A Reserva Legal é uma área localizada no interior das propriedades rurais, prevista no Código Florestal brasileiro, que deve ser protegida e apresentar coberta por vegetação natural, necessária à conservação, à proteção da fauna e flora e reabilitação dos processos ecológicos, além de servir como corredores ecológicos para o fluxo gênico das espécies. Muitas propriedades possuem estas áreas desmatadas, alteradas e em estágios avançados de degradação, tornando-se importante estudar o comportamento de plantios de espécies arbóreas de rápido crescimento com a finalidade de acelerar o processo de recomposição da vegetação natural e propor técnicas mais eficazes para recuperação destas áreas. Este trabalho teve como objetivo avaliar a influência da densidade do plantio homogêneo da Sclerolobium paniculatum Vogel, aos sete anos e meio de idade, como efeito catalizador do processo de regeneração. O experimento localiza-se na Fazenda Gênesis, Dom Eliseu, Pará. Avaliou-se o crescimento e verificou se a precipitação interfere no incremento diamétrico das árvores. Foram instaladas em blocos parcelas aleatórias com quatro repetições em cada tratamento. Para caracterização da composição florística, riqueza, diversidade e a similaridade da regeneração natural sob o plantio foram instaladas em cada tratamento (espaçamento), parcelas com oito repetições para três classes de avaliação da regeneração. E para caracterização da composição florística, riqueza, diversidade e similaridade do banco de sementes do solo foram instaladas aleatoriamente oito pontos de coleta do solo, com quatro repetições em cada tratamento, foram coletados quatro amostras compostas de oito e levadas para a casa de vegetação da Embrapa – CPATU onde foram dispostas em bandejas plásticas e regadas diariamente. Este experimento teve um período de quatro meses e a cada trinta dias as plântulas germinadas eram contadas e identificadas por um parabotânico. As árvores apresentaram maior altura no espaçamento 4m x 2m, maior diâmetro no espaçamento 4m x 3m, maior sobrevivência no espaçamento 4m x 4m. A regeneração natural apresentou maior similaridade na composição florística entre os espaçamentos 4m x 2m e 4m x 3m. Os valores da diversidade do índice de Shannon foram altos, não diferindo estatisticamente entre os espaçamentos. O banco de sementes mostrou maior riqueza de plântulas no espaçamento 4m x 3m, maior similaridade na composição entre os espaçamentos 4m x 2m e 4m x 4m. A diversidade das espécies em nível de 5% de significância não apresentou diferença entre os espaçamentos. Os resultados permitiram constatar que as áreas vêm sendo recuperadas e que algumas técnicas poderão ser aplicadas buscando reduzir custos e através de um manejo adequado poderá acelerar os processos ecológicos da regeneração natural.

The objective of this work is to compare how manifests the ideological positioning in the hegemonic media productions, according to Gramsci's conception, in relation to the radical alternative media, proposed by John Downing. The research has as opinionated content sample printed newspaper O Estado de s. Paulo, contrasting with the expressions of NON-PROFIT bauruense environmental “Instituto Ambiental Vidágua on the proposals of the new Brazilian forest Code. The analysis will hold in an interval between the adoption of the code by the Chamber of deputies in April 2012, and the provisional measure of President Dilma Rousseff with 32 modifications, after vetoing 12 articles proposed initially in may 2012. To support the study, will be crafted Gramsci hegemony; What is the alternative and radical media as it manifests itself; the relationship between the environmental journalism with the environmental NGOs; opinionated journalism and journalistic genres opinionated; theories of journalism and framing of matter

Historically the evolution of the occupation of ararense territory was due to the expansion of agricultural activities. Such activities were intensified with the transformations engendered by the Green Revolution, increasing the exploitation, the area occupied by agriculture and the deforestation and consequent environmental degradation. Therefore the current reality of rural areas in Araras/SP has shown that part of agricultural practices made it does not guarantee the effectiveness of environmental legislation and the sustainability of farms. Considering the recently implemented environmental policies, such as Law nº 12.651 / 2012, better known as New Forest Code and Decree nº 8.235 / 2014 establishing a period of one year to rural property registered with the Rural Environmental Registry (CAR), as tools targeting to reduce environmental degradation and contribute to building a sustainable rural development. This work aims to analyze the dynamics of the rural municipality of Araras on the environmental situation in some rural properties and actions to be taken by the owners to the full compliance of its properties before the environmental public policy

