also coupled with influence of climate variability based on farmers’ perspective. The
analysis of surveyed data, which focused on change in rice productivity under different
climate scenarios and its impact on farmers’ livelihood condition, showed that
vulnerability is site-specific condition, which depends upon the degree of climate impact
and socio-economic condition as well as physical condition of each site. The profile of
risk to climate change impact would differ from community to community.
The case study in Lao PDR shows that livelihood condition of farmer in Lao PDR
is low risk to climate impact, even though large number of population may be vulnerable
under certain conditions. Under climate condition at CO 2 concentration of 540ppm, over
80% of surveyed population in Lao PDR is classified under low risk category, while
approximately 10% is in moderate risk and only slightly over 5% is in high risk
categories. There is no substantial different between the situation under normal condition
and extreme climate event situation. When compare to the baseline condition, the impact
of climate change under normal condition would cause almost one-fifth of surveyed
population in Lao PDR to be vulnerable and more than half of the population would be
vulnerable in situation of extreme climate event coupled with climate change impact.
In the case study sites in Thailand, baseline risk assessment shows that
approximately one-third of survey population is low risk to climate impact, while the
moderate risk group is the largest group, which account for approximately 40-50% of the
surveyed population. Climate change has favorable impact on rice cultivation, but it
cannot cover the influence extreme climate event and cause large portion of population to
be vulnerable. In this case, many of those households in moderate risk group moved to
high risk group.
The impact of climate change under climate condition at atmospheric CO 2
concentration of 720 ppm causes only slightly change in rice productivity from the
condition under climate condition when CO 2 concentration is 540 ppm, therefore, has
little effect to the risk grouping in both case studies in Lao PDR and Thailand.
2.3.5 Adaptation of rain-fed farmer in Southeast Asia to climate change
Rice farmers in the Southeast Asia region are experienced in managing climate
risks and employ a variety of measures to reduce their vulnerability that are highly place
