Remediation of urban water bodies: A multi-country study on community capacity building and communication on nature-based solutions

Wetland degradation, driven by pollution and encroachment, presents a significant global challenge. This study explores the multi-country efficacy of Floating Treatment Wetland Systems (FTWS) as a Nature-based Solution (NbS) for remediating urban water bodies across Bangladesh, India and Nepal, using a common experimental framework that integrates an initially controlled microcosm study, followed by field trials...

Flood dynamics in the Vietnamese Mekong Delta from Earth observations

This study analysed flood dynamics in the Vietnamese Mekong Delta (VMD) from 2001 to 2023, using Terra MODIS MOD09A1 remotely sensed imagery data on the Google Earth Engine platform. The workflow includes data collection, preprocessing, flood extraction, and analysis of flood dynamics. We used the R programming language to analyse flood extent, duration, distribution, and...

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...

Mapping demographic proxy-based social vulnerability for small island coastal communities in a multi-hazard setting: Reference from Indonesia

Indonesia, with the world’s third-longest coastline and over 17,000 islands, faces significant risks from multiple hazards, including sea-level rise, floods, drought, wildfires, storms, and land subsidence. Social vulnerability in coastal communities, influenced by socioeconomic factors such as age, wealth, health, gender, and ethnicity, is critical to understanding their capacity to manage and recover from these...

Seasonal and climate-related variations in norovirus and PMMoV detection in Vietnamese oysters

Norovirus, a leading cause of acute gastroenteritis, significantly impacts global health, especially in developing countries where foodborne and environmental transmission remain challenging. This study examines the occurrence and seasonality of norovirus genogroups I (GI) and II (GII), their inter-annual variation and the prevalence of pepper mild mottle virus (PMMoV) as a potential viral indicator in...

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 for smallholder farmers on climate-smart agriculture via co-experiments in home gardens

In response to the growing impacts of climate change, Climate-Smart Agriculture (CSA) offers an integrated approach to enhance productivity, resilience, and emission reduction. This study promotes CSA adoption among smallholder farmers in northern Vietnam’s mountainous region by documenting the implementation and early outcomes of a community-based CSA initiative and drawing lessons for future scaling. The...

The perceptions of smallholder farmers to climate change and their responses through nature-based solutions in Northern Vietnam

The Northern Mountainous Region of Vietnam, home to diverse ethnic minority communities, is increasingly vulnerable to climate change, particularly in the agriculture sector. Smallholder farmers face mounting challenges due to shifting temperature and rainfall patterns. This study examines how smallholder farmers in Thai Nguyen and Son La provinces perceive climate change and the factors shaping...

The value chain analysis of PVC recycling in Pakistan: Challenges and opportunities for sustainable resource management

Despite the increasing emphasis on circularity and recycling, the incorporation of recycled plastic into new products remains constrained. This study focuses on the polymer-specific circularity of polyvinyl chloride (PVC), identifying challenges and opportunities within the value chain to foster circularity in Pakistan. Through a literature review and targeted data collection spanning across the PVC value...
