ocotepeque-Citalá (Trifinio) Aquifer (El Salvador, Guatemala, Honduras)
2. The Stampriet-Kalahari/Karoo Aquifer (Namibia, Botswana, South Africa)
3. The Pretashkent Aquifer (Kazakhstan, Uzbekistan)
The GGRETA Project adopts a 2-step approach to multi-country resource management by:
• Building recognition of the shared nature of the resource, and mutual trust through joint fact finding and science based diagnostics (Component 1); and
• Reaching consensus on transboundary governance mechanisms through consultative process (Component 2).
The expected project outcomes include a thorough assessment of the transboundary aquifers, a common information management system and monitoring program and the establishment of transboundary cooperation mechanisms.
The duration of the project (Component 1) is 2013-2015.
