About one in eight essential medicines in low- and middle-income countries may be fake or contain dangerous mixes of ingredients that put patients’ lives at risk, a research review suggests.

Researchers examined data from more 350 previous studies that tested more 400,000 drug samples in low- and middle-income countries. Overall, roughly 14 percent of medicines were counterfeit, expired or otherwise low quality and unlikely to be as safe or effective as patients might expect.

“Low-quality medicines can have no or little active pharmaceutical ingredient [and] can prolong illness, lead to treatment failure and contribute to drug resistance,” said lead study author Sachiko Ozawa of the University of North Carolina at Chapel Hill.

“Or it may have too much active ingredient and cause a drug overdose,” Ozawa said by email. “If it is contaminated or has other active ingredients, then the medication could cause poisoning, adverse drug interactions or avertable deaths.”

Much of the research to date on counterfeit or otherwise unsafe medicines has focused on Africa, and about half of the studies in the current analysis were done there.

Almost one in five medications tested in Africa were fake or otherwise potentially unsafe, researchers report in JAMA Network Open.

Another third of the studies were done in Asia, where about 14 percent of medicines tested were found to be counterfeit or otherwise unsafe.

Antibiotics and antimalarials were the most tested drugs in the analysis. Overall, about 19 percent of antimalarials and 12 percent of antibiotics were falsified or otherwise unsafe.

While fake or improperly made medicines undoubtedly harm patients, the current analysis couldn’t tell how many people suffered serious side effects or died as a result of falsified drugs.

Researchers did try to assess the economic impact of counterfeit or improperly made medicines and found the annual cost might run anywhere from $10 billion to $200 billion.

While the study didn’t examine high-income countries, drug quality concerns are by no means limited to less affluent nations, Ozawa said.

“Even in high-income countries, purchasing cheaper medicines from illegitimate sources online could result in obtaining substandard or falsified medicines,” Ozawa said. “Verify the source before you buy medications, and make policymakers aware of the problem so they can work to improve the global supply chain of medicines.”

The study wasn’t a controlled experiment designed to prove whether or how counterfeit or poorly made medicines directly harm patients, however. And economic impact was difficult to assess from smaller studies that often didn’t include detailed methodology for calculating the financial toll.

The report “provides important validation of what is largely already known,” Tim Mackey of the Global Health Policy Institute in La Jolla, California, writes in an accompanying editorial.

“It is important to note that although the study is comprehensive, its narrow scope means it only provides a snapshot of the entire problem, as it is limited to studies conducted in low- and middle-income countries and to those

medicines classified as essential by the World Health Organization.”

The number of sexually transmitted diseases in the United States is hitting record highs, according to latest data from the Centers for Disease Control and Prevention (CDC).

Nearly 2.3 million cases of chlamydia, gonorrhea and syphilis were diagnosed in 2017, says the CDC. This is the fourth year of increases in STDs and the figures broke 2016’s record by more than 200,000 cases.  

Chlamydia remained the most common condition reported to the CDC. More than 1.7 million cases were diagnosed in 2017, with 45 percent among 15- to 24-year-old females. 

Chlamydia, gonorrhea, and syphilis often go undiagnosed and untreated, leading to conditions including infertility, ectopic pregnancy, stillbirth in infants, and increased HIV risk. 

“We are sliding backward,” said Dr. Jonathan Mermin, director of the CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD and TB Prevention, in a news release. “It is evident the systems that identify, treat and ultimately prevent STDs are strained to [a] near-breaking point.

“Diagnosed cases of gonorrhea increased 67 percent from 333,004 to 555,608 cases, and nearly doubled among men, from 169,130 cases to 322,169 in preliminary data for 2017. Diagnosed cases among women increased for the third year in a row from 197,499 to 232,587.

Syphilis diagnoses increased 76 percent, from 17,375 to 30,644 cases. Gay, bisexual and other men who have sex with men made up almost 70 percent of primary and secondary syphilis cases where the gender of the sex partner is known in 2017. Primary and secondary syphilis are the most infectious stages of the disease.

Researchers say the increases in STDs can be attributed to socioeconomic factors like poverty, stigma, discrimination, and drug use.

