Why do we need to care about transboundary aquifers and how do we solve their issues?. Hydrogeology Journal, 1-4.https://doi.org/10.1007/s10040-022-02552-yhttp://hdl.handle.net/10566/8774As the reliance on transboundary groundwater is increasing globally, it is important to understand and address the specifc issues raised by the assessment and management of transboundary aquifers (TBAs). Building on 20 years of TBA experience and through a three-pillar framework (assessment, cooperation-collaboration, shared management), the key elements to addressing TBA issues are described, including a multidisciplinary approach, identifcation of hotspot zones, local vs border-wide approaches, appropriate funding models, and an increased recognition of the role and value of each TBA.Transboundary aquifersGroundwater and societyWater-resources managementSocio-economic aspectsArticle
