海洋保護区（MPA）管理の「コモンズのコスト」論的分析¹⁾

―フィリピン・ビコール地方の3つのMPAの比較―

抄録

We describe the characteristics of 3 MPAs around the Lagonoy Gulf in Bicol Region, the Philippines. We analyze and compare them from the viewpoint of the “Cost of Commons.” We find that 1) in order to manage an MPA properly, it is important that it is sized and shaped appropriately, 2) community-based management is effective, because fisherfolk can help monitor the MPA, 3) while state-management enjoys the advantages of budget availability and partnership between the police and government, it is disadvantageous due to the lack of partnership with the local people, and 4) new MPA management that combines the merits of both management approaches is being tried in Tabaco and Atulayan.
