Post-2020 biodiversity framework challenged by cropland expansion in protected areas

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.

Global Protected Areas as refuges for amphibians and reptiles under climate change

Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated distributional data for >14,000 (~70% of) species of amphibians and reptiles (herpetofauna) to perform a global assessment of the conservation effectiveness of PAs using species distribution models. Our analyses reveal that >91% of herpetofauna species are currently distributed in PAs, and that this proportion will remain unaltered under future climate change. Indeed, loss of species’ distributional ranges will be lower inside PAs than outside them.

A resilient and connected network of sites to sustain biodiversity under a changing climate

Motivated by declines in biodiversity exacerbated by climate change, we identified a network of conservation sites designed to provide resilient habitat for species, while supporting dynamic shifts in ranges and changes in ecosystem composition. Our 12-ystudy involved 289 scientists in 14 study regions across the conterminous United States(CONUS), and our intent was to support local-, regional-, and national-scale conservation decisions.

CKI OECM Workshop Report - January 2023

The CKI OECM Workshop Report consolidates the discussions, outcomes, recommendations and next steps following the Other Effective Area-based Conservation Measures Workshop, hosted by the National Environment Service, in partnership with Secretariat of Pacific Regional Environment Program and the UNEP World Conservation Monitoring Centre, on the 24th - 25th January 2023 in Rarotonga, Cook Islands.
