Today, the need to consider food and nutrition as fundamental elements of the planning process is becoming increasingly central to the political and scientific debate. In this regard, a proper integration between spatial planning and food planning allows us to address the current unsustainability of food systems, thus facilitating the development of transition processes towards more sustainable paradigms. This thesis wants to offer a complete picture of how over the years, food systems planning has become an indispensable component of spatial planning. In this regard, States around the world consider Food System Planning as a discipline capable of resolving the current levels of un-sustainability affecting, on the one hand, our societies and, on the other, our food systems.
