    Abstract

    Devido às suas dimensões continentais e às condições ambientais dos trópicos (temperatura e umidade elevadas), o Brasil tem alta biodiversidade e grande potencial de produção de biomassa. A biodiversidade oferece uma grande variedade de produtos que podem ser explorados, tais como a biomassa vegetal, que pode ser utilizada como madeira para móveis e construção civil, fabricação de celulose (papel), lenha, carvão, combustível além de servir de matéria-prima para artesanato. Apesar disso, esse potencial produtivo é subutilizado no Brasil. O setor florestal brasileiro não aproveita sua biodiversidade, utilizando apenas monoculturas de espécies exóticas. Sua produção madeireira é pequena, considerando que se trata do país com a 2ª maior extensão de florestas do mundo. Este trabalho analisa a viabilidade da produção de biomassa vegetal (com enfoque especial para a madeira) na caatinga brasileira, bioma erroneamente considerado como pobre em biodiversidade e de baixa produtividade primária. O potencial de produção madeireira poderia ser aproveitado através de um plano de manejo adequado, com rotatividade de parcelas e gerenciamento integrada da biodiversidade.-----------------------------------------------Due to its continental dimensions and the tropical environmental conditions (high temperature and humidity), Brazil has high biodiversity and great potential of biomass production. The biodiversity offers a great variety of products that can be explored, such as the vegetal biomass, which can be used as wood for furniture and building construction, making cellulose for paper mill, firewood, coal, biofuel, besides serving as raw material for workmanship. The Brazilian forest sector does not take advantage of its biodiversity, only making use of the exotic species in monocultures. The Brazilian lumber production is low, considering that it is the country with the second largest forest area in the world. This paper analyzes the feasibility of the vegetal biomass production (with special emphasis to the wood) in the Brazilian caatinga, bioma mistakenly considered as poor in biodiversity and low primary productivity. The potential of lumber production could be taken advantage of an adequate management plan, with rotation of parcels and integrated management of the biodiversity.