While most of the diseases are curable with antibiotics, gonorrhea continues to be resistant to nearly every class of antibiotics used to treat it, with the exception of ceftriaxone. 

In 2015, the drug azithromycin was added to treatment for gonorrhea to help delay resistance to ceftriaxone. New CDC findings show that emerging resistance to azithromycin is on the rise in laboratory testing.

“We expect gonorrhea will eventually wear down our last highly effective antibiotic, and additional treatment options are urgently needed,” said Gail Bolan, M.D., director of the CDC’s Division of STD Prevention in a press release. “We can’t let our defenses down — we must continue reinforcing efforts to rapidly detect and prevent resistance as long as possible.”

Algerian health authorities claim the situation is under control after a cholera epidemic in at least four provinces caused more than 60 confirmed cases of the disease, with several deaths reported.

Residents in a village of Tipaza province are drinking water from a spring government officials claim is infected with the cholera virus. But residents counter the spring is safe to drink from and that the government analysis is mistaken.

Cholera outbreaks have been confirmed in Tipaza, Blida, Algiers, and Bouira provinces.   More than 130 people have been hospitalized with suspected cases of cholera this month and more than 60 cases were confirmed.  At least three people have died, according to Algerian media.

Algeria’s health minister, Mokhtar Hazblawi, recently said health officials have been doing their best to keep on top of the situation.

He says since the disease surfaced, the health ministry has devised a strategy to control it and stop it from spreading.

Issam Eddin Bouyoucef of the El Hadi Flici Hospital Center, which treats infectious diseases in Algiers, told Al Hurra TV hundreds of people have come to the hospital fearing they were suffering from cholera.  

He said patients must be quarantined and the disease isolated. He stressed his hospital has set up a specialized isolated wing to treat patients while they recover, once the disease has been confirmed.

Bouyoucef said many people have been panicking, mistaking stomach ailments for cholera. Local media report consumers are buying up large quantities of mineral water.

An elderly resident of capital Algiers told Al Hurra TV he was afraid of the potentially deadly disease and thinks that a large number of people who live in his area have been sickened.

Physician Mohammed Gamary complained to a local TV station the media uncovered the cholera epidemic before the government did. He said doctors in Khazrouna, where the disease was first detected, should have sounded the alarm when they noticed the unusual number diarrhea cases.

Pharmacies in Algiers have been selling large quantities of salts to treat diarrhea, while many people have been avoiding fruit and vegetables, which they fear may be contaminated with the cholera virus.

The World Health Organization says Africans are living longer and healthier lives.  But the WHO warns that that millions on the continent still face the challenge of chronic diseases.  

News of the uptick came in Dakar this week where WHO representatives met with officials from 47 African countries.

Healthy life expectancy on the continent rose from 44.4 years at the turn of the century to 53.8 years in 2015. Overall life expectancy climbed from 50.8 years to 61.2.

 

Matshidiso Moeti, the WHO’s regional director for Africa, said that two factors were mostly responsible for the change.

 

“What produced this result is a huge increase in access to treatment [of] HIV-AIDS, and in the better prevention and management of malaria,” Moeti said.

But the WHO says the type of disease that most commonly affects Africans is also changing.  

While the number of deaths from diarrheal disease, respiratory infections, and HIV is falling, chronic conditions – such as cancer and heart disease – are claiming more lives.

Death rates from non-communicable diseases have remained steady since 2000 while the other top ten causes of mortality in Africa have fallen by 40 percent.

The WHO says health services in Africa have been slow to adapt to the new health challenges.

Humphrey Karamagi, sustainable development goal coordinator for the WHO, says the health needs of African youth are too often overlooked.

“The kind of health challenges that adolescents face are quite different from what we have been used to responding to – drug use, adolescent obesity and so on.”

Many African health officials and experts point to a lack of funding, but Stanley Okolo, head of the West African Health Organization, says that is overly simplistic.

“There is health, which is an issue in terms of investment and health funding. But there is also an issue in terms of health systems and how you can deliver better value for the money you have. And both have to be tackled simultaneously,” Okolo said.

African nations spend an average 40 percent of their health budgets on medical products, while barely a fifth goes to medical staff and infrastructure.

