Effects of forests and forest-related activities on the subjective well-being of residents in a Japanese watershed: An econometric analysis through the capability approach

Abstract

The purpose of this study is to assess the effects of natural capital on overall subjective well-being and forest-related subjective well-being. A questionnaire survey of 1698 urban and rural residents living in a watershed of Japan was conducted in February and March of 2016. Multiple regression and moderation effect analyses are conducted to statistically estimate the respective influences of natural capital, human-made capital, social capital, human capital, and other demographic factors on the above-mentioned two types of subjective well-being. Forest-related activities, human engagement with forests, are supposed to be of great societal and political importance for Japanese society, where past management practices have, at least quantitatively, restored forests from past deforestation. Our statistical analysis tests whether specific engagement with natural capital (forest-related activities) is positively related to subjective well-being. Following the capability approach developed by Amartya Sen, forest-related activities are interpreted as functionings, and the analysis highlights the importance of functionings as links between natural capital and subjective well-being. The results show several forest-related activities have statistically significant effects on overall and forest-related well-being. For respondents living in less forested areas and with less social capital, forest-related activities have stronger effects on their subjective well-being, suggesting that the individual subjective well-being of urban residents and those with less social capital can be enhanced through engagement with forests.
