On Yaji Mountain in southern China, they are checking in the sows a thousand head per floor in high-rise “hog hotels.”

Privately owned agricultural company Guangxi Yangxiang Co Ltd is running two seven-floor sow breeding operations, and is putting up four more, including one with as many as 13 floors that will be the world’s tallest building of its kind.

Hog farms of two or three floors have been tried in Europe.

Some are still operating, others have been abandoned, but few new ones have been built in recent years, because of management difficulties and public resistance to large, intensive farms.

Now, as China pushes ahead with industrialization of the world’s largest hog herd, part of a 30-year effort to modernize its farm sector and create wealth in rural areas, companies are experimenting with high-rise housing for pigs despite the costs.

The “hotels” show how far some breeders are willing to go as China overhauls its farming model.

“There are big advantages to a high-rise building,” said Xu Jiajing, manager of Yangxiang’s mountain-top farm.

“It saves energy and resources. The land area is not that much but you can raise a lot of pigs.”

Companies like Yangxiang are pumping more money into the buildings — about 30 percent more than on single-story modern farms — even as hog prices in China hold at an eight-year low.

For some, the investments are too risky. Besides low prices that have smaller operations culling sows or rethinking expansion plans, there is worry about diseases spreading through such intensive operations.

But success for high-rise pig farms in China could have implications across densely populated, land-scarce Asia, as well as for equipment suppliers.

“We see an increasing demand for two- or three-level buildings,” said Peter van Issum, managing director of Microfan, a Dutch supplier that designed Yangxiang’s ventilation system.

Microfan also supplied a three-story breeding operation, Daedeok JongDon GGP Farm, in South Korea.

“The higher ones are still an exception, but the future might change rapidly,” van Issum said.

High-rise hogs

Yaji Mountain seems an unlikely location for a huge breeding farm. Up a narrow road, away from villages, massive concrete pig buildings overlook a valley of dense forest that Yangxiang plans to develop as a tourist attraction.

The site, however, is relatively close to Guigang, a city with a river port and waterway connections to the Pearl River Delta, one of the world’s most densely populated regions.

While Beijing is encouraging more livestock production in China’s grain basket in the northeast, many worry that farms there will struggle to get fresh pork safely to big cities thousands of miles away.

That has helped push some farm investments to southern provinces like Guangxi and Fujian, where land is hilly but much closer to many of China’s biggest cities.

Yangxiang will house 30,000 sows on its 11-hectare site by year-end, producing as many as 840,000 piglets annually. That will likely make it the biggest, most-intensive breeding farm globally. A more typical large breeding farm in northern China would have 8,000 sows on around 13 hectares.

In Fujian province, Shenzhen Jinxinnong Technology Co Ltd also plans to invest 150 million yuan ($24 million) in two five-story sow farms in Nanping. Two other companies are building high-rise hog farms in Fujian as well, according to an equipment firm involved in the projects.

Thai livestock-to-retail conglomerate CP Foods is also building four six-story pig units with local firm Zhejiang Huatong Meat Products Co in Yiwu, a Chinese city near the large populations around Shanghai.

High-tech complexity

Yangxiang spent 16,000 yuan per sow on its new farm, about 500 million yuan total, not including the cost of the pigs.

Building upward means higher costs and greater complexity, such as for piping feed into buildings, said Xue Shiwei, vice chief operations officer at Pipestone Livestock Technology Consultancy, a Chinese unit of a U.S. farm management company.

“It would save on land but increase the complexity of the structure, and costs for concrete or steel would be higher,” he said.

Health concerns also raise costs, because the risk of rampant disease — an ever-present problem in China’s livestock sector — is higher with more animals under one roof.

Even two-story farms in Europe have sparked worries that pigs will receive less care, said Irene Camerlink, an animal welfare expert at the University of Veterinary Medicine in Vienna who has worked with Chinese farms.

Any outbreak of disease could lead to extensive culling, she said.

Farm manager Xu said Yangxiang reduces the risk of disease by managing each floor separately, with staff working on the same floor every day. New sows are introduced to a building on the top floor, and are then moved by elevator to an assigned level, where they remain.

