In upland areas, where most of the springs that supply the Pantanal, only 40.7% of natural vegetation were maintained
Over 86% of the natural areas of the Pantanal lowlands are preserved. Despite the high level of preservation, environmental threats lurking on the Brazilian portion of the Upper Paraguay River Basin have not ceased. The alert is a group of non-governmental organizations operating in the region. According to the group, the concern is with the levels of conservation in the upper region. In upland areas, where most of the springs that supply the Pantanal, only 40.7% of natural vegetation were maintained.
The second edition of the study Monitoring of Vegetation Cover Change and Land Use in the Upper Paraguay River Basin (BAP), released today (20) in Campo Grande, Mato Grosso do Sul, which highlights the expansion of agricultural activities and works infrastructure in the region need to be monitored.
"While the lower part is still well preserved, the upper part of the Pantanal presents a great devastation. This relationship is important because everything that happens in the high plains will impact, "said Michael Becker, superintendent of conservation at WWF-Brazil.
The survey shows that in two years (between 2008 and 2010), 0.80% of the native vegetation in the lowland areas was occupied by human activities. On the plateau, the occupation occurred in 1.56% of the area. In the first evaluation of the area, the researchers showed that, between 2002 and 2008, the plateau has lost 4% of natural vegetation and native lowland areas were reduced by 2.4%.
"The data do not show large variations, but we're talking about an area that has been converted to upland pasture than 140 thousand hectares, ie 140 000 football fields. It is not the intention of this study attacking the productive sector, but we have to have special attention, "he said.
Becker also noted that works as dams in the region, which is characterized by constant flooding, siltation of rivers can mean and reduction in volume of fish. For the researcher, the data should be considered in the definition and implementation of local policies. The study highlights, for example, that environmental legislation should be enforced and adapted to the Pantanal.
"The Pantanal has specific characteristics of rangelands and obeys a rate of flooding which is one of the peculiar characteristics of the region. We have other rules than those applied to other rivers in the country, "Becker defended.
Monitoring of the Upper Paraguay River Basin has been conducted every two years by nongovernmental organizations. The analysis is performed only on the Brazilian side of the basin, which represents 60% of the border. With an area of almost 620,000 km square, the basin still occupies part of Bolivia and Paraguay.
The document was prepared by representatives of the International Conservation, Ecology and Action-ECOA, Avina Foundation and WWF-Brazil and Embrapa Pantanal.
