A study by the World Bank on Thursday said urgent action is needed to address rising sea levels in the Pacific atoll islands of Kiribati, the Marshall Islands and Tuvalu, which under current projections could be 50% to 80% submerged in the next 50 years.

The World Bank’s “Pacific Atoll Countries Country Climate and Development Report” says the low-lying nations and the roughly 200,000 people who live on them face some of the most severe existential threats from climate change of any region in the world.

The study cites projected sea level rises of up to a half meter in the last half of this century and suggests 50% to 80% of major urban areas in the countries could be underwater.

The region is already seeing annual losses from climate events — such as more frequent and powerful storms — equivalent to 7% of the total economic output in Tuvalu. About 3% to 4% of output in the Marshall Islands and Kiribati are projected to increase.

The bank said that without urgent global and local action, a 1-in-20-year climate event in Tuvalu could lead to damage and losses equivalent to 50% of current annual output by 2050.

The study makes near-, medium- and long-term recommendations for the island nations. The near- and medium-term suggestions include investments in sustainable construction to protect freshwater resources, fisheries and energy supplies, among other crucial infrastructure.

The study’s long-term suggestions include investments in education, legal and regulatory frameworks, economic development and climate resilience.

The study also called on the international donor community to make contributions to the Pacific atoll countries, which still face a significant climate funding gap.

The World Bank produces diagnostic country climate and development reports, CCDRs, that integrate climate change and development considerations and suggest concrete actions that countries can take to mitigate and adapt to climate change. The bank has completed over 45 CCDRs around the world as of October 2024.

Islamabad — The World Health Organization has labeled a forced repatriation of Afghan nationals from Pakistan as a “major setback” for polio eradication efforts, contributing to the regional resurgence of the paralytic disease.

Pakistan and neighboring Afghanistan are the only two polio-endemic nations, reporting 49 and 23 cases respectively, so far this year, up from only six cases each in 2023. 

The latest case in Pakistan was confirmed Thursday in the southwestern province of Balochistan, which sits on the Afghan border and accounts for half the cases reported in 2024.

“Until you get rid of polio completely, it will resurge and come back, and this is what we are seeing now in Pakistan [where] nearly half of the districts are infected, and in Afghanistan, a third of the provinces are infected,” Hamid Jafari, the WHO director for the Eastern Mediterranean, said Wednesday while discussing causes of polio resurgence in both countries. 

“I think the major setback was a forced repatriation of Afghan nationals that led to a massive and unpredictable movement of populations within Pakistan and across both borders and within Afghanistan, so the virus moved with these populations,” Jafari told the virtual discussion hosted by the Global Polio Eradication Initiative, or GPEI. 

The United Nations High Commissioner for Refugees has said that Pakistan’s crackdown on undocumented foreign nationals has resulted in more than 730,000 Afghan migrants returning to Afghanistan since August 2023.

Jafari also mentioned other factors contributing to the rise of polio in Pakistan, including authorities’ inability to consistently carry out vaccination campaigns in areas affected by militancy, where children cannot be effectively immunized against the crippling disease. He also highlighted the presence of “significant vaccine hesitancy and community boycotts” rooted in public frustration over the lack of essential services in impoverished districts.

Pakistani and WHO officials say vaccine boycotts in some regions also result from the false propaganda that anti-polio campaigns are a Western plot to sterilize Muslim children. Additionally, anti-government militants in violence-hit regions occasionally stage deadly attacks on polio teams, suspecting them of spying for authorities, routinely disrupting vaccination drives in districts near the Afghan border. 

Afghan polio ban

While sharing the latest polio situation in Afghanistan, the senior WHO official stated they are collaborating with various humanitarian actors and partners to promote vaccination against polio and all other diseases.

“We cannot implement house-to-house vaccination,” Jafari stated, referencing the ban imposed by Taliban authorities on polio teams over security concerns. 

“The program is working closely with [Taliban] authorities to re-update micro plans and work closely with the communities and local officials to make sure children are mobilized to vaccination sites,” he added. 

In September, the Taliban abruptly halted house-to-house vaccine deliveries in parts of southern Afghanistan, including Kandahar, without publicly stating any reason. 

An independent monitoring board of the GPEI recently said that the Taliban’s action had stemmed from their “administration’s concerns about covert surveillance activities.” The report quoted de facto Afghan authorities as explaining that their leadership is living in Kandahar and has concerns about their security.

