O Brasil sabe como deter o desmatamento na Amazônia
Summary
This policy brief argues that Brazil's satellite-based monitoring (DETER) and law enforcement (IBAMA) system is a highly cost-effective tool that prevented an average of 27,000 km² of deforestation per year between 2007 and 2016. The document demonstrates that these measures do not hinder agricultural production and avoid nearly 1 billion tCO2 emissions annually. It warns that a proposed 50% budget cut for 2020 could increase deforestation by 45% and recommends strengthening federal financial and institutional support for these systems.
Key insights
- Brazil implemented a highly effective monitoring and law enforcement system starting in 2004, which contributed to reducing the Amazon deforestation rate by more than 80% over a decade.
- A study by CPI/NAPC PUC-Rio estimates that monitoring and law enforcement efforts prevented the loss of an average of 27,000 km² of Amazon forest per year between 2007 and 2016. Without these strategies, the total forest loss during this period would have been more than four times higher than what was actually observed.
- The Real-Time Deforestation Detection System (DETER), developed by the National Institute for Space Research (INPE), revolutionized law enforcement by using satellite imagery to provide near real-time alerts on forest loss. This allows the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA) to target operations and catch offenders in the act, which is critical for applying costly sanctions such as the seizure and destruction of equipment.
- Evidence suggests that environmental law enforcement does not harm local agricultural production; instead, areas with a higher presence of inspection in one year typically showed improved agricultural production in the following year. Furthermore, the reduction of deforestation in specific areas did not lead to the displacement of illegal activities to neighboring regions.
- The monitoring and law enforcement strategy is highly cost-effective. Avoiding 27,000 km² of forest loss annually prevents nearly 1 billion tCO2 emissions per year. With an estimated annual cost of US$685 million (the combined budgets of INPE and IBAMA), the break-even carbon price is US$0.69/tCO2, which is significantly lower than current global carbon prices, many of which exceed US$10/tCO2e.
- Proposed budget cuts to environmental monitoring and law enforcement pose a significant risk. A 50% reduction in the budget for these activities, as originally proposed for 2020, could lead to a 45% increase in deforestation in the Amazon.
