Infográfico Sistema Agroflorestal Brasileiro

Um sistema agroflorestal (SAF) Ã uma estratÃgia de uso da terra que combina o cultivo de Ãrvores, arbustos e plantas com a agricultura ou a pecuÃria em uma mesma Ãrea. Esse mÃtodo promove a integraÃÃo sustentÃvel de elementos florestais e agrÃcolas, gerando benefÃcios econÃmicos, ambientais e sociais. Um resumo visual para representar um SAF pode incluir uma imagem que ilustra uma paisagem agrÃcola com Ãrvores intercaladas, mostrando a coexistÃncia de cultivos agrÃcolas e vegetaÃÃo florestal. Essa integraÃÃo beneficia a biodiversidade, a conservaÃÃo do solo, a captura de carbono e a produÃÃo de alimentos.
