Rhine's Toxic Past: Lessons for India's Rivers

Forty years ago, on November 1, 1986, a fire at a Sandoz agrochemical warehouse near Basel, Switzerland, led to a major environmental disaster. Water used to combat the blaze washed tons of toxic chemicals into the Rhine River, resulting in widespread fish deaths and alarming visuals across Europe. This incident occurred shortly after other significant environmental catastrophes, intensifying public concern.

In response, Rhine riparian countries met and tasked the International Commission for the Protection of the Rhine (ICPR) with developing a plan. The Rhine Action Programme (RAP), approved in October 1987, aimed to restore the river by 2000, facilitating the return of species like salmon and ensuring future drinking water supplies. Significant improvements in wastewater treatment and accident prevention were implemented.

Today, the Rhine has seen substantial water quality improvement, supporting over 70 fish species, with some extinct species reintroduced. The writer observed this rejuvenation firsthand in 2015, noting the clean river traffic and public engagement, such as at Cologne's Hohenzollern Bridge.

Contrastingly, India's rivers, like the Yamuna, face severe pollution, with Delhi's stretch being particularly dire. Despite numerous environmental acts and action plans launched since the 1970s, including the Ganga and Yamuna Action Plans and Namami Gange, desired outcomes have not been achieved.

Since 1986, India has spent over Rs 24,298.32 crore on the Ganga and Yamuna alone, yet polluted river stretches have increased dramatically, affecting 271 rivers by 2025. The Rhine's recovery serves as a stark lesson for India's ongoing river cleaning challenges.