Jafari stated that Pakistan and Afghanistan are taking measures to address the challenges in their bid “to rebuild community confidence” and work closely with security agencies in both countries to be able to access all children. 

He cautioned that the current resurgence of polio in Pakistan and Afghanistan does not guarantee a low point next year.

“We are confident that we will come very close to elimination, but the key is to make sure that in these final safe havens for poliovirus in insecure areas, among migrant and mobile populations, and vaccine-hesitant communities, we can finally overcome these residual challenges to make sure that finally polio is eradicated,” the regional WHO director said. 

Polio once paralyzed an estimated 20,000 children in Pakistan each year until the country initiated national vaccination campaigns in the 1990s to control the infections, according to the WHO. In 2019, there were 176 reported cases in Pakistan and Afghanistan. In 2021 and 2022, however, the countries reported only one and two infections, respectively.

BAKU, Azerbaijan — For the third straight year, efforts to fight climate change haven’t lowered projections for how hot the world is likely to get — and recent developments in China and the United States are likely to slightly worsen the outlook, according to an analysis Thursday.

The analysis comes as countries come together for the 29th edition of the United Nations climate talks, hosted in Baku, Azerbaijan, where nations are trying to set new targets to cut emissions of heat-trapping gases and figure out how much rich nations will pay to help the world with that task.

But Earth remains on a path to be 2.7 degrees Celsius warmer than pre-industrial times, according to Climate Action Tracker, a group of scientists and analysts who study government policies and translate that into projections of warming.

If emissions are still rising and temperature projections are no longer dropping, people should wonder if the United Nations climate negotiations known as COP are doing any good, said Climate Analytics CEO Bill Hare.

“There’s an awful lot going on that’s positive here, but on the big picture of actually getting stuff done to reduce emissions … to me it feels broken,” Hare said.

Climate action is stifled by the biggest emitters

The world has already warmed 1.3 degrees Celsius above pre-industrial times. That’s near the 1.5-degree limit that countries agreed to at 2015 climate talks in Paris. Climate scientists say the atmospheric warming, mainly from human burning of fossil fuels, is causing ever more extreme and damaging weather including droughts, flooding and dangerous heat.

Climate Action Tracker does projections under several different scenarios, and in some cases, those are going up slightly.

One projected track based on what countries promise to do by 2030 is up to 2.6 degrees Celsius, a tenth of a degree warmer than before. And even the analysts’ most optimistic scenario, which assumes that countries all deliver on their promises and targets, is at 1.9 Celsius, also up a tenth of a degree from last year, said study lead author Sofia Gonzales-Zuniga of Climate Analytics, one of the main groups behind the tracker.

“This is driven highly by China,” Gonzales-Zuniga said. Even though China’s fast-rising emissions are starting to plateau, they are peaking higher than anticipated, she said.

Another upcoming factor not yet in the calculations is the U.S. elections. A Trump administration that rolls back the climate policies in the Inflation Reduction Act, and carries out the conservative blueprint Project 2025, would add 0.04 degree Celsius to warming projections, Gonzales-Zuniga said. That’s not much, but it could be more if other nations use it as an excuse to do less, she said. And a reduction in American financial aid could also reverberate even more in future temperature outlooks.

“For the U.S. it is going backwards,” said Hare. At least China has more of an optimistic future with a potential giant plunge in future emissions, he said.

“We should already be seeing (global) emissions going down” and they are not, Hare said. “In the face of all of the climate disasters we’ve observed, whether it’s the massive floods in Nepal that killed hundreds of people or whether it’s the floods in Valencia, Spain, that just killed hundreds of people. The political system, politicians are not reacting. And I think that’s something that people everywhere should be worried about.”

Experts say $1 trillion is needed in climate cash for developing nation

The major battle in Baku is over how much rich nations will help poor countries to decarbonize their energy systems, cope with future harms of climate change and pay for damage from warming’s extreme weather. The old goal of $100 billion a year in aid is expiring and Baku’s main focus is coming up with a new, bigger figure.

A special independent group of experts commissioned by United Nations Secretary-General Antonio Guterres issued its own estimate of costs and finances on Thursday, calling for a tripling of the old commitment.

