ABSTRACT

This paper characterizes the value of biodiversity and ecosystem resilience by formalizing a stochastic dynamic bioeconomic model of pollinator diversity under climate changes, with an application to oil rapeseed production in the Stockholm region of Sweden. It studies the optimal provision of semi-natural habitat for two different pollinator bee species: bumble bees and solitary wild bees. It is found that, despite being less effective, solitary bees hold considerable resilience value due to the differences in how the two species respond to temperature shocks. The paper also discusses the role of spatial aspects, in particular the reduced pollination effectiveness due to spatially uneven allocation of semi-natural habitats. It is found that spatial unevenness leads to an increase in the habitat provision, with an attendant reduction in the resilience value of solitary bees.

重视生物多样性和复原力:斯德哥尔摩地区传粉媒介多样性的应用

摘要

本文通过对气候变化下传粉媒介多样性的随机动态生物经济模型进行形式化来表征生物多样性和生态系统复原力的价值,并将其应用于瑞典斯德哥尔摩地区的油菜籽生产。它研究了两种不同的传粉蜂物种:大黄蜂和单生野生蜂的半自然生境的最佳提供。已发现,尽管效率较低,但由于两种物种对温度冲击的反应方式不同,它们仍具有相当大的复原力值。本文还讨论了空间方面的作用,尤其是由于半自然生境在空间上分配不均而导致的授粉效率降低。发现空间不均匀会导致栖息地供应增加,
