Descriptive Method

Ekosistem mangrove memiliki fungsi fisik, ekologi, dan ekonomi bagi manusia. Pemanfaatan mangrove yang tidak konservatif dapat menimbulkan kerusakan mangrove dan abrasi. Pemulihan ekosistem mangrove dengan rehabilitasi dan konservasi dapat meningkatkan pendapatan masyarakat. Peningkatan pendapatan masyarakat ini mendorong diperlukannya perhitungan valuasi ekonomi terhadap ekosistem mangrove. Tujuan dari penelitian ini adalah mengetahui total use value dan non use value ekosistem mangrove di Desa Timbulsloko, Kecamatan Sayung, Kabupaten Demak. Metode yang digunakan dalam penelitian ini adalah metode deskriptif untuk menghimpun data monografi terkait ekosistem mangrove dan metode eksploratif untuk penentuan use value dan non use value ekosistem mangrove. Responden penelitian adalah 30 orang terdiri dari 29 masyarakat dan 1 orang perangkat desa yang berkaitan dengan keberadaan ekosistem mangrove secara langsung dan tidak langsung. Penelitian dilakukan pada Bulan September – Desember 2017. Hasil penelitian menunjukan nilai total ekonomi ekosistem mangrove di Desa Timbulsloko adalah Rp 164.897.377,1/ha/tahun atau Rp 12.703.693.939/ tahun dengan luasan ekosistem mangrove 77,04 ha. Nilai tersebut terdiri dari total use value dan non use value dari sektor perikanan dan kelautan yang terkait dengan ekosistem mangrove. Use value sebesar Rp 11.095.403.189/tahun atau Rp 144.021.329/ha/tahun. Use value meliputi nilai guna langsung, nilai guna tidak langsung, dan nilai pilihan. Sedangkan non use value sebesar Rp 1.608.290.750/tahun atau Rp 20.876.048,16/ha/tahun. Non use value meliputi nilai keberadaan dan nilai warisan.   Mangrove ecosystem has physical, ecological and economical functions for humans. Non conservative use of mangrove can cause mangrove damage and abrasion. Restoration of mangrove ecosystems with rehabilitation and conservation can increase community income. The increasing of community income can cause the need of economic valuation calculations for the mangrove ecosystem. The purpose of this study was to determine the total of use value and non-use value of the mangrove ecosystem in Timbulsloko Village, Sayung District, Demak Regency. The method used in this study was a descriptive method to collect monograph data related to mangrove ecosystems and an exploratory method for determining use value and non-use value of the mangrove ecosystem. The research respondents were 30 residents consisting of 29 communities and 1 village officer who were directly and indirectly related to the existence of the mangrove ecosystem. This researched was conducted in September – December 2017. The result showed that the total economic value of the mangrove ecosystem in Timbulsloko Village was Rp. 164,897,377.1 / ha / year or Rp. 12,703,693,939 / year in 77.04ha of mangrove ecosystem area range. This value consists of the total use value and non-use value from the fisheries and marine sector which associated with the mangrove ecosystem. The use value of IDR 11,095,403,189 / year or IDR 144,021,329 / ha / year. The use values include direct use value, indirect use value, and option value. Meanwhile, the non-use value is IDR 1,608,290,750 / year or IDR 20,876,048.16 / ha / year. The non-use values include existence value and bequest value.

Promoting forest as one of green economy asset in Indonesia become an important agenda in the process of development. Forests have an important role as a source of foreign exchange and also as a form of natural resource wealth. The era of globalization with the accelerated economic growth increases the need for both, the fields of agriculture, infrastructure, land requirements and other sectors. Increased human needs are giving a positive correlation to the increased pressure on forests. Mangrove forests as one of the most productive ecosystems in the world are also experiencing the same threat. The expansion of settlements and ponds in coastal areas lead to degradation of mangrove forests is very high. The economic value of mangrove forests of diverse functions such as shoreline protection, habitat for aquatic organisms, carbon storage, and a variety of other functions has not been a lot of concern to the public and policy makers. This study aimed to quantify the economic value of mangrove forests in Untung Jawa Island, Thousand Islands as an effort to support the government's program to realize the green economy in the forestry sector. Method of economic calculation mangrove forests in this research is to calculate the Total Economic Value / Total Economic Valuation (TEV), which consists of direct use values (Direct Use Value) and indirect use values (Indirect Use Value). The results showed that the direct use value of mangrove forests in Untung Jawa Island is Rp. 395,126,912 which includes the value of timber, fruit value, and the value of the fishery, while the indirect use value is Rp. 7,500,600,000 calculated from the value of coastal protection, the value of foraging, conservation value, educational value, and recreational value. The total economic value (total economic value) of mangrove forests in Untung Jawa Island reached Rp. 7,895,726,912Keywords : mangrove, green economy, total economic valuation

Passive Use Values

Valuation of ecosystem services (ESs) can be typical as use values and passive use values. However, the prevailing conventional markets provide economic instruments such as price tags to ecosystem use values, but rarely on passive use values. This is limited since it does not provide comprehensive ecological values that will adequately support rational decision-making processes regarding ecological conservation. The study adopted the contingency valuation method (CVM) where three hundred and eighty households of communities living within the Elgeyo watershed were sampled. The findings recorded 97% of the population was willing to pay for the ESs quoted. Individual maximum WTP ranged between 1 USD and 57.1 USD (cultural), 1 USD and 95.2 USD (bequest), and 1 USD and 76.2 USD (biodiversity conservation). The overall mean maximum WTP was 7.4 ± 0.34 USD, 9.1 ± 0.49 USD, and 11.1 ± 0.68 USD for the cultural, bequest, and biodiversity, respectively. The multivariate regression (maximum WTP as a function of administrative location, education, income, sex, age, and livestock number) exhibited a significant difference regardless of multivariate criteria used, where Wilks’ lambda has F (75,203) = 4.03, p < 0.001 . The findings provide an economic value for nonuse values that can be incorporated in total economic valuation (TEV) studies locally as well as provide an impetus on payment of ecosystem services (PES) in Kenya.

Mangrove ecosystems provide a wide range of market and non-market benefits to coastal communities in the developing world, yet they remain undervalued and overexploited in most regions where they are found. This paper analyzes the use and value of mangroves in Kosrae, Micronesia, where the population is largely dependent on the swamps for fuelwood and other ecosystem services, such as erosion control, storm protection, and nutrient flows to shoreline fisheries. The results show that mangroves on the island are worth between $666 thousand and $1 million per year (1996 prices) based on the net value of marketable products alone. In addition, household survey data suggest that the local people are willing to pay between $1 million and $1.26 million per year to protect and use mangrove swamps indefinitely. The results thus indicate that the population places some premium on the existence and indirect ecosystem services of mangroves, over and above the direct use values. Moreover, respondents generally favored—and were willing to pay more for—a tax system designed to manage and preserve the mangroves' direct and indirect services over a permit system focused only the allocation of direct use over time. Valuation analyses using revealed preference and contingent valuation methods lead to additional conclusions regarding the distribution of benefits, with poor households deriving more direct benefits from—but willing to pay less to protect—mangrove ecosystems.