“Advanced economies need to demonstrate a credible commitment” to helping poor nations, the report said.

A coalition of poor nations at the Baku talks are asking for $1.3 trillion in annual climate finance. The independent experts’ report said about $1 trillion a year is needed by developing nations from all outside sources, not just government grants.

The report detailed how expensive decarbonizing the world’s economy would be, how much it would cost and where the money could come from. Overall climate adaption spending for all countries is projected to reach $2.4 trillion a year.

“The transition to clean, low-carbon energy, building resilience to the impacts of climate change, coping with loss and damage, protecting nature and biodiversity, and ensuring a just transition, require a rapid step-up in investment in all countries,” said the report.

Washington — National Geographic scientists say they’ve discovered the world’s largest coral near the remote Solomon Islands in the Pacific Ocean — an undersea mass that is so big, it can be seen from space.

The man who found it, Manu San Felix, director of cinematography for National Geographic Society’s Pristine Seas, a program dedicated to marine conservation, says the giant organism measures 34 meters wide and 32 meters long and is “close to the size of a cathedral.”

“I see this as a living library that has the information of the conditions of the oceans for centuries,” he told reporters this week, underscoring it is a reminder of the need to better protect the ocean from global climate change.

Eric Brown, a Pristine Seas coral scientist, said the enormous coral species, Pavona clavus, is healthy and has “high reproductive potential,” making it essential to help other coral reef ecosystems recover from the damage of a warming ocean.

Corals “are very vulnerable ecosystems. So, it’s important for us to do whatever we can to protect these environments that are both small and mighty,” Brown said at a Tuesday press briefing to announce the find.

The announcement comes as world leaders gather for the United Nations climate conference, known as COP29, in Azerbaijan. Attendees are trying to agree on new mechanisms to finance a global energy transition to renewables and help nations like the Pacific Islands pay for the cost of adapting to rising oceans.

Pristine Seas is also encouraging nations to designate marine protected areas, or MPAs. The goal is to protect 30% of the world’s oceans by 2030.

Palau President Surangel Whipps Jr. is attending the summit. Palau has walled off 80% of its waters to development, while the nearby Pacific Island nation of Niue has designated 40% of its waters for protection.

“It cannot just be big countries. Small countries need to do their part,” he told VOA in an interview. “So, it’s all of us working together … protecting our oceans, because we know that healthy oceans are an important part of the ecosystem and important in regulating climate.”

Solomon Islands Prime Minister Jeremiah Manele agreed.

“Our survival depends on healthy coral reefs, so this exciting discovery underlines the importance of protecting and sustaining them for future generations,” he said in a press release.

But so far, the Solomon Islands has created a network of 79 designated ocean conservation areas — less than 1% of its exclusive economic zone. What’s more, its economy is largely dependent on forestry — the very industry that threatens the viability of coral through sedimentation.

“All that sediment is going onto a reef, and it’s smothering the reef, thereby preventing the corals from being able to feed, to grow, to reproduce,” Molly Timmers, Pristine Seas lead scientist on the Solomon Islands, said at the press briefing.

According to the Observatory of Economic Complexity, an online platform that seeks to visualize the distribution of international trade, the Solomons exported $308 million in rough wood in 2022, with $260 million of it going to China.

VOA asked Chief Dennis Marita, director of culture at the Ministry of Culture & Tourism, how the government can find a balance.

“Much of the logging activities are happening on the mainland” away from the coral, Marita said in an interview, but “there needs to be a serious awareness about the impacts of what’s happening in the logging industry to the marine environment.”

Marita sees this coral discovery as a way to attract researchers, biologists and tourists to bring in revenue to the small island nation of 740,000 people. Earlier this week, the Solomon Islands signed an agreement with China to provide visa-free travel between the two countries.

“Suddenly, people will start coming to the island, but then we need to be prepared for them, and also, we need to ensure that the coral is safeguarded,” Marita said.

Dr. Daniel Barshis of Old Dominion University’s Ecological Sciences Department in Norfolk, Virginia, said that idea has merit.

“I would imagine this discovery would draw tourists to the area, similar to how old-growth trees inspire folks to visit,” he told VOA via email.

“The fact that [corals] like this still exist is a reminder that coral reefs are still surviving and deserve us working as hard as we possibly can to save them from some of the worst-case scenarios if we don’t reverse course on greenhouse gas emissions as soon as possible,” said Barshis.

