The Arabian Gulf and the Red Sea are major sources of seafood and vital reservoirs of two of the most precious resources: water and oil.

The rich marine ecosystems within these bodies of water are characterized by a diverse array of unique and indigenous plants and animals that play crucial roles in maintaining ecological balance.

However, these sensitive habitats may experience significant physical and chemical stresses if the natural equilibrium is disturbed. 

Saudi Arabia is taking a leadership role on the global stage with its innovative and patented technologies developed by the Saudi Water Authority’s Water Technology Innovation and Research Development Institute.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

WTIIRA-SWA has created a groundbreaking dual brine concentration design that combines a nanofiltration system upstream of a reverse osmosis system and a membrane brine concentration system downstream.

This technology enables the extraction of two valuable brine streams: one that consists of concentrated and purified monovalent ions, which can be used to produce high-purity sodium chloride and bromine, and another that is rich in divalent ions usable for manufacturing various calcium and magnesium salts.

Such innovation not only contributes to the sustainability of desalination processes but also opens new avenues for economic viability, connecting the desalination industry to a range of applications in sectors such as chlor-alkali production, pharmaceuticals and cosmetics.

These initiatives are focused not only on efficient desalination, but also on the responsible management of brine as a resource rather than merely as a waste product.

Another noteworthy achievement in this field is the extraction of vaterite calcium carbonate, distinguished by its unique chemical properties, including high porosity, increased surface area, greater solubility and biodegradability.

These attributes make vaterite calcium carbonate especially suitable for controlled release in pharmaceutical formulations, serving as an effective carrier for drug delivery. By harnessing such advanced materials, WTIIRA-SWA underscores its commitment to innovation in resource recovery.

Moreover, WTIIRA-SWA has implemented several pioneering strategies to minimize the environmental impact of desalination brine and preserve the precious ecosystems surrounding the Kingdom.

Efficient technology implementation: Modern desalination plants in Saudi Arabia utilize advanced technologies that emphasize energy efficiency and environmental sustainability. 

Brine disposal management: In Saudi Arabia, the strategies for brine disposal are carefully considered. Detailed studies of dilution factors, dispersion patterns, and the assimilative capacity of the receiving marine environment are conducted to ensure that discharged brine is safely integrated without detrimental effects on marine life.

Monitoring and regulation: Rigorous environmental monitoring programs are established to assess the impact of desalination plant effluents on the marine ecosystem. 

Coastal ecosystem preservation: Strategic placement of desalination plants is intended to reduce impacts on sensitive coastal ecosystems. 

Research and development: Ongoing research and development initiatives aim to improve desalination technologies and processes further. 

Through these comprehensive approaches, WTIIRA-SWA is not only addressing the challenges of desalination but also setting a global standard for sustainability in the management of water resources.

Google Doodle commemorates 53rd UAE National Day

DUBAI: Google is commemorating the UAE’s 53rd National Day, also known as Eid Al-Etihad, with its latest Doodle marking the Emirate’s foundation day.

On this day in 1971, the leaders of Abu Dhabi, Ajman, Dubai, Fujairah, Sharjah and Umm Al-Quwain agreed to unite and established the UAE as an independent nation. The seventh emirate, Ras Al-Khaimah, joined the federation shortly after in 1972.

Abu Dhabi’s Sheikh Zayed bin Sultan Al-Nahyan became the first President of the UAE until he died in 2004.

The UAE Government has declared Dec. 2 and 3 as paid holidays for employees in both private and public sectors, with activities and celebrations lined up to celebration occasion.

Among the widely anticipated events include fireworks displays – particularly in Abu Dhabi and Dubai – as well as grand parades in each of the emirates.

The ongoing Sheikh Zayed Festival in Abu Dhabi’s Al-Wathba showcases three days of fireworks and drone shows, aside from a series of heritage show by the Eid Al-Etihad Caravan featuring camels adorned with the UAE flag and folk performances, highlighting the nation’s cultural pride.

This year’s grand ceremony will be held in Al Ain, and attended by the country’s rulers, it will be livestreamed on www.eidaletihad.ae on Dec. 2.

