Planos de manejo florestais sustentáveis na Paraíba

Abstract

Of the forest resources available in the Brazilian Semi-arid, firewood and coal are the most used. The State of Paraíba points to a reality with a large dependence on firewood and charcoal as an energy matrix, both in the domestic and industrial sectors in its production processes. The Sustainable Forest Management Plans (PMFS) are a way to manage the use of forests in a conscious way, ensuring the sustainability of the ecosystem. As a result, it is used as a way to regulate the production of firewood and charcoal. This dissertation produced the characterization of the PMFS, the spatial distribution, the concentration study and the identification of clusters in Paraíba for the year of 2017. The objectives of the dissertation were: i) to analyze the profile, the groupings and the characterization of PMFS in Paraíba, ii) to analyze the concentration or how the PMFS behave in Paraíba, iii) to analyze the PMFS clusters using the Scan Statistic method. In order to achieve the objectives, the database was built through consultation from each PMFS; the characterization was developed through descriptive statistics; the concentration measures for importance evaluation and the Scan Statistics methodology were used to detect clusters in the study areas. The spatial distribution showed a higher number of PMFS in the Sertão and in the Borborema mesoregions. It was verified that the firewood production is higher in the mesoregions of Sertão Paraibano and of Borborema, while the charcoal has higher concentration in the Agreste Paraibano. And the Scan statistic identified a higher incidence of clusters in the Sertão Paraibano mesoregion, what is justified by the large number of PMFS in this area.
