Essentials with JD #429 **30 MILLION TREES BY 2027**


The City of Gwangju on Monday released its plan to  launch a project to create a Cool City, Gwangju by planting over 30 million trees.


The project will kick off from this year to 2027 so as to ease the urban heat island phenomenon and to create a cooler and greener environment.

Based on the plan, the City will plant 3 million trees every year for the next 10 years investing 390 billion won.

The City is set to enforce the project to expand greenery in the region based on its experience with its former 10 million tree planting project which was carried out between 2002 and 2017.


According to research, trees and vegetation lower surface and air temperatures by providing shade and through evapotranspiration. Shaded surfaces, for example, may be 20–45°F (11–25°C) cooler than the peak temperatures of unshaded materials. Evapotranspiration, alone or in combination with shading, can help reduce peak summer temperatures by 2–9°F (1–5°C).2,3

Trees and vegetation are most useful as a mitigation strategy when planted in strategic locations around buildings or to shade pavement in parking lots and on streets.
