The U.N. said this month that the world’s population reached 8 billion people, and more than half of the population growth up to 2050 would come from eight countries, five of them in Africa. In that time span, Nigeria is expected to double its population to 400 million people to become the world’s third most populous nation. Experts warn that without proper planning, such growth would be unsustainable, as Timothy Obiezu reports from Abuja, Nigeria. Videographer: Emeka Gibson

Prayer. Bombs. Walls. Over the decades, people have tried all of them to stanch the flow of lava from Hawaii’s volcanoes as it lumbered toward roads, homes and infrastructure.

Now Mauna Loa — the world’s largest active volcano — is erupting again, and lava is slowly approaching a major thoroughfare connecting the Big Island’s east and west sides. And once more, people are asking if anything can be done to stop or divert the flow.

“It comes up every time there’s an eruption and there’s lava heading towards habited areas or highways,” said Scott Rowland, a geologist at the University of Hawaii. “Some people say, ‘Build a wall’ or ‘Board up,’ and other people say, ‘No, don’t!”

Humans have rarely had much success stopping lava and, despite the world’s technological advances, doing so is still difficult and dependent on the force of the flow and the terrain. But many in Hawaii also question the wisdom of interfering with nature and Pele, the Hawaiian deity of volcanoes and fire.

Prayers to Pele

Attempts to divert lava have a long history in Hawaii.

In 1881, the governor of Hawaii Island declared a day of prayer to stop lava from Mauna Loa as it headed for Hilo. The lava kept coming.

According to the U.S. Geological Survey, Princess Regent Lili’uokalani and her department heads went to Hilo and considered ways to save the town. They developed plans to build barriers to divert the flow and place dynamite along a lava tube to drain the molten rock supply.

Princess Ruth Ke’elikōlani approached the flow, offered brandy and red scarves and chanted, asking Pele to stop the flow and go home. The flow stopped before the barriers were built.

More than 50 years later, Thomas A. Jaggar, the founder of the Hawaiian Volcano Observatory, asked U.S. Army Air Services to send planes to bomb a Mauna Loa vent to disrupt lava channels.

Lt. Col. George S. Patton, who later became famous as a general in Europe during World War II, directed planes to drop 20 272-kilogram demolition bombs, according to a National Park Service account of the campaign. The bombs each had 161 kilograms of TNT. The planes also dropped 20 smaller bombs that only had black powder charge.

Jagger said the bombing helped to “hasten the end of the flow,” but Howard Stearns, a U.S. Geological Survey geologist onboard the last bombing run, was doubtful. In his 1983 autobiography, he wrote: “I am sure it was a coincidence.”

According to the park service, geologists today also are doubtful the bombing stopped the lava flow, which didn’t end with the bombing. Instead, the flows waned over the next few days and didn’t change paths.

Local advises to go with the flow

Rowland said authorities could use a bulldozer to pile a big berm of broken rock in front of Daniel K. Inouye Highway. If the terrain is flat, then lava would pile up behind the wall. But the lava may flow over it, like it did when something similar was attempted in Kapoho town in 1960.

Rapidly moving lava flows, like those from Kilauea volcano in 2018, would be more difficult to stop, he said.

“It would have been really hard to build the walls fast enough for them. And they were heading towards groups of homes. And so you would perhaps be sacrificing some homes for others, which would just be a legal mess,” he said.

He said he believes most people in Hawaii wouldn’t want to build a wall to protect the highway because it would “mess with Pele.”

If lava crosses the highway, Rowland said officials could rebuild that section of the road like they did in 2018 when different routes were covered. There are no current plans to try to divert the flow, a county official said.

Thinking you should physically divert lava is a Western idea rooted in the notion that humans have to control everything, said Kealoha Pisciotta, a Native Hawaiian cultural practitioner. She said people need to adjust to the lava, not the other way around.

Britain’s Prince William capped a three-day visit to Boston by meeting with U.S. President Joe Biden on Friday, ahead of announcing his Earthshot Prize environmental award winners at a gala event.

The Prince of Wales shook hands with Biden and spoke quietly in the winter cold near the water outside of the John F. Kennedy Memorial Library and Museum. He also met Caroline Kennedy, the late president’s daughter, and told her that the stories of the Earthshot Prize winners were an inspiration.

William once again paid homage to President Kennedy, “the man who inspired our mission,” and said the “game-changing” solutions were being offered to protect the planet.

Kennedy’s legacy loomed large during the visit by William and his wife, Kate. William named his environmental award the Earthshot Prize, drawing inspiration from Kennedy’s moonshot speech that mobilized the nation in 1962 by declaring astronauts would set foot on the moon before decade’s end.

William became heir apparent less than three months ago with his grandmother’s death, but he was already crowned Britain’s chief environmentalist.

During his visit to Boston, William drew praise for his drawing attention to pollution and climate change and the need to scale up solutions to address them. Those efforts were culminating Friday evening, when the five winners of the royal couple’s Earthshot Prize for environmental innovators were to be announced.

