RIYADH: Saudi Arabia possesses some of the healthiest coral reefs in the Red Sea, and is committed to preserving and restoring them, the Kingdom’s Deputy Minister of Environment, Water and Agriculture, Dr. Osama Faqeeha, said.
His remarks came during the inaugural meeting of the governance committee of the Global Coral Reef Research and Development Accelerator Platform, which has been announced following a meeting of the initiative’s founding committee, which comprised 16 member states of the G20 in addition to the EU countries.
During the meeting, Faqeeha was elected inaugural chairman of the platform’s governance committee, while Jennifer Koss, director of the Coral Reef Conservation Program of the US National Oceanic and Atmospheric Administration, was elected vice president.
Faqeeha said: “We welcome the Global Coral Reef Research and Development Accelerator Platform, which was announced by G20 leaders with the aim of improving coral conservation operations around the world and restoring them with a set of superior scientific and technical methodologies, and as a much-needed international collaborative effort to secure the future of coral life.”
He said that “the emergence of vaccines to protect against COVID-19 in record time is a testament to the effectiveness of concerted international scientific efforts to confront global challenges. This is what we hope to achieve in this platform, to confront the deterioration of coral reefs and the possibility of their permanent extinction from the world’s seas and oceans.”
Koss, said: “The US was pleased when the Kingdom drew our attention, during its recent presidency of the G20, to the urgent need to allocate greater resources and employ more innovative technologies in order to conserve global coral.”
She added: “This platform provides a unique opportunity to bring together the world’s scientific and coral management experts to complement current coral research and continue efforts to protect them, at a time when we are defining the future of our coral reefs, which are the basis for countless services that we cannot afford to lose in our ecosystem.”
The platform will accelerate research and development of coral reefs, and promote the next generation of science and technology needed to secure a future for reefs in combatting climate change and other pressures.
The research program will engage a global multidisciplinary community of scientists, coastal managers, technologists and innovators, guided by a strategic plan and objectives proposed by the platform’s scientific and advisory committee.
The platform will also connect existing national, regional and international research and development programs, engage the private sector in supporting these efforts, provide advanced research training to scientists from all countries and will facilitate access to scientific information and research and testing facilities around the world.
It will then provide the resulting new technologies and sciences, and allow them to support efforts on the ground to conserve and restore coral reefs.
The platform has designated King Abdullah University of Science and Technology (KAUST) to serve as a central meeting point for the platform and program management, in recognition of its proven track record in coral reef research, its proven capacity for global research collaboration, its management of proposals from scientific institutions around the world, and its state-of-the-art laboratories for coral reef research and world-class facilities to host international conferences and meetings. The university will support the center’s operations at no cost to the G20, as an extension of its strong commitment to saving the world’s coral reef ecosystems.
KAUST President Tony Chan said: “Since its establishment, coral reef research in the Red Sea has been one of the university’s focus and strengths, so this global effort motivates and inspires us, as we offered to be a central meeting point for the platform to direct the necessary resources, talents and efficient ideas to achieve the platform’s goals and protect disturbed coral ecosystems around the world.”
Carlos Duarte, professor of marine science at KAUST and acting executive director of the platform, called for the need “to act as custodians of our planet — for the health of our oceans, and for future generations.”

How researchers in Saudi Arabia are turning desalination waste into valuable resources
- Industry experts are working on technology to recover minerals from the highly saline waste liquid produced from desalination.
- Brine, a byproduct from turning sea water into fresh water, can also be repurposed for energy production, KAUST professor says
RIYADH: Saudi Arabia has established itself as a global leader in the rapidly advancing water desalination market, doubling its production capacity, while developing new technology to repurpose the harmful byproduct of the process — brine.
While desalination is effective for achieving water sustainability, producing drinking water from sea water in arid regions, it leaves behind a highly concentrated saline fluid. If this brine is disposed of back into the sea without treatment, it poses a potential danger to marine ecosystems.
Simply put, brine is highly concentrated seawater that contains contaminants, including chemicals used during the desalination process.
“The chemicals should be all neutralized,” said Noreddine Ghaffour, a research professor at the Water Desalination and Reuse Center at King Abdullah University of Science and Technology (KAUST).
He told Arab News that “there is no reason to dump chemicals into the sea, because they are all negatively affecting marine life, including chlorine and antiscalants.”
Water desalination scientists in Saudi Arabia have developed technologies to neutralize chemicals in brine before discharge and to disperse salt over a radius of up to 2 km when reintroduced into the sea.
Ghaffour, who was granted Saudi citizenship for his work and expertise on desalination, said that researchers and industry experts believe the future of the process is in recovering minerals, while treating the brine and achieving zero liquid discharge.
While around 70 percent of Earth is covered in water, only 2.5 percent of it is fresh, of which 1 percent is easily accessible, according to the National Geographic website.
