The Living Planet Index (LPI) is a leading global biodiversity indicator based on vertebrate population time series. Since it was first developed over 25 years ago, the LPI has been widely used to indicate trends in biodiversity globally, primarily reported every two years in the Living Planet Report. Based on relative abundance, a sensitive metric of biodiversity change, the LPI has also been applied as a tool for informing policy and used in assessments for several multilateral conventions and agreements, including the Convention on Biological Diversity 2010 Biodiversity Target and Aichi targets. Here, we outline all current and some potential uses of the LPI as a policy tool and explore the use of the LPI in policy documents to assess the reach of the LPI geographically and over time. We present limitations to the use of this indicator in policy, primarily relating to the development of the index at the national level, and suggest clear pathways to broaden the utility of the LPI and the underlying database for temporal and spatial predictions of biodiversity change. We also provide evidence that the LPI can detect recoveries in biodiversity and suggest its suitability for measuring progress towards the goal of biodiversity recovery by 2050.This article is part of the discussion meeting issue 'Bending the curve towards nature recovery: building on Georgina Mace's legacy for a biodiverse future'.
生物多样性指数（LPI）是一项基于脊椎动物种群时间序列的全球领先生物多样性指标。自25年前首次制定以来，LPI已被广泛用于指示全球生物多样性趋势，主要每两年在《生物多样性报告》中公布。基于相对丰度这一生物多样性变化的敏感指标，LPI还被用作政策参考工具，并用于多项多边公约和协定的评估，包括《生物多样性公约》2010年生物多样性目标和爱知目标。在此，我们概述了LPI作为政策工具的所有当前及一些潜在用途，并探讨LPI在政策文件中的使用情况，以评估LPI在地理和时间上的覆盖范围。我们提出了该指标在政策使用中的局限性，主要涉及国家层面指数的编制，并提出了明确的途径，以扩大LPI及其基础数据库在生物多样性变化时空预测方面的效用。我们还提供了证据，证明LPI能够检测生物多样性的恢复情况，并表明其适用于衡量到2050年生物多样性恢复目标的进展。本文是“扭转曲线走向自然恢复：基于乔治娜·梅斯的遗产实现生物多样的未来”讨论会议题的一部分。
