Reserve may submerge in Ken-Betwa project

September 25, 2016

New Delhi, Sep 25: About 7.2 lakh trees and a huge 90 square kilometres area of Panna Tiger Reserve (PTR) may be submerged in water due to the Ken-Betwa river linking project, according to an official report.

There will be also be an "irreversible" loss of breeding sites for wild animals after submergence of critical and specialised habitats under the proposed project which is likely to cost over Rs 9,000 crore.

The Ken-Betwa project is expected to provide drinking water supply for 13.42 lakh people and help irrigate 6.75 lakh hectares of land in the poverty-ridden Bundelkhand region covering parts of Madhya Pradesh and Uttar Pradesh.

The project is founded on construction of a dam at Dhaudan village inside the PTR's core area in Chhatarpur district of Madhya Pradesh.

"The entire forest area under the proposed submergence both within and outside PTR is tiger habitat, while the non-forest area is potential tiger habitat. Thus, about 90 sq km area of tiger habitat, including potential habitat, will have to be considered as submergence zone," National Board of Wildlife (NBWL) Standing Committee report on Ken-Betwa link project said.

At present, there are around 35 tigers in the reserve, which had in 2009 reported extinction of the big cats.

The report, which has been submitted to Union Environment Ministry, said the total counting of trees in the proposed submergence area has not been done, but a sample survey by the forest department has estimated that "about 7.2 lakh trees above 20 cm girth at breast height would submerge in the national park area and this number may go up to about 12 lakh stems when young poles and established sapling are accounted".

It said an equally high number of trees will be cut or lost in the forest areas outside the national park. "Thus considerable quantity of carbon stored as biomass would be released once the dam is constructed, in addition to loss of vegetation diversity," said the report, a copy of which was received by wildlife activist Ajay Dubey in response to an RTI query filed by him.

He said the National Green Tribunal and appropriate court will be approached to challenge the proposed project on the basis of the report's findings. The report said Panna Tiger Reserve has largely been valued with respect to the requirement of the tiger.

"The importance of other key wildlife such as sloth bear, leopard, rusty spotted cat, hyena, sambhar, chital, four-horned antelope and chinkara are largely ignored under the shadow of tiger, although tiger conservation may support the conservation of its associated fauna. Ken river along with its tributary is a lifeline of the park. Ken river basin is full of gorges, caves, rock crevices which are normally occupied by wild mammals for breeding and resting.

"During hot days in summer, these gorges, caves, rock crevices are major shelters for some of the animals listed above. Loss of breeding sites will be irreversible after submergence of these critical and specialised habitats, specifically in the major submergence zone," it said.

The blasting of stone quarries, use of heavy machinery, movement of heavy vehicles and presence of over 500 workers (at a time) for construction are some of the "major concerns", the report said.

"Given that the region (Bundelkhand) is poverty-ridden, the realised benefit of the project cannot be ignored and that there would certainly be a need to strike a balance between wildlife conservation and people's livelihood considerations," it said. The estimated cost of Ken-Betwa project is Rs 9,393 crore.

New Delhi, Mar 8: In order to spread awareness, a special COVID-19 mobile phone caller tune was launched by all telecom operators with basic infection prevention messages played when a caller dials-out, Ministry of Health and Family Welfare said on Saturday.

"In order to spread awareness about COVID-19, a special COVID-19 mobile phone caller tune was launched by all telecom operators. Over 117.2 crore subscribers of BSNL, MTNL Reliance Jio, Airtel and Vodafone-Idea are being progressively reached out to through SMSs and Call Backs," Ministry of Health and Family Welfare said in a press statement.

"As many as 52 laboratories are now operational across the country for testing the COVID-19 virus. An additional 57 laboratories have been provided with Viral Transport Media and swabs for sample collection," the statement added.

India has 39 confirmed cases of deadly coronavirus so far. The disease has caused deaths of 3200 people globally.

London, Feb 21: Scientists have discovered a new species of land snail, and have named it Craspedotropis Greta Thunberg in honour of the Swedish activist Greta Thunberg for her efforts to raise awareness about climate change.

According to the study, published in the Biodiversity Data Journal, the newly discovered species belongs to the so-called caenogastropods -- a group of land snails known to be sensitive to drought, temperature extremes, and forest degradation.

The scientists, including evolutionary ecologist Menno Schilthuizen from Naturalis Biodiversity Center in the Netherlands, said the snails were found very close to the research field station at Kuala Belalong Field Studies Centre in Brunei.

