Combate ao Desmatamento Ilegal

The document argues that strengthening 'comando e controle' (command and control) is essential for protecting Brazil's native vegetation, which is critical for environmental conservation, international reputation, and the competitiveness of the agribusiness sector. It highlights the success of the DETER system in the Amazon, which helped reduce annual forest loss by over 80% and avoided the loss of more than 2 million hectares per year during its first five years. However, it identifies gaps such as the inability to detect small-scale deforestation (under 25 hectares) and the lack of monitoring for secondary vegetation. The authors recommend developing technology for small-scale detection and forest degradation, monitoring forest regeneration, expanding remote sensing to all national biomes, and implementing land tenure regularization in public lands and agrarian reform settlements.

• The implementation of the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (PPCDAm) contributed to a reduction of more than 80% in the annual rate of forest loss.
• The DETER system, developed by Inpe, uses high-frequency satellite imagery to provide near real-time monitoring of the Brazilian Legal Amazon, allowing Ibama to focus enforcement actions via georeferenced alerts.
• Environmental enforcement through the DETER system is estimated to have prevented the loss of over 2 million hectares of Amazon forest annually during its first five years of operation, without negatively impacting agricultural production.
• A significant technical limitation of the original DETER system is its inability to detect forest loss in areas smaller than 25 hectares, which may have led offenders to strategically shift toward small-scale deforestation to avoid detection.
• The DETER-B system was developed to address these gaps, capable of detecting forest loss in areas above 1 hectare and distinguishing between degradation, fire scars, and selective logging, though it has lower temporal frequency than the original system.
• Secondary vegetation is currently vulnerable because satellite monitoring systems are designed for primary vegetation; in the Amazon, there were over 17 million hectares of secondary vegetation in 2014.
• Since 2010, approximately two-thirds of deforested areas in the Amazon occurred on public lands, specifically in agrarian reform settlements (30%) and non-designated areas (25%).
• Remote sensing monitoring has been expanded from the Legal Amazon to include the Cerrado, covering 73% of the national territory in near real-time.
