As such, the positive carbon outcomes in PAs largely reflects proportionate reductions in the areal extent of deforestation (−38% lower in matched PAs), degradation (−25%), and increases in the area of vegetation growth (+12%) (Supplementary Fig. 3).
Contexto
What changed: Legal protection status across national parks, forest reserves, and wildlife areas established by 2014. Comparison: Matched unprotected woodland cells balanced on accessibility, extractable value, and agricultural suitability. Limits: Excluded 45% of protected woodlands lacking comparable counterfactuals; leakage to outside buffers could not be fully ruled out.