“I just appreciate that they are using platform and publicity to bring attention to meaningful climate work,” said Joe Christo, who is managing director of Stone Living Lab, which researches nature-based approaches to climate adaptation, and was among those who met the royal couple at Boston Harbor on Thursday.

“I do know his dad is a big environmentalist,” he said. “He seems to be doing a great job continuing that legacy.”

The Earthshot Prize offers 1 million pounds ($1.2 million) in prize money to each of the winners of five separate categories: nature protection, clean air, ocean revival, waste elimination, and climate change. The winners and all 15 finalists also receive help in expanding their projects to meet global demand.

The winners were to be announced at Boston’s MGM Music Hall as part of a glitzy show headlined by Billie Eilish, Annie Lennox, Ellie Goulding, and Chloe x Halle. The show will also feature videos narrated by naturalist David Attenborough and actor Cate Blanchett.

William is following in the footsteps of his environmentally minded grandfather Prince Philip — the late husband of Queen Elizabeth II — and more recently his father and Elizabeth’s successor, King Charles III.

In his capacity as prince, Charles was for decades one of Britain’s most prominent environmental voices, blasting the ills of pollution. Last year, he stood before world leaders at a U.N. climate conference in Scotland and suggested the threats posed by climate change and biodiversity loss were no different than those posed by the coronavirus pandemic.

But now that he is king, Charles is expected to be more careful with his words and must stay out of politics and government policy, in accordance with the traditions of Britain’s constitutional monarchy. This year, he did not attend the U.N. climate conference in Egypt.

The caution presents an opportunity for William to step into that role as the royal family’s environmental advocate and speak more forcefully about the issues once associated with his father.

There is no better example than the Earthshot Prize.

“It’s a huge deal to Prince William,” Joe Little, the managing editor of Majesty Magazine. “He knows he can attract attention from the most important people. That really is the core of the Boston trip.”

After attending a welcome event Wednesday at City Hall and then a Boston Celtics game, the royal couple spent much of Thursday hearing about the threats of climate change and solutions in the works.

They got a firsthand look at some innovations at a green technology startup incubator called Greentown Labs, in Somerville. Among them were solar-powered autonomous boats and low-carbon cement.

“Climate change is a global problem, so it’s so important to have global leaders talking about the importance of taking action,” said Lara Cottingham, vice president of strategy policy and climate impact for Greentown Labs.

William and Kate also chatted with Katherine Dafforn, co-founder of Living Seawalls, an Australian company that designs environmentally friendly ocean infrastructure. “For all of us, time is ticking,” William said.

The couple’s first trip to the U.S. since 2014 is part of the royal family’s efforts to change its international image. After Elizabeth’s death, Charles has made clear that his will be a slimmed-down monarchy, with less pomp and ceremony than its predecessors. William and Kate arrived in Boston on a commercial British Airways flight.

The lava flowing from Hawaii’s Mauna Loa, which is the world’s largest active volcano and erupted this week, is edging closer to the Big Island’s main highway.

The U.S. Geological Survey’s Hawaiian Volcano Observatory reported Friday that the main front of the lava flow was 5.2 kilometers away from the Daniel K. Inouye Highway, also known as Saddle Road, and could possibly reach it in a week.

But the USGS also said that because of the unpredictable nature of lava flows, it’s “difficult to estimate when or if the flow will impact” the highway, which is the island’s main east-west road.

If the main highway is cut off, Hawaii county officials say, traffic will be forced onto coastal roads, crowding them and adding hours onto a trip from Hilo, the largest city on the Big Island, to Kona, a tourist magnet, which takes just 90 minutes on the Daniel K. Inouye Highway.

Talmadge Magno, administrator of Hawaii County’s Civil Defense Agency, told reporters this week that if lava flows onto the highway it would likely take the federal government a few months to get it passable again once the flows halt.

After the eruption on Sunday, the lava initially moved quickly down steep slopes. Over the past day, it reached a flatter area and slowed significantly, moving at just 40 meters per hour. The sight has attracted visitors to the “once in a lifetime” spectacle.

The USGS says many variables influence exactly where the lava will move and at what speed. On flatter ground, lava flows spread out and “inflate” — creating individual lobes that can advance quickly and then stall.

Mauna Loa rises 4,169 meters above the Pacific Ocean, part of a chain of volcanoes that formed the islands of Hawaii. It last erupted in 1984.

With Ukraine scrambling to keep communication lines open during the war, an army of engineers from the country’s phone companies has mobilized to help the public and policymakers stay in touch during repeated Russian missile and drone strikes.

The engineers, who typically go unseen and unsung in peacetime, often work around the clock to maintain or restore phone service, sometimes braving minefields to do so. After Russian strikes took out the electricity that cellphone towers usually run on, they revved up generators to keep the towers on.

