Not scared of Pakistan's nuclear bogey, says Lieutenant General Naravane

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.

United Nations, May 21: At least 19 million children in parts of Bangladesh and India are at "imminent risk" from flash flooding and heavy rain as Cyclone Amphan makes landfall and the state of West Bengal is expected to take a direct hit from the powerful storm, the UN's children agency has warned.

The extremely severe cyclonic storm Amphan made a landfall at Digha in West Bengal and Bangladesh on Wednesday, leaving a trail of destruction. At least three persons were killed in India and seven in Bangladesh.

The UNICEF said that at least 19 million children in parts of Bangladesh and India are at “imminent risk from flash flooding, storm surges and heavy rain as Cyclone Amphan makes landfall.”

West Bengal, “home to more than 50 million people, including over 16 million children, is expected to take a direct hit from the powerful storm,” the UN agency said in a statement on Wednesday.

The UNICEF said it is also very concerned that the COVID-19 could deepen the humanitarian consequences of Cyclone Amphan in both the countries. Evacuees who have moved to crowded temporary shelters would be especially vulnerable to the spread of respiratory diseases like COVID-19, as well as other infections.

“We continue to monitor the situation closely,” said UNICEF Regional Director for South Asia Jean Gough.

“The safety of children and their families in the areas that will be impacted is a priority and it is good to see that the authorities have planned their urgent response factoring in the on-going COVID-19 pandemic.”

Across the region, the UNICEF is “working closely with the governments of Bangladesh and India and stands ready to support humanitarian operations to reach children and families affected by Cyclone Amphan.”

Based on the storm’s current trajectory, Cox’s Bazar in Bangladesh – now sheltering over 850,000 Rohingya refugees – is likely to experience high winds and heavy rains which may cause damage to homes and shelters in the refugee camps and Bangladeshi communities. This population is already highly vulnerable and cases of COVID-19 have recently been confirmed in the camps and host communities.

The UNICEF said it is working with the Deputy Commissioner’s Office in Cox’s Bazar, the Office of the Refugee Relief and Repatriation Commissioner, and humanitarian partners to help ensure Bangladeshi and Rohingya children and families remain protected.

These efforts include raising awareness among Rohingya and Bangladeshi communities on cyclone preparedness and prepositioning emergency life-saving water, sanitation, hygiene and medical supplies to meet immediate humanitarian needs.

Meanwhile, UN Secretary-General Antonio Guterres’ spokesperson Stephane Dujarric said at the daily press briefing that UN teams on the ground continue to work with the Government of Bangladesh to prepare and support those in need in the wake of the cyclone.

“Given the current pandemic, this support includes distributing personal protective equipment, disinfectants and other materials to evacuation shelters. To reduce the person-to-person contact during the delivery of aid, e-cash distributions will be used,” he said adding that the UN along with its partners is mobilising more than 1,700 mobile health teams and preparing for emergency food deliveries.

“The Super Cyclone is taking a westerly trajectory towards India, but nearly 8 million people in Bangladesh remain at risk,” he said adding that the Bangladesh government has evacuated more than 2 million people in high-risk areas. 

New Delhi, Jun 15: Two officials working with the Indian High Commission in Islamabad have reportedly gone missing, sources said.

The two officials are untraceable for the last few hours.

Recently news agency reported on how Pakistan 's spy agency ISI has been tailing and harassing Indian officials and also increased their presence at the residence of Acting High Commissioner Gaurav Ahluwalia.

This incident came in the backdrop when two Pakistani officials were caught red-handed and sent back trying to collect classified information and spying in Delhi.

South block is watching the developments closely, the Indian mission has also launched a complaint with local authorities and taken up the matter Pakistan Foreign Ministry.

This incident can cause a further dip in the already tense India-Pakistan relations.

Earlier in the month, India deported two Pakistani officials for espionage activities in India.
