Karnataka Wants to Try Cloud Seeding Yet Again
Having seen a series of unsuccessful spells with cloud seeding in the past, the Karnataka Government is now planning to use the debatable weather modification technique to fight the drought, yet again. With cloud seeding having seen a record of mixed results, globally, will the exorbitant program emerge as a respite to the drought hit North Karnataka?
According to a report by the Times of India, Water resources minister B M Patil was quoted saying that the program would resume only if the Chief Minister Siddaramaiah agreed to the proposal.
What is Cloud Seeding?
A weather modification procedure, cloud seeding attempts to change the amount of precipitation that falls from the clouds, by dispensing substances into the air. Srinivas explains that there are two types of cloud seeding.
While the traditional form of seeding is heavier on the pockets, the rain-rockets too have their own constraints.
Around 50 such rockets would cost would cost about Rs 5,000, compared to the Rs 15 crore worth aeroplane driven seeding programs.
The weather predictions for certain parts of the city however, seem to forecast the likelihood of rains and thundershowers in the upcoming days. But the Karnataka government holds cloud seeding as a pivotal Plan B.
Being an elaborate 2-3 month project, cloud seeding requires the expertise of international agencies, coupled with the permission of the aeronautical department to study the nature of clouds and also the extent of the area.
Previous Attempts of Cloud Seeding
Cloud seeding and India go way back into the eighties, where the Tamil Nadu government first conducted the operations to tackle severe drought in the region. However Karnataka’s first encounter with the technique was met with little success.
The SM Krishna led Congress government in the state tried cloud seeding between 1999 and 2000, which was tagged unsuccessful, if not for a few spells of showers in North Karnataka, followed by 2 more experiments in the late 2000s.
He also urges the need for ‘radar-evaluation’, which would help estimate the moisture in the clouds.
The technique having seen mixed results, internationally, the man behind the rainwater club in Bangalore urges the need for a third party monitor in the state.
