As Unidades de Conservação são sub-divididas em duas categorias: Proteção Integral, com objetivos de manutenção do ecossistema livre da interferência humana na qual é permitido apenas o uso indireto; e de Desenvolvimento Sustentável, que tem por objetivo equilibrar a conservação da natureza com o uso sustentável dos recursos naturais. O Parque de Jacupiranga era localizado na região sul do estado de São Paulo, denominada Vale do Ribeira, sendo criado em 1961 com aproximadamente 141 mil ha e cerca de 8 mil moradores presentes no seu interior, incluindo comunidades tradicionais, quilombolas, e agricultores migrantes de outros estados. O mosaico de Jacupiranga foi criado em 2008, com o objetivo de atender reivindicações dos moradores que sofriam restrições de suas atividades por estar dentro de uma unidade de conservação de proteção integral, com isso, o antigo PEJ sofreu a recategorização, e foram criadas 3 unidades de proteção integral e 7 de uso sustentável na antiga área do parque. O objetivo foi analisar as mudanças socioeconômicas e ambientais das famílias que sofreram com a recategorização do antigo Parque Estadual do Jacupiranga para a Reserva de Desenvolvimento Sustentável (RDS) dos Quilombos de Barra do Turvo e a Área de Proteção Ambiental (APA) do Planalto do Turvo, Mosaico de Jacupiranga/SP, onde a legislação ambiental permite a presença de moradores bem como suas atividades de subsistência. A coleta de dados foi feita pelo processo de entrevistas estruturadas realizadas com 12 moradores escolhidos por indicação dos próprios moradores das áreas tanto da APA quando da RDS. Com isso, pode-se observar uma maior liberdade nas atividades de uso da terra praticadas pelos moradores, contudo, mesmo com a recategorização, os investimentos públicos locais não são suficientes para propiciar uma boa qualidade de vida para as famílias das áreas analisadas

The Federal Constitution of 1988 gave special treatment to the issue of the environment, raising this diffuse right to the status of a fundamental right. In order to preserve it, the constitutional order is provided with various means to this purpose, including the possibility of using taxation. Several principles both constitutional, as infraconstitucional, support the use of taxation as a legal instrument to protect the environment. There is an intense legal debate about the suitability, characteristics, purposes and principles which underlie and restrict the environmental taxation. Discussions and proposals for reform of the tax system in order to include the ecological aspect at its core have been developed. The use of taxation as a way to fund public expenditures related to environmental causes, promote the internalization of negative externalities and as a way to induce behavior to benefit the environment finds support in the Brazilian legal system. This paper seeks to demonstrate that the national tax system is fully able to act as a tool available to the state for the implementation of the fundamental right to an ecologically balanced environment, whether through the taxes fiscal role or due, mainly, through the phenomenon of extrafiscality. Also, it is intended, through doctrinal, jurisprudential analysis and concrete cases, to investigate whether the tax system can be effective in protecting the environment in the way it is currently constructed, or if there is need to proceed with changes in its structure in order to achieve this goal

The Área de Proteção Ambiental de Jenipabu was created by Decreto 12,620/95, covering the beaches of Redinha Nova, Santa Rita and Jenipabu and Campina communities in the municipality of Extremoz, and Africa community fragment, in Natal. This protected area was created in the context of expansion of tourism in Rio Grande do Norte, in the 1990s, in which PRODETUR investments made possible the installation of infrastructure equipment, mainly in the Via Costeira and Ponta Negra beach in Natal by inserting it in the sun and sea tourism route to Northeast Brazil. In this context the beach Jenipabu in Extremoz, became one of the main attractions for those visiting Natal, due to the natural elements of its landscape, its dune field, which is offered to tourists the buggy ride. In December 1994 the excess buggy rides held in these dunes led to IBAMA ban their access to buggy for carrying out environmental study. This measure resulted in the creation of APAJ in 1995 with the goal of ordering the use and occupation to protect its ecosystems, especially the dunes, the disordered tourism. Given this context, this work aims to analyze the process of creating the APAJ and changes in the geographic space of its beaches, Redinha Nova, Santa Rita and Jenipabu, from the materialization of tourism process, as well as their implications for its residents. To this end, this paper presents a discussion of environmental currents that developed in the western portion of the globe, focusing on the need to regulate small areas of the national territory in protected areas, and an analysis of public policies that enabled the implementation tourism in APAJ as well as the laws and decrees governing the process of creation and management. Using the theory of circuits of urban economy of the Santos (2008) to analyze the territory used by tourism on the beaches of Redinha Nova, Santa Rita and Jenipabu, showing their dependent relationship with the territory used by the upper circuit on the Via Costeira and in the Ponta Negra beach and its influence on the APAJ urbanization process. Ending with the analysis of the influence of the materialization of tourism in the transformation of stocks ways of being-in-space and space-be of the Santa Rita and Jenipabu beaches in each geographical situation of APAJ among the first decades of the twentieth century to the 2014. Fieldwork was conducted between 2012 and 2014, performing actions of qualitative interviews with older residents of Santa Rita and Jenipabu beaches, interviews with structured questionnaire with merchants of APAJ and collecting GPS points trades, identifying and mapping the territory used by the lower circuit in APAJ beaches.

