Reason for the drying up of IT city Bangalore..!?
A severe shortage of drinking water is rampant in Bengaluru city, which has been unprecedented in the last 30 to 40 years. According to a study by the indian Institute of Science, this situation has occurred due to a 70 percent lack of rain in the city. It is well known that the concrete structure and pavement areas laid in Bangalore have seen a 1055 percent increase in the last few years. This is now the root cause of the depleting groundwater level across the city. It prevents rainwater from being absorbed into the urban area. From 2,324 hectares in 1973, the water spread has reduced to just 696 hectares in 2023. It has decreased by 70 percent, says a study by IISC's Center for Environmental Sciences. In 1973, Bengaluru's water area was 2,324 hectares. Over the past 50 years, careless concreting has caused the water table to shrink dramatically. Of the remaining water bodies, 98% are occupied by lakes, 90% of which are filled with untreated sewage or industrial waste. Naturally, this has also affected the recharge of the groundwater table, said Prof tv Ramachandra of IISC.
Bengaluru couple earning lakhs! In its study, indian Institute of Science scientists have mapped the change and evolution of Bengaluru over the past 50 years. Ramachandra said that groundwater resources across Bengaluru have been affected due to the depletion of the water table. The study shows that the city has lost its greenery due to high levels of air pollutants and rising temperatures. The 'concrete forest' has increased from 8 percent in 1973 to 93.3 percent in 2023. Bangalore's remote sensing data shows that only 1.5 million trees support Bangalore's population of 9.5 million. This means one tree for every seven people in the city. However, this is not even enough to sequester the 540-900 grams of respirable carbon per person per day, the professor said. Narrating the dire nature of the situation, karnataka Deputy chief minister DK Shivakumar said that such a drought has not been witnessed in the last 30-40 years. Shivakumar recently told reporters that despite droughts in the past, we have never reported such large taluks affected by drought. To address water scarcity, the Bengaluru Water Supply and Sewerage Board has taken various measures such as cleaning vehicles, constructing buildings and roads, and banning the use of drinking water for recreational purposes or decorations. It has also been announced that action will be taken against those digging borewells without permission within the city limits.
