Recently, natural capital has gained the attention of researchers and policymakers to promote sustainability. Previous studies have investigated the value of ecosystem services with respect to specific areas or species. Other studies have investigated the value of various types of ecosystem services and natural capital by integrating a number of findings using meta-analyses at the global level. Although these studies have provided information on either the global value of natural capital or the local value of specific subjects, there is little evidence on the country-specific values of natural capital in Japan, which will provide useful information for national environmental policies. We investigated the perceived values of terrestrial and marine natural capital in Japan using internet surveys and payment card methods. Data on various natural forms of capital were collected in a unified format and comparable manner. We found that some explanatory variables, such as perceived importance and visit frequency, as well as sociodemographic characteristics, are significant drivers of the willingness to pay (WTP), which maintains each aspect of natural capital. In addition, we conducted future predictions of terrestrial and marine natural capital using a scenario developed in a previous study. Our results indicate that Japan should follow a population-dispersed scenario for the sustainable management of natural capital up to 2050.

自然资本对人类的贡献:以日本为例

最近,自然资本已引起研究人员和决策者的关注,以促进可持续性。先前的研究已经调查了生态系统服务对于特定区域或物种的价值。其他研究则通过使用全球水平的荟萃分析来整合许多发现,从而研究了各种类型的生态系统服务和自然资本的价值。尽管这些研究提供了有关自然资本的全球价值或特定主题的地方价值的信息,但很少有证据表明日本对自然资本具有特定国家价值,这将为国家环境政策提供有用的信息。我们使用互联网调查和支付卡方法调查了日本陆地和海洋自然资本的感知价值。以统一的格式和可比的方式收集了各种自然资本形式的数据。我们发现,一些解释性变量,例如感知的重要性和访问频率以及社会人口统计学特征,是支付意愿(WTP)的重要驱动因素,而支付意愿维持了自然资本的各个方面。此外,我们使用先前研究中开发的方案对陆地和海洋自然资本进行了未来的预测。我们的结果表明,日本应遵循人口分散的方案,以实现到2050年的自然资本可持续管理。是支付意愿(WTP)的重要驱动力,支付意愿维持了自然资本的各个方面。此外,我们使用先前研究中开发的方案对陆地和海洋自然资本进行了未来的预测。我们的结果表明,日本应遵循人口分散的方案,以实现到2050年的自然资本可持续管理。是支付意愿(WTP)的重要驱动力,支付意愿维持了自然资本的各个方面。此外,我们使用先前研究中开发的方案对陆地和海洋自然资本进行了未来的预测。我们的结果表明,日本应遵循人口分散的方案,以实现到2050年的自然资本可持续管理。
