Green fighting climate change

Green trees and plants will prevent atmospheric damage, both on a global and on a local scale. Climate change will cause extreme heat and drought, alternated with excessive rainfall. This will make high demands on the urban environment. Trees and plants in a city can provide a cooling effect in case of a heat wave.

In the case of extreme rainfall, a planted soil will have a better water storage capacity than asphalt and concrete. It has been suggested that cities could prevent flooding by constructing so-called ‘wadis’. These planted areas, situated below surface level, can be temporarily flooded during excessive rainfall, preventing overloaded sewers. But public green places, like parks and gardens, contribute to a healthy urban climate as well.

Citizens themselves also play a role in fighting climate problems with having an unpaved and green front- and back garden. People without a garden can also contribute to a green environment. They can opt for ‘green roofs’ or by having a ‘pavement garden patch’: you lift out some paving in front of their houses and replace these with plants. Some cities even encourage such citizen initiatives by granting subsidies.
