India's capital city, Delhi, is set to become a testing ground for an ambitious experiment aimed at cleansing its notorious smog. The Indian government has embarked on a cloud-seeding initiative, designed to induce artificial rain and subsequently improve air quality in the world's most polluted metropolis.
Under the plan, aircraft or drones will be used to disperse silver iodide particles into clouds, which will then supposedly trigger precipitation and reduce pollution levels. Months of unseasonable weather have hindered progress on this project, but after Diwali festivities further exacerbated Delhi's toxic air, officials have now initiated the trial.
According to experts, however, cloud seeding is not a panacea for solving India's air pollution woes. Proponents claim that the method can produce more frequent and intense rain showers than natural clouds would, but critics argue this effect may be negligible and rely on cloud conditions, which are often scarce in Delhi during peak winter months.
Furthermore, proponents of the plan have been accused of applying science to a flawed solution. Delhi's pollution is rooted in deeper issues such as agricultural burning, industrial emissions, and vehicle traffic, rather than being solely addressed by artificial precipitation. Two professors at the Centre for Atmospheric Sciences condemned the project as a "gimmick" citing the previous government's ineffectual "smog towers" initiative.
Additionally, there is little research into the long-term effects of repeated use of cloud seeding chemicals on agriculture and human health. Critics warn that attempting to solve India's air pollution crisis with such short-sighted solutions will only perpetuate a cycle of ineffective policies and environmental degradation.
