Sob a Lupa do DETER: A Relação entre Degradação e Desmatamento na Amazônia

The report analyzes the spatial and temporal links between forest degradation and deforestation in the Brazilian Amazon from 2017 to 2020. Using INPE's DETER and PRODES systems, it finds that while direct local conversion of degraded areas into deforested land is low (10%), a significant portion of deforestation (30%) occurs within 1 km of previously degraded areas. The study highlights that degradation is more prevalent in medium and large private properties than deforestation is, suggesting that degradation can serve as a regional risk indicator for future deforestation and that policy efforts should be targeted based on land tenure categories.

• Between 2017 and 2020, the average annual forest degradation in the Amazon was approximately 17,000 square kilometers, which is nearly double the annual deforestation rate for the same period.
• Forest fires are the primary driver of degradation in the Amazon, with 'Cicatriz de Incêndio Florestal' (Forest Fire Scars) accounting for over 70% of the total degraded area, followed by 'Degradação' (16%) and 'Corte Seletivo' (12%).
• Degradation is geographically concentrated in the states of Mato Grosso (40% of the total) and Pará (33% of the total), a distribution that differs from clear-cut deforestation, where Pará accounts for 40% and Mato Grosso for 18%.
• The direct local conversion rate of degradation to deforestation is low; only 10% of the total area deforested between 2017 and 2020 was previously identified as degraded in the exact same location.
• There is a strong regional association between the two phenomena: over 20% of deforestation occurs within 0.5 km of previous degradation alerts, and this figure rises to 30% when the radius is expanded to 1 km.
• The distribution of forest loss varies by land tenure; medium and large private properties concentrate a higher proportion of degraded areas than they do deforested areas.
• Deforestation occurring near degraded areas is most concentrated in medium and large private properties, rural settlements, and undesignated areas.
