Carbon storage and sequestration is one of the most important services provided by forest ecosystems, the most powerful tools for climate change mitigation and adaptation. Its value is not always captured and appreciated at a fair level, with people taking for granted these benefits provided by the ecosystems. Our first objective was to evaluate the amount of carbon storage and sequestration within a specific area—Retezat National Park (RNP), Romania, in a specific timeframe, using mainly the data from forest management plans. The second objective was to estimate the economic value of the carbon sequestered by the ecosystems within the national park. Based on the carbon market price, we calculated the monetary value of the sequestered carbon. The third objective was to cross-validate the model using mobile terrestrial LiDAR scanner 3D mapping technology in several field plots. Our results reveal comparable stocks of carbon with the ones modelled based on the forest management plans, enabling us to use these plans as an accurate source of information. The present study underlines that the financial effort for the management of the ecosystems which provide these services can be sustained by implementing financial mechanisms aiming to direct ecosystem services values into the management of these ecosystems.

Muara Angke merupakan satu – satunya kawasan yang masih memiliki ekosistem mangrove di daerah pesisir Jakarta. Luas Muara Angke kurang lebih 964,98 ha dibagi menjadi tiga zona. Dua diantaranya berkontribusi pada sektor Perikanan dan Ekowisata, yaitu Pangkalan Pendaratan Ikan (PPI) dan Taman Wisata Alam Angke Kapuk (TWAAK). Kurangnya pemahaman umum tentang manfaat ekonomi ekosistem mangrove  menyebabkan masyarakat mengeksploitasi secara berlebihan sehingga terjadi perubahan penggunaan lahan. Tujuan penelitian ini untuk mengetahui nilai ekonomi yang dihasilkan ekosistem mangrove berdasarkan dua aspek yaitu Perikanan Tangkap dan Ekowisata. Data Perikanan Tangkap menggunakan data sekunder dari Pengelola PPI Muara Angke tahun 2016 – 2017. Data sosial ekonomi diperoleh menggunakan  wawancara dengan bantuan kuesioner. Data biaya perjalanan rata – rata diperoleh dengan wawancara pengunjung TWAAK. Analisis Valuasi Ekonomi Perikanan Tangkap menggunakan Market Price Method. Analisis Valuasi Ekonomi Ekowisata Mangrove menggunakan Travel Cost Method. Metode penentuan 100 responden nelayan tangkap menggunakan Random Sampling sedangkan penentuan 100 responden pengunjung TWAAK menggunakan Accidental Sampling. Hasil penelitian didapatkan nilai ekonomi pada aspek perikanan tahun 2016 Rp. 13.148.945.100, tahun 2017 Rp.21.087.388.300 dan tahun 2018 Rp. 370.313.869.500. Hasil penelitian didapatkan nilai ekonomi ekowisata tahun 2018 Rp.40.28.400.000 Muara Angke is the only area that still has mangrove ecosystems in the coastal areas of Jakarta. Muara Angke area is approximately 964.98 ha divided into three zones. Two of them contribute to the Fisheries and Ecotourism sector, namely Fish Landing Base (PPI) and Angke Kapuk Nature Park (TWAAK). Lack of general understanding of the economic benefits of mangrove ecosystems causes people to over-exploit so that land use changes occur. The purpose of this study was to determine the economic value generated by mangrove ecosystems based on two aspects, namely Capture Fisheries and Ecotourism. Capture Fisheries Data uses secondary data from Muara Angke PPI Manager in 2016 - 2017. Socio-economic data were obtained using interview with Muara Angke fishermen with questionnaire assistance.

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.

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

Important Challenge

An important challenge of integrated water resources management (IWRM) is to balance water allocation between different users. While economically and/or politically powerful users have well developed methods for quantifying and justifying their water needs, this is not the case for ecosystems—the silent water user. A promising way of placing aquatic ecosystems on the water agenda is by economic valuation of services sustained by ecosystems. In developing countries, the livelihoods of rural people often depend directly on the provision of aquatic ecosystem services. In such situations, economic valuation of ecosystem services becomes particularly challenging. This paper reviews recent literature on economic valuation of aquatic ecosystem services in developing countries. “Market price” is the most widespread method used for valuating marketed ecosystem services in developing countries. “Cost based” and “revealed preference” methods are frequently used when ecosystem services are non-marketed. A review of 27 existing valuation studies reveals a considerable range of estimated total economic value of aquatic ecosystem services in developing countries, that is from US$30 to 3,000/ha/year. The paper concludes that economic valuation is vital for bringing ecosystems to decision-making agendas in developing countries and that great effort must be made to bridge the gap between scientists and decision makers.

Abstract. Sondak CFA, Kaligis EY, Bara RA. 2019. Economic valuation of Lansa Mangrove Forest, North Sulawesi, Indonesia. Biodiversitas 20: 978-986. Mangrove forest gives many benefits and services to human and environment. Even though it contributes many benefits and services, coastal ecosystems threatened as one of the most critical ecosystems in the world. The study aims to estimate the economic value of ecosystem services provided by Lansa mangrove forest, Wori Sub-district, North Minahasa District, North Sulawesi Province, Indonesia. Here, we describe the use value (direct and indirect value) and non-use value (option and existence value), and emphasize the components of ecosystem services fish resources, firewood, coastal protection, biodiversity, carbon (C) removal and mangrove sustainability because these directly influence human welfare. Their market price calculated fish and C removal value. Coastal barrier and firewood were approached using the replacement cost method. Biodiversity value was calculated using Indonesia mangrove forest biodiversity value. Contingent Valuation method was used to find out people willing to pay for the sustainability of mangrove forest. Lansa mangrove forest total economic value (TEV) was IDR 4,431,197,603 or equal to US$ 305,600 (US$ 1,959 ha-1). The success of this mangrove valuation has potentially large implications for future policy-making of its’ ecosystem service values.

: This paper aims at analyzing whether existing economic value estimates for forest ecosystem services (ES) might be transferred and used for valuation purposes elsewhere, and whether these data are appropriate for application in forest management. Many forest ES are public goods or positive externalities, and as a consequence they do not have a market price. The valuation of forest ES can provide important information for decision making in forest management and planning as well as in political processes, especially by allowing the comparison of different alternatives and helping set priorities for practical actions, as well as developing financial incentives or support mechanisms. We analyze whether an integrated economic valuation model for forest ES can be developed based on existing published data. To achieve this, we assess to which extent a benefit transfer could be expedient, and which challenges must be addressed. Based on a literature search, we compiled an extensive database of forest ES values. Given that these values vary substantially for the same ES, such a database alone does not seem useful to serve as a decision and management support tool. In addition, the available information mainly focuses on forests as such, and does not include desirable forest composition and management targets. If existing estimates should be transferred and used for forest management decisions, both the background conditions of the primary studies and the indicators used for valuation need to be specified in detail. The most expedient approach in this context seemed to be a valuation function transfer based on a broad set of indicators, offering the possibility to adapt the valuation function to changing background conditions.
