Miniature urban forests are being touted as a way to rewild our cities and make them more sustainable. In the Netherlands, the Tiny Forest scheme has established more than 250 plots at places like business parks and schools.

The Tiny Forest scheme is led by the not-for-profit Institute for Environmental Education (IVN). Researchers have found that the scheme can provide a cooling effect in nearby streets.

Others are also looking to bring greenery into city centers. Designer Thomas Heatherwick has created designs for a "new green heart" for the city of Nottingham, England, shown in this rendering.

It is described as "as a blueprint for sustainable city centers in a post-Covid world" that would deliver a hectare of new green space and additional wildlife habitat in the wider area.

A derelict shopping mall would become a flexible green space to bring people together.

Singapore has long been a proponent of green corridors. These high-tech "Supertrees" are surrounded by an oasis of urban greenery.

The London Rewilding Task Force is supporting numerous schemes to encourage wildlife, including developing new woodlands.

Elsewhere in London, local authorities and activists have reintroduced beavers to the city for the first time in centuries.

"We know that rewilding can restore ecosystems and grow the range and abundance of different species in an area, but it also has a much 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.
