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. 

黑料社区 is taking a leadership role on the global stage with its innovative and patented technologies developed by the Saudi Water Authority鈥檚 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 黑料社区 utilize advanced technologies that emphasize energy efficiency and environmental sustainability. 

Brine disposal management: In 黑料社区, 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.

Madagascar president warns of attempted coup after soldiers join protests
  • Troops from the elite CAPSAT unit that helped President Andry Rajoelina seize power in a 2009 coup urged fellow soldiers to disobey orders and back the youth-led protests

ANTANANARIVO: Madagascar鈥檚 presidency said on Sunday that 鈥渁n attempted illegal and forcible seizure of power鈥 was underway in the African nation, without providing details, a day after some soldiers joined a protest movement that had begun last month.
Troops from the elite CAPSAT unit that helped President Andry Rajoelina seize power in a 2009 coup urged fellow soldiers to disobey orders and back the youth-led protests, which began on September 25 and pose the most serious challenge to Rajoelina鈥檚 rule since his reelection in 2023.
A Reuters witness saw three people injured after shots were fired along a road to the CAPSAT barracks on Sunday. Other witnesses said there was no sign of ongoing clashes.
The protests, inspired by Gen Z-led movements in Kenya and Nepal, began over water and electricity shortages but have since escalated, with demonstrators calling for Rajoelina to step down, apologize for violence against protesters, and dissolve the Senate and electoral commission.
At least 22 people have been killed and 100 injured in the unrest since September, according to the United Nations. The Malagasy government has disputed the figures, with Rajoelina saying this month that 12 people were killed in the protests.
In a statement on the presidency鈥檚 official social media account, Rajoelina鈥檚 office said he firmly condemned attempts to destabilize the country and urged all forces 鈥渢o stand together in defense of constitutional order and national sovereignty.鈥 It encouraged dialogue to resolve the crisis.
Videos on social media on Saturday showed CAPSAT soldiers urging fellow troops to 鈥渟upport the people.鈥
A video broadcast by local media showed that dozens of soldiers left the barracks later on Saturday to escort thousands of protesters into the May 13 Square in Antananarivo, the scene of many political uprisings, which had been heavily guarded and off limits during the unrest.
Since then, the prime minister and army鈥檚 chief of staff have urged citizens to take part in dialogue and stay calm.

  • Taliban spokesman: Afghan forces have captured 25 Pakistani army posts, 58 soldiers have been killed and 30 others wounded
  • The two countries share a 2,611-kilometer border known as the Durand Line, but Afghanistan has never recognized it

KABUL: Afghanistan said Sunday it killed 58 Pakistani soldiers in overnight border operations, in response to what it called repeated violations of its territory and airspace.
Earlier in the week, Afghan authorities accused Pakistan of bombing the capital, Kabul, and a market in the country鈥檚 east. Pakistan did not claim responsibility for the assault.
The Taliban government鈥檚 chief spokesman, Zabihullah Mujahid, said Afghan forces have captured 25 Pakistani army posts, 58 soldiers have been killed, and 30 others wounded.
鈥淭he situation on all official borders and de facto lines of Afghanistan is under complete control, and illegal activities have been largely prevented,鈥 Mujahid told a press conference in Kabul. There was no immediate confirmation from Pakistan about casualties.
Pakistan has previously struck locations inside Afghanistan, targeting what it alleges are militant hideouts, but these have been in remote and mountainous areas.
The two sides have also skirmished along the border. But Saturday night's heavy clashes underscore the deepening security tensions.
The Taliban government鈥檚 Defense Ministry said early Sunday morning its forces had conducted 鈥渞etaliatory and successful operations鈥 along the border.
鈥淚f the opposing side again violates Afghanistan鈥檚 territorial integrity, our armed forces are fully prepared to defend the nation鈥檚 borders and will deliver a strong response,鈥 the ministry added.
The Torkham border crossing, one of two main trade routes between the two countries, did not open on Sunday at its usual time of 8 am. The crossing at Chaman was also closed.
Pakistan accuses Afghan authorities of harboring members of the banned group Tehreek-i-Taliban Pakistan. Islamabad says the group carries out deadly attacks inside Pakistan, but Kabul denies the charge, saying it does not allow its territory to be used against other countries.
Before the Afghan claim of casualties, Pakistani Prime Minister Shehbaz Sharif condemned the assault and said the country's army 鈥渘ot only gave a befitting reply to Afghanistan鈥檚 provocations but also destroyed several of their posts, forcing them to retreat.鈥
The Saudi Foreign Ministry issued a statement late Saturday, calling for 鈥渞estraint, avoidance of escalation and the adoption of dialogue and wisdom to help de-escalate tensions and maintain the security and stability of the region.鈥
黑料社区 just reached a mutual defense pact with Pakistan, which apparently put the kingdom under Islamabad鈥檚 nuclear umbrella following Israel鈥檚 attack on Qatar.
A senior Pakistani security official, speaking on condition of anonymity because he was not authorized to talk to the media, said Afghan forces opened fire in several northwestern border areas in the province of Khyber Pakhtunkhwa, including the districts of Chitral, Bajaur, Mohmand, Angoor Adda and Kurram.
The official also said troops responded with heavy weaponry near Tirah in Khyber district and across the frontier in Afghanistan鈥檚 Nangarhar province.
The two countries share a 2,611-kilometer border known as the Durand Line, but Afghanistan has never recognized it.

