Climate-induced migration has emerged as a major concern in India and Bangladesh, due to their geographical vulnerability and socioeconomic conditions. Coastal areas, such as the Sundarbans and the Ganges–Brahmaputra Delta, face relentless threats due to rising sea levels, cyclones, and floods. These factors force millions to relocate, resulting in...

Climate change adaptation and loss and damage associated with climate change impacts are often confused at the practical level. These two concepts developed through negotiations under the UNFCCC mechanisms with certain political backgrounds, and they have been discussed separately since the Paris Agreement was adopted. However, apart from...

This study examines the factors influencing environmental migrants’ habitat preferences in southwestern Bangladesh. Using a multi-stage sampling technique, we selected 408 households in rural and urban areas, who had moved to their current locations due to climatic extremes.

Under the UNFCCC, the National Adaptation Plan (NAP) plays a central role as a policy framework for adaptation. While significant efforts, including research, have been made on the NAP scheme (which includes NAP formulation as one component), a critical evaluation of the entire NAP scheme is lacking. This includes an analysis of the relationship...

In a transition to a net-zero world, large-scale solar PV diffusion is essential in the Philippines and the entire ASEAN region, since its potential is much larger than wind and other renewable energies. Considering the vulnerability of the Philippines and accelerating climate change, it is also vital to make sure that net-zero transition based on...

地球規模で進む気候変動は、気象の激甚化、そして洪水や干ばつなどの自然災害を世界各地で引き起こし、新たな人道危機を生み出している。すでに社会基盤が脆弱化している紛争下の人々にとって、気候変動はリスクを増幅させる要因にもなっている。気候変動の負の影響が人類の発展や国際政治・経済の安定を阻むこの気候危機とも呼ばれる状況は、「気候安全保障」という視点から捉えることができる。人間の安全保障を掲げて開発援助に注力する日本にとって、気候危機下の人道支援の現状を分析・評価することは、今後の外交政策を展望する上で必須の課題だと言えるだろう。 気候安全保障は「日本国内に直接生じる安全保障リスク」と「日本国外で生じる安全保障リスクから波及して生じる日本の安全保障リスク」の２つに分類できる。本稿では...

Despite its socio-political importance, the significance of considering climate change from a security and diplomatic perspective has not yet been fully explored in the policy arena and on-the-ground actions. The...
