5. Conclusion

The climate and biodiversity crises we are facing are not inevitable. They invite us to collectively rethink our lifestyles and the way our cities function and are designed. This observation comes at a time when many metropolises are already facing the negative effects of excessive mineralization, and public demand for nature to return to the city has never been stronger. The benefits of nature in the urban environment need no further demonstration, whether in terms of adaptation to climate change (water management, cooling), public health (air quality, supply of recreational areas) or support for numerous species whose abundance has declined sharply in recent years. These various observations once again support the need to renaturalize urban environments.
