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.

  • Task force set up in 2009 in response to piracy attacks in Gulf of Aden, off eastern coast of Somalia
  • Pakistan has held command of CTF-151 a record 11 times followed by Turkiye which has led it 7 times

KARACHI: Pakistan Navy has taken over command for the eleventh time of the Combined Task Force-151 (CTF-151), a multinational body set up in 2009 as a response to piracy attacks in the Gulf of Aden and off the eastern coast of Somalia, the navy’s media wing said on Thursday. 
CTF-151’s mission is to disrupt piracy and armed robbery at sea and engage with regional and other partners to build capacity and improve relevant capabilities in order to protect global maritime commerce and secure freedom of navigation. It operates in conjunction with the EU’s Operation Atalanta and NATO’s Operation Ocean Shield.
“Change of Command ceremony held at Combined Maritime Forces Headquarters, Bahrain,” the Pakistan navy said in a statement. “Commodore Sohail Ahmed Uzmi of Pakistan Navy appointed as new Commander of Combined Task Force-151.”
Earlier, the command was held by the Turkish Navy. Pakistan has held the command of the CTF-151 force a record 11 times followed by Turkiye, which has led it 7 times. 
“Pakistan Navy will continue to work with navies of other countries for peace and stability in the region,” the statement quoted Uzmi as saying. 
Command of CTF 151 is rotated between participating nations on a three-to-six-monthly basis. Countries that have led CTF 151 include Bahrain, Brazil, Denmark, Japan, Jordan, Kuwait, Pakistan, the Philippines, New Zealand, Republic of Korea, Singapore, Thailand, Türkiye, the UK, and the US. A variety of countries assign vessels, aircraft, and personnel to the task force.

Pakistan arrests suspected human smuggler behind Morocco migrant boat tragedy

Pakistan arrests suspected human smuggler behind Morocco migrant boat tragedy
  • Boat capsized near Morocco’s coast on Jan. 15 while carrying 86 migrants including 66 Pakistanis
  • Moroccan authorities have said 36 people were rescued, survivors include 22 Pakistanis

ISLAMABAD: Pakistan’s Federal Investigation Agency (FIA) said on Thursday it had arrested a human trafficker suspected of illegally sending Pakistanis to Spain on a migrant boat that capsized off the coast of Morocco last week.
The boat capsized near Morocco’s coast on Jan. 15 while carrying 86 migrants, including 66 Pakistanis, according to migrant rights group Walking Borders. Moroccan authorities said a day later 36 people were rescued from the vessel which left Mauritania on Jan. 2, while the Pakistani Foreign Office has said the survivors include 22 Pakistanis.
The tragedy has once again underscored the perilous journeys many migrants, including Pakistanis, embark on due to conflict and economic instability in their home countries.
“Human smuggler involved in Moroccan boat accident arrested,” the FIA said in a statement, identifying the suspect as Muhammad Aslam and saying he was arrested after a raid in the small town of Sambrial in Pakistan’s Punjab province.

The statement said Aslam and his accomplices had taken Rs5.35 million from the family of Aamir Ali, who died in the boat accident, and had tried to smuggle him to Spain via Mauritania.
“A case has been registered against the accused and an investigation has been launched. More arrests are expected after the accused are identified,” the FIA said.

A record 10,457 migrants, or 30 people a day, died trying to reach Spain in 2024, most while attempting to cross the Atlantic route from West African countries such as Mauritania and Senegal to the Canary islands, according to Walking Borders.
In 2023, hundreds of migrants, including 262 Pakistanis, drowned when an overcrowded vessel sank in international waters off the southwestern Greek town of Pylos, marking one of the deadliest boat disasters ever recorded in the Mediterranean Sea. More recently, five Pakistani nationals died in a shipwreck off the southern Greek island of Gavdos on Dec. 14.

The Pakistani government has ramped up efforts in recent months to combat human smugglers facilitating dangerous journeys for illegal immigrants to Europe, resulting in several arrests.
Prime Minister Shehbaz Sharif has also urged increased collaboration with international agencies like Interpol to ensure swift action against human trafficking networks.
