The road through Cristalina, Brazil is in the middle of the tropics, but the fields on either side look like they are covered in snow — little white puffs of cotton stretching to the horizon.

The alabaster plants interspersed with the corn and soybean fields outside the central-western town are part of a silent revolution in Brazil: facing negative attention over the agribusiness industry’s environmental impact, farmers are increasingly turning to cotton and adopting sustainable techniques to produce it.

After increasing exports 15-fold in the past two decades, Brazil is now the world’s second-biggest cotton supplier, after the United States — and the biggest producer of sustainable cotton.

No less than 84 percent of the cotton grown in the South American agricultural giant is certified by the Better Cotton Initiative (BCI), an international non-profit group to promote sustainable cotton farming.

“Consumers have changed. People don’t want to buy products any more that don’t respect nature and its cycles,” says entomologist Cristina Schetino of the University of Brasilia, who specializes in cotton farming.

The industry is trying to improve the international image of Brazilian farming, tarnished by a history of slave labor, heavy pesticide use and the destruction of the Amazon rainforest for agriculture, a trend that has accelerated under far-right President Jair Bolsonaro — an agribusiness ally.

In 2005, the Brazilian Cotton Producers’ Association (Abrapa) launched a sustainability training program for farmers and introduced protocols on efficiently using water and pesticides and phasing out toxic products in favor of biological fertilizers.

A new tracing program launched with Brazilian clothing brands, meanwhile, lets consumers check how cotton goods were produced.

Last season, cotton farmers in Brazil replaced 34 percent of chemical pesticides with biological ones, Abrapa says.

They have also started using drones to apply pesticides more efficiently.

Switching to sustainable techniques is “a re-education process,” says Abrapa’s executive director, Marcio Portocarreiro.

“At first, farmers tend to think mainly about the impact on their bottom line. But when they get past that phase… they realize that farming sustainably gives them a guaranteed market,” he told AFP.

– Added value –

Located outside Cristalina, around 130 kilometers (80 miles) south of Brasilia, the capital, Fazenda Pamplona is one of Brazil’s biggest proponents of sustainable cotton.

The 27,000-hectare (67,000-acre) operation, run by agribusiness giant SLC Agricola, is like a small city in the middle of the countryside, with a banquet hall, a children’s park, sports fields and housing for employees.

The farm aims to retain workers by creating a home where they will want to stay, says production coordinator Diego Goldschmidt.

He stands in front of two enormous bales of cotton, labeled with QR codes that detail their harvest.

“These are already sold,” he beams.

The farm produced more than 600,000 tonnes last year, 99 percent of it for export.

Sustainable cotton sells for prices up to 10 percent higher than conventional cotton.

“Besides being the right thing to do for society and the environment, it provides added value,” says Goldschmidt.

– Aiming high –

But cotton remains one of the most pesticide-intensive crops, using more than double that of soy per hectare.

The problem is the prevalence of pests such as boll weevils and the absence of organic products to stop them, says Schetino.

“There’s still a lot of dependence on chemical products, which have a negative environmental impact,” says the entomologist, who is researching alternatives.

Brazil cultivates around 1.6 million hectares of cotton a year. It is a key supplier for the global garment industry, exporting to the likes of China, Vietnam, Pakistan and Turkey.

Abrapa has set itself the ambitious goal of surpassing the US to become the world’s biggest cotton supplier in 2030.

“Brazil may not have a good image on sustainable farming yet,” says Goldschmidt.

“But we will soon. There’s a lot of potential.”

A popular Chinese medical information site has been censored by authorities for “violation of relevant laws and regulations”, months after its criticism of a government-backed herbal Covid-19 treatment sent shares in a pharmaceutical giant tumbling.

DXY, which counts tech giant Tencent among its investors and runs a host of health-related services, previously questioned the value of Lianhua Qingwen, a herbal remedy marketed for fever and sore throats, as a Covid-19 treatment.

China approved the concoction — made up of ingredients like honeysuckle and apricot seeds — as a Covid-19 treatment in 2020, and it was distributed to Shanghai residents during the city’s outbreak this year.

DXY’s article, which has now been deleted from its website, was part of a wave of reports that caused shares in Lianhua Qingwen’s producer — one of China’s largest traditional medicine companies — to plunge.

The website has now been banned from posting on at least five of its Weibo social media accounts, with a notice at the top of its official page saying that due to “violation of relevant laws and regulations, this user is currently prohibited from posting”.

DXY’s official WeChat accounts, which typically publish multiple articles a day on medical topics, have not been updated since Monday.

The Weibo notice did not specify which regulations had been violated by DXY, which did not immediately respond to AFP’s request for comment.

