It is widely agreed that a sustainable city should meet the needs of the present generation without sacrificing the ability of future generations to meet their own needs. However, there has been no completely agreed-upon definition for what a sustainable city should be nor upon the paradigm for what components should be included. On the other hand, there is a possibility that the multi-functions of urban agriculture may attract especially those who are thinking creatively. These creative thinkers have a high level of social capital, pay attention to social issues, and are greatly motivated to find solutions through social enterprises such as agriculture-related business.
