This document is designed to collate information around Integrated Water Resources Management (IWRM) good practices and Sudanese case studies. It will form a baseline that can be used to inform project design and advocate for the up-scaling of IWRM implementation in humanitarian and development programme delivery in Sudan. Although IWRM has been used globally for several years and is accepted as a good practice, its implementation could be further improved, especially in developing countries like Sudan. Six case studies have been selected and documented as good practices in IWRM to create a baseline that can be used to advocate the up-scaling of IWRM implementation and provide lessons for others to map out their own IWRM strategy. The case studies are based on: environmental, economic and social sustainability; gender sensitivity; technical feasibility; participation; scaling up; vertical and horizontal coordination; integration; replicability and adaptability; and reduction of disaster/crisis risks.
