Instead of drilling wells or purifying seawater, it will wring moisture from the air to create bottled water at a plant 20 kilometres (12 miles) from Dubai

Zero Mass Water, will use renewable energy instead of the fossil fuels that power the many desalination facilities in Dubai and the rest of the United Arab Emirates

Zero Mass isn’t going to rival bulk water processors any time soon. It will initially only be able to produce up to 2.3 million litres annually - about the volume of a typical Olympic swimming pool. The technology is still much more expensive than desalination for the same output of water. So Zero Mass’s will be in the same bracket as imported, high-end brands such as Evian and Fiji

Vicious Saudi autocrat Mohamed bin Salman has a new vision for Neom, his plan for a massive, $500 billion, AI-powered, nominally legally independent city-state of the future on the border with Egypt and Jordan. When we last left the crown prince, he had reportedly commissioned 2,300-pages’ worth of proposals from Boston Consulting Group, McKinsey & Co. and Oliver Wyman boasting of possible amenities like holographic schoolteachers, cloud seeding to create rain, flying taxis, glow-in-the-dark beaches, a giant NASA-built artificial moon, and lots of robots: maids, cage fighters, and dinosaurs.

Now Salman has a bold new idea: One of the cities in Neom is a line. A line roughly 105-miles (170-kilometers) long and a five-minute walk wide, to be exact. No, really, it’s a line. The proposed city is a line that stretches across all of Saudi Arabia. That’s the plan.

“With zero cars, zero streets, and zero carbon emissions, you can fulfill all your daily requirements within a five minute walk,” the crown prince continued. “And you can travel from end to end within 20 minutes.”AdvertisementThe end-to-end in 20 minutes boast likely refers to some form of mass transit that doesn’t yet exist. That works out to a transit system running at about 317 mph (510 kph). That would be much faster than Japan’s famous Shinkansen train network, which is capped at 200 mph (321 kph). Some Japanese rail companies have tested maglev trains that have gone up to 373 mph (600 kph), though it’s nowhere near ready for primetime.

Alwash, 52, a citizen of Iraq and the United States, is a hydraulic engineer and the director of Nature Iraq, the country's first and only environmental organization. He founded the organization in 2004 together with his wife Suzanne, an American geologist, with financial support from the United States, Canada, Japan and Italy. His goal is to save a largely dried-up marsh in southern Iraq. In return for giving up his job in California, Alwash is now putting his safety and health at risk.

Only 20 years ago, an amazing aquatic world thrived in the area, which is in the middle of the desert. Larger than the Everglades, it extended across the southern end of Iraq, where the Tigris and Euphrates rivers divide into hundreds of channels before they come together again near Basra and flow into the Persian Gulf. For environmentalists, this marshland was a unique oasis of life, until the Iraqi dictator Saddam Hussein, a Sunni, had it drained in the early 1990s after a Shiite uprising.

Within a few years, the marshland had shrunk to less than 10 percent of its original size. In a place that was once teeming with wildlife - wild boar, hyenas, foxes, otters, water snakes and even lions - the former reed beds had been turned into barren salt flats, poisoned and full of land mines. In a 2001 report, the United Nations characterized the destruction of the marshes as one of the world's greatest environmental disasters.

A black sealant sprayed on parking lots, driveways and playgrounds turns out to be the largest contributor to the rise of a toxic pollutant in urban lakes and reservoirs across America, according to a new U.S. Geological Survey study. Scientists saw concentrations of polycyclic aromatic hydrocarbons (PAHs) going up rapidly in the 1990s in areas of urban sprawl. PAHs have been known as a probable human carcinogen since the 19th century, when cancer struck chimney sweeps, said Peter Van Metre, a USGS scientist and a principal author of the report. PAHs also are toxic to fish and other aquatic plant and animal life.

An alternative sealant, an asphalt-emulsion-based one, has PAH levels about 1,000 times lower.Coal tar is a waste product of the coking of coal, a process used in making steel. Coal-tar-based sealant is more commonly used in the Midwest, South and East, and asphalt-based sealant is used more widely on the West Coast.

