摘要

世界各地的许多自然资源正被过度开发(粮农组织渔业部,2022;IPBES,2019),有时甚至到了生态系统崩溃的边缘。对于海洋系统来说尤其如此,过度捕捞是一个持续的、全球范围内日益严重的生态和经济问题,也会对社会和文化产生影响。海洋生态系统面临着跨越临界点的威胁,导致捕捞量、生物量以及渔获量的突然变化(Möllmann等人,2021)。在过去的几年里,临界点分析已经扩展到各种跨学科领域,如自然资源建模。浅水湖理论中有一个历史性的例子,其中已经证明存在几种稳定状态,要想从健康的生态系统逆转为富营养化状态,可能需要的不仅仅是去除营养物质(Scheffer,1997)。这些系统的最佳管理需要跨学科的方法,既要考虑生态系统易受倾倒的影响,又要考虑多种经济成本和效益(Voss&Quaas,2021)。从自然资源系统的综合角度来看,考虑到生态和社会经济过程之间的反馈,系统中的临界点并不一定是坏事。这些系统可能走在一条不可持续的道路上,实现可持续性可能需要将系统转向另一个吸引领域(Derissen&Quaas,2013)。2021年世界自然资源建模会议的目的是讨论如何改变生态经济系统的动态,以实现长期可持续性。随着全球疫情限制的实施,这是资源建模协会的第一次完全虚拟的会议。由于成本低,会议方便所有时区,会议成为一个特别具有包容性的活动,有来自世界各地的广泛论文和主题。本期特刊的论文集精选了对临界点分析和耦合生态社会经济系统管理领域的贡献。在“给小费还是不给小费:社会生态系统的引爆点分析窗口”中,Riekhof等人(2022)介绍了一个新的框架,以增加对社会生态系统过程和引爆点的理解,并讨论替代稳定状态的可取性。在“具有替代稳定状态的随机生态系统的程式化模型”中,Stecher和Baumgärtner(2022)通过在生态系统状态中引入随机性并确定了许多重要应用,推进了多稳定性领域。最后,在“海洋哺乳动物和鱼类的联合管理:北欧-波罗的海国家的鳕鱼和灰海豹案例”中,Blomquist等人(2022)指出,在有管理的海洋生态系统中,考虑捕食者和捕获猎物的多重成本和收益的重要性。我们要感谢作者和审稿人以及主编Shandelle Henson的贡献和支持。

Editorial
Many natural resources around the world are being overexploited (FAO Fisheries Department, 2022; IPBES, 2019), sometimes to the extent that ecosystems are on the brink of collapse. This is especially true for marine systems where overfishing is a continuous and globally increasing ecological and economic issue, also resulting in impacts on society and culture. Marine ecosystems are threatened to cross tipping points, leading to abrupt changes in recruitment, biomass, and consequently in catches (Möllmann et al., 2021). In the past years, tipping point analysis has spread to various interdisciplinary fields such as natural resource modeling. A historic example is found in the shallow lakes theory where several stable states have been shown to exist and to reverse tipping from a healthy ecosystem to a eutrophicated state may require more than just nutrient removal (Scheffer, 1997). The optimal management of these systems requires interdisciplinary approaches that account for the vulnerability of ecosystems to tipping but also to consider multiple economic costs and benefits (Voss & Quaas, 2021). In an integrated perspective of natural resource systems that takes the feedbacks between ecological and socioeconomic processes into account, tipping points in the system are not necessarily a bad thing. These systems may be on an unsustainable path, and achieving sustainability may require to shift the system toward another domain of attraction (Derissen & Quaas, 2013). The aim of the 2021 World Conference on Natural Resource Modeling was to discuss how to change ecological‐economic system dynamics toward long‐term sustainability. As worldwide pandemic restrictions were in place it was the first fully virtual conference of the Resource Modeling Association. Owing to low costs and sessions convenient to all time zones the conference became a particularly inclusive event, with a wide range of papers and topics from all over the world. The collection of papers in this special issue represents a selection of contributions toward the fields of tipping point analysis and the management of coupled ecological socioeconomic systems. In “To tip or not to tip: The Window of Tipping Point Analysis for social‐ecological systems” Riekhof et al. (2022) introduce a new framework to increase the understanding of processes and tipping points in social‐ecological systems and discuss the desirability of alternative stable states. In “A stylized model of stochastic ecosystems with alternative stable states” Stecher and Baumgärtner (2022) advance the field of multistability by introducing stochasticity in the ecosystem state and identifying a multitude of important applications. Finally, in “Joint management of marine mammals and a fish species: The case of cod and grey seals in the Nordic‐Baltic Sea countries” Blomquist et al. (2022) point out the importance of taking multiple costs and benefits of predators and harvested prey in a managed marine ecosystem into account. We would like to thank the authors and reviewers as well as the editor in chief Shandelle Henson for their contributions and support.

期刊介绍: Natural Resource Modeling is an international journal devoted to mathematical modeling of natural resource systems. It reflects the conceptual and methodological core that is common to model building throughout disciplines including such fields as forestry, fisheries, economics and ecology. This core draws upon the analytical and methodological apparatus of mathematics, statistics, and scientific computing.
