Appointed as the largest wetland on the planet, the Pantanal had 57.5% of its territory burned at least once in the last 36 years, which is equivalent to an area of 86,403 km² already affected by fire. Considering the action of the flames, 93% occurred in native vegetation and 7% in an anthropogenic area, the latter being linked to human intervention in the environment.
It was the Brazilian biome that burned the most in the period, according to a survey released this Wednesday (29) by MapBiomas, a coalition that brings together researchers from universities, NGOs and technology companies that monitor the occupation and use of land in Brazil.
The study points out that more than 2.3 million hectares were burned last year alone, for example. Using satellite images, the analysis of the Pantanal situation shows that areas of grassland vegetation and savannas were the most affected by the fire, corresponding to more than 75% of the burned parts.
The survey also brings other alarming data. The researchers identified, for example, that the area covered by water and flooded fields was reduced by 29% in the period between 1988 and 2018.
There were 5.9 million hectares at the beginning of the historical series, increasing to 4.1 million hectares in 2018, when the last flood was registered. The study points out that, last year, the area reduced to 1.5 million hectares, a data identified as the smallest in the last 36 years.
MapBiomas also registers that anthropic action jumped 261% between 1985 and 2020. The index results in an expansion of 1.8 million hectares in the period.
There was also a doubling of the pasture area in the Upper Paraguay Basin, which went from 15.9% to 30.9%. The activity is related to agribusiness. When considering the entire Pantanal, pasture represents today 16.1% of the territory.
There was also, in the same period of time, a jump in the occupation of agriculture, which went from 1.2% to 4.9%. Meanwhile, the savanna formation was reduced from 24.4% to 18%.
