The Indian Cloud-seeding Project Seeks to Eliminate Pollution by Producing Rain

In an attempt to induce rain and lessen pollution, Indian scientists intend to add materials to clouds above the nation’s capital, New Delhi. The process of creating rain artificially is known as cloud seeding. In order to make rain, several chemicals are added to clouds. Raindrops have the ability to cling to pollution particles and carry them to the earth with them. According to ratings, New Delhi is the city with the greatest air pollution worldwide. According to reports, the issue has gotten worse recently around the city.

Every year, the city’s air quality deteriorates before winter arrives. Cold air can trap a variety of pollutants during this time, such as industrial, building, car, and agricultural emissions. Around November 20, scientists predict some clouds to pass over the city. When the clouds are sprayed with a salt solution, they hope that it will cause a lot of rain. Scientist Manindra Agrawal of the Indian Institute of Technology in Kanpur, the country’s capital, is spearheading the research. He informed the Reuters news agency that silver iodine will be added to the salt combination to aid with precipitation. It’s supposed to be sprayed throughout an area of 100 square kilometers on clouds. The project will cost roughly $120,000, according to Agrawal.

In order to reduce pollution, the 20 million-person metropolis of New Delhi’s municipal administration has already suspended schools, halted construction, and announced plans to impose limits on car use. On November 9, the city’s air quality index stood at 506 points. The Swiss company IQAir, which bills itself as a provider of “air quality solutions,” rates this level as “hazardous”. The chief of SAFAR, the Indian government’s air quality measurement organization, is Gufran Beig. According to him, Reuters, the city needs a lot of rain to remove the toxins. Beig continued, saying that a little rain may make things worse.

According to the head of SAFAR, Delhi is currently receiving smoke from crop burning in the states of Punjab and Haryana. The sources of pollution in the city are increased by this smoke. “Therefore, this chain of transport from Punjab to Delhi will not be broken unless a huge pressure is established by intense rain,” Beig stated. According to a recent government declaration, stubble burning in Punjab and Haryana is responsible for almost 38% of the pollution in the city. Stubble burning is a practice used by farmers to remove material leftover from rice harvests so they may sow other crops. The statement also stated that Indian officials instructed leaders in both states to “take effective actions” to identify and restrict stubble burning.

According to Reuters, New Delhi officials are asking the Supreme Court to approve the project. Cloud seeding has been employed in a number of nations to try and bring about rain, enhance air quality, and irrigate crops during periods of severe drought. Mexico, the US, China, Indonesia, and Malaysia are a few of these.
