Urbanization has led to increased resource exploitation and pollution. Smart cities, by contrast, represent a forward-thinking approach to development, leveraging technology and the latest innovations to address urban challenges.

With 68 percent of the global population expected to live in urban areas by 2050, integrating circular economy concepts is essential for technological, environmental, and economic transformation.

The circular economy framework for innovative cities focuses on reducing resource consumption and promoting the recycling of materials. Urban planning can support this by incorporating reusable construction materials, renewable resources and recycled products.

These efforts can be enhanced by technologies that minimize waste and policies that promote circular resource management.

New technological advancements, including the internet of things, artificial intelligence and blockchain, are key drivers in the development of circular smart cities.

Sensors can monitor waste accumulation, optimize collection schedules and reduce costs, while AI-powered algorithms can predict energy consumption, helping to optimize resource use.

Meanwhile, blockchain enhances transparency and supply chain traceability, promoting sustainable procurement.

A strong example of this is Amsterdam’s Circular City program, which leverages technology to track physical materials and their consumption. Amsterdam’s circular strategy aims to recycle 67 percent of municipal waste with the goal of achieving full circularity by 2050.

Copenhagen has integrated AI into its energy systems, leading to a 42 percent reduction in the city’s carbon emissions over the past decade.

Applying circular economy principles in innovative city development is not just an environmentally responsible choice but an essential one.

Recycling in the Danish capital is commonly implemented within the construction industry, where 80 percent of construction materials are reused or regenerated.

Similarly, Saudi Arabia’s NEOM project envisions a sustainable, smart city that integrates waste-reducing technologies, including renewable energy sources and circular systems.

Circular strategies can lead to significant improvements in waste reduction, energy use and resource utilization. However, obstacles such as high initial costs, bureaucratic constraints, and public skepticism hinder widespread adoption.

Innovations in the circular economy of smart cities require the involvement of governments and the private sector as part of public-private partnerships.

Policymakers must establish clear legal guidelines for sustainability that are easily understood by all stakeholders. This could include mandating the use of recycled materials in construction projects or offering tax exemptions to participants in the circular economy.

Education investment is equally important, as public awareness can drive the behavioral changes necessary for realizing the circular economy.

Additionally, financing is needed for the development of new infrastructure and technologies, such as smart grids, renewable energy sources and modern recycling centers.

Applying circular economy principles in innovative city development is not just an environmentally responsible choice, but an essential one.

With increasing urbanization and growing pressure on the natural environment, circularity can serve as a blueprint for creating sustainable urban environments.

We can build cities for today and tomorrow by advancing technology, fostering teamwork, promoting education and constructing infrastructure.

China’s military drives away Philippine aircraft near Spratly Islands

China’s military drives away Philippine aircraft near Spratly Islands
  • China claims sovereignty over almost the entire South China Sea, a vital waterway for more than $3 trillion of annual ship-borne commerce
  • On Thursday, Philippine guard and fisheries bureau had jointly carried out a maritime domain awareness flight over Spratly Islands

BEIJING: China’s military said it warned and drove away three Philippine aircraft that “illegally intruded” into the airspace near the Spratly Islands on Thursday.
There was no immediate comment from the Philippine embassy in Beijing on the Chinese military’s statement issued on Friday.
China’s Southern Theatre Command accused the Philippine side of attempting to “peddle its illegal claims” through provocation, and warned that the “clumsy maneuver is doomed to failure.”
China claims sovereignty over almost the entire South China Sea, a vital waterway for more than $3 trillion of annual ship-borne commerce, putting it at odds with Brunei, Indonesia, Malaysia, the Philippines, and Vietnam.
A 2016 arbitration ruling invalidated China’s expansive claim but Beijing does not recognize the decision.
On Thursday, the Philippines said its coast guard and fisheries bureau had jointly carried out a maritime domain awareness flight over the Kalayaan Islands, the Philippine name for Spratly Islands.
The mission was to assert the Philippines’ sovereignty, sovereign rights, and maritime jurisdiction in the West Philippine Sea, it said. More than 50 Chinese maritime militia vessels and a Chinese coast guard ship were spotted during the exercise.
It was not immediately clear if that mission, which deployed two aircraft, was the one Chinese military said it responded to.
The latest confrontation comes after Philippine coast guard accused the Chinese navy of performing dangerous flight maneuvers earlier this week when it flew close to a government aircraft patrolling the contested Scarborough Shoal in the South China Sea.
Beijing disputed that account.

