However, increasing evidence of continued biodiversity decline within PAs raises the question of whether fundamental {\textless}br{\textgreater}ecological and socio-economic constraints might actually affect PA effectiveness. Here we quantify how threats to biodiversity, {\textless}br{\textgreater}socio-economic context and conservation efforts play out across 114 PAs in 25 European and African countries. We found that {\textless}br{\textgreater}even in the presence of highly favourable socio-economic context and conservation efforts, it is not possible to completely {\textless}br{\textgreater}offset the intensity of threats and prevent biodiversity decline. Projections show that halting biodiversity decline across the {\textless}br{\textgreater}studied PA network may require at least a 35{\textpercent} increase in conservation efforts over a decade. However, as PAs approach {\textless}br{\textgreater}zero biodiversity loss, even greater efforts and resources would be needed because of the principle of diminishing marginal {\textless}br{\textgreater}returns. Our findings point to limited effectiveness of PAs and their management that might not be possible to address by sim-{\textless}br{\textgreater}ply increasing resources. Additionally, the adoption of core design principles of sustainable systems that take into account the {\textless}br{\textgreater}social{\textendash}ecological contexts of PAs could help overcome the observed hurdles of limited effectiveness and thus better integrate {\textless}br{\textgreater}PAs into sustainable development efforts.}}, journal = {{Nature Sustainability}}, volume = {5}, pages = {861--868}, }