– ‘No right to ban them’ –

The Chinese government has increasingly promoted traditional medicine at home and abroad in recent years, often with nationalistic undertones.

DXY’s coverage prompted criticism that it was targeting traditional Chinese medicine (TCM) in order to promote Western pharmaceuticals. 

The decision to freeze DXY’s social media accounts was lauded by some Weibo users, who accused the company of working with “anti-China forces” and peddling false information.

“For this vicious thing eating the anti-Chinese capitalists’ dog food, the best days are in the past,” one Weibo user wrote.

But others lamented the loss of a valued source of misinformation-free medical guidance and said they disagreed with the censorship.

“My mother used to be the kind of person who would make her kids eat chicken gallbladder for fevers,” one wrote, crediting DXY with giving her parent access to modern medical information.

“You have the right to (criticise) DXY on Weibo, but you don’t have the right to ban them,” the user wrote.

The United States and other countries have warned there is no evidence Lianhua Qingwen works to prevent or cure Covid-19, even as it has increasingly been promoted by government authorities in China and Hong Kong.

The US Food and Drug Administration has said it has not approved Lianhua Qingwen and that coronavirus-related claims about it were “not supported by competent and reliable scientific evidence”.

Beijing issued its first white paper on TCM in 2016, laying out plans to build medicine centres and dispatch practitioners to developing countries in Africa and Southeast Asia.

President Xi Jinping has described TCM as a “treasure of Chinese civilisation” and has said that it should be given as much weight as other treatments.

Beijing’s National Health Commission has also dispatched TCM practitioners as part of its medical reinforcement teams sent to fight Covid-19 outbreaks across the country.

Generating power from sunlight bouncing off the ground, working at night, even helping to grow strawberries: solar panel technology is evolving fast as costs plummet for a key segment of the world’s energy transition.

The International Energy Agency says solar will have to scale up significantly this decade to meet the Paris climate target of limiting temperature rises to 1.5 degrees Celsius above pre-industrial levels.

The good news is that costs have fallen dramatically. 

In a report on solutions earlier this year, the Intergovernmental Panel on Climate Change said solar unit costs had dropped 85 percent between 2010 and 2019, while wind fell 55 percent. 

“There’s some claim that it’s the cheapest way humans have ever been able to make electricity at scale,” said Gregory Nemet, a professor at the University of Wisconsin–Madison and a lead author on that report.

Experts hope the high fossil fuel prices and fears over energy security caused by Russia’s invasion of Ukraine will accelerate the uptake of renewables. 

Momentum gathered pace on Sunday with the ambitious US climate bill, which earmarks $370 billion in efforts to cut greenhouse gas emissions by 40 percent by 2030.

An analysis by experts at Princeton University estimates the bill could see five times the rate of solar additions in 2025 as there were in 2020.

Nemet said solar alone could plausibly make up half of the world’s electricity system by mid-century, although he cautioned against looking for “silver bullets”. 

“I think there really is big potential,” he told AFP.

– Rapid changes –

The “photovoltaic effect” — the process by which solar cells convert sunlight to electrical energy — was first discovered in 1839 by the French physicist Edmond Becquerel.

After decades of innovations, silicon-based solar cells started to be developed in the United States in the 1950s, with the world’s first solar-powered satellite launched in 1958.

The IPCC said of all energy technologies, small-scale ones like solar and batteries have so far proved quicker to improve and be adopted than bulkier options like nuclear.

Today, almost all of the panels glimmering on rooftops and spreading across vast fields are made in China using silicon semiconductors. 

But the technology is changing quickly. 

In a recent report, the IEA said these new solar cells have proven to be one-fifth more efficient in converting light to energy than standard modules installed just four or five years ago.

There are also a host of new materials and hybrid cells that experts predict could supercharge efficiency.

These include cheap, efficient and lightweight “thin film” technologies, like those using perovskites that can be printed from inks. 

Experts say they raise the prospect of dramatically expanding where solar energy can be harvested — if they can be made durable enough to withstand a couple of decades of use. 

Recent research has raised hopes that it could be possible.

In one study, published in the journal Science in April, scientists added metal-containing materials to perovskite cells, making them more stable with efficiency near traditional silicon models.

Other research mixes materials for different purposes.

One study in Nature used “tandem” models, with perovskite semiconductors to absorb near-infrared light on the solar spectrum, while an organic carbon-based material absorbed ultraviolet and visible parts of the light.

And what happens after sunset? 

Researchers from Stanford said this year they had produced a solar cell that could harvest energy overnight, using heat leaking from Earth back into space.

“I think that there’s a lot of creativity in this industry,” said Ron Schoff, who heads the Electric Power Research Institute’s Renewable Energy and Fleet Enabling Technologies research.

