Table 9: Simulated yield of rice productivity at the 3 study sites under different climate scenarios<br />
5.3.3 Conclusion<br />
Climate change will have both positive and negative to the rice cultivation in the<br />
region. However, the result from the simulation is still somewhat differ from the actual<br />
yield according to surveyed data from field interview, perhaps due to the assumptions<br />
made for crop management and accuracy of other dataset used for the simulation,<br />
particularly soil property. Anyhow, these figures may be used as indicator to show future<br />
trend of the climate change impact on rice productivity in the Southeast Asia region.<br />
However, another significant climate impact on rice production in the study areas is from<br />
extreme climate event, such as flood, drought and dry spell, etc, which may increase in<br />
