Earth Day is this week, on Wednesday, April 22. From my vantage point, two of the most impactful forces shaping the health of our planet are converging—the climate crisis and urbanization—and it’s up to us whether it’ll be a cataclysmic collision or a chance to collaborate on change.

We’ve just lived through the three hottest years ever on record: 2023, ‘24, and ‘25. Ocean temps were higher than ever last year. And the global population is not only growing but getting more dense: According to United Nations data, close to 70 percent of the world’s population will live in cities by 2030.

What does this mean? In my view, this cements the power—and the responsibility!—of local food and ag systems to lead the charge toward more sustainability and climate resilience on a global scale.

“With bold investments and good planning and design, cities offer immense opportunities to slash greenhouse gas emissions, adapt to the effects of climate change, and sustainably support urban populations,” says António Guterres, Secretary-General of the U.N.

Through efforts like the Milan Urban Food Policy Pact (MUFPP)—signed by more than 330 cities worldwide—local leaders can share knowledge and experiences in strengthening equitable food systems. Earlier this year, I had the honor of emceeing a MUFPP Regional Forum, and the collective food system power we have in each of our communities is electric and unbelievably inspiring.

Already, so many municipalities and local governments and advocates are stepping up to the plate, which is amazing to see and learn from. This Earth Day, I want to highlight some success stories that are turning cities into sites of big-picture transformation:

On the subject of procurement: Last year, Seoul, South Korea launched a new Climate-Friendly Meal Service initiative to expand nutrition education for students and improve the sustainability of food grown for the country’s universal school meals.

“Because school meals are universal and publicly funded, they embody social equity, while simultaneously shaping demand for eco-friendly and local agricultural products,” says Seulgi Son, a Postdoctoral Research Fellow at Yonsei University.