The ventilation system is designed to prevent air from circulating between floors or to other buildings. Air enters through ground channels and passes through ventilation ducts on each level. The ducts are connected to a central exhaust on the roof, with powerful extraction fans pulling the air through filters and pushing it out of 15-meter high chimneys.

A waste treatment plant is still under construction on Yaji Mountain to handle the site’s manure. After treatment, the liquid will be sprayed on the surrounding forest, and solids sold to nearby farms as organic fertilizer.

The project’s additional equipment — much of it imported — to reduce disease, environmental impact and labor costs, significantly increased Yangxiang’s spending, the company said.

But after testing other models, Yangxiang concluded the multistory building was best. Others are less convinced.

“We need time to see if this model is do-able,” said Xue of the farm management firm, adding that he would not encourage clients to opt for “hog hotels.”

“There will be many new, competing ideas [about how to raise pigs in China],” Xue said, including high-rise farms. Eventually, “a suitable model will emerge.”

Two weeks of climate talks organized by the United Nations ended Thursday as countries failed to resolve differences about implementing the Paris climate accord.

The negotiations will resume in Bangkok in September, where an extra week’s meeting has now been scheduled.

The pact’s 197 signatories have set a December deadline to agree on the precise rules that countries have to stick to under the Paris agreement.

The lack of progress threatens to unravel three years’ worth of work to complete the Paris agreement, a landmark deal reached in 2015 that set a goal to limit fossil-fuel pollution in all nations for the first time and keep global warming below 2 degrees Celsius by the end of the century.

Overall progress at the meeting in Bonn was very slow, with some countries such as China looking to renegotiate aspects of the Paris deal.

Patricia Espinosa, head of the U.N. agency that oversees climate talks, described the package being negotiated as “highly technical and complex.” It aims to ensure that the efforts countries claim they’re making in the fight against global warming can be verified and compared.

The administration of President Barack Obama was widely credited with helping to bring together the diverging interests of rich and poor countries in the drive to secure the Paris deal. His successor, President Donald Trump, withdrew the U.S. from the accord in June 2017. His administration has attacked climate science, saying it questions whether human activity is behind climate change, and is focused on boosting the fossil fuel industry.

Young men who smoke are more likely to have a stroke before age 50 than their peers who avoid tobacco, a small study suggests.

Smoking has long been linked to an increased risk of stroke in older adults, but research to date examining this connection in younger adults has mainly focused on women. For the current study, researchers examined data on 615 men who had a stroke before age 50 and compared their smoking habits to a control group of 530 similar men who didn’t have a history of stroke.

Overall, current smokers were 88 percent more likely to have a stroke than men who never smoked, the study found.

Light smokers who had fewer than 11 cigarettes a day were 46 percent more likely to have a stroke. Heavy smokers with a two pack-a-day habit, or more, were over five times more likely to have a stroke.

‘Simple takeaway’

“The simple takeaway is the more you smoke, the more you stroke,” said lead study author Janina Markidan of the University of Maryland School of Medicine in Baltimore.

Smoking causes inflammation in blood vessels that increases the risk of blood clots forming, which in turn increases the risk of stroke, Markidan said by email.

“Although reducing the number of cigarettes smoked can reduce your risk of stroke, quitting is still the best choice for smokers,” Markidan added.

For the study, researchers focused on what’s known as an ischemic stroke, the most common kind, which occurs when a clot blocks an artery carrying blood to the brain.

Study has limitations

Among the stroke cases included in the study, 239 men had never smoked and 108 were former smokers. Another 103 men smoked less than 11 cigarettes daily, while 97 men smoked between 11 and 20 cigarettes a day and 40 men smoked 21 to 39 cigarettes daily.

An additional 28 men who had strokes smoked more than 40 cigarettes, or two packs, a day.

Most of the men who had strokes in the study were between 35 and 49 years old.

The study wasn’t a controlled experiment designed to prove whether or how smoking habits might directly influence the potential for a stroke in younger men.

