Delhi Plans to Use Cloud Seeding to Induce Artificial Rain to Combat Air Pollution

New Delhi: The Delhi government is exploring the use of cloud seeding technology to alleviate the city’s severe air pollution crisis. A team of scientists from IIT-Kanpur is developing a proposal for this initiative, which is expected to be submitted to the Supreme Court for approval. The feasibility of cloud seeding depends on the presence of clouds or moisture in the atmosphere, which experts anticipate around November 20-21.

Cloud seeding involves dispersing substances like silver iodide or dry ice into the air to enhance condensation and precipitation. This technique has been employed worldwide, particularly in regions grappling with water scarcity or drought conditions. While India has undertaken some cloud seeding endeavours, significant progress remains elusive.

The effectiveness and environmental impact of cloud seeding are still being investigated. The combination of unfavourable meteorological conditions, local pollution sources like vehicle emissions and paddy straw burning, and stubble burning in neighbouring states contribute to Delhi’s hazardous air quality during the winter months. Delhi’s peak pollution season typically runs from November 1 to 15, coinciding with the increased prevalence of stubble burning in Punjab and Haryana.

Over the past two weeks, the air quality in Delhi-NCR has deteriorated due to declining temperatures, calm winds that trap pollutants, and an escalation in paddy straw burning. According to a study by the Energy Policy Institute at the University of Chicago, Delhi’s air pollution levels are among the worst in the world, potentially reducing life expectancy by nearly 12 years.

The Delhi government’s cloud seeding initiative is a potential strategy to combat air pollution, but its effectiveness and environmental implications require further research and evaluation.
