Considerando número expressivo de alunos matriculados nas diferentes etapas e modalidades de ensino no Brasil e o que estabelece a Constituição Federal de 1988, sobre a incumbência do Poder Público de promover a Educação Ambiental em todos os níveis de escolarização, pretendemos analisar, neste artigo, aspectos referentes aos marcos legais e às orientações pedagógicas da Educação Ambiental em nosso país. Tomamos como referência a perspectiva de alguns autores brasileiros que estudam o tema e analisamos as principais diretrizes legais da Educação Ambiental no Brasil e as recomendações dos Parâmetros Curriculares Nacionais referentes a Meio Ambiente. Diante dos sérios problemas ambientais que enfrentamos, acreditamos que a Educação Ambiental pode contribuir para transformações nos indivíduos e na sociedade. Defendemos, também, a importância da pesquisa em Educação Ambiental e consideramos que o conhecimento gerado pela pesquisa pode oferecer subsídios para ações que promovam mudanças capazes de garantir um planeta ambientalmente seguro e saudável.

The paper compares the evolution of the brasilian and chinese agriculture emphasizing the post II World War period. It tries to show the structural changes in the agriculture in both countries and characterizing the dynamics of them. For both countries, the effort of industrialization after 1945 meant to sacrify the agriculture to a second plan. In the 1970’ Brazil and China begin to modernize their agriculture and adjust it to new challangers put by the necessity of guarantee the food security. The paper concludes that, in spite of some present problems, both countries face adequately the defiance on their agriculture.

The objective of this paper is to evaluate the implications of the european environmental requirements for electronic equipment on brazilian electronic industry sector. These deter-minations deal with elimination of hazardous substances and management of electronic products waste and have reached not only the electronic sector companies in international level, but brazilian electronic sector as well. Most brazilian companies of the electronic sector are getting complied with the requirement that restricts the use of hazardous substances. The main consequences of this process are technological innovations and changes on contractual relationships among companies. Foreign companies branches are more advanced than local ones in terms of timing of compliance to the new requirements and technological perfor-mance, showing an alignment with headquarter strategies. Not being complied with these requirements avoid companies to achieve commercial benefits and open space for questions about policies Brazil must take.

This paper analyzes the dynamics of Brazilian cultural policy between 1995 and 2010. Studies related defend the existence of a "contrast" between the results obtained by the government of Fernando Henrique Cardoso (1995-2002) and Luiz Inácio Lula da Silva (2003- 2010), that divide it between a model "neo-liberal" and a "democratic" model of cultural policy. Our main achievement is to produce empirical knowledge that can verify these claims. The build of indicators was guided by the theoretical assumption of the historical new institutionalism, discussed by Pierson (2006), and the observed universe comprises the totality of cultural producers who have submitted projects to “Mecenato”, registered in SALICNET - Ministry of Culture.

In this paper, data on the fauna of Ephemeroptera and Trichoptera (ET) from a Cerrado stream was analysed in order to test the hypothesis that the high seasonality of this biome can influence the composition of ET between the wet and dry seasons. The community structure was evaluated using Detrended Correspondence Analysis and Cluster Analysis (Morisita Horn-UPGMA). Environmental factors were analyzed using the Principal Components Analysis. In order to test the effect of abiotic variables on the fauna, It was applied the Procrustean Randomization Test (Protest) and Mantel Test. The environmental factors recorded for this study had a significant effect on the ET fauna from Córrego do Pedregulho. Faunal similarity was high throughout the year, indicating that although there was density of fluctuation, due to rainfall variation, the faunal composition showed little temporal variability. On the other hand, it was possible to observe that the genus Lachlania (Ephemeroptera) occurred preferably during the rainy months and that the faunal composition during the dry season was less variable than those from other seasons. Therefore, environmental seasonality had a partial effect on the faunal composition of ET from Córrego do Pedregulho.

