Integrated Water Resources Management (IWRM) is increasingly part of Resilience Food Security Activity (RFSA) programming. Yet the meaning of IWRM is not always clear, nor is where to go for more information or what activities should be done to implement IWRM. IWRM and water resources management (WRM) are also different things, but the difference between them is not always clear. This learning note, written by PRO-WASH, an initiative funded by the United States Agency for International Development (USAID)’s Bureau for Humanitarian Assistance (BHA) and led by Save the Children, aims to fill these gaps.
