エネルギー自立性を高める新里山システム

抄録

A folky mountain system (“Satoyama” in Japanese) has a peculiar feature in the view of energy system. In Japan, many of the forests exist in such steep mountains, that the large expense is needed for the collec-tion and transportation of the felled or thinned woods. On the contrary in folky mountains, we can expect to avoid the big energy loss at the process of transportation because of the short distance to the consumers. However, the folky mountain system nowadays is declining because of an aging of the laborers and subsid-ence of demand of fuelwood. Accordingly, the restoration of classical folky mountain system is quite diffi-cult without new system-tool. We proposed here several new measurements to solve the Problems: (1) rental forest, (2) household forest, (3) mountain-forestal pasture, (4) thinned wood direct use.
