Sabendo das crescentes preocupações ambientais no setor florestal, a utilização da tração
animal é vista como um contributo mais favorável para o ambiente em comparação a tração
mecânica. Dessa forma, o presente estudo teve como objetivo analisar o uso da tração animal
em três diferentes cenários de manejo florestal por meio da análise de ciclo de vida, uma
ferramenta de extrema importância para se estimar os impactos ambientais relacionados à um
processo ou produto. Dados primários foram adotados de uma atividade prática realizada em
campo e que serviu de base para a elaboração dos cenários de manejo florestal utilizando a
tração animal, a tração mecânica e uma opção mista. A pesquisa revelou que a tração animal
proporciona uma notável redução de 56% nas emissões de CO2 em comparação com a tração
mecânica, devido à sua menor dependência de combustíveis fósseis. Os resultados estimam-se
que o cenário com a tração animal e o cenário misto mecanizado-animal, contribuíram em
menor quantidade para cinco, das seis categorias analisadas, e, o cenário que apresentou o
melhor desempenho ambiental dentro do manejo florestal foi o de tração animal. Contudo, a
tração animal apresenta desafios, como a dependência de animais e limitações na capacidade
de carga. Para mitigar essas limitações, destaca-se a integração de um sistema misto,
combinando tração animal e tratores, como uma abordagem equilibrada para reduzir os
impactos ambientais. Além disso, enfatizamos a transição para o uso de biodiesel em máquinas
florestais como uma estratégia eficaz na redução das emissões de gases de efeito estufa.
Independentemente da escolha de abordagem, a gestão florestal sustentável continua sendo
essencial.
vi ABSTRACT In light of the escalating environmental concerns within the forestry sector, the utilization of animal traction is regarded as a more environmentally favorable contribution in comparison to mechanical traction. Accordingly, the present study aimed to scrutinize the utilization of animal traction in three distinct forest management scenarios through life cycle analysis, a tool of paramount significance for estimating environmental impacts associated with a given process or product. Primary data were derived from a field-based practical activity, forming the foundation for crafting forest management scenarios involving animal traction, mechanical traction, and a mixed option. The research unveiled that animal traction yields a noteworthy 56% reduction in CO2 emissions as opposed to mechanical traction, attributable to its diminished reliance on fossil fuels. The findings postulate that both the animal traction scenario and the mechanized-animal mixed scenario made lesser contributions to five out of the six analyzed categories. Notably, the animal traction scenario demonstrated the most commendable environmental performance within the domain of forest management. Nevertheless, animal traction poses challenges, such as reliance on animals and limitations in load capacity. To alleviate these constraints, the integration of a mixed system, amalgamating animal traction and tractors, is underscored as a judicious approach to curbing environmental impacts. Furthermore, we underscore the transition to the use of biodiesel in forestry machinery as an efficacious strategy in abating greenhouse gas emissions. Irrespective of the chosen approach, the imperative of sustainable forest management remains unabated.
