Delhi's Air Pollution Takes a Turn for the Worse, but Not Yet Safer with Cloud Seeding.
In an attempt to tackle its notorious pollution problem, India's capital has embarked on cloud seeding as a means to artificially induce rain. The Bharatiya Janata party government has harnessed this technology, which has been touted as a solution by some as a way to reduce Delhi's air quality, the most polluted city in the world.
The idea behind cloud seeding is that aircraft or drones disperse silver iodide particles into clouds, causing water droplets to cluster around them. This supposedly increases precipitation and cleanses the atmosphere. However, experts point out that this approach might not deliver as many results as claimed and often yields minimal outcomes.
Delhi's environment minister Manjinder Singh Sirsa recently stated that the first trial flight took place on Thursday with seeding flares launched into the sky. The city is set to experience its first artificial rain on October 29 if weather conditions remain favorable. However, experts are wary of cloud seeding being used as a panacea.
A recent statement by two professors at Delhi's Centre for Atmospheric Sciences highlights concerns about this approach. They labeled it a "gimmick" and criticized the idea, citing that there is limited research into long-term effects on agriculture and human health due to repeated use of chemicals like silver iodide or sodium chloride.
The experts also likened cloud seeding to previous government initiatives such as the construction of expensive smog towers, which failed to improve air quality. They urge caution, stating "snake-oil solutions will not clear the air in Delhi or the rest of North India."
Delhi has consistently ranked among the world's most polluted cities for over a decade. In 2024, pollution levels rose by 6% during winter due to emissions from crop burning, factories, and heavy traffic getting trapped over the city when temperatures drop.
While cloud seeding might seem like an innovative solution, it remains uncertain whether this technology will prove effective in significantly reducing Delhi's air pollution.
