As políticas públicas ambientais e a dinâmica do espaço rural no município de Araras (SP)

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

Evolução da área florestada na região de Botucatu/SP no período de 1996 a 2008 visando à implantação da Reserva Legal

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.

Utilização de imagem de satélite Landsat no mapeamento da ocupação da terra e seus conflitos de uso em APPs na bacia hidrográfica do ribeirão Paraíso - São Manuel (SP)

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.

Análise morfométrica e simulação das áreas de preservação permanente de uma bacia hidrográfica

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.

Cultivo da cana-de-açúcar e o uso do solo em áreas de preservação permanente

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.

Avaliação da adequação da ocupação do solo em áreas de preservação permanente (APPs)

Evaluation and adequacy of land occupation in Permanent Preservation Areas (PPAs) are important to ensure quantity and quality of water and local biodiversity. The objective of the study was mapping PPAs according to the Brazilian Forest Code and quantifying land cover and use, establishing the conflict of PPAs occupation in the Ribeirão Lavapés sub watershed. The area is 11,154.58 ha, and is located in Botucatu city, Midwestern region of São Paulo state. For this reason, geoprocessing tools, such as Remote Sensing and the Geographic Information System (SIG) were used. The dominant classes of land use and cover were the Urban Zone in Reverse Cuesta, 4,394.27 ha (39.39%) and Annual Crops in the Peripheral Depression, 3,670.89 ha (39.39%). The mapped area of native forest vegetal cover in the sub watershed was of 1,109.70 ha. Regarding the mapping of PPAs, considering the total area of 1,721.80 ha, a total of 532.15 ha (30.91%) are covered by Riparian Forest and 1,189.65 ha (69.09%) had no native riparian vegetation, therefore, requiring its reforestation.

Áreas de preservação permanente (APP) na sub-bacia hidrográfica do córrego do Marimbondo, Jales (SP): um estudo das condições ambientais

This work aimed to carry out a study of the environmental conditions of the Permanent Preservation Areas (PPAs) in the sub-basin of Marimbondo Stream in the city of Jales (SP), through remote sensing techniques and taking as the basis Brazilian environmental legislation, the Forest Code Federal Law Nº 12,651/2012. Permanent Preservation Areas are inserted intrinsically improved conditions in the quantity and quality of water in the areas of springs and along water bodies in rural properties. Therefore, we also carried out studies on the new Forest Code compared to the old Federal Law Order no. 4771/1965 and the observation of its application in the area of sub-basin as well as carrying out the simulation. The results of this research allowed toverify the need for direct implementation of the monitoring measures with the Forest Code, and this water management tool in Brazil, which will ensure sustainable management practices of land use and land cover, with direct benefits to water production, mainly for public supply. Also there was a greater need for involvement by the public actors, the Basin Committee of the São José dos Dourados and the municipal government of Jales, in order to truly act aimed at the protection and maintenance of the water body Stream Wasp
