Climate change is an issue of concern in the Southeast Asia for the reason that, among many other impacts, it may cause shift and change in rainy season pattern that would directly affect agriculture activity and may threaten livelihood of large number of population in the region. In addition, the countries in the region, being developing country, may be vulnerable to climate change impact as they have limited resource to cope with future situation. However, these countries have limited knowledge on the subject and know-how to conduct further study on climate change as well as its consequences. This project aims to fill the gap by building research capacity in Lao PDR and Thailand. The capacity building approach under this project was not only based on conventional training and workshop alone, but also included pilot research practice on real case study which was conducted under guidance from SEA START RC by using data, method and know-how transferred from other global climate change programs, namely Assessment on Impact and Adaptation to Climate Change in Multiple Sectors and Multiple Regions (AIACC).
