Coastal erosion impacts Western and Eastern Cape
Coastal erosion is severely impacting South Africa's Western and Eastern Cape coastlines, driven by rising sea levels and intense storm surges. Cobus Meiring from the Garden Route Marine and Coastal Committee highlights the visible and measurable damage, threatening thousands of properties along the 3,000 km coastline. The Garden Route District Municipality notes that 290 estuaries and 42 micro-estuaries, stretching from the Orange River to Kosi Bay, are affected. The Council for Scientific and Industrial Research attributes the erosion to waves, tides, and rising sea levels, with storms causing the most severe damage. Local authorities are prioritizing coastal degradation in their planning, focusing on relocating infrastructure.