Health officials from Kenya, Nigeria and Cabo Verde say they are responding to the rise in non-communicable diseases by focusing on prevention and promoting healthy lifestyles.

Chinese authorities should not arbitrarily shut down firms that meet emission standards during environmental cleanup campaigns, Vice Premier Han Zheng said on Wednesday.

Beijing has made reducing pollution one of its highest national priorities, but the drive has been criticized as poorly planned at the local level, with across-the-board closures of industrial plants in some regions ensnaring even compliant companies.

Xinhua news agency quoted Han as saying that measures in the battle against pollution should be realistic and sustainable, though environmental protection policies should be strictly enforced to deter companies that violate the rules.

He was speaking at a meeting on a plan to tackle pollution in and around the Beijing-Tianjin-Hebei region during the winter, when smog often blankets northern China.

The Ministry of Ecology and Environment said in May that China would end a “one size fits all” approach to fighting pollution as it tries to devise more nuanced policies that match local conditions and minimize economic disruption.

A plan to switch millions of households and thousands of businesses from coal to natural gas in north China last winter backfired as severe gas shortages hit the region. “Steadily promote clean winter heating in North China, and ensure people are safe and warm,” Han said.

Iraqi health officials say that a health crisis stemming from water pollution and a shortage of clean drinking water has worsened in recent days, as hospitals in the southern port city of Basra treat more than 1,000 cases of intestinal infections on a daily basis. The problem was exacerbated several months ago when Turkey cut back on water distributed to the Tigris and Euphrates Rivers.

 

A crowd of young men took to the streets on in the southern port city of Basra Tuesday, demanding the central government and Prime Minister Haidar al-Abadi increase the quantity of clean drinking water allotted to their province. Abadi vowed to increase spending on infrastructure for the province during a visit to Basra in July.

A young man, whose friend was killed during a rally several weeks ago, broke down and sobbed over the protesters’ inability to force Iraqi leaders to improve the condition of public services in Basra, especially the region’s worn-out water infrastructure and insufficient quantities of drinking water allotted by the central government.

Some health officials in Basra warn that a cholera outbreak is possible due to water pollution and water-borne parasites that have made thousands of people sick in recent days. The director general of the Basra Health department, Riad Abdul Amir, told Al Hurra TV the situation continues to worsen.

He says more than 17,500 cases of intestinal ailments, resulting from contaminated drinking water, have been treated by Basra hospitals during the past two weeks, alone.

Abdul Amir says the problem stems from insufficient fresh water supplies coming into the city via canals and water pipes from the north.

“Salty water [which has infiltrated the water network],” he asserts, “is known to reduce the efficacy of chlorine used to treat and kill bacteria in drinking water,” he said.

Safaa Kazem, a docotor who has been treating dozens of cases of intestinal problems and diarrhea in Basra’s Sadr Teaching Hospital each day, says water from the city’s supply is not safe to drink.

She says the degree of water sterilization is minimal and that Basra’s water is very salty and has an extremely high level of microbes in it, along with a high degree of chemical pollution.

Basra Governor Assad al Edani told Al Hurra TV that his province has been suffering from numerous infrastructure problems for a long time.

He says the water network in Basra hasn’t been updated in at least 30 years and the old pipes often break, mixing drinking water with sewage.

Edani says “not enough fresh water is arriving via the region’s only canal from Thi Qar province to the north.” He thinks a “strong current of fresh water will flush out salty water seeping into the water network from the sea.”

Edani adds that the population of Basra has “more than doubled since the water network was last updated in the early 1990s.”

Iraq’s individual provinces have been fighting for water, amid a general shortage, since Turkey in early June severely curtailed the number of cubic meters of water it funnels into both the Tigris and Euphrates rivers.

Amanda Greene lives with pain.

“If I don’t have nerve pain, I might have joint pain. If I’m not having joint pain, I might have headaches,” Greene said.

The unrelenting pain is a symptom of lupus, an autoimmune disease in which a patient’s immune system attacks the body. Greene has tried acupuncture, massage and opioids, but realized she was allergic to the addictive pain medicine.

