Abstract
Establishing " Low carbon society " on large cities as well as numerous small cities is important for global climate change. On the other side, the Japanese forestry industry has been significantly affected by increase in low-price timber imports and short of work force. These reason cause poor maintenance of the coniferous forests. In this paper, sustainable heat energy supply system for hothouse cultivation is examined by considering proper man-made forest management plans. It is estimated that 161% of energy demand of hothouse cultivation can be supplied from man-made forest with sustainable management on case our study area, Inami town, Wakayama prefecture, Japan.
