One of the examples of this growing interest can be seen in the Milan Urban Food Policy Pact, which was initiated by the mayor of Milan, in Italy, on the occasion of the Milan Expo in 2015. This group of cities, which now counts 179 municipalities in the world, are committed to improve their food system at city and regional level. Some of these cities are taking innovative approaches, and the Pact facilitates the exchange of experiences across its members. The FAO has been supporting this effort through providing technical support, establishing a common indicator framework so that the cities can keep track of its progress. What has become very clear in this process is that situations in each of these cities are vastly different, and capacities varied. While this does not indicate that experiences from one city to another or a region to another cannot happen, it means that careful contextualisation is required when approaches, methods, or technologies are being introduced to a new city or region.

It has also highlighted the fact that while many municipalities are ultimately responsible for the food security of their citizens through decentralisation or devolution of power, capacity building in how a city deals with that has not been done, leaving them with little or no capacity to plan or implement appropriate policy at local level.
