GEOPROCESSAMENTO APLICADO NO DIAGNÓSTICO DOS CONFLITOS DE USO E OCUPAÇÃO DO SOLO EM ÁREAS DE PRESERVAÇÃO PERMANENTE NO RIBEIRÃO DAS AGULHAS – BOTUCATU (SP)

Sérgio Campos et al.

Resumo


As áreas de preservação permanente (APP) têm função ambiental de preservar os recursos naturais, a biodiversidade, o fluxo gênico da fauna e flora, o solo e a segurança do bem-estar das populações humanas. Enquanto que a degradação das matas ciliares contribui para o assoreamento, elevação da turbidez da água e para a erosão das margens dos cursos d'água, transportando substâncias poluidoras, como defensivos e fertilizantes agrícolas. O trabalho visou determinar o uso inadequado das áreas de preservação permanente da microbacia do Ribeirão das Agulhas – Botucatu (SP), tendo como base cartográfica, a carta planialtimétrica de Botucatu e a imagem de satélite de 2011. A metodologia consistiu no uso do SIG-IDRISI Selva para realização do georreferenciamento da imagem, geração dos buffer de APPs e o overlay na obtenção dos conflitos de uso e ocupação em APPs. O grande uso da microbacia correspondeu às pastagens com 675,34ha. As APPs (166,10ha) estão sendo usadas inadequadamente por 93,33ha com pastagens. O diagnóstico dessas áreas da microbacia indica a necessidade de uma intervenção vinculada ao plano de proteção ambiental para a recuperação das áreas degradadas e consequentemente permitir uma regeneração da cobertura natural das APPs que estão sendo utilizadas sem respeitar a legislação ambiental brasileira. As ferramentas de geotecnologias foram imprescindíveis para obter o diagnóstico do uso e ocupação do solo em APPs da área.

GEOPROCESSING APPLIED IN THE DIAGNOSIS OF CONFUSED GODS AND SOIL OCCUPATION IN AREAS OF PERMANENT PRESERVATION IN THE STREAM OF THE AGULHAS - BOTUCATU (SP)

ABSTRACT
The permanent preservation areas (PPA) have environmental function of preserving natural resources, biodiversity, gene flow of fauna and flora, the soil and the safety of the well-being of human populations. While the degradation of riparian forests contributes to silting, water turbidity increase and the erosion of the banks of waterways, carrying pollutants, such as pesticides and agricultural fertilizers. The objective of this work was to determine the inadequate use of the permanent preservation areas of Stream of the Agulhas - Botucatu (SP) microbasin, based on cartography, Botucatu planialtimetric chart and satellite image of 2011. The methodology consisted of the use of SIG-IDRISI Jungle to perform image georeferencing, generation of PPA buffer and overlay in obtaining conflicts of use and occupation in PPA. The great use of the microbasin corresponded to pastures with 675.34ha. PPA (166, 10 ha) are being used inadequately for 93.33ha with pasture. The diagnosis of these areas of the microbasin indicates the need for an intervention linked to the environmental protection plan for the recovery of the degraded areas and consequently to allow a regeneration of the natural coverage of the PPA that are being used without respecting the Brazilian environmental legislation. The geotechnology tools are essential to obtain the diagnosis of land use and occupation in PPA in the area.

SIG APLICADOS EN EL DIAGNÓSTICO DE CONFLICTOS DE USO Y OCUPACIÓN DEL SUELO EN ÁREAS DE PRESERVACIÓN PERMANENTE EN EL RÍO DE LAS AGULHAS – BOTUCATU (SP)

RESUMEN
Las Áreas de Preservación Permanente (APP) tienen una función ambiental para preservar los recursos naturales, la biodiversidad, el flujo genético de fauna y flora, el suelo y la seguridad del bienestar de las poblaciones humanas. La degradación de los bosques ribereños contribuye a la sedimentación e incremento en la turbidez del agua, a la erosión de las orillas de los cursos de agua y al transporte de sustancias contaminantes, como pesticidas y fertilizantes agrícolas. El trabajo tuvo como objetivo determinar el uso incorrecto de las áreas de preservación permanente de la cuenca del río das Agulhas – Botucatu (SP), basada en la carta planialtimétrica de Botucatu y la imagen de satélite de 2011. La metodología consistió en el uso de GIS-IDRISI Selva para la georreferenciación, la generación de los amortiguamientos de las APPs y la superposición de los conflictos de uso y ocupación. El gran uso de la cuenca se correspondió con pastizales, 675,34ha. Las APPs (166,10ha) se utilizan inadecuadamente, con 93, 33ha de pastizales. El diagnóstico indica la necesidad de un plan de protección vinculado al medio ambiente, y destinado a la recuperación de áreas degradadas, que permita la regeneración de la cubierta natural de las APPs, que se utilizan sin cumplir con la legislación ambiental brasileña. Las geotecnologías fueron herramientas indispensables para el diagnóstico del uso y ocupación del suelo en el área analizada.
