terms of frequency and severity as impact of global warming. Based on farmer interview
at the study sites, especially in Thailand and Lao PDR, the extreme climatic events may
cause loss of rice productivity by average 30-50% from flood in moderate flood year.

5.4 Assessment on vulnerability and adaptation of rain-fed farmer in the lower Mekong
River region to climate change
The rain-fed farmer in the lower Mekong River region could be among the most
vulnerable group as their livelihood depends heavily on their annual on-farm productivity,
particularly the rice cultivation, which is directly exposed to climate risk. In addition,
household economic condition of these farmers is also considered to be in the poor group
in the society, thus may cause them to have limited resource or other capacity to cope
with impact of climate variability and change. Assessment of risk and vulnerability of the
rain-fed farmer of the lower Mekong River region in this study was based on field
interview to assess baseline livelihood condition and also baseline climate risk, which
will be further used in the analysis on vulnerability to climate change impact.
5.4.1 Description of Scientific Methods and Data
The assessment on risk and vulnerability to impact of climate change was based
on change in rice productivity under different climate scenarios, which was used as a
proxy of stress from future climate change, and analyzes its effect on the household
livelihood condition according to the following diagram.
