民間の支援手法による環境保全の検討

Abstract

Akiyoshi-dai karst plateau is the largest limestone plateau in Japan. Its grassland which has been used as a meadow or cultivation land is a secondary nature and it has been providing ecological services such as functions of biodiversity conservation，the rural economy through tourism，education through nature leaning for next generations. This study examined non-public funded measures for the maintenance and estimated the value of Akiyoshi-dai grassland conservation using CVM. From the estimation results of 460 yen as WTP，we could secure enough funding for maintaining conservation activities. Also，when people have more knowledge about farmers still using the green manure from Akiyoshi-dai grassland; want to come back with other visiting purposes; are willing to volunteer conservation of plateau; and also have more knowledge that active conservation can avoid the grassland degradation，we can secure necessary budget sufficiently. Therefore，we shed light on securing sustainable funding in the paper and the local overnment can put efforts on such aspects of advocacy.
