'Himalayan Viagra' Dearer Than Gold under Threat from Climate Change

Washington, Oct 23: A prized caterpillar fungus that is more valuable than gold and is nicknamed "Himalayan Viagra" in Asia, where it is seen as a wonder drug, is becoming harder to find due to climate change, researchers said on Monday.

People in China and Nepal have been killed in clashes over the years over the elusive fungus "yarchagumba”, known formally as Ophiocordyceps sinensis.

Although it has no scientifically proven benefits, people who boil yarchagumba in water to make tea or add it to soups and stews believe it cures everything from impotence to cancer.

It is "one of the world's most valuable biological commodities, providing a crucial source of income for hundreds of thousands of collectors," said the report in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal.

In recent decades, it has skyrocketed in popularity and prices have soared — it can fetch up to three times the price of gold in Beijing, researchers say.

While many have suspected overharvesting was the reason for its scarcity, researchers wanted to find out more.

So they interviewed around four dozen harvesters, collectors and traders of the prized fungus.

They also scoured previously published scientific literature, including interviews with more than 800 people in Nepal, Bhutan, India and China, to understand its apparent decline.

Weather patterns, geographic factors and environmental conditions were also analyzed to create a map of yarchagumba production in the region.

"Using data spanning nearly two decades and four countries, (we) revealed that caterpillar fungus production is declining throughout much of its range," said the report.

"While collectors increasingly attribute the decline in caterpillar fungus to overharvesting, habitat and production modeling suggest that climate change is also likely playing a role."

Particular temperatures

The cone-shaped fungus is only found above an elevation of 11,500 feet (3,500 meters), and forms when the parasitic fungus lodges itself in a caterpillar, slowly killing it.

To grow, it needs a specific climate that is frigid — with winter temperatures below 0 Celsius (32 Fahrenheit) — but where the soil is not permanently frozen.

"Such conditions are typically present at the margin of permafrost areas," said the PNAS report, led by researchers at Stanford University.

"Given that winter temperatures have warmed significantly from 1979 to 2013 across much of its range, and especially in Bhutan, its populations are likely to have been negatively affected."

The warming trend has particularly affected Bhutan, with average winter temperatures "increasing by 3.5–4 C across most of its predicted habitat (+1.1 C per decade, on average)," added the study.

Researchers also found that vegetation on the Tibetan plateau "did not shift upward in response to climate warming from 2000 to 2014," suggesting that the caterpillar fungus will not be able to simply move up the mountain to colder habitats as the climate warms.

This spells trouble for harvesters who sell the fungus in order to survive, "underscoring the need for alternative livelihood options in the communities that depend on this niche commodity," researchers warned.

Denser places, assumed by many to be more conducive to the spread of the coronavirus that causes COVID-19, are not linked to higher infection rates, say researchers.

The study, led by Johns Hopkins University, published in the Journal of the American Planning Association, also found that dense areas were associated with lower COVID-19 death rates.

"These findings suggest that urban planners should continue to practice and advocate for compact places rather than sprawling ones, due to the myriad well-established benefits of the former, including health benefits," says study lead author Shima Hamidi from Johns Hopkins Bloomberg School of Public Health in the US.

For their analysis, the researchers examined SARS-CoV-2 infection rates and COVID-19 death rates in 913 metropolitan counties in the US.

When other factors such as race and education were taken into account, the authors found that county density was not significantly associated with county infection rate.

The findings also showed that denser counties, as compared to more sprawling ones, tended to have lower death rates--possibly because they enjoyed a higher level of development including better health care systems.

On the other hand, the research found that higher coronavirus infection and COVID-19 mortality rates in counties are more related to the larger context of metropolitan size in which counties are located.

Large metropolitan areas with a higher number of counties tightly linked together through economic, social, and commuting relationships are the most vulnerable to the pandemic outbreaks.

According to the researchers, recent polls suggest that many US citizens now consider an exodus from big cities likely, possibly due to the belief that more density equals more infection risk.

Some government officials have posited that urban density is linked to the transmissibility of the virus.

