Singapore targets net zero by 2050, eyes hydrogen power

Low-lying Singapore is seen as especially vulnerable to rising sea levels

Singapore announced Tuesday it aims to achieve carbon neutrality by 2050, giving a firm date for the first time, and will look at using hydrogen as a major power source.

The city-state targets for carbon emissions to peak in 2030 at 60 million tonnes, a reduction of five million tonnes from the previous goal, Deputy Prime Minister Lawrence Wong said.

The Southeast Asian nation also has plans to look at developing low carbon hydrogen as a major power supply in the long term.

“If technology continues to advance, we foresee that hydrogen can supply up to half of our power needs by 2050, alongside domestic renewable energy sources and electricity imports,” Wong said at an industry conference.

He added that Singapore would experiment with key hydrogen technologies to see how it can be implemented on a large scale.

“We do not have the land for large solar or wind farms, or fast flowing rivers for hydro-electric power,” said Wong, the country’s prime minister in waiting.

Green hydrogen is in sharp focus as governments seek to slash carbon emissions amid global warming and to safeguard energy supplies hit by the invasion of Ukraine by oil and gas producer Russia.

But the “hydrogen economy” has not fully kicked into gear awaiting significant uptake from high-polluting sectors like steel and aviation.

“Many hydrogen technologies are still under development, and a global supply chain has yet to be established,” the Singapore government said in a statement.

“Nevertheless, there has been strong interest internationally from the public and private sectors to accelerate the development,” it added.

Prime Minister Lee Hsien Loong has said the low-lying island nation is especially vulnerable to rising sea levels and defending it from the threat is “existential”.

16 dead, million seek shelter as cyclone hits Bangladesh

Bangladesh authorities managed to evacuate around a million people from their homes before Cyclone Sitrang hit

At least 16 people died after a cyclone slammed into Bangladesh, forcing the evacuation of about a million people from their homes, officials said Tuesday.

Around 10 million people were without power in 15 coastal districts, while schools were shut across southern and southwestern regions.

Cyclones — the equivalent of hurricanes in the Atlantic or typhoons in the Pacific — are a regular menace but scientists say climate change is likely making them more intense and frequent.

Cyclone Sitrang made landfall in southern Bangladesh late Monday but authorities managed to get about a million people to safety before the monster weather system hit.

Jebun Nahar, a government official, said 14 people died, mostly after they were hit by falling trees, and two died after a boat sank in squally weather in the Jamuna river in the north. 

“We still have not got all the reports of damages,” she told AFP.

People evacuated from low-lying regions such as remote islands and river banks were moved to thousands of multi-storey cyclone shelters, Disaster Management Ministry secretary Kamrul Ahsan told AFP.

“They spent the night in cyclone shelters. And this morning many are heading back to their homes,” he said.

In some cases police had to cajole villagers who were reluctant to abandon their homes, officials said.

Trees were uprooted as far away as the capital Dhaka, hundreds of kilometres (miles) from the epicentre of the storm.

Heavy rains lashed much of the country, flooding cities such as Dhaka, Khulna and Barisal — which witnessed 324 millimetres (13 inches) of rainfall on Monday.

About 33,000 Rohingya refugees from Myanmar, controversially relocated from the mainland to a storm-prone island in the Bay of Bengal, were ordered to stay indoors and there were no reports of any casualties or damage, officials said.

A feared major storm surge did not materialise, however.

– Panic and snakes –

On the southern island of Maheshkhali, the cyclone uprooted many trees and created panic after power and telecoms were cut.

“Such was the power of the wind we could not sleep in the night because of the fear that our homes will be destroyed. Snakes entered many homes. Water also inundated many homes,” said Tahmidul Islam, 25, a resident of Maheshkhali.  

In the worst-affected Barisal region, teeming rains and heavy winds wreaked havoc for vegetable farms, Aminul Ahsan, regional district administrator, told AFP.

In the neighbouring eastern Indian state of West Bengal, thousands of people were evacuated Monday to more than 100 relief centres, officials said, but there were no reports of damage and people were returning home on Tuesday.

Last year, more than a million people were evacuated along India’s east coast before Cyclone Yaas battered the area with winds gusting up to 155 kilometres (96 miles) an hour — equivalent to a Category 2 hurricane.

Cyclone Amphan, the second “super cyclone” ever recorded over the Bay of Bengal, which hit in 2020, killed more than 100 people in Bangladesh and India, and affected millions.

In recent years, better forecasting and more effective evacuation planning have dramatically reduced the death toll from such storms. The worst recorded, in 1970, killed hundreds of thousands of people.

Will Africa's metals boom suffer the same curse as oil?

Mineral wealth: the Moanda region in Gabon may hold as much as a quarter of the world's known deposits of manganese

Mechanical diggers are hard at work in the bleak landscape of the Moanda open-cast mine in Gabon, using giant jaws to rip out manganese and then dump the ore into trucks with a crash.

