Effect of different personal histories on valuation for forest ecosystem services in urban areas: A case study of Mt. Rokko, Kobe, Japan

This study investigated the effect of valuators' personal history and beliefs on valuation of ecosystem services around Mt. Rokko, which is located near Kobe, a major city in Japan. Special attention was paid to how differences in lifestyle, access to nature, and experiences during childhood influence willingness to pay (WTP) for peri-urban ecosystem conservation. The estimated values (median: 1858 JPY) were relatively higher than in previous case studies including one on the World Heritage forest in the country, but the value was not outlier of the literature. From the simple model estimation, we focused on the effect of individual differences. The full model including information of personal experience with nature revealed differences in WTP among residents. The basic characteristics of age and income were found to have a significant effect. Interestingly, it was also found that certain experiences during childhood had a significant effect on increasing WTP for ecosystem and biodiversity conservation. These findings suggest the importance of considering the diversity of valuators in ecosystem valuation studies under urbanization processes, and it also warns the extinction of experience with nature under on going urbanization for urban ecosystem conservation.
