Delhi Prepares for Artificial Rain via Cloud Seeding to Combat Pollution
Delhi is set to conduct cloud seeding between October 28 and 30 to induce artificial rain aimed at reducing severe air pollution by washing away particulate matter. IIT Kanpur leads the project, which uses silver iodide particles to stimulate rainfall. While considered relatively safe in low quantities, concerns remain around health effects for vulnerable populations and possible environmental impacts from chemical accumulation.
Delhi has finalized preparations for a cloud seeding operation intended to generate artificial rain to temporarily alleviate severe air pollution by settling airborne dust and particulate matter. The experiment, led by IIT Kanpur, uses a technique involving dispersal of silver iodide or salt particles into clouds to encourage water droplet formation and rainfall. The operation awaits suitable weather conditions, with a successful test recently conducted in Burari. Although silver iodide is used in small quantities and deemed relatively safe, health experts warn of potential respiratory, skin, and eye irritation particularly in individuals with pre-existing lung conditions. Environmental concerns also exist due to possible chemical accumulation in soil and water from repeated seeding, which could affect crops, aquatic ecosystems, and soil bacteria. Past studies indicate that typical use results in very low environmental impact, but ongoing monitoring is necessary. Cloud seeding is viewed as a short-term measure, not a substitute for sustained pollution control efforts such as reducing vehicular emissions and industrial pollutants. The initiative reflects a pioneering effort by India to employ weather modification for pollution management, with outcomes dependent on favorable atmospheric conditions during the planned window from October 28 to 30.
