Through a study of Ra Province (northeast Viti Levu Island, Fiji) involving both archival research and community engagement, we highlighted a long history of Indigenous population mobility. Many coastal settlements have mostly undocumented histories of relocating inland due to shoreline retreat and land loss over recent decades. Studies of...

IGES's Hotta presented on Japan's marine plastic waste countermeasures and policies at an international conference on marine plastic pollution hosted by Ocean Conservation Administration in Taiwan. This conference featured contributions from government officials and experts from Japan, the United States, and Republic of Korea, primarily focusing on...

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 study examines land use changes and evaluates the past and projected forest carbon sequestration and its valuation in Viti Levu Island, Fiji, through a combination of remote sensing with a geospatial-based modeling approach. Land use classification was performed using Landsat 7 and Landsat 8 imageries of the years 2000 and 2020; then, cellular...

With the mounting pressure of urbanization, how innovative blue-green infrastructure (BGI) can restore the ecosystem services of urban rivers is a timely issue for any densely populated city seeking to improve its resilience and sustainability through ecosystem-based solutions. Yet, the implementation of BGI is not hazard-free. Its success usually...

The commons concept has evolved in multiple ways after the publication of Ostrom’s seminal work in 1990, which emphasized the evolution of resource management institutions and the usefulness of self-governance. As we move into the 21st century, one of the institutional transformations is catalyzed by the emergence of Information and Communication...

Home to roughly 1.8 billion people, South Asia generates approximately 334 million tonnes of waste per year of which 174 million tonnes (57%) is organic in content. In addition to the increase in municipal solid waste, managing complex and emerging waste streams, including e-waste, food waste, construction and demolition waste, disaster waste...

In this study, a methodologies and a case analysis of sustainability of WEEE recycling systems (e.g. Washing machines, Refrigerators, Air conditioners and Televisions) was developed based on the case of Japan’s home appliances recycling system. In addition, to enable comparative analysis, we have conducted field surveys in Taiwan and India and...

本研究では、2012年度以来3年間の予定で、リサイクルシステムの持続可能性評価を、環境・経済・社会的な視点から評価するための分析枠組みの開発を試みている。本研究では、まず日本の家電リサイクル法の下でのリサイクルメカニズムを事例に、環境、社会、経済という持続可能性の各側面を評価するための定量分析手法の開発を、ライフサイクル分析の手法を用いて行った。その上で、台湾、中国、インドについても、廃電気・電子製品のリサイクルメカニズムの実態について、調査し、同様の手法の応用を試みているところである。最終的には、国際比較を行うことで、国際資源循環を含む、適正な資源循環の在り方について提言することを目指している。 本発表では、上記の研究の中から...
