“…The literature shows that such tasks have been conducted using stated preference techniques, including CV (e.g., [7][8][9][10][11]) and choice experiments (e.g., [12][13][14]). On the other hand, Camacho-Valdez et al [15] generate baseline estimates of the ecosystem services provided by wetlands using value transfer approach. Ruitenbeek [16] used a market value approach to value a mangrove.…”

Abstract:The Saemangeum open sea (SOS), which refers to the outer sea of the Saemangeum seawall in Korea, is being threatened by contamination caused by the Saemangeum development project. The policy-makers need information on the environmental conservation value of the SOS for informed decision-making about the SOS. This paper attempts to measure the environmental conservation value of the SOS. To this end, the public's willingness to pay (WTP) for conserving the SOS is derived from a 2015 contingent valuation survey of 1000 Korean households comprising 400 households residing in the Saemangeum area and 600 households living in other areas. The authors employ a one-and-one-half-bounded dichotomous choice question format. Moreover, the spike model is adopted to analyze the WTP data with zero observations. The mean annual WTP values for both areas are calculated to be KRW 3861 (USD 3.26) and KRW 3789 (USD 3.20) per household, respectively. They are statistically significant at the 1% level. When the sample is expanded to the whole country, it is worth KRW 70.9 billion (USD 59.8 million) per annum. Therefore, conserving the SOS will contribute to the Korean people's utility and can be done with public support. The value provides a useful baseline for decision-making for the SOS management.

Wetland, an important ecological system, has irreplaceable ecosystem service value. The area of natural wetland decreases rapidly in recent years [1] [2] [3]; the study on ecosystem service function of wetland becomes a hot topic. Wetland system is a complicated natural system. However, in past several decades, people unilaterally emphasize the function and composition of wetland ecosystem or studied as a whole. It becomes a question to study its ecological function with system theory. So, in this paper, the system theory is an integral theoretical basis to study water requirement of wetland ecosystem. We build a dynamic balance with water requirement of ecology to get the balance equation about wetland system of the ecological water requirement. Then the ideal model is defined as the best function of wetland ecosystem based theory above. The model could avoid the repetition of the different water requirement. In the end, we discuss the application of the model under different management objectives and the best control model. The ideal model could be used for managers to estimate the health of wetland ecosystem, look for the reasons and restore them.

“…Coastal lagoons are receiving increasing attention worldwide in recognition of their multiple uses and services (Elliott, 2011;Basset et al, 2013a;Camacho-Valdez et al, 2013), but also because of their fragility to the synergistic effect of climate change (CC) and human pressure (Anthony et al, 2009;Tagliapietra et al, 2011;Basset et al, 2013b). For instance, CC-related variation in timing and quantity of wet deposition may alter the runoff and river hydrology, with effects on freshwater and nutrient delivery to coastal lagoons, and nutrient stoichiometry within lagoons (Cossarini et al, 2008;Padedda et al, 2012).…”
