Karnataka is one of the leading states to witness the devastating effects of rampant sand mining. Between 2015 and 2018, the state has officially registered 20,779 cases of illegal sand mining, and 9,599 FIRs.
The state govt is receiving approximately Rs 150 crore per year as royalty from legitimate sand mining. As per estimates, the state govt is losing around Rs 200 crore per year due to illegal sand mining.
According to cement manufacturing companies’ data, around 18 million tonnes (MT) of cement is sold in the state every year. The cement-sand mix ratio is either 1:4 or 1:6 (four or six bags of sand per cement bag). Even if 1:4 ratio is taken, 72 MT of sand is approximately used in the state every year.
The official data from the Department of Mines and Geology shows that from the blocks permitted by it, a total quantity of 30 MT of sand (from all types of blocks – river sand, patta land, blocks allocated to govt departments, and manufactured sand) is produced in the state. Thus, there is a difference of at least 42 MT sand compared to the cement sold in the state.