  • Riyadh Mayor Prince Faisal bin Abdulaziz bin Ayyaf attends celebration
  • Ties continue to deepen between 2 nations, says envoy Yasunari Morino

RIYADH: The Ambassador of Japan to the Kingdom of Saudi Arabia Yasunari Morino hosted a reception on Thursday to celebrate the 65th birthday of Japan’s Emperor Naruhito.

Prince Faisal bin Abdulaziz bin Ayyaf, mayor of Riyadh region, attended the reception, which included several representatives of diplomatic missions and dignitaries.

In a speech, Morino highlighted the development of relations between Japan and Saudi Arabia, noting that this year marks the 70th anniversary of the establishment of diplomatic ties.

He said several Japanese officials have visited Saudi Arabia this year including Minister of Economy, Trade and Industry Yoji Muto, and Parliamentary Vice Minister for Foreign Affairs Hisashi Matsumoto.

In February, Saudi Arabia’s Foreign Minister Prince Faisal bin Farhan visited Japan and signed a pact with his counterpart to establish a Strategic Partnership Council.

Morino emphasized the expansion of cooperation between the two nations in several sectors including clean energy, mineral resources, technology, health, food, entertainment and sports — in line with the Japan-Saudi Vision 2030 plan.

He also spoke about Japan’s efforts to attract foreign direct investment.

Morino underscored the continued growth of people-to-people exchanges, noting that Japanese culture continues to captivate Saudi Arabia’s citizens, particularly young people.

He also mentioned the upcoming Kansai-Osaka Expo, set to begin in April, and expressed hope the event would attract many visitors from Saudi Arabia and other nations.

He said the expo would showcase the importance of the planet’s ecosystem, human diversity and the collective wisdom of humankind.

Morino reaffirmed his commitment to strengthening Japan-Saudi Arabia strategic partnerships to help promote international peace, stability, and human development.

  • Pressure builds on Volodymyr Zelensky to sign away precious mineral rights in exchange for Washington’s help defending against Russia
  • Tensions between Trump and Zelensky over the proposed mineral deal and Washington’s outreach to Moscow have exploded this week

KYIV: The US national security adviser warned Ukraine’s leader to stop hurling “insults” at Donald Trump, as pressure built Friday on Volodymyr Zelensky to sign away precious mineral rights in exchange for Washington’s help defending against Russia.
Tensions between Trump and Zelensky over the proposed mineral deal — which Kyiv has rejected — and Washington’s outreach to Moscow have exploded this week in a series of barbs traded at press conferences and on social media.
Zelensky has warned that Trump has succumbed to Russian “disinformation,” while the US leader has accused his counterpart of starting the war and branded him a “dictator without elections.”
“Some of the rhetoric coming out of Kyiv, frankly, and insults to President Trump were unacceptable,” US national security adviser Mike Waltz told a Thursday briefing at the White House.
“President Trump is obviously very frustrated right now with President Zelensky, the fact that he hasn’t come to the table, that he hasn’t been willing to take this opportunity that we have offered,” he said.
The United States is a vital financial and military supporter of Ukraine, but Trump has rattled Kyiv and its European backers by opening talks with Moscow they fear could end the war on terms that reward Russian President Vladimir Putin.
The spat has turned personal with Trump falsely claiming Zelensky is hugely unpopular among his own people and the Ukrainian leader saying Trump lives in a Russian “disinformation space.”
Tech tycoon and Trump backer Elon Musk weighed in Thursday, saying Ukrainians “despised” their president and that the US leader was right to leave him out of talks with Russia.
Amid the war of words, Zelensky said Thursday he had held a “productive meeting” with US envoy Keith Kellogg in Kyiv.
“We had a detailed conversation about the battlefield situation, how to return our prisoners of war, and effective security guarantees,” Zelensky said on social media after the meeting.
“Strong Ukraine-US relations benefit the entire world,” he added.
However, there was no joint press conference or statements after the discussions, as would typically accompany such a visit.
Trump is calling for Kyiv to hand over access to its mineral wealth as compensation for tens of billions of dollars in US aid delivered under his predecessor Joe Biden.
Zelensky rejected a deal proposed by Trump as it did not include “security guarantees” — Kyiv’s key demand from its Western backers in any agreement with Russia to halt the fighting.
The feud marks a dramatic reversal from US policy under Biden, who lauded Zelensky as a hero, shipped vast supplies of arms to Kyiv and hammered Moscow with sanctions.
Trump has instead criticized Zelensky and blamed him for starting the war that began with Russia’s full-scale invasion three years ago.
“A Dictator without Elections, Zelensky better move fast or he is not going to have a Country left,” he wrote on his Truth Social platform on Wednesday.
Zelensky was elected in 2019 for a five-year term and has remained leader in line with Ukrainian rules under martial law, imposed as his country fights for its survival.
While Zelensky’s popularity has fallen, the percentage of Ukrainians who trust him has never dipped below 50 percent since the conflict started, according to the Kyiv International Institute of Sociology (KIIS).
Trump’s invective drew shock reactions from Europe.
German Chancellor Olaf Scholz said it was “wrong and dangerous” to call Zelensky a dictator.
The White House said France’s Emmanuel Macron and Britain’s Keir Starmer will visit Trump next week after European leaders held emergency summits in recent days over how to deal with Trump’s threats to overhaul decades of transatlantic security ties.
The Kremlin, buoyed by its rapprochement with Washington, has hailed Trump’s comments.
Russia, which for years has railed against the US military presence in Europe, wants a reorganization of the continent’s security framework as part of any deal to end the Ukraine fighting.
Putin said Wednesday that US allies “only have themselves to blame for what’s happening,” suggesting they were paying the price for opposing Trump’s return to the White House.
Neither Kyiv nor European countries were invited to high-level talks between top diplomats from Russia and the US in Saudi Arabia earlier this week, deepening fears they are being sidelined.

