Are investments to promote biodiversity conservation and ecosystem services aligned?
研究了美国明尼苏达州保护资金在生物多样性保护和生态系统服务目标之间的一致性，发现两者高度一致，且保护投资的收益远超成本。
The conservation community is divided over the proper objective for conservation, with one faction focused on ecosystem services that contribute to human well-being and another faction focused on the intrinsic value of biodiversity. Despite the underlying difference in philosophy, it is not clear that this divide matters in a practical sense of guiding what a conservation organization should do in terms of investing in conservation. In this paper we address the degree of alignment between ecosystem services and biodiversity conservation strategies, using data from the state of Minnesota, USA. Minnesota voters recently passed an initiative that provides approximately $171m annually in dedicated funding for conservation. We find a high degree of alignment between investing conservation funds to target the value of ecosystem services and investing them to target biodiversity conservation. Targeting one of these two objectives generates 47–70 per cent of the maximum score of the other objective. We also find that benefits of conservation far exceed the costs, with a return on investment of between 2 to 1 and 3 to 1 in our base-case analysis. In general, investing in conservation to increase the value of ecosystem services is also beneficial for biodiversity conservation, and vice-versa. Copyright 2012, Oxford University Press.
