Economic valuation of mangrove ecosystem environmental services based on green economy

Abstract

One of the important agendas in current development is promoting mangrove forests as one of the green economic assets in Indonesia. The green economy concept emphasizes improving people’s welfare but reducing the risk of environmental damage and scarcity of ecological functions. One approach that can be used to maintain economic activity and preserve the environment is the economic valuation approach. Therefore, this study aims to measure the value of the economic benefits of mangrove ecosystem services as one of the concepts of the green economy as an effort to support government programs to realize the mangrove ecosystem as a green economic asset in Indonesia. The economic valuation method used to calculate the mangrove ecosystem’s environmental services in Takalar Lama Village, Mappakasunggu District, Takalar Regency. The value of mangrove ecosystem environmental services calculated in this study is the value of abrasion resistance, the importance of preventing seawater intrusion, the value of crab feed providers, the value of carbon sequestration, the value of oxygen production, and the value of maintaining biodiversity. The results revealed that the value of the benefits of mangrove forest environmental services as a barrier to abrasion was IDR 32,457,189/ha/year or IDR 973,715,670/year, the value to prevent seawater intrusion was IDR 3,394.445,688/ha/year or IDR 101,833,370,640/year, the value of benefits as a provider of crab feed is IDR 544,320,000/ha/year or IDR 16,329,600,000/year, the annual carbon sequestration value is IDR 198,300.07/ha/year or IDR 5,949,002.1/year, the value of oxygen production is IDR 2,011,590/ha/year or IDR 60,347,700/year, and the value of biodiversity is IDR 637,376/ha/year or IDR 19,121,280/year so that the total value of environmental services for mangrove ecosystems based on green economics is IDR 3,974,070,143.1/ha/year (275,052.13 USD/ha/year) or IDR 119.222.104.292,1/year (8,250,663 USD/year).
