Transboundary groundwater governance in the Guarani Aquifer System: reflections from a survey of global and regional experts

The document presents survey results from global and regional experts on the governance of the Guarani Aquifer System. Experts identified gaps in regulation and data, noted that contamination and overdrafting are currently localized, and viewed groundwater as a state-administered public resource. While a formal transboundary agreement is progressing, the findings emphasize the necessity of governance at local and national scales.

• Experts believe that groundwater withdrawal and quality are not sufficiently regulated, and that there is a lack of adequate data and information.
• Contamination and the over-extraction of groundwater are currently viewed as being primarily localized and in early stages along international borders.
• Groundwater is perceived as a shared resource managed by the state for public use rather than as private property.
• Despite progress toward a formal transboundary aquifer agreement, governance at the local and national levels remains critical.
