Large scale deforestation can cause 18% monsoon fall in India, destroy farming

Land mafia seems to be having a field day across the country. cutting of trees is becoming the norms. Jungles are fast disappearing and malls, factories are being built on their place. But many a times whole jungles are cut merely to sell off the land to housing companies or for special economic zone.

But this is not just diminishing the green cover across the country, it is going to have long term repercussions on monsoon too. India may become a barren land if this mindless deforestation is not stopped immediately.

A study claims that if the same level of deforestation continues for a few more years, it will cause monsoon rains to shift south, cutting rainfall in India by as much as by a fifth.

Scientists claims that while releasing carbon dioxide into the atmosphere, deforestation also causes changes in how much light reflects off the earth’s surface and the amount of moisture in the atmosphere from plants transpiring.

The latest study was conducted by researchers associated with the Indian Institute of Science in Bangalore. In a statement researchers said, “We wanted to get a basic understanding of the effects of large-scale deforestation at different locations on monsoon rainfall…Our study is showing that remote deforestation in mid- and high-latitudes can have a much larger effect on tropical rainfall than local tropical deforestation”.

Scientists working with India’s top scientific research institute claim that the South Asian monsoon region would be affected the most, with an 18 percent decline in precipitation over India, the scientists wrote in the paper published in the Proceedings of the National Academy of Sciences (PNAS). The authors said that evaluations of the climate benefits of planting trees on bare or cultivated land or in deforested areas must include remote impacts such as rainfall. The study noted that land used for crops and pastures has increased globally from 620 million hectares in the 1700s – or about 7 percent of the global land surface – to 4,690 million hectares in 2000, about a third of the world’s land surface.