“We’re lucky here in Moanda. We find it about five to six metres (about 18 feet) below the surface,” said manager Olivier Kassibi, whose mine yields 36 tonnes of manganese each day.

Element number 25 on the periodic table, manganese has traditionally been perceived as a useful if humdrum material widely employed in steel and alloys.

More recently, though, the silvery metal has gained star status thanks to its emerging role in rechargeable car batteries, helping to wean the world off carbon-spewing fossil fuels.

Decarbonisation of the world economy will take centre stage at the UN’s COP27 climate talks in Egypt next month.

And as the great transition goes into higher gear, eyes are turning to Africa.

Its soil is rich in manganese, cobalt, nickel and lithium — crucial ingredients in cleaner technology for generating or storing power.

The Moanda region alone contains as much as a quarter of known global reserves of manganese, according to the Compagnie Miniere de l’Ogooue (Comilog), a subsidiary of the French group Eramet which operates the site.

– Curse of oil –

But hopes that the mineral boom will translate into a new dawn of prosperity in the world’s poorest continent are clouded by memories of what happened with oil.

In Africa’s oil-producing countries, black gold meant a gush of wealth for a well-connected few — but only drops for the needy majority.

Corruption sucked the dollars out of plans for roads, hospitals and schools, and environmental damage was often all that remained.

Africa’s potential in new-age minerals is “huge”, said the former chief economist of the African Development Bank, Rabah Arezki, who pointed out that reserves are not even known because so little exploration has been done.

But, he said, “there is very little reason to think that this windfall will benefit the people of Africa, particularly because of governance concerns.”

New metals deposits are following one another at a giddying pace.

In one example, Firefinch Ltd of Australia was looking for gold at Goulamina in southern Mali when it came across lithium, said Seydou Semega, geologist and local director of the firm.

Firefinch then created a local offshoot, Leo Lithium, and inaugurated the mine in early 2022 — a facility that it says could create 1,200 jobs and generate more than $100 million a year for Mali in taxes and dividends.

“Could Africa be the main source of lithium in the world?” asked Simon Hay, director of Leo Lithium. “Absolutely.” 

Comilog, which has operated the Moanda mine since 1960, claims the creation of 3,400 direct and 6,000 indirect jobs, a contribution of around $345 million per year to the national economy in various forms, plus millions of dollars in health and education provisions for the population.

“You need to have a social policy that is as committed as possible to share this wealth,” said its CEO, Leod Paul Batolo.

Comilog is keen to list its green principles, which include rehabilitating and replanting extraction sites, decarbonising the energy mix of its factories and “setting limits” on encroaching on wildlife areas.

But more generally, innumerable studies say the exploitation of resources in Africa has a long and dark history of unequal distribution of wealth, corruption, environmental damage and rights violations.

– ‘Value chain’ –

A big problem is that Africa is typically used as a source of raw materials, and rarely for processing them into goods of higher value, said Gilles Lepesant, a geographer at the French National Centre for Scientific Research (CNRS).

“If activity is limited to mining and extracting ore, Africa will reap no benefit from the energy transition in Europe. It’s absolutely necessary to invest in the value chain,” he said.

He pointed to the Democratic Republic Congo, whose soil is estimated to contain half of the world’s reserves of cobalt, as an example of something that is “both an opportunity and a curse.”

Poorly regulated mining leads to environmental damage and encourages child labour, a phenomenon that is hard to resolve when a family’s livelihood depends on it.

In the sector of tropical forestry, many rich countries have demanded traceability of wood and labour in order to reassure concerned consumers. 

But this is far harder to achieve in the metals used in car batteries and other gadgets, said Lepesant.

“In a lot of cases, the mined metal is exported for refining to other countries, for example China, and then combined with other metals, so it’s hard to know if the cobalt you have on your production line actually comes from such and such a mine in the Democratic Republic of Congo,” he said.

Analyst Hugo Brennan of British firm Verisk Maplecroft said African nations had to strike “a tricky balancing act” — providing incentives for investment while enforcing social and environmental standards — to ensure their mining boom does not go the same way as oil.

Activists see red over Iceland's blood mares

Pregnant mares stand in the meadow of a 'blood farm' near Selfoss, Iceland, Animal — but animal welfare groups are up in arms about the practice

On an autumn day on a lush green prairie, more than a dozen pregnant mares are waiting to be bled for the last time this year.

This “blood farm” near Selfoss in southern Iceland is collecting blood from pregnant horses raised for the sole purpose of extracting a special hormone used in the veterinary industry.

The practice has had animal welfare groups up in arms ever since a shocking video of horses in Iceland being maltreated emerged on YouTube a year ago. 

People working in the industry now insist on anonymity when speaking to the media.

