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

A research paper based on a survey of global and regional experts regarding the governance of the Guarani Aquifer System in South America, focusing on regulation, resource ownership, and the state of groundwater quality and quantity.

• Experts surveyed believe that groundwater withdrawal and quality are under-regulated and that the available data and information are insufficient.
• Contamination and overdrafting of the aquifer are currently viewed as being primarily localized and incipient along international borders.
• The prevailing view among respondents is that groundwater is a shared resource managed by the state for public use, as opposed to being private property.
• While a formal transboundary aquifer agreement is being progressed, experts emphasize the importance of governance at local and national scales.
