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...

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...

Salinity intrusion has become a critical threat to agricultural stability and water resource management in the Vietnamese Mekong Delta (VMD), particularly in coastal regions. This study evaluates the efficacy of the Long Short-Term Memory (LSTM) neural network, a sophisticated deep learning (DL) architecture, for predicting salinity concentrations...

Single-use plastic waste poses significant environmental challenges, particularly through microplastic pollution in aquatic ecosystems. In this study, a bio-carrier was fabricated from recycled single-use plastic waste, and its performance was evaluated in a laboratory-scale moving bed biofilm reactor combined with membrane filtration (MBBR-MBR)...

Using behavioral science to reduce plastic waste on the UP Diliman campus The University of Philippines Diliman (UP Diliman) initiative, led by UP Diliman with support from the Economic Research Institute for ASEAN and East Asia (ERIA), Institute for Global Environmental Strategies (IGES), and Rare, tackled plastic waste generated by a dense campus...
