Abstract

Protected areas (PAs) are primary biodiversity conservation instruments under the Convention on Biological Diversity (CBD). Despite a substantial body of research assessing their causal impact, a comprehensive global synthesis remains lacking. This study examines trends in PA effectiveness on biodiversity loss using impact evaluation studies published between 2000 and 2023. From 129 identified studies, matching emerged as the predominant method, with deforestation and forest cover as the most frequently assessed outcomes. Notably, none of the reviewed studies incorporated CBD-approved biodiversity indicators, such as the Red List Index, and only one applied the Biodiversity Intactness Index (BII) established by the Kunming-Montreal Global Biodiversity Framework. These findings underscore the need for future research to integrate standardized biodiversity metrics as outcome variables. Methodological advancements in impact evaluation are equally essential to strengthen conservation policy assessments and support evidence-based decision-making within international biodiversity agreements.

利用影响评价方法研究陆地保护区减少生物多样性丧失有效性的总体趋势。

保护区（pa）是《生物多样性公约》（CBD）下的主要生物多样性保护手段。尽管有大量研究评估了它们的因果影响，但仍然缺乏全面的全球综合研究。本研究利用2000年至2023年间发表的影响评价研究，探讨了PA在生物多样性丧失方面的有效性趋势。在129项已确定的研究中，匹配成为主要方法，森林砍伐和森林覆盖是最常评估的结果。值得注意的是，被审查的研究中没有一项采用cbd认可的生物多样性指标，如红色名录指数，只有一项采用了昆明-蒙特利尔全球生物多样性框架建立的生物多样性完整性指数（BII）。这些发现强调了未来研究将标准化生物多样性指标作为结果变量的必要性。在影响评价方面取得方法上的进步对于加强保护政策评估和支持国际生物多样性协定中的循证决策同样至关重要。
