Delhi Air Pollution: Can Cloud Seeding be the Solution?

Introduction: The Choking Grip of Air Pollution in Delhi-NCR

In recent times, the ominous cloak of air pollution has tightened its grip around Delhi-NCR, leaving residents gasping for breath. The hazardous air quality has prompted the Supreme Court to reprimand state governments for their apparent inability to tackle this crisis effectively. With no definitive solution in sight, individuals are now turning to nature, hoping for relief. Rain, once seen as a natural remedy, has given way to discussions about artificial rainfall in the Delhi-NCR region. But the question remains—can artificial rainfall truly be the game-changer? Let’s delve into the recent developments and explore the potential of cloud seeding as a means to combat air pollution.

IIT Kanpur’s Expertise Enters the Fray

The Delhi government, grappling with the severity of the situation, sought assistance from the Indian Institute of Technology, Kanpur (IIT-K). Known for its prowess in technology and innovation, IIT-K became a focal point in the battle against pollution. The Kejriwal-led government approached IIT-K, equipped with its aircraft fitted with flares for cloud seeding—a process approved by the Directorate General of Civil Aviation (DGCA). The collaboration aimed to explore the effectiveness of cloud seeding in curbing pollution.

Cloud Seeding: A Ray of Hope?

Understanding the Process

Cloud seeding involves the introduction of substances into clouds to stimulate precipitation, thereby reducing pollutants in the air. As water droplets form and fall, they carry dust particles away, purifying the atmosphere. However, the success of cloud seeding hinges on prompt action against pollution sources.

Collaboration with CII for Comprehensive Planning

IIT-K, in collaboration with the Confederation of Indian Industry (CII), has been meticulously planning cloud seeding operations for the past two months. This proactive approach involves coordination with both the Delhi and Central governments to ensure a cohesive strategy.

Temporary Relief with a Time Frame

While cloud seeding offers temporary relief, its effectiveness typically spans 7-10 days. During this period, the process helps in mitigating pollution, but long-term solutions necessitate addressing pollution at its source.

Challenges and Considerations

Geographical Implications

Covering an expansive area of over 1000 square kilometers, the Delhi-NCR region requires extensive cloud seeding efforts. However, the success of cloud seeding is contingent on the availability of clouds and their distribution, factors beyond human control.

Operational Costs and Maintenance

The aircraft used for cloud seeding incurs operational costs, including fuel and maintenance. Despite the associated expenses, the technique presents a feasible option for localized pollution control.

Dependence on Weather Patterns

Cloud seeding’s efficacy is heavily reliant on weather conditions. Identifying suitable cloud formations and choosing the right areas for seeding depend on unpredictable weather patterns.

Conclusion: A Short-Term Solution Amidst Ongoing Efforts

While cloud seeding offers a short-term solution to Delhi-NCR’s air pollution woes, it is crucial to acknowledge its limitations. Sustainable results demand a comprehensive approach, addressing pollution at its roots. As Delhi-NCR navigates through this environmental crisis, cloud seeding serves as a testament to human innovation, providing a breath of fresh air, albeit temporarily.