O trabalho analisa a eficácia das políticas ambientais na área marinha do Litoral Norte de São Paulo, com base no levantamento e análise da legislação vigente, do material bibliográfico e cartográfico existente, entrevistas e trabalhos de campo. O principal instrumento de ordenamento territorial compreendendo a área marinha é o Zoneamento Ecológico-Econômico regional instituído em 2004, atualmente em fase de revisão, sendo identificados diversos problemas quanto à sua aplicação. Uma importante iniciativa governamental foi a criação da Área de Proteção Ambiental Marinha do Litoral Norte em 2008, atualmente com o Conselho Gestor constituído e diversas ações em desenvolvimento. Os principais desafios para a gestão ambiental da área marinha são: a estruturação dos órgãos competentes para a melhoria do licenciamento, fiscalização e proteção ambiental; a resolução da questão fundiária e das atividades possíveis nas ilhas; o ordenamento e regulamentação da pesca, do turismo e demais atividades no setor marinho. Em face dos empreendimentos previstos para a região, com forte influência no setor marinho, como o Projeto de Exploração de Gás de Mexilhão, e o projeto de ampliação do Porto de São Sebastião, faz-se necessária uma gestão ambiental mais eficiente e integrada entre as instituições atuantes na área.

One of the most important natural resources for sustaining human life, water, has been losing the basic requirements of quality and quantity sufficient enough to attend the population due to water contamination'problems, often caused by human beings themselves. Because of this, the sources of this resource are often located in remote places of the natural environment to ensure the quality of the water. However, when urban expansion began to occupy these areas, which were once regarded as distant, environmental pollution problems began to occur due to occupation of the land without planning. Based on this occurrence, this study aims to propose environmental zoning for the Maxaranguape river watershed in order to protect its water resources. This is important because this river can serve as a source of supply for the metropolitan area of Natal, the capital of Rio Grande do Norte. In accordance to this proposition, the model of natural soil loss vulnerability (CREPANI et al., 2001), the model of aquifer pollution vulnerability (FOSTER et al., 2006), and the legal incompatibility map (CREPANI et al., 2001) were used to delimit the zones. All this was done with Geographic Information System (GIS) and also created a geographic database update of the basin. The results of the first model mentioned indicated that 63.67% of the basin was classified as moderately stable / vulnerable, 35.66% as moderately vulnerable, and 0.67% as vulnerable. The areas with high vulnerability degree correspond with sand dunes and river channels areas. The second model indicated that 2.84% of the basin has low vulnerability, 70.27%) has median vulnerability, and 26.76% and 0.13% has high vulnerability and extreme vulnerability, respectively. The areas with the highest vulnerability values also refer to part of the sand dunes and river channels besides other areas such as Pureza urban area. The legal incompatibility map indicated that the basin has 85.02 km2 of Permanent Protection Area (PPA) and 14.62% of this area has some incongruity of use. Based on these results it was possible to draw three main zones: Protection and Sustainable Use Zone (PSUZ), Protection and Environmental Restoration Zone (PERZ) and Environmental Control Zone, which are divided into A, B and C. The PSUZ refer to the coastal areas of the basin, where the sand dunes are located. These sites should be areas of environmental protection and of sustainable urban expansion. The ZPRA refer to river channels, which are in high need of rehabilitation. The third zone corresponds to the rest of the basin which should have, in general, the mapping of possible sources of contamination for further control on the use and occupation of the river