They added that the snails were discovered at the foot of a steep hill-slope, next to a river bank, foraging at night on the green leaves of understorey plants.

The effort aided by amateur scientist J.P. Lim, who found the first individual of the snail said, "Naming this snail after Greta Thunberg is our way of acknowledging that her generation will be responsible for fixing problems that they did not create."

"And it's a promise that people from all generations will join her to help," Lim said.

The researchers said they approached Thunberg who said that she would be "delighted" to have this species named after her.

The study work including, fieldwork, morphological study, and classification of identified specimen was carried out in a field centre with basic equipment and no internet access, the scientists said.

According to the study, the work was done by untrained ‘citizen scientists’ guided by experts, on a 10-day taxon expedition.

"While we are aware that this way of working has its limitations in terms of the quality of the output (for example, we were unable to perform dissections or to do extensive literature searches), the benefits include rapid species discovery and on-site processing of materials," the researchers wrote in the study.

Los Angeles, Apr 28: People who experience loss of smell as one of the COVID-19 symptoms are likely to have a mild to moderate clinical course of the disease, according to a study which may help health care providers determine which patients require hospitalisation.

The findings, published in the journal International Forum of Allergy & Rhinology, follows an earlier study that validated the loss of smell and taste as indicators of infection with the novel coronavirus, SARS-CoV-2.

According to the scientists from the University of California (UC) San Diego Health in the US, patients who reported loss of smell were 10 times less likely to be hospitalised for COVID-19 compared to those without the symptom.

"One of the immediate challenges for health care providers is to determine how to best treat persons infected by the novel coronavirus," said Carol Yan, first author of the current study and rhinologist from the UC San Diego Health.

"If they display no or mild symptoms, can they return home to self-quarantine or will they likely require hospitalisation? These are crucial questions for hospitals trying to efficiently and effectively allocate finite medical resources," Yan said.

The findings, according to the researchers, suggest that loss of smell may be predictive of a milder clinical course of COVID-19.

"What's notable in the new findings is that it appears that loss of smell may be a predictor that a SARS-CoV-2 infection will not be as severe, and less likely to require hospitalisation," Yan said.

"If an infected person loses that sense, it seems more likely they will experience milder symptoms, barring other underlying risk factors," she added.

Risk factors for COVID-19 previously reported by other studies include age, and underlying medical conditions, such as chronic lung disease, serious heart conditions, diabetes, and obesity.

In the current study, the scientists made a retrospective analysis between March 3 and April 8 including 169 patients who tested positive for COVID-19 at UC San Diego Health.

They assessed olfactory and gustatory data for 128 of the 169 patients, 26 of whom required hospitalisation.

According to the researchers, patients who were hospitalised for COVID-19 treatment were significantly less likely to report anosmia or loss of smell -- 26.9 per cent compared to 66.7 per cent for COVID-19-infected persons treated as outpatients.

Similar percentages were found for loss of taste, known as dysgeusia, they said.

"Patients who reported loss of smell were 10 times less likely to be admitted for COVID-19 compared to those without loss of smell," said study co-author Adam S. DeConde.

"Moreover, anosmia was not associated with any other measures typically related to the decision to admit, suggesting that it's truly an independent factor and may serve as a marker for milder manifestations of Covid-19," DeConde said.

The researchers suspect that the findings hint at some of the physiological characteristics of the infection.

"The site and dosage of the initial viral burden, along with the effectiveness of the host immune response, are all potentially important variables in determining the spread of the virus within a person and, ultimately, the clinical course of the infection," DeConde said.

If the SARS-CoV-2 virus initially concentrates in the nose and upper airway, where it impacts olfactory function, that may result in an infection that is less severe and sudden in onset, decreasing the risk of overwhelming the host immune response, respiratory failure, and hospitalisation, the scientists added.

"This is a hypothesis, but it's also similar to the concept underlying live vaccinations," DeConde explained.

"At low dosage and at a distant site of inoculation, the host can generate an immune response without severe infection," he added.

Loss of smell, according to the study, might also indicate a robust immune response which has been localised to the nasal passages, limiting effects elsewhere in the body.

Citing the limitations of the study, the scientists said they relied upon self-reporting of anosmia from participants, which posed a greater chance of recall bias among patients once they had been diagnosed with COVID-19.

They added that patients with more severe respiratory disease requiring hospitalisation may not be as likely to recognise or recall the loss of smell.

So the researchers said more expansive studies are needed for validating the results.
