Citizen participation in water governance can improve the relevance, implementation, and effectiveness of public policies. However, participation can be expressed in a great diversity of forms, on a gradient ranging from mere public consultation to shared governance of natural resources. Positive outcomes ultimately depend on the conditions under which participation takes place, with key factors such as leadership, the degree of trust among stakeholders, and the interaction of public authorities with citizens. Social network analysis has been used to operationalize participatory processes, contributing to the identification of leaders, intersectoral integration, strategic planning, and conflict resolution. In this commentary, we analyze the potential and limitations of participation in water governance and illustrate it with the case of the Campina de Faro aquifer in southern Portugal. We propose that stakeholder network analysis is particularly useful for promoting decentralized decision-making and consensual water resources management. The delegation of power to different interest groups is a key process in the effectiveness of governance, which can be operationalized with network analysis techniques.
