Urban agriculture (UA) is more than just the growth of food and raising of animals in urban and peri-urban spaces. It brings communities together, benefits people’s livelihoods, and helps to mitigate environmental issues in cities and surrounding regions. UA can be used within community-based research as a tool to build cohesion and to solve problems in the city. This chapter will highlight how UA is important to a City Region Food Systems (CRFS) approach to food system change, and how techno-urban agriculture initiatives linked to concepts like smart cities might help or hinder city’s capacity to meet their goals. The paper will also address how UA can be linked to international agreements like the Sustainable Development Goals (SDGs), the New Urban Agenda (NUA), and the Milan Urban Food Policy Pact (MUFPP). Quito, Ecuador will be discussed as an example of this engagement by highlighting their AGRUPAR Participatory Urban Agriculture program.
