Zürcher Nachrichten - Iraqis cover soil with clay to curb sandstorms

Iraq has long suffered from sand and dust storms, but in recent years they have become more frequent and intense as the country falls prey to the effects of climate change.

Sand and dust storms -- driven by severe drought, rising temperatures and deforestation -- have cloaked cities and villages in an endless ochre haze, grounded flights and filled hospitals with patients suffering from breathing difficulties.

Iraqi authorities have warned that these suffocating storms will intensify further, adding urgency to address the root of the problem.

In a relatively small area between the cities of Nasiriyah and Samawah, not far from ancient Sumerian ruins, labourers are working hard to stabilise the soil by applying a layer of moist clay 20–25 centimetres thick.

The project also includes planting heat-tolerant seedlings like Prosopis and Conocarpus to further stabilise the soil.

"The main goal is to reduce the impact of transboundary dust storms, which may reach Kuwait, Saudi Arabia and Qatar," said Udai Taha Lafta from UN-Habitat, which is leading the project to combat sandstorms with Iraqi expertise.

"It is a vital area despite its small size, and will hopefully help reduce dust storms next summer," Lafta said.

A short-term objective is to shield a southern highway where many traffic accidents have occurred due to poor visibility during dust storms.

- 'Slow but steady' -

The Ministry of Environment estimates that Iraq now faces about 243 storms per year, and the frequency is expected to increase to 300 "dust days" by 2050 unless drastic mitigation measures are adopted.

In 2023, Iraqi authorities teamed up with the UN-Habitat and the Kuwait Fund for Arab Economic Development in areas that have been identified as major sources of sandstorms.

The project has been implementing several methods in three southern areas, including digging water canals and supplying electricity to pump water from the Euphrates river, preparing barren lands for vegetation.

One of the project's ultimate goals is to increase green spaces and for farmers to eventually sustain the lands after droughts and chronic water shortages have drastically reduced agricultural areas.

Qahtan al-Mhana, from the agriculture ministry, said that stabilising the soil gives agricultural efforts in sandy areas a chance to endure.

He added that Iraq has extensive "successful" experience in combating desertification and dust storms by stabilising sand dunes.

Since the 1970s, the country has implemented such projects, but after decades of turmoil, environmental challenges have largely fallen by the wayside.

With the severe recent impact of climate change, "work has resumed," said Najm Abed Taresh from Dhi Qar University.

"We are making slow but steady progress," Taresh said.
