Outline of Final Research Achievements

Statistical analysis based on interviews and questionnaires was conducted on the input workload and CO2 emissions of public green spaces/residential/agricultural land/woodlands and forests. The time footprint (RTF) of resource occupation for forest management was estimated separately for "mineral resources," "CO2 allowances," "labor," and "land," and scenario evaluation was conducted according to logging-branch recycling methods and management levels, and a method was developed to evaluate to what extent resource occupation differs according to management methods. As an additional study, we also obtained information on the number of visitors to the green space using location data to understand the actual use of the green space as well as the management aspects. The results of this research project have provided basic data on urban green space management from the perspectives of use, maintenance, and environmental impact.

Academic Significance and Societal Importance of the Research Achievements

人口減少による都市の空洞化や緑地保全創出に着目した研究には、緑地空間の確保可能性を検証するものが多く見られる。また、CO2排出を始めとする環境負荷に着目する研究は、整備段階を検証するものが多く、管理段階に重点を置いた研究は少ない。本研究の成果は、長期的な維持管理を要する緑地管理の環境性能や持続可能性に着目し、都市緑地における維持管理を対象に、ライフサイクルアセスメントの視点、持続可能性の視点を踏まえ、評価を試みたことに意義がある。
