Zusammenfassung
It is now well understood that the global warming will affect the agricultural production through the changes of ecological systems and the damages of land by sea-level rise, although the warmer climate and the higher concentration of CO2 contribute to the photosynthesis of the crops due to the potential loss of cropland and the precipitation change. High temperature damage on the rice production should also be taken into account. While many assessment investigations on the food supply potential have been developed, few have achieved the food demand considering the changes of dietary issues. This study aims at the assessment of the future demand-supply interactions under the future global warming using GIS. The current study shows us that although the global warming could contribute to the world food production, the negative impacts will appear in the developing regions and thus both the land and water management issue and the distribution of food issue will become more important.
