Outline of Final Research Achievements

The climate conditions such as the temperature affect the productivity of each crops and thus choice of crops, i.e. the land use. In this study I estimate the productivity models and land use model for each of 21 agricultural crops using the city-level panel data in Japan to explore the economic impacts of climate change on the Japanese agriculture sector. Our main findings are :(1)the temperature rise by 1 or 2 degree C increases productivity of land for rice, wheat, cucumber,egg plant, tomato, pepper, mandarin orange and grape and decreases that for the other crops in Hokkaido region. On the other hand, the rise decreases the productivity for all the crops to the west of Kansai area, (2)the land use for strawberry, apple, spinach and cabbage is decreased because of temperature rise,while that for rice, cucumber, mandarin orange, etc is increased
