Ecosystem service ES is a growing field of research characterized by an increase in publication number. The review was conducted to provide an overview of trends of forest ecosystem services FES research and methodological approach to studied FES.
Design and implementation of the modeling language and software: FV. Design and implementation of flow models: GJ FV. Ecosystem Services ES are an established conceptual framework for attributing value to the benefits that nature provides to humans. As the promise of robust ES-driven management is put to the test, shortcomings in our ability to accurately measure, map, and value ES have surfaced. On the research side, mainstream methods for ES assessment still fall short of addressing the complex, multi-scale biophysical and socioeconomic dynamics inherent in ES provision, flow, and use.
This is version 2. Ecosystems provide businesses with numerous benefits or "ecosystem services. River systems provide freshwater, power, and recreation. Coastal wetlands filter waste, mitigate floods, and serve as nurseries for commercial fisheries. However, human activities are rapidly degrading these and other ecosystems. The Millennium Ecosystem Assessment — the largest audit ever conducted of the condition and trends in the world's ecosystems — found that ecosystems have declined more rapidly and extensively over the past 50 years than at any other comparable time in human history.
A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize our current level of knowledge on the type and value of services provided by mangroves, discuss data gaps, and address specifically the collection of data relevant to cultural ecosystem services CES. Our results shed light on two principle issues affecting the mangrove valuation literature: overuse of benefit transfer in valuing mangrove ecosystem services and a lack of attention paid to the CES that mangroves provide. The mangrove valuation literature is not yet robust, lacking estimates of many ecosystem services, including CES, such as spiritual and aesthetic value. Most published studies focus on a small selection of ecosystem services based on the availability of benefit transfer values and the ability to easily measure values with market prices.
This study provides empirical evidence of the economic valuation of ecosystem services. A randomized conjoint analysis based experiment was conducted in seven villages of Sundarbans in Bangladesh to elicit stated preference data and measure WTP and CS. Each respondent faced three options in every choice card-two hypothetical alternatives and one status quo scheme. Four alternatives — payment for ecosystem services, storm protection, erosion control and habitat for fish breeding — are randomly and simultaneously assigned to the two alternatives. The findings suggest that age, income, education, family size and occupational status are the influential factor to choice the relevant attributes of ecosystem services and their levels. Villagers would like to pay annually Tk.
