The City of Cape Town is leading the way in preserving its rivers with a unique approach to water monitoring. Scientists use the South African Scoring System version 5 (SASS5) to identify macroinvertebrates in rivers, providing crucial data to gauge the health and water quality of these essential water bodies. This approach, coupled with the city’s cuttingedge technology and a deep understanding of local ecology, serves as an inspiring example for cities grappling with their own ecological challenges. The dedicated scientists at Cape Town’s laboratories and rivers are a testament to the importance of human skill and knowledge in preserving our natural environment.