Survivors of past air disasters offer support after Toronto crash

Survivors of past air disasters offer support after Toronto crash
  • Survivors of past aviation accidents are offering advice and support to the 80 passengers and crew members of the plane that crashed and flipped over in Toronto
  • The National Air Disaster Alliance was created in 1995 to support survivors and victims’ families and advocate for safety improvements

CONCORD: Sad. Happy. Anguished. Guilty.
Denise Lockie of Charlotte, North Carolina, has felt all of the above in recent weeks, as a string of major aviation accidents brought back memories of crash-landing in an icy river in New York. Sixteen years after the “Miracle on the Hudson,” she and other aviation disaster survivors stand ready to support those who are just emerging from their ordeal in Toronto on Monday.
“Right now, they haven’t even processed what has happened,” Lockie said of the 80 passengers and crew members who survived when Delta Air Lines flight 4819 crashed and flipped over at Pearson International Airport.
There were no survivors when a commercial jetliner and an Army helicopter collided in Washington, D.C., on Jan. 29, a medical transportation plane crashed in Philadelphia on Jan. 31 and a plane carrying 10 people crashed in Alaska on Feb. 6. But in Toronto, not only did no one die, the last of the injured were released from the hospital Thursday.
“It’s amazing,” said passenger Peter Carlson, who spoke at a conference less than 48 hours after the crash. Though he managed to crack a joke — “Nothing beats a good road trip besides an airplane crash” — he later admitted struggling to leave his hotel room.
“I was quite emotional about this whole thing and just really want to be home,” said Carlson, the newest member of what retired flight attendant Sandy Purl calls a “sad sorority and fraternity.”
A history of survival
Monday’s crash in Toronto wasn’t the first time lives were spared during a major aviation disaster there: In 2005, all 309 people on board Air France Flight 358 survived after it overran the runway and burst into flames.
In 1989, 184 of the 296 people aboard United Airlines Flight 232 survived a crash in Sioux City, Iowa. And in 1977, Purl was one of 22 survivors when Southern Airways Flight 242 lost both engines in a hailstorm and crashed in New Hope, Georgia. Sixty-three people aboard the plane died, along with nine on the ground.
“Immediately you have a euphoria because you survived,” said Purl, now 72. “But then you go into what’s known as psychic numbing, which protects you from everything that’s in your brain that you can’t bring to the surface for a long time down the road, if ever.”
For more than a year after the crash, Purl’s strategy was to flee whenever anyone mentioned the disaster. Eventually she was admitted to a psychiatric hospital where she told the staff, “I can’t stop crying.”
A kindly doctor took her hand and reassured her what she was feeling was real.
“For the first time, a year and a half later, people weren’t saying, ‘You look so good! Get on with your life, you’re so lucky to be alive,’” she said. “For the first time, someone gave me permission to feel and to cry and to feel safe.”
Survivors stick together
Both Purl and Lockie are members of the National Air Disaster Alliance, which was created in 1995 to support survivors and victims’ families and advocate for safety improvements.
In 2009, the group published an open letter to the 155 passengers and crew members of US Airways flight 1549 after Captain Chesley “Sully” Sullenberger famously landed the plane in the Hudson River after a bird strike disabled both engines.
“We are grateful and thankful that all survived, but survivors need time to process and comprehend what it means to be an air crash survivor,” the group wrote, encouraging survivors to rest, retreat, rely on others and reserve their rights to privacy.
Paying it forward, Lockie is offering similar advice to those aboard the Toronto flight. She described being in a fog for about eight weeks after her crash, struggling to keep up with her corporate job as her injuries healed and being beset by nightmares and panic attacks.
“Absolutely number one as far as I’m concerned is taking to somebody who can understand,” she said. “I think Delta is a fantastic airline and I’m sure their care team is fantastic, but then again, how many people on those care teams have actually been involved in an aviation incident?”
Friends and family might urge survivors to move on with their lives, she said, but “it just doesn’t work that way.”
“You might have fears that come out later on, and you really have to be able to deal with those,” she said. “So my recommendation is to take all the help you can possibly take.”
It doesn’t take much to trigger memories
While Lockie said her experience hasn’t deterred her from flying often, it has shaped her behavior in other ways. When she enters a store or restaurant, for example, she always checks for the fastest way out.
“You have to be able to calm yourself if there’s something that triggers your emotional aptitude,” she said.
Purl, who returned to work as a flight attendant four years after the crash, said she can be triggered by the smell of gasoline or seeing news footage of other crashes.
“I look at the TV and I see my crash,” she said. “I smell it. I taste it. I see the black smoke and I can’t get through it. I feel the heat of the fire.”
The Toronto survivors may find their experience exacerbates underlying traumas, she said.
“Like the layers of an onion, you pull one back and there’s another layer underneath,” she said.
Her advice: Live one day at a time, seek out people who offer unconditional love and talk, talk, talk.
“And then find a way to make a difference as a result,” she said.

