This document introduces integrated water resources management (IWRM). It discusses the global water crisis, including that over 2 billion people suffer water shortages and 1.1 billion lack access to safe drinking water. IWRM is presented as a framework that takes a holistic, cross-sectoral approach to managing water resources at the river basin level through participatory decision-making. The key elements of IWRM include considering the interdependency between different water uses, treating water as both an economic and social good, and establishing decentralized management structures that rely on economic instruments and stakeholder participation. Adopting a water management framework based on IWRM principles can help analyze policies, guide water allocation decisions, and facilitate consideration of relationships