“I know our guys – my colleagues – are very exhausted, but they’re motivated by the fact that we are doing an important thing,” Yuriy Dugnist, an engineer with Ukrainian telecommunications company Kyivstar, said after crunching through 15 centimeters of fresh snow to reach a fenced-in mobile phone tower on the western fringe of Kyiv, the capital.

Dugrist and his coworkers offered a glimpse of their new daily routines, which involve using an app on their own phones to monitor which of the scores of phone towers in the capital area were receiving electricity, either during breaks from the controlled blackouts being used to conserve energy or from the generators that kick in to provide backup power.

One entry ominously read, in English, “Low Fuel.”

Stopping off at a service station before their rounds, the team members filled up eight 20-liter jerrycans with diesel fuel for a vast tank under a generator that relays power up a 50-meter cell tower in a suburban village that has had no electricity for days.

It’s one of many Ukrainian towns that have had intermittent power, or none at all, in the wake of multiple rounds of devastating Russian strikes in recent weeks targeting the country’s infrastructure – power plants in particular.

Kyivstar is the largest of Ukraine’s three main mobile phone companies, with some 26 million customers – or the equivalent of about two-thirds of the country’s population before Russia’s Feb. 24 invasion drove millions of people abroad, even if many have since returned.

The diesel generators were installed at the foot of the cell phone towers since long before the invasion, but they were rarely needed. Many Western countries have offered up similar generators and transformers to help Ukraine keep electricity running as well as possible after Russia’s blitz.

After emergency blackouts prompted by a round of Russian strikes on Nov. 23, Kyivstar deployed 15 teams of engineers simultaneously and called in “all our reserves” to troubleshoot the 2,500 mobile stations in their service area, Dugrist said.

He recalled rushing to the site of a destroyed cell tower when Russian forces pulled out of Irpin, a suburb northwest of Kyiv, earlier this year and getting there before Ukrainian minesweepers had arrived to give the all-clear signal.

The strain the war is putting on Ukraine’s mobile phone networks has reportedly driven up prices for satellite phone alternatives like Elon Musk’s Starlink system, which Ukraine’s military has used during the conflict, now in its 10th month.

After widespread infrastructure strikes last week, Ukrainian President Volodymyr Zelenskyy convened top officials to discuss the restoration work and supplies needed to safeguard the country’s energy and communication systems.

“Special attention is paid to the communication system,” he said, adding that no matter what the Russia has in mind, “we must maintain communication.”

Cities across China further unwound COVID restrictions Friday, loosening testing and quarantine rules in the wake of nationwide protests calling for an end to lockdowns and greater political freedoms.

Anger and frustration with China’s hardline pandemic response spilled out onto the streets last weekend in widespread demonstrations not seen in decades.

In the wake of the unrest across China, a number of cities have begun loosening COVID-19 restrictions, such as moving away from daily mass testing requirements, a tedious mainstay of life under Beijing’s stringent zero-COVID policy.

At the same time, authorities are continuing to seek to contain protests with heavy security on the streets, online censorship in full force, and surveillance of the population heightened.

As of Friday, the southwestern metropolis of Chengdu will no longer require a recent negative test result to enter public places or ride the metro, instead only requiring a green health code confirming they have not travelled to a “high risk” area.

In Beijing, health authorities called Thursday on hospitals not to deny treatment to people without a negative PCR test taken within 48 hours.

In January, a pregnant woman in the city of Xi’an miscarried after being refused hospital entry for not having a PCR test result.

China has seen a string of deaths after treatment was delayed by COVID restrictions, including the recent death of a 4-month-old baby who was stuck in quarantine with her father.

Those cases became a rallying cry during the protests, with a viral post listing the names of those who died because of alleged negligence linked to the pandemic response.

Many other cities with virus outbreaks are allowing restaurants, shopping malls and even schools to reopen, in a clear departure from previous tough lockdown rules.

In northwestern Urumqi, where a fire that killed 10 people was the spark for the anti-lockdown protests, authorities announced Friday that supermarkets, hotels, restaurants, and ski resorts would gradually be opened.

The city of over 4 million residents endured one of China’s longest lockdowns, with some areas shut in early August.

Home quarantine

An analysis by state-run newspaper People’s Daily on Friday quoted a number of health experts supporting local government moves to allow positive cases to quarantine at home.

The shift would be a marked departure from current rules, which require that they be held in government facilities.

The southern factory hub of Dongguan on Thursday said that those who meet “specific conditions” should be allowed to quarantine at home. It did not specify what those conditions would be.

The southern tech hub Shenzhen rolled out a similar policy Wednesday.

Central government officials have also signaled that a broader relaxation of zero-COVID policy could be in the works.

Speaking at the National Health Commission Wednesday, Vice Premier Sun Chunlan said the omicron variant was weakening and vaccination rates were improving, according to the state-run Xinhua news agency.

