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...

Formation mechanism and source apportionment of nitrate in atmospheric aerosols

Atmospheric particulate nitrate is relevant to various atmospheric processes and shows profound impacts on regional air quality and global climate change. Exploring the formation mechanism and sources of nitrate in atmospheric particulate matter is essential for the successful mitigation of nitrate. This review summarises the different formation mechanisms, sources, and source apportionment methods of nitrate....

Climate change risk perceptions, vulnerability, and adaptation in high altitude farming regions of Hindu Kush Himalaya

Hindu Kush Himalaya (HKH) is highly vulnerable to climate change, but there is the least understanding of the impacts of climate change. This study explored local climate change risk perceptions, vulnerability, and adaptive responses in the three HKH countries, Pakistan, Nepal, and Bhutan. For this purpose, 379 farm households from low, medium, and high elevations...

Strengthening adaptive capacities of small holding South Asian agrarian community through Climate Information Network -based decision support tool

Marginal farmers in rain-fed agrarian systems can benefit immensely from real-time contingency planning and decisionmaking tools in the climate milieu. Long-term climate anomaly prediction of some selected locations was made. Forty-two Global Circulation Models (GCM) from the Coupled Model Intercomparison Project Phase 5 project (CMIP5) were used for the present work and Representative Concentration Pathway...

How to measure urban water security? An introduction to the Water Security Assessment Tool (WATSAT)

The objective of the project was to develop a web-based digital tool called the Water Security Assessment Tool (WATSAT) to help city authorities and decision-makers make an objective evaluation of the water security situation in the city. It uses an indicator-based methodology that measures five distinct dimensions (broad elements) of water security: “Water supply and...

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...