NEW YORK — The decline in U.S. drug overdose deaths appears to have continued this year, giving experts hope the nation is seeing sustained improvement in the persistent epidemic. 

There were about 97,000 overdose deaths in the 12-month period that ended June 30, according to provisional Centers for Disease Control and Prevention data released Wednesday. That’s down 14% from the estimated 113,000 for the previous 12-month period. 

“This is a pretty stunning and rapid reversal of drug overdose mortality numbers,” said Brandon Marshall, a Brown University researcher who studies overdose trends. 

Overdose death rates began steadily climbing in the 1990s because of opioid painkillers, followed by waves of deaths led by other opioids like heroin and — more recently — illicit fentanyl. Provisional data had indicated a slight decline for 2023, and the tally released Wednesday showed that the downward trend has kept going. 

Of course, there have been moments in the last several years when U.S. overdose deaths seemed to have plateaued or even started to go down, only to rise again, Marshall noted. 

“This seems to be substantial and sustained,” Marshall said. “I think there’s real reason for hope here.” 

Experts aren’t certain about the reasons for the decline, but they cite a combination of possible factors. 

One is COVID-19. In the worst days of the pandemic, addiction treatment was hard to get, and people were socially isolated — with no one around to help if they overdosed. 

“During the pandemic we saw such a meteoric rise in drug overdose deaths that it’s only natural we would see a decrease,” said Farida Ahmad of the CDC’s National Center for Health Statistics. 

Still, overdose deaths are well above what they were at the beginning of the COVID-19 pandemic. 

The recent numbers could represent the fruition of years of efforts to increase the availability of the overdose-reversing drug naloxone, and addiction treatments such as buprenorphine, said Erin Winstanley, a University of Pittsburgh professor who researches drug overdose trends. 

Marshall said such efforts likely are being aided by money from settlements of opioid-related lawsuits, brought by state, local and Native American governments against drugmakers, wholesalers and pharmacies. Settlement funds have been rolling out to small towns and big cities across the U.S., and some have started spending the money on naloxone and other measures. 

Some experts have wondered about changes in the drug supply. Xylazine, a sedative, has been increasingly detected in illegally manufactured fentanyl, and experts are sorting out exactly how it’s affecting overdoses. 

In the latest CDC data, overdose death reports are down in 45 states. Increases occurred in Alaska, Nevada, Oregon, Utah and Washington. 

The most dramatic decreases were seen in North Carolina and Ohio, but CDC officials voiced a note of caution. Some jurisdictions have had lags in getting death records to federal statisticians — particularly North Carolina, where death investigations have slowed because of understaffing at the state medical examiner’s office. The CDC made estimates to try to account for incomplete death records, but the decline in some places may ultimately turn out not to be as dramatic as initial numbers suggest. 

Another limitation of the provisional data is that it doesn’t detail what’s happening in different groups of people. Recent research noted the overdose deaths in Black and Native Americans have been growing disproportionately larger. 

“We really need more data from the CDC to learn whether these declines are being experienced in all racial ethnic subgroups,” Marshall said.

BAKU, Azerbaijan — When more than two dozen world leaders deliver remarks at the United Nations’ annual climate conference on Wednesday, many have detailed their nations’ firsthand experience with the catastrophic weather that has come with climate change.

“Over the past year, catastrophic floods in Spain, Bosnia and Herzegovina as well as well as in southern Croatia have shown the devastating impact of rising temperatures,” said Croatia’s prime minister, Andrej Plenkovic. “The Mediterranean, one of the most vulnerable regions, calls for urgent action.”

The Greek prime minister said Europe and the world needs to be “more honest” about the trade-offs needed to keep global temperatures down.

“We need to ask hard questions about a path that goes very fast, at the expense of our competitiveness, and a path that goes some much slower, but allows our industry to adapt and to thrive,” he said. His nation this summer was hammered by successive heat waves after three years of below-average rainfall. In Greece, the misery included water shortages, dried-up lakes and the death of wild horses.

Other speakers on the list include Pakistan Prime Minister Shehbaz Sharif, whose nation has seen deadly flooding this year from monsoon rains that scientists say have become heavier with climate change. Just two years ago, more than 1,700 people died in widespread flooding. Pakistan has also suffered from dangerous heat, with thousands of people hospitalized with heatstroke this spring as temperatures soared to 47 degrees Celsius.

