India’s national government has offered strong support for the development of green hydrogen as part of the clean energy transition. However, much of the actual progress in this transition will depend on subnational governments. This paper argues India’s subnational governments have significant potential to capitalise on diverse natural resource...

Water governance (WG) plays a crucial role in steering integrated water resources management (IWRM) toward the fulfillment of the Sustainable Development Goals (SDGs), particularly in developing regions. Despite this, substantial challenges hinder effective WG implementation across Asia. This study systematically reviews WG literature in Asia from...

Different baseline endowments and circumstances among countries, including local events, have resulted in disparities in energy policy and status. Differences in energy status have caused countries to make various decisions, but with the implementation of grid interconnections, some countries elected to plan the development of their energy sector...

本レポートは、世界平均気温の上昇を産業革命前と比べて１.5℃以内に抑えるという目標の達成に向けて、2050年までにカーボンニュートラルを実現するだけではなく、累積排出量をできる限り小さくする観点から、日本国内で早期に大幅な温室効果ガス（GHG）排出量削減を果たす可能性を検討し、その実現のためのアクションプランをまとめたものである。 2024年4月2日更新 謝辞の追記、出典の追記、誤記の修正を行いました。 企業の方向けに使いやすく再構成した「 1.5℃ロードマップ - 脱炭素でチャンスをつかむ。未来をつくる。 」もご活用ください。

This report examines the feasibility of Japan not only achieving carbon neutrality by 2050, but also making significant reductions in greenhouse gas (GHG) emissions, so as to make its cumulative emissions as small as possible, thereby contributing to the global goal of limiting the average temperature increase to below 1.5°C compared to the pre...

The purpose of this guide is to introduce the concept of landscape and seascape approaches (henceforth, “landscape approaches” for ease of reading), and how they can be applied to national biodiversity strategy and planning. Although it is written from the point of view of biodiversity conservation, it is aimed at all the many sectors that affect...

Nature-based solutions (NbS) are promising measures for protecting, sustainably managing, and restoring ecosystems as well as addressing societal challenges, including climate change mitigation and adaptation. To consider mainstream NbS for use in disaster risk reduction (DRR) infrastructures, the affected residents’ perception and attitude toward...

This is the Editorial of the first IGES-initiated Special Feature of the Sustainability Science journal. This Special Feature on Just and Sustainable Transitions in Net-Zero Asia aims to highlight how researchers, policymakers, and practitioners across Asia are applying just transition thinking to address pressing environmental challenges, climate...

This is part of the report for the 1st period (May 2022 to August 2023) of Project for the Development of Integrated Coastal Ecosystem Management System in the Republic of Mauritius, a JICA Technical Cooperation project. The work aimed to understand the current status of ecotourism and the potential of introduction of mangrove ecotourism in...

　北九州市は、市内の温室効果ガス（GHG）排出削減目標を掲げるだけでなく、アジア地域への貢献目標も掲げている。それは、アジア地域で、2050年までに、2013年度の市内のGHG排出量の150％以上に相当する排出量の削減を目指す（以下、「150％削減目標」という。）というものである。環境国際協力に長年取り組んできた「世界の環境首都」として、気候変動対策のようなグローバルイシューにも市内外で積極的に貢献していく姿勢を見せている。 　本稿は、北九州市の「150％削減目標」の意義や、その目標達成に向けたアプローチを確認した上で、政策効果の「見える化」の方法論について検討を行った。「150％削減目標」が数値目標であることを踏まえ、北九州市の取り組みのうちGHG排出削減量を把握できそうなものを特定し...
