Abstract
Os empreendimentos florestais são considerados de elevado risco e de difícil gestão, ao passo que os investidores e empresas do setor precisam lidar não apenas com as flutuações do mercado, mas também com as possiblidades de sinistros ambientais que podem comprometer a produção da floresta. Considerando os desafios relacionados à gestão de negócios e recusos florestais, o objetivo da presente pesquisa foi analisar séries históricas e explorar métodos de análise de séries temporais para avaliar as perspectivas do mercado florestal e da conservação dos recursos florestais no Brasil. Para tanto, o trabalho foi desenvolvido em três capítulos definidos por metodologias e objetivos distintos: 1ª – utilizar o modelo ARIMA com intervenção para analisar as alterações na série histórica do desmatamento da Amazônia Legal frente a acontecimentos que são diretamente ligados à conversação da vegetação nativa; 2ª – avaliar o impacto das flutuações cambiais sobre as empresas brasileiras de papel e celulose de capital aberto utilizando a análise de cointegração e 3ª – comparar o método ARIMA com redes neurais em análises de séries temporais de produtos florestais brasileiros. Palavras-chave: conservação de recursos florestais; mercado de capitais; negócios florestais; séries temporais.
Forestry business are considered high risk and difficult to manage, while investors and companies in the sector need to deal not only with market fluctuations, but also with the possibilities of environmental accidents that could compromise forest production. Considering the challenges related to business and forest resource management, the objective of this research was to analyze historical series and explore time series analysis methods to evaluate the perspectives of the forest market and the conservation of forest resources in Brazil. To this end, the work was developed in three chapters defined by different methodologies and objectives: 1st – use the ARIMA model with intervention to analyze the changes in the historical series of deforestation in the Brazilian; 2nd – evaluate the impact of exchange rate fluctuations on stock value of brazilian cellulose and paper companies using cointegration analysis and 3rd – compare the ARIMA method with neural networks in time series analysis of brazilian forest products. Keywords: forest resources conservation; stock market; forest businesses; time series.
