Kolkata: The Kolkata Municipal Corporation (KMC) has started installing sprinklers to water trees that have been planted at various islands of Southern Avenue in South Kolkata. The sprinklers will be used twice a day for watering the plants.”We are using three to four sprinklers depending on the number of trees in each of the islands at Southern Avenue. They are controlled in such a manner so that the entire process is carried out scientifically. We have plans to install sprinklers at more places in the city, wherever feasible,” said Member, Mayor-in-Council (Parks & Gardens) Debasish Kumar. According to Kumar, the civic body has 12 vehicles that water plants on a daily basis in the city.

The civic body uses hydraulic ladders for trimming large trees. For Borough 1 to 10 of KMC, there is a hydraulic ladder in each for carrying out the trimming work. In Borough 10 to 16, KMC uses two such ladders for trimming.

It may be mentioned that soon after taking over as the Mayor of Kolkata a few months ago, Firhad Hakim has formed a separate department titled Urban Forestry and has laid a lot of emphasis on preserving and augmenting the green cover in the city. An expert committee has already been formed with Kumar as the chairman, which will soon come out with a comprehensive plan on how to move forward with urban forestry in the city. Apart from botanists of KMC, the committee has environment experts from Calcutta University and Jadavpur University as well as environment activists. It may be mentioned that in well-planned cities, especially in Europe, a minimum of 50 cubic feet of soil is provided for a tree’s root system to expand. However, in Kolkata, hardly 10 cubic feet of soil is available on an average for the same and therefore, toppling of trees during squalls and thunderstorms is becoming a common phenomenon every year, according to the environment experts.