"The fact that density is unrelated to confirmed virus infection rates and inversely related to confirmed COVID-19 death rates is important, unexpected, and profound," said Hamidi.

"It counters a narrative that, absent data and analysis, would challenge the foundation of modern cities and could lead to a population shift from urban centres to suburban and exurban areas," Hamidi added.

The analysis found that after controlling for factors such as metropolitan size, education, race, and age, doubling the activity density was associated with an 11.3 per cent lower death rate.

The authors said that this is possibly due to faster and more widespread adoption of social distancing practices and better quality of health care in areas of denser population.

The researchers concluded that a higher county population, a higher proportion of people age 60 and up, a lower proportion of college-educated people, and a higher proportion of African Americans were all associated with a greater infection rate and mortality rate.

Bengaluru, Mar 13: In the wake of fresh cases of Covid-19 reported in Karnataka, Infosys Foundation chairperson Sudha Murty has urged the Karnataka government to take steps to shut malls and theatres, saying the coronavirus multiplies in air-conditioned areas.

In a letter to the government, she said preventive measures should be taken to control the spread of coronovirus before it gets worse.

Murty, who also leads the State government-constituted Karnataka Tourism Task Force, said she has discussed the current situation with Chairman and Executive Director of Narayana Health, Devi Prasad Shetty.

She suggested closure of all schools and colleges with immediate effect, malls, theatres and “all air-conditioned areas where the virus multiplies”, and allow only essential services like pharmacy, grocery and petrol bunks.

“It is not scientifically proven that the virus dies in high temperature,” she said pointing to spread of the virus -- despite heat -- in peak summer in Australia and Singapore, which have “summer all 12 months”.

“I request you to vacate one government hospital with at least 500 - 700 beds for this purpose (to deal with coronavirus cases), which requires oxygen lines and pipes,” she said.

“Infosys Foundation, the philanthropic and CSR arm of software major Infosys, would do the civil work and Devi Shetty has agreed to share resources like medical equipment,” she added.

“We would like to work with the government proactively so that we can prevent this as early as possible,” Sudha Murty said.

The total number of confirmed coronavirus positive cases in Karnataka is five, including the 76-year old man from Kalaburagi who died on Tuesday night.

Claiming that e-commerce giants like Amazon import as much as 80 per cent of the items sold on their platforms, small manufacturers' body has said that their business models do not benefit local industry and are creating jobs of delivery boys only.

"Neither manufacturers nor traders are getting any benefit from the business models of Amazon and Flipkart because they largely import their products from China and Korea and sell here. Nearly 80 per cent of their products are imported," said Anil Bhardwaj, Secretary General, Federation of Indian Micro and Small & Medium Enterprises (FISME).

Bhardwaj said that the global e-commerce players generally source and sell products through their own preferred suppliers and as a result a large number of local manufacturers and traders get crowded out.

He listed out deep discounting and buying products from preferred companies as unfair practices.

"Even if they buy products from local suppliers the commission charged is very high," Bhardwaj said adding that the issues related to unfair practices have been raised with Commerce Ministry on multiple occasions.

FISME maintains that the technology-driven retail is way forward and one cannot be oblivious of the benefits it brings to consumers but at the same time the local industry can also not be ignored given its role in job creation.

"If both traders and local manufacturers are crowded out then how would the local industry survive and employment be generated?" asked Bhardwaj.

As Amazon Founder and CEO Jeff Bezos is currently on his three-day visit to India, the local traders are up in arms against the "unfair" trade practices of the tech giant. Delhi-based Confederation of All India Traders (CAIT) has launched a countrywide protest against the company and has organised protests across 300 cities.

In a setback to Amazon and Walmart-backed Flipkart, the fair market watchdog Competition Commission of India (CCI) has ordered probe into the business operations of both the companies on multiple counts including deep-discounts and exclusive tie-up with preferred sellers.

"For the first time some concrete step has been taken against Amazon and Flipkart who are continuously violating the FDI policy in indulging in a vicious racket of controlling and monopolising not only the e-commerce but even the retail trade as well," CAIT National Secretary General Praveen Khandelwal said after the CCI order.
