Poor Soil Management Fuels Sand And Dust Storms Across The Middle East
The Middle East is no stranger to sand and dust storms.
Iran, Iraq, Kuwait, the United Arab Emirates, and Saudi Arabia are among the countries hit hardest by this transboundary problem, which costs billions of dollars each year in damages to infrastructure and health systems.
In May, Iran's local media reported severe sand and dust storms in the southeast near the border with Afghanistan, which swept through the area, sent hundreds to the hospital with respiratory illnesses, and disrupted local livelihoods.
'Dust storms happen when strong winds lift loose, dry, and fine soil particles from barren or degraded land surfaces into the atmosphere,' says Nima Shokri, professor of geo-hydroinformatics at the Hamburg University of Technology in Germany.
'Unlike people, dust particles don't require visas to cross international borders- they can travel effortlessly thousands of kilometers from one country to another,' adds Shokri.
The Middle East is naturally prone to strong winds, extreme heat, and arid landscapes—factors that create an ideal environment for sand and dust storms when coupled with climate change.
But decades of poor water management, which have dried up lakes, rivers, and wetlands that once helped contain these storms, have turned sand and dust storms into a pressing challenge for the region, with many consequences.
Food and water insecurity, air pollution, conflict, and forced migration are just a few examples.
Meanwhile, as governments across the Middle East struggle to combat the growing problem of SDS, experts highlight soil degradation as a significant contributing element that demands urgent global attention.

According to the UN's Food and Agriculture Organization, healthy soil is defined as having the ability to perform functions such as retaining water or sustaining plant and animal life. Soil then becomes degraded when it loses vegetation and organic matter, like manure, and is exposed to long periods of drought.
Research indicates that in the Middle East, soil in many parts of the region has been harmed because of the excessive extraction of groundwater for irrigation and farming, as well as climate change.
This mix of problems has caused a big issue for many countries called soil salinization, where water dries up and leaves salt behind, preventing crops from growing.
Scientists say Iran, Saudi Arabia, and Afghanistan are among the nations in the region experiencing the highest salt increases in their soil.
In a part of the world with no shortage of environmental problems, soil degradation poses an added threat to food, water, and the resilience to cope with disasters such as floods and wildfires.
But that's not all that it does.
Pete Smith, a professor of plant and soil science at the University of Aberdeen in Scotland, told me in an interview that poor soil management can also increase the severity of sand and dust storms.
'Failing to retain plant cover on the soil and practices like overgrazing lead to the destabilization of soil, making it easier for particles to be picked up and carried by the wind,' adds Smith.
On the other hand, scientists have discovered that wet and heavy soil is less likely to release dust into the air quickly or in large quantities. This means the drier the land, the worse the dust storms, experts say.
'Dust emissions greatly depend on soil moisture,' says Paolo D'Odorico, a professor of environmental science at the University of California, Berkeley.
Particularly in the Middle East, 'there are a few basins of internal drainage that are drying out and exposing the sediment to the action of wind and consequent dust storms,' D'Odorico adds.

The United Nations Sustainable Development Goals (SDGs) plan to help nations achieve peace and prosperity by 2030. They include objectives like fighting climate change and making sure everyone has access to clean and safe water.
However, the list does not include the need for well-functioning soil, an essential component of the SDGs that experts say the international community is overlooking.
'It would be naive to think we can achieve any of these goals without giving soil the proper attention it deserves,' says Shokri.
'In the absence of that, the whole foundation of sustainable development will begin to crumble,' he adds.
The World Bank reckons that over 40% of the land in the Middle East has already lost its productivity. As droughts become increasingly severe and temperatures rise, scientists believe that healthier soil can be a key solution for mitigating these problems.
When it comes to sand and dust storms, 'it can certainly reduce the impact and severity for communities," says Smith.
Decision makers 'should definitely discuss it as a tool for tackling climate change, food security, and combating land degradation and desertification,' he adds.
'This is truly the definition of a transboundary issue in need of serious global cooperation,' Shokri adds.

Wisconsin piling up costs from more floods, report finds. And that was before this deluge.
