With a budget of ₹3.21 crore, the Delhi government teams up with IIT Kanpur to explore artificial rain as a short-term solution to reduce pollution levels in the capital.
In a major step toward battling air pollution, the Delhi government has greenlit five cloud seeding trials with a budget of ₹3.21 crore. The initiative aims to explore the potential of artificial rainfall to reduce toxic air levels in and around the national capital. Each trial is expected to cost approximately ₹55 lakh, totaling an estimated ₹2.75 crore for all five trials.
The first trial is scheduled between May and June, targeting an area of around 100 square kilometers, primarily on Delhi’s outskirts. The remaining trials will be conducted in phases, and their outcomes will be scientifically evaluated to determine effectiveness and environmental impact.
This innovative project will be executed by the Indian Institute of Technology (IIT) Kanpur, a premier engineering institute known for its expertise in environmental science and weather modification. IIT Kanpur will be responsible for all aspects of the operation, including aircraft deployment, chemical dispersal, scientific modelling, and logistical management.
The initiative marks a proactive attempt by the Delhi government to explore alternative methods for improving air quality—especially during periods when pollution levels surge due to factors like vehicular emissions, construction dust, and stubble burning in neighboring states.
Here are four things that you should know
Q1: What is cloud seeding?
Cloud seeding is a scientific weather modification process where substances like silver iodide or sodium chloride are dispersed into clouds to encourage artificial precipitation (rainfall). The method can help clear particulate matter from the air by bringing pollutants down to the ground.
Q2: How can cloud seeding help combat air pollution?
Rain generated through cloud seeding can wash away airborne pollutants, such as particulate matter (PM2.5 and PM10), dust, and chemical residues, resulting in cleaner and more breathable air. It acts as a temporary but immediate solution to reduce pollution levels.
Q3: What does it take to combat air pollution with cloud seeding?
Combating air pollution through cloud seeding requires:
- Suitable weather conditions, including moisture-bearing clouds.
- Advanced aircraft and equipment for chemical dispersal.
- Scientific expertise to monitor and model environmental impact.
- Continuous evaluation to ensure that the process is environmentally safe and cost-effective.
Q4: Is cloud seeding a permanent solution to air pollution?
No. Cloud seeding is a temporary intervention that can help reduce pollution during peak seasons. Long-term improvement requires a mix of policy reforms, green technologies, waste management, and emission control measures.
