The biosphere and ecosystems are complex adaptive systems, full of interacting feedback loops, which can sometimes exhibit tipping points where a small change in forcing causes an abrupt change in the state of the system that is hard to reverse. The risk of tipping points that are detrimental to biodiversity and the benefits we derive from it is escalating with global change. This risk includes both large-scale tipping points e.g. dieback of coral reefs or the Amazon rainforest, and smaller-scale tipping points e.g. abrupt land degradation, or loss of fish stocks. Equally for degraded ecosystems there are opportunities for positive tipping points of abrupt biodiversity gain. Businesses and finance are beginning to grapple with the financial materiality of biodiversity, but they are doing so in a linear thinking framework that has yet to incorporate the potential for tipping point changes.This PhD project will develop a framework to assess the materiality of biodiversity tipping points, e.g. in terms of the financial value of the industries dependent on the corresponding ecosystems. The aim will be to explore how the tipping point qualities of abruptness, self-propelling change and irreversibility alter the assessment of materiality (both of financial risks and opportunities). The student will undertake a series of case study applications of the framework ranging from inherently large-scale tipping points e.g. Amazon rainforest dieback, to local tipping points that may occur in many places e.g. abrupt land degradation, to opportunities for positive tipping points, e.g. tropical forest regeneration. The aim is twofold: to inform tools being used to assess associated financial risks and opportunities, and to explore the potential to enable positive action in the boardroom. For the latter, a series of evidence-based tipping points narratives will be developed, and their effectiveness tested. The PhD will be transdisciplinary - spanning relevant disciplines and involving action-oriented co-production of knowledge with J.O. Hambro capital management.

生物圈和生态系统是复杂的适应性系统，充满了相互作用的反馈回路，有时会出现临界点，即强迫的微小变化会导致系统状态发生难以逆转的突然变化。随着全球变化，对生物多样性以及我们从中获得的利益有害的临界点风险正在不断升级。这种风险包括大规模的临界点，例如珊瑚礁或亚马逊雨林的枯死，以及较小规模的临界点，例如土地突然退化或鱼类资源丧失。同样，对于退化的生态系统来说，生物多样性突然增加的积极转折点也有机会出现。企业和金融界正在开始应对生物多样性的财务重要性，但他们是在线性思维框架中这样做的，该框架尚未考虑临界点变化的潜力。该博士项目将开发一个框架来评估生物多样性临界点的重要性点，例如就依赖相应生态系统的产业的财务价值而言。目的是探索突然性、自我推动性变化和不可逆转性的临界点性质如何改变对重要性（金融风险和机遇）的评估。学生将对该框架进行一系列案例研究应用，范围从本质上大规模的临界点，例如亚马逊雨林枯死，到了许多地方可能发生的局部临界点，例如亚马逊雨林。土地突然退化，到积极临界点的机会，例如热带森林再生。其目的是双重的：为用于评估相关金融风险和机遇的工具提供信息，并探索在董事会中采取积极行动的潜力。对于后者，将开发一系列基于证据的引爆点叙述，并测试其有效性。该博士学位将是跨学科的——跨越相关学科，并涉及与 J.O. 以行动为导向的知识共同生产。汉布罗资本管理公司。