Another limitation is that researchers lacked data on other tobacco products participants used in addition to cigarettes, which might influence their risk of stroke, researchers note in the journal Stroke.

Results hold true for younger smokers

The study team also lacked data on other factors that can independently influence the risk of stroke such as alcohol consumption or exercise habits.

Even so, the results suggest the link between smoking and strokes that is well established for older adults also holds true for younger smokers, said Allan Hackshaw, a researcher at University College London in the UK, who wasn’t involved in the study.

“It shows that smoking has a serious impact even when people are younger,” Hackshaw said by email. “Because treatments for stroke are much better now (fewer die from it straight away), many people who suffer one can have long-lasting consequences and physical disabilities at an age when they are usually expected to be working and physically active/fit.”

There’s a budding industry that’s trying to solve the problem of the limp lettuce and tasteless tomatoes in America’s supermarkets.

It’s full of technologists who grow crops in buildings instead of outdoors, short-cutting the need to prematurely harvest produce for a bumpy ride often thousands of miles to consumers in colder climes.

 

More than 30 high-tech companies from the U.S. to Singapore hoping to turn indoor farming into a major future food source, if only they can clear a stubborn hurdle: high costs.

 

These companies stack plants inside climate-controlled rooms, parse out nutrients and water, and bathe them with specialized light. It’s all so consumers can enjoy tasty vegetables year-round using a fraction of the water and land that traditional farming requires. Farmers can even brag the produce is locally grown.

 

But real estate around cities is pricey. Electricity and labor don’t come cheap. And unlike specialty crops like newly legal marijuana, veggies rarely command premium prices. (It’s tough to compete with plants grown in dirt with free sunlight, after all.)

 

Even the best-funded indoor farming company on the planet — Plenty, which has raised nearly $230 million so far — has embraced a longtime farmers’ crutch: government handouts. It hasn’t found any takers yet.

 

“We believe society should consider investing in this new form of agriculture in the way it invested in agriculture in the 1940s,” said Plenty CEO Matt Barnard in a recent interview.

 

Barnard says public aid — in the form of cheaper power — is one way to turn a good but elusive idea into a sustainable venture.

 

Last year, the U.S. paid farmers $9.3 billion in direct support, and subsidized weather-related crop insurance to the tune of $5.1 billion. In a nutshell, Barnard argues that some of that money could be diverted to crops that grow in rain or shine.

 

Plenty grows kale, mixed greens, basil and natural sweetener stevia in a grey, low-rise warehouse complex in the industrial suburb of South San Francisco.

 

Visitors arriving via the back door must don full-body overalls and rubber boots dipped in disinfecting shoe baths before entering the air-tight workspace.

 

Seedlings are grown on flatbeds and bathed in purple light that gives them the look of a 3D movie watched without glasses. Maturing plants are stuffed into columns where they grow sideways, fed by drip irrigation, and irradiated by columns of light-emitting diodes.

 

The plants will be clipped and packaged before heading to stores later this year.

 

But there are some noticeable gaps in the menu. There are no carrots or tomatoes, because long roots that grow down and vines that require human pruning don’t do well on walls.

 

For indoor farms, making money has largely meant shipping in bulk to grocery stores, a conundrum if costs aren’t in line.

 

Investment in indoor farming soared to $271 million last year, up from just $36 million in 2016, according to market research firm Cleantech Group.

 

“The question is, how are they going to scale?” asks Pawel Hardej, CEO of Civic Farms, a vertical farming consultancy in Austin, Texas.

 

There have been plenty of indoor farming failures already.

 

FarmedHere shuttered its operations in Louisville, Kentucky, and Bedford Park, Illinois, in January last year due to cost overruns.

 

Georgia-based PodPonics, which filed for bankruptcy in 2016, cited labor costs as its biggest drag.

 

Google’s X, the search giant’s secretive “moonshot factory,” killed its indoor farming efforts because it couldn’t grow food staples like grains and rice.

 

Even fans of the technology aren’t sure it can beat another sheltered alternative: greenhouses.

