Q: Why did the Aral Sea dry up?

The cotton catastrophe: Aral Sea and forced labour

Soviet planners diverted the Amu Darya and Syr Darya to irrigate millions of hectares of cotton, collapsing the Aral Sea from the 4th-largest lake in the world to a toxic remnant within 40 years.

Updated

Uzbekistan produced ~6 million tonnes of raw cotton annually at Soviet peak (1980s), making it the world's 5th-largest cotton producer. This came at catastrophic environmental cost.

Timeline: - 1960: Aral Sea covers 68,000 km², supports a 60,000-tonne fishing industry. - 1960s–1980s: expansion of the Karakum Canal and dozens of irrigation networks diverts most of the Amu Darya water before it reaches the sea. - 1987: the Aral splits into a Northern (Small) and Southern (Large) Aral. - 2000s: the Southern Aral splits further. Total lake area drops below 10,000 km². - 2020: approximately 10% of 1960 volume remains.

Human consequences: - Muynak — once a fishing port, now 150 km from any water. Ship Cemetery a tourist attraction. - Health crisis: windblown salt and pesticides from exposed seabed cause respiratory disease, cancers, and birth defects across Karakalpakstan. - Climate change: regional temperatures became more extreme as the moderating lake influence vanished. - Forced labour: until 2022, the Uzbek government mobilised millions of citizens — including children and civil servants — for annual cotton harvests. International pressure and ILO monitoring ended the practice.

Recovery efforts: - The Kok-Aral Dam (2005, funded by World Bank) successfully stabilised the Northern (Kazakh) Aral, which has partially recovered. - The Southern (Uzbek) Aral is considered functionally dead — no viable recovery plan exists. - Uzbekistan is diversifying away from cotton toward fruit, vegetables, and textiles.

The Aral disaster is a UNESCO-documented case study in ecological collapse from agricultural overreach.
