Why do we need to care about transboundary aquifers and how do we solve their issues?

Building 20 years TBA experience through a three-pillar framework (assessment, cooperation-collaboration, shared management), key elements addressing are described, including multidisciplinary approach, identification hotspot zones, local vs border-wide approaches, appropriate funding models, an increased recognition role value each TBA.