– Location, location –

Generating more energy from each panel will become increasingly crucial as solar power is rolled out at greater scale, raising concerns about land use and harm to ecosystems.

Schoff said one efficiency-boosting design that is becoming more popular for large-scale projects is “bifacial” solar. 

These double-sided units absorb energy not just directly from the sun’s rays, but also from light reflected off the ground beneath. 

Other solutions involve using the same space for multiple purposes — like semi-transparent solar panels used as a protective roof for strawberry plants or other crops.

India pioneered the use of solar panels over canals a decade ago, reducing evaporation as they generate power.

Scientists in California have said that if the drought-prone US state shaded its canals, it could save around 63 billion gallons.

Construction on a pilot project is due to begin this year.

– All shapes, sizes –

Experts say solar will be among a mix of energy options, with different technologies more suitable for different places.

Schoff said ultimately those energy grids with more than 25 percent solar and wind need ways to store energy — with batteries or large-scale facilities using things like pumped water or compressed air.

Consumers can also play their part, said Nemet, by shifting more of their energy use to daytime periods, or even hosting their own solar networks in an Airbnb-style approach.

He said the modular nature of solar means it can be rolled out in developing countries with sparse access to traditional grids.

“You could have solar on something as small as a watch and something as big as the biggest power plants in the world,” he said.

“I think that’s what’s making people excited about it.”

Singapore on Thursday narrowed its economic growth forecast this year after the economy contracted in the second quarter compared to the previous three months due to rising inflation and tighter monetary policies, the government said.

Moves by central banks worldwide to tighten borrowing costs in order to deal with rocketing prices have weighed down on global demand for Singapore’s exports, with the government painting a grim picture for the rest of the year.

Economists often see the performance of the city state’s open, trade-driven economy as a barometer for global trading activity.

Singapore’s economy is now projected to expand by 3.0 to 4.0 percent this year, trimmed from a 3.0 to 5.0 forecast earlier, the trade ministry said in a statement.

The economy grew by 4.4 per cent year-on-year in the second quarter to June, faster than the 3.8 per cent growth recorded in the previous quarter, it said.

But compared to the previous three months, the economy contracted by 0.2 per cent, reversing the 0.8 percent expansion in the first quarter.

“Since May, the global economic environment has deteriorated further,” the ministry said.

“Stronger than expected inflationary pressures and the more aggressive tightening of monetary policy in response are expected to weigh on growth in major advanced economies such as the US and Eurozone.”

China, a key market for global exports, “continues to grapple with a deepening property market downturn and recurring domestic Covid-19 outbreaks”, it said.

“Notwithstanding recent signs of a slight easing in global supply disruptions, the disruptions are likely to persist for the rest of the year as underlying factors such as the Russia-Ukraine conflict and China’s zero-Covid policy remain,” it added.

Growth in the United States is expected to slow further in the second half of the year, and “the persistent disruption in natural gas supplies from Russia could also trigger a sharp slowdown in the Eurozone economy”, it warned.

Selena Ling, chief economist at OCBC Bank, said the strong recovery in the aviation and tourism sectors after Singapore lifted coronavirus restrictions should help cushion the effects of slowing global demand.

Facebook sparked outrage by complying with US police probing an abortion case, boosting simmering fears the platform will be a tool for clamping down on the procedure.

Criticism built after media reports revealed the social networking giant had turned over messages key to a mother being criminally charged with an abortion for her daughter.

Advocates had warned of exactly this kind of thing after America’s top court revoked the national right to abortion in late June, as big tech companies hold a trove of data on users locations and behavior.

Jessica Burgess, 41, was accused of helping her 17-year-old daughter to terminate a pregnancy in the midwestern US state of Nebraska.

She faces five charges — including one under a 2010 law which only allows abortion up to 20 weeks after fertilization.

The daughter faces three charges, including one of concealing or abandoning a corpse.

Yet Facebook owner Meta defended itself Tuesday by noting the Nebraska court order “didn’t mention abortion at all”, and came before the Supreme Court’s highly divisive decision in June to overturn Roe v Wade, the case which conferred right to abortion in the United States.

“That sentence would seem to imply that *if* the search warrants mentioned abortion, there would be a different result. But of course that’s not true,” tweeted Logan Koepke, who researches on how technology impacts issues like criminal justice.

When queried about handing over the data, the Silicon Valley giant pointed AFP to its policy of complying with government requests when “the law requires us to do so.”

Nebraska’s restrictions were adopted years before Roe was overturned. Some 16 states have outright bans or limits in the early weeks of pregnancy in their jurisdictions.

– ‘Can’t release encrypted chats’ –

For tech world watchers, the Nebraska case surely won’t be the last. 

