Delhi govt’s Rs 3.2 crore cloud-seeding experiment fails, experts call it costly, unsustainable
New Delhi: Despite high hopes and a hefty budget, Delhi government's much-publicised cloud-seeding experiment has failed to bring significant rainfall, leaving experts questioning the efficacy of the initiative.
The Delhi government’s cloud seeding trials, conducted on Tuesday, have been described as a “hugely expensive, temporary and unsustainable” measure to tackle the capital’s toxic pollution, according to experts cited by the Times of India. Even if artificial rain briefly reduces pollutants, they warn, pollution levels rebound within a day or two.
Under a memorandum of understanding between the Delhi environment department and IIT-Kanpur, over Rs 3.2 crore has been allocated for five cloud-seeding trials — roughly Rs 64 lakh per trial. Three trials conducted in north Delhi failed to produce any major rainfall. Meanwhile, the city’s Air Quality Index (AQI) has continued to hover in the ‘very poor’ to ‘poor’ range.
Anumita Roychowdhury, Executive Director of Research and Advocacy at the Centre for Science and Environment, noted that substantial rainfall has yet to be recorded after cloud seeding. “Even if the rains wash out the pollutants, the pollution will bounce back quickly. The impact lasts from hours to a couple of days,” TOI quoted her as saying.
Roychowdhury added that the initiative is not sustainable and cannot be repeated throughout the winter. She emphasised that investments should focus on reducing emissions at the source for long-term improvements in air quality and public health.
Sunil Dahiya, founder and lead analyst of the think tank EnviroCatalysts, said that improving air quality requires tackling sector-specific emissions from transport, power, and construction. He added that no real impact can be achieved without addressing these sources.
"Cosmetic measures may create short-term visibility benefits but are not sustainable solutions. The focus should instead be on coordinated action across states and agencies through an airshed-based approach that targets the actual sources of pollution," TOI quoted him as saying.
Environmental activist Bhavreen Kandhari pointed out that Delhi’s atmosphere already had enough moisture due to a western disturbance, which naturally brings rain. “Under such circumstances, cloud seeding adds little scientific value; it becomes a costly experiment chasing what nature is already prepared to deliver. Clean air will not come from artificial rain, but from sustained reductions in emissions, dust control, and responsible policy," Kandhari added.
While cloud seeding may seem futuristic, experts stress that Delhi’s true challenge is on the ground, not in the sky. With increasing construction dust, vehicle emissions, and industrial pollution, the city’s air quality cannot be improved through one-off measures. Sustainable progress, they say, depends on strict enforcement of pollution control norms, coordinated regional action, and long-term policy initiatives.

Two held for robbing man on knifepoint
Bengaluru (PTI): Two people have been arrested for allegedly robbing a man at knifepoint after seeking a lift on his two-wheeler, police said on Friday.
The accused, who were apprehended within a day of the complaint, are alleged to have assaulted the victim using a knife and helmet before fleeing with his vehicle, mobile phone and purse.
The victim, a manager at a Kalyana Mantapa in Nellukunte, has lodged a complaint at Chikkajala Police Station on March 26, police said.
He stated that at around 2.30 am on March 25, while heading towards Hunasamaranahalli Road for food, two unidentified persons requested a lift, which he agreed to.
"When they reached near D-Mart on Hosahalli Road, the accused asked him to stop the vehicle. Upon stopping, the accused abused him, assaulted him using a knife and helmet, and robbed his two-wheeler, mobile phone, and purse before fleeing," the release said.
During the investigation, police gathered credible leads and apprehended the two accused near Hunasamaranahalli on March 26.
"Upon interrogation, both accused confessed to their involvement in the offence," it said.
Based on their disclosure, the stolen two-wheeler, knife, helmet, purse and a mobile phone were recovered.
The total value of the recovered property was pegged at Rs 2.20 lakh.
The accused were produced before a court on March 27 and remanded to judicial custody, police said.