“There is no way we can make the public understand completely this kind of farming”, says the 56-year-old owner of the farm near Selfoss.

“The public in general is too sensitive”.

At farms like this one, several litres of blood are collected from each horse in order to extract the PMSG hormone (Pregnant mare serum gonadotropin), also known as eCG, produced naturally by pregnant mares.

Sold by the veterinary industry, farmers use the hormone to improve the fertility of other livestock like cows, ewes and sows around the world.

The foals are meanwhile usually sent to the slaughterhouse. 

Iceland is one of the rare countries — and the only one in Europe — to carry out the controversial practice, along with Argentina and Uruguay, and to a lesser extent Russia, Mongolia and China.

The video published last year showed farmhands beating and prodding horses with sticks, dogs sometimes biting horses, and the horses weakened after giving blood. 

Some of the horses could be seen collapsing from exhaustion after struggling against the restraints in their boxes. 

The video caused a shockwave, both abroad and in Iceland.

– Lucrative business –

At the farm near Selfoss, the mares stand in single file in a special wooden structure, waiting patiently for their turn to enter a box. 

Planks are placed around their legs to prevent them from moving and a halter is put on their head to hold it up.

“The horses … can get stressed, agitated. All these restraints are basically to protect them” so they don’t get hurt in the box, said a 29-year-old Polish veterinarian, also speaking on condition of anonymity.

A local anaesthetic is first administered, then a large needle is injected into the jugular vein. Only a certified veterinarian is authorised to carry out the procedure.

The halter “allows us to see the vein properly because we need to know exactly where it is”, he added.

Up to five litres of blood are drawn from each mare in just a few minutes, in an operation they undergo weekly for eight weeks.

The blood collection, carried out from the end of July until early October, is profitable: the 56-year-old running the operation near Selfoss — who also works as an attorney — makes up to 10 million kronur ($70,000) a year from the business.

“In many cases, the mares show signs of short-term discomfort during the blood collection”, says Sigridur Bjornsdottir, a horse specialist at the Icelandic Food and Veterinary Authority (MAST).

But “this is not considered a serious change (of their condition) unless the symptoms are severe, extended, or the mare shows signs of chronic stress”.

In 2021, Iceland had 119 blood farms and almost 5,400 mares raised for the sole purpose of giving blood, a figure that has more than tripled in the past decade.

The PMSG hormone is turned into a powder by Icelandic biotech group Isteka, the biggest producer in Europe handling around 170 tonnes of blood per year. 

– ‘Noble’ cause? –

The figure is likely to be lower this year, after the controversial video prompted some farmers to quit the business amid concerns about animal welfare activists.

“Farmers were severely hit and shocked by the video”, said Isteka managing director Arnthor Gudlaugsson.

While he acknowledged there were problematic cases, Gudlaugsson said the video, filmed with a hidden camera, was designed “to give an overly negative description of the process”.

The video did lead to a police investigation and the farms featured were identified. 

MAST inspected all of Iceland’s blood farms this summer and “no serious deviations” were observed, and none were ordered to shut down.

The scandal has also sparked debate in Iceland, where most inhabitants learned about the practice for the first time even though it has been going on since 1979.

“This makes us think about where we stand in our ethics”, the vice chair of Animal Welfare Iceland, Rosa Lif Darradottir, told AFP.

“To make a fertility drug that is used on farm animals … to enhance their fertility beyond their natural capacity, just so that we can have a stable flow of cheap pork … The cause is not noble”, she said.

Opponents also criticise the amount of blood collected. 

“It’s purely and simply maltreatment of animals and we have a word for that: animal cruelty”, said opposition MP Inga Saeland, who has repeatedly proposed a ban on the practice, to no avail.

Stricter regulations did, however, enter into force in August, giving authorities more power to monitor the industry and “assess its future” over the next three years. 

'We don't eat lithium': S. America longs for benefits of metal boon

In South America, lithium is derived from salars, or salt flats

The turquoise glimmer of open-air pools contrasts sharply with the dazzling white of salt flats in Latin America’s “lithium triangle,” where hope resides for a better life fueled by a metal bonanza.

A key component of batteries used in electric cars, demand has exploded for lithium — the “white gold” found in Chile, Argentina and Bolivia in quantities larger than anywhere else in the world.

And as the world seeks to move away from fossil fuels, lithium production — and prices — have skyrocketed, as have the expectations of communities near lithium plants, many of whom live in poverty.

But there are growing concerns about the impact on groundwater sources in regions already prone to extended droughts, with recent evidence of tree and flamingo die-offs.

And there are scant signs to date of benefits trickling down.

“We don’t eat lithium, nor batteries. We do drink water,” said Veronica Chavez, 48, president of the Santuario de Tres Pozos Indigenous community near the town of Salinas Grandes in Argentina’s lithium heartland.

