Mangrove ecosystems have multiple functions, including economic and environmental ones. For optimal benefits, mangrove ecosystem management should be well-proportioned. The purpose of this study was to determine the most appropriate scenario for managing a mangrove ecosystem alongside aquaculture ponds, by performing an economic valuation to find out the value of management with the most beneficial scenarios, both ecologically and economically. Data were collected through interviews using questionnaires, literature reviews, and institutional data. These data were then processed through economic valuations of the total economic value and cost-benefit analysis. Data were analysed spatially and descriptive-quantitatively. The total economic value of the mangrove ecosystem was USD 6.73 million. The benefit and costs of managing mangrove ecotourism were USD 3,930.74/ha/year and USD 1,701.69/ha/year, respectively, whereas the benefits and costs of managing ponds were USD 150,433.85/ha/year and USD 55,269.46/ha/year, respectively. The prioritized scenario of mangrove ecosystem management is one with an ideal proportion of mangrove and pond areas (i.e. 50:50) and the total ecological and economic benefits for a period of 25 years is USD 19.17 million.

Method Analysis

Mangrove ecosystem is a very important resource for the continuity of community life in coastal areas. Mangrove ecosystem in the coastal area of downstream Rokan district has decreased mangrove area because it is used as a pond area to reduce the production of mangrove litter as an ecological function that can be a carrying capacity of coastal capture fisheries. However, the use of coastal areas as pond areas provides economic benefits for aquaculture. This study aims to calculate the economic value of the Rokan Hilir Coastal mangrove ecosystem. This research was conducted in March-April 2019 in the survey method. Analysis to calculate the total economic value of the mangrove ecosystem is NET=ML+MTL+MP. The results showed the total economic benefit value of Rokan Hilir mangrove forest reached IDR 98.697.950.594 / year was a direct benefit value of IDR 701,425,106 / year, indirect benefits were obtained at IDR 94,606,056,000 / year, and the optional benefits reached IDR 3,512,126,520 / year. Mangrove ecosystems are ecosystems that provide many benefits to the Rokan Hilir Coastal community, so this ecosystem is highly expected to be sustainable.

Green facilities of urban agriculture offer a fertile ground for green innovation, such as rooftop gardens, green curtains, and indoor plant growing, which create a new forms of urban farming economy. The previous studies for cost-benefit analysis of urban agriculture indicated that green facilities could contribute both quantitative and qualitative benefits. The value of green facility strategies of urban agriculture may often be underestimated without transforming qualitative benefits to quantitative benefits. This study examined the effects of green facilities of urban agriculture development in Taiwan. The market reaction was explored by adopting economic value added (EVA) technique for the measurement of both quantitative and qualitative value contributed by green facilities. The results from this study support that there exists interaction between qualitative factors such as indirect economic benefits and social psychological benefits and quantitative factors, agricultural production and energy saving impacted by green facilities. The study concluded that consumers of urban agricultural crops are willing to pay more for eco-friendly products. The establishment of relationship between urban agricultural production and consumption can contribute to sustainability while generating economic opportunities.

ABSTRACTThis paper applies a household production framework (Becker, 1971) to infer the economic value of a cultural heritage site, namely, the Petroglyph National Monument, situated in Albuquerque, New Mexico, USA. The empirical analysis uses benefit-transfer techniques from three source studies: those of Bergstrom and Cordell (1991) and Boxall et al. (2003), which concern willingness-to-pay to hike and view rock art sites; and those of Rolfe and Windle (2003, 2006), which concern willingness-to-pay by Aboriginal and general populations to preserve a cultural heritage site containing rock art. The benefit-transfer analysis estimates recreational values between 3.75 million and 7 million dollars per year (depending on perceptions of the cultural attribute quality) and a nonuse value of approximately 12.5 million dollars per year. By comparison the annualized costs of developing/operating the study site are 8.5 million dollars per year. Thus a partial cost-benefit analysis suggests the study site yields net economic benefits upwards of 7.8 million dollars per year.

Most ecosystem services are regarded as free goods (i.e., priceless). This paper estimates monetary value of the ecosystem services after renaturalizing the navigation channel in the Kreetsand’s area along the tidal section of the Elbe River. The river channel is basically reconnected to its floodplain which is currently grassland. The paper used benefit transfer method whereby values from previous studies are adopted to estimate total economic value of the ecosystem services provided by the study area. The results show that total economic value of the ecosystem services flow at the Kreetsand’s shallow water area is €0.83 million/year. Nevertheless, the value seems to be underestimated due to errors inherited during valuation. After 44 years, the value will accumulate to €36.5 million, which is equal to the project investment cost estimated to be around €36.6 million. Based on the cost-benefit analysis results for the project, it is concluded that river renaturalization is the best option because it increases ecosystem services flow. The paper recommends that a similar study should be conducted to include more ecosystem services and ecosystem goods such as fish and water used for industrial purposes.
