Population and areal statistics for 199 Transboundary Aquifers

At present 366 Transboundary Aquifers (TBAs) and 226 Transboundary Groundwater Bodies - as defined in the European Union Water Framework Directive - have been delineated (IGRAC and UNESCO-IHP, 2015). Progress in research and efforts towards joint management of Transboundary aquifers are steadily increasing, although there are still few TBAs which have been studied in detail or which are covered by some form of international agreement.