“This is going to keep happening to companies that have vast amounts of data about people across the country and around the world,” said Alexandra Givens, CEO of the non-profit Center for Democracy & Technology.

She went on to note that if companies receive a duly-issued legal request, under a valid law, there are strong incentives for them to want to comply with that request. 

“The companies at a minimum have to make sure that they’re insisting on a full legal process, that warrants are specific and not a fishing expedition, searches are very narrowly construed and that they notify users so that users can try to push back,” Givens added.

Meta did not provide AFP the Nebraska court’s order. The police filing asked the judge to order the company not to tell Burgess’s daughter about the search warrant for her Facebook messages.

“I have reason to believe that notifying the subscriber or customer of the issuance of this search warrant may result in the destruction of or tampering with evidence,” police detective Ben McBride wrote.

He told the court he began investigating “concerns” in late April that Burgess’s daughter had given birth prematurely to a “stillborn child”, which they allegedly buried together.

Advocates noted that apart from not using Meta’s products, one sure way to keep users’ communications out of government hands would be for them to be automatically encrypted.

Meta-owned WhatsApp has end-to-end encryption, which means the company does not have access to the information, but that level of privacy protection is not the default setting on Facebook messenger.

“The company has never said it would not comply with a request from law enforcement in a situation related to abortions,” said Caitlin Seeley George, a campaign director at advocacy group Fight for the Future. 

“If users could rely on encrypted messaging, Meta wouldn’t even be in a position where they could share conversations,” she added.

The Disney+ streaming service saw its number of paying subscribers leap beyond expectations in the last quarter, as rival Netflix’s client count ebbed, results showed Wednesday.

The number of people subscribing to Disney+ topped 152 million, up some 31 percent from the same period a year earlier, the entertainment giant said in an earnings report.

Disney’s bottom line was also boosted by rising revenue from its theme parks, which showed signs of recovering from stifled attendance during the pandemic.

Better-that-expected earnings reported by Disney came as many of the tech titans that flourished during the pandemic curb costs in the face of inflation and people get back to living life in the real world instead of online.

Disney shares were up more than 6 percent in after-market trades that followed release of the earnings figures.

“We had an excellent quarter, with our world-class creative and business teams powering outstanding performance at our domestic theme parks, big increases in live-sports viewership, and significant subscriber growth at our streaming services,” said Disney chief executive Bob Chapek.

The 14.4 million Disney+ subscribers added in the recently ended quarter raised the overall number of subscriptions to its streaming services, which include Hulu and ESPN+, to 221 million, Chapek added.

The overall number of subscribers to Disney streaming services topped those of Netflix for the first time.

“Investors will breathe a sigh of relief from Disney’s robust fiscal (quarterly) earnings,” said Insider Intelligence principal analyst Paul Verna.

“The streaming figures will be seen as an indicator of the health of the market, especially after lackluster subscriber figures from Netflix and Comcast.”

Disney also announced that an ad-subsidized version of its streaming television subscription service will be offered in the United States starting December 8 at a monthly price $3 less than the ad-free offering.

– K-pop and superheroes –

Taking a page from Netflix’s playbook, Disney has been investing in shows created in places outside the United States.

The company plans to “step up” investments in such local original content, Chapek said, pointing out a film concert and docu-series focused on South Korean music sensation BTS.

He expressed confidence in Disney theater films in the works, including an eagerly anticipated “Black Panther: Wakanda Forever” addition to its Marvel superhero line-up.

A trailer for the Black Panther film logged more than 170 million views in the 24 hours after its release, Chapek said.

“Disney still faces economic uncertainty and intense competition, but performance should at least temporarily put to rest some of Wall Street’s gloomier perceptions about the company, and more broadly about the entertainment industry,” said Paul Verna, an analyst at Insider Intelligence.

Rival Netflix has reported losing subscribers for two quarters in a row, as the streaming giant battles fierce competition and viewer belt tightening, though the firm assured investors of better days ahead.

The loss of 970,000 paying customers in the most recent quarter was less than expected, leaving Netflix with just shy of 221 million subscribers.

“Our challenge and opportunity is to accelerate our revenue and membership growth… and to better monetize our big audience,” the firm said in its earnings report.

After years of amassing subscribers, Netflix lost 200,000 customers worldwide in the first quarter compared to the end of 2021. 

Netflix said in its earnings report that it had expected to gain a million paid subscribers in the current quarter.

Netflix executives have made it clear the company will get tougher on sharing logins and passwords, which allow many to access the platform’s content without paying. 

In an effort to draw new subscribers, Netflix said it will work with Microsoft to launch a cheaper subscription plan that includes advertisements.

The ad-supported offering will be in addition to the three account options already available, with the cheapest plan coming in at $10 per month in the United States.
