Groundwater depletion cause
As per Prof TV Ramachandra of IISc’s Centre for Ecological Sciences, the water spread area has decreased drastically from 2,324 hectares in 1973 to only 696 hectares in 2023. This decline is believed to be the primary cause of the depleting groundwater table across Bengaluru.
Urban dynamics overview
The development of the Bangalore Information System (BuiS) and Bangalore Lakes Information System (BLIS) aims to provide a comprehensive overview of the Bengaluru's urban dynamics and ecological sensitivity, aiding researchers and policymakers in addressing these pressing issues.
Lakes encroachment
Encroachment on lakes, coupled with untreated sewage inflow, has further worsened the water crisis, with 98% of lakes affected.
Urbanization issues
Bengaluru's unplanned urbanization has led to various issues such as resource inequity, traffic congestion, and slum spread.
Vegetation loss alarmingly
The loss of 88% of vegetation over the past 50 years has severely impacted the sequestration of respiratory carbon.
Rising temperatures
Furthermore, an alarming 88% loss of vegetation has been recorded, exacerbating air pollution and rising temperatures.
Water spread decrease
Conversely, there has been a striking 79% decrease in the water spread area, leading to severe shortages and affecting groundwater levels.
Impact on landscape
The built-up areas in Bengaluru have seen a staggering 1055% rise over the past few decades, significantly impacting Bengaluru's landscape.
