We utilize the roof of the building and fallow land in cities, and aim at diffusing the hydroponics farming intended for the retired workers and city people. In cities, centralization of various functions, decrease of green zone, and collapse of community pose the environmental problems such as heat-island phenomenon and other issues. Consequently, interactions between people are now decreasing. Utilizing the roof gardening and fallow land by hydroponics contributes to the reduction of the heat-island phenomenon and revival of the related community, which brings the city people “comfort” and “pleasure.” In addition, we believe that our activity can also bring us “improvement in food self-supporting ratio” by returning to the farming.
