Abstract
Além de um conjunto de elementos naturais e artificiais voltados ao equilíbrio ecológico, o Sistema Agroflorestal (SAF) é uma categoria espaço-temporal de base agrícola, pecuária e/ou silvicultural inseridas no contexto da microbacia hidrográfica que funciona como unidade espacial racionalizadora do trabalho, envolvendo recursos naturais e produção econômica, muito importante na recuperação, manejo e conservação da área de influência dos cursos d’água. O exemplo considerado é a microbacia do igarapé Açu, localizada no Estado do Pará, como representante do tipo hidrográfico amazônico, para a qual se propõe um diagnóstico sobre o estado atual e as tendências de disponibilidade e qualidade dos recursos naturais e agrícolas, para avaliação das interações dos fatores antrópicos com os naturais nas possíveis ameaças à integridade ecológica e da sustentabilidade social e econômica da área. Considerando a microbacia como unidade adequada ao planejamento, que reflete a região onde está inserida, e consolidada como categoria espacial ideal para o manejo de recursos naturais e avaliação de intervenções antrópicas. O SAF significa compatibilizar as necessidades das plantas com o uso do solo, minimizando a competição entre as espécies que substituirão a vegetação alterada por plantios com culturas perenes, que imitam as condições anteriores ao “processo degradador”, gerando um bosque maduro.-----------------------------------------------Beyond a set of artificial and natural elements directed to the ecological equilibrium. The Agroforestry Sistem (SAF) is a spatial-temporal category of the agricultural, livestock, or/and wood exploration inserted in the context of the hydrographic microbasin which works like rational spatial unit of the work that involve natural resource and economic production so important in the recovery, management and conservation of the area of the influence of the water flow. Where are agreed rural activities with the ecological sustainable to solve the resultant problems from revenue of the vegetal cover, soil erosion, water pollution and weakening of the other resource which reflect toward upon local population. The example to be followed is from Igarapé Açu microbasin sited in Pará State it represents the amazon hydrographic type in which we purpose a diagnosis about real moment and tendency availability and quality from the natural resources to evaluation of interaction of the anthropic factors with natural in possible threats to the ecological integrity and the social substantiality and economic are. Considering the microbasin as adequated unit to the planning that reflect the region where it is inserted and consolidated as ideal spatial category to the manage from natural resources and evaluation of the anthropic intervention. The SAF signifies to compatibly the necessities of the plants with use of the soil minimizing the competition among species that replace the vegetation altered by the planting of perennial crops that imitate the former condition to the degradation process generating a mature wood.
