Earlier, the govt. land rates were a fraction of market rates. During boom of late 90d ans 00s, a large number of land dealings and registration gave tremendous revenues to state govts. In an effort to maximise this revenue, official rates of land has been jacked up by the State Govts to such an extent that they are higher than the actual market price. As a result the number of land dealings have drastically reduced and so is the revenue to the state govts. (Similar case to to Flexi-fare scheme). To day nobody want to buy and register and land in pockets where official price is much higher than market price, unless absolutely essential.
As a result the new infrastructure projects are...
