No Brasil pesquisadores vêm intensificando suas pesquisas na área da administração e administração pública, procurando rever os modelos antigos (patrimonialista, gerencialista e burocrático), evidenciando uma nova tendência de gestão participativa e a relação destes modelos com o grau de satisfação que os usuários de serviços públicos atribuem ao Estado. Conhecer esse grau de satisfação é um fator relevante na elaboração e implementação das políticas públicas. Neste contexto, este trabalho tem por objetivo avaliar o grau de satisfação do usuário de alguns serviços públicos na região do Grande ABCD. O universo da pesquisa limitase aos moradores dos municípios de Santo André, São Bernardo do Campo, São Caetano e Diadema. A pesquisa, de caráter descritivo, utilizou ferramentas estatísticas para comparar o grau de satisfação entre os municípios estudados. Para a coleta de dados foi aplicado um questionário adaptado de um instrumento de pesquisa utilizado pelo Governo Federal e composto por questões que foram desenvolvidas e agrupadas em quatro dimensões: Transporte, Saúde, Educação e Segurança Pública. Trabalhando com as médias foi possível observar que o município de São Caetano do Sul apresenta algumas diferenças (escores superiores no grau de satisfação) em relação aos demais municípios pesquisados, e também, que alguns desses municípios demonstram, em média, resultados próximos em algumas dimensões.

Tailings dams are structures that aims to retain the solid waste and water from mining processes. Its analysis and planning begins with searching of location for deployment, step on which to bind all kinds of variables that directly or indirectly influence the work, such as geological, hydrological, tectonic, topographic, geotechnical, environmental, social characteristics, evaluation security risks, among others. Thus, this paper aims to present a study on the most appropriate and secure type of busbar to design a layout structure of iron ore tailings, taking into account all the above mentioned variables. The case study involves the assessment of sites for location of dams of tailings disposal beneficiation of iron mine to be built in Bonito, in the municipality of Jucurutu in Seridó Potiguar. For site selection among alternatives, various aspects of the current state of the art were considered, one that causes the least environmental impact, low cost investment, adding value to the product and especially the safety of the implanted structure mitigates the concern about induced earthquakes as a result of liquefaction wastes somatized by dams in the region, as the tilling of Mina Bonito is located practically in the hydraulic basin dam Armando Ribeiro in environmental protection (APA). The methodology compares induced by dams in the semiarid region with the characteristics of the waste disposal and sterile seismicity, taking into account the enhancement of liquefaction by the action of seismicity in the Mina Bonito region. With the fulcrum in the methodology, we indicated the best busbar type for disposal of tailings from iron ore or combination of them, to be designed and built in semiarid particularly for Mina Bonito. Also presents a number of possible uses for the tailings and in engineering activities, which may cause processing to the common good.

The Amazon savannas occur as isolated patches throughout extensive areas of forest in the states of Amapá, Amazonas, Pará, and Roraima. There is a considerable variation in the composition of anuran assemblages in the localities and phytophysiognomies of Amazon savannas and given the absence of studies on reproductive behavior, a systematic and geographically wide sampling has been carried out in the Amapá savanna, located in the Eastern Amazon. The study was conducted in a savanna area in the state of Amapá to examine the composition, ecology, and reproductive behavior of anuran amphibians. We carried out 24 field trips in each phytophysiognomy (gramineous-woody savana, gramineous-herbaceous-woody savana, park savana, and arboreal savanna); for analysis of reproductive behavior observations were made during the period January to December 2013, lasting four consecutive days. Samples were collected by active and acoustic search along 20 plots of 100x50 meters. Twenty-one anuran species were recorded, of which four are new records for the state of Amapá: Dendropsophus walfordi, Scinax fuscomarginatus, Pseudopaludicola boliviana e Elachistocleis helianneae. The KruskalWallis ANOVA revealed significant differences between richness and species diversity in the phytophysiognomies (p < 0.05). The Bray-Curtis similarity coefficient divided the phytophysiognomies into three groups: arboreal savana, gramineous-woody savanna and gramineous-herbaceous-woody savanna, and park savanna. According to the non-metric multidimensional scaling, the structure of the anuran community resulted in a separation into three phytophysiognomies, with significant differences in the structure of communities (ANOSIM, R = 0.823; p < 0.001). In the study of community ecology, the results obtained for spatial, temporal, and trophic niche breadth suggest that the assemblage of anurans of the Amapá savanna is not composed of predominantly generalist species. Also, the presence of other specialist anurans may explain the processes of speciation associated with the isolation of habitats, resulting in heterogeneity and spatial discontinuity in the phytophysiognomies with open formations. The null model analysis revealed that the community is structured based on temporal and trophic niche, indicating a significant influence of contemporary ecological factors on the assemblage. The absence of structure based on spatial niche might be explained by the spatial segregation in the distribution and occupation of anurans in the different phytophysiognomies of the Amapá savanna. Regarding the reproductive behavior of anurans, 11 species were classified as having a long breeding season, intrinsically associated with the rainy season and the reproductive mode of most species that lay egg clutches in lentic water bodies. Six reproductive modes were recorded and parental care was observed in Leptodactylus macrosternum and L. podicipinus, whose reproductive mode is characterized by foam nests. Regarding behavioral reproductive strategies, calling males were observed in all species of anurans, satellite males were recorded only for D. walfordi, Hypsiboas multifasciatus, S. nebulosus and S. fuscomarginatus; active search for females was observed for Phyllomedusa hypochondrialis and L. fuscus, and male displacement was recorded only for Rhinella major and R. margaritifera. Of the reproductive behaviors observed, throat and vocal sac display is associated with courtship and territorial behavior exhibited by males. In addition to courtship behavior, visual signals associated with courtship strategies were recorded for the anurans of the Amapá savanna.