The newest therapy that excites her: virtual reality. Greene participated in a test through the company “appliedVR” to see if and how virtual reality could help patients. Greene’s virtual experience helped her to relax and trained her to breathe in a specific way. She saw a tree, crystals, water and her breath as she was guided to inhale and exhale.

“It worked. It works for me,” Greene said. “It’s the quality of life, it is the range of motion, it is like, forget about quality of life, it is the life.” 

VR in hospitals and clinics

Brennan Spiegel is a gastroenterologist who has used VR for his patients. He said abdominal pain and gastrointestinal discomfort, in some cases, are related to a patient’s mental state.

“Something like virtual reality actually can intercede in the brain-gut axis and sort of rewire the neurocircuitry in a way that helps to reduce abdominal pain,” said Spiegel, who is also director of Health Services Research at Cedars-Sinai and heads its virtual reality program.

More than 2,500 patients have been treated with virtual reality at Cedars-Sinai, a hospital with the largest documented therapeutic VR program in the world, according to Spiegel.

“Virtual reality can reduce pain, can reduce blood pressure, can improve quality of life, reduce anxiety and now, we’re looking to see can it do really important things like reduce the need for opioids.”

Spiegel said more than 100 hospitals across the United States are using VR as a form of therapy for patients to help manage symptoms such as pain and anxiety. He said an increasing number of countries worldwide are taking an interest, and doctors are starting to develop international guidelines on how to apply and validate the technology in health care.

Spiegel is now taking virtual reality outside the hospital to partner clinics such as Attune Health in Los Angeles, where many of the patients suffer from autoimmune or inflammatory diseases that cause symptoms such as joint pain.

A rheumatologist and founder of Attune Health, Swamy Venuturupalli is conducting a study on how VR can reduce the pain levels of patients in his clinic. Virtual experiences include swimming with dolphins and meditation exercises before a campfire. Venuturupalli said VR is not just a distraction for patients experiencing pain; it can also train them in deep breathing exercises and biofeedback.

“It allows you to connect with that part of your brain that you’re normally not in contact with — the part of the brain that controls respiration, the part of the brain that controls your heart rate and the emotional part of your brain,” Venuturupalli said.

Doctors are also looking into the potential side effects of VR, such as whether it could be addictive.

“It’s probably unlikely and, in fact, we have not seen abuse amongst our patients who are using it for therapeutic purposes rather than for gaming or entertainment,” Spiegel said.

The most common side effect for some patients, according to Spiegel, is “simulator sickness,” the feeling of dizziness and nausea when the patient is wearing a VR headset. He said less than 10 percent of patients experience this, but the symptoms quickly disappear when the headset comes off.

VR pharmacy and clinics

The company appliedVR uses immersive technology to help people manage pain and anxiety. It also is developing content and working with people in entertainment and academia to find VR experiences appropriate for patients. The vision is to have a VR pharmacy. 

“You need a wide variety of content because you have a wide variety of people in health care. From infancy to geriatrics and with every personality type,” said Josh Sackman, president and co-founder of appliedVR.

Swimming with dolphins may relax one patient, yet terrify another. Greene said watching a fashion show in virtual reality helps her escape her pain.

The medical world’s reaction to using VR in the clinical setting has changed in the past three years, said Sackman. In 2015, he experienced skepticism among doctors who wondered why television or a tablet couldn’t be used to distract patients. Sackman said that unlike a screen, VR blocks out the sights and sounds of a hospital or clinic as soon as the patient puts on the VR headset.

“In a matter of moments, you see a patient who is in agony, in terrible pain, stressed, having panic and all of a sudden, their body relaxes, a smile comes on their face and you see a physical transformation,” Sackman said.

Spiegel would like to create outpatient VR clinics. He said the aim is not to have patients stay in VR forever.

“The idea is to learn while you’re in virtual reality, that you do have governance over your body, that the mind matters and that you can learn these skills that are then reproduceable and could be called upon when you need them in the real world,” Spiegel said.

U.S. Senator John McCain’s death from glioblastoma on Saturday brought new attention to the most deadly type of brain cancer. 

The National Brain Tumor Society says 80 percent of brain tumors are benign, but a glioblastoma tumor grows rapidly, and it returns after treatment. It usually affects adults, especially men over age 50, but women and even children can develop this type of cancer. 

