Answer: Rajasthan
Notes: Recently, Rajasthan launched India’s first drone-based artificial rain trial at Ramgarh Dam, shifting from aeroplane-assisted to unmanned aerial vehicles for cloud seeding. The project uses around 60 drones and is a joint effort between the state agriculture department and GenX AI (US and Bengaluru-based). It aims to revive the 129-year-old dam, which has been dry for 20 years. The project involves multi-department coordination with approval from the Directorate General of Civil Aviation (DGCA) for drone use. Cloud seeding uses particles like silver iodide to boost rainfall, with potential up to 20%, though results vary.