A poster that meets visitors to Salinas Grandes reads: “No to lithium, yes to water and life.”

Lithium extraction requires millions of liters of water per plant per day.

Unlike in Australia — the world’s top lithium producer that extracts the metal from rock — in South America it is derived from salars, or salt flats, where saltwater containing the metal is brought from underground briny lakes to the surface to evaporate.

– Soaring prices –

About 56 percent of the world’s 89 million tons of identified lithium resources are found in the South American triangle, according to the US Geological Survey (USGS).

The world average price rose from $5,700 per ton in November 2020 to $60,500 in September this year. 

Chile hosts the westernmost corner of the lithium triangle in its Atacama desert, which contributed 26 percent of global production in 2021, according to the USGS.

The country started lithium extraction in 1984 and has been a leader in the field partly because of low rainfall levels and high solar radiation that speeds up the evaporation process.

But Chilean law has made it difficult for companies to gain concessions from the government since the dictatorship of Augusto Pinochet declared the metal a “strategic resource” for its potential use in nuclear bombs.

Only two companies have permits to exploit the metal — Chile’s SQM and American Albemarle, which pay up to 40 percent of their sales in tax.

In the first quarter of this year, lithium’s contribution to the public coffers surpassed those of Chile’s mainstay metal, copper, for the first time, according to government records.

Yet, the environmental costs are starting to stack up, and locals fear there is worse to come.

This year, a study in the journal Proceedings of the Royal Society B found a link between lithium mining and a decline in two flamingo species in the Salar de Atacama.

“The development of technologies to slow climate change has been identified as a global imperative. Nonetheless, such ‘green’ technologies can potentially have negative impacts on biodiversity,” said the study.

In 2013, an inspection at the SQM site — which reported using nearly 400,000 liters of water per hour in 2022 — found that a third of carob trees in the area had died.

A later study pointed to water scarcity as a possible cause.

“We want to know, for sure, what has been the real impact of the extraction of groundwater,” said Claudia Perez, 49, a resident of the nearby San Pedro river valley.

She was not against lithium, said Perez, provided there are measures to “minimize the negative impact on people.”

– ‘Leave us alone’ – 

Across the Andes in Argentina, the salt lakes of Jujuy host the world’s second-largest lithium resources along with the neighboring provinces of Salta and Catamarca.

With few restrictions on extraction and a low tax of only 3.0 percent, Argentina has become the world’s fourth-biggest lithium producer from two mines.

With dozens of new projects in the works with the involvement of US, Chinese, French, South Korean and local companies, Argentina has said it hopes to exceed Chilean production by 2030.

But not everyone is sold on the idea.

“It is not, as they say, that they (lithium companies) are going to save the planet… Rather it is us who have to give our lives to save the planet,” said Chavez, of Santuario de Tres Pozos in Jujuy province.

A neighbor, 47-year-old street food seller Barbara Quipildor added fiercely: “I want them to leave us alone, in peace. I don’t want lithium… My concern is the future of my children’s children.”

– Will locals benefit? –

About 300 kilometers (190 miles) north of Jujuy, the salar of Uyuni in Bolivia holds more lithium than anywhere else — a quarter of global resources, according to the USGS.

Half of the residents in the region — which is also rich in silver and tin — live in poverty, household surveys show.

The country’s former leftist president Evo Morales nationalized hydrocarbons and other resources such as lithium towards the start of his 2006-2019 mandate and vowed Bolivia would set the metal’s global price.

In Rio Grande, a small town near the Yacimientos de Litio Bolivianos (YLB) lithium plant, Morales’ plans were met with excitement.

In 2014 Donny Ali, a lawyer now aged 34, opened a hotel with the expectation of an economic boom. 

He called it Lithium.

“We were expecting major industrial technological development and more than anything, better living conditions,” he told AFP. “It didn’t happen.”

Hoping to boost the struggling lithium sector, the government opened it up to private hands in 2018, though domestic legislation has not yet denationalized the resource, and no private extraction has yet begun. 

“Some think that Bolivia will ‘miss the boat’ of lithium,” said economist Juan Carlos Zuleta. “I don’t think that’s going to happen.”

The real question, he said, is: when the boat comes, “will lithium extraction benefit Bolivians?”

The three countries are now looking towards battery manufacturing — possibly even building electric cars — as a way to turn the natural lithium bounty into a modern-day industrial revolution.

“There is a concrete possibility for Latin America to become the next China,” said Zuleta.

In the meantime, the Hotel Lithium stands empty.

Nine dead, million seek shelter as cyclone hits Bangladesh

Bangladesh authorities managed to evacuate around a million people from their homes before Cyclone Sitrag hit

At least nine people have died after a cyclone slammed into Bangladesh, forcing the evacuation of around a million people from their homes, officials said Tuesday.