Glioblastoma begins in glial cells that surround and support nerve cells. Because glioblastoma spreads so quickly, the sooner the cancer is diagnosed, the more treatment options a patient has. 

Symptoms can include headaches, seizures, memory loss, changes in personality, changes in vision, and difficulty speaking or understanding conversations. The tumor can also affect coordination.

Glioblastoma is generally considered incurable because it is difficult to remove all of the cancer during surgery, which is why it can grow back. Surgery is usually the first treatment, followed by radiation and chemotherapy. McCain’s treatment included these three options.

Drugs used to treat patients with this type of cancer have lengthened patients’ lives over the past two decades. The National Cancer Institute reports that in the mid-1990s, the average survival rate was eight to 10 months. With new drugs patients now live between 15 and 18 months on average. McCain’s tumor was diagnosed in July 2017. He died little more than a year later.

The National Cancer Institute says survival has also improved slightly. In the mid-1990s, essentially no one with glioblastoma survived five years after diagnosis, now 15 percent of patients do, a very small proportion compared with survival rates for most other types of cancer.

Researchers are looking for new ways to treat glioblastoma. Those at Duke University in Durham, North Carolina, are using a modified polio vaccine with promising results. In the first part of a clinical trial, 21 percent of the patients survived for three years after being treated.

At Texas A&M University in College Station, researchers are looking to see whether they can disrupt the body’s production of a protein associated with tumor growth. 

Other research involves seeing whether the body’s own immune system could fight off the cancer cells.

The National Brain Tumor Society issued a statement on McCain’s death. It said the society was “profoundly saddened” and called for a national effort to combat the disease.

When farmer Julimar Pansera purchased land in Brazil’s interior seven years ago, it was blanketed in tiers of fruit trees, twisted shrubs and the occasional palm standing tall in a thicket of undergrowth.

He mowed down most of that vegetation, set it ablaze and started planting soybeans. Over the past decade, he and others in the region have deforested an area larger than South Korea.

Permissive land-use policies and cheap farm acreage here have helped catapult Brazil into an agricultural superpower, the world’s largest exporter of soy, beef and chicken and a major producer of pork and corn. This area has also lured farmers and ranchers away from the Amazon jungle, whose decline has spurred a global outcry to protect it.

The tradeoff, environmentalists say, is that while Brazil has slowed destruction of the renowned rainforest from its worst levels, it has put another vital ecological zone at risk: a vast tropical savanna that is home to 5 percent of species on the planet.

Known as the Cerrado, this habitat lost more than 105,000 square kilometers (40,541 square miles) of native cover since 2008, according to government figures. That’s 50 percent more than the deforestation seen during the same period in the Amazon, a biome more than three times larger. Accounting for relative size, the Cerrado is disappearing nearly four times faster than the rainforest.

The largest savanna in South America, the Cerrado is a vital storehouse for carbon dioxide, the greenhouse gas whose rising emissions from fossil fuels and deforestation are warming the world’s atmosphere. Brazilian officials have cited protection of native vegetation as critical to meeting its obligations under the Paris Agreement on climate change. But scientists warn the biome has reached a tipping point that could hamper Brazil’s efforts and worsen global warming.

By focusing on one problem, Brazil essentially created another, said Ane Alencar, science director of the non-profit Amazon Environmental Research Institute, known as IPAM.

“There’s a high risk for the climate associated with this expansion,” Alencar said. “Limiting and calling attention to deforestation in the Amazon, in a way it forced the agribusiness industry to expand in the Cerrado.”

The toll can already be seen in the region’s water resources. Streams and springs are filling with silt and drying up as vegetation around them vanishes. That in turn is weakening the headwaters of vital rivers flowing to the rest of the country, scientists say. The imperiled waterways include the Sao Francisco, Brazil’s longest river outside the Amazon, where water levels are hitting never-before-seen lows in the dry season.

“The removal of vegetation can lead a body of water to extinction,” said Liliana Pena Naval, an environmental engineering professor at the Federal University of Tocantins.

Wildlife, too, is under threat, including rare hyacinth macaws, maned wolves and jaguars that call the shrinking savanna home. So are thousands of plants, fish, insects and other creatures found nowhere else on earth, many of which are only beginning to be studied.

