MOREIRA, F. M. S. Brazilian Forest Code: methods of allocation of legal reserves and comparison of law’s changes proposals. 2011. 117 p. Dissertation (M. Sc.) – Escola de Engenharia de São Carlos, Universidade de São Paulo. São Carlos, 2011. In Brazil, the first version of Forest Code in 1934, created by the Decree 23.793, and latter the New Forest Code (FC) in 1965 (Law 4.771) shows the concerns of the society for the rational use of national territory. Concerning to the management and conservation of natural resources, the present FC establishes two important conservation tools: Permanent Preserved Areas (PPA) and the Legal Reserves (LR). The PPA’s location is immutable and the LR can be located in different ways, according to criteria defined by Federal Law and complemented by the States. The general criteria for LR location can, however, create subjectivities. It becomes clear the needing of searching more precise instruments for achieving its goals. For that, researches have been done to help decision makers to define LR`s location, intending to achieve properly its functions of sustainable use of natural resources and biodiversity conservation. Although the historical advances obtained in Brazil with the FC, it can deeply retrocede if the Law Project 1876-C/99 (LP), presented and approved by the Congress and sent to Senate as LP 30/2011, became approved. The LP proposes significant reductions on the PPA and RL dimensions, as well as facilitates the non obligation of law’s application. This fact has sparked contestations of the science community, represented by the Sociedade Brasileira para o Progresso da Ciência (SBPC) and the Academia Brasileira de Ciências (ABC), that says only short term economical components were considered on the LP, desconsidering environmental components and neglecting the support of science and technology knowledge when rewriting such important law for the society, as the FC. This research’s goals are to analyze methods for LRs location and to compare different views of changes on FC. For that, were defined two specific goals: 1 – Apply three methods for LR’s location according to the FC, considering the possibility of compensation of LR between properties, intending to identify witch method better achieve the LR functions. 2 – Elect one of the tested methods and create scenarios to compare the FC directions with the proposals presented to its review suggested by the LP 1.876-C/1999 (and LP 30/2011) and the SBPC/ABC. The scenarios were designed for the São Carlos city located on São Paulo State, the GIS used was IDRISI and the software used to calculate the landscape metrics was the FRAGSTATS. The results shows that: easy application methods can help on the definition of LR’s location in manner to achieve its goals; the LP would bring strong negatives consequences for the biodiversity, soil and water resources conservation, and, for that, its reviewing should be postponed and properly supported by society and scientific community participation.
