The aim of this article is to conduct an evidence-based analysis of stakeholder engagement in decision-making processes affecting multifunctional irrigation systems. The selection of case studies has allowed us to examine different tools that promote stakeholder engagement and good governance. The case studies show how stakeholder engagement in irrigation systems shapes hydrosocial territories: (1) by reducing tension between stakeholders, (2) by redirecting regional planning and strategy, (3) by highlighting water crises, (4) by decentralizing water responsibilities, and (5) by integrating values and beliefs from different stakeholders.
