Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, May 13: Union Finance Minister Nirmala Sitharaman will address a press conference in New Delhi at 4 pm on Wednesday.

The information regarding the press conference by the Union Finance Minister was given through a tweet by the Ministry of Finance today morning.

Sitharaman's press conference comes a day after Prime Minister Narendra Modi announced USD 265 billion fiscal stimulus to deal with COVID-19 situation in the country. The package is the second largest in Asia after Japan.

"I announce a special economic package today. This will play an important role in the 'Atmanirbhar Bharat Abhiyan.' The announcements made by the government over COVID, decisions of RBI and today's package totals to Rs 20 lakh crore (USD 265 billion). This is 10 per cent of India's GDP," the Prime Minister said in his address to the nation on Tuesday.

"This economic package is for our small-scale industries, MSMEs, which are the means of livelihood of crores of people and is the strong base of our resolve for self-reliant India. To prove the resolve of self-reliant India, the emphasis has been given on land, labour, liquidity and laws, in this package," he added.

The PM had also said that the economic package is for "the country's workers, farmers, who are working hard day and night for the countrymen in every season. This economic package is for the middle class of our country, who pays tax honestly and contributes to the development of the country."

He had announced that the fourth phase of the nationwide COVID-19 induced lockdown would be in "new form with new rules."

New Delhi, Jan 12: As many as 109 children were sexually abused every day in India in 2018, according to the data by the National Crime Records Bureau, which showed a 22 per cent jump in such cases from the previous year.

According to the recently released NCRB data, 32,608 cases were reported in 2017 while 39,827 cases were reported in 2018 under the Protection of Children from Sexual Offences Act (POCSO).

POCSO Act, 2012 is a comprehensive law to provide for the protection of children from offences of sexual assault, sexual harassment and pornography. It requires special treatment of cases relating to child sexual abuse such as setting-up of special courts, special prosecutors, and support persons for child victims.

As many as 21,605 child rapes were recorded in 2018 which included 21,401 rapes of girls and 204 of boys, the data showed.

The highest number of child rapes were recorded in Maharashtra at 2,832 followed by Uttar Pradesh at 2023 and Tamil Nadu at 1457, the data showed.

Overall crimes against children has increased steeply over six times in the decade over 2008-2018, from 22,500 cases recorded in 2008 to 1,41,764 cases in 2018, according to the NCRB data from 2008 and 2018.

In 2017, 1,29,032 cases of crime against children were recorded.

Priti Mahara, Director of Policy Research and Advocacy at CRY – Child Rights and You (CRY) said, that while on the one hand, the increasing numbers of crimes against children are extremely alarming, it also suggests an increasing trend in reporting which is a positive sign as it reflects people's faith in the system.

"It also provides a direction in which government interventions must be made and evidence needs to be created. While some major efforts have been taken to ensure child protection, a lot more is needed to see expected results on the ground," Mahara said.

In percentage terms, major crime against children during 2018 were kidnapping and abduction which accounted for 44.2 per cent followed by cases under POCSO, which accounted for 34.7 per cent, the data showed.

A total of 67,134 children (19,784 male,47,191 female and 159 transgender) were reported missing in 2018. During the year 2018, a total of 71,176 children (22,239 male, 48,787 female and 150 transgender) were traced, the NCRB data said.

As many as 781 cases of use of child for pornography or storing child pornography material was also recorded in 2018, more than double that of  2017 when 331 such cases were recorded, the data showed.

The state-wise segregation of crimes against children reveals Uttar Pradesh, Madhya Pradesh, Maharashtra, Delhi and Bihar accounted for 51 per cent of all crimes in the country, the data said.

While Uttar Pradesh tops the list with 19,936 recorded crimes against children (14 per cent of total crimes), Madhya Pradesh and Maharashtra are the close second and third with 18,992 and 18,892 crimes registered respectively.

The report also showed that cases of sexual harassment in shelter homes against women and children reportedly increased by 30 per cent, from 544 cases recorded in 2017 to 707 cases in 2018.

Mahara suggested that financial investments must be adequately increased with a focus on prevention of crimes against children and the identification of vulnerable children and families.

"Strengthening community-level child protection system is also a key to prevention. While there is growing evidence of the precarious lives that children in India are leading, it is essential that this evidence is used to effectively inform policy and programme initiatives," she said.

As many as 501 incidences were also recorded under The Prohibition of Child Marriage Act, a 26 per cent jump from 2017 when 395 cases were reported under the Act.
