Uso de geotecnologia na análise da dinâmica da eucaliptocultura para produção de carvão vegetal na região do Bico do Papagaio no estado do Tocantins

Abstract

The planted forest represents various products and by-products present in society, such as cellulose, paper, wood panels, laminate floors, charcoal and biomass, as well as offering various environmental services. In the State of Tocantins since 2007, there has been an intensification of projects related to forestry, mainly in the Bico do Papagaio region, for the purpose of producing charcoal as a renewable bioreducer, an input in the steel sector. This research aimed to analyze the dynamics of eucalyptus cultivation areas, in the Bico do Papagaio region. The acquisition and processing of satellite images with remote sensing techniques for the years 2006 and 2019, made it possible to identify the existing eucalyptus crops in each year. The physical, strategic and potential aspects of eucalyptus production in the region were also raised. With the overlapping of the cultivation areas identified in 2019 and the Ecological-Economic Zoning - ZEE - North of the State of Tocantins, the zones of influence were identified. The eucalyptus plantation area accumulated a significat variation in the analyzed period. Most of the areas are in areas with Quartzarenic Neossols, requiring adequate forest management. The agroclimatic suitability for culture in the region indicated marked water restriction. The region has favorable transport logistics in relation to the main modes. The ZEE pointed out that most crops are in areas of ecological corridors, which can be positive if well planned. Studies of regional agroenergetic potentials are fundamental to the development of the Eucalyptus species in the region.
