In a bid to balance the environment with development, Delhi Chief Minister Arvind Kejriwal announced on Monday that no manufacturing units will be allowed in new industrial areas of the city and these zones would be available only to services and hi-tech industries. The move will also boost Delhi’s economy, besides helping the city become a hub of hi-tech and service industries which include IT-enabled services, call centres, software and hardware sector, and media programme production as they will now be provided land at cheaper rates by authorities in industrial areas.