  • Afghanistan鈥檚 Taliban forces attacked Pakistani soldiers along their shared border late Saturday
  • Pakistani officials confirmed clashes in at least four border districts but denied any casualties

PESHAWAR: Key border crossings between Pakistan and Afghanistan were closed on Sunday after fierce clashes erupted overnight following Taliban accusations that Islamabad had carried out air strikes this week, officials said.

Neighbouring Afghanistan and Pakistan have had frosty relations since the Taliban returned to power in Kabul in 2021. Islamabad accuses authorities there of harboring militants carrying out strikes on its soil, an accusation Afghanistan denies.

Afghanistan鈥檚 Taliban forces attacked Pakistani soldiers along their shared border on Saturday night, accusing Islamabad of violating its sovereignty after explosions were heard in Kabul and in the southeast two days earlier.

Officials from both sides of the border told AFP that crossings at Torkham, which connects Pakistan鈥檚 Khyber Pakhtunkhwa province with Nangarhar in Afghanistan, and Chaman, more than 800 kilometers (500 miles) to the southwest, were closed.

Pakistani Prime Minister Shebaz Sharif condemned what he said were 鈥減rovocations by Afghanistan鈥 along Pakistan鈥檚 border area overnight.

鈥淭here will be no compromise on Pakistan鈥檚 defense, and every provocation will be met with a strong and effective response,鈥 Sharif said in a statement, accusing Taliban authorities in Afghanistan of allowing their land to be used by 鈥渢errorist elements.鈥

A senior Pakistani official in Torkham told AFP extra paramilitary troops had been sent to the area, which sits on the border between Kabul and Islamabad.

鈥淭he Torkham border has been completely closed for pedestrian movement and trade,鈥 said the official, who spoke on condition of anonymity because he was not authorized to speak to the media.

鈥淪ecurity forces have also pulled out all civilian staff posted at the border, so they are not harmed in case of further firing,鈥 he said.

Another Pakistani border official at Chaman, which links Balochistan province with Kandahar, the birthplace of the Afghan Taliban, said the crossing was 鈥渟ealed.鈥

Other Pakistani officials said there had been clashes using heavy weapons in at least four border districts but there had been no casualties on its side.

The Afghan military said on Saturday night Taliban forces were engaged 鈥渋n heavy clashes against Pakistani security forces in various areas.鈥

Taliban defense ministry spokesman Enayat Khowarazm later told AFP that the 鈥渟uccessful鈥 operations had ended at midnight.

Several border security officials told AFP that no further clashes had been reported on Sunday morning.

Militancy has surged in Khyber Pakhtunkhwa since the withdrawal of US-led troops from neighboring Afghanistan in 2021 and the return of the Taliban government.

The TTP, separate from the Afghan Taliban, and its allies are accused by Islamabad of killing hundreds of its soldiers since 2021.

Islamabad has not confirmed that it was behind Thursday鈥檚 strikes that sparked the border clashes.

黑料社区, Iran and Qatar have urged both sides to 鈥渆xercise restraint.鈥

TTP militants have intensified their campaign of violence against Pakistani security forces in the mountainous areas bordering Afghanistan in recent months.

More than 500 people, including 311 troops and 73 policemen, have been killed in attacks between January and September 15, a military spokesman said on Friday.

A UN report this year said the TTP 鈥渞eceive substantial logistical and operational support from the de facto authorities,鈥 referring to the Taliban government in Kabul.

