Sand and Dust Storms

sand and dust

Dust and sand storms (DSS) are atmospheric phenomena where strong winds lift dust and sand particles from the surface and transport them across long distances. These storms impact public health, agriculture, infrastructure, and ecosystems, and contribute to land degradation.

According to UNCCD, over 2,000 DSS events occur annually, with increasing frequency and intensity, especially in drylands.

Causes of DSS

  • Land degradation and vegetation loss

  • Drought and climate change

  • Exposure of dry lakebeds (e.g., Aral Sea)

  • Unsustainable grazing and land use

  • Construction and farming without protective measures

Regional Context: Central Asia and Russia

DSS are increasingly common in Central Asia and southern Russia. In Kazakhstan, Uzbekistan, and Turkmenistan, major sources include desertified zones and dust hotspots around the dried Aral Sea. In Russia, DSS are recorded annually in steppe regions such as Kalmykia and Astrakhan.

Uzbekistan’s Involvement

Uzbekistan is one of the most affected countries by DSS. The dried bed of the Aral Sea is a major dust source. Uzbekistan is responding through:

  • Large-scale afforestation (over 1.7 million hectares)

  • Participation in UNCCD DSS initiatives

  • Development of a national DSS strategy

  • Proposal to host a regional DSS monitoring center

Impacts

  • Air pollution and respiratory health risks

  • Soil fertility loss

  • Damage to infrastructure

  • Contamination of water bodies

  • Transboundary environmental threats

Response Measures

UNCCD and WMO are advancing a global DSS monitoring platform. Recommended actions include:

  • Vegetation restoration and windbreak planting

  • Mapping and monitoring of dust sources

  • Sustainable rangeland management

  • Early warning systems and regional cooperation
