Going with the Flow: How Local Water User Associations Have Shaped Water Resource Management in Chile

Effective and sustainable water resource management requires flexibility and adaptation to local contexts. Our study analyzes the emergence and evolution of local water self-governing associations, reviewing how their struggles and conflicts, both with the public sector and among locals themselves, have been pivotal to achieving agreements and actions towards sustainable water management. Using an adapted version of the Combined Institutional Analysis and Development (IAD) and social–ecological system (SES) framework, also known as CIS, we conducted a comparative analysis of two distinct Chilean cases. This research highlights the critical role of historical factors alongside institutional support, political landscapes, and financial realities in shaping current water management practices. The findings suggest that when the actors are aligned and actions are taken to support local water user management, more efficient, sustainable, and less conflict-ridden water resource management occurs. Furthermore, this study reveals how the experiences, struggles, and successes of these local user associations have shaped national policies, particularly regarding the development of monitoring mechanisms and the promotion of public–private cooperation in water governance. These efforts have not only fostered more resilient water management systems but have also demonstrated the power of grassroots organizations in shaping broader sustainable policies.
