The Kunming-Montreal Global Biodiversity Framework (GBF) marks one of the most ambitious environmental agreements of the 21st century. Yet despite the ambition, and the considerable change in approach since negotiating its predecessor (the 2025 Vision and Aichi targets), the many pressures, including working through a global pandemic mean that the final agreement, despite several years of delay, is weaker than might have been hoped for.

The Kunming-Montreal Global Biodiversity Framework envisages an increasing reliance on large-scale private finance to fund biodiversity targets. We warn that this may pose contradictions in delivering conservation outcomes and propose a critical ongoing role for direct public funding of conservation and public oversight of private nature-related financial mechanisms.

Protected areas (PAs) are essential for biodiversity conservation but are threatened by cropland expansion. Recent studies have only reported global cropland expansion in large PAs between 1990 and 2005. However, the amount of cropland expansion in global PAs (including relatively small PAs) since the 2000s is unclear. Using 30-m cropland maps, we find that the cropland expansion in PAs accelerated dramatically from 2000 to 2019, compared with that of global croplands.

The Kunming-Montreal Global Biodiversity Framework (GBF)1 was adopted during the 15th Conference of Parties (COP15) of the UN Convention on Biological Diversity (CBD) at 3:30 a.m. on the morning of December 19, 2022, against a backdrop of protests by African countries. This mirrored the fractious context of conservation over the last century and recent decades, and the 3.5 years of negotiation of the GBF leading up to COP15.