A central figure behind Beijing’s pandemic response, Sun said this “new situation” required “new tasks.”

She made no mention of zero-COVID in those remarks or in another meeting Thursday, suggesting the approach, which has disrupted the economy and daily life, might soon be relaxed.

Former NBA star Jeremy Lin, who plays for a Chinese team, was fined 10,000 yuan ($1,400) for “inappropriate remarks” on social media about quarantine facilities ahead of a game, China’s professional league announced Friday, as the government tries to stop protests against anti-virus controls that are among the world’s most stringent.

Also Friday, more cities eased restrictions, allowing shopping malls, supermarkets and other businesses to reopen following protests last weekend in Shanghai and other areas in which some crowds called for President Xi Jinping to resign. Urumqi in the northwest, site of a deadly fire that triggered the protests, announced supermarkets and other businesses were reopening.

Lin, who plays for the Loong Lions Basketball Club, made “inappropriate remarks about quarantine hotel-related facilities” where the team stayed Wednesday ahead of a game, the China Basketball Association announced. It said that “caused adverse effects on the league and the competition area.”

The ruling Communist Party is trying to crush criticism of the human cost and disruption of its “zero-COVID” strategy, which has confined millions of people to their homes. Protesters have been detained and photos and videos of events deleted from Chinese social media. Police fanned out across Shanghai, Beijing and other cities to try to prevent additional protests.

The CBA gave no details of Lin’s comments and there was no sign of them on his account on the popular Sina Weibo platform.

The Shanghai news outlet The Paper reported Lin posted a video complaining about hotel workout facilities in the city of Zhuji, south of Shanghai in Zhejiang province, ahead of games next week.

“Can you believe this is a weight room?” Lin was quoted as saying. “What kind of garbage is this?” The Paper said the video was deleted after “the situation was clarified” that the hotel was only for a brief stay required by regulations.

A representative of Vision China Entertainment, which says on its website it represents Lin, didn’t immediately respond to a request for comment. Phone calls to Loong Lions Basketball Club headquarters in the southern city of Guangzhou weren’t answered.

Lin, born in California to parents from Taiwan, was the first NBA player of Chinese or Taiwanese descent.

He played for California’s Golden State Warriors in 2010 before joining the New York Knicks in the 2011-12 season. He became the first Asian American to win an NBA championship with the Toronto Raptors in 2019. He played for the Beijing Ducks in 2019 before joining the Loong Lions.

On Friday, there were no signs of more protests.

The government reported 34,980 infections found in the past 24 hours, including 30,702 with no symptoms.

China’s case numbers are low, but “zero-COVID” aims to isolate every infected person. That has led local officials to suspend access to neighborhoods and close schools, shops and offices. Manufacturers including the biggest iPhone factory in central China use “closed-loop” management, which requires employees to live at their workplace without outside contact.

Demonstrations erupted Nov. 25 after a fire in an Urumqi apartment building killed at least 10 people.

That set off angry questions online about whether firefighters or victims trying to escape were blocked by locked doors or other anti-virus controls. Authorities denied that, but the deaths became a focus of public frustration.

Xi’s government has promised to reduce the cost and disruption of controls but says it will stick with “zero-COVID.” Health experts and economists expect it so stay in place at least until mid-2023 and possibly into 2024 while millions of older people are vaccinated in preparation for lifting controls that keep most visitors out of China.

Urumqi will “further increase efforts to resume production and commerce” by reopening hotels, restaurants, large supermarkets and ski resorts, the official newspaper Guangming Daily reported on its website, citing Sui Rong, a member of the Municipal Committee.

Elsewhere, the northern city of Hohhot in the Inner Mongolia region restarted bus service and allowed restaurants and small businesses to reopen, according to state media. Jinzhou in the northeast lifted curbs on movement and allowed businesses to reopen.

On Thursday, the metropolis of Guangzhou in the south, the biggest hotspot in the latest infection spike, allowed supermarkets and restaurants to reopen.

Other major cities including Shijiazhuang in the north and Chengdu in the southwest restarted bus and subway service and allowed businesses to reopen.

The Environmental Protection Agency on Thursday proposed increasing the amount of ethanol and other biofuels that must be blended into the nation’s fuel supplies over the next three years, a move welcomed by renewable fuel and farm groups but condemned by environmentalists and oil industry groups.

“This proposal supports low-carbon renewable fuels and seeks public input on ways to strengthen the program,” EPA Administrator Michael S. Regan said in a statement. “With this proposal, EPA seeks to provide consumers with more options while diversifying our nation’s energy mix.”

The proposal also includes new incentives to encourage the use of biogas from farms and landfills, and renewable biomass such as wood to generate electricity to charge electric vehicles. It’s the first time the EPA has set biofuel targets on its own instead of using numbers from Congress. The agency opened a public comment period and will hold a hearing in January.

