Methane is a potent, short-lived climate pollutant responsible for nearly 0.5°C of global temperature rise. Though it remains in the atmosphere for about 12 years, its climate impact is 86 times stronger than carbon dioxide over 20 years, making methane mitigation one of the most effective strategies for tackling climate change. The waste sector...

日本熱帯生態学会第36回大会公開シンポジウム＠大阪公立大学 近年、熱帯では小農が商業用農林産物の生産担い手として台頭している。 一方、商業用農林産物の生産拡大に伴う森林減少対策として、需要側アプローチ（Demand-side approach）による取組（認証、EUDR等）が拡大しているが、これらの取組は、効果検証が不十分なうえ、非効率、小農の排除につながる可能性がある。 いくつかの国では国家・準国家トレーサビリティシステム構築によって小農の需要側アプローチ対応を支援・包摂している。これらの取組は結果的にネーチャーポジティブ達成に貢献する可能性がある。

This paper examines the governance of agrivoltaics (AV) in the context of Japan’s rapid rural depopulation and farmland abandonment. While AV is traditionally framed as a solution to land-use competition, this study argues that in shrinking regions, the primary challenge is not land scarcity but a shortage of human capacity to manage...

Highland regions in Thailand are increasingly vulnerable to climate change due to rapid land-use transitions, environmental degradation, and shifting socio-economic conditions. This Discussion Papaer examines the drivers and dimensions of vulnerability in the Thai highlands, with particular attention to the expansion of maize cultivation and...

Protecting our oceans and advancing a sustainable blue economy require in-depth understanding of marine systems, driven by robust ocean observation, monitoring and valuation. Yet collecting reliable data remains time- and resource-intensive. This data is vital for scientists, emergency responders, and decision-makers to support early-warning...

This study provides an indicative comparative assessment of the factors underlying these challenges by examining policy content, regulatory enforcement, and institutional capacity related to OWB across ten selected Asian countries: Cambodia, China, India, Iraq, Jordan, Laos, the Maldives, Nepal, Pakistan, and Thailand. The researchers employed a...
