WWF South Africa's 2016 report 'Water: Facts and Futures' details the critical state of the country's water security. It highlights that while only 8% of land generates 50% of river flow, these Water Source Areas are under-protected. The report identifies severe threats from invasive alien plants, failing engineered infrastructure (with 37% urban water loss), and widespread pollution from sewage and mining. It calls for a 'Water and Sanitation Revolution' focusing on nature-based solutions, groundwater management, and decentralized service delivery to ensure equitable access to safe water.
