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.
New York City is prioritizing plant-based meals in public institutions such as schools, where students participate in Meatless Mondays and have “plant-powered” options, and hospitals, where vegetarian options are default. In just the first year of this transition, the city reported a 36 percent reduction in carbon emissions!
When it comes to fighting food waste: Milan, Italy, has launched an award-winning food waste hub model to help the country halve food waste by 2030 by facilitating food recovery and distribution, and each of five hubs within the model have recovered the equivalent of over 260,000 meals per year.
Or, take Baltimore, where the Baltimore Zero Waste Coalition is dedicated to promoting waste diversion practices that minimize landfill or incineration use and maximize recovery work through education, collaboration, and advocacy. Meanwhile, the city is also focusing on better managing the waste that does occur. The city’s Department of Public Works adopted a 10-Year Solid Waste Management Plan in 2024, aimed at increasing organics recycling and promoting backyard and community composting.
And cities can also vitally support farmers and food production: In Brazil, São Paulo’s Connect the Dots program brings together urban buyers for organic produce, helps train the family farms growing those crops in more sustainable practices, and safeguards farms and forests from urban development.
In Xochimilco, in Mexico City, researchers, farmers, and government entities have partnered to create a sustainable certification program that has helped to restore 40+ floating farms, protect endangered axolotls, and connect producers to premium markets while improving local livelihoods.
And across the world in Kenya, we’re seeing action on the county level, too. Several Kenyan counties have adopted policies to expand agroecological production and help farmers access markets.
As U.N. Habitat analysts write, “While the overlapping challenges of environmental stress and rapid urbanization are uniquely daunting, it is precisely this intersection that makes urban climate action so opportune.”
If cities or other local governments where you live are taking bold action on food systems and climate, share their stories. And if your city is not doing its part, then it’s time for us as citizen eaters to use Earth Day as an opportunity to push for change! Reach out to your local elected officials and community advocates this week to share these success stories from other cities. And do reach out to me via email too, to let me know how Food Tank can use our resources to help.