Also on the list of speakers Wednesday is Bahamas Prime Minister Philip Edward Davis. Like many other countries in the Global South, the Bahamas has piled up debt from warming-connected weather disasters it did little to cause, including Hurricanes Dorian in 2019 and Matthew in 2016. Leaders have been seeking help and money from the Global North and oil companies.

Early on Wednesday, ministers and officials from African nations called for initiatives to advance green development on the continent and strengthen resilience to extreme weather events — from floods to droughts — across the region.

Plenty of big names and powerful countries are noticeably absent from COP29 this year. That includes the 13 largest carbon dioxide-polluting countries — a group responsible for more than than 70% of the heat-trapping gases emitted last year — were missing. The world’s biggest polluters and strongest economies — China and the United States — didn’t send their No. 1s. Neither did India and Indonesia.

But U.K. Prime Minister Keir Starmer was there, and he announced an 81% emissions reduction target on 1990 levels by 2035, in line with the Paris Agreement goal to limit warming to 1.5 degrees Celsius above pre-industrial times. That’s up from the 78% the U.K. had already pledged.

The main focus of this year’s talks is climate finance — wealthier nations compensating poor countries for damages from climate change’s weather extremes, helping them pay to transition their economies away from fossil fuels and helping them with adaptation.

TORONTO, canada — A teenager is in critical condition in a British Columbia children’s hospital, sick with Canada’s first presumptive human case of avian influenza.

“This was a healthy teenager prior to this, so no underlying conditions,” said provincial health officer Bonnie Henry in a news conference on Tuesday. “It just reminds us that in young people this is a virus that can progress and cause quite severe illness, and the deterioration that I mentioned was quite rapid.”

British Columbia health officials said on Saturday the province had detected Canada’s first human case of H5 bird flu in a teenager.

Henry said the province is still identifying the exact strain but assumes the case is H5N1.

The World Health Organization says H5N1’s risk to humans is low because there is no evidence of human transmission, but the virus has been found in an increasing number of animals, including cattle in the United States.

Henry would not disclose the teen’s gender or age but said the patient had first developed symptoms on November 2 and was tested on November 8, when admitted to a hospital. Symptoms included conjunctivitis, fever and coughing.

As of Tuesday, the teen was hospitalized with acute respiratory distress syndrome, she said.

The teen had no farm exposure but had been exposed to dogs, cats and reptiles, Henry said. No infection source had been identified. “That is absolutely an ongoing investigation.”

More severe illness takes place when the virus binds to receptors deep in the lungs, she said.

Public health officials had identified and tested about three dozen contacts and had not found anyone infected with the virus.

There has been no evidence that the disease is easily spread between people. But if that were to happen, a pandemic could unfold, scientists have said.

Earlier in November, the U.S. Centers for Disease Control and Prevention asked that farm workers exposed to animals with bird flu be tested for the virus even if they did not have symptoms.

Bird flu has infected nearly 450 dairy farms in 15 U.S. states since March, and the CDC has identified 46 human cases of bird flu since April.

In Canada, British Columbia has identified at least 26 affected premises across the province, Henry said Tuesday, and numerous wild birds have tested positive.

Canada has had no cases reported in dairy cattle and no evidence of bird flu in samples of milk.

BAKU, Azerbaijan — World leaders are converging Tuesday at the United Nations annual climate conference in Baku, Azerbaijan although the big names and powerful countries are noticeably absent, unlike past climate talks which had the star power of a soccer World Cup.

But 2024’s climate talks are more like the International Chess Federation world championship, lacking recognizable names but big on nerd power and strategy. The top leaders of the 13 largest carbon dioxide-polluting countries will not appear. Their nations are responsible for more than 70% of 2023’s heat-trapping gases.

The world’s biggest polluters and strongest economies — China and the United States — aren’t sending their No. 1s. India and Indonesia’s heads of state are also not in attendance, meaning the four most populous nations with more than 42% of all the world’s population aren’t having leaders speak.

“It’s symptomatic of the lack of political will to act. There’s no sense of urgency,” said climate scientist Bill Hare, CEO of Climate Analytics. He said this explains “the absolute mess we’re finding ourselves in.”

