Assessing urban heat islands in Southeast Asia megacities: An integrated study of land use, climate change and heatwave occurrences

Rapid urbanisation and climate change are intensifying Urban Heat Island (UHI) effects across Southeast Asian (SEA) megacities, compounding heatwave risks and threatening urban sustainability. This study, conducted under the Asia-Pacific Network for Global Change Research (APN) collaboration, presents the first integrated, multi-decadal assessment of UHI–heatwave interactions in SEA, focusing on Kuala Lumpur as a representative...

Status, policy analysis and management-based approaches for coral reef restoration in Cambodia, Thailand and Vietnam

Southeast Asian coral reefs in Thailand, Cambodia, and Vietnam are critical socio-economic assets, generating over USD 11 billion annually. However, they face escalating threats from climate change and local anthropogenic stressors. Synthesising empirical field data, remote sensing and research outcomes from the APN CRRP2019-08MY-Khanal project, this review reveals significant regional degradation. Specifically, Vietnam has lost...

Capacity development training workshop on crop simulation modelling and effects of climate risks on agricultural production systems in Southeast Asia

Southeast Asia (SEA) has experienced frequent floods and droughts, posing severe challenges for farmers, agricultural scientists and extension officers. Consequently, crop modelling has become imperative in developing agricultural production systems and making informed decisions at the field level. The Decision Support System for Agrotechnology Transfer (DSSAT) can be effectively utilised at both farm and regional...

Future changes in mean and extreme precipitation over Peninsular Malaysia using CORDEX-SEA 5 km simulations

The Coordinated Regional Climate Downscaling Experiment (CORDEX) Southeast Asia further downscaled three of its 25 km products, i.e. EC-Earth, HadGEM2-ES and MPI-ESM-MR forced regional climate simulations to a higher resolution of 5 km. A newer RegCM4.7 model was used for this exercise. For the simulations over Peninsular Malaysia, analysis shows that these simulations have much...

Factors influencing farmers’ climate change adaptation in Southeast Asia: A comparative study from Vietnam, Laos, and Cambodia

Southeast Asia is among the most climate-vulnerable regions in the world. Despite this, little is known about how climate change adaptation at the household level differs across countries in this geographic region. This cross-country study investigated factors influencing adopting three adaptation practices: growing climate-tolerant crops, intercropping, and switching to cash crops in some selected provinces...

Climate change scenarios over Southeast Asia

Southeast Asia is one of the world’s regions most vulnerable to climate change impacts with low-lying land, more severe floods and droughts, larger populations, higher dependency on agriculture for the economic sector, and low resilience of communities. Therefore, a study on how future climate change will affect this region has been conducted, and the results...

Impact of biomass burning sources during the high season on PM2.5 pollution observed at sampling sites in Hanoi, Vietnam and Chiang Rai, Thailand

This study aimed to assess PM2.5 concentration and the potential impacts of biomass burning sources on PM2.5 measured at the sampling sites in Hanoi, Vietnam and Chiang Rai, Thailand during the high season (from January to April) in 2021 in which intensive biomass burning activities occur in Southeast Asia (SEA) region. For this purpose, an...

Rapid mapping technique for data acquisition: The case of a summer school in the Banjarnegara district, Indonesia

Global environmental change makes us aware of the impact of natural hazards. Natural hazards are phenomena with large spatial dimensions and impacts but whose mapping and monitoring data can be recorded only by using satellite or aerial remote-imaging platforms (Poursanidis & Chrysoulakis, 2017). Given that Southeast Asia is the region in the world that is...

Consumers’ risk perception of vegetables in Southeast Asia: Evidence from Laos, Cambodia, and Viet Nam

Vegetable safety is a public concern in Laos, Cambodia, and Viet Nam—developing countries in Southeast Asia. Eliminating this concern requires insight into factors shaping it. Food risk perception might differ among countries due to the dissimilarities in culture, social, and economic conditions. However, an understanding on this difference is lacking in Southeast Asia. This paper...

Appraising slow onset hazards for loss and damage: Case studies in Southeast Asia

Slow onset processes were investigated in five pilot areas in Southeast Asia, i.e., Kampong Speu Province (Cambodia), Selangor State (Malaysia), Thatdama Kyun Village (Myanmar), Kanan Watershed (Philippines), and Quang Ngai Province (Vietnam). Pilot areas with low-lying coasts are exposed to floods, saline intrusion and sea-level rise while some are also affected by storms and typhoons....
