But he said this is not the situation in Dhaka where urbanization has not taken into account protection of the environment.
"Global warming has adverse impact on temperature. Trees have played a significant role in cooling down this temperature. That is why we need to emphasize vegetation," Akther said.
Sustainable urban development requires a healthy living environment, Akther said, adding that "trees aside from its aesthetic function can also greatly improve the people's quality of life."
But Akther said that Dhaka authorities are busy providing structural facilities to city residents without considering the need for more green spaces.
"We have no designated corridors for reforestation. Roof- gardens may be a solution but a roof-garden is not suitable for big trees," Akther said. He suggested that the government use road median strips and footpaths for the planting of big trees.
A latest study shows that suspended particulate and ambient sulphur-dioxide levels in the city are about 4 times and 5 times respectively higher than the prescribed levels, owing to lack of vegetation in the city.
According to Akther, Dhaka's internal temperature has increased in alarming rate.In April 2012, the maximum temperature was recorded 41 degrees Celsius. The limited trees in the parks and streets in Dhaka are unable to help infiltrate and recharge required volume of rainwater underground.
"Increased temperature has a vast impact. Top soil is losing moisture rapidly. City's top soil is absorbing rain water before it goes to the underground water. So our underground water is not recharging with rain water due to high temperature," Akther explained.
