Resumo | Forest degradation is a long-term process that reduces forests biodiversity and impoverishes the ecosystems. Understanding the factors that generates and intensifies forest degradation, and its consequences, allows directing public policies to prevent this process. This study performed a spatial regression analysis between forest degradation intensity (dependent variable), environmental, political and economic variables in Novo Progresso (PA), a logging frontier expansion area in the Amazon Forest, from 2009 to 2011. The independent variables were related to fire occurrence, deforestation, conservation units, indigenous lands, logging poles and roads. The relationship between the dependent and independent variables (R2 and p-value) was individually tested, and the variables with the highest relationship were included in the regression model. Then, the variables with multicollinearity were excluded from the model with the stepwise backward technique. It was used the Moran test to detect spatial dependency on the data. Spatial dependency was detected with statistical significance (I = 0,2434; p-valor = 0 e z-score = 9,91), justifying the use of a spatial regression model. The Lagrange Multiplier test pointed out Spatial Lag Model as the best model adjusted to the data. The variables area of deforestation and total edge area explained 40% (R2 -adj: 0,4092) of the forest degradation intensity, indicating that fragmented forest and the forest areas closest to deforested areas are more likely to suffer higher degradation. For further studies, the R2 of the model can be raised by adding variables related to pasture expansion, forest management, colonization projects and updating the roads data yearly. |
