Delhi’s Rs 1 Crore Cloud Seeding Fails to Produce Rain
The Delhi government’s ambitious cloud seeding project has failed to produce any measurable rainfall despite spending over Rs 1 crore on three separate trials conducted with IIT Kanpur.
Key Takeaways
- Three cloud seeding attempts in October failed completely
- Rs 1.07 crore already spent with zero results
- Full implementation could cost Rs 25-30 crore
- Experts question scientific validity and cost-effectiveness
Trials conducted on October 23 and 28 brought no rainfall as humidity levels of 10-15% fell far below the 50-60% required for successful cloud seeding. IIT Kanpur estimates that full-scale implementation throughout winter could cost Rs 25-30 crore.
Why Cloud Seeding Failed in Delhi
Experts identified insufficient moisture in winter clouds as the primary reason for failure. Delhi’s winter climate is typically too dry for cloud seeding to work effectively, with most rain coming from rare western disturbances rather than artificial induction.
Massive Costs Involved
Each cloud seeding trial costs approximately Rs 35-40 lakh, with the government having already spent Rs 1.07 crore on three unsuccessful attempts. The project requires:
- Specialized aircraft (currently unavailable in India)
- Silver iodide flares and expensive instruments
- Over Rs 5 crore in equipment costs alone
- Additional expenses for maintenance and logistics
Questionable Track Record
Cloud seeding has shown limited success globally and lacks strong scientific validation. Previous attempts in Delhi during 1957 and 1972, along with Andhra Pradesh’s efforts between 2004-2009, yielded poor results despite significant spending.
Expert Criticism and Alternatives
Environmentalists have labeled the project an “expensive spectacle” that offers only 1-2 days of pollution relief at best. Former officials and scientists argue that scientific protocols, not political optics, should guide such decisions.
Experts emphasize that artificial rain cannot substitute for tackling root causes of pollution: , vehicular emissions, industrial pollution, and construction dust. Real progress requires sustained, structural measures rather than costly experiments.
