Item Acesso aberto (Open Access) O valor econômico da extração manejada de madeira no baixo Amazonas, estado do Pará(2012-06) SANTANA, Antônio Cordeiro de; SANTOS, Marcos Antônio Souza dos; SANTANA, Ádamo Lima de; YARED, Jorge Alberto GazelThe objective of this study was to estimate the economic value and the trade margin of roundwood from managed areas. Besides generating a positive margin values, they are relatively higher In this chain than those generated in activities contributing to deforestation in the Amazon. Additionally, the unfolding mean rate of 37.3% was achieved (2.68 m3 of logs for each 1.0 m3 of sawn timber), which revealed a low technological level of companies. At the lower Amazon, the average economic value from the extraction and sale of standing timber in the local market was R$ 23.48/m3, with a minimum value of R$ 9.06/m3 for the species in category C4 (softwood) and a maximum of R$ 55.63/m3 for the species of category C1 (special wood). Thus, considering an extraction flow of 30 years and assuming the extraction of 25 m3/ha in management designs of forest areas from concession contracts in the state of Pará, it is generate an average economic value of R$ 587.00/ha or R$ 19.56/ha/year, which is relatively higher than the profit generated by the activities of extensive livestock (around R$ 180.00 per hectare or R$ 6.00/ha/year) and grain crops (approximately R$ 420.00 per hectare or R$ 14.00/ha/year), which are the main responsibles for deforestation in the Amazon. It also presents a higher profitability than the reforesting with Paricá, whose income is R$ 192.26/ha or R$ 7.12/ha/year. The marketing margin showed that society tends to appropriate of 14.30% of the economic value generated in the wood chain from the transition contracts.
