Uncovering the potential for increased food security in Vancouver BC : a comparative analysis of three commercial buildings with rooftop gardens

Abstract

Rooftop gardens are an important tool within sustainable urban agriculture (UA) that can contribute towards food security. This paper explores the barriers, benefits and incentives of rooftop gardens which have documented environmental and social benefits, including use as a tool towards combating climate change and for creating community within cities. Significant barriers exist, with opportunities for mitigating such barriers and creating incentives for participation in rooftop UA including grant programs specifically designed to guide businesses through implementation of gardens on commercial buildings, rooftop restaurants for increasing tourism potential, change in policy for support of UA, awards for businesses who are leaders in using roof space for food production, innovations in design, and education and training. Rooftop UA has potential for growth in Vancouver, if impetus comes from various sectors, including government, non-profit organizations and the City of Vancouver, with specific emphasis on making rooftop UA exciting for business and profitable.