Luigi Mangione set for first court appearance since his arraignment in UnitedHealthcare CEO’s death
  • The 26-year-old has pleaded not guilty to multiple counts of murder, including murder as an act of terrorism, in the Dec. 4 killing of Brian Thompson

NEW YORK: The man accused of fatally shooting the CEO of UnitedHealthcare in New York City and leading authorities on a five-day manhunt is scheduled to be in court Friday for the first time since his December arraignment on state murder and terror charges.
Luigi Mangione, 26, is set for a hearing in state court in Manhattan. Prosecutors and Mangione’s defense lawyers are expected to provide updates on the status of the case and Judge Gregory Carro could set deadlines for pretrial paperwork and possibly even a trial date.
Mangione has pleaded not guilty to multiple counts of murder, including murder as an act of terrorism, in the Dec. 4 killing of Brian Thompson outside a midtown Manhattan hotel. The executive was ambushed and shot on a sidewalk as he walked to an investor conference.
Mangione also faces federal charges that could carry the possibility of the death penalty. He is being held in a Brooklyn federal jail alongside several other high-profile defendants, including Sean “Diddy” Combs and Sam Bankman-Fried.
Prosecutors have said the two cases will proceed on parallel tracks, with the state charges expected to go to trial first. The maximum sentence for the state charges is life in prison without parole. A Feb. 24 hearing in Pennsylvania on charges of possessing an unlicensed firearm, forgery and providing false identification to police was canceled.
In a statement posted on a website for his legal defense, Mangione said: “I am overwhelmed by — and grateful for — everyone who has written me to share their stories and express their support. Powerfully, this support has transcended political, racial, and even class divisions.”
Mangione was arrested in a Pennsylvania McDonald’s on Dec. 9. Police said he was carrying a gun that matched the one used in the shooting and a fake ID. He also was carrying a notebook expressing hostility toward the health insurance industry and especially wealthy executives, authorities said.
Defense lawyer Karen Friedman Agnifilo argued at his Dec. 23 arraignment that “warring jurisdictions” had turned Mangione into a “human ping-pong ball.”
She accused New York City Mayor Eric Adams and other government officials of tainting the jury pool by bringing Mangione back to Manhattan in a choreographed spectacle involving heavily armed officers escorting him up a pier from a heliport.
Friedman Agnifilo singled out Adams’ comment on a local TV station that he wanted to be there to look “him in the eye and say, ‘you carried out this terroristic act in my city.’”
