Why has the Monsoon been so Heavy this Year?
Deforestation is one of the main reasons for this increased monsoon intensity. Evapotranspiration from the green cover of the Western Ghats is responsible for around 50% of the total rainfall received by southern peninsular India. Deforestation in these areas has contributed to Global Warming which has caused the monsoon intensity to increase steadily since the 1990s.
Human incursion and unscientific development in these ecologically sensitive areas have also been cited as reasons for this natural disaster. According to environmental scientists, this disaster could have been averted if the recommendations of the Gadgil committee had been implemented. Kerala and Karnataka were among the six states in the Western Ghats that unanimously opposed the recommendations.
