There were several suitable areas that were found to be optimal for urban farm development, and from these five sites were determined to be the best overall. Four of these five best sites are located within the boundaries of the priority neighbourhoods while the fifth site is located approximately 0.5 kilometers outside the boundaries of the Brant and Grange Hill East priority neighbourhoods. These five sites were selected as being more suitable than others because they had the top five suitability rankings (lowest 92.54% and highest 97.71%) in terms of all the factors that were involved in the MCE along with being large enough areas (minimum of 0.5 acres) to be considered for development.
Out of all five suitable sites, it was determined that the best site was site 1. The main limitation to this site was that it had the lowest suitability score out of all of the other sites (92.54%). However despite this, site 1 is the optimal location as it requires little to no development prior to use as an urban site whereas many of the other sites would have required tree removal, grants of permission, or raised beds.
Overall, the MCE model was useful in this project as it provided an opportunity to select a diverse range of possible sites for urban farm development in the city of Guelph. With additional analyses it was possible to look at the most suitable sites in greater detail to take into consideration the preparation of the sites for urban development when deciding on the best site. With this goal achieved it if fair to say that the overall study can be seen as a success as it fulfilled its purpose of determining suitable locations for possible urban farm development.
Acknowledging social, environmental and economic factors for this case study was essential in the final results which can also be applied in urban farming project in cities globally. Future GIS research in the field of urban agriculture should be to take into consideration other potential factors that may play minor roles in siting of an urban farm but would still be important to consider. This would include factors such as the the distance to water sources or major highways as other potential environmental constraints. Using more factors, even minor ones, in future evaluations of cities for urban agriculture would provide an increasingly accurate depiction of site suitability for urban agriculture.