  • Tarique Rahman, others were found guilty in 2018 of targeting a rally held by supporters of PM Sheikh Hasina, who led opposition at the time
  • The ruling comes as the country suffers political tension after Hasina fled to India in August following a mass uprising that killed hundreds

DHAKA: Bangladesh’s High Court on Sunday acquitted former Prime Minister Khaleda Zia’s son, Tarique Rahman, and overturned a verdict against him over a deadly 2004 grenade attack on a political rally.
The ruling comes at a critical time as the South Asian country suffers political tension after long-time Prime Minister Sheikh Hasina fled the country to India in August following a mass uprising that left hundreds dead. Rahman serves as the acting chairperson of Zia’s Bangladesh Nationalist Party while in self-exile in London, and he could become Bangladesh’s next leader if his party is voted into power.
Rahman and 48 others were found guilty in 2018 in the attack targeting a rally held by supporters of Sheikh Hasina, who led the opposition at the time, leaving two dozen people dead and wounding about 300 others. A court sentenced 19 of them to death while Rahman got life in prison, with Zia’s party accusing the ruling of being politically motivated.
A two-member judge panel scrapped Sunday the entire 2018 ruling for all 49 men, following an appeal lodged by the defendants. Shishir Monir, a defense lawyer, told reporters the court declared the trial and verdict “illegal”.
“As a result, all defendants have been acquitted,” he said.
Zia, who ruled the country as prime minister between 2001-2006, and Hasina are the country’s most powerful politicians and long-time rivals.
Nobel Peace laureate Muhammad Yunus has been chosen as the country’s interim leader since Hasina’s escape, but authorities have been struggling to enforce order amid mob justice, chaos and claims of systematic targeting of minority groups, particularly Hindus, which Yunus said are “exaggerated.”
Hasina’s Awami League party blasted the court ruling in a Facebook post on Sunday, saying it wasn’t “Yunus’ Kangaroo court” and that the people of Bangladesh would be the ones trying those responsible for the attacks.
Zia’s party welcomed Sunday’s ruling.
The attorney general’s office can appeal the ruling in the country’s Supreme Court.
The Yunus-led government has not declared any timeframe for the next election, but Rahman and his party want the new election sometime soon. Meanwhile, Jamaat-e-Islami party, which shared power with Zia’s party in 2001-2006 with important portfolios in the Cabinet, said it wants to allow the Yunus-led government to stay in power to bring in reforms in various sectors before a new election.
Hasina faces charges of crimes against humanity for deaths during the summer’s student-led uprising. The interim government has sought help from Interpol to arrest Hasina. It is not clear if India will respond to any request from Bangladesh for Hasina’s extradition under a mutual treaty.

Pakistan offers support to Malaysia after floods displace over 122,000
  • The number even surpassed the 118,000 evacuated during one of Malaysia’s worst floodings in 2014
  • Both countries agree to encourage the two relief authorities to hold discussions on support from Pakistan

ISLAMABAD: Pakistan’s deputy prime minister and foreign minister, Ishaq Dar, on Sunday telephoned Malaysian Foreign Minister Hajji Mohamad bin Hajji and offered Islamabad’s assistance following the evacuation of more than 122,000 people due to recent floods in Malaysia, the Pakistani foreign ministry said.
The massive floods, caused by relentless rains, swept through Malaysia’s northern states, killing at least four people, according to Malaysian disaster management officials.
The number surpassed the 118,000 evacuated during one of the country’s worst floodings in 2014, and officials feared it could rise further as there was no let-up in torrential downpours.
During the telephonic conversation, Dar offered his deepest sympathies on the tragic loss of lives and property in Malaysia, according to the Pakistani foreign ministry.
“He conveyed Pakistan’s full solidarity with the people of Malaysia and the readiness to extend immediate humanitarian assistance to Malaysia in this difficult time,” the Pakistani ministry said in a statement.
“The two ministers also agreed to encourage the disaster relief authorities of the two countries to continue discussions on humanitarian support from Pakistan.”
Pakistan and Malaysia enjoy a strong bilateral relationship, rooted in shared Islamic values and historical ties.
Since 1957, they’ve fostered economic cooperation, defense collaborations, and cultural exchange. The Pakistan-Malaysia Free Trade Agreement of 2008 boosted trade and investment, while regular high-level visits have solidified their partnership, underpinned by mutual respect and trust.

