SUMMARY:

Watersheds are natural areas considered important for territorial management. The
Pojuca River Basin (BHRP), located in the set of basins in the Recôncavo Norte region,
is considered a great environmental and socioeconomic symbol due to its natural
resources, which enable economic activity and other fundamental activities for society.
The objective of the research is to analyze the dynamics of land use and land cover
during the period from 1985 to 2020, in a period of 5 years, and the possible impacts on
water resources. For this, the basis of the applied methodology is related to the
acquisition of statistical data on the coverage and land use of MapBiomas images
through remote sensing techniques, and for the analysis of the Water Resource, the
delimitation of the APP of the rivers and analysis the average flow of the fluviometric
stations and vulnerability to water shock. For the characterization and understanding of
the observed area, analysis of demographic and socioeconomic data of each
municipality was carried out, in addition, the evolution of the cover classes and land use
of each one of them was supported, in order to understand how to proceed. changes in
these spaces comparing only the initial year (1985) and the final year (2020) of the time
series. In this 35-year space-time evaluation (1985-2020), the advance of the urban area,
forestry and pasture classes, which are currently the greatest threat to the integrity of the
BHRP's natural resources, was observed. Natural cover classes decreased such as
swamps (-24.2%) and forest formations (-6.9%), in addition to other natural covers such
as beach/dune areas (-78.9%) and water bodies (-58.33%). The evolution of the land
cover and use classes in the 22 municipalities of the BHRP and the spatial dynamics in
each one can be seen. use of land as in Aramari-BA, and also by urbanized areas as in
the case of Feira de Santana-BA. Regarding the analyzed Permanent Preservation
Areas, comparing the initial year (1985) with the end (2020) of the historical series,
there was an advance in the classes destined to land use, with emphasis on forestry
(100%), pasture (2%) and urbanized area (1003%). The spatiotemporal evaluation based
on the use of classifications on satellite images made available by the 6.0 collection of
the MapBiomas project, counts as being considerably alert to the threats that the uses of
space represent on the available natural resources.
