Last Sunday, the Uttar Pradesh government suspended Durga Shakti Nagpal, the sub-divisional magistrate of Gautam Buddh Nagar who had been cracking down on the sand mafia. Three days later, Pale Ram Chauhan, a Noida-based activist who had taken on the local sand mining mafia, was killed. Sand mining is back under the scanner. As are questions on how to balance the construction sector’s need for sand with ecological and social concerns. For, right now, what is underway in construction boom-spots such as Greater Noida and elsewhere is analogous with nothing less than Karnataka’s iron ore scam.
