A case study on regional arsenic sources and its distribution in Mekong River groundwater

Arsenic contamination in the Mekong River is a well-known environmental issue yet to be resolved due to its transboundary nature which further limits its access and data collection. Other than that, the key mechanisms that controlling the arsenic release in Mekong sub-region groundwater was heterogeneously distributed and can be varied from region to region. The...

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...

Climate-smart agriculture strategies for South Asia to address the challenges of climate change: Identification of climate-resilient agriculture practices for India, Bangladesh, and Afghanistan

In South Asia, agriculture is pivotal for food and nutritional security and the livelihood of more than 50% of the population. Food production and nutritional security pressures intensify as urbanisation decreases the agricultural land area amid population growth. Climate change complicates this scenario by introducing elevated temperatures, extreme climatic events, surging sea levels, and increased...

Dive industry perspectives on threats to coral reefs: A comparative study across four Asia-Pacific countries

The combined effects of climate change, marine tourism and other stressors threaten the ecological and economic sustainability of coral reefs. This study investigates dive industry stakeholder awareness of the threats to coral reefs through structured interviews with Dive Masters, company managers and marine management agencies in Vietnam, Australia, Malaysia and Indonesia. Stakeholders from all locations...

Climate change impacts on spatiotemporal variation of extreme weather and its consequences on dam optimisation and risk management in the Cagayan basin, Philippines

Extreme weather threatens livelihood and urban development in the Philippines. However, addressing their effects and occurrences is a significant challenge, particularly in the Cagayan River Basin (CRB), due to increasing population and the dilemma of dam operations for floods and droughts management. Therefore, this paper focuses on investigating the impact of climate change on extreme...

Farmers’ perceptions on the impact of climate change: Case study of the agricultural sector of Cambodia

This research aimed to assess the perception of farmers on climate change impacts and to find out existing coping mechanisms for climate change adaptation. Quantitative and qualitative approaches were adopted with a sample size of 320 using IBM’s statistical software SPSS version 21, which was used to analyse data, mainly descriptive statistics (frequency and percentage)....

Mapping groundwater resilience to climate change and human development in Asian cities

Groundwater resources in major Asian cities, including Bangkok and its vicinity, Ho Chi Minh City, Kathmandu Valley, and Lahore, confront escalating challenges due to climate change and human development. Over-extraction has led to groundwater depletion, causing socio-environmental and economic issues. This study investigates the combined impacts of climate change and urban development on groundwater resources...

Developing capacity for post-typhoon disaster waste management in Lautoka, Fiji, and Makati, Philippines

In recent years, Asia and the Pacific have been ravaged by strong typhoons that caused widespread destruction. The powerful winds from these typhoons ripped off roofs, windows, doors and walls from houses, and destroyed trees and other vegetation, leaving a vast amount of wooden, metallic, plastic, and glass debris and waste scattered across a wide...

Air quality management status and needs of countries in South Asia and Southeast Asia

Countries in South Asia and Southeast Asia are experiencing severe air pollution problems. Most countries lack technical capabilities and adequate air quality management (AQM) infrastructure. A capacity building workshop on AQM was organised from 19-23 September 2022 for countries in South Asia and Southeast Asia. A total of 17 countries (eight in South Asia and...

Capacity development of farmer group in using affordable micro-irrigation for small-scale farming in marginal land

Timely water availability and the use of traditional, less efficient irrigation methods are among the main constraints affecting the productivity of small-scale farming in many developing countries. Climate change, population growth, lack of skills and resources and less community resilience to respond are negatively affecting food security in many lower-income countries. Therefore, the use of...
