What is Urban Heat Island: Urban Heat Island is the reason for the above-normal increase in temperature in some parts of the urban area as compared to the villages. Know, what is an urban heat island, why heat records are broken here and how can we control it?
Heat wave in many states of the country (Heat Wave) is going on. New summer records are being made. The mercury has crossed 49.1 degrees in Najafgarh, 48.1 in Gurgaon and 47.1 degrees in Noida. The surprising thing is that there was a lot of change in the temperature of the cities around Delhi. For example, the temperature in Noida, Gurgaon and Najafgarh (Temperature) It was high, but the temperature in the areas around them was less than this. There was a drop of about 2 to 3 degrees in this. Urban Heat Island is the reason for the above-normal increase in temperature in some parts of the urban area as compared to the villages. (Urban Heat Island) is.
What is an urban heat island, why do heat records break here and how can it be controlled? Know the answers to these questions
What is Urban Heat Island?
NASA According to the report, when the temperature in a city increases more than the surrounding rural area, it is called Urban Heat Island. This whole process is called the UHI effect. The main reason for this is human activities.
The most important role in any city becoming a heat island is its settlement. What is that city like, what are the buildings like there and how has it been designed. These things are the most important. The same factor is responsible for increasing the temperature in Delhi and surrounding areas and turning them into heat islands.
Why does a city become a heat island?
There are two main reasons for cities becoming heat islands. First, the structure of the buildings there. Second, the reduction of greenery and the occurrence of reservoirs. High rise concrete buildings, the heat emanating from the air conditioners installed in them, the increasing heat due to traffic in the cities. Not only this, the increasing use of glass and steel instead of brick in the building also helps in increasing the effect of heat. All these things together turn a city into a heat island.
Plants absorb carbon-di-oxide and work to reduce the temperature of the area, but due to urbanization, the number of trees is decreasing rapidly. Due to the increasing encroachment in the ponds, their scope is decreasing. As a result, the temperature is also making records at the same speed.
How will this heat decrease?
Such heat islands should not be formed in the cities, the biggest solution is to increase the number of greenery ie trees and plants all around. The temperature can be brought down by planting plants in open places. For this, terrace gardens and kitchen gardens can be made. White paint can be done on the floor of the roof. The effect of heat can be reduced by adopting many such methods.
Apart from this, promote the use of such things that reduce energy consumption. Use AC only when necessary. Where fans and coolers can work, use them only.
