Constant increase in temperatures has been recorded in the month of March in Bangalore. As summer is not yet started the heat waves are reaching soaring highs and might go high in the upcoming days. Now we realized why bangalorean’s had been protesting for steel flyover and uprooting trees in the city. Bengaluru needs tree to give a better shape to the future generations.

Bengaluru, the “Air-conditioned city” with distinctive wet and dry climate seasons now feels high in all the major cities with above 35 degree Celsius for the past two years after a long decade. The citizens started taking measures to manage the aggressive heat. The reasons behind all these are “Urbanization”. It actually makes the city dry and taking away the purest environment from the citizens.

Due to the vast Urbanization measures trees have been uprooted, increase in air pollution, the increase in intensity of urban heat lands, loss of Biodiversity, pollution in river bodies, shrinking of lakes, Changes in Rainfall pattern, Low water levels in Reservoirs are considered as a serious danger to the future generations.

Uprooting Trees

Almost all the Indian urban cities has been polluted tremendously by air pollution and some of the cases recorded as deaths, in the recent years. Greenbelt is essential for an urban landscape delivering oxygen and evacuating carbon-di-oxide. Basically, trees help to reduce destructive air toxins like sulphur dioxide which are surrounded in the atmosphere.
Vijay Nishant, an urban conservationist and tree doctor said, “Bengaluru is mainly famous for its green cover and cool climate. I have never seen the temperature going up more than 23-degree Celsius during my childhood and even if it goes beyond rain would make possibly cool. Even though the soil is so fertile for the plantations the latest urbanization makes the city as a heated land and lost in vegetation”.

Urban Heat lands

In 2016 April, Bengaluru recorded the most sizzling hot temperature with 39.2 degree Celsius says “The New Indian Express”. Uprooting trees for developmental purposes in an urban landscape lead to a massive loss of the temperature control in cities like bengaluru. Especially during summer, the city encounters extreme warmness in roads and the air temperatures have a downfall of less than 3-5 degree Celsius in bengaluru.

Surendra Kumar, Director of Institute of Wood Science & Technology (IWST) said, “Trees are so critical for a microenvironment. Our college campus is fully surrounded by the trees and one can feel it very hot if he/she steps out of the campus”.

Loss of Biodiversity

Trees and lakes are the major habitat for birds. Due to the carelessness of the citizens lakes are being used as a dumping yard and industrial wastes creates frothing and foaming. Lakes are the golden gift for a city to maintain the healthy environment.

Salim khan, Research scholar, Madras University said, “The city's bigger infrastructure models like high rise apartments, Industrial units, IT constructions blocks the free flow of wind and that makes the city warmer. Adding to that the glass buildings reflect during day time resulting in high temperatures in the surroundings”.

Shrinking of lakes is one of the major drawbacks for the downfall of birds, but only very few places are attracted by the birds now. The lakes which are left by the nature also got affected by the people, and nobody takes it serious. The knowledge of using the water and maintaining the water culture is not clear with the people, he added.

The urban government bodies like the Bruhat Bengaluru Mahanagara Palike (BBMP), the Bangalore Development Authority (BDA), and Bangalore Metro Rail Corporation Ltd (BMRCL) have been cutting trees for the developmental activities by saying the concern departments will replace the cut down trees wherever necessary and there is no sign of new plantations happened elsewhere in the city from the past 10 years. There are no such records available in the government websites and in databases.

The greener ecosystem, the survival of biodiversity, the future generations to benefit the clean environment, easy and safest access to nature and greenery are to be considered and should be well protected by the people and the government bodies before planning for urbanization in a fast paced city.