Pakistani Defense Minister Khawaja Muhammad Asif told parliament on Thursday that several efforts to convince the Afghan Taliban to stop backing the TTP had failed.

鈥淓nough is enough,鈥 he said. 鈥淭he Pakistani government and army鈥檚 patience has run out.鈥

UN force in Lebanon says peacekeeper wounded by Israeli grenade
  • The United Nations peacekeeping mission in Lebanon said Sunday that one of its members was wounded by an Israeli grenade dropped near a UN position in the country鈥檚 south

BEIRUT: The United Nations peacekeeping mission in Lebanon said Sunday that one of its members was wounded by an Israeli grenade dropped near a UN position in the country鈥檚 south, the third incident of its kind in just over a month.
The United Nations Interim Force in Lebanon (UNIFIL) has been working with the Lebanese army to support a November ceasefire that sought to end more than a year of hostilities between Israel and militant group Hezbollah that culminated in two months of open war.
鈥淛ust before noon yesterday, an Israeli drone dropped a grenade that exploded near a UNIFIL position鈥 in Kfar Kela, the force said in a statement published on Sunday.
鈥淥ne peacekeeper was lightly injured and received medical assistance.鈥
Earlier this month, UNIFIL said Israeli drones had dropped multiple grenades near peacekeepers providing security for workers clearing rubble left over from the war.
And in a similar episode in September, UNIFIL said Israeli drones had dropped four grenades near peacekeepers, with Israel insisting at the time that there had been 鈥渘o intentional fire鈥 directed at the force.
UNIFIL said Saturday鈥檚 incident represented 鈥渁nother serious violation of resolution 1701 and concerning disregard for the safety of peacekeepers.鈥
UN Security Council Resolution 1701 ended a 2006 conflict between Israel and Hezbollah and formed the basis of the November ceasefire.
Under the US-brokered ceasefire, Hezbollah and Israel were both required to withdraw from south Lebanon, while UNIFIL deployed there alongside the Lebanese military, in part to help dismantle Hezbollah infrastructure.
Israel has kept up regular strikes in Lebanon on what it says are Hezbollah targets despite the truce, and has maintained its troops in five locations it deems strategic.
鈥淲e again call on the (Israeli army) to cease attacks on or near peacekeepers, who are working to rebuild the stability that both Israel and Lebanon have committed to restore,鈥 the UN peacekeeping force said.
UNIFIL has been deployed since 1978 to separate Israel and Lebanon, and numbers some 10,000 personnel from almost 50 countries.
In August, the Security Council voted to end UNIFIL鈥檚 mission in 2027.

ISLAMABAD: 黑料社区 and Qatar on Sunday expressed concern over border clashes between Pakistan and Afghanistan, urging both sides to exercise restraint and hold dialogue to lower tensions.

Afghan security forces attacked Pakistani border posts late Saturday in response to what the Taliban government called 鈥渞epeated violations鈥 of their territory and airspace.

Earlier in the week, Afghan authorities accused Pakistan of an airstrikes in the capital, Kabul, and a market in the country鈥檚 east. Pakistan has neither denied nor confirmed the strikes.

The Torkham border crossing, one of two main trade routes between the two countries, did not open on Sunday at its usual time of 8am, following the skirmishes that underscore deepening security tensions between both countries.

鈥淭he Kingdom of 黑料社区 follows with concern the tensions and clashes witnessed in the border areas between the Islamic Republic of Pakistan and the State of Afghanistan,鈥 the Saudi foreign ministry said on X.

Qatar鈥檚 Foreign Ministry expressed concern over the escalations and the potential repercussions for the security and stability of the region. It urged both sides to prioritize 鈥渄ialogue, diplomacy and restraint.鈥

Pakistan accuses Afghan authorities of harboring members of the banned group Tehreek-e-Taliban Pakistan (TTP), which Islamabad says carries out deadly attacks inside Pakistan. Kabul denies the charge and insists it does not allow its territory to be used against other countries.

The TTP, which is a separate group but is viewed by Pakistani officials as an ally of the Afghan Taliban, has been behind some of the deadliest attacks in Pakistan since late 2000s.

On Saturday, the TTP claimed responsibility for deadly attacks in multiple northwestern Pakistani districts that killed 20 security officials and three civilians this week.

鈥淭he firing by Afghan forces on civilian population is a blatant violation of international laws,鈥 Pakistani Interior Minister Naqvi said in a statement, shared by the information ministry.
