Coastal areas can either meet the human needs or give great contribution to the development. However, rapid infrastrural development in Sorong, west Papua, has been followed by high demand for mangrove timber and caused mangrove forest degradation due to exploitation. This exploitation could also result from high economic value of the mangrove timber. This study was done to analyze the economic value of mangrove wood utilized by the people to support the development process in Sorong. This study used primary data obtained through interviews and the economic value calculation of mangrove forests. It found that Sorong had mangrove economic value of IDR 165,197,833, 491. Wilayah pesisir selain dapat memenuhi kebutuhan hidup manusia juga memberikan kontribusi yang besar bagi pembangunan. Cepatnya pembangunan infrastruktur di Kota Sorong diikuti pula dengan tingginya permintaan akan kayu mangrove dan menyebabkan terjadinya degradasi hutan mangrove akibat eksploitasi.

Policy Scenario

Mangroves provide benefits and various services to local communities living along coastal areas, particularly fishery communities. Fishery community perceptions are significant in determining attitudes towards improving mangrove conditions, which can also be addressed through restoration activities. This research was conducted to analyze fisheries communities perceptions, willingness to pay (WTP) for mangroves restoration, and mangrove forest management strategies. Field surveys were conducted from July-August 2019 and February-March 2020. Primary data were collected from respondents in four regions (Kalianda Regency, South Lampung Regency, Bandar Lampung City, and Pesawaran Regency) in Lampung Province, Indonesia, which consist of fishers, shrimp farmers, crab and wood seekers, and finfish farmers. The respondents were 193 people, and four experts were involved in the policy scenario analysis. Results revealed a gap in the value of WTP among fishery community groups, in which the average value for fishers is lower than shrimp farmers. The years of formal education significantly influenced the WTP for mangrove restoration. Based on the scenario analysis, scenario 01 become a priority strategy, where four policies (P1 = Mangrove ecotourism development in Lampung Bay; P2 = Mangrove knowledge education and training on processing mangrove based products; P3 = Restoration and conservation of mangrove forests; and P4 = Community-based management for mangrove forests utilization) show high likelihoods to be simultaneously implemented for mangroves management, with mangrove ecotourism policy as the most decisive policy. For future research, other explanatory variables can be added, such as information on family member characteristics, and to develop a bottom-up policy scenario by identifying and involving the role of the local community.

The study analyses anthropogenic influence on the mangrove forests of the Cameroon coast and focuses on the development and improvement of the constructive- geographical foundations of rational nature management for the conservation and possible renewal of its natural resources base. The exploitation of mangrove forest landscapes has yielded significant benefits to the local population living within the mangrove forest limits, but the beneficiaries have not made commensurate investments in their sustainability and rational use. Therefore, this habitat must be carefully conserved or protected from wanton anthropogenic activities for the development purpose. The study made use primary and secondary data in establishing the facts analysed in this work. The secondary data comprised of materials of prominent authors who have contributed much to the findings related to coastal mangroves. Primary data collection was field visits carried out by the author in 2016. Questionnaires and semi- structural questions were used to collect information from mangrove exploiters. The findings confirm that the coastal mangrove forests in Cameroon have multiple functions beneficial to the communities adjacent to the coast, but, unfortunately, the beneficiaries have not made commensurate efforts to their sustainability and rationale. The Mangrove forests covered a surface area of 200 000 km2, but Cameroon lost 30 % of its mangrove forest cover in 1980–2006. If projected under ceteris paribus, Cameroon lost approximately 45 % of its mangrove forest cover in1980–2020. Haven understood that man has raped huge surfaces of mangrove forest for his selfish economic gains, the study proposed an urgent need for environmentally sustainable adaptive strategies like those earmarked in the Ramsay agreement and the ICZM (Integrated Coastal Zone Management) for the rational management of coastal mangroves in Cameroon.

Ekosistem mangrove mengalami tekanan dan penurunan jasa lingkungan diduga karena abrasi dan fenomena alam serta aktivitas masyarakat seperti penggalian pasir di pesisir pantai. Pemerintah telah melakukan upaya konservasi hutan mangrove dengan cara penanaman kembali, namun belum berhasil. Salah satu permasalahan adalah belum atau tidak adanya informasi nilai ekonomi mangrove sebagai dasar penentuan program konservasi. Penelitian ini bertujuan mengetahui nilai ekonomi ekosistem mangrove di pesisir Laut Arafura meliputi 3 distrik yaitu Malind, Merauke dan Naukenjerai. Metode yang digunakan yaitu TEV (Total Economic Value) yang terdiri dari analisis nilai guna langsung menggunakan harga pasar. Nilai guna tidak langsung dan nilai pilihan menggunakan benefit transfer. Nilai non guna yang terdiri dari nilai keberadaan dan nilai pewarisan menggunakan WTP (willingness to pay). Hasil penelitian menunjukkan bahwa nilai ekonomi hutan mangrove di kawasan pesisir pantai Laut Arafura per tahun sebesar Rp. 213.344.656.759,00 (213 Milyar Rupiah) atau setara dengan Rp. 21.075.240,00/ha/tahun atau setara dengan Rp. 8,6 juta rupiah per kepala keluarga. Title: Economic Valuation In The Coastal Mangrove Ecosystem District MeraukeEcosystem mangrove in Araufra Coastal had underpressure and decreasing environmental services because of abration as natural phenomena, and unsuistainable community activities such as digging sand on the coast. The Government has made the conservation of mangrove forests by replanting, but has not succeeded. One of the problems is not yet or absence of information about the economic value of mangroves as the basis for determining the conservation program. This study aims to determine the economic value of the mangrove ecosystem in the Arafura Sea coast in three districts: Malind, Merauke and Naukenjerai. The methodology using TEV (Total Economic Value) consisting of direct use value analysis using market prices. Indirect use values and the options value using the benefits transfer. Non-use value consist the existence and bequest value using WTP (willingness to pay). The result showed that the economic value of mangrove forests in the coastal regions of the Arafura Sea is Rp. 213.344.656.759,00 (213 billion rupiah per year) or equivalent with Rp. 21.075.240,00/ha/year, or equivalent with Rp. 8,6 million per household.

Sylva Untan Arboretum has high biodiversity. However, these values and benefits are not yet known by many parties, hence the existence of the Sylva Untan Arboretum could be changed. The purpose of this study was to determine the economic value of the Sylva Untan Arboretum. The study was conducted using a survey method. Primary data was collected through observation and interviews, while secondary data was collected from various literature. The economic value was calculated using three methods, namely the market price method, substitution cost method, and contingency method. The data were analyzed using an analysis of total economic value. The results showed that the economic value of Sylva Untan Arboretum was IDR 15.346.872.680 per year. Economic value in the form of service benefits (intangible) was higher than the tangible value. The measurement of the economic value of Sylva Untan Arboretum can be done using other approaches and methods that are more holistic as a comparison of existing economic values especially for several values, such as biomass value, water absorption, and land rent. The measurement of the economic value of the Sylva Untan Arboretum needs to be developed to make a positive contribution to the people living around it, as well as decision making in land use.Keywords: arboretum, benefit, ecosystem, economic valuation
