This research project aimed to enhance the research capacity of scientists in South-East Asia on the subject of climate change with a focus on impact, vulnerability and adaptation, especially on rice production and water resources, which include assessment of impact, vulnerability and adaptation to climate change on the food production and water resource sectors. The major outcomes from this research consist of data, which have been used for many studies on climate change in the South-East Asia region. Further, the study develops a method on climate change impact, vulnerability and adaptation assessment which was tested in selected basins in Thailand and Lao PDR.
