Abordagem Sistêmica E Aplicação De Rugosidades Para Desencadear Propriedades Emergentes Em Restauração De Solos Degradados

Abstract: RESUMOBaseado na Teoria Geral dos Sistemas desenvolveu-se um modelo ecológico para a restauração dos ecossistemas, cujos solos estejam muito degradados, tratando o ecossistema como um sistema dinâmico complexo, hipersensível às condições iniciais de preparação do solo. Partindo da hipótese de que os ecossistemas degradados são sensíveis às condições iniciais de preparação do solo, avaliou-se a técnica das rugosidades (variações do relevo, alternando superfícies côncavas e convexas) para desencadear, ao longo d… Show more

“…According to Arthur et al (2014), concave, flat, and convex surfaces influence sediment production and intensity and direction of water flow in the soil profile. According to Aumond et al (2014), concave surfaces are characterized by microclimatic, topographic, and solar radiation conditions directed towards the interior, promoting greater concentration of matter and energy. Additionally, water, sediment, mineral, and organic matter accumulation can occur in this pedoform.…”

“…The convex pedoform showed different water dynamics in which the surface runoff of water and sediments was associated with the external and internal flow of matter and energy, leading to energy dissipation and losses caused by erosion and leaching (Aumond et al, 2014).…”

“…Thus, brushwood transpositioning is a technique capable of promoting roughness, not to modify its respective topography, but as elements that stand out horizontally and vertically in the local landscape. This roughness results in benefits for establishing soil fauna in degraded areas, mainly by attenuating the incidence of light and by conditioning a higher nutrient and humidity accumulation (Aumond et al, 2012;Aumond & Maçaneiro, 2014).…”

“…Outras medidas incluem a descompactação do solo (MINTER & IBAMA, 1990;Tasmania, 1999) e o aumento da rugosidade (ICMM, 2006; Australian Government Department of Resources, Energy and Tourism, 2011), por exemplo, através da escarificação de 20 a 30 cm de profundidade, seguida de gradagem (Bertol, et al, 2006;Silva, 2010). As técnicas de gradagem aumentam a rugosidade e a permeabilidade do solo, incentivando o estabelecimento da vegetação e evitando a erosão resultante de uma superfície compactada e lisa (Aumond & Maçaneiro, 2014). A gradagem deve ser realizada em toda a área, inclusive horizontalmente na face dos taludes (USEPA, 1972;MCA, 1998).…”