Transition to clean energy

The world has witnessed the hottest day, months and year on record “and a master class in climate destruction,” United Nations Secretary-General Antonio Guterres told the world leaders who did show up.

But Guterres held out hope, saying, in a veiled reference to Donald Trump’s re-election in the United States, that the “clean energy revolution is here. No group, no business, no government can stop it.”

United Nations officials said in 2016, when Trump was first elected, there were 180 gigawatts of clean energy and 700,000 electric vehicles in the world. Now there are 600 gigawatts of clean energy and 14 million electric vehicles.

Host Azerbaijan President Ilham Aliyev kicked off two scheduled days of world leaders’ speeches by lambasting Armenia, western news media, climate activists and critics who highlighted his country’s rich oil and gas history and trade, calling them hypocritical since the United States is the world’s biggest oil producer. He said it was “not fair” to call Azerbaijan a “petrostate” because it produces less than 1% of the world’s oil and gas.

Oil and gas are “a gift of the God” just like the sun, wind and minerals, Aliyev said. “Countries should not be blamed for having them. And should not be blamed for bringing these resources to the market because the market needs them.”

As the host and president of the climate talks, called COP29, Aliyev said his country will push hard for a green transition away from fossil fuels, “but at the same time, we must be realistic.”

Lack of star power

Aliyev, United Kingdom’s Prime Minister Keir Starmer and Turkey’s President Recep Tayyip Erdogan are the headliners of around 50 leaders set to speak on Tuesday.

There’ll also be a strong showing from the leaders of some of the world’s most climate-vulnerable countries. Several small island nations presidents and over a dozen leaders from countries across Africa are set to speak over the two-day World Leaders’ Summit at COP29.

As a sense of how the bar for celebrity has lowered, on Tuesday morning photographers and video cameras ran alongside one leader walking through the halls of the meeting. It was the emergency management minister for host country Azerbaijan.

United Nations officials downplayed the lack of head of state star power, saying that every country is represented and active in the climate talks.

One logistical issue is that next week, the leaders of the most powerful countries have to be half a world away in Brazil for the G20 meetings. The United States recent election, Germany’s government collapse, natural disasters and personal illnesses also have kept some leaders away.

The major focus of the negotiations is climate finance, which is rich nations trying to help poor countries pay for transitioning their economies away from fossil fuels, coping with climate change’s upcoming harms and compensating for damages from weather extremes.

Nations are negotiating over huge amounts of money, anywhere from $100 billion a year to $1.3 trillion a year. That money “is not charity, it’s an investment,” Guterres said.

“Developing countries must not leave Baku empty-handed,” Guterres said. “A deal is a must.”

MEXICO CITY — Cassandra Garduño squinted in the sunlight, her pink boots smudged by dirt as she gazed out over her family’s chinampa — one of the islands first built up by the Aztecs with fertile mud from the bottom of a lake that, later drained, would one day become Mexico City.

Food from these islands has fed people for hundreds of years, but the chinampas are under threat from urbanization. The produce grown here doesn’t fetch much money, and many families are abandoning the ancient practice to rent out or sell their land for more lucrative uses such as soccer fields.

“People don’t want to farm anymore,” said Garduño. “They don’t see it as a necessity, they don’t want to produce, and people don’t want to buy the products.”

Some of those remaining, like Garduño, are banding together to preserve and promote the traditional use of the chinampas.

“None of this can exist without human hands, the hands of those who worked here and created the chinampa a thousand years ago,” she said on a recent morning as the smell of celery growing nearby filled the air.

The gardens crisscrossed by canals in the capital’s southern Xochimilco borough are built up from layers of dredged soil, held together by tall, thin ahuejotes — a kind of willow tree — planted around their perimeter. Xochimilco has more than 2,500 acres of protected land owned by generations of local chinamperos, as those who farm the islands are known.

Garduño’s earliest memories of her family’s chinampa came from peering through her grandparents’ window at the plot of land and watching canoes weave in and out of the canals. Even then, she saw how the chinampas were deteriorating under pressure from urbanization and as some farmers began to drop the practice.

When her grandfather died in 2010 and her uncles didn’t want to carry on, Garduño took it upon herself to learn and conserve generations of farming. Her neighbors and relatives were skeptical at first, but she bought land for her own chinampa from a friend’s uncle in 2020 and now grows an assortment of produce, including sunflowers, eggplant, and the Mexican marigold “cempasuchil.”

