Resumo: | The functionality of natural environments is altered by human actions at a rate more intense than that normally produced by nature itself. When unplanned, such changes provide a series of functional imbalances that often have drastic consequences on human life and nature itself. Examples of these environmental imbalances can be seen in most municipalities located in the semiarid Brazilian region. These, in the last decades have suffered with the improper implantation of new forms of use and occupation of the earth. Deforestation, the discharge of effluents into the waterways, the grounding and the construction in intermittent river channels denounce the lack of concern with land use planning. When considering the natural physical framework and the dialectical relations of land use and occupation of the Bahia north territory, this research aims to analyze the environmental vulnerability of the municipality of Senhor do Bonfim (BA) through geoprocessing techniques, in order to subsidize the development environmental. For this purpose, environmental vulnerability indexes were elaborated based on the integration of geological, pedological, clinographic and land use and occupation characteristics in a GIS environment. The results indicate the classes that present medium and high vulnerability include the inselberges and other residual reliefs. The low and very low vulnerability classes cover the tops of the pediplane located in the study area. The results allowed the understanding of the different degrees of vulnerability of each unit against certain anthropic pressures, and can be used as an instrument of local and regional environmental planning. |

Cuando no planificadas, tales cambios proporcionan una serie de desequilibrios funcionales que a menudo acarrean consecuencias drásticas a la vida humana ya la naturaleza misma. Ejemplos de estos desequilibrios ambientales pueden ser visualizados en la mayoría de los municipios situados en el semiárido brasileño. Estos, en las últimas décadas han sufrido con la implantación impropia de nuevas formas de uso y ocupación de la tierra. La deforestación, el lanzamiento de efluentes en los cursos de agua, la puesta a tierra y la construcción en canales fluviales intermitentes denuncian la falta de preocupación con el ordenamiento del territorio. Al considerar el cuadro físico natural y las dialécticas relaciones de uso y ocupación del territorio centro norte de Bahía, esta investigación objetiva analizar la vulnerabilidad ambiental del municipio de Senhor de Bonfim (BA) por medio de técnicas de geoprocesamiento, con el propósito de subsidiar el ordenamiento ambiental. En este propósito se elaboraron índices de vulnerabilidad ambiental a partir de la integración de las características geológicas, pedológicas, clínicas y de uso y ocupación de la tierra en ambiente SIG. Los resultados indican que las clases que presentan vulnerabilidad media y alta incluyen los inselberges y demás relieves residuales. Las clases de baja y muy baja vulnerabilidad abarcan los topes de los pediplanos situados en el área en estudio. Los resultados encontrados permitieron la comprensión de los diferentes grados de vulnerabilidad de cada unidad frente a determinadas presiones antrópicas, pudiendo ser utilizado como instrumento de ordenamiento ambiental local y regional.A funcionalidade dos ambientes naturais é alterada pelas ações humanas em um ritmo mais intenso que aquele normalmente produzido pela própria natureza.

O desmatamento, o lançamento de efluentes nos cursos de água, o aterramento e a construção em canais fluviais intermitentes denunciam a falta de preocupação com o ordenamento do território.
