Groundwater Governance: The Challenges of Administrative Practice
13:00-14:30 Buenos Aires / 18:00-19:30 CEST | Tuesday 22 September 2026 | Webinar no. 87
Background
Effective groundwater management depends on having the right systems in place to turn knowledge into action. Across Latin America, administrative and economic realities can shape what is possible in practice, from how groundwater policies are implemented to how resources are allocated and competing needs are addressed.
Against this backdrop, IWRA’s Latin America and Caribbean (LAC) Geographic Chapter launched Transboundary Aquifer Systems in Latin America, a five-part webinar series running from August to October 2026 examining the various challenges and opportunities relating to groundwater management across the region.
The third second session is taking place Tuesday 22 September at 13:00 ART/ 18:00 CEST and, like all the sessions in the series, it will be held in Spanish, with simultaneous English translation via subtitles.
Part 3: Groundwater Governance: The Challenges of Administrative Practice
Groundwater management is shaped by more than science and technical knowledge. Across Latin America, decisions about groundwater are also influenced by how institutions work, how responsibilities are shared, who has access to water, how it is financed, and the different interests involved.
This session brings together experts from across the region to discuss the practical realities of managing groundwater. It will explore the challenges faced by governments, institutions and water users, as well as the different needs and interests that can shape decisions. The discussion will also look at ways to overcome these challenges and support more sustainable and effective groundwater management.

About the webinar series: Transboundary Aquifer Systems in Latin America
Drawing on more than two decades of experience with the Guaraní Aquifer and other transboundary systems in the region, leading experts shared their findings and discussed with the audience practical approaches to foster knowledge exchange and strengthen groundwater governance in Latin America and beyond.
Overall, the series aimed to examine the various scientific, climatic, governance, and policy dimensions of transboundary systems in the region, through a combination of expert presentations, panel dialogues, and audience participation.
The webinar series was designed to follow a logical progression, with each session exploring a different aspect of transboundary aquifer systems while contributing to a broader understanding of their governance and management in Latin America.
All sessions started with presentations, followed by a structured panel discussion, a roundtable Q&A, and conclusions provided by the moderator.
The five sessions were held in Spanish, with simultaneous English interpretation available in subtitles.
