The book "The Rural Environmental Registry in the Conservation of Natural Resources" by Felipe Monteiro provides a comprehensive analysis of the environmental impacts of land use in the Amazon region. It highlights the challenges posed by the conversion of primary forests into agricultural land and other uses. The author examines the role of the Rural Environmental Registry (CAR) as a tool for monitoring and protecting natural resources in Brazil. By evaluating CAR data and thematic land use products, two specific Amazon basins are analyzed, applying ecological principles and landscape metrics. The results show significant differences in the capacity for resource conservation between the studied areas and offer valuable insights into the importance of agricultural operations for conservation efforts.
