Nairobi is a city of juxtapositions, informal iron sheet housing sits in the shadow of expensive apartment buildings, expensive SUVs slow down to let cows, goats and the occasional pig to cross the road and international supermarkets share a street with informal street-food vendors.
This bustling city is an example of rapidly urbanising areas across the globe where a dynamic food system is striving to feed a growing population. There are many challenges in the formation of sustainable, secure and safe food systems and the concept of One Health is a tool that can help us in our quest to solve them.
