Abstract. Authors. 2019. Economic valuation of the Danau Sentarum National Park, West Kalimantan, Indonesia. Biodiversitas 20: 1983-1989. The Danau Sentarum ecosystem in West Kalimantan, Indonesia is officially protected by its status as an Indonesian national park. Nevertheless, it remains under severe threat of deforestation. Rainforest destruction has already caused a decline in ecosystem functions and services. In addition, it is affecting numerous economic activities in and around the Danau Sentarum National Park. The objectives of this study are to determine the total economic value (TEV) of the Danau Sentarum National Park and look for appropriate mechanisms to realize such values. Survey methods were used in this research. 180 respondents were selected by random sampling method from three Management Section National Park (MSNP). TEV in this research was restricted on direct use value, indirect use value and option value. Estimation of DSNP ecosystem benefits was approached by market price, travel cost method, contingent valuation method, and opportunity cost adjusted for the benefits calculated. The direct use value of Danau Sentarum National Park is IDR 18.5 billion/year while the indirect use value of Danau Sentarum National Park is IDR 34.2 billion/year. The option value of Danau Sentarum National park is IDR 86.2 billion/year. The total economic value resulted in Danau Sentarum National Park is IDR 139,1 billion/year, equivalent to an average of IDR 1.1 million/year for the total park area (132,000 ha). When compared to the TEV of the DSNP, such costs amounted to only 4.87 percent compared to the value of the benefits Based on monetary values of ecosystem services that are provided by this park we could assess the mechanisms to finance the park’s conservation and sustainable use. This will help the self-management of national parks.

Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y, Ma’ruf A. 2020. Fauna diversity, production potential and total economic value of mangrove ecosystems in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 21: 1940-1953. Mangroves play important role in life. The benefits of the mangrove ecosystem consist of ecological and socio-economic values. However, it is a challenge to discern how the mangrove ecosystem provides a comprehensive economic value. This research is aimed to analyze the Total Economic Value (TEV) of mangrove ecosystems in Mentawir Village, North Penajam Paser District, East Kalimantan Province. This aim will be achieved by conducting fauna inventory, analysis of mangrove wood production potential, social-economic interviews, and infrastructure cost analysis as the inputs to calculate four elements (i.e. Direct Use Value, Indirect Use Value, Option Value, and Existence Value) to sum up the TEV. The research used a mixed-method combining both qualitative and quantitative methods. Fauna inventory was conducted using boat survey method and interviews with local fishermen. Data on mangrove wood production was obtained using the systematic random sampling method by establishing two plots with an area of one hectare for each plot to calculate mean annual increment (MAI) and current annual increment (CAI). The economic value of the mangrove ecosystem was calculated using market price values, replacement costs, and the Contingent Valuation Method (CVM). The results of fauna inventory consisted of 3 species of mammals, 1 species of reptile, 16 species of birds, 25 types of fish, 8 species of crustaceans, and 7 species of mollusks. The economic valuation resulted in the contribution of direct use value with 39.56% in the form of wood (94,875,000,000 IDR) and fishery products (103,500,000,000 IDR); indirect use value with 53.47% in the form of breakwater (38,028,881,407 IDR), abrasion resistance (218,549,528,110 IDR), and carbon sequestration (11,580,313,067); option value with 6.92% in the form of biodiversity (34,690,085,038 IDR); and existence value with 0.05% (241,500,000 IDR). All these resulted in the total economic value (TEV) of the mangrove ecosystem in Mentawir Village of 501,465,307,621 IDR. Therefore, this value can be the basis for policymakers in managing natural resources so that the ecosystem is more protected and sustainable, and can continue to provide environmental services for the welfare of the community.

-The case study examines the economic aspects of cultural heritage conservation and deals the valuation of economic value in monetary terms, using the application of the contingent valuation method to the castle of Nicastro (Catanzaro, Italy). For the construction of the hypothetical market and the selection criteria and approach to subjects of the statistic sample, the proposed solutions work with operative adjustments, dictated by the characteristics of the resource in question and in general for all cultural resources. The study has produced reliable answers to questions of willingness to pay, expressing the measure of the different components of the value (use value and existence value) contribute to the composition of the total economic value. The study allowed to verify the possibility of using the contingent valuation as a political tool. The particular question format, which combines ‘double bounded dichotomous choice' and ‘open ended' techniques has allowed us to take a sensitivity analysis, defining the measure of willingness to pay.Key words: evaluation cultural resource, contingent valuation method, willingness to payParole chiave: valutazione, beni culturali, metodo di valutazione contingente, disponibilitŕ a pagare

Roslinda E, Kartikawati SM, Rabudin. 2017. Economic valuation for tembawang ecosystem, in Sanggau District, West Kalimantan, Indonesia. Biodiversitas 18: 1506-1516. The tembawang ecosystem in West Kalimantan (Indonesia) spreads over especially in Sanggau District region. Tembawang is a system of land used by customary community of Dayak ethnic which is traditionally managed and communally used. The objective of this study is to determine the total economic value (TEV) of the tembawang ecosystem. Survey methods were used in this research. 70 respondents were selected by census method. Total economic values in this research were restricted on direct use value, indirect use value and option value. Based on market price (biomass) and opportunity cost (hydrological role), the economic values were calculated. The results showed that total economic value of Tembawang Ampar was IDR 263,837,082 year-1, which was equivalent to IDR 36,900,291 year-1ha-1. They are IDR 33,545,791 year-1ha-1 from direct use value, IDR 3,072,738 year-1ha-1 from indirect use value, and IDR 281,762 year-1ha-1 from option value. Total economic value of tembawang was rather low. The low of economic value was due to limited benefits assessed in this study. Whereas in fact, there were many benefits from tembawang obtained by the community. Conserving tembawang ecosystem will not be achieved by simply considering the conservation of species in tembawang, but the preservation will need to encompass a wide range of natural resources and the potential services provided by them.
