Media Release: Garden Route Mountains Key to SA’s Water Future

During a recent workshop hosted by the World Wildlife Fund (WWF), South Africa has once again highlighted the importance of the Outeniqua and Tsitsikamma Mountains as critical water-producing landscapes for the Southern Cape.
These mountain catchments form part of South Africa’s Strategic Water Source Areas (SWAs) often called the country’s “natural water factories”. Although these areas cover less than 10% of the country’s land surface, they generate around half of the water that ends up in rivers and dams.
“For farmers, the message is clear: without healthy mountain catchments, there is no long-term water security,” says Cobus Meiring of the Garden Route Environmental Forum (GREF).
According to GREF, almost every catchment in the Garden Route is negatively impacted by invasive alien plants. These invasives reduce streamflow, damage soil health and weaken the ability of rivers to recover after drought.
The situation is made more challenging because of geography. Most coastal catchments in the Garden Route are short and flow quickly from the mountains to the Indian Ocean. This means there are very few opportunities to build large dams, making the protection of natural catchments even more important for agriculture.
South Africa is already a water-scarce country, and climate change is expected to bring hotter and drier conditions to many farming regions. However, the country still has a major advantage: a well-defined network of SWSAs that, if protected, can secure water supply for the future.
Over decades, South African engineers built world-class dams and inter-basin transfer schemes. But infrastructure alone cannot solve the problem. Without healthy mountain ecosystems, the system simply cannot function optimally.
The focus now is on cooperation between farmers, municipalities, conservation organisations and landowners to protect these vital catchments before further damage is done.
For the Garden Route and the wider agricultural sector, the message from the workshop was simple: protecting water source areas is not only an environmental priority – it is an economic one.
