Global biodiversity is in decline (IPBES, 2020). Understanding how wildlife populations respond to anthropogenically induced climate-change, land-use change and other threats is critical to 'bend-the-curve' of biodiversity loss (Mace et al, 2020). The Living Planet Index is a global dataset of 28,000 population trends of over 4400 vertebrate species that offers a unique tool for biodiversity assessment. It has been used nationally and internationally to assess progress towards biodiversity goals such as the Aichi targets, IPBES and post-2020 framework, and informs the Living Planet Report, WWF's biennial flagship report with an estimated reach of >100 million people. This project offers a unique opportunity to improve an impactful and widely-used global biodiversity indicator. It will develop a 'Living Planet Index 2.0', a next-generation indicator of trends in global wildlife abundance that uses state-of-the-art statistical modelling. The project includes four goals:1) Quantify and minimize biases caused by data gaps in the Living Planet Index database to best inform policy in locations with sparse data coverage.2) Characterize key regional and global drivers of biodiversity change by jointly modelling threat data (including climate and land use changes) and wildlife population trends.3) Identify extreme population changes (very rapid increases or declines) characterized as plausible vs unrealistic (eg, changes too rapid for the species' life history), and develop methods to reduce sensitivity of aggregated index assessments to such extremes.4) Build an easy-to-use and accessible dashboard for Living Planet Index 2.0 that combines improvements from goals 1-3 and directly informs policy-makers and prioritises conservation actions.

全球生物多样性正在下降（IPBES, 2020）。了解野生动物种群如何应对人为引起的气候变化、土地利用变化和其他威胁，对于“扭转”生物多样性丧失的趋势至关重要（Mace et al ., 2020）。地球生命力指数是一个包含超过4400种脊椎动物的28000个种群趋势的全球数据集，为生物多样性评估提供了一个独特的工具。它已在国内和国际上被用于评估生物多样性目标的进展情况，如爱知目标、IPBES和2020年后框架，并为世界自然基金会两年一次的旗舰报告《地球生命力报告》提供信息，该报告估计覆盖10亿人。该项目为改进具有影响力和广泛使用的全球生物多样性指标提供了独特的机会。它将开发“地球生命力指数2.0”，这是使用最先进的统计模型的下一代全球野生动物数量趋势指标。该项目包括四个目标：1)量化并尽量减少地球生命力指数数据库中数据缺口造成的偏差，以便在数据覆盖较少的地区为政策提供最佳信息。2)通过联合模拟威胁数据（包括气候和土地利用变化）和野生动物种群趋势，表征生物多样性变化的关键区域和全球驱动因素。3)识别具有似是而非特征的极端种群变化（非常迅速的增加或减少）（例如，物种生活史的变化太快），并制定方法来降低综合指数评估对这种极端的敏感性。4)为“地球生命指数2.0”建立一个易于使用和访问的仪表板，结合目标1-3的改进，直接通知政策制定者并优先考虑保护行动。
