cities greenIn 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."



Eight Pioneering Cities for Ecosystems Restoration

Out of an impressive pool of 250 applications from across the globe, eight cities have been chosen to receive grants of up to US$100,000 to fuel restoration projects.

In Cameroon, the city of Douala IV will breathe new life into mangroves and establish governance structures with active involvement from local communities. In Senegal, Dakar-Plateau and Thies are crafting a lush greenbelt and blue-green zones around the city, facilitating the movement of species between protected areas and controlling urban sprawl.

“The battle to protect the environment for our survival and that of the future generation is a lifetime battle that should be embraced by all. We are pleased to discover that our efforts have been recognized internationally”, stated Professor Moby Mpah, Mayor of Douala IV, Cameroon.

In the Philippines, Quezon City is rallying local communities and students to identify urban spaces in need of rejuvenation, transforming them into ecological corridors, green oases, and pollinator havens. Meanwhile, in India, the city of Kochi is undertaking the restoration of canals, once making up 70% of the city area, to reduce urban flooding and enhance the water quality of the Vembanad Lake ecosystem, with mobile wetlands and native mangroves.

Bangladesh's Sirajganj is unwavering in its mission to restore the city's riverbanks, creating a vibrant green corridor that promises rehabilitation, restoration, and the enhancement of biodiversity.
