“…The extensions of APPs devoid of native forest cover totaled 60% of the investigated area, when the major waterbed was considered, with cattle raising with secondary vegetation constituting the predominant land use in all sections of the Cabaçal River, with predominance in the middle course. The planted pasture was not identified in the upper course (Figure 3 A), a result similar to that found by Abrão et al (2018) in the APPs of the Desbarrancando River, in Mato Grosso do Sul, where about 68% presented vegetation cover and by Pinto and Rossete (2012) diagnosed that, in the micro-basin of the Córrego Capitão Décio, in Nova Xavantina MT, 88.53% of the APPs present preserved vegetation.…”

The parameter for delimiting Areas of Permanent Preservation (APPs) in the 2012 Forest Code is the edge of the regular stream bed, not its highest level. The objective of this study is to evaluate the loss of protected areas, framed the category of water APPs in the 2012 Forest Code, in the Cabaçal River. By means of spatial technologies, maps of vegetation cover and land use from 2012 and 2018 were prepared. The change in the Forest Code in 2012 caused the loss of 90% of the area previously protected by the 1965 Code, corresponding to the major waterbed of the Cabaçal River, especially in the lower course, located in the Pantanal plain of Mato Grosso. It was concluded that the vegetation cover in the Areas of Permanent Preservation was suppressed so that urban and agricultural uses could be implanted, characterizing them as conflict areas due to the flexibilization of the environmental legislation.

“…The hydrologically conditioned elevation model can have different purposes, such as morphometric characterization of watersheds, calculation of annual losses of soils, delimitations of permanent preservation areas along watercourses and hilltops, regionalization of flows, calculation of topographic factors and landscape units, and mapping of flood risk areas (Baena et al, 2004, Guimarães & Da Penha, 2009, Elebson et al, 2011, Pinto & Rossete, 2012, Coutinho et al, 2014.…”

A correct and accurate cartographic representation of the relief of watersheds is increasingly required due to the increased human actions on water resources. The objective of this work was to propose a conversion of the digital surface model (DSM) to the hydrologically conditioned digital elevation model (HCDEM) for the Marinheiro Stream Watershed in Sete Lagoas MG, Brazil, as a subsidy for hydrological and environmental analyses in this region. The methodology was developed in seven stages: a) Automatic classification of the Geoeye image; b) Ordinary kriging of the DSM points for areas without arboreous vegetation; c) Obtaining of the contour lines; d) Obtaining of points of exposed soil areas of the DSM and obtaining of the drainage network; e) Obtaining of the hydrologically conditioned digital elevation model (HCDEM); f) Correcting of the topographic profile of the drainage network region; and g) Analysis of the results. According to the results, the conversion of the model minimized the canopy effects and increased the coherence of the representativeness of the relief surface. The standard deviation found was 3.9 m, confirming the better performance of the HCDEM over the DSM, which presented a value of 4.95 m. Therefore, according to the validation points obtained in the field, the product of this study has a consistent basis for accurate and reliable hydrological, geomorphological, and geo-ecological analyses in the evaluated watershed.

“…Nesse sentido, essas áreas são de vital importância para proteger e prevenir desequilíbrios no meio ambiente. No entanto, alguns trabalhos científicos demonstram que há diversas situações de irregularidades entre a preservação da vegetação ciliar e o uso da terra (Cardoso;Aquino, 2013;Coutinho et al, 2013;Pinto;Rossete, 2012).Segundo Görgen (2009), essa situação deve-se também à falta de fiscalização e cobrança pelas autoridades para que essas áreas se mantenham preservadas, principalmente as áreas rurais, que muitas vezes estão localizadas em lugares de difícil acesso.…”

O presente trabalho tem por objetivo analisar a Área de Preservação Permanente (APP) do rio Santo Antônio, no assentamento colônia Santo Antônio frente às mudanças implementadas no chamado código florestal. Foram analisadas três áreas rurais situadas nesse assentamento, sendo consideradas de pequeno e médio tamanho. A área de estudo, bem como as áreas rurais e APP estudadas, foram delimitadas a partir do banco de imagens online no software Quantum GIS com licença de uso gratuita. Entre as imagens disponíveis nesse banco de dados, escolheu-se a do satélite GeoEye 1 de alta resolução espacial (1,65 m), obtida do complemento open layers plugin Google Earth. Os resultados demonstram que existem graves problemas no cumprimento da legislação florestal. Foram identificadas faixas de APP com ausência de vegetação ciliare, consequentemente, problemas erosivos, ou sendo usadas para cultivo de pastagem e dessedentação de animais.Ao final, foi proposta a recuperação desses locais, com técnicas de isolamento e recuperação atravésde plantio de vegetação arbórea nativa ou regeneração natural, bem como a implantação de projetos com a participação dos produtores rurais por meio de Sistemas Agroflorestais (SAFs).Palavras-chaves: APP, Código Florestal, Desmatamento, Recuperação.
