Heavy rains in Bangalore have broken the records of the last several years. Heavy rains have caused flood situation in many areas of the city. It is obvious that this situation has arisen in Bangalore due to the heavy rains this time, but do you know that the situation is constantly changing due to climate change in the rains. Which the figures testify…
How much rain this time? – According to reports, in August this year, Bangalore received 370 mm of rain, which is only slightly less than the record of 387.1 mm of rain in August 1998. During September 1 to 5, some areas of Bengaluru have received 150 percent more rain than normal. While other areas like Mahadevapura, Bommanahalli and KR Puram witnessed 307 per cent more rainfall than normal.
Let us tell you that this rain in Bangalore is the highest in the last 32 years (1992-93). But, it is not that there has been heavy rain in Bangalore this year itself, for the last few years, heavy rains are coming in Bengaluru, which directly indicates climate change.
According to the Meteorological Department, the annual rainfall recorded in Bengaluru was 1,500 mm in 2021, 1,200 mm in 2020 and over 900 mm in 2019. Now in 2022, the situation is much worse. This suggests that the geographical conditions of Bengaluru are changing and the heavy rainfall is increasing every year.
At the same time, if we look at the decades, then after the decade of 1901-10, the decade of 2011-2020 has received the highest average rainfall. If we talk about heavy rains, then after the decade of 1921-30, the decade of 2011-2020 saw the fastest rain.
Apart from this, the expansion of the urban area of Bangalore is also a significant problem, as the urban area has increased by three times between 1992 and 2015, which is causing the depletion of agricultural land. In the last few years, 9 percent of the agricultural land, 2.4 percent of the forests have been lost.
