Lançamos a Coleção 5 (1985-2019)



Accumulated reduction is 87.2 million hectares, shows Collection 5 by MapBiomas. Updated maps and data on land use and land cover will be released this Friday (28).

Friday, August 28, 2020

Updated maps and data from MapBiomas show that Brazil lost 87.2 million hectares of areas of native vegetation, from 1985 to 2019. This is equivalent to 10.25% of the national territory. The pace of loss of native vegetation accelerated in Brazil between 2018 and 2019. This is what is shown in Collection 5 of MapBiomas.

The historical series of maps and annual data on land cover and use in the country, from 1985 to 2019, was presented this Friday (28th), at the 5th Annual MapBiomas Seminar: Revealing Land Use in Brazil with Science and Transparency . The event was broadcast on YouTube and Facebook.

The update of the platform, for public use and free of charge, brings new features and layers of information, such as the evolution of the irrigation area, the evaluation of the quality of pastures and the mapping of natural vegetation in regeneration throughout the national territory.

Data from MapBiomas Collection 5 show that more than half of the loss of native vegetation in Brazil (44 Mha) occurred in the Amazon. In the Cerrado, the reduction was 28.5 Mha. Among the six Brazilian biomes, it was the one that most lost native vegetation in proportional terms: 21.3%

Pampa also had a high rate of decrease in remaining vegetation cover: 20% (2.3 Mha). On the other hand, the area of ​​planted forests in the Rio Grande do Sul biome grew 4.9 times.

In the Pantanal, the loss of native vegetation was 12%, with a 4.7-fold increase in the total area of ​​planted pastures. In the Caatinga, the fall in the area of ​​remaining vegetation was 11%, with an expansion of 26% for agriculture and livestock.

In the Atlantic Forest, 57% of the country's urban areas are found. The area of ​​urban infrastructure in the biome grew 2.5 times from 1985 to 2019; the area of ​​agriculture has doubled.

Of all the loss of natural vegetation in Brazil, including forest, savannah, fields and mangroves, at least 90% was occupied by agricultural use, whose expansion was 78 million hectares (43% growth since 1985)

MapBiomas Collection 5: more data, more depth, more transparency

Among the novelties of Collection 5 are deforestation and regeneration data, such as the rate of loss of native vegetation by biome and views of the territories where, proportionally, there is more secondary vegetation.

Although the country has 66.8% of the territory covered by native vegetation, this does not mean that they are preserved areas. "The MapBiomas survey points out that at least 9.3% of all natural vegetation in Brazil is secondary, that is, they are areas that have already been deforested and converted to human use at least once", explains Tasso Azevedo, general coordinator MapBiomas. "Of the area that has never been deforested, there is a fraction that has already been degraded by fire or predatory logging. Quantifying this process of forest degradation is one of the next challenges that we will face", he adds.

Monitoring of agricultural areas included data on irrigation, temporary crops such as soy and cane, and perennials, as well as improvements in the mapping of pastures and agriculture in Brazil.

Among the works in experimental and unprecedented version, is the evaluation of the quality of pastures in Brazil for the years 2010 and 2018. “The data show that there was an important evolution. The area of ​​pasture with signs of degradation fell from 72% to just over 60% in 8 years ”, says the professor at UFG and coordinator of the MapBiomas pasture team, Laerte Ferreira. Understanding the degree of degradation of pastures is essential both to control greenhouse gas emissions and to improve productivity and reduce the pressure on deforestation in biomes. “Degraded pastures emit carbon, while well managed ones capture carbon in the soil”, he explains.

MapBiomas' annual coverage and land use maps of Brazil have a resolution of 30 meters (each pixel represents an area of ​​30 meters x 30 meters). The collection can be downloaded and used in geographic information systems or accessed through the web platform available at It is possible to view the data in territorial sections of biomes, states, municipalities, indigenous lands, conservation units, transport infrastructure, energy, mining and hydrographic basins; maps and statistics modules for deforestation / suppression and recovery of forests and native vegetation in all biomes in the country; as well as infographics and a mural map of Brazil and each biome. The tool is public and free.

Webinars will deepen Collection 5 data by biome and cross-cutting themes

In September and October, MapBiomas will promote two webinars a week to present the novelties of Collection 5 by biome and cross-cutting themes, discussing the data collected with experts and users of the platform.

"The webinars will allow a more in-depth debate on the situation and the evolution of activities in each biome, qualifying the debate on the sustainable use of Brazilian territory", says Júlia Shimbo, a researcher at IPAM and a scientific coordinator at MapBiomas.

The online events will take place on Tuesdays and Fridays, between September 4 and October 9, always from 10:30 am to 12:00 pm, with transmission on YouTube.

About MapBiomas: multi-institutional initiative, involving universities, NGOs and technology companies, focused on monitoring changes in land cover and use in Brazil. This platform is today the most complete, updated and detailed spatial database of land use in a country available in the world. Other MapBiomas initiatives are under development in Indonesia, across the Pan-Amazon, in addition to Argentina, Paraguay, Bolivia and Uruguay. All MapBiomas data, maps, methods and codes are made available publicly and free of charge on the initiative's website:
