Abstract

ABSTRACT This paper analyzed the disparity in the gross production value of timber products from the state of Paraíba, Brazil, between 1994 and 2017. The indicators used were: the locational quotient (Lq), the coefficient of location (Cl), the coefficient of redistribution (Cred), the coefficient of geographic association (Cga), the coefficient of specialization (Cs) and the coefficient of restructuring (Cr). The results obtained indicated that wood was the main timber product extracted in the state of Paraíba, with the Sertão paraibano region being of greater relevance, increasing the disparity between the regions; the Cred pointed out greater change for charcoal extraction; the Mata Paraibana region was the most specialized region, especially for wood extraction; and the Borborema region presented the greatest restructuring in all studied periods. The study evidenced that the extraction of wood products mainly occurred in the more arid regions of the state with the purpose of population subsistence or industrial use, especially in the red ceramics and plaster segments for which wood can be used to generate heat and thermoelectric power.

Highlights

Forest products come from planted or native forests and can be classified as timber or nontimber

Timber comes from woody material divided into industrial wood, firewood and charcoal, and processed woods, while nonwood products are all biological goods extracted from forests or wooded areas except wood (Food and Agriculture Organization of the United Nations - FAO, 1999; FAO, 2018; Instituto Brasileiro de Geografia e Estatística – IBGE, 2017)

Summary

Introduction

Forest products come from planted or native forests and can be classified as timber or nontimber. Timber comes from woody material divided into industrial wood, firewood and charcoal, and processed woods (chips, slats and plates), while nonwood products are all biological goods extracted from forests or wooded areas except wood (Food and Agriculture Organization of the United Nations - FAO, 1999; FAO, 2018; Instituto Brasileiro de Geografia e Estatística – IBGE, 2017). In 2017, Brazil had a gross production value (GPV) of R$17.22 billion for timber products (16.16% of plant extraction and 83.84% of forestry). National vegetal extraction was distributed into 69.17% (R$1.92 billion) of roundwood, 19.43% (R$54.09 million) of firewood and 11.40% (R$31.72 million) of charcoal. The main timber product was roundwood in the NO and MW, and firewood in NO, SO and SE (IBGE, 2018)
