With the mounting pressure of urbanization, how innovative blue-green infrastructure (BGI) can restore the ecosystem services of urban rivers is a timely issue for any densely populated city seeking to improve its resilience and sustainability through ecosystem-based solutions. Yet, the implementation of BGI is not hazard-free. Its success usually...

Urban rivers in Singapore are surrounded by concrete embankments and riverbeds that degrade the natural ecosystem and ecosystem services. The Singapore government has taken up several initiatives to restore the urban environment and the ABC program is a significant one among them. Many factors have played a role in the success of the ABC program...

The commons concept has evolved in multiple ways after the publication of Ostrom’s seminal work in 1990, which emphasized the evolution of resource management institutions and the usefulness of self-governance. As we move into the 21st century, one of the institutional transformations is catalyzed by the emergence of Information and Communication...

本調査では、スウェーデン、デンマーク、ドイツ、フィンランド及びフランスの 5 カ国を対象に、各国の持続可能な開発目標（SDGs）の①実施体制、②進捗状況の評価方法、③その 他独自の取組を調べた。これらの国は持続可能な開発ソリューション・ネットワーク（SDSN）とベルテルスマン財団が発表している SDG 指数等、SDGs の進捗状況に関する世界ランキ ングで常に上位につけている。これらの国の実施体制や進捗状況の評価方法等を理解する ことは、日本を含む他の国々における SDGs の実施を強化するのに有益と考えられる。 調査は、机上調査と聞き取り調査を組み合わせる手法をとった。机上調査では、各国の自発 的国家レビュー（VNR）、SDGs 行動計画、その他の関連文書を精査した。さらに、5...