  • Matiullah Jan was booked in a terrorism and narcotics case after being arrested from outside a hospital in Islamabad
  • Jan thanks his lawyers, journalists and the civil society as well as the diplomatic community for standing by him

ISLAMABAD: A Pakistani journalist, who was arrested after coverage of last week’s anti-government protests in Islamabad, on Sunday denied “fabricated” charges against him, a day after his release in a terrorism and narcotics case.
Matiullah Jan, a broadcaster working with Neo TV, was “picked up” from outside a hospital in Islamabad on Wednesday, where he was investigating alleged fatalities during the recent protests in support of jailed ex-premier Imran Khan, according to his son.
The police report registered against Jan included Code of Criminal Procedure’s Sections 279 (rash driving or riding on a public way), 353 (assault or criminal force to deter public servant from discharge of duty), 382 (theft after preparation made for causing death, hurt or restraint in order to the committing of the theft), 427 (mischief causing damage), 506 (criminal intimidation) along with 7ATA (terrorism-related section) and a narcotics-related section.
On Saturday, an anti-terrorism court judge, Tahir Abbas Sipra, who presided over the hearing of Jan’s bail petition, approved the plea against surety bonds worth Rs10,000 ($36), following which he was released from custody.
“Allah Almighty has been very kind to me once again. I am back home safe and sound,” Jan said on X. “I want to completely deny the false and fabricated charges brought against me by the government.”
Jan has a history of criticizing Pakistan’s government and the country’s powerful military establishment. He was also briefly detained by uniformed men during Imran Khan’s tenure in 2020.
He thanked his lawyers, journalists, politicians, members of the civil society as well as the diplomatic community for standing by him and a timely response to ensure safety and security of journalists in Pakistan.
Successive Pakistan governments have often been criticized by rights monitors for using broad anti-terrorism legislation to quash dissent.
Islamabad witnessed a protest march by Pakistan Tehreek-e-Insaf (PTI) supporters, who faced a major government crackdown in which nearly a thousand political activists were arrested during three days of unrest this week.
Jan was investigating the aftermath of the crackdown on PTI workers when, according to his family, he was taken away by people in unmarked vehicles hours before the police announced his arrest.
Amnesty International has criticized Pakistani security forces for using “unlawful and excessive force” on crowds, but Information Minister Attaullah Tarar told reporters on Wednesday that the PTI was “lying” about it, as its leaders claimed their followers had been killed.
Khan’s party has so far named 12 people, claiming it has evidence they lost their lives during the crackdown in the federal capital and demanding the judiciary take notice and hold top government ministers accountable.

  • Pakistan and Iran have had a history of rocky relations despite a number of commercial agreements
  • In January, both countries came to the brink of war after cross-border strikes on militant hideouts

ISLAMABAD: Pakistan’s deputy prime minister and foreign minister, Ishaq Dar, will leave for Iran today, Monday, on a two-day official visit to attend the 28th meeting of the Economic Cooperation Organization (ECO) Council of Ministers, according to the Pakistani Foreign Office.
Pakistan and Iran have had a history of rocky relations despite a number of commercial pacts. In 2004, both countries signed the $7 billion Iran-Pakistan gas pipeline project agreement but 20 years on, the project remains incomplete.
Tehran has completed the gas pipeline’s construction on its side of the border while Pakistan is seeking a United States (US) waiver to go ahead with it due to international sanctions targeting Iran.
In his address with the ECO meeting in Mashhad, Dar would highlight the potential of greater connectivity in the ECO region, according to Foreign Office spokesperson Mumtaz Zahra Baloch.
“Deputy PM will reiterate Pakistan’s commitment to the ECO charter and highlight the potential of greater connectivity in the ECO region to development of road and rail networks, liberalization of visa regimes, simplification of border procedures and to maintain sustainable growth and enhance geo-economic potential of the ECO region,” Baloch said at a press briefing last week.
“Deputy PM will sign the charter for ECO clean energy center and hold bilateral meetings with participating ministers and other dignitaries on the sidelines.”
Dar would also reiterate Pakistan’s concerns over hostilities in the Middle East that endanger peace and security of the region.
Dar’s visit comes weeks after Iranian FM Seyed Abbas Araghchi’s two-day visit to Islamabad to hold consultations with the Pakistani leadership on the Middle East situation following Israel’s invasion of Gaza and Lebanon, and to discuss bilateral ties with Pakistan.
Despite several agreements between them, Pakistan and Iran have often been at odds over instability along their shared, porous border and routinely trade blame for not rooting out militancy. Tensions surged in January when Pakistan and Iran exchanged airstrikes, both claiming to target alleged militant hideouts in each other’s territory.
Late Iranian president Ebrahim Raisi had later traveled to Pakistan on a three-day visit in April to ease tensions and strengthen bilateral relations. The two sides had also signed memorandums of understanding in the fields of trade, science technology, agriculture, health, culture, and judicial matters.
