Sustainability of mangrove forest management in the former bauxite mining area on Bintan Island

Abstract

Background : The bauxite mining area on Bintan Island continues to expand into the mangrove forest area. Mangrove forests have ecological, economic, and social importance, which must be managed accordingly to maintain their sustainability. This research was conducted to examine the sustainability of mangrove forest management in the former bauxite mining area on Bintan Island. Methods: The approach used is Multi Dimensional Scaling- Rapid Appraisal for Sustainability through the modified Rapfish ordinance software technique for the Mangrove Ecosystem. The type of data used is quantitative, covering five dimensions of sustainability, namely ecological, economic, social, legal and institutional as well as technology. Results: The results showed that the sustainability index status of the ecological, social, legal and institutional dimensions was quite sustainable, while the sustainability index of the economic dimension was unsustainable, and the technological dimension was less sustainable. Attributes of levers that are sensitive to the sustainability of mangrove forest management are: 1) Mangrove density, 2) Substrate fraction, 3) sedimentation, 4) Mangrove importance index, 5) Bio-concentration factor, 6) Benefit value direct, 7) Indirect benefit value, 8) Dependence on mangrove forest as a source of livelihood, 9) Corporate Social Responsibility funding support, 10) Community income, 11) Community health level, 12) Community perception, 13) Legality of mangrove area and mining, 14) Pollution monitoring technology in ex-mining areas and 15) Mangrove rehabilitation technology. Conclusions:The status of the mangrove forest sustainability index on Bintan Island is quite good. the economic and technological dimensions can be upgraded to sustainable status by carrying out management that is more focused on the lever attributes of the ecological, social, legal and institutional dimensions.