Goal includes reducing fuel prices

The goal of the existing Renewable Fuel Standard is to reduce carbon emissions that contribute to climate change, expand the country’s fuel supply, strengthen energy security and reduce fuel prices for consumers. Ethanol is a key part of the economy in many Midwestern states, consuming about 40% of the nation’s corn supply.

But environmentalists argue it’s a net ecological and climate detriment because growing all that corn fosters unsustainable farming practices, while the oil industry says ethanol mandates constrain free market forces and limit consumer choice, and that higher blends can damage older vehicles.

Geoff Cooper, president and CEO of the Renewable Fuels Association, told reporters on a conference call that the EPA’s plan creates a “clear pathway for sustainable growth for our industry when it comes to the production and use of low-carbon fuels like ethanol.” He said it also bolsters the industry’s push for year-round sales of gasoline with a 15% ethanol blend, as well as sales of the 85% ethanol blend E85.

“As the administration is working to address climate change, we’ve long known that biofuels will play an important role in reducing greenhouse gases while having the added benefit of providing expanded opportunities for farmers,” National Farmers Union President Rob Larew said in a statement.

Climate campaigner calls plan ‘toxic’

Environmental groups said the plan offers false solutions to climate change.

“This is a toxic plan directly at odds with the Biden Administration’s commitment to Environmental Justice,” Sarah Lutz, climate campaigner at Friends of the Earth, said in a statement. “Charging electric vehicles with forests and factory farms should be a non-starter.”

Geoff Moody, senior vice president of the American Fuel & Petrochemical Manufacturers, said the Renewable Fuel Standard was meant to be a liquid fuels program, not an electric vehicle program. He urged the EPA to go back as it develops the final rule and reject “yet another massive regulatory subsidy for electric vehicle manufacturers.”

The EPA proposes to set the total target for all kinds of renewable fuels at 20.82 billion gallons for 2023, including 15 billion gallons from corn ethanol.

The target would grow to 22.68 billion gallons for 2025, including 15.25 billion gallons of corn ethanol. The plan also calls for growth in cellulosic biofuels — which are made from fibrous plant materials — biomass-based diesel and other advanced biofuels.

Republican Senator Chuck Grassley of Iowa, which is the top corn and ethanol producing state in the United States, said in a statement that the EPA should have gone further to require even more use of advanced biofuels to move freight, which he said would help lower prices for consumer goods.

Cooper said there’s probably no way to meet the proposed higher targets without more use of E15 and E85 instead of the conventional 10% ethanol mix. That makes it important to eliminate regulations that block summertime sales of E15, he said.

So, he predicted, the EPA’s proposal should bolster prospects for legislation introduced this week by Democratic U.S. Senator Amy Klobuchar of Minnesota and GOP Senator Deb Fischer of Nebraska to allow year-round sales of E15 nationwide. E15 sales are usually prohibited between June 1 and September 15 because of concerns that it adds to smog in high temperatures.

Eight Midwestern governors asked the EPA in April to allow year-round sales of E15 in their states. But Cooper said the new bill would provide a “nationwide fix” that even the American Petroleum Institute considers preferable to the current patchwork of temporary waivers and ad hoc solutions.

Tech billionaire Elon Musk said his Neuralink company is seeking permission to test its brain implant in people soon.

In a “show and tell” presentation livestreamed Wednesday night, Musk said his team is in the process of asking U.S. regulators to allow them to test the device. He said he thinks the company should be able to put the implant in a human brain as part of a clinical trial in about six months, though that timeline is far from certain.

Musk’s Neuralink is one of many groups working on linking brains to computers, efforts aimed at helping treat brain disorders, overcoming brain injuries and other applications.

The field dates to the 1960s, said Rajesh Rao, co-director of the Center for Neurotechnology at the University of Washington. “But it really took off in the ’90s. And more recently we’ve seen lots of advances, especially in the area of communication brain computer interfaces.”

Rao, who watched Musk’s presentation online, said he doesn’t think Neuralink is ahead of the pack in terms of brain-computer interface achievements. “But … they are quite ahead in terms of the actual hardware in the devices,” he said.

The Neuralink device is about the size of a large coin and is designed to be implanted in the skull, with ultra-thin wires going directly into the brain. Musk said the first two applications in people would be restoring vision and helping people with little or no ability to operate their muscles rapidly use digital devices.

He said he also envisions that in someone with a broken neck, signals from the brain could be bridged to Neuralink devices in the spinal cord.

“We’re confident there are no physical limitations to enabling full body functionality,” said Musk, who recently took over Twitter and is the CEO of Tesla and SpaceX.

In experiments by other teams, implanted sensors have let paralyzed people use brain signals to operate computers and move robotic arms. In a 2018 study in the journal PLOS ONE, three participants with paralysis below the neck affecting all of their limbs used an experimental brain-computer interface being tested by the consortium BrainGate. The interface records neural activity from a small sensor in the brain to navigate things like email and apps.

