International Day of the Forest 2018: Forests and Sustainable Cities
In 2018, the International Day of Forests (IDF) will address the theme, ‘Forests and sustainable cities,’ and will focus on how forests and trees in urban areas regulate temperature and water flows, provide nutritious foods and shelter, cleanse the air and foster community cohesion and individual well-being, among other benefits.
The UN General Assembly proclaimed 21 March the International Day of Forests in 2012. The Day celebrates and raises awareness of the importance of all types of forests. On each International Day of Forests, countries are encouraged to undertake local, national and international efforts to organize activities involving forests and trees, such as tree planting campaigns. The theme for each International Day of Forests is chosen by the Collaborative Partnership on Forests.
Forests and trees store carbon, which helps mitigate the impacts of climate change in and around urban areas.
Trees also improve the local climate, helping to save energy used for heating by 20-50 percent.
Strategic placement of trees in urban areas can cool the air by up to 8 degrees Celsius, reducing air conditioning needs by 30 percent.
Urban trees are excellent air filters, removing harmful pollutants in the air and fine particulates.
Trees reduce noise pollution, as they shield homes from nearby roads and industrial areas.
Local populations use the fruits, nuts, leaves and insects found in urban trees to produce food and medicines for use in the home, or as a source of income.
Wood fuel sourced from urban trees and planted forests on the outskirts of cities provides renewable energy for cooking and heating, which reduces pressures on natural forests and our reliance on fossil fuels.
Forests in and around urban areas help to filter and regulate water, contributing to high-quality freshwater supplies for hundreds of millions of people. Forests also protect watersheds and prevent flooding as they store water in their branches and soil.
Well-managed forests and trees in and around cities provide habitats, food and protection for many plants and animals, helping to maintain and increase biodiversity.
Forests in cities and surrounding areas generate tourism, create tens of thousands of jobs and encourage city beautification schemes, building dynamic, energetic and prosperous green economies.
Urban green spaces, including forests, encourage active and healthy lifestyles, improve mental health, prevent disease, and provide a place for people to socialize.
