Scientists suggest early warning system for forest fires (downtoearth)

A team of Indian scientists has proposed a new strategy to tackle forest fires, the numbers of which are on the rise in recent years in the wake of climate change.

The strategy involves providing for greater involvement of local communities and use of modern tools of communication technologies such as mobile apps. The aim is to put together a mechanism for an early warning system and cover a much larger area than at present.

Techniques are available for detecting forest fires even now. However, their utility is largely confined to big fires of long durations. Their efficiency remains in doubt for detecting small fires of short duration, which are as important. For instance, during last year, when there was a continuous increase in air temperature from late January 2016 and no or minimal rainfall since October 2015 in Uttarakhand, fires started erupting from February and reached their zenith in April and May with fresh leaf litter on the forest floor adding fuel to the flames. In all, about 4,430 hectares of forest land was reportedly affected by fire during the year.

One of the most striking features of the disaster was that as much as 35 per cent of the fire happened outside reserve forests. The new strategy seeks to address this issue by getting local people on board.

Subrat Sharma and Harshit Pant of Almora-based G B Pant National Institute of Himalayan Environment and Sustainable Development, who have developed the new strategy, noted, that the Forest Department recruits fire watchers but it is impossible for them to reach everywhere. Instead, local populations could be roped in and pooled in as a vast network using mobile phones. Simple Apps could be developed for sending and receiving fire-related information and other observations in text, photographs and other forms and tagged in real time for geo-referencing.

A fire potential index could also be developed, based on inputs received from various locations with regards to ground conditions such as temperature variations, rainfall occurrences, leaf fall intensities and status of leaf litter. All this information could then be routed to decision-making organisations such as fire control centres equipped with modern decision support systems for necessary action, scientists have suggested in a paper published in the latest issue of the journal, Current Science. In addition, preservation of community forests should be incentivised. (India Science Wire)

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment]. Having

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i
