In order to feed the ever increasing global population without further degrading the natural environment we need to create a more sustainable food system utilizing small scale intensive (SPIN) methods of urban agricultural production.

This paper looks at the history of agriculture and the current food system as a basis for understanding its future and investigates the need and conditions to create a resilient food system. Viewed through a Toronto-centric lens to better understand how implications may affect urban rooftop agriculture, this paper presents arguments for the intensification of rooftop agriculture and the decentralization of the food system. Strategic foresight is engaged to understand not only the ecological and environmental impact of the agricultural system, but also the importance of food security itself.

Rooftop agriculture has the potential to add resilience to our food system while providing social, economic and environmental benefits for all Torontonians.