A recent study in the journal Nature, by scientists at the Swiss research center NeuroRestore, identified a type of neuron activated by electrical stimulation of the spinal cord, allowing nine patients with chronic spinal cord injury to walk again.

Researchers have also been working on brain and machine interfaces for restoring vision. Rao said some companies have developed retinal implants, but Musk’s announcement suggested his team would use signals directly targeting the brain’s visual cortex, an approach that some academic groups are also pursuing, “with limited success.”

Neuralink did not immediately respond to an email to the press office. Dr. Jaimie Henderson, a neurosurgery professor at Stanford University who is an adviser for Neuralink, said one way Neuralink is different from some other devices is that it has the ability to reach into deeper layers of the brain. But he added: “There are lots of different systems that have lots of different advantages.”

Cameroonian health workers and people with HIV marched for World AIDS Day on December 1, calling for access to treatment for patients in conflict areas.

About half a million Cameroonians have HIV, and at least 1,000 live in troubled western regions and the border with Nigeria. The protesters urged Cameroon’s military, separatists, and militants to allow all HIV patients access to needed treatment.

Marie Chantal Awoulbe, who belongs to the Cameroon Network of Adolescents and Positive Youths, which encourages those with AIDS to get regular treatment, took part in the protest and World AIDS Day activities at Chantal Biya International Research Centre in Yaounde. The center carries out research on AIDS, and supports programs to treat and support vulnerable people with HIV.

Awoulbe said her network is asking both armed groups and government troops to stop deaths among people with AIDS where there are armed conflicts by allowing the patients access to regular treatment.

Cameroon’s public health ministry says similar protests and activities to encourage free screening took place in 70 hospitals, with at least 30 hospital workers and people with AIDS taking part at each of the hospitals.

The Cameroon government accuses separatists in the country’s west of attacking hospitals and abducting health care workers. Activists also accuse government troops of attacking and arresting hospital staff suspected of treating civilians the military believes are either fighters or sympathize with separatists.

In April, medical aid group Doctors Without Borders suspended work in Cameroon’s troubled Southwest region to protest the rearrest of four of its staff members. Authorities accused the staffers of cooperating with regional separatists, but the organization denied it.

Medical staff members say intimidation and abduction of health workers, and ceaseless battles between government troops and separatist fighters make it impossible for medical supplies to reach the troubled English-speaking regions.

Twenty-eight-year-old Betrand Lemfon said he and several dozen people with AIDS moved from Jakiri, an English-speaking northwestern town, to Bafoussam, a French-speaking commercial city. He said he and others with the disease were afraid of dying in Jakiri because they did not have access to regular treatment.

“There are a lot of persons out there who are in need of medications, so if we could have the opportunity and chance for medications to always reach every interior part of the North-West region, South-West region who are hit by the crisis, it will help the adolescents, young persons and children living with HIV to take their ARVs [antiretroviral medicines] and stay healthy,” he said.

Lemfon spoke via the messaging app WhatsApp from Bafoussam.

Cameroon’s military says it will protect all health workers and civilians in the troubled regions.

The government says the number of people with the disease in Cameroon has decreased from about 970,000 in 2010 to 500,000 in 2021.

Health officials say the decline is due to increasing awareness of the disease and its consequences. The government says sexual behavior is changing, with the number of people using condoms or abstaining from sex increasing.

Honorine Tatah, a government official in charge of AIDS control in Cameroon, said unlike in 2020 when there was resistance due to lack of awareness, many more civilians now accept systematic screening for HIV.

“During antenatal care, a woman is screened for a number of diseases including hepatitis B, HIV and if you are tested positive, you are eligible for treatment and that treatment will reduce the chances of a child getting infected with HIV. The treatment is free of charge,” Tatah said.

World AIDS Day was the first international day for global health, starting in 1988. It allows people all over the world to join in the battle against HIV, to support those with HIV, and to remember those who have died from an AIDS-related illness.

In October, Zimbabwe became to first African country to approve the use of the injectable HIV prevention drug known as cabotegravir. As Columbus Mavhunga reports from Harare, Zimbabwe, many are eager for the drug to become available. Videography by Blessing Chigwenhembe.
…

A new, long-lasting drug could be a game-changer for preventing HIV infections, experts say.

Advocates are hopeful that those who need it most in low- and middle-income countries will not have to wait for it as long as they have for previous HIV drugs. But questions remain about access and price.

The drug is called cabotegravir and is delivered as a shot once every other month. In clinical trials, it did a better job at preventing infection than another option — a pill taken once a day.

The bimonthly injection seems to be an easier treatment regimen to stick to than daily pills, according to Mitchell Warren, executive director of AVAC, an HIV prevention advocacy organization.

“If you can take a pill every day, that’s great. But if you can’t, we see a lot of people who start [taking the pills] who don’t continue,” he said.

