Two-Stage DEA of 122 Paddy Fields in Hokuriku Region

In Japan, rice production is undergoing a transition from acreage reduction to an improvement in efficiency and competitiveness. Owing to the global warming, irrigation management is increasingly important in maintaining soil temperature and fertility for rice productivity. This chapter aimed to measure the production efficiency of rice yield, using a two-stage DEA like the former chapter. The data comprised of 122 paddy fields of Koshihikari, one of the most popular Japanese rice varieties. The data was sampled from a large-scale farm located in the Hokuriku Region of Japan in 2015.
