- W2885142723 abstract "A paradigm shift in global trends for natural resources has supported the concept of ecosystem services (ES) for sustainable management. With increasing recognition of relationships between ecosystem functions and human activity, the concept of ES plays a crucial role in the identification of trade-offs between human well-being and ecosystem services. The newly established paradigm is based on an ecosystem approach to decision-making as reciprocity of environment-human linkages, unlike classical approaches for conservation, which feature unidirectional flow of benefit from ecosystems. The concept of ES highlights a holistic and integrated approach for sustainable ecosystem-based management. This underlines appreciation of whole ecosystem process and functions which contribute to human well-being and emphasizes multi-scale benefits of ES provided by tangible and intangible forms. However, a multidisciplinary approach for integrated ecosystem assessments has significant challenges to a pragmatic view of policy decision-making. Moreover, the concept of ES can be particularly useful as a policy instrument to reduce environmental pollution and degradation. Nevertheless, a lack of mechanisms for policy instruments in multi-scale approaches is a critical research gap and a lack of information about economic values for ES likewise remains an important knowledge gap in existing researches. This thesis aims at estimating the economic value of ecosystem services, focusing on water quality issues with specific applications such as drinking water supply. The papers attempted to reduce the aforementioned gaps by analyzing how benefits from ES influence the decision-making of both upstream farmers in farm management and downstream water consumers. With respect to the standing lack of information about economic valuation for ES in Asia (especially South Korea), this study focused on upstream regions (Gangwon Province) and downstream areas (Seoul, along South Korea’s Soyang watershed). As water quality degradation occurs by intensive agricultural production in the upstream area, water quality protection is essential for the preservation of a main drinking water source between upstream farm and downstream households. In the first paper, multinational logistic modelling was used to identify the key factors affecting farmers’ choices regarding the adoption of farming methods, based on interviews with conventional, partially converted and environmentally friendly farm households. In the second paper, contingent valuation methods were used to estimate the willingness to pay (WTP) for water quality improvement through the adoption of environmentally friendly farming. Lastly, in the third paper I used choice experiment method specifically stated preference techniques for the estimation of WTP based on three attributes: water quality, biodiversity levels and agricultural profits. The results from paper 1 showed that education level and subsidy positively and significantly influenced the probability of farmers’ choice on partially converted…" @default.