Now the 32-year-old Garduño is one of the growing collective called Chinampa Refuge, started by the National Autonomous University of Mexico, and she and other famers encourage chinamperos to preserve their land. They follow ancient growing techniques but are trying new commercial approaches to compete with cheaper produce grown on massive farms elsewhere in Mexico. That includes a special tag — Etiqueta Chinampera — that tells buyers the produce came from a chinampa, and may tout things like water quality or the chinampa’s status as a biodiversity refuge.

“Change comes with educating the new generations,” said Garduño. “Talking about the origins and efforts to conserve and why it’s important to do it.”

Luis Zambrano, an ecologist from the National Autonomous University of Mexico who has worked in Xochimilco for decades, said the fields are largely self-sustaining. Nourished by the lake, they can produce three to five crops of vegetables a year without the need of chemicals or irrigation, he said.

Moreover, the ecosystem of Xochimilco benefits the sprawling city. Many different species of birds and fish thrive there, and the extensive canals help reduce the city’s overall temperature, he said.

But now, on weekends, it’s common to see more soccer players boating to islands in their jerseys and cleats than farmers tending their crops. The soccer fields stretch for miles along the canals after what Zambrano called “a massive increase” over the past two to three years.

In Xochimilco, many people are reluctant to talk about transforming their chinampas to soccer fields. One landowner who declined to be identified for fear of legal or community backlash said keeping the chinampas productive required more work and financial investment and yielded less revenue. Instead, she has established multiple businesses on her land — a soccer field for weekend games, a food stand and kayaking tours for foreign visitors.

“If you do well (farming) you could earn $5,000 to $10,000 (100,000 to 200,000 pesos) a year,” Garduño said. “In the tourist area you could have that within a couple of weekends.”

But converting the agricultural fields carries ecological impact. While traditional farming methods avoid insecticides and fertilizers, the soccer fields are another story.

“It doesn’t look that detrimental because there’s no construction,” said Zambrano. But “it’s just as damaging because the amount of chemicals that are used, the amount of pollution that is generated is very, very large.”

The chinampas are among the significant features that led Mexico City’s historic center and Xochimilco to be recognized as a world heritage site by UNESCO. But any protective measures are up to federal, state and local authorities. Carlos Vasquez, director of the Natural Protected Areas under Mexico City’s Environmental Department, said they are working on proposals to address the soccer fields.

“Many are counter to the conservation of the ecosystems,” he said. “We’re looking to regulate these activities.”

After a long day’s work out in the sun, Garduño and some neighboring farmers congregate under Garduño’s makeshift hut for a feast of chicken and tortillas. They catch up on their tasks and outline what’s left to do.

Juan Ávalos, 63, and his brother Salvador Gonzalez Ávalos, 55, have been working on chinampas all their lives. Their family has several plots in Xochimilco’s San Gregorio neighborhood. A year ago, after some convincing by Garduño, the brothers joined Chinampa Refuge to adopt a more holistic approach to their farming.

Salvador said the approach is a continuous reminder of his family’s legacy in maintaining the ancient practices — something they want to pass on to their grandchildren.

“That’s something we need to work on as grandparents,” he said. “That they integrate themselves with a taste for this earth.”

OTTAWA, Ontario — Canada has detected its first presumptive case of H5 bird flu in a person, a teenager in the western province of British Columbia, health officials said Saturday.

The teenager likely caught the virus from a bird or animal and was receiving care at a children’s hospital, the province said in a statement.

The province said it was investigating the source of exposure and identifying the teenager’s contacts. The risk to the public remains low, Canada’s Health Minister Mark Holland said in posting on X.

“This is a rare event,” British Columbia Health Officer Bonnie Henry said in a statement. “We are conducting a thorough investigation to fully understand the source of exposure here in B.C.”

H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows, with several recent human cases in U.S. dairy and poultry workers.

There has been no evidence of person-to-person spread so far. But if that were to happen, a pandemic could unfold, scientists have said.

Earlier in November, the U.S. Centers for Disease Control and Prevention asked for farm workers who have been exposed to animals with bird flu to be tested for the virus even if they do not have symptoms.
