Global Mayors’ Forum on Climate Adaptation

On demand on CAS TV – from the Netherlands

Every day, cities are dealing with the effects of climate change and the need to adapt to be resilient. It is the task as city leaders to address these issues and generate solutions. With the Joint Statement on Accelerating Climate Adaptation in Cities, Mayors underline the ambitions and needs to speed up and scale up adaptation measures in 1000 cities in the coming decade.

The impact of the COVID-19 pandemic on cities and communities is enormous. But as city leaders address the virus and the economic fallout, they also have a responsibility to prepare for the future. At the Climate Adaptation Summit 2021, the Mayors’ Forum focuses on the need for climate action and more concrete adaptation in cities.

The 8th Secretary-General of the United Nations and Chair of the GCA, Ban Ki-moon opens the Forum. It showcases the challenges and solutions cities face, featuring the mayors of such influential cities as Miami, Paris, Accra, Christchurch, Milan, Jakarta, Surat, Beira, Antwerp, Greater Manchester, Tirana, Athens, Khulna, Istanbul, and Rotterdam.

1000 Cities Adapt Now

These mayors and a new coalition of partners present a 10-year global program to accelerate and scale adaptation measures in cities. ‘1000 Cities Adapt Now’ (1000CAN) is a global program that aims for a green and just post-COVID-19 recovery — a recovery that helps create new jobs, improve equity and prepare communities to adapt to climate and health threats.

The coalition network partners seek commitment of other mayors to strengthen the role of cities in improving our environment, climate and society at CAS 2021, in the lead-up to COP26, and beyond.

The 1000CAN global programme is initiated by a new coalition between the Global Center on Adaptation, the World Resources Institute, Resilient Cities Network and UN-Habitat. They join forces to speed up adaptation within cities and scale up to 1000 cities during the coming decade. It consists of a comprehensive offer focusing on transformative capacity building in cities and peer to peer learning between cities.
