The coast environments were the first areas the man occupied in Brazil and they present, nowadays, high urbanization indexes. So, it's very important to analyze the environmental quality of those areas. The geomorphologic aspects are valuable for that analysis because they constitute the physical substrate on which such ant anthropic activities are developed. The cartography of geomorphologic features is essential to supply subsidies for the handling of coastal areas. However, the question about what proceedings are adequate to the geomorphologic cartography of recent sedimentation coastal lands is still in discussion by many authors. This article aims to compare two different technical proposals for mapping São Paulo's south coast, a sector that shows a great depositional complexity. The features related to recent sedimentation sectors were mapped because it's considered that they are necessary to understand the morphodynamic and, at the same time, they demonstrate difficulties in geomorphologic cartography standardization. Through the analysis of the produced maps it's possible to notice that the two proposals have positive aspects, but both need adaptations to cartographically demonstrate the geomorphologic complexity of São Paulo's south coast.

Marine turtles are reptiles that occur on the Brazilian coast and can travel very large distances between feeding and nesting grounds. Five species found in Brazil are threatened. The consumption of turtle meat and eggs is an ancient habit in many coastal communities around the world. The main causes that threaten these species are the increase in fishing and the drastic changes in the environment. The presence of turtles near the beaches and their accidental capture were reported by fishermen in the region of Cananéia, where this work was developed. This study was also made based in interviews of fishermen that living in the area and the follow up of their fishing activities. This methodology made possible to identify the turtles in the area, the behavior of the fishermen with these animals and the relation between non-commercial fishing and turtles. The fishing traps area has a direct relation with the capture of turtles. The higher incidence of turtle capture is usually next to islands, rocky coasts, low lands and bay entrances, which are areas where the most common species of the region (Chelonia mydas) normally look for food. The fishermen opinions about the critical situation of these species and their conservation has also been studied. Several programs in Environmental Education for the communities of the region have been recommended

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.

Oil spills cause serious damage to the cost life and environments. Those impacts affect ecologic and socio-economic resources (like fishing and tourism). Within this background, response actions have two main objectives: the contaminant removal, with the less additional impacts, and enhance environment restoration in order to make this process complete in the shortest time possible. The present work proposes to contribute for the emergency environmental management in cases of oil spills by systematization of relevant information for oil spill environmental sensitivity maps. The next stage was to insert all these data on a geographic database, which allows data access by web. Beside that, this work aimed to recommend suitable clean-up techniques for the ecosystems located on the study area, composed by the municipalities: Praia Grande, Mongaguá, Itanhaém and Peruíbe, belonging to Baixada Santista and Iguape, Cananéia and Ilha Comprida, south cost of São Paulo state. This area is situated between two important Brazilian ports: Santos and Paranaguá, and that make it under considerable accident risks. The results were all data inserted on the geodatabase and available to user recover the information by web consulting. With that, this work wishes to contribute to individual emergencial planning of the region.
