Welcome to the information management system of the Groundwater Resources Governance in Transboundary Aquifers (GGRETA) project. The GGRETA project responds to the pressing need of increasing the knowledge on the physical and socioeconomic characteristics of transboundary aquifers. The project conducts in depth assessment of transboundary aquifers in three case study locations: Southern Africa, Central Asia, and Central America. This portal is developed to collect, store, visualise and share structured information, in order to support groundwater governance in these aquifers.

|El Salvador, Guatemala, Honduras||GGRETA results indicate that the original “Trifinio Aquifer” actually consists of two individual aquifers: the ‘Esquipulas’ in Guatemala and the ‘Ocotepeque-Citalá’ shared by Honduras and El Salvador. The aquifers are connected by the River Lempa, which contributes to the discharge and recharge of the aquifers.|
|Botswana, Namibia, South Africa||The Stampriet Transboundary Aquifer System is a large aquifer system situated in the southern part of the Kalahari and it is shared between Botswana, Namibia and South Africa. The aquifer system is well representative of groundwater resources in hot semi-arid regions of Africa, where groundwater is the primary source of water.|
|Kazakhstan, Uzbekistan||The Pretashkent Aquifer is an artesian transboundary aquifer system shared by Kazakhstan and Uzbekistan. A constant lowering of groundwater heads has been observed which is caused by overexploitation. Since groundwater in the Pretashkent Aquifer is practically non-renewable this situation calls for renewal of transboundary cooperation about sustainable use of the aquifer.|