Aside from the inconvenience, there can be a stigma attached to taking the pills, Warren said. The drugs for prevention, called pre-exposure prophylaxis, or PrEP, are the same as the drugs used to treat HIV infection.

“If you’re a young person and your parents find your pill bottle, they say, ‘Why are you taking this pill? Are you HIV infected?’ And the young person may say, ‘No, I’m protecting myself,'” Warren said. “And they say, ‘Well, why are you having sex?'”

Long-lasting drugs like cabotegravir or another new product, a once-a-month vaginal ring, offer patients more choices, he added.

About 1.5 million people were newly infected with HIV in 2021, according to the World Health Organization, about 60% of them in Africa.

Uganda and Zimbabwe approved cabotegravir for PrEP earlier this year. They are the first countries in sub-Saharan Africa to do so.

These approvals come less than a year after the U.S. Food and Drug Administration authorized it.

That’s progress, Warren said. FDA approved PrEP pills in 2012, but “it took three years before any African regulatory agency approved it. So, we’ve already seen a condensing of that timeline.”

Cabotegravir costs $22,000 per year in the United States. ViiV Healthcare, the company that makes the drug, has not officially announced what it will cost in low- and middle-income countries, but it is expected to be much lower. Some aid groups have indicated that ViiV will offer the drug at $250 per year.

“The problem is that actually that won’t be really affordable for countries who need to roll it out and scale up,” said Jessica Burry, a pharmacist with humanitarian group Doctors without Borders.

PrEP pills cost about $54 per year, Warren said.

“The hope is that early in 2023, we can see a price point that is much closer to that 54 [dollars] than to the 250 [dollars],” he said. “Hopefully, in the $100 range per year.”

ViiV said it is working with the U.N.-backed Medicines Patent Pool to allow generic manufacturers to produce cabotegravir at a lower price for low- and middle-income countries.

ViiV said cabotegravir is more complicated to manufacture than most HIV drugs. No generic manufacturers have been selected yet. Once they are, it will take about three to five years before a generic version is on the market.

The company has filed for regulatory approval in 11 countries so far. Burry says there should be more.

“If they’re going to be the only supplier for the next four or five years until generics are available, then they really need to step up to the plate and actually file, register and get that drug available,” she said.

Demand for the drug is unclear. PrEP pills have been slow to catch on.

About 845,000 people in more than 50 countries took them in 2020, but the United Nations was aiming for 3 million by that time.

“We don’t have a ton of PrEP users, so if you’re ViiV, you’re looking at a very small market,” Warren said.

Warren said providers and advocates need to help grow that market. They need to do a better job connecting people at risk with programs that offer PrEP, he added.

“Some of the early PrEP programs began with us thinking that if you just bought the product, people would magically show up,” he said.

Warren hopes to change that as part of a coalition that includes ViiV, the Bill and Melinda Gates Foundation, the World Health Organization and others.

“There’s a huge effort in this coalition to bring in civil society from day one, and the communities that this product is meant to help and support,” he said.

The slow uptake means PrEP has not yet shown that it can make much of a real-world impact, Warren noted. He hopes to see research programs launch next year to find the best ways to reach the communities most at risk and lower infection rates.

“If we can’t show that in the next three years, then we don’t necessarily need all these generic manufacturers, because there will not be a market for this product,” he said.

Deforestation in the Brazilian Amazon slowed slightly last year, a year after setting a 15-year high, according to closely watched numbers published Wednesday. The data was released by the National Institute for Space Research.

The agency’s Prodes monitoring system shows the rainforest lost an area roughly the size of Qatar, about 11,600 square kilometers in the 12 months from August 2021 to July 2022.

That is down 11% compared with the previous year, when more than 13,000 square kilometers were destroyed.

For more than a decade deforestation in the Brazilian Amazon declined dramatically and never rose back above 10,000 square kilometers. Then came the presidency of far-right President Jair Bolsonaro, beginning in January 2019.

This will be the last report published under Bolsonaro, who lost his reelection bid and will leave office January 1. But part of the destruction that took place on his watch will not appear until next year, including the key months from August to October 2022. A because it is the dry season.

An analysis of the new yearly data from Climate Observatory, a network of environmental groups, shows that in the four years of Bolsonaro’s leadership, deforestation rose 60% over the previous four years. That is the largest percentage rise under a presidency since satellite monitoring began in 1998.

In one state, Para, a fierce rate of destruction fell by 21% yet it was still the center of one-third of all Brazil’s Amazon forest loss. Part of the tree cutting and burning happens in areas that are ostensibly protected. One such area is Paru State Forest, where the nonprofit Amazon Institute of People and the Environment registered 2 square kilometers of deforestation in just October.

“In recent years, deforestation has reached protected areas where previously there was almost no destruction,” Jacqueline Pereira, a researcher with the Amazon Institute, told The Associated Press. “In Paru’s region, the destruction is driven by lease of land for soybean crops and cattle.”