PAH levels in dust in apartments that had coal-tar sealant on the parking lot were 25 times higher than apartments that didn't have the sealant outside

An alarm blares occasional high-temperature alerts, but the buildings themselves are kept so frigid that aviators sometimes wear extra socks as mittens

Most of the civilian deaths acknowledged by the coalition emerge from this internal reporting process. Often, though, watchdogs or journalists bring allegations to the coalition, or officials learn about potential civilian deaths through social media. The coalition ultimately rejects a vast majority of such external reports. It will try to match the incident to a strike in its logs to determine whether it was indeed its aircraft that struck the location in question (the Iraqi Air Force also carries out strikes). If so, it then scours its drone footage, pilot videos, internal records and, when they believe it is warranted, social media and other open-source information for corroborating evidence. Each month, the coalition releases a report listing those allegations deemed credible, dismissing most of them on the grounds that coalition aircraft did not strike in the vicinity or that the reporter failed to provide sufficiently precise information about the time and place of the episode.

They speak of every one of the acknowledged deaths as tragic but utterly unavoidable. “We’re not happy with it, and we’re never going to be happy with it,” said Thomas, the Central Command spokesman. “But we’re pretty confident we do the best we can to try to limit these things.”

The problem with the headline about vegetarianism is that it suggests that the world is one unit, and that somehow resource constraints would affect the world in a more or less uniform way. Barring the emergence of some centralized global government, this won’t happen. Some people will always be able to afford meat and will consume it. In 50 years, some people will probably still eat as much as modern Americans. The question is how are we going to create a world that is food secure for billions. I’m very confident that we will go through multiple advances in crop science, etc. that will allow us to feasibly grow more than enough food for 9 billion people. Imagine 6-10 tonnes of harvest per hectare. I’m 100% a techno-optimist in that regard. I’m not, however, optimistic that we are guaranteed to sort out how to ensure that people are food secure, meaning that the food that is produced can reach people who have the purchasing power to acquire it. Ultimately, “food security of billions” will boil down to the ability of those billions to purchase  what they can’t grow themselves, and that is a complicated issue that was addressed by Malin Falkenmark in her talk(s), but by very few others

understanding how governments, private entities, etc. induce changes in human behavior. Governments tend to use the strong arm of the law, rather than creative incentives. Private companies on the other hand, have a very well-practiced and nuanced marketing sense, because they have to if they want consumers to purchase their products. Its surprising to me then that Nestle and PepsiCo the two mega-large corporate sponsors/ participants in this year’s World Water Week didn’t collaborate and host a special session on human behavior change, in a very applied practical sense

I’m excited by a “new” effort to develop an international standard method (ISO) for water footprinting assessments. I was at first fascinated by the idea of looking at “embedded water” in products, also known as the virtual water content of a product. A popular quote is 1000 litres of water to make 1 litre of milk, or 16000 litres of water for 1 kilogram of beef. National Geographic has created posters, and World Water Week’s corridors had large displays showing us how much water was required to make various food items and beverages. However, what does any of that mean? In what context was that beef grown? Are you assuming it was grain fed on a feedlot or grass fed in a country hillside? Are these beef cattle eating grain grown in tropical drylands (e.g. the Sahel in Africa), or temperate rainy areas (i.e. the Pacific Northwest of the USA)? Those details can make the difference between completely unsustainable and completely sustainable methods of food production. If the ISO standard can serve to improve the transparency and usefulness of the concept of water footprinting, then that would be an important achievement.

