Drought

Can floods lead to drought? After the flood, severe drought looming over Kerala

Guest blog by: Madhusoodhanan C.G. and Sreeja K.G

The state of Kerala experienced extreme precipitation events during the 2018 South West monsoon period with multiple episodes culminating in devastating floods across the state during 14th-18th August 2018. This year, with an early onset of monsoons that dovetailed with strong summer showers, the state received about 41% excess rainfall (2394 mm against the normal of 1700 mm) during the period June 1st to August 22nd [1]. Almost all of its reservoirs were near full storage by mid-July.

The heavy downpour and the uncontrolled opening of the spillway gates of almost all reservoirs that inundated huge stretches of river banks and floodplains, along with massive landslides across the Western Ghats affected more than 1.5 million people, with close to 500 human casualties, immense losses to property, livelihoods and resource security apart from the extensive damage to forests, wildlife and biodiversity. Maximum destruction was observed along the rivers of Periyar, Chalakudy and Pamba, all having multiple dams on their tributaries. The debate is still on as to the various reasons, both manmade and natural, behind the floods and the resultant wide-ranging casualties [2,3,4,5,6]. Meanwhile things have taken a rather unexpected turn in the flood ravaged state.

Sand Mining

Karnataka Sand Mining 2018: Hopeless, But Action Packed!

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.
