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

Abstract

As the reliance on transboundary groundwater is increasing globally, it is important to understand and address the specific 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, identification of hotspot zones, local vs border-wide approaches, appropriate funding models, and an increased recognition of the role and value of each TBA.

Topical Collection: International Year of Groundwater—managing future societal and environmental challenges

“…A socio-hydrogeology approach (Re 2021) is based on local community involvement, with a direct increase of awareness of water issues by the citizens, and with mutual learning through transdisciplinarity. At a wider scale, transboundary aquifers pose a management challenge that requires international cooperation to be effectively implemented (Rivera et al 2022; this issue).…”

Water Balance Calculation for a Transboundary Aquifer System between Estonia and Latvia

“…Unlike surface water, groundwater is not easily observable, and consequently, the awareness of groundwater protection remains low with aquifer mismanagement examples worldwide [5][6][7][8][9][10]. Unsustainable management practices in one country can adversely impact the groundwater conditions in neighboring countries, leading to conflicts and emphasizing the need for timely and joint action on transboundary aquifer management strategies [11]. Therefore, the hydrological systems functioning and vulnerability to pollution and depletion are essential for sustainable water management, particularly in transboundary contexts [12].…”
