This research investigates the potential of utilizing recycled concrete aggregate (RCA) and recycled sand (RS), derived from crushed concrete cubes, as sustainable alternatives in construction materials. The study comprehensively evaluates the properties of RCA and RS, focusing on workability, impact resistance, abrasion resistance, and compressive...

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...

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...

Monitoring Sustainable Development Goals (SDGs) has mainly focused on levels of achievement of targets and indicators, but few studies have examined policies and implementation efforts systematically. The Sustainable Development Solutions Network (SDSN) has called for more monitoring of policy efforts, which is necessary to understand why overall...

The 17 Sustainable Development Goals (SDGs) broadly cover the social, economic and environmental dimensions of sustainable development. Achieving one target will affect the achievement of others through their intrinsic linkages, either positively or negatively. Achieving the SDGs requires an integrated approach. Existing knowledge on SDG...

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 study delves into the patterns of urban expansion in Kabul, using Landsat and Sentinel satellite imagery as primary tools for analysis. We classified land use and land cover (LULC) into five distinct categories: water bodies, vegetation, barren land, barren rocky terrain, and buildings. The necessary data processing and analysis was conducted...

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...
