O geógrafo Lutiane Queiroz de Almeida analisa neste livro os riscos e vulnerabilidades socioambientais para tentar compreender as inter-relações entre vulnerabilidades sociais e exposição aos riscos naturais, como as inundações urbanas. Como estudo de caso, analisa a bacia do rio Maranguapinho, na Região Metropolitana de Fortaleza, que além de ocupar territórios da capital cearense, se estende pelos municípios de Caucaia, Maracanaú e Maranguape. Recorrendo ao cruzamento de uma multiplicidade de dados, parte levantada por ele próprio, referentes a pluviometria, topografia, evolução de ocupação urbana, demografia, renda e educação, entre outros, Almeida criou e aplicou ao espaço analisado um Índice de Vulnerabilidade Socioambiental. Sustentado por inúmeros mapas e tabelas, o trabalho, que serve de modelo para o estudo de outras áreas urbanas do país, demonstra que os espaços com maior exposição aos riscos de inundação são aqueles que detêm os mais altos indicadores de vulnerabilidade social.

There is a huge debate surrounding the sustainability issues, especially urban sustainability. This article seeks to establish a critique of models of sustainable cities and postmodern city structured by dispersed city model produced by the logic of capital, it is an effort to confront methodological theoretical models of two cities, the capitalist model of production space and model sustainable city, the dispersed city model against a model of the compact city. For example it was used as environmental certifications for building a label denoting sustainable building when actually articulate a series of symbols that mask and reaffirm their production processes from the perspective of capital cities

Physiological responses like the thermal requirements for germination may be influenced during seed formation by environmental conditions such as water availability and temperature. Here we analyzed germination of embryos of Ingavera subsp. affinis from different sources in response to various temperature regimes, including calculation of degree days and accumulated rainfall during development and maturation. Embryos were taken from ripe fruits collected on trees located in São Paulo and Minas Gerais, and were analyzed as to germination, water content and dry matter content. The results showed that the origin of the embryos was related to variation in response under sub-optimal temperatures. Depending on the origin, I.vera subsp. affinis embryos were able to germinate even at low temperatures (10 to 15 ºC), with better performance attained from 20 to 25 ºC. This variation may be associated, among other factors, to environmental conditions during maturation and to the maturation stage at seed dispersal.

This investigation addresses the possibility of teaching themes related to environmental issues in Physical Education. We identified and classified such issues as: administrative and economic, aesthetic and philosophical, virtual, historical and geographical, sociological and political, physical and natural. Then, we discussed how the specific dynamics of culture, movement, and environment raises certain questions about each theme's relevance and its repercussions on teachers' professionalism. We believe that in the context of the daily intervention there are perspectives for both adaptation and transformation that might be further developed during classes in collaboration with the students.

The process of environmental impact assessment (EIA), in the extent of previous environmental studies, has as one of its functions to provide subsidies to the actions of environmental managment of enterprises. However, the proper estructuring of programs that allows to support this managment does not often occurs. This research sought as one of its objectives to evaluate in which extent the process of EIA can be a subsidie for the EMS, providing basic elements of this system. In addition, more specifically, the research had as one of its objetives the development of subsidies for the implantation of an Environmental Managment System (EMS), based on the model of ISO 14001 (2004), for a sewage treatment plant yet to be constructed in the city of President Venceslau / SP. In order to achieve theses objetives, a discussion was held based on the evaluation of environmental studies available in the library of Cetesb / SMA. Still, for the elaboration of subsidies for the EMS of the treatment plant, the research was focused on the structuring of environmental management program, based on the information contained in its Preliminary Environmental Report (PER). The research had as one of its products, the development of subsidies for the planning and control of the environmental aspects and impacts and for the environmental program of the enterprise, based on the use of environmental indicators. It was concluded, based on the results that, in general, the previous environmental studies analyzed showed little emphasis on the phase of development of structured environmental programs that offer guidelines to achieve the desired results for the environmental performance of the company.
