Urban trees, which get valuefor their shade or because they give a touch of color to urban asphalt, are an essential element for the city. These can help mitigate some of the negative impacts of urbanization, and thus make cities more resistant to the changes.
Here are some ways that trees and urban parks contribute to making cities socioeconomically and environmentally more sustainable.
Improving air quality
A large tree can absorb up to 150 kg of CO2 per year, therefore they are of great importance in a city where pollution is usually a major problem. Trees can improve air quality, making cities healthier places to live.Visit this site for lawn care stanwood wa.
Absorbing destructive particles
In addition, large trees are excellent filters for urban pollutants and particles. They absorb polluting gases such as carbon monoxide, nitrogen oxides, ozone and sulfur oxides. They also filter fine particles such as dust, dirt or smoke from the air by trapping them on the leaves and bark.
Increasing urban biodiversity
Trees play an important role in increasing urban biodiversity, providing plants and animals with habitat, food and protection.
The strategic location of trees in cities can help cool the air between 2 and 8 degrees Celsius, thus reducing the effect of urban “heat island”, a build-up of heat by the huge mass of concrete, and other materials.
For mental and physical well-being
Research shows that living near urban green spaces and having access to them can improve physical and mental health, for example by lowering high blood pressure and stress. This, in turn, contributes to the well-being of urban communities.
Mature trees regulate water flow and play a key role in flood prevention and risk reduction of natural disasters. An evergreen or mature tree with a permanent green leaf, for example, can intercept more than 15,000 liters of water per year.
Proper placement of trees around buildings can reduce the need for air conditioning by 30 percent and reduce winter heating bills by 20 to 50 percent.
Trees can contribute to increasing local food and nutritional security by providing food such as fruits, nuts and leaves for both human consumptions. Its wood, in turn, can be used for cooking and heating.
Planning urban landscapes with trees can increase the value of a property by 20 percent and attract tourism and business.
