Quantitative monitoring of lake water storage in arid regions is essential for effective management of regional water resources, and can also elucidate the impacts of ecological degradation on lake water storage. This study investigates changes in water storage in Ebinur Lake, Xinjiang, from 2011 to 2024 using field–measured water depth data and...

Single-use plastic waste poses significant environmental challenges, particularly through microplastic pollution in aquatic ecosystems. In this study, a bio-carrier was fabricated from recycled single-use plastic waste, and its performance was evaluated in a laboratory-scale moving bed biofilm reactor combined with membrane filtration (MBBR-MBR)...

本書は、2010年に愛知県名古屋市で開催された生物多様性条約第10回締約国会議（COP10）に出席して以降の四半世紀に及ぶ著者の環境学に対する取り組みの歴史を振り返り、この分野における科学と政策のインターフェース強化に努めてきた自らの歩みを振り返ったものである。この時期は、国立大学法人化後の東京大学教授として初めて、東京大学教授と日本に本部を置く唯一の国連組織である国連大学の副学長を兼務し、多忙ながらも充実した研究者生活を過ごしていた。その当時から最近までの著者の主な研究・社会実践活動について、その成果を取りまとめたものである。 COP10の前後に著者は、中央環境審議会の委員（後に会長）や食料・農業・農村審議会委員に就任し、日本の環境政策や農業環境政策についてアドバイスを行う立場にあった...

国連環境計画（UNEP）が国連気候変動枠組条約（UNFCCC）第30回締約国会議（COP30）を前に発表した報告書「Emissions Gap Report 2025: Off target – Continued collective inaction puts global temperature goal at risk - Executive Summary」の日本語翻訳版（暫定非公式訳）。パリ協定発効から10年を迎える中、世界の気候行動は進展したものの、野心と実施は依然として必要水準に届いておらず、炭素集約型インフラの固定化や適応コストの高騰、人々や生態系への損失等をもたらしていると指摘し、パリ協定の温度目標達成に向けた緩和行動の加速こそが...

The Pact for the Future adopted in September 2024 calls for the 2027 SDG Summit to discuss advancing development goals beyond 2030.
