If the figures are fed into a regular calculator, it will throw up an error message. The acres and acres of land lying idle and locked up for decades in industrial units, mostly public sector and, at times, private, add up to the size of a small country. So far no attempt has been made to evaluate its real worth. Now, the central government has finally embarked on a mammoth exercise: creating a databank for an estimated 10 lakh acres of surplus land held by 298 central public sector enterprises (CPSEs), including many closed units, spread across India. Even putting a bare minimum rate of Rs 25 lakh for an acre (which is absurdly low for cities like Mumbai or Bangalore), the worth of the government’s surplus landholding tots up over Rs 2.5 lakh crore, more than the notional loss in the 2G scam—or the famed hidden treasure of the Padmanabhaswamy temple in Thiruvananthapuram.
