A generation ago, the vanishing of the Aral Sea became global shorthand for environmental desolation. Today the region has become a test bed for a resilient future.

It was the first human-made ecological disaster of the modern era.
In 1960, the Aral Sea was the world’s fourth largest lake, a rich and productive ecosystem teeming with carp, bream, and other species—by one estimate, it provided a sixth of all fish consumed in the Soviet Union. Hundreds of feet deep and hundreds of miles across, the sea was a world unto itself for the people who lived and fished on its shores and for the sailors who crossed it.
But change was coming. In 1968, Pravda, the official state newspaper of the Soviet Union, carried a story with an astonishing prophecy. This world would soon vanish, it said. Already the water level had started to fall, and it would fall further, its edges creeping away from the fishing towns on its shores, the lake bed changing to desert. By the turn of the century, “essentially, the Aral Sea will no longer exist.”
There was no magic behind the prophecy—just math. In the preceding years, Soviet officials had built large-scale irrigation projects that diverted the Amu Darya and Syr Darya, the rivers that fed the Aral Sea, into cotton production. Without their inflow, there was nothing to replace the water lost naturally through evaporation. For a brief time, the region enjoyed the best of both worlds: the lake, with its productive fisheries and mild climate, and the cotton industry, with the hard cash it earned. But as the rivers turned away, the lake shrank and shrank to less than 10 percent of its mid-century footprint, leaving behind a salt-encrusted desert.
The prophecy had been duly engineered: The Aral Sea as such no longer existed. “From an environmental perspective, it was a huge mistake,” says Bulat Yessekin, an environmental policy expert who spent decades working on Central Asian water access issues with international nonprofit groups.
Today the Aral Sea stands not only as a worldwide symbol of catastrophe but also as the first domino to fall in a freshwater crisis. Iran’s Lake Urmia has also shrunk over the past half century by 90 percent, as has Lake Chad in Central Africa. In the United States, the Great Salt Lake in Utah has become so salty because of water loss that its brine shrimp are at risk of dying out. All these crises are tied together with the pressures of human population growth and climate change.
But some conservationists are now looking to the fate of the Aral Sea and asking another question: If humanity can create ecological disaster, can we also undo it?