As southeastern Wisconsin reckons with the growing toll of extreme weather events − such as last weekend's 1,000-year flood − the region faces mounting costs to infrastructure, possible displacement, the loss of personal belongings and irreplaceable memories, as well a serious impacts to mental and physical health. A new report by the Wisconsin Policy Forum outlines how Wisconsin has seen an increase in damage caused by flooding, in turn leading to dramatic spikes in flood insurance claims and payouts. In something of an astonishing fluke of timing, the report was in the works long before this month's flood. That made the conclusions all the more relevant. Climate change − which is caused by human use of fossil fuels − is warming the planet, allowing it to hold onto more water and leading to supercharged rain events. The devastating impact of these storms will continue to grow with inaction as climate change is warming the planet at a pace faster than ever before. Floods are Wisconsin's second-most frequent disaster declaration, resulting in $123.7 million in damages since 1999, the report says. People need to be ready, whether that means buying flood insurance as individuals or broadly making sure local and state leaders have plans in place to help communities respond and recover more quickly, said Tyler Byrnes, senior research associate at the Wisconsin Policy Forum and author on the report. Here are four takeaways from the new report. A dramatic increase in flood damage There has been a massive jump in Wisconsin flood damage in the last three decades, according to the new report. There has also been a series of massive flood events — in 1997, 1998, 2008, 2010 and 2018 — leading to spikes in claims that totaled nearly $114 million in damages. The largest was after a 2008 record rain event when 12 inches of rain fell over the course of two days in southern Wisconsin, which led to $49.0 million in damages claimed. The most recent in 2018 led to $24 million in damages, most within Dane and Sauk counties. And although this month's flood wasn't part of the report, based on the data, Byrnes estimates that the Aug. 9 and 10 flood event will likely be one of the highest set of claims Wisconsin has ever seen. Current projections show that over the next 20 years, most of the state will have a higher likelihood of heavy rains and, presumably floods, increasing the chance for spikes in property damage. More: Landmark study finds Great Lakes have entered a new era with climate change, extreme events Milwaukee leads the state in flood insurance claims Flood insurance claims are largely concentrated in southern Wisconsin due to topography, development and the fact that more people live in the southern part of the state with higher property values, Byrnes said. In southwestern Wisconsin, communities are situated in steep landscapes and within valleys, and clustered near rivers. Southeastern Wisconsin receives the most amount of rain and is more developed, leading to more runoff that can damage building and infrastructure. From 1978 to 2023, Milwaukee has had the most flood damage impact compared to other cities in the state at about $25 million, followed by Fort Atkinson at nearly $11 million and Fond Du Lac at about $9 million, the report said. More: Extreme heat. Warmer water. More ticks. Fewer fish. Climate change report brings grim news. Wisconsin flood insurance premiums just above national average Flood insurance policies are managed by FEMA and private companies with premiums subsidized by the federal government. Policy holders pay different premium amounts depending on flood risk and property value. As of 2023, the median flood insurance policy for a single-family home in Wisconsin cost $804 each year, just above the national average of $786, according to the report. Local, state leaders need to prepare The report acknowledged Milwaukee's strides in implementing green infrastructure and investing in improved stormwater infrastructure. Those tools will be key to warding off flood damages for communities throughout Wisconsin, Byrnes noted. He also said local governments need to be tougher on limiting the impacts of development and should require measures to prevent water runoff. This kind of preparation will also come with tradeoffs, Byrnes said. Limiting impacts of development can increase costs, which is a sensitive issue when housing costs already are skyrocketing in some areas. It can also stop places from being developed entirely — which is a problem when there is a need for more housing stock. But there has to be a balance, Byrnes said, making sure there is enough affordable housing while also protecting people from catastrophic flood events.

