Degradação de nascentes em decorrência do avanço das atividades agropecuárias

Abstract

The study had as objective the use of remote sensing in the spatial and temporal evaluation of environmental degradation in springs of different river basins in the State of Mato Grosso. For assessment of the damage, was held the temporal dynamics of springs studied from 1985 to 2015. The springs and their water courses had their Degraded Permanent Preservation Area (DPPA) quantified and was also verified the time of occurrence of the environmental damage. With this information were performed calculations to estimate the values of functions losses and Environmental Services (PLES), caused by the uncontrolled advance of farming activities. All springs presented a high degree of degradation, both on DPPA and the damage duration, where the average time of occurrence was nearly 26 years, and consequently, the indemnification amounts related to environmental damage were high, considering that the lowest value was R$ 1,058,416.52 related to the losses of environmental functions and services not rendered to the environment. In the comparison between the basins, Paraguay’s can be considered the most degraded.