“I compare it to the burning of the ancient Library of Alexandria,” said Mercedes Bustamante, an ecologist at the University of Brasilia. “You lose the accumulated evolutionary record of thousands of years that never can be recovered.”

Farmers see the Cerrado’s development as critical to global food security and their nation’s prosperity. Brazil’s agriculture sector grew a sizzling 13 percent in 2017, while the overall economy barely budged. The nation’s ability to keep producing new farmland cheaply has given it an edge over rivals and cemented its status as a vital supplier to the world’s tables.

“Imagine, if not for Brazil’s production, how much more hunger would there be,” farmer Pansera said.

The Green Revolution

Roughly the size of Mexico, straddling Brazil’s mid-section from its far western borders with Paraguay and stretching northeast toward the Atlantic coast, the Cerrado has seen about half of its native forests and grasslands converted to farms, pastures and urban areas over the past 50 years.

Deforestation in the region has slowed from the early 2000s, when Brazil’s soy boom was gaining steam. Still, farmers continue to plow under vast stretches of the biome, propelled largely by Chinese demand for Brazilian meat and grain. The Asian nation is Brazil’s No. 1 buyer of soybeans to fatten its own hogs and chickens. China is also a major purchaser of Brazilian pork, beef and poultry to satisfy the tastes of its increasingly affluent consumers.

Rising trade tensions between China and the United States have only deepened that connection. Brazil’s soybean exports by value to China are up 18 percent through the first seven months of the year as Chinese buyers have canceled tens of millions of dollars’ worth of contracts with U.S. suppliers.

The trend bodes well for producers in the Cerrado’s frontier region known as Matopiba, shorthand for the northeastern Brazilian states of Maranhao, Tocantins, Piaui and Bahia. Land here is cheap. Virgin plots near Pansera in the state of Tocantins can be had for $248 an acre on average, according to agribusiness consultancy Informa Economics IEG FNP. That compares to an average of $3,080 per acre for already cleared farmland in the United States. Soy planting in Matopiba has more than doubled over the past decade.

Pansera, 50, is part of a wave of industrious transplants from southern Brazil who are remaking the region. His formal education stopped at middle school, but he found land enough in the Cerrado to match his big ambitions. He now presides over nearly 19 square miles (49 square kilometers) of manicured soy fields and has about 20 full-time workers on his payroll.

Pansera’s soybeans will bring in an estimated profit of nearly 5 million reais ($1.23 million) this year, most of which he plans to invest back into the farm.

Government policies have intentionally driven industrial-scale farming here. Short on farmland to feed its growing population, Brazil in the 1970s looked to its vast savanna, a region early explorers had dubbed “cerrado,” or “closed,” because of its tangled woodlands.

State agriculture scientists developed fertilizers and additives to fix the acidic, nutrient-poor earth and created soybean strains that could thrive in the tropics. Arable land exploded. Within a decade, Brazil transformed itself from a food importer to a net exporter. By the 1990s it was moving global commodities markets.

“Agriculture in the Cerrado is what took Brazil to the next level,” Agriculture Minister Blairo Maggi told Reuters. Known as Brazil’s “Soy King,” Maggi is a billionaire whose family runs one of the largest private soybean operations in the world, much of it in the Cerrado.

Maggi said growers are respectful of legally allowed limits on deforestation. Their “rational” occupation of the Cerrado has helped Brazil’s economy, he said.

Farmers have emerged as a powerful political force bent on keeping Brazil’s countryside open for business. Lawmakers in the country’s largely rural, pro-agriculture voting bloc, who comprise more than 40 percent of the nation’s congress, have led a rollback of environmental laws in recent years.

Those efforts include a 2012 loosening of Brazil’s landmark Forest Code that sets requirements for preserving native vegetation. The change reduced potential penalties for farmers, ranchers and loggers charged with past illegal deforestation, and made it easier for landowners to clear more of their holdings. Annual deforestation in the Amazon last year was up 52 percent from a record low in 2012.

Still, environmental protections there remain the most robust in Brazil. Rainforest farmers are required by law to preserve 80 percent of native vegetation on their plots.

