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.

Random Parameter Logit Model

Ecotourism can be an important tool for protecting biodiversity in developing countries. Tourists have preferences for viewing charismatic species and for their conservation, but our understanding of these preferences remains limited. Using choice experiment surveys, we investigate tourists’ preferences and willingness to pay (WTP) for the protection of the Ethiopian wolf ( Canis simensis) in Ethiopia’s Bale Mountains National Park. Results from a random parameter logit model show that tourists were willing to pay up to US$5.82/day/trip for increasing the wolf population from 200 to a more viable number of 250 but very little for a more substantial increase. Tourists also valued increases in the size of the protected area (PA) and access to the wolf habitat. The WTP is found to be dependent on tourists’ prior experience to Ethiopian PAs and whether they had viewed other unique species in the park. The findings suggest opportunities for ecotourism to support the Ethiopian wolf, which is in a critical state, and that the primary motivation for tourists’ support might be due to the wolf’s existence value.

Benefit Cost

AbstractSince its introduction to the field of environmental and natural resource economics in the late 1960s, existence value has faced several critiques from economists, psychologists, and philosophers. Critics have taken aim at the notion’s conceptual ambiguity and lack of connection to observable behavior, its incompatibility with cognitive processes and its sensitivity to cognitive biases, and ethical shortcomings in applying existence values to environmental decisionmaking. Unlike some critiques of existence value that draw on cognitive and ethical frameworks for decisionmaking fundamentally at odds with stated preference methods and benefit–cost analysis (BCA), this paper takes as given the use and adequacy of both. It focuses on challenges to existence value per se, with respect to the ability of existence value estimates to contribute to benefit–cost analyses in a way that is consistent with qualities of BCA that its proponents value: the objectivity, commensurability, and moral salience of the values analyzed. In light of the challenges, inclusion of existence value in benefit–cost analyses is found to inevitably compromise the quality of the BCA with respect to each criterion.

Globalisation is a key pressure affecting the current and future use of the rangelands of Australia. While primary producers often perceive an insatiable demand for food as a guarantee of business success, declining population growth rates and high levels of productivity improvement in world food production are reducing the importance of food and fibre from the rangelands. This, combined with significant changes in consumer demands, is driving rangeland producers to meet market specifications for quality, safety, animal welfare and sustainability. Sustainability is a particular challenge with the rangelands certain to be affected by global warming and the politics and strategies required to reduce greenhouse gas emissions. Currently the rangelands produce a higher proportion of greenhouse gases compared with their contribution to the economy. However, they also provide an opportunity for carbon sequestration. While international trade liberalisation has been of advantage to the grazing industries in the rangelands, increased global awareness of the Australian rangelands, facilitated by the communications revolution, is encouraging alternative uses including tourism, existence value and other conservation and biodiversity management uses. The growing concept of multi-functionality will also impact on the rangelands as international government programmes continue to encourage non-commercial, surplus production of food. These influences are forcing major changes in the way land is used and what it produces.