Due to the considerations on the Legal Forest Reserve, the aim of this paper is to show the distribution of the farming areas in the region and their application – especially natural forests. Also, to compare the municipal values with those stated in the Brazilian Forest Code in order to analyze the process of implementing 20% of forest area in relation to the total farming area, at municipal and regional levels, not considering the areas of each of the farms nor the watershed to which they belong with the Brazilian Forestry Code. The work results show that all municipalities in the region of Botucatu do not have forest areas equal or greater than 20% of total area. Therefore, a non-exploratory reforestation procedure will have to be implemented to follow legal requirements. Finally, the results show that the city of Areiópolis will face the greatest difficulties in implementing the 20% of forests with regard to the Legal Forest Reserve, until 2021, when the deadline stated by the Legal Code expires. According to the same variables, the municipalities of Anhembi, Conchas, Laranjal Paulista, Pereiras, Pratânia and São Manuel will face medium-level difficulties, whereas Bofete, Botucatu, Itatinga and Pardinho will implement it the easiest way.

The objectives of this study were to evaluate land use and occupation of Permanent Preservation Areas (PPA) as well as its use conflicts by TM (Thematic Mapper) image of the 2010 Landsat-5 satellite, according to the Forest Code. For that purpose, Geographic Information Systems in the Ribeirão Paraíso watershed, São Manuel, SP were used. The combination of Remote Sensing and Geographic Information System technologies allowed representation of spatial distribution of the landscape and data integration in the diagnosis of geographic interest. The 2010 mapping showed 12 use categories, and the sugar cane crop had the largest land occupation, 48.25% of the area. The areas of permanent preservation amounted to 925.74 ha, which is an ideal value based on the Brazilian legislation. Mapping of land use conflicts showed intensive anthropic actions going 80.13% forward on PPAs, with only 19.87% remaining forests, which highlights their negative impact and illegal situations in these areas.

The morphometric characterization of watersheds is of great importance in assisting the planning of these areas to preserve the environment and maintain the quantity and quality of water production. The aim of this study was to characterize the morphology and simulate the areas of permanent preservation according to the Brazilian Forest Code of watershed of the Água-Fria stream. The studied area is located in the municipality of Bofete-SP, between the geographic coordinates: 48° 09' 30" to 48° 18' 30" longitude (WGr) and 22° 58' 30" to 23° 04' 30" latitude S. The results showed a 5th order micro watershed with an area of 152.43 km2 and low drainage density of 1.04 km/km2. Circularity was 0.51 and form factor was 0.41, which is considered low, and therefore with an oblong/oval shape. The sinuosity index of 1.29 revealed a tendency of rectilinear channels with compactness coefficient value of 1.38 and distance of runoff flow of 520m. Simulation of areas of permanent preservation shows an ideal model as the way springs and watercourses should be protected according to the Brazilian Forest Code, amounting to an area of 10.02 km2.

This study aimed to recognize the significant temporal changes in land use between 1984 and 2008 in Barra Bonita City/ SP and to analyze the conflicts of land use in permanent preservation areas (PPA) with reference to the Forest Code and Resolution N. 303/2002 of CONAMA. The GIS Idrisi Andes 5.0 – geographic information system was used and the images were processed by LANDSAT TM5. Maps of land use were obtained by Maxver supervised classification and showed that in 1984 the area occupied by sugar cane crop was about 10.50 ha (70%) in 1984 and 10.90 ha in 2008. In analysis of conflicts about land use in permanent preservation areas showed that in 24 years the sugar-cane crops increased 3.6% on PPA. The occupation was represented by adequate forest of 279.25 ha (31.5% of total) in 1984. In 2008, the sugar-cane crop was the biggest conflict in PPA occupying 357.9 ha and 11.4% corresponds to areas in preparation for use. This year, 59.5% of total PPA is at odds with environmental legislation.