Water desalination separates salt ions from sea water to make it safe for consumption. Salinity levels vary by body of water; for example, the Red Sea has 40 grams of salt per liter, while the Arabian Gulf’s salinity is 45 grams per liter.

The three main water desalination technologies employed in Saudi Arabia are: multi-stage flash distillation, a thermal process using evaporation and condensation; multiple-effect distillation, which uses electrical energy to break down water ions; and reverse osmosis, which separates water molecules through a semipermeable membrane.
All three technologies produce brine, but reverse osmosis plants generate lower quantities compared with the other two methods.
Reverse osmosis, according to Ghaffour, uses a method called membrane separation, where osmotic pressure is overcome by a semipermeable membrane that filters out salt ions, allowing only water molecules to pass through.
Ghaffour explained that although the semipermeable membrane effectively filters out about 99 percent of salts, some still manage to pass through, producing brine.
Moreover, osmotic pressure — the force applied to a solution to prevent a solvent from passing through a semipermeable membrane — requires a lot of electrical energy.
“Electricity is one of the most expensive energy forms… the main problem with (reverse osmosis) is that we do this under pressure,” the KAUST professor said.
He added: “The more salt, the higher the osmotic pressure. In order to pass only water molecules through the membrane, we need to apply a pressure which is higher than the osmotic pressure.
“And the osmotic pressure in Red Sea water, for instance, is 30 bar… so we need a pressure higher than 30 bar, which is a very high pressure.”
He also explained that “recovery” refers to “how much water we recover from the sea,” adding that “if the recovery is 50 percent, this means that salt contents are doubled.”
Ghaffour said selecting the correct location for a desalination plant is highly important. Authorities must choose sites with a reliable water intake that will not disrupt marine ecosystems or impact densely populated areas.
According to the UN Environment Programme, unless waste water is properly treated and dispersed, it may form a dense plume of toxic brine, which can degrade coastal and marine ecosystems.
Increased salinity and temperature can reduce dissolved oxygen levels and contribute to the formation of “dead zones” — areas where few marine species can survive.
Ghaffour said that while brine is bad for the environment, it has not caused significant global environmental harm. Over the past 30 to 40 years, Saudi Arabia and the Gulf region have experienced few negative side-effects from the desalination process, he said.
Concern over waste water from desalination returning to the sea at a higher temperature is less of an issue with the reverse osmosis method, Ghaffour said. “We have the same temperature as sea water, maybe one degree more, which is affordable.”
Researchers are determined to achieve zero liquid discharge, which involves treating brine until only solids remain. However, this process also concentrates all the salts in the same place.
To remove salt ions from brine, a complex and costly process called mineral recovery is used.
The challenge in mineral recovery lies in the fact that high-value minerals, such as lithium, rubidium, and uranium, are present in brine at very low concentrations.
To make the process efficient and economically viable, further technological advancements are needed.
Currently, “there are no technologies to handle this huge volume,” Ghaffour said. “We are talking about huge volumes of water, like 1 million tons of water (recovered) every day, it’s higher than a river.”
Several technologies have been developed for mineral recovery on a smaller scale. One method involves chemical treatments that precipitate different salts in stages, starting with calcium carbonate and ending with lithium.
Another mineral recovery method involves the use of ion exchange membranes or absorbents designed to capture specific minerals, such as lithium.
One of the largest areas of current research is the magnesium hydroxide family, particularly for its applications in the cement and concrete industry.
Saudi Arabia is already using nanofiltration technology to produce magnesium from magnesium-rich waters, with the next step being the extraction of magnesium hydroxide for cement production.
Expensive and critical minerals like rubidium — which costs around $3,000 per kilo — as well as uranium and lithium, are of great interest, but are costly to extract due to their low concentrations, requiring significantly more energy in the process.
From a commercial perspective, businesses prefer to purchase lithium from produced water — a byproduct of oil and gas production — rather than from brine.
Brine can also be repurposed to enhance the efficiency of the desalination process. Due to its high osmotic potential, brine can be used for energy production.
Ghaffour said that several companies are utilizing reverse electrodialysis to generate energy, which is then used to power the reverse osmosis process.

In addition, to achieve a circular carbon economy, reverse electrodialysis can be combined with brine dilution for mineral recovery, allowing part of the brine to be reused in an efficient closed-loop system.
“This is what I call a seawater factory,” Ghaffour said. “We take seawater and we produce everything from seawater without polluting back.
“Many experts are saying that in the future, desalinated water, which is what we need most, will itself be a byproduct, because we will have so many more valuable products from the sea. Then this desalinated water will be just one of the byproducts.”
However, he believes that turning this vision into reality will take time.
“We have to distinguish between two things. One is science and the second one is technology scale-up.”