Cyclones — the equivalent of hurricanes in the Atlantic or typhoons in the Pacific — are a regular menace but scientists say climate change is likely making them more intense and frequent.

Cyclone Sitrang made landfall in southern Bangladesh late Monday but authorities managed to get about a million people to safety before the monster weather system hit.

“Nine people have died, most by trees falling including three from one family in (the eastern district of) Cumilla”, Jebun Nahar, a government official, told AFP.

People evacuated from low-lying regions such as remote islands and river banks were moved to thousands of multi-storey cyclone shelters, Disaster Management Ministry secretary Kamrul Ahsan told AFP.

“They spent the night in cyclone shelters,” he said.

In some cases police had to cajole villagers who were reluctant to abandon their homes, officials said.

Heavy rains lashed much of the country, flooding cities such as Dhaka, Khulna and Barisal — which witnessed 324 millimetres (13 inches) of rainfall on Monday.

About 33,000 Rohingya refugees from Myanmar, controversially relocated from the mainland to a storm-prone island in the Bay of Bengal, were ordered to stay indoors and there were no reports of any casualties or damage, officials said.

In the neighbouring eastern Indian state of West Bengal, thousands of people were evacuated Monday to more than 100 relief centres, officials said, but there were no reports of damage and people were returning home on Tuesday.

Cyclone Amphan, the second “super cyclone” ever recorded over the Bay of Bengal, which hit in 2020, killed more than 100 people in Bangladesh and India, and affected millions.

In recent years, better forecasting and more effective evacuation planning have dramatically reduced the death toll from such storms. The worst recorded, in 1970, killed hundreds of thousands of people.

Food shock: Crop-battering disasters highlight climate threat

Deadly monsoon inundations in Pakistan engulfed vast swathes farmland

Rolling crises linked to war, weather disasters and the pandemic have shaken global food systems and tipped millions into hunger and poverty.

Climate change is already playing a role, as floods, droughts and heatwaves batter harvests from Europe to Asia and threaten famine in the Horn of Africa. 

And experts warn this could be just the beginning. 

“If we don’t act now, this is just a sample of what may happen in the coming years,” said Mamadou Goita, an expert with sustainability group IPES-Food, which works with farmers’ organisations in Africa and around the world. 

This issue will be in focus as never before at high-stakes UN climate negotiations, to be held in Egypt next month.

Food production is both a key source of planet-warming emissions and highly exposed to the effects of climate change.

Some risks are slow-burning — falling yields, warming oceans, seasonal mismatches between pollinators and plants, and heat threats to farm workers. 

Others, like floods, can cause sudden “devastation of livelihoods and infrastructure”, said Rachel Bezner Kerr, professor at Cornell University and a lead author of the UN’s landmark IPCC report on climate impacts.  

These can reverberate through interwoven global supply chains, intersecting with other crises.

Climate extremes and Covid-19 had already pushed food costs close to record highs early this year, when Russia invaded Ukraine — a key grain and sunflower oil exporter.

Since then, record temperatures withered crops across South Asia, the worst drought in 500 years savaged Europe’s maize and olive crops, heat scorched cabbages in South Korea sparking a “kimchi crisis”, and floods swamped Nigeria’s rice fields. 

In China, as a punishing dry spell parched the Yangtze river basin where a third of its crops are grown, authorities sent up cloud-seeding drones to try and coax rain.

– ‘Persistent peril’ –    

Those most vulnerable are hit hardest.

The UN’s World Food Programme has said some 22 million people are at risk of starvation across Kenya, Somalia and Ethiopia, after an unprecedented four failed rainy seasons.

Globally, one person is estimated to starve to death every four seconds, nearly 200 aid groups reported in September, while a record 345 million people are suffering from acute hunger. 

“It does feel like our report is being lived out in real time,” said Bezner Kerr.

Fifty countries are severely affected by the global food crisis, according to the International Monetary Fund.

Among them is flood-hit Pakistan, where deadly monsoon inundations engulfed vast swathes of farmland, ravaging staple crops such as rice, tomatoes and onion. Two percent of the country’s livestock perished.  

In Mirpur Khas district of agricultural powerhouse Sindh province, water swallowed Akbar Rajar’s cotton crop and pooled for weeks on his fields.

“We are in persistent peril,” the heavily indebted farmer told AFP, preparing to plant wheat in sodden ground. 

Up to nine million people could be dragged into poverty by the disaster, the World Bank says.

– ‘Betting frenzy’ –

The world grows plenty of food for everyone, but lack of access and affordability prevent its distribution, experts say. 

“Once there is any problem, like Covid-19, they have been closing doors to everybody,” Goita told AFP. 

Changes to global food systems in recent decades mean countries rely less on stocks of staple crops, with about a third of food and agricultural production now traded internationally. 

