In our rapidly urbanizing world, the fate of biodiversity rests heavily on the shoulders of cities. Urban areas occupy less than 1% of the Earth's landmass, yet they accommodate more than half of the global population.

The relentless march of urbanization has not been without consequences for the natural world, with direct repercussions on the well-being of urban residents. Understanding the significance of nature in cities and recognizing the multi-benefits it provides is crucial.

To support urban ecosystem restoration the United Nations Environment Programme (UNEP) has handpicked 19 cities to take part in the Generation Restoration project to be announced on World Cities Day. This initiative stands as a contribution to the UN Decade on Ecosystem Restoration and the Global Biodiversity Framework.

Of these, eight cities are set to embark on innovative Pilot projects to restore their urban ecosystems, and 11 Role Models are set to accompany and support them as Champions of Restoration. UNEP and ICLEI are providing financial and technical assistance to these initiatives to ensure their success.

The Generation Restoration cities are embracing Nature-based Solutions (NbS) to restore the essential bond between cities and nature, all the while mitigating the adverse effects of climate change on urban communities.

Mirey Atallah, Head, Nature for Climate Branch, Ecosystems Division, UNEP, celebrated this initiative: "Embracing nature-based solutions in our urban landscapes is a commitment to a greener, more sustainable future for both citizens and the urban areas they occupy. Generation Restoration is the guiding light for cities as they endeavor to harmonize with nature, constructing resilient and thriving communities that coexist harmoniously with the environment."
