Row at Allahabad univ escalates, Oppn targets Irani

New Delhi, April 6: Prime Minister Narendra Modi on Monday said that people from every section of the society and age group demonstrated unity on Sunday by responding to the Prime Minister '9 pm-9minute' appeal and strengthened the resolve to the fight against COVID-19.

"We experienced yesterday at 9 pm, the strength of togetherness of 130 crores people of our country," said PM Modi.

He further praised the citizens of the country for their support to the lockdown imposed across India in the wake of coronavirus threat.

"The maturity shown by the people during the lockdown, in a large country like India, is unprecedented. No one could have imagined that the people will abide by this with such obedience and sense of service," said Prime Minister Modi.

"I state it with full responsibility that this is a long war against coronavirus pandemic. But we do not have to get tired or take a rest in this war. We have to emerge victoriously. Today, the country has only one goal and one resolve - to win this war," he added.

The Prime Minister continued saying, that the government has developed an Aarogya Setu app through which one can get information regarding the infected cases around them.

"I request all of you to tell people about it, everyone should make sure that at least 40 others install it. They will get info through it about possibly infected cases around them. In these tough times, we have to ensure this," he added.

The Prime Minister also advised everyone to take necessary preventive measures and stay protected by adopting the mantra of social distancing.

"Always remember, whenever you go out your face should be covered, I say you should keep your face covered even at your homes. The mantra today for the whole world is social distancing and discipline," he added.

Prime Minister Modi addressed the BJP workers and the nation on the occasion of the Bharatiya Janata Party's (BJP) 40th Foundation Day.

New Delhi, Jan 24: Although India's Ujjwala programme encouraged adoption of liquefied petroleum gas (LPG) for cooking among the poor, households availing the scheme have not shifted away from using highly polluting fuels like firewood, a study reveals.

The researchers, including those from the University of British Columbia (UBC) in Canada, found that additional incentives to encourage regular use of cooking gas are necessary for a complete transition to clean cooking fuel among poor rural households.

They noted that about 2.9 billion people across Asia, Africa, and Latin America burn solid fuels like firewood to meet their cooking energy needs.

This has significant negative implications for public health, the environment, and societal development, according to the researchers.

Through the Pradhan Mantri Ujjwala Yojana (PMUY), India has provided capital cost subsidies to poor women to adopt a clean-burning cooking fuel or LPG.

The researchers explained that within the first 40 months of the scheme, more than 80 million households obtained LPG stoves.

However, the full benefits of LPG adoption depend on near complete replacement of polluting fuels with LPG, according to a research-based policy brief published in the journal Nature Energy.

The scientists said this cannot be assumed solely on the basis of LPG presence in the household.

"Our research shows that Ujjwala was able to attract new consumers rapidly, but those consumers did not start using LPG on a regular basis," Abhishek Kar, a postdoc at Columbia University in the US, told PTI.

The study analysed LPG sales data for over 25,000 consumers, including PMUY beneficiaries, as well as general rural LPG consumers in Koppal district of Karnataka.

The scientists employed data covering all LPG purchases of PMUY beneficiaries through their first year in the programme.

They also assessed the general rural population's purchases during their first five years as consumers to assess the effect of experience on use.

The findings estimate that an average rural family needs to purchase five 14.2 kilogramme-cylinders annually to meet half of their cooking needs.

However, the study said just seven per cent of PMUY beneficiaries in Koppal purchased five or more cylinders annually, suggesting that the beneficiaries seldom use LPG.

The general (nonPMUY) consumers in this region use on average two times more LPG cylinders than PMUY beneficiaries, the researchers noted.

Yet, only 45 per cent of nonPMUY consumers use five or more cylinders per year -- even after several years of experience with LPG, they said.

The team assessed price and seasonal factors affecting LPG use among the general population over a three-year period.

It found that LPG consumers are sensitive to price and seasonality -- LPG cylinder refill rates are lower in the summer when agricultural activity is limited, and cash is scarce.

"There was no scheme incentives to promote use, except general LPG subsidies which is available to all, including the urban middle class," said Kar, who was a Ph.D. scholar at UBC when the research was published.

"If there is no additional income, what cost would a poor family on an already tight budget cut to pay for an extra expense on a regular basis.

"Ujjwala has started the scheme of 5 kg-cylinder in response, but the impact of that on LPG sales is still publicly unknown," he said.

These findings, the researchers noted, suggest the need for additional measures to promote regular LPG use for all rural populations.

Although the finding come from a single district in Southern India, it may also apply to other areas with similar socio-economic conditions, they said.

A more expansive evaluation of PMUY would help design targeted incentives to transform infrequent users to regular users, according to the researchers.
