क्यों Kerala में आई है 94 सालों की सबसे भीषण बाढ़
At last count, 357 people lost their lives, and the floods destroyed roughly 906,400 hectares worth of crops. The cost to the state and its people stands at a staggering Rs 19,512 crore.For the state's oldest living generation, this was take two.The last rival to a flood of this scale and severity in Kerala was in 1924, where monsoons pelted the hapless state with 3,368 mm of rain. At the time, over 1,000 people are said to have lost their lives, not to mention an enormous toll on livestock.The 2,086 mm of rainfall this year is nowhere near as bad, but still 30 percent above the annual average. And the monsoon is far from over.Going beyond the weatherLeading experts suggest a heavy, artificial hand in this latest deluge.The state was forced to throw open the gates of 35 of its 39 dams, knowing full-well what was to come. Residents were forced to flee, on important roads that happened to be engulfed in floodwater and landslides.
The intensity of the rains meant that two dozen more dams in states nearby were forced to follow suit. The dam gates were opened and a torrent of hell was unleashed on God's own country.Reading the signsKerala was one of four other districts in the country with rains more severe than predicted in 2018. The rains saw a steady increase since 2015, culminating in the 'large excess' seen this year.Records from the India Meteorological Department from the start of the torrential rains in Kerala – between 9 August and 15 August – show a 255 percent departure from the norm in the state's hotspots.
Back in 2011, the Gadgil Committee put together a bunch of recommendations to the central government about ecologically-fragile regions in the Western Ghats. They found the highest number of vulnerable zones in Kerala and cited several reasons for them being classified as such.Some reasons for its vulnerability were geographical, a challenge posed by its position amidst the Ghats. Many other causes – quarrying, mining, illegal repurposing of forests, and high-rise building constructions – were man-made, controllable factors that the state chose to brush aside.“The flooding has definitely brought to light the existence of illegal stone quarries or a large number of unauthorised constructions on river beds,” Professor Madhav Gadgil said to PTI. "In this sense, it is definitely a man-made calamity where intense rainfall and human intervention have made it a serious disaster."The quarrying Prof Gadgil refers to, along with deforestation in the region, has intensified the horrific landslides the state is witnessing.
Were there early signs?One of the most severely affected areas is Ernakulum in Kochi, along the Periyar river, into which excess water from the Idamalayar dam was drained.Dam-safety expert N Sasidharan claimed that authorities waited till the water level in the Idamalayar reservoir reached its capacity of 169 feet, and had it been opened sooner, would likely have spared the massive evacuation efforts in the vicinity.MC Joseph of Kuttikkatt village near Eloor said that the authorities made a mistake by opening all four gates of the dam at once, flooding the underlying regions at a much faster rate than expected.“This is the result of poor planning by the disaster management authority,” Sasidharan added.
