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...

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...

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...
