An investigation of urban agriculture on residential blocks in Vancouver
Notice bibliographique
Résumé
Urban agriculture, which encompasses growing food on residential land, community and school gardens, rooftop gardens and inner city farms and any other food growing that occurs within a city, is an increasingly popular activity in the City of Vancouver. Urban agriculture has many environmental and social benefits and this is recognized in recent publications by municipal governments of the region. The focus of this project was to investigate how land is partitioned on residential blocks, how much residential land is being used to grow food, and if there is space and willingness to increase food growing on residential blocks. We also investigated whether residents would be willing to share their yard space if they have it. To answer these questions, we analyzed aerial photos of one block randomly selected from each of Vancouver’s twenty-two neighbourhoods and administered a survey to the residents of these neighbourhoods. We grouped the twenty-two neighbourhoods of our analysis into four categories based on their dwelling density. Some important findings were that 77% of Vancouver residents believe it is important to eat food that is grown locally, 52% of Vancouver residents grow some food for some period of the year. There is a significant correlation between individual residents’ responses relating to the importance of eating local food and whether they grow food. We also found that between 8-12% of the yard area of residential blocks is currently being used to grow food, which leaves space for food growing to increase. Our survey data indicates that there is not only available space, but also willingness on behalf of residents for food growing to increase. The data also indicates that given various conditions, at a minimum 26% of residents would be willing to share their yard space for others to grow food on. Based on the findings from our analysis of aerial photos and from our survey, we make the following recommendations: • Increase education on the benefits of growing food and how to tend a food garden in Vancouver. • Encourage and support Vancouver residents to grow food on residential spaces. • Support the existing supply of local food in its many forms and preserve existing agricultural land. • Provide more long lasting spaces for growing food for recreational and commercial purposes. • Use data on current high density areas as predictors for the needs of low and medium density areas in the future. Green space on residential blocks is an inventory of land that currently contributes to urban agriculture in the City of Vancouver. With appropriate action on behalf of residents and local governments, this inventory could be used to increase urban agriculture, which has the potential to benefit the City and its residents in various ways.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