while supporting the development of its nuclear technology, America is insisting that Jordan purchase its reactor fuel on the nuclear market (it will “allow” Jordan to mine the uranium ore, but not convert it into fuel).  The Obama administration stresses that it will refuse to help Jordan if it makes use of its own uranium, and intends to model any deal with Jordan on the USA's recent nuclear agreement with the United Arab Emirates, who agreed to purchase their uranium on the international market, but reserve the right to renegotiate this deal if another country concludes an agreement on more favourable terms. Pursuing its right to enrich uranium without America's agreement would prove difficult for Jordan: the USA plays a powerful role in the Nuclear Supplier Group which monitors the sale of nuclear technology.  Moreover, many reactors from countries outside the USA contain American components which would require Jordan to gain America's approval to purchase.  But the USA's insistence that the country give up the right to use its own uranium seems to be a strategic miscalculation with the potential to alienate one of America and Israel's key Arab allies.  While the Jordanian government under reformist King Abdullah can certainly be criticised for its benign and even not-so-benign authoritarianism, it remains a positive presence in the Israel-Palestinian peace process (and the strongest ally of the USA in the Arab world). In fact, it was its willingness to 'help' in the war on terror that caused concern for human rights campaigners. Undermining the country's nuclear intentions when Jordan has done more than it is required to do in terms of tranparency and negotiation gives the impression that America will always treat Middle Eastern nuclear projects with suspicion, and that there's little incentive to cooperate.

To knowingly alienate Jordan by undermining the country's right to energy independence would be an act of masochism by Israel, particularly when the country's nuclear programme presents an opportunity to develop a model of transparency in nuclear energy development, and a chance to strengthen a more moderate presence in the region at a time when it is sorely needed.

“If they think they will build a nuclear reactor here, the Bani Hassan tribe will go nuclear,”

Irhamouna (or give us a break), a loose grouping of prominent Mafraq citizens, geologists, lawyers and youth activists who have mobilised against the planned nuclear reactor

With the presence of grey water produced by the nearby Khirbet Al Samra Wastewater Treatment Plant for reactor cooling, JAEC maintains that the Mafraq site became the only suitable alternative.

“Whoever cuts a branch from my forest, I will cut his head,” Sultan Mehmed II, who led the Ottomans into Istanbul, is said to have ordered in the 1400s. Today, thousands of trucks carrying soil and construction materials kick up dust along the roads north of Istanbul, depleting those forests that had been protected by sultans for five centuries.

Canal Istanbul (also called Istanbul Kanal), a massive shipping canal meant to route traffic from the Bosporus some 18 miles (30 kilometers) to the east. The homes alongside the new seaway will be replaced with upscale residential and commercial areas. With construction set to start there any day now, real estate speculators descend on the area, clamoring for locals to sell them their land

When completed, the canal will turn the densest part of the city, including its historic center, into an island. The area also straddles one of the world’s most active fault lines.

With every flood or bout of extreme heat or cold, the jihadists would reappear, often supplementing their sales pitches with gifts. When a particularly vicious drought struck in 2010, the fifth in seven years, they doled out food baskets. When fierce winds eviscerated hundreds of eggplant fields near Kirkuk in the spring of 2012, they distributed cash. As farming communities limped from one debilitating crisis to another, the recruiters—all members of what soon became the Islamic State—began to see a return on their investment.

By the time the Islamic State (also known as ISIS) seized this swath of Iraq—along with most of the country’s west and north—in a brutal summer-long blitzkrieg in 2014, few locals were surprised to see dozens of former fertilizer market regulars among its ranks.

Across rural Iraq and Syria, farmers, officials, and village elders tell similar stories of desperate farmhands swapping backhoes for assault rifles. Already battered by decades of shoddy environmental policies, which had hobbled agriculture and impoverished its dependents, these men were in no state to navigate the extra challenges of climate change. And so when ISIS came along, propelled in large part by sectarian grievances and religious fanaticism, many of the most environmentally damaged Sunni Arab villages quickly emerged as some of the deep-pocketed jihadists’ foremost recruiting grounds.

the Syria climate conflict narrative is deeply problematic.[2] Not only is the evidence behind this narrative weak. In addition, it masks what was really occurring in rural Syria (and in the country’s northeast region in particular) prior to 2011, which was the unfolding of a long-term economic, environmental and political crisis. And crucially, the narrative largely originated from Syrian regime interests in deflecting responsibility for a crisis of its own making. Syria is less an exemplar of what awaits us as the planet warms than of the complex and uncomfortable politics of blaming climate change.

much of Syria and the eastern Mediterranean region experienced an exceptionally severe drought in the years before the onset of Syria’s civil war: the single year 2007–2008 was northeastern Syria’s driest on record, as was the three-year period 2006–2009

Environmentally, the model relied above all on the super-exploitation of water resources, especially groundwater—a problem which by the early 2000s had become critical. And economically, Syrian agriculture had become highly input dependent, reliant on continuing fuel subsidies in particular.

