Urban agriculture provides many benefits, such as energy conservation, rainwater remediation, increased aesthetic and property value, and therapeutic use for physical, cognitive, and emotional wellbeing. Urban agriculture can also provide critical integrity to each pillar of food security: availability, access, utilization, and stability. As urban agricultural activities increase, social interactions will follow in concert. This will provide opportunities for building trust through the two-way communication of contrasting perspectives, cultures, and beliefs using impartial narratives. Growers can use knowledge and understanding gained from these positive social interactions to formulate their personal paradigms for practice and better meet the needs of each stakeholder. Growers of all levels of expertise are encouraged to constantly investigate assumptions and build capacity for understanding their socio-environmental systems. Special considerations are suggested in this document for developing desirable characteristics in urban soils and for designing a food crop production plan that is in continuous evolution with the production system.
