2 Executive Summary
2.1 Research problems and objectives
Research problems:
o What are impacts of climate change on the hydrological regime and fresh water
resources in Mekong River Basin
o What are impacts of climate change on rain-fed rice productivity in Mekong River
Basin
o How would rain-fed farmer in the region be vulnerable to the impact of climate
change
o How would rain-fed farmer in the region adapt to impact of climate change
Objectives:
o To develop high resolution climate scenario - in terms of geographical and
temporal
o To understand the impact of climate change on regional hydrological regime and
rain-fed agriculture in the Mekong River basin.
o To develop and test framework and method to measure vulnerability of household
in the community to climate impact.
o To understand coping capacity and adaptation to climate impact of the rain-fed
farmer in the lower Mekong River region.
2.2 Approach
This study can be divided into 2 parts, which used different approaches in the study.
o The study on climate change and its impact on biophysical systems are based on the
modeling approach. This area of study was focused on changes in climate pattern and
its first order impact on hydrological condition and agriculture, particularly the rainfed
system, in the region. Climate model was used to simulate high resolution future
climate scenario. Climate change impact was analyzed by using future climate data
from the simulation as input to hydrological model and crop model for further
