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...

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...

The global population is concentrating unprecedentedly into urban areas, raising concerns on global sustainability and human well-being. There also exists a niche trend of migration from urban to rural areas particularly in countries with post-industrial economies. This paper investigated values of migration expressed by the migrants arrived in...

A Post-2020 Global Biodiversity Framework is currently under consideration and will be adopted at the next meeting of the Conference of the Parties to the CBD (CBD COP 15). In Japan, discussions are underway to revise the National Biodiversity Strategy and Action Plan (NBSAP). Local governments are expected to develop new, or revise existing, Local...

Research on the service values of urban ecosystems is a hot topic of ecological studies in the current era of rapid urbanization. To quantitatively estimate the ecosystem service value in Chengdu, China from the perspectives of natural ecology and social ecology, the technologies of remote sensing (RS) and geographic information system (GIS) are...

プラスチックの生産と消費パターンの拡大、とりわけ使い捨てプラスチックや不適切なプラスチック廃棄物の処理に伴い、海洋生態系でのプラスチック廃棄物の蓄積が急増している。海洋のプラスチック汚染の主たる原因（海洋ゴミの約80％）は陸上から海へ流出するプラスチックである事が知られており、海洋のプラスチック汚染は世界的な関心を集める課題となって多くの政府や自治体が対応策を模索している。 より環境にやさしく持続可能なプラスチックの生産と消費を行う社会を実現するには、様々な利害関係者の参加と監視・評価に基づく長期的な取り組みが必要である。その第一ステップとして本レポートは、利害関係者の参加を促進し、国の廃棄物処理方針に沿った廃プラスチックを抑制する包括的な計画の開発を提言する。そのため、IGES-CCET...

Accumulation of plastic wastes in the marine eco-system is growing rapidly with the increase of plastic production and consumption patterns, particularly single-use plastics as well as unsustainable plastic waste management practices. Land-based sources are recognised as the main cause (up to 80% of total marine debris) of marine plastic pollution...

Tonle Sap Lake (TSL), the largest lake in South East Asia, is under increasing pressure from pollution, land-use change, climate change, and development activities in the lake, its basin and the Mekong Basin. Recent changes in the lake hydrological system and its floodplains are becoming a great concern for hundreds of communities relying on the...

Previous studies have demonstrated the role of nature connectedness in promoting human well-being. However, recent studies put emphasis on understanding the underlying mechanism that drives the association between nature connectedness and well-being, mainly mental health. Place attachment is one of the place-based socio-psychological concepts that...

Green fractional vegetation cover (fc) is an important phenotypic factor in the fields of agriculture, forestry, and ecology. Spatially explicit monitoring of fc via relative vegetation abundance (RA) algorithms, especially those based on scaled maximum/minimum vegetation index (VI) values, has been widely investigated in remote sensing research...
