Visakhapatnam July 17: The district administration is yet to take up the cloud seeding project for the region though it has been cleared by the state government recently. Cloud seeding would be carried out in Raiwada region as per the government orders. In its order the state asked the collector to consult Prof. T. Sivaji Rao, director of Environmental studies, and his associates who had earlier carried cloud seeding successfully in the district. Prof. Sivaji Rao talking to this correspondent, said various departments and the industries should coordinate and hold a meeting to discuss the cloud seeding and the men and material needed. "I have asked the collector to convene a meeting with the heads of irrigation department, groundwater, Vuda, municipal corporation and the private and public sector undertakings which have been polluting the atmosphere. But there is no response from him so far. The ball is in his court. We are waiting keeping our fingers crossed,' Prof Sivaji Rao said. Blaming the industries, the professor said the factories were emanating pollutants causing heat effect on the clouds which were deflecting from the region. Similarly, the green cover on the hills was lost after Vuda allowed massive constructions on them during the last couple of years. Hence these departments should foot the bill for the cloud seeding project and assist the district administration to hasten the process. Several countries have been benefited from cloud seeding and among them China was the world leader, Prof Rao said. In China 37,000 technicians are employed to produce additional annual rainfall of 60 billion cubic metre or 1,750 thousand million cubic feet which is equivalent to the annual river flow in Krishna river. Australia is deriving 1:30 power and Honduras 1: 25, he added. Explaining the process, Prof. Sivaji Rao said common salt packets each weighing 150 grams would be shot into the warm clouds and silver iodide into the cold clouds by way of using mini rockets from hillocks. The experiments have been proved successful when conducted in 2002, he added.
