Climateways concept for green infrastructure
Concrete, asphalt, rails, glass – grey infrastructure can be found everywhere in cities. But green spaces, trees, green roofs and the like are severely limited in their area. Until now, urban vegetation has often been used for optics, but not as one of the most important means of climate adaptation.
City - Nature
City – Nature Due to a low proportion of vegetation in the city, the streets heat up, the air quality deteriorates and the risk of flooding increases. The plants that were planted in the city live in an environment that is foreign to them, in which they are exposed to a variety of vitality-inhibiting factors and cannot be adequately supplied. Not only the structural but also the climatic conditions make optimal growth difficult. Advantages from the vegetation are therefore absent.
Lack of water cycle
Trees evaporate an average of 200 litres of water per day and can significantly reduce the ambient temperature with the help of the resulting evaporative cooling. However, in order for this process to work, the tree must also be provided with this large amount of water. However, since more intense dry phases occur more frequently and water can rarely seep away or be stored so far, there is a lack of water to supply the plants. Instead, these must be artificially irrigated with valuable drinking water. As a result, there is currently no natural water cycle in cities, causing not only higher temperatures, but also higher costs.
