Avaliação da sustentabilidade dos sistemas florestais em função da erosão

Abstract

A sustentabilidade de um sistema depende em primeira análise da sua capacidade de não ultrapassar a resiliência de qualquer dos elementos que o compõem. Assim, o risco de erosão, a susceptibilidade e a tolerância à perda de solo aferem a sua resiliência aos factores externos, sendo uma medida da manutenção do potencial produtivo do sistema. Com base na Equação Universal de Perda de Solo foi desenvolvido um modelo de risco de erosão, que posteriormente foi implementado tendo em conta a tolerância à perda de solo, de acordo com a metodologia da FAO, que considera a profundidade do solo e as características do material originário, integrando a informação ao nível de um sistema de informação geográfica. Este trabalho deu origem ao desenvolvimento de uma metodologia de aferição da sustentabilidade do sistema florestal em função das características do solo e do coberto florestal. Assim, foi possível avaliar a manutenção do potencial produtivo dos sistemas florestais.
