In a decisive move to mitigate the growing threat of drought, the Karnataka government on Friday initiated a large-scale cloud seeding programme. The initiative aims to trigger rainfall in regions experiencing a severe deficit in monsoon precipitation, which threatens both agriculture and drinking water supplies.

The programme was officially flagged off at the HAL Airport in Bengaluru by the Water Resources Minister, N. Cheluvarayaswamy. To execute this high-tech operation, a specially equipped light aircraft will be utilized, with the total project cost estimated at ₹28.52 crore.

Why This Matters

BozokMedia analysis shows that the success of this mission is critical for the state's survival through the upcoming summer. With the southwest monsoon expected to conclude by the end of this month, the failure to store adequate water could lead to a catastrophic water scarcity crisis lasting until June of next year. This move highlights the increasing reliance on weather modification technologies due to erratic climate patterns.

While cloud seeding is not a guaranteed solution, it serves as a vital technological intervention when traditional monsoon patterns fail.

Addressing the challenges of the technology, Minister Cheluvarayaswamy candidly noted that previous cloud-seeding attempts yielded a success rate of only 35%. Despite these odds, the administration maintains that every effort to augment water availability is essential given the worsening drought conditions across the state.

Strategic Deployment and Technology

Unlike traditional disaster relief, this operation will not target specific districts in advance. Instead, a technical advisory and evaluation committee will monitor Doppler radar data every two hours. Aircraft will be deployed dynamically to areas where suitable cumulonimbus clouds are detected, specifically targeting rainfall-deficit zones and major reservoir catchments.

The scientific process involves dispersing chemical agents into clouds to induce precipitation. Depending on whether the clouds are warm or cold, substances such as silver iodide, potassium iodide, dry ice, and sodium chloride are sprayed to encourage moisture condensation into raindrops.

Historical Background

Cloud seeding has been used globally for decades to combat water shortages. In India, as climate change makes monsoon cycles increasingly unpredictable, state governments are increasingly looking toward atmospheric science to supplement natural rainfall patterns and protect their agrarian economies.
