This research deals with an environmental analysis of Veredas, located in Correntinho stream,
which is located in the city of Miracema do Tocantins about 70 km from Palmas, capital of the
state of Tocantins. The present research aimed to analyze the environmental conditions of
Veredas of Correntinho stream, located in the city of Miracema do Tocantins (TO). Its main
goal is to verify the environmental conditions of Veredas, located in the main course of the
stream in question. The methodology adopted was the application of the Normalized Difference
Vegetation Index (NDVI), the Normalized Difference Water Index (NDWI), a Rapid Vereda
Assessment Protocol (PARV), an analysis of land use and occupation, and at the end, correlate
the obtained results. As a result, it was obtained the characterization of the geoenvironmental
components in which the thematic maps were generated: geological, geomorphological,
pedological, hydrographic. The use of the NDVI tool indicated that the vegetation mass in the
course of the Correntinho stream is in several stages. At sample points 1 through 5 it is not
impacted, at point 6 impacted and at points 7 through 12 reasonably impacted. Regarding the
NDWI tool, they indicate that the wetlands identified in the Correntinho stream, including the
Veredas, are equivalent to 944 m² area, and in the application of the PARV it was verified the
geoenvironmental conditions of Veredas environment in Correntinho stream course, showing a
conservation level at some points in the stream, from the source to the middle course, at some
points anthropic interference and other parts that are still conserved but with early stages of
degradation. It was also possible to identify the importance of local Veredas as a fundamental
element in Cerrado biome that works to regulate the surface water flow, supply the underground
aquifer, and alsoas a source of income for local communities that make use of both extractivism
and crafts. In general, one can realize the importance of the research, demonstrating the
fundamental role of the Veredas of the Correntinho stream for the Cerrado and its
environmental conditions related to use and occupation. |
