Última The legal reserve: historical basis for the understanding and analysis of this instrument Ciência Rural Santiago,Thaís Muniz Ottoni; Rezende,José Luiz Pereira de; Borges,Luís Antônio Coimbra. ABSTRACT: The revisions made in the Forest Code (FC) in 2012 appear to have promoted the weakening of the legal reserve (LR), which after at least 80 years of development, had become established in the Brazilian legal system as an instrument of environmental conservation. This study investigated the possibility of disruption in the implementation of the LR and was developed using qualitative approaches, including bibliographical and documental analyses, to assess the historical construction and legal format of the instrument over time. It was concluded that the current Forest Code broke the trend of development of the LR as an instrument of environmental conservation that was promoted by previous codes and removed the conditions necessary for its...

The Normalized Difference Vegetation Index (NDVI) is often used to extract information from vegetated areas since it is directly related to vegetation parameters such as percent of ground cover, photosynthetic activity of the plant and leaf area index. The aim of this paper was to analyze the potencial of semivariograms generated from NDVI values to detect changes in vegetated areas, analyzing their behavior (shape) and derived metrics (range, sill and nugget). Semivariograms were generated from NDVI values derived from Landsat TM images of May 2010, June 2010 and July 2011. The study area is located in the northern state of Minas Gerais, Brazil, and is covered by Brazilian savannas vegetation, totalizing 1,596 ha. Semivariograms were generated after the...
