Miniature urban forests are being touted as a way to rewild our cities and make them more sustainable. The Tiny Forest scheme has created more than 250 plots in places like business parks and schools in the Netherlands.
The scheme can provide a cooling effect in nearby streets, according to a study by the Not-for-profit Institute for Environmental Education IVN.
Other people are looking to bring greenery into city centers. Designer Thomas Heatherwick has designed designs for a new green heart for the city of Nottingham, England, shown in this rendering.
It is described as a blueprint for sustainable city centers in a post-Covid world that would bring a hectare of new green space and additional wildlife habitat to the wider area.
Singapore has been a proponent of green corridors for a long time. These high-tech supertrees are surrounded by an oasis of urban greenery.
Local authorities and activists have introduced beavers to the city for the first time in a long time.
Rewilding can restore ecosystems and grow the range and abundance of different species in an area, but it also has a wider-reaching role in making cities greener, healthier and more resilient to the impacts of climate change, says Shirley Rodrigues, London's deputy mayor for the environment.
