‘Filling of several water bodies has had a telling effect’

BANGALORE: Rapid urbanisation is the reason for the drastic climate change that Bangalore has been experiencing over the last few years, according to Ramachandra, professor with the Indian Institute of Science (IISc.), Bangalore. Over the last three decades, the average temperature in the city has risen from 19 degrees Celsius to 26 degrees Celsius, Prof. Ramachandra noted.

He was speaking on “Environmental Consequences of Unplanned Urbanisation” at an interactive workshop organised by Karnataka State Road Transport Corporation (KSRTC) on the occasion of World Environment Day here on Friday.

Prof. Ramachandra said he conducted a detailed study on climate change in Bangalore between 1992 and 2006 using remote sensing data and the outcome showed that deforestation, disappearance of water bodies and increased carbon emission – all result of rapid urbanisation – have drastically changed the climate. With just 7.97 per cent urbanisation in 1973 and average temperature of around 19 degrees Celsius, Bangalore came to have 26 degrees Celsius average temperature when there was 45.19 per cent urbanisation. He said fast depletion of green cover and filling of several water bodies during the last three decades had a telling effect on the city environment. The number of water bodies too had drastically dwindled. From 53 water bodies, the numbers have come down to just 17 within the old city while the numbers came down from 207 to 93 in the Greater Bangalore during the last three decades. This had also resulted in drastic depletion of groundwater level, from 80 feet to 600 feet and in densely populated areas up to 1,200 feet.
