O BRASIL PRECISA MONITORAR SUA REGENERAÇÃO TROPICAL
Summary
The report highlights that while Brazil has successfully monitored primary forest loss, secondary vegetation (regeneration) remains 'invisible' to official systems like PRODES and DETER. It argues that monitoring this vegetation is technologically feasible and essential for meeting international reforestation goals and enforcing the Forest Code. The authors propose a dual-system approach—one for long-term measurement and one for short-term alerts—utilizing existing satellite imagery and an estimated annual budget of US$500,000.
Key insights
- Secondary vegetation in the Brazilian Amazon is significant and growing, but it is not tracked by official monitoring systems. In 2014, over 17 million hectares showed signs of tropical regeneration, representing nearly 25% of all historically deforested areas in the Amazon; between 2004 and 2014, this area increased by more than 70%.
- Current official monitoring systems, PRODES and DETER, are designed to detect the loss of primary vegetation and ignore areas already marked as deforested, creating a 'blind spot' for regeneration.
- The lack of official data on secondary vegetation prevents Brazil from verifying international reforestation targets and ensuring rural landowners comply with restoration requirements in the Forest Code.
- Implementing a remote monitoring system for tropical regeneration is technologically feasible and could be achieved in less than one year with an estimated annual investment of US$500,000.
- The authors recommend a dual-system approach: a high-resolution system for medium-to-long-term measurement of gains and losses, and a high-frequency alert system to detect short-term suppression of secondary vegetation for law enforcement purposes.
- The proposed monitoring systems can be built using existing satellite imagery from LANDSAT/OLI and CBERS/WFI, though cloud cover in the Amazon requires adaptations such as aggregating data into quarterly periods.
