Chantal Nativel: Fighting River Pollution and Restoring Johannesburg’s Rivers

Chantal Nativel is an environmental activist taking on river pollution in Johannesburg, where neglected waterways have become dumping grounds for waste, sewage and plastic. Rather than waiting for somebody else to solve the problem, Chantal decided to start with the river running through her own community and see what one determined person could do.

What began with picking rubbish out of the water grew into a much larger campaign to restore and protect Johannesburg's rivers. Chantal's work demonstrates how environmental activism can begin at an intensely local level, with one person noticing a problem, refusing to accept it and persuading others to become part of the solution.

In our conversation, Chantal talks about the reality of river pollution and what she has learned from spending years working directly in and around polluted waterways. We discuss the sources of the waste entering Johannesburg's rivers, the effect on communities and wildlife, and the enormous challenge of keeping waterways clean when new pollution continually flows downstream.

But cleaning a river is only part of the answer. Chantal explains why lasting change also depends on understanding where pollution comes from, working with communities and encouraging people to see rivers not as convenient places to dump waste but as living ecosystems worth protecting.

Her story is also about persistence. Environmental problems can feel overwhelming, particularly when they involve failing infrastructure, water pollution and behaviour that no individual can change alone. Chantal's response has been to concentrate on what can be done: organise clean-ups, build community involvement, raise awareness and keep drawing attention to what is happening in the water.

We talk about environmental activism in South Africa, community action and the relationship between healthy rivers and healthy neighbourhoods. Chantal also reflects on the people she has met through her work and the way practical action can change how communities think about the natural spaces around them.

River pollution is not simply an environmental problem. Polluted waterways affect people, wildlife and the wider ecosystems on which communities depend. Chantal's work shows why conservation and social change often have to happen together, particularly in an urban environment such as Johannesburg.

This is a conversation about river pollution, environmental responsibility and the power of grassroots action. Chantal's experience is a reminder that restoring a river can begin with something very small: one person deciding that walking past the problem is no longer enough.