One in every seven working Yemeni is employed in producing and distributing qat, making it the largest single source of rural income and the second largest source of employment in the country after the agriculture and herding sector, exceeding even the public sector, according to the World Bank. Many of Yemen's poorest families admit to spending over half their earnings on the leaf. "Qat is the biggest market in Yemen, bigger than oil, bigger than anything," said Abdulrahman Al-Iryani, Yemen's former water minister and founder of 'qat uprooting', a charity which supports farmers in replacing qat shrubs with coffee plants.

qat is entwined in all of Yemen's problems

the cultivation of qat - the least taxed, most subsidized and fastest-growing cash crop in Yemen - consumes 40 percent of irrigated farming land

For a foreign power to successfully occupy, control and integrate the Bedouins into the new state-system entailed the disruption all of the above; from the nomadic lifestyle and lack of social stratification, to ourfi laws, loyalty to the tribe, and the notion of collective identity

turning Egypt into a modern nation-state. To that end, he had to first re-organize Egyptian society, streamline the economy, train a bureaucracy to effectively run a centralized government, and build a modern military. “His first task was to secure a revenue stream for Egypt. To accomplish this, (he) ‘nationalized’ all the Egyptian soil, thereby officially owning all the production of the land.”13 As a result, all tribal or communal rights to landownership were not legally recognized. With the disenfranchisement of land came the disenfranchisement of image. In order to exert control over Sinai, the government restricted movement, imposed taxes and demanded payment for camping and grazing. It also started to co-opt certain individuals from various tribes, and favor some tribes over others, which in turn disrupted the Bedouin hierarchy based on sex, age and seniority.14

Sykes-Picot agreement in 1916. The agreement divided the Arab provinces of the Ottoman Empire outside the Arabian Peninsula into areas of British and French control or influence. As a roaming people whose livelihood depended on seasonal movement from one pasture to another, cementing the border left them with no choice but to become sedentary. This severance from “fundamental elements in their economic, commercial and social universe,”15 exposed the Bedouin to a whole new level of poverty

During the past few months, the people of Khuzestan had strongly objected to the implementation of the project known as Behesht Abad, which aims to transfer water from the Karun River to the central provinces of the country. The Behesht Abad project involves the transfer of more than 1 billion cubic meters [1.3 billion cubic yards] of water from the tributaries of the Karun River to the central provinces of Iran such as Yazd, Isfahan and Kerman. The project, which would stop the flow of Karun into the Persian Gulf, has been faced with strong opposition from the people and environmental activists of Khuzestan province.  

If we survey the local websites, we can clearly see that for the people of this region issues such as employment, environmental pollution and hydraulic basins are more important than political issues

this water is needed for preserving the water quality in the Shadegan Wetland, an international wetland and one of the largest wetland ecosystems of the world. The Karun River, in its course through Khuzestan, provides water for several large and small wetlands that are very important in maintaining the local ecosystem

The marsh is dotted with atmospherically controlled chambers that contain the same amount of CO2 that the planet may be exposed to by the year 2100 - roughly double what it is today. "They're like time capsules. We are simulating the future inside them," says Dr Megonigal. "We're trying to travel forward in time by subjecting these plants to the conditions the whole world will be subjected to a hundred years from now."

Coastal wetlands are the first defence against climate change and the 60-hectare (148-acre) salt marsh at the heart of the Smithsonian Environmental Research Center has been home to some of the most important ecological studies of the past 40 years.
