How can we bring disappearing sparrows back to our cities? (downtoearth)

In 2012, the then Chief Minister of Delhi, Sheila Dikshit, declared house sparrow as the state bird of Delhi. Two years prior to that, the Indian Postal Department had released a stamp of the house sparrow along with the rock pigeon. But what was once the most ubiquitous bird is now fast disappearing from our neighbourhood.

Once again, the blame goes to us, humans, who have robbed them of their food and nesting places. Our indifference is pushing them to the edge of extinction.

Sparrows are rendered homeless due to modern "matchbox styled" architecture that makes it difficult for the bird to build nests. These winged companions, who used to build nest in holes, roofs and crevices on traditional houses, are struggling to find a safe corner in glass buildings. It also explains why South Mumbai sees a comparatively larger sparrow population than the western suburbs.

Like sparrows, cavities are important for mynahs and parakeets to make nests.

Blaming the possible extinction of sparrows on mindless urbanisation, Mohammed Dilawar, a conservationist and the founder of The Nature Forever Society, says that the bird is losing its natural habitat and “also the essential human touch they need and thrive upon”. Speaking to Down To Earth about the ‘Great Sparrow Count’ initiative that his organisation has embarked upon, he says, “Historically, we never thought of counting sparrows around us. It never occurred to us that their numbers are declining. In a first-of-a-kind mass outreach programme, especially focussed on India, we are trying to document the population and distribution of 24 different species of sparrows by asking people to monitor and count their number. Once we get the data, we will be able to arrive at a conclusion on total count and its distribution. We intend to make it an annual programme.”

Not just pesticides used during agriculture, but the chemicals used while storing grain, ultimately find way to the system of a sparrow, causing them to die, says P A Azeez, former director of Sálim Ali Centre for Ornithology and Natural History (SACON). “Unlike conventional shops where we used to pack grains and pulses in paper bags, making some allowance for spillage, the plastic bags in departmental stores don’t allow that spillage, which explains the scarcity of food for these poor birds,” he adds.

So what can we do at our level to arrest this trend? “Make holes in your homes. Help them find a safe nesting place,” he quips.

Sparrows losing their lives because of our lifestyle

The depleting population of sparrows is also attributed to increased use of packaged food. Unlike the earlier days, when women used to clean grain outside their houses and sparrows would have plenty of food from there, the bird is either starved or forced to eat leftover from the packaged foods.

Extensive use of pesticides and insecticides in farms and gardens is also killing the bird’s primary food source: insects.

With native plants like adulsa and mehndi are being fast replaced by non-native plants to aid modern landscaping, the sparrows are losing insects like aphids to feed on. Sparrows need a diet of insects and worms like caterpillars that serve as a protein supplement, particularly during growing up phase of their life.  Apart from declining number of insects that they feed on, contemporary landscaping is also doing away with hedges—preferred nesting places for sparrows.

Back in 2011, the expert committee under the Ministry of Environment, Forests and Climate Change (MoEF&CC), had admitted that electromagnetic radiation (EMR) is largely responsible for the bird's declining numbers. The panel had suggested recognising EMR as a pollutant because of their possible effect on animals and birds. It also pointed out how common house sparrows have declined in numbers in Nagpur, Bhopal, Jabalpur, Ujjain and other cities due to an increasing use of mobile phones.

Sparrows are indicators of environmental health and changes in the urban ecosystem.

What can we do to arrest this decline?

According to the founder of Sparrow’s Shelter, Pramod Mane, under whose request the then CM of Delhi declared sparrow as the state bird, “During summers, people should hang artificial bird nests in balconies and put out a pot of water and food for the winged visitors.”  Sparrow’s Shelter was the first organisation in Mumbai to introduce the idea of bird houses in 2008.

“If we cannot save sparrows, no one else can. In few decades, they would go extinct like dinosaurs. My organisation is trying to make people aware of their responsibility to save the bird because they are only one responsible for their deaths,” says Mane. Sparrows were included under the ‘threatened’ category in the IUCN list.

While we wait for the government to take note of the trend, at an individual level, we can do our bit:

Kitchen waste could be transferred into bio-manure and the decomposition would help in the development of microbes that these birds feed on.
Besides water bowls, bird-bath in hot summer afternoon helps birds to rehydrate.
Plants and hedges, that are native to the place, can be grown. This encourages sparrows to come back.
Sparrows breed four times a year. Artificial nests outside our homes can help them have a constant and safe place for breeding and to roost.

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