After historic flood and devastating losses, Milwaukee begins a new path forward
Block after block across metropolitan Milwaukee, piles of soaked carpets, waterlogged appliances and furniture stained beyond recognition now slump in front yards and along sidewalks. These are spaces where summer should be lived, not filled with debris. The streets tell the story of families turned inside out by a 1,000-year flood, as cherished keepsakes, family photos, childhood drawings — in some cases, all the reminders of lives lived, now washed away. And in town centers, beloved restaurants, local shops, small businesses, cornerstones of the community where we gather and make memories are grappling with how to move forward. There's little doubt that climate change is here — whether it's wildfire smoke lingering in our air, warmer winters and disappearing ice on our Great Lakes or relentless summer heat waves. But those events seem to pass and life resumes. Not this time. This will take much longer. "It was a devasting event that just unfortunately caused a lot of heartache for people throughout the region," said Kevin Shafer, executive director of the Milwaukee Metropolitan Sewerage District. For years, scientists have warned about what can happen when climate change supercharges extreme weather events. This is exactly what they meant. As the planet warms, air can hold onto much more water, so when the weather conditions line up, like they did on Aug. 9 and 10, and into Aug. 11, storms can release more rain. A warmer climate also creates weather systems that move slower. More water from a storm that sticks around longer creates prolonged, heavy rainfall and flooding. The result is that it's become harder to use historical data because climate change is altering things so drastically; the past is no longer a good predictor of the future. Regardless, scientists say that climate change is increasing the likelihood that these intense deluges will happen within any given year. We were paying a price even before this month. A new report by the Wisconsin Policy Forum outlined how Wisconsin has seen an increase in damage caused by flooding, in turn leading to dramatic spikes in flood insurance claims and payouts. There are also serious impacts to mental and physical health. Floods are Wisconsin's second-most frequent disaster declaration, the same report said, resulting in $123.7 million in damages since 1999. And that dollar figure was compiled before this summer. So far, Milwaukee County has a preliminary estimate that damages to roads, park systems, bridges and waterways from this month's event is roughly $23 million. That number is expected to grow. The story is told in personal losses Of course, all those numbers have people behind them. There is Kevin Knitter, who told the Journal Sentinel that he and his wife Katie did not purchase flood insurance when they bought their Wauwatosa home because it was not in the floodplain. The Knitters evacuated as water filled their basement and rose into the first floor. They ended up in a rescue boat with their daughter, two dogs and a goldfish. And they learned the floodplain maps had changed in 2024, and their home was now inside the boundaries. And there is Eric Wagner, founder and CEO of the Lowlands Group, which owns Café Hollander, who got his first call about the Wauwatosa location at 6:30 a.m., on Aug. 10. Water had started coming into the basement kitchen, and eventually rose to four feet. 'When there's pressure from the river, the water starts getting into the drywall. There was equipment floating everywhere and the electrical got all burned out,' Wagner told the Journal Sentinel. He's now looking at a six-week reconstruction and costs approaching $1 million. At Paul Davis Restoration, roughly three calls per minute — yes, minute — have been coming in from customers needing help with flood damaged property. 'This is pretty unprecedented,' said Ariel Flary, business development manager. 'Every call that comes in, we call back and touch base and see if they still need service.' Flary said crews from Appleton and Waukegan, Illinois, have traveled, and occasionally stayed in hotels, to try to keep up with the calls for service. 'Some people have lost entire homes and then have been told they're not covered (by insurance),' Flary said, adding the company is also cautious about working its employees too much, and checks to make sure they get breaks and stay hydrated. More: River revival: Milwaukee's long-neglected Kinnickinnic River is on the verge of a revival Rain totals surpassed 10 inches in parts of Milwaukee County Since 1950, Wisconsin has become on average 17% wetter — or roughly 5 inches more precipitation, according to the latest Wisconsin Initiative on Climate Change Impacts report. The southern two-thirds of Wisconsin has experienced the biggest increase in rainfall. The Aug. 9 to 10 storm ranks second for a two-day rain event since the National Weather Service began recording that data in 1871. Calling it a 1,000-year flood event can be somewhat confusing because the label is based on probability, not time. It doesn't mean that it happens once every 1,000 years. Instead, it's a flood that has a 1-in-1,000 chance of occurring in any given year. According to rainfall totals from the sewerage district, the highest total rainfall amount in the city of Milwaukee — and county, too — during this storm was recorded at 8135 W. Florist Ave., which had nearly 15 inches from Aug. 9 to 11. River Hills had the highest total amount of rain out of Milwaukee County suburbs at nearly 11.5 inches. Within the overall storm, the most intense period was specifically during a 12-hour stretch from 7 p.m., Aug. 9, to 7 a.m., Aug. 10, according to Andy Boxell, meteorologist at the National Weather Service. In Waukesha County, a reporting station just south of Menomonee Falls registered 12.05 inches in that time frame. Pewaukee recorded 12.61 inches; Waukesha