That is cost-effective when things go well, but is “highly vulnerable” to major shocks, said Elizabeth Robinson, who leads the Grantham Research Institute at the London School of Economics. 

“Who gets harmed? You’re looking at countries where people spend a lot of money on food, where countries are highly dependent on imports.”

Shocks can lead to export restrictions, like those imposed by India this year when its wheat harvest was hit by the heat wave.

Importers have also been hammered by surging energy and transport costs and a strong US dollar, while the UNCTAD trade and development agency has warned of “betting frenzies” in commodities markets. 

Fertiliser prices have surged, raising concerns for future harvests.

The last time the UN Food and Agriculture Organization’s food price index was this high was in 2008, when a global food crisis drove riots and instability in countries across the world. 

So what should be on the table at the Egypt climate talks? 

One answer is money, particularly for smallholder farmers on the climate change and food insecurity “frontlines”, said Claire McConnell of think tank E3G. 

Just two percent of climate finance reaches them, she said, adding that in Africa and the Middle East alone there is a $1.7 billion funding gap for the support and technology needed.

– Strength in diversity –

Another is emissions cuts. Food production will become “impossible” in some regions, and both hunger and malnutrition will deepen if warming continues its current trajectory, the IPCC has said.

Redirecting billions of dollars of agricultural subsidies that incentivise environmental harm would also make a big difference, said Bezner Kerr. 

People in richer nations could cut their meat consumption to reduce the grain needed to feed livestock, while nations everywhere could consider broadening their taste for staples beyond rice, maize, wheat and potatoes.  

That may resonate in COP host Egypt, where most of the wheat for cheap state-subsidised flatbread — a lifeline for around 70 percent of the population — is ordinarily imported from Ukraine and Russia.    

Facing surging inflation, the government has ramped up purchases from domestic farmers, and is even running a trial adding sweet potato to bread flour.

Diversifying crops and using more drought- or flood-resilient strains could also help farmers improve soils and spread risk.    

But such solutions have limits.   

Pakistan’s floods tore over fields, ripping plants up by the root, said Nabeel Munir, the country’s ambassador to Seoul and chair of the largest negotiating bloc of developing nations at the climate talks. 

“How can you produce a crop that, even after being blown away and submerged in water for a few days, is still resistant?” he said.

For blight-ridden American chestnut tree, rebirth may be in offing

If scientists are successful, American chestnut trees will recover from a terrible blight that has devastated the species

The American chestnut tree, once a regal pillar of forests across the eastern United States, is on life support, struggling to survive.

“These look like death,” said Vasiliy Lakoba, research director for the American Chestnut Foundation (ACF), which has been working since the 1980s to resurrect the species.

He pointed to a patch of stunted shrubs, chestnut trees that were a far cry from the noble, erect chestnut trees of yesteryear.

Settlers along the US eastern seaboard relied on abundant chestnut trees to feed their hogs, their children and themselves. Chestnuts made up about 50 percent of hardwood forests in much of the eastern seaboard, and the wood was ideal for building.  

But then came a terrible fungus, identified in 1904 at the Bronx Zoo on a tree from Japan. In less than three decades, millions of American chestnut trees had perished. It has been considered the greatest tragedy in the history of American forestry.

“The devastation was so fast,” said Lakoba, referring to “ghost forests.”

Today, only a few rare specimens still survive to adulthood in the wild.

– ‘Tall and straight’ –

Nestled in the Appalachian Mountains, the foundation’s main laboratory farm spans 36 hectares (almost 90 acres) in Virginia and includes tens of thousands of trees.

Workers use a crane to harvest the burrs, or spiny prickly shells that cover the nuts, then take them to a shed to be studied and used for future planting.

“It’s like picking apples, but with pricks,” laughed Jim Tolton, a technician on the farm, during a chestnut harvest day in early October.

Before the disease, the American chestnut tree “grew tall and straight through the forest, fighting for light,” Lakoba said.

But the blight causes cankers to appear on the branches and stems of the American chestnut tree.

Blighted trees grow other branches here and there, giving them a bushy appearance, instead of maintaining a tall, straight shape.

No cure has yet been found to stop the spread.

– Hybrids and GMOs –

Finding a way to fight the blight is precisely the mission of ACF.

To do this, two main research avenues are under investigation: The first, which has been in place for years, consists of crossing an American chestnut tree with other species that already show some resistance to the fungus, such as the Chinese chestnut tree. 

A first specimen is produced from this hybridization, before it is crossbred again with an American chestnut tree, then once again — all in order to preserve as much of the original genetic characteristics as possible. The current hybrid has 15/16ths of the genetic makeup of an American chestnut tree — while ideally acquiring the resistance of the Chinese chestnut tree.

One of the main drawbacks with these hybrids, explained Lakoba, “is that blight resistance and susceptibility have turned out to be a genetically much more complex phenomenon than previously thought.”

