Circular cities of the world: what can green infrastructure do?
More than half of the world’s population currently lives in cities while projections show an increase to two thirds by 2050. Many people living in small areas means large amounts of waste, high resource consumption and loads of energy use. We can combat these issues with the ideas behind the circular economy.
If we were to envision our cities as circular cities, how would they look? Green. And why? Because achieving a circular economy means using nature as a template. With the help of green infrastructure, we can take nature as the example and transform our cities into circular cities.
Green infrastructure is a planned network of natural and semi-natural areas in urban areas strategically designed to solve problems with storm water management, heat stress, air quality and biodiversity, to name just a few examples. Urban trees, green roofs and facades and constructed wetlands are some common examples.