And global grain traders in 2006 voluntarily agreed to stop purchasing any soy harvested from newly deforested Amazon jungle areas. As part of its obligations under the Paris Agreement, the government pledged to eliminate illegal Amazon deforestation by 2030.

Brazil has made no similar push to preserve the Cerrado, which has long been viewed as a resource to be developed.

Cerrado farmers are required to preserve as little as 20 percent of the natural cover, and up to 35 percent in areas neighboring the Amazon. Those who don’t maximize use of their tracts risk having their land declared idle and subject to redistribution under a 1980 federal land-reform initiative aimed at assisting rural, low-income people, said Elvison Nunes Ramos, sustainability coordinator with the Ministry of Agriculture.

“The message being sent to the farmer is that he should not preserve, he should deforest,” Nunes Ramos said of the policy.

A spokesman for Incra, the government agency that verifies the use of the rural land, said its job is to ensure “the fulfillment of the social function of the property.”

Water, wildlife under threat

Environmentalists say the Cerrado’s wooded grasslands have failed to capture the public’s attention the way the Amazon’s lush jungles have.

People view the Cerrado “just as bushes, twisted vegetation and shrubs,” lamented Alencar, the science director at IPAM.

What many don’t see, she said, is the connection between the soybean-fed meat on their plates and the steady decline of one of the world’s great carbon sinks, a bulwark against global warming.

Plants here send roots deep into the earth to survive seasonal drought and fires, creating a vast underground network that some have likened to an upside-down forest. Destruction of surface vegetation, and the resulting die-off of the life below, released 248 million tons of greenhouse gas into the atmosphere in 2016, according to estimates by the Climate Observatory, a Brazilian conservation group. That’s roughly two-and-a-half times the annual tailpipe emissions from all cars in Brazil.

Watersheds are hurting, too.

In Palmeirante, a rural municipality in the state of Tocantins, subsistence farmer Ronivon Matias de Andrade blames expanding mega-farms for damaging a community water source.

Dressed in faded shorts and flip flops, he showed a visitor the remains of what until recently had been a shady woodland: uprooted trees and freshly exposed earth pocked with heavy-equipment tracks.

Stripped of its vegetation, sandy topsoil is now filling a nearby creek and an adjoining freshwater pool where he and other rural families draw drinking water. He scooped up a murky handful in disgust.

“How many are being finished off in this manner in this state?” 43-year-old Andrade said.

Environmentalists say vanishing creeks like those in Palmeirante are threatening the nation’s water supply. Seemingly insignificant sources — tiny brooks, nameless rivulets — are vital building blocks supplying water to tributary streams that in turn feed some of Brazil’s largest rivers.

Of a dozen major water systems in Brazil, eight are born in the Cerrado. They include the Sao Francisco, the country’s fourth-largest river, which was once famed for its paddle-wheeled riverboats known as gaiolas. Environmentalists say man-made diversions, including agriculture and hydroelectric dams, have helped alter water levels to a degree that long stretches of the river are now unnavigable during the dry season.

Loss of native ground cover is also driving microclimate change in the region, they say. Reduced vegetation leads to higher ground temperatures and lower humidity, a recipe for less rainfall. A study conducted at the University of Brasilia links deforestation to an 8.4 percent drop in precipitation from 1977 to 2010 in the Cerrado.

Cerrado wildlife is under pressure as habitat shrinks. More than 300 species that dwell here are considered threatened with extinction, according to the government. Among them are 44 rare types of “annual fish” unique to the Cerrado whose short lives begin with spring rains and end with the summer heat. Scientists suspect that increasing dry spells could be interrupting their delicate reproduction cycles.

Other creatures, including rheas — giant ostrich-like birds — will soon join the endangered species list if nothing is done to reverse the slide, says Ricardo Machado, a zoology professor at the University of Brasilia. He said the birds’ numbers have plummeted due to loss of native ground cover critical to breeding and nesting.

Machado worries that unique Cerrado plants, insects and other creatures may vanish before scientists have an opportunity to identify them, much less study them.

“There is a universe to be discovered,” Machado said. “All attention is focused on the Amazon, no one speaks for the Cerrado.”

Reining in the soy boom

That’s beginning to change.

