Quantificação do estoque de carbono e avaliação econômica de diferentes alternativas de manejo em um plantio de eucalipto Fausto Araújo Paixão Carlos Pedro Boecha Soares Laércio Antônio Gonçalves Jacovine Marcio Lopes da Silva Helio Garcia Leite Gilson Fernandes da Silva Agrociencias Seqüestro de carbono uso múltiplo e eucalipto Este estudo teve por objetivos: quantificar o estoque de madeira para a produção de carvão eserraria em uma floresta de eucalipto; quantificar o estoque de carbono nos diferentes compartimentos dafloresta; e avaliar economicamente alternativas de manejo, com vista à inserção de povoamentos florestaisno mecanismo de desenvolvimento limpo e na venda de créditos de carbono. Para isso, realizou-se um inventárioflorestal em uma plantação de Eucalyptus grandis, com 6 anos de idade, no Município de Viçosa, Minas Gerais.Após as análises, verificou-se que: a) o fuste é o componente da árvore que mais contribui, em média, parao total de carbono da parte aérea (81,84%), seguido por casca (8,05%), galhos (7,74%) e folhas (2,57%);b) 47,7 toneladas de carbono por hectare estão estocadas na parte aérea das árvores; 14,71 nas raízes e 8,72na manta orgânica, totalizando 71,13 toneladas de carbono por hectare; c) a produção de madeira somentepara a venda de créditos de carbono, sem considerar o seu uso final, é economicamente viável, segundo critériosquantitativos de avaliação do projeto, se a tonelada de carbono for comercializada a preços maiores que US$10,07; e d) a venda de créditos de carbono torna o empreendimento ainda mais atrativo economicamente,sobretudo porque a receita é auferida no início do projeto. 2006 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48830311 pt http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.3 Vol.30
