In the face of the climate crisis, cities across the world are emerging as integral problem-solvers in the development of an effective, multi-layered response. This webinar aims to discuss some of the most impactful and sustainable urban food safety and security actions. It will take the form of an online dialogue between city officials from New York City, Rio de Janeiro, and Milan and center on how cities design and manage their food policies. The discussion will be moderated by City Diplomacy Lab Director Lorenzo Kihlgren Grandi.

The webinar is the second in a series of three entitled “Cities and Climate Solutions.” The series celebrates the leadership of cities and provides inspiration for the thousands of cities and local governments around the world committed to shaping the global response to climate change.

Cities and Climate Solutions is a collaboration between the City Diplomacy Lab and Columbia Global Centers | Paris. This event is also co-sponsored by Columbia Global Centers | Rio de Janeiro.
