KwaZulu-Natal is one of South Africa’s most water-rich provinces, with sparkling wetlands, dams and rivers that are home to a vibrant array of wildlife, and a hub of water sports like the Midmar Mile and Dusi Canoe Marathon. The uMngeni River and its tributaries (like the Msunduzi River) are of particular importance, supplying water to more than two-fifths of the province. The river is also unfortunately one of the country’s dirtiest. But this is something that Liz Taylor and Enviro Champ Nompumelelo Bhengu of the Duzi-Umngeni Conservation Trust (DUCT) in Howick are working hard to change. Nompumelelo is a paid citizen scientist; the eyes, ears and voice of the river, championing its health to her community and local authorities. She, like many other DUCT Enviro Champs, has been trained to monitor and record the health of the river three times a day, while also keeping an eye on illegal dumping sites, leaking sewers and burst drinking water pipes. Together, Nompumelelo and Liz are seeing real change being enacted through their work.
