This monograph aims to contribute to the understanding and analysis of extreme events and its correlation with anthropogenic actions, in order to understand the levels of human interference in the environment and to identify potential social and environmental damage that such events may result in Ubatuba, located on the northern coast of São Paulo state. Therefore, two strategies were established, on one hand, episodic analysis of extreme weather events, and on the other, the analysis of the impact of atmospheric phenomena in everyday society. In this case we gave greater emphasis to analysis years that had higher total rainfall. In this sense, the research was based on the standard deviation technique and percentages, which supported to characterize the exceptional rainy years, in addition, use of rhythm analysis technique that has helped to identify the active atmospheric systems. From a qualitative point of view, field works were carried out in order to make use of news by the local press and civil defense for years considered extreme (positive standard deviation). From this, it was analyzed how the extreme episodes of rainfall trigger repercussions in geographic space. Also the spatial distribution of rainfall were carried out by means of quantitative analysis of six rain gauges. It was found that the highest occurrences of impacts, are located in the central areas of the city, as well as the highest rainfall totals. In fact, Ubatuba/SP suffers from very high rainfall totals and has a singularity on the climate...

The city of Ilha Comprida, located on the Environmental Protection Area Cananéia-Iguape-Peruíbe (APA CIP) and Lagoon Estuary Complex of Iguape-Cananéia-Paranaguá, is located at the southern end of the coast of the state of São Paulo. Ilha Comprida is a progradational barrier consists predominantly of sandy sediments of the Quaternary Period. Bibliographic and cartographic surveys demonstrate a large amount of sediments in the last centuries, leading to the expansion of the island in hundreds of meters towards SW / NE. The island has been suffering intense morphological change in the northeast corner - NE, growing 35 meters per year. The objective of this study is to measure and analyze the floristic diversity found in its extreme NE, recent accumulation area of sediment, comparing the results with data obtained in equivalent segment, located on the edge SW, agradation preterit area. Given this reality, we chose to assess how the process of ecological succession respond to these dynamics. That is, if we think of ecological succession, NE end (latest) is assumed to possess plant species in the initial stage of succession as well as the SW portion. However, it is assumed certain differentiation between species in both areas, and less diversity in the first case (NE). Using the method of fixed installments adopted for similar quadrants, we attempted to measure and analyze the floristic diversity of the NE end and compare the data obtained in the field with those listed for the SW end. The results confirmed the hypothesis of the research, and prompted several questions that point to the need for further deepening research on this theme
