Brazil's Annual Deforestation Report - 2019

The deforested area in Brazil in 2019 is equivalent to 8 times the municipality of São Paulo

The first Annual Report on Deforestation in Brazil, released this Tuesday (26/05), shows, in an unprecedented way, the loss of native vegetation detected in all biomes of the country in 2019. For the first time, warnings of deforestation in the territory were analyzed and consolidated in a single survey, pointing out that Brazil has lost at least 1,218,708 hectares (12,187 km²) of native vegetation, an area equivalent to eight times the municipality of São Paulo.

More than 60% of the deforested area is in the Amazon, with 770 thousand hectares devastated. The second biome in which there was more loss was the Cerrado, 408.6 thousand hectares. Far behind are Pantanal (16,500 ha), Caatinga (12,100 ha), Atlantic Forest (10,600 ha) and Pampa (642 ha).

Amazonia and Cerrado are the best monitored biomes, with continuous monitoring systems, adapted for the respective regions. As the other biomes use data from a global system, without adaptations for specific conditions (types of vegetation, climate and landscape seasonality, for example), the calculated values ​​are considered conservative, that is, they may be undersized.

MapBiomas Alerta is a system for validating and refining alerts on deforestation, degradation and regeneration of native vegetation, with high resolution images, launched in June 2019. The analysis starts from the alerts generated by the Deter (Inpe), SAD systems (Imazon) and Glad (University of Maryland). The data is validated and refined with the support of high resolution satellite images (three meters), which allow to identify with great precision the deforested areas.

“Based on this methodology, the first Annual Report on Deforestation in Brazil was developed, which details the time and space where it is being deforested in the country. The analysis of each alert generates a report, which can be used by all agencies - public and private ”, says the coordinator of MapBiomas, Tasso Azevedo. The reports of the alerts are available on the internet at:

The methodology developed by MapBiomas Alerta allows to measure the speed of deforestation in an unprecedented dimension. Thus, it was possible to point out that the area deforested more quickly in 2019 is in the municipality of Jaborandi (BA), with 1,148 hectares, between May 8 and 27, reaching an average of 60 hectares per day. In terms of the size of deforestation, the largest area detected is in Altamira (PA): in a single event, 4,551 hectares of Amazon forest were cut down.

The states with the most events were: Pará (18.5 thousand), Acre (9.3 thousand), Amazonas (7 thousand), Rondônia (5.3 thousand) and Mato Grosso (4.7 thousand). In a deforested area, the top of the list is occupied by: Pará (299 thousand ha), Mato Grosso (202 thousand ha) and Amazonas (126 thousand ha).

When the ranking by municipalities is organized, half of the entire deforested area is at 50. Among the ten that most deforested in 2019, four are from Pará, three from Amazonas, one from Bahia, one from Mato Grosso and one from Rondônia. In total, 1,734 municipalities had areas of deforestation detected in 2019.

Another fundamental aspect: intersections with territorial layers, such as Conservation Units, Indigenous Lands and rural properties, carried out based on the Rural Environmental Registry (CAR), data on vegetation suppression authorizations and a forest management plan.

More than three quarters of the alerts overlap with at least one property registered in the CAR. There were 42.6 thousand rural properties with registered alerts, which represents 0.7% of the more than 5.6 million properties registered in the CAR. Just over a third of the alerts (38%) overlap totally or partially over legal reserve areas, areas of permanent or spring preservation and less than 1% have registered the authorization to suppress vegetation. "The report indicates that the rate of illegality in deforestation is extremely high, to the point that legal deforestation represents more the exception than the rule", concludes Azevedo.

About MapBiomas: a multi-institutional initiative, involving universities, NGOs and technology companies, focused on monitoring changes in land cover and use in Brazil.
