The document proposes establishing a Water Resource Management Network (WRMN) to address South Africa's water challenges through multidisciplinary collaboration. It outlines the current water challenges around scarcity, quality, financing, and resource management. The WRMN would utilize a Water Need Clusters Approach with different institutes collaborating within clusters focused on specific water problems. This approach allows multidisciplinary interaction and participation from any interested competent groups or institutes. The network would be managed through a structure of network chairs, cluster leaders, and task groups to identify needs and work towards solutions across different domains related to water resource management.
