Outline of Final Research Achievements

This study aimed to visualize small-scale urban food systems in Japanese suburban areas with mixed green, agricultural, and residential land uses using the concept of "Foodshed" and examined their effectiveness from the perspective of resource circulation. Questionnaire surveys and interviews with urban farmers and community gardeners in Tokyo revealed that small-scale circular food systems were formed within a range of a few hundred meters to a few kilometers, encompassing the entire food system from production to distribution, consumption, and organic waste recycling. Additionally, a survey conducted during the COVID-19 pandemic showed that local food accessibility in these urban areas was significantly associated with urban residents' subjective well-being, physical activity, and food security concerns, indicating that small-scale circular food systems functioned effectively.

Academic Significance and Societal Importance of the Research Achievements

本研究はFoodshedの概念を用いて、日本の都市の緑農住混在市街地における小規模分散型フードシステムを可視化した。また、本研究の途中で、COVID-19パンデミックが発生したため、研究内容を一部変更し、COVID-19蔓延下において小規模分散型フードシステムが都市住民の健康と食料不安の緩和に果たした役割を明らかとした。これらの結果は、都市における資源循環並びに健康促進のために緑・農・住が混在する土地利用形態の有効性を示すものである。本成果は、これまで乖離していた都市計画と食料の資源循環を統合的に捉え、循環型都市(サーキュラー・シティ)を構築していくための基礎的知見を提供している。
