How has sustainable transport been discussed in the international community? First, let’s take an overview of the history of the SDGs. In June 1992, the United Nations Conference on Environment and Development (UNCED), also known as the “Earth Summit,” was held in Rio de Janeiro, Brazil. The Earth Summit was a conference aimed at obtaining concrete...

From 24 to 27 February 2026, the UNDP held a training course in Yokohama for 40 ASEAN officials on the link between measures to tackle marine plastic pollution and the tourism sector. Mr. Hiroshi Ono, Executive Director of IGES, shared Japan’s experience on Circular Economy and waste management policy development, helping the participants to gain...

Aquatic food systems are essential to global food security and biodiversity but remain underserved by existing sustainability indexes, especially amid rising uncertainties and accelerating climate change. Current frameworks are fragmented, environmentally weighted, and insufficiently inclusive of social, economic, and governance dimensions. As we...

Sunda clouded leopard conservation requires understanding key species traits. Using photo-identification, we estimated lifespans from minimum residence times, documenting the oldest wild individual known to date—a 6.51-year-old female. We discuss methodological limitations in female detectability and transient individuals in the population and...

Climate variability poses a serious challenge to the sustainability of fragile mountain ecosystems where local livelihoods are closely dependent on natural resources. However, limited studies have examined long-term trends and local perceptions of climate variability in the north-eastern region of Dimapur district of Nagaland state in India. Thus...

都市の自然環境（都市緑地を含む）は，心理的回復，社会的結束，環境学習の機会を提供することが広く認識されている．人間と自然との関係性に関する学術的議論は，バイオフィリア仮説や注意回復理論などの理論枠組みに加え，健康・生態・経済・環境にわたる幅広い体系的レビューや実証研究によって発展してきた．しかしながら，こうした進展にもかかわらず，特定の都市や地域に内在する多様な生態的・社会的特性に着目した研究や，小規模コミュニティを対象に，簡潔かつ多角的な指標を用いて，記述的・探索的に人と自然の関係性を捉えようとする研究は相対的に少ない．都市公園はネイチャー・ポジティブ戦略の主要な実践の場であり，場所固有の特性を踏まえたコミュニティ主体の自然再生・共生の取り組みが不可欠である．そのためには...

The intensification of agriculture, coupled with unregulated fertilizer application and groundwater overexploitation, has led to widespread nitrate (NO3􀀀 ) contamination in many agrarian regions, including the Malwa region of Punjab, India. This study employs the Water Evaluation and Planning (WEAP) system to simulate the spatio-temporal evolution...

Bangalore, a rapidly urbanizing technological hub, faces escalating energy demands that require sustainable solutions. This study uses Google Earth Engine to assess Bangalore's solar energy potential through geospatial modeling and advanced suitability analysis. Utilizing high-resolution geospatial data, this study analyzed environmental and...

北九州市は、令和７年５月に北九州市生物多様性戦略（以下「戦略」という。）を改定し、北九州市が有する都市と近接した豊かな自然「アーバンネイチャー」を活用し、①生物多様性を大切にする価値観の形成、②生物多様性の保全と回復、③自然を活用した多様な課題の解決、を３つの柱として、生物多様性の損失を止め回復軌道に乗せる、いわゆる「ネイチャーポジティブ」の実現を目指し、取組を進めている。 それに当たり、産学官民が一体となり戦略を推進する「北九州ネイチャーポジティブネットワーク」（以下「ネットワーク」という。）と、その中核的機能を担う「北九州ネイチャーポジティブセンター」（以下「センター」という。）を新たに創設し、それぞれの主体の連携・協働により、オール北九州でネイチャーポジティブに取り組んでいく必要がある...

Effective disaster risk reduction in developing countries requires policies that are systematically informed by scientific evidence. This paper investigates how science–policy integration for disaster management and climate adaptation has been institutionalised in three international reference cases (Japan, the United States, and the Netherlands)...
