Have you ever looked at my background picture (banner) on LinkedIn? It shows a deeply needed quantification of the "bending the curve of biodiversity loss" trajectory. My experience using iterations of this chart with businesses since 2019 is that it really helps everyone understand what is at stake and companies' potential role. 📈 Quantifying the trajectory Most of the representation of the Nature Positive concept shows a similar curve but without any figures on the vertical axis. Here, we quantify how much ecosystem condition is remaining, how much we are losing each year, and pathways towards 2050. 📏 The metric Here we use the #MeanSpeciesAbundance (MSA) metric to quantify a trajectory. MSA represents the health of an ecosystem (100 % is a healthy ecosystem) and is an ecosystem condition metric. It is defined as the average of the abundances of native species. The use of the Mean Species Abundance (MSA) here does not imply any endorsement for this metric and does not mean it is *the* metric to use to build a global budget. But one metric had to be chosen to illustrate the concept. 🌏 Link to Planetary Boundaries The other element I really love about this chart is that it shows one of the biodiversity Planetary Boundary. It illustrates clearly that we are already in the zone of uncertainty (actually the danger zone, but science does not yet quantify exactly its threshold in MSA) and what needs to be done to come back within the safe operating space. 🔦 Sources and further explanations Our “Bending the curve” trajectory is an unofficial translation of Goal A of the Convention of Biological Diversity’s Global Biodiversity Framework. It integrates the biodiversity planetary boundary estimated by Lucas and Wilting (2018) and is inspired by work from CDC Biodiversité. Two scenarios are represented: the Shared Socio-economic Pathways 2 scenario (SSP2, in black), also called the “Middle of the road” scenario, meaning the world follows a path in which social, economic, and technological trends do not shift markedly from historical patterns, and the Goal A scenario (in green), that follows and implements the CBD’s GBF’s goal.

And we are organizing a webinar with Simas Gradeckas on 12 December at 17:00 CET to present our indicators & metrics of biodiversity credit work: https://lnkd.in/eyPHtbTD
