Therefore, it is necessary to take into account the telecoupling among human social activities, environments, and biota while assessing the value of ecosystem services. In view of this, the Ministry of the Environment Government of Japan and the Institute for the Advanced Study of Sustainability proposed the “Satoyama Initiative” in 2010, which aims to seek biodiversity and human well-being. Afterward, an international partnership, named International Partnership for the Satoyama Initiative (IPSI), was found and acted as a platform to publish successful case studies on human well-being and biodiversity. The Gongrong community in Sanzhi District of New Taipei City is situated within the Balian River Basin and has been recognized one of successful cases by the IPSI since 2017. This community’s vision is to restore the “Socio-ecological production landscape (SEPL)” of the Balian River Basin, in particular, managing local ecological environments with the efforts of the community. This study takes the Balian River Basin as an example, and evaluates ecosystem values in the three aspects of SEPL in the Satoyama Initiative. On top of that, the Social Value of Ecosystem Services (SolVES) is used to determine 12 social values; ecological values are estimated by applications of the Integrate Valuation of Ecosystem Services and Tradeoffs Tool (InVEST), including annual water yield, sediment delivery ratio, carbon storage and habitat quality; the output-income per unit area calculation is applied to get production values through examining the relationship among unit output, total output and production area. Comprehensive evaluation results are standardized, summarized, and applied to compare spatial differences and similarities between values. Results of this study found that: (1) Communities with higher social values are concentrated in middle course and downstream of the river, such as in Baxian, Hongqiao, Fude, etc.; (2) Forest land in Yunshan has high ecological values, mainly with functions of evapotranspiration, more carbon capture and storage (CCS) and/or better habitat quality; (3) Higher production areas are situated near coastal line where growing sweet potato and strawberry. Particularly, after comparing both social and production values, it indicated that locations like Hongqiao and the farmer''s market exhibit higher social values than production ones, and the coastal upland are more valuable regarding production while social and production functions are equal important for the forest land of Yunshan. The comparison of ecological and social values suggested that the ecological value of forest land in Yuan Shan is higher than the social value. Hongqiao and the farmers market are with social values greater than ecological values, while paddy fields around Hongqiao and Farmers Market are weighed more for production than ecological functions. Regarding crossing evaluation of production and ecological values, it showed that coastal farmlands are with higher production value while the ecological value of forestlands in Yuanshan is greater than others. Moreover, middle course or downstream areas (e.g., Baxian, Hongqiao, farmer market in Fude) not only have the highest social value, but also paddy fields in neighborhoods are weighed equally important in terms of ecology and production. Therefore, SEPL values of this region present better equilibrium. This research makes a big breakthrough. Instead of going with traditional qualitative methods, it demonstrates that the Satoyama Initiative is an effective tool for achieving environmental benefits and human well-being, using qualitative approaches. The findings can also be referenced as a case study regarding evaluating three aspects of SEPL.