 

“Vertical farming to a lot of [investors] is an ‘if’ and a ‘maybe’ versus a ‘when,'” says Cleantech adviser Yoachim Haynes. “The question that needs to be answered is, ‘Can they do it with cheaper electricity and cheaper labor?’ This is not a question that many have been able to answer.”

 

Barnard says Plenty can prosper if it spends 3 to 5 cents per kilowatt hour on power — well below the 10.4 cents that is the average price nationwide, according to the U.S. Energy Information Administration.

 

While Plenty announced plans to build a 100,000 square-foot facility in the Seattle suburb of Kent in November, it said it isn’t in talks about power breaks with any U.S. city now.

 

Most public support has so far been in rebates for energy-efficient lighting, not running costs.

 

Seattle City Light provided $10,000 worth of energy-efficient lighting to an indoor growing facility that helped feed the city’s homeless. But it already offers the lowest power rate of the top 25 cities in America. “That’s the deal that’s on the table,” says spokesman Scott Thomsen.

 

Chicago provided some $344,000 in construction grants since 2008 to The Plant , a former pork processing plant that is home to multiple indoor farms.

 

While that helped with structural improvements, it didn’t help with operations, says John Edel, the president of Bubbly Dynamics LLC, which owns The Plant.

 

Supplying grocery stores in large volumes is “harder than it sounds,” he says. And other ways of obtaining cheap power — like The Plant’s plan to install a bio-gas guzzling turbine — have faced obstacles that make it uneconomical.

 

“There isn’t a whole lot in the way of incentives for farms here,” Edel says. “There needs to be.”

Health officials in the Democratic Republic of Congo are racing to contain an Ebola outbreak announced this week. At least two people are confirmed to have died of the virus in a remote village of the northwestern DRC, very close to the border of the Republic of Congo. Health experts caution against panic, pointing to the DRC’s strong track record in recent years in containing Ebola outbreaks.

The nation’s health minister, Dr. Oly Ilunga, has been keeping people updated on social media, tweeting that on Thursday – some 24 hours after the initial announcement of the outbreak – a team of 12 experts landed in Mbandaka, the city closest to the outbreak.

 

Earlier this week, he said Ebola had been confirmed in two of 17 hemorrhagic fever deaths seen in recent weeks in the northwest village of Bikoro.

The World Health Organization has released $1 million from its emergency fund to respond to this outbreak. WHO and Doctors Without Borders are leading the response, and have sent experts to the site.

Medical group Doctors without Borders told VOA its experts are also in Bikoro.

This is not Congo’s first encounter with the hemorrhagic fever, which causes an acute, serious illness which is often fatal if untreated. The virus derives its name from the place it was first discovered, the Ebola River, a tributary of the Congo river, in 1976. The average survival rate is 50 percent, according to the World Health Organization.

 

“…Last year, there was an Ebola outbreak in part of DRC as well that was contained relatively quickly, so we are hoping to do the same thing this time around, to send quickly teams to the area where the virus has been confirmed to be circulating, to be in position to identify those who are sick, to be in position to identify those who have been potentially exposed, to put in place all those necessary measures that are used every time when there is an Ebola outbreak to try to stop the transmission as fast as possible,” said spokesman Tarik Jasarevic.

This latest outbreak happened in an area near the banks of the Congo River. Because this region is poor in infrastructure, its many waterways are vital for transport and trade activities.

Ebola killed more than 11,000 people in a two-year outbreak that ravaged Guinea, Sierra Leone and Liberia between 2014 and 2016. So far, none of the recent outbreaks in Congo has been connected to that event.

Jasarevic noted that locals also have an important role to play.

“It is really important that communities in this particular area is (cq) engaged, is (cq) working together with authorities in terms of safe burial practices, in terms of proper contact tracing, to be compliant with those procedures,” said Jasarevic. “The community engagement has been proven as a key component in successful containment of an Ebola outbreak.”

 

The virus is transmitted to people from wild animals and is spread person to person through direct contact with bodily fluids, including but not limited to blood, sweat, saliva, breast milk and tears.
