From comparative analyses, it is found that both rice production and export in the BY scenario are likely to expand until 2027, and there will be a sufficient amount of rice surplus for export, which is nearly the same level as that of domestic consumption in A2 scenario. In 2017, the amount of rice production will be only slightly higher than the domestic demand, leaving a small rice surplus of up to two million tons for export, compared to 14 million tons in 2016, will be created a loss in value approximately 5,280 dollar. However, in B2 scenario, the rice production capacity will be much lower than the domestic demand, meeting only half of it in 2017. From 2017 to 2019, the rice production capacity will undergo a constant fall and no longer meet the market demand as a result; it is estimated that there will be a shortage of approximately 0.038 to 0.218 ton of rice. It is therefore important to note that if B2 scenario became reality in 2017, the rice production capacity of Thailand would nearly fail to meet the minimum level of domestic demand. Our results point out that both A2 and B2 scenarios the amounts of rice production will be lower than those in the predicted BY scenario. The amounts of rice production in A2 scenario are higher than
those in B2 scenario in every region. Rice exports in both A2 and B2 scenarios will be lower than the volume of exports in the BY scenario while A2 scenario is higher than that in B2 scenario.