Species of colonial green algae from 10 Conservation Units from the Southern Brazil were surveyed. The samplings were carried out in 105 stream reaches, consisting of 10 m length transects. In addition to biological data, some environmental variables were measured: depth, current velocity, water temperature, turbidity, specific conductance, pH, dissolved oxygen and nutrients (total nitrogen and orthophosphate). Three species of colonial green algae [Bohlin Ecballocystis pulvinata var. pulvinata, Tetraspora gelatinosa (Vaucher) Desvaux and T. lubrica (Roth) C Agard] were recorded and these species were described and illustrated. Based on the environmental data, it was observed some patterns of ecological distribution, including the occurrence of E. pulvinata var. pulvinata in environments with higher water temperature and current velocity values, while Tetraspora species typically occurred in environments with lower total nitrogen, orthophosphate and specific conductance values.

The informal milk is recognized as the product marketed without inspection. We evaluated the microbiological quality, nutritional ingredients and substances inhibiting bacterial growth in 100 informal samples from cows milk, marketed in the southwest region of the state of Sao Paulo, Brazil. It was found that 77% of Somatic Cell Count (SCC) and 86% of Total Bacterial Count (TBC) of the samples were at odds with the maximum values required by Instruction Rules 62 of the Ministry of Agriculture and Livestock Supply. It was identified to solids contents in disagreement (36%), protein (23%), fat (38%), nonfat dry extract (43%) and 73% urea nitrogen. In 59% of the samples was detected residues of the bacterial growth inhibitors. Were isolated 240 strains of micro-organisms with a prevalence of enterobacteria, streptococci, staphylococci and fungi. The informal milk is marketed in the region without the minimum hygienic conditions and present risks to public health, and represents serious socio-economic problem for the region.

The management of solid waste originated from the treatment of domestic and industrial sewage in wastewater treatment plants is a current challenge in the Brazilian reality. However, the planning and the final destination of sludge end up being overlooked, causing serious damage to human health and the environment. The use of sewage sludge in the agriculture is growing in Brazil and is regulated by the Resolução CONAMA Nº 375/2006 which establishes the criteria and parameters so that the sludge can be disposed on the ground safely to the environment and the population. This study aims to define the effects of using sewage sludge in soil according to the results of the bibliographic survey of theoretical and practical studies using this waste in the recovery and conditioning of soil for agriculture and recuperation of degraded areas, and to define whether such type of sludge recycling is environmentally and socially feasible and safe. It can be said that the reuse of sewage sludge in soil meets the search requirements for an alternative that brings agronomic, environmental and economic benefits, as well as being an environmental and social healthy alternative if properly attended the laws that deal with the subject, anyway those should be reviewed and updated taking into account Brazilian soil and climate conditions, thus justifying need for more studies in the area

Os movimentos conservacionistas, desde a década de 80, impulsionam a predileção por produtos cujos fabricantes visam à sustentabilidade, ou seja, à degradação mínima do meio ambiente na produção e no consumo da sociedade atual, de modo a não comprometer os recursos naturais para as gerações futuras. Essa tendência fez países, a início os desenvolvidos, criarem regras, regulamentos ou normas de produção visando à preservação ambiental, a serem seguidas na produção por outros países com quem desejam estabelecer comércio. O que pode se configurar, principalmente para os países em desenvolvimento, uma barreira comercial - geralmente não tarifária - difícil de transpassar. O Brasil, como país em desenvolvimento e grande fornecedor de produtos primários para o exterior, enfrenta frequentemente essas barreiras comerciais com propósitos ambientais, muitas vezes de forma não planejada. Isso provoca, especialmente em pequenas e médias empresas, um aumento dos custos de produção e dificuldades de competir no mercado internacional. Este trabalho procura expor os principais produtos que sofrem notificações ambientais, mais especificamente dos Acordos SPS e TBT, e estabelecer uma relação entre essas notificações e a pauta exportadora brasileira durante o período de 1997 a 2014
