Descripción
The South-American Atlantic Forest region spans the nations of Argentina, Brazil and Paraguay. It is one of the most ecologically diverse in the world, yet one of the most vulnerable to deforestation with little research examining trends and drivers. Conservation interventions can play a critical role in protecting this forest, but the impact of their implementation remains unclear. We assessed the effects of forest protected area (FPA) designation on avoided deforestation across the Atlantic Forest region between 2000 and 2020 using the most recently available remote-sensed data in combination with geo-referenced socio-economic descriptors. Applying a pseudo-randomized approach, we quantified factors explaining establishment of FPAs and compared deforestation rates. Results show FPA designation lowered the odds of deforestation by about 14%, which is significantly higher than past assessments in other Latin American regions. Effectively, the estimated deforestation rate within FPA-designated areas (~5%) was nearly four-times lower than in non-FPA forests (19%). Future studies are needed to assess the impacts of FPAs on the socioeconomic wellbeing of forest-dependent communities across the Atlantic forest.
