The diversion of the Amu Darya and Syr Darya rivers for large-scale irrigation projects caused the Aral Sea to shrink drastically, resulting in a severe ecological disaster.12

The environmental and health consequences include:

  • Water Quality and Biodiversity: The lake’s salinity rose significantly, rendering the water undrinkable and destroying the local fishing industry by killing off native fish populations.13
  • Toxic Dust Storms: As the seabed was exposed, winds carried toxic dust—contaminated with salt, pesticides, and fertilizers—across the region, poisoning local drinking water and food supplies.13
  • Public Health Crisis: Residents, particularly the Karakalpaks, have suffered from high rates of illnesses, including throat cancers, anemia, and kidney diseases, alongside high infant mortality rates.12
  • Climatic Changes: The loss of such a large body of water led to a harsher local climate, characterized by more extreme winter and summer temperatures.12
  • Biological Hazards: The receding waters turned the former island of Vozrozhdenya into a peninsula, increasing accessibility to a site previously used for Cold War-era biological weapons testing, including buried anthrax spores.1
