All states in the Brazilian Northeast Region registered an increase in deforestation in 2020

More than 10 thousand alerts of deforestation were detected, and a growth of 184% of deforested areas

The Atlantic Forest, the Caatinga, the Cerrado and the Amazon were heavily impacted by the increase in deforestation in all states in the Northeast Region of Brazil: Alagoas, Bahia, Ceará, Maranhão, Paraíba, Pernambuco, Piauí, Rio Grande do Norte and Sergipe . These biomes, as a whole, suffered a loss of 352,006 hectares of native vegetation in 2020 – an increase of 184% compared to the previous year. These numbers are in the Annual Report on Deforestation in Brazil - 2020, produced using data from MapBiomas Alerta, which were presented in a Webinar this Friday, July 16. 

The data point to 10,687 deforestation alerts detected in 2020 – which represents an increase of 243% compared to 2019. According to the coordinator of the Caatinga Team of MapBiomas Alerta, Washington Rocha, the substantial growth in 2020 occurred because of the Deforestation Alert System (SAD) Caatinga started to produce alerts, expanding the detection of deforested areas. “Agriculture, mainly on the western edge of the region, on the agricultural frontier of western Bahia and part of MATOPIBA (Maranhão, Piauí and Bahia), was the main responsible for the acceleration of deforestation”, comments Rocha. Among the States, Maranhão was the one that deforested the most in the Northeast: 167,366 hectares.

In the Northeast, 1,104 municipalities were registered with deforestation, out of a total of 1,793, that is, 61.57% of the municipalities had suppression of native vegetation in 2020. Balsas, in Maranhão, leads the ranking of municipalities with the most deforestation in the region, with 28,751 hectares devastated, 327% more than in 2019. Two cities in Bahia complete the podium: Formosa do Rio Preto, with 13,061 hectares (growth of 66%) and São Desidério (BA), with 11,976 hectares deforested - but it was the one that had the greatest growth, of 487%.

To increase monitoring and combat illegal deforestation, on May 31, MapBiomas signed a technical cooperation agreement with the Northeast Consortium. With the partnership, the project data will be used to produce knowledge about the territory and the region's biomes and foster preservation strategies.