ACF researchers have not abandoned their crossbreeding efforts. But a second avenue of research has opened up: genetic modification.

Working on a transgenic version of the American chestnut tree, researchers at the State University of New York at Syracuse have developed a specimen that shows very promising early results of disease resistance, according to Lakoba, who is collaborating with the researchers.

Combining crossbreeding with genetic modification might yield better results, he said.

– ‘Keep chipping away’ –

Once a resistant specimen has been developed, the time will come for the Herculean task of reintroducing the tree to an American landscape deeply altered by more than a century of development.

“So much has changed in terms of climate, in terms of invasive species, in terms of pollution, habitat change, land use, change, soil loss and erosion, that it really isn’t the same world from 100 years ago,” Lakoba said.

Not only has the landscape been altered, Lakoba said, climate change adds another wildcard to whether the American chestnut can ever prosper again.

“Overall, there will be more pests, there will be more diseases,” he said.

Any revival of the American chestnut may be decades — or centuries — away.

“This is definitely at least a couple centuries of a mission going forward. And from there, I think we just keep chipping away at it,” Lakoba said. 

But he is hopeful that scientific advances are on the side of the American chestnut.

“We see it really as a matter of time.”

Will climate change doom US truck habit? Detroit says no

Like other electric vehicles being developed by Detroit, Ford Motor Co.'s F-150 Lightning has been praised as an improvement in addressing climate change, although it requires more energy to recharge than does a smaller vehicle

The US consumer’s love for enormous vehicles has been seen by outsiders as a curiosity and sometimes a sign of profligacy.

Either way, rising concerns about climate change seemed to create a reckoning for the behemoth-sized pickup trucks and sport utility vehicles that recently have sustained US automaker profits.

Not so, according to Detroit auto giants, who have responded to the climate crisis by launching all-electric versions of the Ford F-150 pickup, the Chevrolet Blazer SUV and other best-selling giants that seemingly promise the possibility that consumers can have it all: address global warming without sacrificing the appeal of larger autos.

Leading US environmentalists, along with the Biden administration, have praised announcements of the electric vehicle (EV) rollouts as a way to reduce greenhouse gas emissions.

Absent has been any discussion of the environmental toll of large EV trucks, which require more energy to recharge and more critical materials than do smaller EVs.

In showcasing trucks, Detroit automakers are setting the groundwork for an EV era that mirrors the current profile of US roadways and distinct from Europe, where sedans dominate.

Industry insiders like Alan Amici, president of the Center for Automotive Research, see little appetite among American consumers to go small.

“People are still clamoring for big pickups and SUVs,” Amici said. “I don’t expect a return to sedans.”

The trucks, often marketed in advertisements navigating rugged landscapes, provide lucrative profit margins to automakers and have become so ubiquitous on US roads that some consumers avoid smaller vehicles out of fear of how it would handle a crash with a much bigger auto.

Ford and General Motors, both of which report earnings this week, are positioning the vehicles as environmentally friendly based on how they contrast with gas-guzzling equivalents.

Luke Tonachel, who heads the clean vehicles program at environmental group NRDC, said electric pickups and SUVs represent a critical step in addressing climate change.

“It’s incredibly important that we eliminate tailpipe pollution from all cars as soon as possible,” Tonachel told AFP. 

“We need broad acceptance and adoption of EVs across the market. And that’s why it’s encouraging to see automakers starting to make EVs on all types of car segments, including the most popular ones.”

– Customer ‘has spoken’ –

The focus on large vehicles was apparent at last month’s Detroit Auto Show, where Biden test drove the EV Cadillac Lyriq, an SUV made by the GM brand. In previous trips to Detroit, Biden cheered on production of GM’s EV Hummer and the launch of Ford’s F-150 EV.

While GM’s display at the Detroit show included the Bolt, an EV sedan, greater prominence went to electric versions of three larger Chevies: the Silverado pickup, and the Blazer and Equinox SUVs. 

“The customer has spoken. SUVs and trucks are what the customer wants,” Chevrolet Vice President Steve Majoros told AFP at the show. 

NRDC’s Tonachel notes that some sedans still sell at substantial levels in the United States, but that they are made by companies like Japan’s Toyota and South Korea’s Hyundai.

“The different manufacturers are sort of carving out what they see as their specialty,” he said. “The Detroit three automakers, they left the compact car and most of the sedan market years ago.”

Bertrand Rakoto, global automotive practice leader at Ducker in Detroit, a consultancy, said it makes more sense to focus on trucks to fight climate change.

“You’re removing the emissions for the large vehicles that are the most emitting,” he said.

Rakoto, who is originally from France, said the contrast between the United States and Europe reflect different geographic qualities and transportation systems, with space in Europe more precious and public transit more integrated into regular life.

