2.2.2 Assessment of vulnerability and adaptation to climate impact: field survey approach
The assessment on risk and vulnerability of rain-fed farmer to climate impact in this
study was based on field survey to collect data for the analysis of baseline livelihood of
rain-fed farmers in the selected study sites, and also for multi-criteria analysis in
measuring risk to climate impact. The three criteria used in this study in the assessing
farmer’s risk to climate impact are as follows;
o Household economic condition, which was used to measure the sensitivity of the
farmer household to climate impact.
o Dependency on on-farm production, which was used to measure the exposure of
the farmer household to climate impact.
o Coping capacity to climate impact.
Change in rice productivity under influence of climate change and extreme climate
event was used as proxy of threat from climate impact in the analysis process. Adaptation
to climate change was also assessed by field interview and local stakeholders meeting,
which mainly focus on the opinion of the farmers in the study sites.
2.3 Scientific findings
2.3.1 Future climate change in Southeast Asia: lower Mekong River basin
The climate scenario simulation in this study was
conducted for the whole region of Southeast Asia and also
southern part of People Republic of China for the period of
10 years at each atmospheric CO 2 concentration level.
However, the analysis and verification/adjusting process
was focused on the Lower Mekong River basin in Lao PDR,
Thailand and Vietnam only. This is due to the limited
availability of the observed climate date which is required
for adjusting process.
Figure 1: Focus area of climate
change scenario analysis
The climate scenario shows that the region tends to get slightly cooler under
climate condition at CO 2 concentration of 540ppm but will be warmer under climate
condition at CO 2 concentration of 720ppm. However, change in temperature under this
