Understanding water security in a peri-urban region: A study from two South Asian countries

Research on water security in peri-urban regions of South Asian countries remains limited. We employed the Problem and Solution Tree tool to analyse the factors that impact water security in this region, specifically Nepal and Bangladesh. Water security in the peri-urban region in Nepal is related to the quantity of water, i.e., availability and distribution...

How livelihood assets influence the multidimensional poverty status of mountainous farmers in Central Vietnam

The role of livelihood assets in alleviating multidimensional poverty among marginalised groups in developing countries is paramount. This study aims to investigate the impact of livelihood assets on multidimensional poverty in a vulnerable context by surveying 320 farmers in the mountainous regions of central Vietnam. The findings revealed a high household headcount ratio of multidimensional...

Strengthening the capacity of officials on Integrated Flood Management Plans into provincial disaster prevention plans in the coastal provinces of Central Vietnam

In Vietnam, under the effect of climate change, natural catastrophes, particularly storms and floods, cause more and more destruction, especially in the central region. However, the capacity of localities in integrated flood management is relatively low in the target provinces. To support the reduction of flood risks, the training workshops on “Strengthening the Capacity of...

Influence of transboundary air pollution into the atmosphere of Kathmandu Valley

Air pollution is a major problem of the 21st century, bearing most of the burden in South Asia, with the highest rate of particulate matter (PM) concentration in recent years. This paper assesses transboundary air pollution in Kathmandu Valley's atmosphere originating from both neighbouring countries and regional sources within Nepal. Daily average PM2.5 data (2017–2013;2020)...

Overcoming barriers to agroforestry adoption: Empowering local farmers through participatory establishment of agroforestry models in Laguna, Philippines

Agroforestry has been recognised as a sustainable farming system that offers multiple environmental and socioeconomic benefits. However, adoption remains a challenge primarily due to a lack of awareness, limited knowledge, and firsthand experience among local farmers. This initiative aimed to address this gap by establishing agroforestry models through a participatory approach in Barangay San Cristobal,...

Strengthening livelihood resilience through community-based aquaculture in rural Northern Thailand: Successes and challenges

A multi-site community-based aquaculture system (C-BAS) initiative was launched across 14 villages in northern Thailand in 2023 to enhance food security and livelihood resilience. A mixed-methods approach combined the Community Aquaculture Viability Index (CAVI), Community Capacity Assessment (CCA) and cost-benefit analysis to evaluate social, technical, economic and environmental dimensions of success. Seven sites were successful:...

Mass distribution of PET and PC microplastics in the atmosphere of Tianjin, China

Microplastics (MPs) in the urban atmosphere have been widely reported. However, the distribution of urban atmospheric microplastics (AMPs) under the influence of the East Asia monsoon remains unknown. In this study, total suspended particle (TSP) samples were collected, and polyethene terephthalate (PET) and polycarbonate (PC) MPs concentrations were quantified using a liquid chromatography-tandem mass spectrometry...

Socio-ecological approaches in the science of pricing ecosystem services: A perception-based study in some wetlands of Asia and the Pacific

Ecosystem services are natural benefits that support the lives and livelihoods of humans and are classified as use and non-use types, for provisioning, regulatory, supportive and cultural features. For the valuation and pricing of intangible non-use ecosystem services, several methods have been proposed, including accounting for loss and damage, or compensating opportunity costs. This study...
