Given that Bengalururov’s once slight climate, which is becoming more and more, continues to be in the news, a newly published study shows that the area of 15.41 km. Km in the city has a very high temperature, although soil use evaluated by data on time long -distance survey from 1973 to 87% in 1973 to 87% in 1973.
Only 168.93 square kilometers were in favorable conditions according to the index of the urban thermal field (UTFVI), which evaluates the well -being of the environment on the ecological thermal comfort of considering the effect of the city thermal island (UHI), while 545.25 km. KM was under indirect environmental conditions.
The UHI archipelago, representing the combined effect of more localized thermal islands, which forms a wider area of elevated temperatures, was observed mainly in the eastern and northern parts of the city, the study added.
The details of the ambient air
“Temporary details of the ambient air temperature have been met from Indian monitoring stations of the Meteorological Department in Bengalur, revealing that the ambient temperature showed a growing trend with a change in the landscape structure with an increase in paved surfaces (buildings, roads, etc.) and a decrease in natural porous surfaces (vegetation, lakes, etc.). It can temperatures from 16 ° C to 18 ° C at the age of 70, 19 ° C in the 90s, 21 ° C in 2000, 28 ° C in 2010 and 34 ° C in 2025, he added.
These findings coincide with comparing daily maximum temperatures from 2015 to 2024 against the standard standard of the meteorological organization of the World Meteorological Organization in 1991–2020, which showed that traditionally colder cities such as Bengaluru and Mumbai have experienced over average temperatures than Delhi.
The study “Urban Heat Island is connected with the landscape morphology” was conducted by TV Ramacandra, Rajesh Singh Rana, S. Vinay and Bharath H. Aithal and published in Nature and Country Studies, which was introduced in the fact that the city was mentioned in the city. 20. And analyzes. The main planning official responded positively to the integration of the research outcome in the proposed revised main plan 2031.
Bengaluru’s growth story
According to scientists, Bengalur witnessed spatial expansion in the mid -1920s by founding Bruhhat Bengalur Mahanagar Palike by including neighboring rural landscapes, which led to the transformation of agricultural land into paved areas.
“The urban landscape witnessed a 1,078% increase in a decrease of 88% of vegetation coverage and 79% of the water body, leading to the transition of the landscape from porous to paved surfaces, which affects hydrology, ecology and socio-economic aspects. The second aspects founded by 1%, which is in 1973, a 1% -national growth.
He added that after 2002, Era witnessed an annual growth rate of 2.01% due to the spread of private industries and special economic zones (seas). This development generated job opportunities and promoted rapid conversion of suburban landscapes for residential and commercial development. The 2012–2021 period was characterized by intensive urban growth in the powered IT sector and the related inflow of the population and the annual urbanization reached 3%, he said that after 2021 the annual urbanization was 0.5% with proliferation of residential layout and sliding lower density over BBMP.
Political recommendations
Prof. Ramacandra from the Indian Institute of Science, Who Is One of the AuthorS of the Study, Said Policy Recommintendations to Mitigate Uhis in Cities Should Include Increasing and Protecting Green Spaces, Integrating Green Infrastructure into Urban Development Plans MODERATE LOCAL TEMPERATURE, MAINTAINING 30% OPEN SPACES WITH GREEN COVER AT POBE Levels, Connecting Fragmented Tree Patches for Promotion of Ecosystem Health and Sustainability, Rejuvenation 216 lakes to maintain rainwater and facilitate, among other things