received 9.75 inches. In Washington County, Germantown logged 10.58 inches during that span. 211 damage reports continue to rise As people with flood damage continue to assess their situation, and some realize they can't go it alone, the number of calls to 211 keeps growing. The confidential helpline helps with a wide range of needs, like housing, food, transportation, and healthcare. It's the best connection to resources at this point, Milwaukee Health Commissioner Michael Totoraitis said. More than 11,500 requests for flood-related services have come in to 211 from across Milwaukee County and the surrounding Waukesha, Ozaukee and Washington counties as of the afternoon of Aug. 14. Of that number, roughly 85% of the requests for service came from Milwaukee alone. The helpline saw a spike in calls on Tuesday and Wednesday, with over 3,100 reports each day. Preliminary 211 data showed the highest number of requests came out of Milwaukee County's northwest side, along with West Milwaukee, in particular from ZIP codes 53218, 53209, and 53216. Reports from 211 calls also included basement water depths, utility disruptions and structural damage. The 53218 ZIP code, which includes the north side's Silver Spring and Hampton Heights neighborhoods, stood out with 1,851 damage reports, the highest among all the ZIP codes listed. It also had the highest number of utility disruptions, with 1,448 reports, and 850 structural damage reports. It's average water depth report was 26 inches. The basement water reports across Milwaukee County averaged 19.2 inches. The deepest average basement water was reported in 53219, just west of Jackson Park on the city's south side, at 35 inches. More than 12,000 calls reported utility disruptions and almost 7,000 reported of structural damage. The data is self-reported, according Vickie Boneck, the spokesperson for IMPACT 211, the designated provider of 211 services in southeastern Wisconsin. The numbers continue to change as 211 continues to receive calls and messages. For example, Boneck noted that as water is receding in basements, the reports, too, show a decrease in the average inches reported. Of the data collected, 2-1-1 reported more roughly 5,000 referrals for storm-related needs, including connecting those who reached out to the county's office of emergency services, post disaster cleanup tools and supplies, disaster food stamps and food pantries. Milwaukee officials have repeatedly urged residents to report damage to 211. The reports help bolster the push for federal assistance to address widespread damage from the flooding. The reports also serve as another source of data the city is using to identify the hardest-hit areas. For example, the Milwaukee Health Department is using the data to determine where to send cleaning kits. He encouraged residents to submit damage reports either by calling or submitting a report online when call times are longer. And, he said, residents should urge others to report their damages as well. "That 211 data is really guiding what the city can do," Totoraitis said. "And then as we get – fingers crossed – that money unlocked from the feds, that we can then use that information to prioritize helping someone get a new water heater or whatever that support looks like." He also urged residents to use their insurance, take photos of damage and write down a timeline to help the claims process move forward. The 211 data provides one view into the extent of the damage. Other data collected by the city is also helping guide its response. That includes information from the Department of Public Works, which is marking areas that need bulky waste pickup. The Milwaukee Department of Neighborhood Services is also inspecting homes in the city and neighboring suburbs to assess the extent of the damage. As if the afternoon of Aug. 14, there had been 2,916 homes inspected. Of those, 5% were destroyed, 55% had major damage, 17% had minor damage and 12% were listed as "affected," the lowest level of concern, according to the department. In 11% of the homes, inspectors were unable to gain entry to the premises. Despite damage, Milwaukee on its way to climate resiliency While many parks and green spaces across the region were overwhelmed during the storm, they ultimately did what they were designed to do − absorb and hold water, minimizing damage to nearby homes and businesses. Shafer pointed to Wauwatosa's Hart Park, which was inundated but helped prevent even worse flooding downstream. 'This storm reinforced that the work we've done so far is worthwhile,' Shafer said. 'Without these investments, the damage would have been significantly worse.' Still, he emphasized that more must be done. "This was a wakeup call for us," Shafer said. "And I think it's going to lead us to much better discussions about the future." While the devastation is undeniable, Shafer said the region's much more prepared than it was 30 years ago. He called for a continued focus on green infrastructure and a watershed-wide approach – strategies that include removing impervious surfaces and improving park spaces to handle stormwater more effectively. These efforts not only protect people's homes and businesses but also build long-term resilience against increasingly intense storms. "We've taken huge steps over the last 25 years," Shafer said. "And we need to continue that for the next 25." Ricardo Torres, Bridget Fogarty, Cathy Kozlowicz, Rachel Bernhard and Sophia Tiedge contributed to reporting on this story.

Climate change is making things even worse for the poorly housed
Climate change is making Hong Kong's summers hotter. Yet tens of thousands of residents remain sardined into homes smaller than a parking space, where staying cool is a luxury few can afford as the climate warms. In small, enclosed spaces with little ventilation or cooling, indoor temperatures can soar past 100°F (37.7°C), posing serious health risks for the city's most vulnerable.