Dozens of groups, including Greenpeace, the World Wildlife Foundation and the Brazilian research group IPAM, last year began pushing for large multinationals to protect the biome. In a document known as the Cerrado Manifesto, they called for immediate action to stop deforestation in the region.

More than 60 companies, including McDonalds, Unilever and Walmart, have signed on so far. The firms have agreed to support measures that would eliminate native vegetation loss in the Cerrado from their supply chains. But in contrast to the 2006 Amazon soy moratorium, the Cerrado Manifesto did not commit signatories to halt purchases of farm products from newly deforested areas.

Walmart and Unilever said they are committed to achieving zero net deforestation in their supply chains by 2020, meaning any destruction in one region would be offset by recuperation of similar forest elsewhere. Walmart said all its beef suppliers in the Cerrado are monitored to ensure they don’t contribute to deforestation there. McDonalds didn’t respond to a request for comment.

Separately, Netherlands-based Louis Dreyfus Company in June became the first major commodity trader to pledge to stop buying soy from newly deforested land specifically in the Cerrado. The company gave no timetable, but said it would work to establish a “realistic target date” to end deforestation in its Cerrado supply chain.

Brazil’s former Minister of Environment Jose Sarney Filho, who recently left office to run for Senate, has proposed an international effort to compensate landowners who preserve natural habitat. He raised the issue at last November’s global climate summit in Germany, but the effort has yet to attract major backers.

Farmer Pansera, meanwhile, sees big things ahead for his patch of the Cerrado. Supervising the harvest on his land earlier this year, he watched a pair of combines chew through rows of soybean plants. The giant machines stripped away the beans and spit them into empty grain trucks rolling just behind to catch the bounty.

He said there is no future without growth, and the frontier region of Matopiba is just getting started. He plans to plant an additional 180 hectares of soy next year on newly cleared land.

“There is still a large area to be opened,” Pansera said. “It will be one of the great centers of Brazilian agriculture.”

India said on Tuesday it expected to spend less than 100 billion rupees ($1.43 billion) on its first manned space mission to be launched by 2022, suggesting it is likely to be cheaper than similar projects by the United States and China.

India is cultivating a reputation as a low-cost space power, after the 2014 launch of an unmanned Mars mission at a cost of $74 million, or less than the budget of the Hollywood space blockbuster Gravity and a fraction of the $671 million the U.S. space agency NASA spent on its MAVEN Mars mission.

The Indian manned mission, announced this month by Prime Minister Narendra Modi and to be led by the Indian Space Research Organization (ISRO), will aim to send a three-member crew to space for five to seven days in a craft that will be placed in a low Earth orbit of 300-400 km, the Department of Space said in a statement.

“ISRO has developed some critical technologies like re-entry mission capability, crew escape system, crew module configuration, thermal protection system, deceleration and floatation system, sub-systems of life support system etc required for this program,” the statement said.

ISRO Chairman K. Sivan said the agency had “perfected the engineering aspects of the mission,” although it was new to the field of bioscience — dealing with living beings.

Private agencies will also participate in the mission, and ISRO might consider collaborations with space agencies from “friendly countries with advanced space programs,” the statement added.

India’s neighbor and old rival China first sent humans to space in 2003, becoming only the third country to have such capability after Russia and the United States.

China’s Shenzhou program is secretively run through military and government agencies and its budget is not public. In 2003, officials said it had cost 18 billion yuan ($2.62 billion).

India’s space program has a total budget of around $4 billion, and Modi’s government hopes recent satellite launches — many on behalf of foreign governments — would improve its prospects of winning a larger share of the more than $300 billion global space industry.

Earlier this month, NASA unveiled its analysis of data collected from lunar orbit by an Indian spacecraft. The findings marked the first time scientists confirmed by direct observation the presence of water on the moon’s surface — in hundreds of patches of ice deposited in the darkest and coldest reaches of its polar regions.

Indonesia produces an estimated 1.3 million tons of plastic every day, much of which ends up in the oceans, clogging the ecosystem and killing wildlife. Last year the country pledged to cut the amount it throws into the sea by 70 percent by 2025. As Jack Hewson reports, the sea itself could help to solve the problem.
