Abordagem cronológica e energética dos planos de manejo florestal sustentáveis da Caatinga

Abstract

The objective of this work was to analyze the real situation of Sustainable Forest Management Plans (PMFS) in Rio Grande do Norte (RN) based on temporal information from a database collected from 1989 to 2021, highlighting information on the use of firewood as a source of fuel. For this purpose, the database of Associação Plantas do Nordeste (APNE) and the Institute for Sustainable Development and Environment of Rio Grande do Norte (IDEMA/RN) was accessed, considering information on location, duration, volumetric production, Average Annual Increment. (IMA), zones of Average Annual Precipitation (AMP), cutting cycle and types of cutting being analyzed in a descriptive, quantitative and qualitative way, concluding that in 2021, only 28 PMFS had their active exploration license, occupying an area of approximately , 16,400ha, which corresponded to about 27% of the total area occupied by the protocoled PMFS. A total approved wood volume of approximately 212,000 st/ha-1 was also presented in the year 2021, which shows a drop of 60.08% in the authorized volume considering the data of the thirty-two years (assessed period). It was also observed that, despite the PMFS presenting a drop in the supply of firewood over the years, there is a tendency to recover forest management activities and this continues to be one of the great tools for conservation and sustainability.