In September 2024, Lihytech, a KAUST startup, announced a partnership with Aramco to strategically collaborate on recovering lithium from oilfield brines using direct lithium extraction technology and a membrane developed at KAUST.
Ghaffour is also collaborating with a Singaporean company, MediSun Energy, to integrate desalination with energy and mineral production, aiming to optimize these processes as a whole. A pilot facility has already been installed in China, with plans for another installation in Saudi Arabia.
“The whole world is working on this (mineral recovery and optimizing desalination). We will see a lot of developments in this, in my opinion,” he said.

France on the back foot in Africa after Chadian snub
- Chad abruptly ended its defense cooperation pact with France
- Experts say that without Chad, French army will struggle to run other Africa operations
NAIROBI/GENEVA: A French plan to significantly reduce its military presence in West and central Africa risks backfiring and further diminishing the former colonial power’s influence in the region at a time when Russia is gaining ground.
A French envoy to President Emmanuel Macron this week handed in a report with proposals on how France could reduce its military presence in Chad, Gabon and Ivory Coast, where it has deployed troops for decades.
Details of the report have not been made public but two sources said the plan is to cut the number of troops to 600 from around 2,200 now. The sources said Chad would keep the largest contingent with 300 French troops, down from 1,000. However, in a surprise move that caught French officials on the hop, the government of Chad — a key Western ally in the fight against Islamist militants in the region — on Thursday abruptly ended its defense cooperation pact with France. That could lead to French troops leaving the central African country altogether.
“For France it is the start of the end of their security engagement in central and Western Africa,” said Ulf Laessing, director of the Sahel Programme at the Konrad Adenauer Foundation in Mali.
“Chad was the aircraft carrier of the French army, its logistical headquarters. If Chad doesn’t exist, the French army will have a huge problem to keep running its other operations.”
In a further blow to France, Senegalese President Bassirou Diomaye Faye told French state TV on Thursday it was inappropriate for French troops to maintain a presence in his country, where 350 French soldiers are currently based. France has already pulled its soldiers out from Mali, Burkina Faso and Niger, following military coups in those West African countries and spreading anti-French sentiment. Paris is also shifting more attention to Europe with the war in Ukraine and increasing budgetary constraints, diplomats said.
The review envisions the remaining French soldiers in the region focusing on training, intelligence exchange and responding to requests from countries for help, depending on their needs, the sources said. Chad’s move to end the cooperation deal had not been discussed with Paris and shocked the French, according to the two sources and other officials. France, which wants to keep a presence in Chad in part because of its work to help ease one of the world’s worst humanitarian crises unfolding now in neighboring Sudan, responded only 24 hours after Chad made its announcement.
“France takes note and intends to continue the dialogue to implement these orientations,” the foreign ministry said in a statement.
One of the two sources, a French official with knowledge of Chadian affairs, said Chad’s government appeared to have seen the French decision to more than halve its military presence there as a snub. Chad also felt the French would no longer be in a position to guarantee the security of the military regime led by President Mahamat Idriss Deby, this source said.
Macron had backed Deby despite criticism since Deby seized power following the death of his father, who ruled Chad for 30 years until he was killed in 2021 during an incursion by rebels. Deby won an election held this year.
In its statement on Thursday evening, released hours after the French foreign minister had visited the Sudanese border in eastern Chad with his counterpart, Chad’s foreign ministry said N’djamena wanted to fully assert its sovereignty after more than six decades of independence from France. It said the decision should in no way undermine the friendly relations between the two countries. Earlier this year, a small contingent of US special forces left Chad amid a review of US cooperation with the country.
The French drawdown, coupled with a US pullback from Africa, contrasts with the increasing influence of Russia and other countries, including Turkiye and the United Arab Emirates, on the continent. Russian mercenaries are helping prop up the military governments of Niger, Mali and Burkina Faso, and are also fighting alongside them against Islamist militants. However, French officials and other sources played down Russia’s ability to take advantage of the French setback in Chad, at least in the short term. The French source familiar with Chadian affairs noted that Russia and Chad back rival factions in Sudan’s war. Russia also has major military commitments in Syria and the war in Ukraine.
2 migrants dead, one missing off Tunisia: reports
- Tunisia and neighboring Libya have become key departure points for migrants
- Each year, tens of thousands of people attempt to make the crossing
TUNIS: Two unidentified bodies were recovered off Tunisia’s eastern coast after a migrant boat capsized, local media reported on Friday, with one person still missing and 28 rescued.
Most of the passengers were Tunisian, according to the reports, which said that the boat had set sail from Teboulba, a coastal town some 180 kilometers south of the capital Tunis.
Tunisia and neighboring Libya have become key departure points for migrants, often from other African countries, who risk perilous Mediterranean Sea journeys in the hopes of reaching better lives in Europe.
