Potential and emerging fragility in the Peruaçu river basin, northern region of Minas Gerais

This study was aimed at mapping the potential and emerging fragility of the Peruaçu River Basin based on the methodology proposed by Ross (1994). The Peruaçu River Basin is located in the Northern region of Minas Gerais, covering an area of 1552.3 km². Furthermore, from the maps overlapping, such as...

The Peruaçu River Basin is located in the Northern region of Minas Gerais, covering an area of 1552.3 km². Furthermore, from the maps overlapping, such as slope, rainfall erosivity, soil types and soil use and cover, it was possible to map the environmental fragility. The fragility was classified into five different levels: Very Low, Low, Mean, Strong and Very Strong. As a result, for the potential fragility, it was predominant the high fragility, covering 56.88% of the area. On the other hand, in the emerging fragility analysis, it was observed the predominance of mean and high fragility classes with 37.22% and 36.83%, respectively. Moreover, the results obtained indicate the need of recovering degraded areas and the implementation of soil conservation techniques in areas of greater fragility. O presente trabalho teve como objetivo mapear a fragilidade potencial e emergente na Bacia do Rio Peruaçu, com base na metodologia proposta por Ross (1994). A Bacia do Rio Peruaçu está localizada na Região Norte de Minas Gerais, cobrindo uma área de 1.552,3 km². A partir da sobreposição de mapas de diferentes atributos, tais como, declividade, erosividade da chuva, tipo de solo e uso e cobertura do solo, foi possível mapear a fragilidade ambiental. A fragilidade foi classificada em cinco diferentes níveis: muito fraca, fraca, média, forte e muito forte. Como resultado, para a fragilidade potencial predominou a classe de alta fragilidade com 56,88% (882,9 km²) da área. Enquanto que, na análise da fragilidade emergente, observou-se a predominância das classes de Alta e média fragilidade, com 37,22% (577,71 km²) e 36,83% (571,73 km²), respectivamente. Os resultados obtidos evidenciam a necessidade de recuperação das áreas degradadas e a implantação de técnicas de conservação do solo nas áreas de maior fragilidade.
