Resumo: | In Brazil there is a large availability of water resources, however the distribution of these resources does not occur in an equitable manner. Along with the issue of water scarcity, deforestation is revealed as another harmful environmental issue in river basins. In this context of problems, the São Francisco River basin is inserted, the largest hydrographic basin fully included in Brazilian territory. The geotechnologies based on the approach to landscape ecology enable assertive analyzes to manage areas with the problems of the São Francisco River basin. Thus, the objective of this work is to carry out a spatio-temporal analysis of land use and cover and size classes of forest fragments in the São Francisco River Basin, based on data from MAPBIOMAS, from the 1997s, 2007 and 2017. The mapping of land use and land cover was prepared using QGIS 2.18 software, as well as the calculation of the area and quantity of forest fragments that were divided into the following size classes: 1 - small (up to 10 ha); 2 - medium (between 10 and 100 ha) and 3 - large (greater than 100 ha). The results show that the hydrographic basin has undergone intense changes in its dynamics of land use and coverage and the structure of its forest fragments over 20 years, with emphasis on: areas of the Atlantic Forest with increased forest regeneration and large fragments; the agricultural frontier of Western Bahia and mesoregions of the São Franciscan Valley of Bahia and São Francisco Pernambucano with increased deforestation rates and small fragments; and an increase in forest maintenance spread in the Middle São Francisco, often associated with forestry. |

Dissertação (Mestrado em Desenvolvimento e Meio Ambiente) - Universidade Federal de Sergipe, São Cristóvão, SE, 2019.https://ri.ufs.br/jspui/handle/riufs/14482In Brazil there is a large availability of water resources, however the distribution of these resources does not occur in an equitable manner.

Juntamente com a questão da escassez hídrica, o desmatamento se revela como outra questão ambiental nociva nas bacias hidrográficas. Neste contexto de problemáticas se insere a bacia hidrográfica do Rio São Francisco, a maior bacia hidrográfica totalmente incluída em território brasileiro. As geotecnologias pautadas na abordagem na ecologia da paisagem possibilitam análises assertivas para gestão de áreas com as problemáticas encontradas na bacia hidrográfica do Rio São Francisco. Desta forma, o objetivo deste trabalho constitui-se em realizar uma análise espaço-temporal do uso e cobertura da terra e de classes de tamanho de fragmentos florestais da Bacia Hidrográfica do Rio São Francisco, a partir de dados do MAPBIOMAS, dos anos 1997, 2007 e 2017. O mapeamento de uso e cobertura da terra foi elaborado com software QGIS 2.18, bem como o cálculo de área e quantidade dos fragmentos florestais que foram divididos nas seguintes classes de tamanho: 1 – pequeno (até 10 ha); 2 – médio (entre 10 e 100 ha) e 3 – grande (maiores que 100 ha). Os resultados demonstram que a bacia hidrográfica sofreu intensas alterações em sua dinâmica de uso e cobertura da terra e estrutura de seus fragmentos florestais ao longo de 20 anos, destacando-se: áreas da Mata Atlântica com aumento da regeneração florestal e de fragmentos grandes; a fronteira agrícola do Oeste da Bahia e mesorregiões do Vale São-Franciscano da Bahia e do São Francisco Pernambucano com aumento de taxas de desmatamento e de fragmentos pequenos; e ainda aumento da manutenção florestal difundido no Médio São Francisco sendo muitas vezes associados a silvicultura.Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SESão Cristóvão, SEporGeoprocessamentoDesmatamentoAnálise espaço-temporalRecursos hídricosGeoprocessingDeforestationSpace-time analysisWater resourcesOUTROSAnálise espaço-temporal de uso e cobertura da terra na bacia hidrográfica do rio São Franciscoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPós-Graduação em Desenvolvimento e Meio AmbienteUniversidade Federal de Sergipereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.txtALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.txtExtracted texttext/plain108264https://ri.ufs.br/jspui/bitstream/riufs/14482/3/ALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.txtd4972a703a2b2c50b873930f9da6c2f2MD53THUMBNAILALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.jpgALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.jpgGenerated Thumbnailimage/jpeg1205https://ri.ufs.br/jspui/bitstream/riufs/14482/4/ALEXANDRE_HERCULANO_SOUZA_LIMA.pdf.jpg55ea90264dc2441cff28f86058eb4617MD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/14482/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALALEXANDRE_HERCULANO_SOUZA_LIMA.pdfALEXANDRE_HERCULANO_SOUZA_LIMA.pdfapplication/pdf2782066https://ri.ufs.br/jspui/bitstream/riufs/14482/2/ALEXANDRE_HERCULANO_SOUZA_LIMA.pdf183f48a1800605aa671faf3d17bd6d70MD52riufs/144822021-08-13 17:12:46.729oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2021-08-13T20:12:46Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