Each year, tens of thousands of people attempt to make the crossing. Italy, whose Lampedusa Island is only 150 kilometers (90 miles) from Tunisia, is often their first port of call.
In late October, the bodies of 15 people believed to be migrants were recovered by authorities in Monastir, eastern Tunisia.
And in late September, 36 would-be migrants — mainly Tunisians — were rescued off Bizerte in northern Tunisia.
Since January 1, at least 103 makeshift boats have capsized and 341 bodies have been recovered off Tunisia’s coast, according to the interior ministry.
More than 1,300 people died or disappeared last year in shipwrecks off the North African country, according to the Tunisian FTDES rights group.
The International Organization for Migration has said that more than 30,309 migrants have died in the Mediterranean in the past decade, including more than 3,000 last year.
Iraq tries to stem influx of illegal foreign workers
- The Labor Ministry says the influx is mainly from Syria, Pakistan, and Bangladesh, also citing 40,000 registered immigrant workers
KARBALA: Rami, a Syrian worker in Iraq, spends his 16-hour shifts at a restaurant fearing arrest as authorities crack down on undocumented migrants in the country better known for its own exodus.
He is one of hundreds of thousands of foreigners working without permits in Iraq, which, after emerging from decades of conflict, has become an unexpected destination for many seeking opportunities.
“I’ve been able to avoid the security forces and checkpoints,” said the 27-year-old, who has lived in Iraq for seven years and asked that AFP use a pseudonym to protect his identity.
Between 10 in the morning and 2 a.m. the next day, he toils at a shawarma shop in the holy city of Karbala, where millions of pilgrims congregate every year.
“My greatest fear is to be expelled back to Syria, where I’d have to do military service,” he said.
BACKGROUND
Authorities are trying to regulate the number of foreign workers as the country seeks to diversify from the dominant hydrocarbons sector.
The Labor Ministry says the influx is mainly from Syria, Pakistan, and Bangladesh, also citing 40,000 registered immigrant workers.
Now, the authorities are trying to regulate the number of foreign workers as the country seeks to diversify from the currently dominant hydrocarbons sector.
Many, like Rami, work in the service industry in Iraq.
One Baghdad restaurant owner admitted that he has to play cat and mouse with the authorities during inspections, asking some employees to make themselves scarce.
He said that not all those who work for him are registered because of the costly fees involved.
Some of the undocumented workers in Iraq first came as pilgrims. In July, Labour Minister Ahmed Assadi said his services investigated information that “50,000 Pakistani visitors” stayed on “to work illegally.”
Despite threats of expulsion because of the scale of the issue, the authorities, at the end of November, launched a scheme for “Syrian, Bangladeshi, and Pakistani workers” to regularize their employment by applying online before Dec. 25.
The ministry says it will take legal action against anyone who brings in or employs undocumented foreign workers.
Rami has decided to play safe, even though “I want” to acquire legal employment status.
“But I’m afraid,” he said. “I’m waiting to see what my friends do, and then I’ll do the same.”
Current Iraqi law caps the number of foreign workers a company can employ at 50 percent, but the authorities now want to lower this to 30 percent.
“Today we only allow qualified workers for jobs requiring skills” that are not currently available, Labor Ministry spokesman Nijm Al-Aqabi said.
It’s a sensitive issue — for the past two decades, even a foreign workforce has dominated the robust oil sector. But now the authorities are seeking to favor Iraqis.
“There are large companies contracted to the government” which have been asked to limit “foreign worker numbers to 30 percent,” said Aqabi.
“This is in the interests of the domestic labor market,” he said, as 1.6 million Iraqis are unemployed.
He recognized that each household has the right to employ a foreign domestic worker, claiming this was work Iraqis did not want to do.
One agency launched in 2021 that brings in domestic workers from Niger, Ghana, and Ethiopia confirms the high demand.
“Before, we used to bring in 40 women, but now it’s around 100” a year, said an employee at the agency.
The employee said it was a trend picked up from rich countries in the Gulf.
“The situation in Iraq is getting better, and with higher salaries, Iraqi homeowners are looking for comfort.”
A domestic worker earns about $230 a month, but the authorities have quintupled the registration fee, with a work permit now costing more than $800.
In the summer, Human Rights Watch denounced what it called a campaign of arbitrary arrests and expulsions targeting Syrians, even those with the necessary paperwork.
HRW said that raids targeted both homes and workplaces.
Ahmed — another pseudonym — is a 31-year-old Syrian who has been undocumented in Iraq for the past year and a half.
He began as a cook in Baghdad and later moved to Karbala.
“Life is hard here — we don’t have any rights,” he said
“We come in illegally, and the security forces are after us.”
His wife did not accompany him. She stayed in Syria.
“I’d go back if I could,” said Ahmed. “But life there is very difficult. There’s no work.”
