Episode 25 - The Aral Sea - World's Worst Water Disaster?

In this episode of H2O and Beyond, I’m joined by historian Dr. Sarah Cameron to unpack the story of the Aral Sea — one of the greatest environmental catastrophes of the 20th century.

How did a massive inland sea in Central Asia nearly disappear?

What role did Soviet cotton production play?

And what happens to communities when an entire ecosystem collapses?

We dive into the Cold War politics behind the diversion of the Amu Darya and Syr Darya rivers, the rise of cotton as a “strategic crop,” and how irrigation infrastructure slowly strangled the sea.

We also explore the human side of the crisis — from fishing communities forced to abandon their livelihoods to toxic dust storms that reshaped public health in the region.
