GGRETA: Governance in Transboundary Aquifers

The Groundwater Resources Governance in Transboundary Aquifers (GGRETA) 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 transboundary groundwater governance.
