生物多样性为规避风险的经济行为者提供了保障，以防止生态系统服务的不确定性。我提出了一个概念性的生态经济模型，结合（一）目前的结果，从生态学之间的关系，生物多样性，生态系统功能和生态系统服务的提供与（二）经济方法来研究决策的不确定性。在此框架下，我（1）确定生物多样性的保险价值，（2）研究投资生物多样性保护和购买金融保险之间的最优资金配置，（3）分析金融保险市场的不同制度对生物多样性保护的影响。我的结论是，生物多样性作为一种自然保险的形式，规避风险的生态系统管理者对过度或不足提供生态系统服务。因此，生物多样性具有保险价值，这是除了通常的价值论点之外的一个价值组成部分，例如直接或间接的使用或非使用价值。在这方面，生物多样性和金融保险是替代品。因此，金融保险的可用性和准确的制度设计影响着生物多样性保护的水平。
Biodiversity provides insurance against the uncertain provision of ecosystem services which are being used by risk-averse economic agents. I present a conceptual ecological-economic model that combines (i) current results from ecology about the relationships between biodiversity, ecosystem functioning, and the provision of ecosystem services with (ii) economic methods to study decision-making under uncertainty. In this framework I (1) determine the insurance value of biodiversity, (2) study the optimal allocation of funds in the trade-off between investing into biodiversity protection and the purchase of financial insurance, and (3) analyze the effect of different institutional regimes in the market for financial insurance on biodiversity protection. I conclude that biodiversity acts as a form of natural insurance for risk-averse ecosystem managers against the over- or under-provision with ecosystem services. Therefore, biodiversity has an insurance value, which is a value component in addition to the usual value arguments, such as direct or indirect use or non-use values. In this respect, biodiversity and financial insurance are substitutes. Hence, the availability, and exact institutional design; of financial insurance influence the level of biodiversity protection.
