Latest / The Story of Uzbekistan: Silk Road Kingdoms and Soviet Legacy — Fexingo History / The Aral Sea Disaster: Uzbekistan's Vanished Inland Ocean
Transcript
- Lucas: So we've talked a lot about Uzbekistan's rivers — the Amu Darya, the Syr Darya — and how they were diverted for cotton. But I think we need to talk about what happened downstream, where those rivers used to end. Luna: The Aral Sea. Lucas: Exactly. And I don't think most people realise just how big it was. In the 1960s, it was the fourth-largest inland lake in the world — bigger than any of the Great Lakes except Superior. And now? It's almost gone. Luna: I've seen the photos — ships in the desert. It's surreal. Lucas: That's Moynaq, a former fishing port in Karakalpakstan. When I first read about it, the numbers are staggering. Between 1960 and 2020, the Aral Sea lost about 90% of its volume. The surface area shrank from 68,000 square kilometres to less than 8,000. By 2007, it had split into three separate lakes. Luna: Why the 1960s? What shifted? Lucas: That's when the Soviet irrigation projects really kicked into high gear. They had this plan — part of Khrushchev's Virgin Lands campaign and the earlier GOELRO electrification plan — to turn Central Asia into a cotton powerhouse. The Amu Darya and Syr Darya, which fed the Aral Sea, were diverted into canals like the Karakum Canal, the longest in the world. By the 1980s, something like 90% of the water that should have flowed into the sea was being used for irrigation. Lucas: And it wasn't just any irrigation — it was incredibly inefficient. The canals were mostly unlined, so water just seeped into the desert. And the crops, mostly cotton, are incredibly thirsty. The Soviets were treating the sea as a disposable resource. Luna: Was anyone sounding the alarm at the time? Lucas: A few scientists, but they were silenced. In the USSR, environmental data was often classified. It wasn't until the late 1980s, under Gorbachev's glasnost, that the full scale of the disaster became public. By then, the fishing industry had already collapsed. The town of Moynaq, which used to process 20,000 tons of fish a year, was suddenly 150 kilometres from the coast. Luna: And the health impact — I've read about the dust. Lucas: The dried seabed, now called the Aralkum desert, is full of salt, pesticides, and fertiliser residue from decades of runoff. Windstorms pick up this toxic dust and blow it across the region. Rates of cancer, respiratory disease, and birth defects in Karakalpakstan are among the highest in the world. It's a public health crisis that doesn't get nearly enough attention. Lucas: But there is a small success story. On the Kazakh side, they built the Kokaral Dam in 2005, which separates the North Aral Sea from the South. Water levels there have risen, fish are returning, and the climate has even started to improve locally. Luna: But the Uzbek side — the South Aral — is still drying up, right? Lucas: Unfortunately, yes. The South Aral is mostly gone, and Uzbekistan has not invested in similar restoration. The focus remains on cotton production, despite the ecological cost. It's a classic tragedy of the commons, playing out over decades. Lucas: And you know, thinking about this — about how a single policy decision, repeated over years, can reshape a landscape forever — it makes you appreciate the value of understanding history. Which is partly why we do this show. Luna: Yeah. And if someone listening today found this worth their time, they can support us at buy me a coffee dot com slash fexingo. Lucas: Exactly. That link — buy me a coffee dot com slash fexingo — it's the simplest way to keep these conversations going, ad-free. No pressure, but it helps. Luna: And we really mean that. Just knowing people are listening is great, but if you can toss in a coffee's worth, it makes a difference. Lucas: Alright, back to the sea. So after the split, the Eastern basin of the South Aral completely dried up by 2014. The Western basin is still there, but it's hyper-saline — almost nothing can live in it. There's a proposal to build a dam across the Ustyurt Plateau to save part of it, but it's a massive engineering challenge. Luna: And the climate effects — I've heard it's changed the weather in Central Asia. Lucas: Absolutely. The Aral Sea used to moderate the local climate. Without it, summers are hotter, winters are colder, and the growing season has shortened. Some studies suggest it's even affected precipitation patterns as far away as India. It's a planetary-scale example of how interconnected our systems are. Luna: What lessons do you think we should take from this? Lucas: First, that large-scale environmental engineering can have unintended consequences that dwarf the intended benefits. Second, that economic priorities need to be balanced with ecological sustainability. And third, that it's never too late to try — the North Aral shows that partial restoration is possible, even after decades of damage. Lucas: There's also a human lesson. The people of Karakalpakstan have lived through this collapse with relatively little voice in the decisions that caused it. Their story is a reminder that environmental justice is inseparable from political representation. Luna: And the Aral Sea's not just a Central Asian story — it's a global one. Lucas: Right. Other lakes around the world are shrinking — the Salton Sea in California, Lake Urmia in Iran. The Aral is a warning. And maybe, if we listen to it, we can avoid repeating the same mistakes elsewhere.