Another critical area is the southern part of the state of Amazonas, the only state that increased deforestation in the most recent data, by 13% compared to the year before. It’s largely attributable to Bolsonaro’s push to pave about 400 kilometers of the only road that connects Manaus, home to 2.2 million people, with Brazil’s larger urban centers further south. Most Amazon deforestation occurs alongside roads where access is easier and land value is higher.

Researchers and environmentalists have blamed Bolsonaro’s policies for the surge in deforestation. The administration weakened environmental agencies and backed legislative measures to loosen land protections in the name of economic development, paired with a view of occupying a sparsely populated territory at any cost. This policy has emboldened land robbers and spurred more illegal mining.

Bolsonaro’s successor, leftist former President Luiz Inácio Lula da Silva, promised cheering crowds at the recent U.N. climate conference in Egypt to end all deforestation in the country by 2030.

“There will be no climate security if the Amazon isn’t protected,” he said.

The last time da Silva was president, from 2003 to 2010, deforestation fell sharply. On the other hand, he backed initiatives that set in motion destruction in the long run, such as the construction of the mammoth Belo Monte hydroelectric dam and generous loans to the beef industry. Chopping down forest for pasture is the primary driver of deforestation.

The Amazon rainforest, which covers an area twice the size of India, acts as a buffer against climate change by absorbing large amounts of carbon dioxide. It’s also the most biodiverse forest in the world, and the home of tribes that have lived in the forest for thousands of years, some of them living in isolation.

“If da Silva wants to decrease forest destruction by 2023, he must have zero tolerance for environmental crime from Day One of his administration. That includes holding accountable those who sabotaged environmental governance in the country while in office over the past four years,” said Marcio Astrini, executive secretary of the Climate Observatory.

Malawi and the World Health Organization are rolling out a new malaria vaccine for young children that backers say will reduce deaths from the mosquito-borne disease.

The RTSS vaccine was pilot tested on more than one million children in Ghana, Kenya and Malawi and recommended a year ago by the WHO. Despite a low effectiveness rate of 30%, the vaccine has raised hopes that some of the more than 400,000 people who die annually from malaria can be saved. 

Malaria remains a huge public health problem in Malawi, with about one third of its 20 million people getting infected each year. 

According to the ministry of health, the disease kills five Malawians every day, most of them children under the age of five or pregnant women who were not presented early enough for care.  

The health ministry says the first phase of the vaccination campaign will target 330,000 children, who were not reached during vaccine trials. 

The vaccine, sold by GlaxoSmithKline as Mosquirix, is meant for children under the age of five and requires four doses. 

“Malaria is major problem in children. They are the ones at highest risk of dying,” said Dr. Charles Mwansambo, Malawi’s secretary for health. “That’s why even when we were doing the earlier studies, we found that once we get maximum benefit, we should target this age group. The main reason is that they are the ones that are most likely to die from malaria.” 

Last year, the government launched a nationwide anti-malaria initiative known as Zero Malaria Starts with Me, aimed at eliminating the disease by 2030. 

Mwansambo said the vaccine is a key part of that initiative. 

“It actually prevents about 33 percent of deaths. Meaning that if you add the 33 to those that we can prevent using insecticide treated nets, if will also add on those [we can] prevent by indoor residual spraying, it [can] add up to something significant that will end up eliminating malaria,” he said. 

However, the Bill and Melinda Gates Foundation, backers of the vaccine, have raised concerns about whether the vaccine is worth the cost. 

In July, the Associated Press quoted Philip Welkhoff, director of malaria programs for the Gates Foundation, as saying the foundation will no longer offer direct financial support for the vaccine, although it will fund an alliance backing the vaccine. 

He said Mosquirix has much lower efficacy than the foundation would like and that the vaccine is relatively expensive and logistically challenging to deliver. 

Dr. Neema Kimambo, a WHO representative in Malawi, said the malaria vaccine itself is not a silver bullet but part of a combination of all interventions to fight the disease. 

“Where it [vaccination] was done, we have seen how it has reduced under-five deaths and we believe that as we expand now, we are definitely to save more lives of children under five,” she said. 

Maziko Matemba, a health activist and community health ambassador in Malawi, said he hopes the malaria vaccine efficacy will improve as time goes by. 

“I have an example with COVID-19. When we had AstraZeneca, the efficacy when it started — as you know it was also a new vaccine — it was less that certain percentage and people said no it was less than this. But over time, we found that the efficacy has gone up,” Matemba said. “So we are monitoring the launch of this new vaccine with keen interest.

“I know that other partners are saying the worthiness of investment is not worth it, but looking at the way we are coming from, Malawi in particular, this could be one of the tools to prevent malaria.” 

Besides WHO, other partners supporting Malawi in the fight against malaria include USAID, UNICEF, the Global Fund to Fight AIDS, Tuberculosis and Malaria and a global health nonprofit organization, PATH.
