Abstract
Signatory countries to the Convention on Biological Diversity (CBD) are formulating indicators through 2030 under the post-2020 Global Biodiversity Framework (GBF). These goals include increasing the integrity of natural ecosystems. However, the definition of integrity and methods for measuring it remain unspecified. Moreover, nations did not achieve their 2011-2020 CBD targets, partly due to inability to monitor and report progress on these targets. Here, we define ecological integrity (EI) and suggest a framework to measure and evaluate trends in terrestrial EI. Our approach builds on three topics: the concept of ecological integrity, satellite-based Earth observation, and Essential Biodiversity Variables. Within this framework, EI is a measure of the structure, function and composition of an ecosystem relative to the pre-industrial range of variation of these characteristics. We recommend 13 indicators of EI to facilitate the efforts of nations to monitor, evaluate, and report during implementation of the post-2020 GBF. These indicators can help assess the condition of ecosystems relative to benchmark states, and track the degradation or improvement of ecosystem condition due to human impacts or restoration strategies. If operationalized, this framework can help Parties to the CBD systematically evaluate and report progress on achieving ecosystem commitments in the post-2020 GBF.