– Energy drain –

A December 2021 International Energy Agency report bemoaned the rise of SUVs, not only in the United States, but in India and Europe.  

Most of the vehicles still run on gasoline, meaning that “if SUVs were an individual country, they would rank sixth in the world for absolute emissions in 2021, emitting over 900 million tons of CO2,” the IEA said.

The analysis said SUV electrification helps, but noted larger vehicles require more critical materials for bigger batteries and consume around 20 percent more energy than a medium-sized car.

For Benjamin Stephan, of Greenpeace in Germany, limiting global warming remains critical, meaning “you sort of have to pull every lever available.”

“Obviously an all-electric pickup truck will have a much better carbon footprint,” he said. “But you could reduce that footprint even more by having no car at all, or a much smaller car.”

Cyclone Sitrang hits Bangladesh, hundreds of thousands of people evacuated

Commuters make their way along a street during a rain shower in Faridpur, Bangladesh on October 24, 2022, ahead of Cyclone Sitrang

Cyclone Sitrang slammed into densely-populated, low-lying Bangladesh late Monday, killing at least five people as authorities fearing heavy rain and storm surge rushed to move hundreds of thousands out of the system’s path.

Sitrang, packing winds of 80 kilometers (50 miles) per hour, made landfall along the Chittagong-Barisal coast around 9:00 pm (1500 GMT), government meteorologist Abul Kalam Mallick told AFP.

The storm was moving swiftly over the country’s southern region and its outer bands were already impacting Dhaka, hundreds of kilometers away from the Bay of Bengal, with trees uprooted and roads flooded in the capital. 

Mallick said some coastal towns had received nearly 294 milimetres (12 inches) of rainfall. 

At least five people had been killed  in the districts of Barguna, Narail, Sirajganj and the island district of Bhola, disaster ministry control room spokesman Nikhil Sarker told AFP.

“The casualties may rise as we are hearing from our officials from some other districts as well,” he said.

Cyclones — the equivalent of hurricanes in the North Atlantic or typhoons in the Northwest Pacific — are a regular and deadly menace on the coast of the northern Indian Ocean where tens of millions of people live.

But scientists say climate change is likely making them more intense and frequent, and Bangladesh is already rated by the United Nations as one of the countries most affected by extreme weather events since the turn of the century.

Most worrying for authorities was the predicted storm surge of up to three metres (10 feet) above normal tide levels, which could inundate areas home to millions of people.

About 33,000 Rohingya refugees from Myanmar, controversially relocated to a storm-prone island in the Bay of Bengal, were advised to remain indoors.

The newly-formed silt island of Bhashan Char, where Bangladesh has been relocating Rohingya refugees to alleviate overcrowding in their refugee camps, was expected to be hit by heavy rains and strong winds.

“The Bhashan Char shelters are protected by a 19-feet-high embankment. Still, we asked people to stay at home,” a senior security officer told AFP from the island.

The government had hoped to evacuate about 2.5 million other people ahead of the storm, the country’s disaster management minister Enamur Rahman told reporters earlier Monday.

“The evacuation has already begun from the morning,” the minister said, adding that more than 7,000 shelters have been readied in an effort to keep casualties to a minimum.

At least 250,000 people had already been evacuated from coastal districts to cyclone shelters by the afternoon, two regional administrators told AFP.

Tens of thousands of volunteers were mobilised for the effort, said a spokesman for the local chapter of the Bangladesh Red Crescent Society.

“We have already evacuated the most vulnerable people, especially those who live in remote islands and river banks and those who live in flimsy houses,” Aminul Ahsan, regional administrator of Barisal, told AFP.

“In some places we have used force to bring people to cyclone shelters. It is for their own safety,” another regional administrator said.

The Red Crescent Society has mobilised tens of thousands of volunteers to help villagers evacuate, spokesman Shahinur Rahman said.

– India evacuations –

In the neighbouring eastern Indian state of West Bengal, several thousand people were also being evacuated as a precaution, with more than 100 relief centres opened, officials said.

“A special squad is making a round-the-clock vigil along the coastline of the state,” West Bengal government minister Arup Biswas said.

“Fishermen have been asked not to venture into the sea. Ferry services have also been suspended,” he said.

In 2020, Cyclone Amphan, only the second “super cyclone” ever recorded over the Bay of Bengal, killed more than 100 people in Bangladesh and India, and affected millions.

Last year, more than a million people were evacuated along India’s east coast before Cyclone Yaas battered the area with winds gusting up to 155 kilometres an hour — equivalent to a Category 2 hurricane.

The 1970 Bhola cyclone, one of the world’s worst natural disasters, killed several hundred thousand people in Bangladesh — then known as East Pakistan — and India.

In recent years, better forecasting and more effective evacuation planning have dramatically reduced the death toll from such storms.
