Why are sandstorms becoming more common in the Middle East?

From Saudi Arabia to Iraq and Kuwait to Iran, sandstorms have been blanketing the Middle East, causing delays to flights, school closures and thousands being admitted to hospital with breathing difficulties.

The severe weather caused by the strong winds, known as Shamal winds in the Gulf, has led many governments to take proactive measures. These follow warnings from experts that climate change could worsen and lead to more severe weather events in the coming years.

In the UAE, a countrywide weather alert was issued on Wednesday with forecasts of sandstorms and dusty, windy weather. The warning came a day after a dust storm blanketed Abu Dhabi, reducing visibility to only a few hundred metres across the city and causing a major drop in air quality, according to the Air Quality Index.

In Saudi Arabia, about 1,285 people were admitted to hospitals in Riyadh in one day suffering from respiratory problems as a result of the sandstorm.

Iraq experienced the brunt of the storms this week when its eighth dust storm since mid-April descended on Monday. At least 4,000 people were treated at hospitals for breathing problems and the storm has led to the closure of airports, schools and public offices across the country.

Why do Gulf Arabs call dust storms ‘Shamal winds’?

People in the Gulf are accustomed to frequent sand and dust storms and have attached the Arabic word “Shamal”, which means northern, to the phenomenon owing to the direction of the winds.

Are increasing temperatures causing sandstorms?

While the exact causes of sand and dust storms are not yet fully known by scientists, many experts point to a correlation with deforestation and desertification to explain why more of these storms have become more frequent in recent years.

Banafsheh Keynoush, a non-resident scholar with the Middle East Institute’s Iran Programme, said sand and dust storms often originated in countries with limited vegetation, where there were fewer barriers to strong winds.

Is water mismanagement in Iran and Iraq to blame?

Experts in the region who have followed the sand and dust storms over the years have said mismanagement of water resources in countries such as Iran and Iraq, where rivers have dried up, has caused an increase in the frequency of such storms hitting the region.

Enric Terradellas, a meteorologist with the World Meteorology Organisation’s sand and dust storm prediction centre, told the BBC that the increased frequency of sand storms was directly related to a decrease in the flow of rivers in Iraq and Iran owing to the construction of dams.

What are the effects of dust storms and are there benefits?

While dust storms have affected health and economies in the region, some experts also say the sand and dust storms carry nutrients from the Sahara.

“Dust contains nutrients and these small particles have a very positive impact for microscopic plant-like organisms called phytoplankton that live in the ocean.”

What are governments doing to change it?

Saudi Arabia’s Crown Prince Mohammed bin Salman has said $13 billion is lost each year across the region due to dust storms.

To counter that, he announced the Green Saudi Initiative and Green Middle East Initiative last March to reduce carbon emissions by 60 per cent in the region and plant 50 billion trees in the world’s biggest afforestation project.

In the UAE, there has been investment in new technology to help the country to better equip itself for potential dust storms after Masdar Institute of Science and Technology announced the launch of its real-time dust storm forecasting system in 2016.
