The International Institute for Applied Systems Analysis (IIASA), in collaboration with its Japan National Member Organization (NMO), supported by Ministry of the Environment Japan (MOEJ) has initiated a joint research endeavor centered on Cities Transformation. The primary aim of this collaborative effort's inaugural phase is the compilation of a...

Globally, urbanization constitutes one of the major underlying drivers of global ecological degradation. Hence, deurbanization, i.e., demographic shift from urban to distant rural areas in a way that increases quality of life (QoL), can be one of the key pathways to address this global challenge. In this study, we investigated the contribution of...

Although the suburbs of numerous cities worldwide are shrinking, research on how to address suburban decline remains scarce. This paper explores participatory mapping in shrinking suburbs as a tool to articulate knowledge co-creation between local officials and communities to inform planning decisions. The paper argues that participatory planning...

This study analyzed the spatial-temporal change pattern and underlying factors in production-living-ecological space (PLES) of Nanchong City, China, over the past 20 years using historical land use data (2000, 2010, 2020). A land use transfer matrix was calculated from the historical land use maps, and spatial analysis was conducted to analyze...

Though the worst of COVID-19 appears to be over, it also raises important questions about COVID-19's immediate and then longer-term impacts on urban air quality. To understand both sets of impacts, the United Nations Environment Programme (UNEP) Asia Pacific Office, the Institute for Global Environmental Strategies (IGES), the Ministry of...

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...

Understanding institutional settings and governance processes is critical to the effective delivery of climate technology solutions for low-carbon and climate-resilient development in Asian cities. Creating the appropriate enabling environment for the development and transfer of climate technologies becomes imperative in this context. This requires...

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...

The main aim of this study is to comprehensively analyze the dynamics of land use and land cover (LULC) changes in the Bathinda region of Punjab, India, encompassing historical, current, and future trends. To forecast future LULC, the Cellular Automaton–Markov Chain (CA) based on artificial neural network (ANN) concepts was used using cartographic...
