Beginning to End Hunger presents the story of Belo Horizonte, home to 2.5 million people and one of the world's most successful city food security programs. Since its Municipal Secretariat for Food Security was founded in 1993, malnutrition in Belo Horizonte has declined dramatically, allowing it to serve as an inspiration for Brazil's renowned Zero Hunger programs. The Municipal Secretariat's work with local small family farmers also offers a glimpse of how food security, rural livelihoods, and healthy ecosystems can be supported together. While inevitably imperfect, Belo Horizonte offers a vision of the path away from food system dysfunction, unsustainability, and hunger. The author's case study shows the vital importance of holistic approaches to food security, offers ideas on how to design successful policies to end hunger, and lays out strategies for how to make policy change happen. With these tools, we can take the next steps towards achieving similar reductions in hunger and food insecurity elsewhere in the developed and developing worlds.
