Ecological conservation has become a core issue of global concern, and ecosystem services (ES) are fundamental to achieving sustainable development. However, integrated assessments of ES dynamics, spatial heterogeneity, and future land use scenarios in Mongolia remain insufficient. This study utilized Land Use and Land Cover (LULC) data from 2000...

The Association of Southeast Asian Nations (ASEAN) has become one of the most important regions in the global climate debate because it combines rapid economic growth, rising energy demand, and high climate vulnerability. This regional context has become more urgent after the outcome of the first Global Stocktake (GST 1) adopted at CMA.5 in 2023...

Microplastic pollution in tropical urban rivers has become an increasing environmental concern due to rapid urbanization, inadequate waste management, and hydrological transport processes. This study investigated the occurrence, characteristics, and spatiotemporal distribution of microplastics in the Can Tho River, Vietnam, along an urban– peri...

This presentation reflected on the experience of developing the ASEAN Climate Change Strategic Action Plan 2026–2030 (ACCSAP) to examine how evidence can move beyond assessment and analysis to influence policy and support implementation. The ACCSAP experience showed that evidence becomes policy-relevant not simply through technical quality, but...

Typhoon impacts in the Philippines exhibit strong neighbour hood-scale heterogeneity driven by interactions among haz ard intensity, exposure, and vulnerability, yet most opera tional assessments remain hazard-centric. This study presents a grid-based machine-learning framework for neighbour hood-scale typhoon risk mapping integrating geophysical...

Typhoon impacts in the Philippines exhibit strong neighbourhood-scale heterogeneity driven by interactions among hazard intensity, exposure, and vulnerability, yet most operational assessments remain hazard-centric. This study presents a grid-based machine-learning framework for neighbourhood-scale typhoon risk mapping integrating geophysical...

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。

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...

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...

東南アジア地域における急速な都市化と消費拡大に伴い、プラスチック廃棄物の発生量が急増し、プラスチック汚染が特に深刻な課題となっている。ASEAN諸国では、使い捨てプラスチックの禁止、拡大生産者責任（EPR）制度、普及啓発キャンペーンなど、さまざまな対策が進められている。しかし、これらの対策だけでは、根強く定着した消費行動を変えるのは難しい。 利用制限や普及啓発だけで十分な効果が得られないような課題に対し、行動科学は有効な補完的アプローチとなる。Behaviour-Centred （行動に関する理解に基づく、行動に焦点を当てた）アプローチを取り入れることで、単なる情報提供や経済的インセンティブに頼るのではなく、「意図と行動のギャップ」を埋め、持続可能な行動変容を促すことができる。...
