Outline of Final Research Achievements |
The purpose of this research is to evaluate regional impacts of a green tea food system under climate change in Japan using a multi-regional Computable General Equilibrium (CGE) model. An econometric analysis showed that abnormal weather conditions caused different damage to the productivity of tea leaf production in each region: negative weather conditions included the annual duration of sunshine and abnormal high temperatures in summer in Kyusyu and the average annual temperature and drought conditions in Kanto. It also revealed that tea cultivar diversity contributed a positive impact for tea leaf production in Kyusyu. Furthermore, the result of a simulation in the multi-regional CGE model showed the impact of abnormal weather conditions in a specific region such as Kyusyu multiplied damage to each regional green tea food system through the supply-chain of intermediates. At the same time, cultivar diversity contributed to moderate these damages.
