Water Wheel Nov/Dec 2025: Estuaries

Abstract

ESTUARIES From macro to micro: Tools for monitoring estuarine health and recovery Feature South Africa’s estuaries are in crisis. A massive chemical spill near the uMhlanga Estuary on the KwaZulu-Natal coast a few years ago exposed their fragility, but also revealed powerful tools scientists are using to track damage, recovery, and the fight against pollution. Article by the Institute of Natural Resources and partners. South African rivers and estuaries are under serious threat. As national water demand soars and water quality plummets in many parts of the country, the challenge of monitoring and protecting aquatic ecosystems becomes increasingly urgent. The manner in which the impacts of acute and chronic pollution on aquatic systems are managed and mitigated is critically important in maintaining and restoring impacted aquatic ecosystems.
