Ribeira Valley, a region covered by the last continues area of the Atlantic Rain Forest in São Paulo State, in Brazil, is thus a preservation law and environmental control target, is now configurated as locus where emerge conflicts concerning economic and agricultural activities, particularly in places where befall public policies recognizing territorial rights – quilombo remnants, indigenous lands and sustainable development settlings. The research’s aim is to understand, considering each of these contexts, if and how a conservationist focus is assumed as a value and a strategy, connected to etnicity and traditionality, in order to actualize these social spaces.

Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

The permanent preservation areas (PPA) established by Brazilian law are there to protect the natural environment. With the expansion of space occupied by man and development of economic activities in these areas were engaged in conflicts characterized PPA, where the use is other than the natural vegetation. According to these paradigms work aims to raise these conflict areas in the River Basin Capivara, Botucatu (SP) with the help of GIS Ilwis 3.4, topographic maps of IBGE and satellite images CBERS 2B. The map was generated from PPA in the GIS by distance calculation in relation to drainage, springs and break line on Cuesta de Botucatu. The classes of land use and natural vegetation were determined by interpretation of satellite images and field visits to check their veracity. With the cutting of the map of land use and natural vegetation in relation to PPA unit it was determined that the total 44,63% PPA is in conflict occupied by pasture, forest plantation, orange, annual crops, farms and irrigated rice project in lowland. This diagnostic characterizes the degradation of the environment and highlights the need to harmonize the economic and urban development with the preservation of the environment to ensure sustainability of the region.

There is a demand to incorporate the nature in the city in order to meet the wishes of the entire population. The valuation of water, a key component of the quality of the landscape, becomes a key element in this context both for its ecological potential because of their potential for recreational activities. The areas that suffer most impacts are the Permanent Preservation Areas (PPAs) and this paper will be a weighting on the urban interface - PPA. With the study area the basin of the stream of Limoeiro, in the context of the Friendship Fountain Balneary, especially the source contained between residential neighborhoods Maré Mansa and Parque Imperial, the city of Presidente Prudente and Álvares Machado, Sao Paulo, this paper aims to search and use of knowledge about technologies and techniques of environmental restoration, with emphasis on bioengineering, through an environmental characterization of the basin, with a view the incorporation of nature in the lives of the urban population. The methodology includes: literature review priority issues related to the PPAs, linear parks, relevant environmental legislation, environmental characterization of the watershed of the stream Limoeiro; study of technologies and techniques for environmental remediation of soil bioengineering and implementation of parks linear, development of proposals for the environmental recovery of PPA in the basin of the stream Limoeiro, focusing on emerging...

O Litoral Norte do Estado de São Paulo compõe uma região estratégica, notada pela importância de suas Áreas Protegidas (AP), sobretudo, pela presença humana em Unidades de Conservação (UC), um tema cada vez mais presente no debate sobre a proteção ambiental em territórios ocupados por grupos tradicionais que exercem uso diferenciado dos recursos naturais. Diante desse contexto, torna-se uma necessidade, viabilizar diretrizes para a gestão territorial ao possibilitar o compartilhamento das decisões acerca do uso do território, visando à conservação ambiental e proteção da cultura remanescente dos grupos sociais residentes no interior das UC. O presente trabalho busca dimensionar os aspectos de interação com o ambiente, através das formas de uso mantidas sobre os recursos naturais, como característica de reprodução sociocultural, premissa à proteção e manutenção do modo de vida das famílias residentes do Núcleo Picinguaba do Parque Estadual da Serra do Mar no município de Ubatuba-SP. No intuito de compatibilizar diretrizes para o planejamento da UC, evidenciou-se a relação da formação histórica da área, tal como, a interação exercida sobre ao ambiente e a resistência territorial, ao abordar a questão cultural e o modo de vida dos residentes tradicionais da Zona Histórico-Cultural Antropológica (ZHCAn) do Sertão do Ubatumirim. Foram sistematizadas informações para uma abordagem teórico-conceitual a respeito da cultura tradicional caiçara e do recorte geográfico do território, possibilitando a compreensão da dinâmica de produção do espaço em uma área ambientalmente protegida. A partir dessa caracterização da área foram indicadas zonas prioritárias ao planejamento territorial, voltado ao ordenamento ambiental e à gestão do uso dos recursos naturais em uma abordagem diferenciada na relação do ordenamento para as áreas...