Residential homegardens have environmental and social roles in the urban environment. These green spaces can potentially minimize the impacts caused by the growth of cities, being an alternative to connect fragmented areas or offer refuge to wildlife and therefore support the conservation of biodiversity. In addition, the homegardens demonstrate a leading role in increasing human well-being by promoting socialization opportunities, contact with nature, local culture as well as improvements in food security for the urban families. Nevertheless, it is still unclear what specific characteristics of homegardens can act effectively in the conservation of the biodiversity, as well as in the construction of food security and well being of the homegardeners and their families. The first chapter of this thesis analyzed the diversity of plant species (native and exotic) and assessed the contribution of different types of urban gardens (ornamental and forest gardens alike) in the presence of wildlife such as birds, monkeys and lizards. In the second chapter we evaluated the contribution of those gardens to the welfare and food security of their owners. In order to do this, 41 gardens were visited in Pium, a southern coastal town in the northeastern Brazil, which also happens to be in a periurban region undergoing rapid urban expansion and pressure from the real estate market. We surveyed the planned biodiversity and fauna associated with homegardens. The data related to food security and welfare were sampled through interviews with the person in charge of taking care of the gardens. These interviews covered issues on the supply of food from the garden and absence of chemical products, as well as aspects of the GNH indicator (Gross National Happiness). The results showed that these homegardens generally contribute little to the maintenance of native plant species (native species = 29/ total = 187). From its main features, the gardens were classified as ornamental, forest gardens and forest farms. These groups had a different effect on the presence of the animals studied and the last two contained most of the sampled native species. The diversity of plants and trees was a good predictor of the presence of birds and monkeys. Thus, the contribution of yards for the conservation of biodiversity depends on the type of garden: some even can have negative effects on conservation. These results can direct new approaches to detailed understanding of gardens and also of public policies applied to urban planning. The results of the second chapter showed that the two types of forest gardens contributed to household food security, for providing food and medicinal herbs, which mostly did not have pesticides and chemical 12 fertilizers. But the three groups of gardens are important components for the well being of their stakeholders. Gardens help promote the transmission of knowledge on agriculture, socialization, contact with nature and bring up feelings related to peace and harmony. Thus, forest gardens can be considered important means to get through public projects and policies designed to encourage biodiversity and promote food security and well-being in urban areas

O mercado consumidor exige produtos agrícolas com altos padrões de qualidade e segurança e, segundo Gutierrez (2005), essa tendência se deve tanto à apreciação positiva por parte do consumidor a aspectos relacionados à aparência e às características sensoriais, como da garantia de segurança e qualidade. Para que esses padrões de qualidade sejam alcançados, torna-se cada vez mais importante a qualificação do produtor, mantendo-o inserido no mercado e viabilizando um novo padrão de produção agrícola que beneficie tanto os produtores, que podem ter acesso ao melhor nível de renda e de condições de trabalho, como os consumidores, que podem ingerir produtos mais saudáveis, mais seguros e com menor impacto ambiental na sua produção. A cultura do morango necessita de alto uso de insumos, irrigação, plásticos de cobertura de solo, dentre outros materiais. Hoje já se constata a resistência de alguns nichos de mercado quanto à segurança do morango devido ao grande uso de agrotóxicos, principalmente fungicidas durante o cultivo (SILVA, 2006). O uso intensivo de agrotóxicos além de resultar num custo de produção mais elevado, pode comprometer a qualidade do morango e gerar rejeição nos consumidores, estigmatizando o produto. A produção integrada auxilia a cadeia produtiva dessa cultura, pois objetiva a proteção dos recursos naturais, a minimização no uso de agrotóxicos, o atendimento aos requisitos sociais, a proteção da saúde humana (produtores, colaboradores e consumidores), a garantia da qualidade e da segurança dos alimentos (ANDRIGUETO; KOSOSKI, 2005). Instrumentos de extrema importância para o desenvolvimento sustentável e para apoiar os produtores rurais no processo de conversão para a produção integrada são os métodos de avaliação de impactos ambientais simplificados e participativos (CALEGARIO et al., 2008). Além disso, ferramentas auxiliares como as geotecnologias vêm sendo cada vez mais utilizadas de forma a apoiar as avaliações e a organização da propriedade rural seguindo conceitos de Planejamento Ambiental (BUSCHINELLI, 2006). O objetivo deste estudo foi aplicar um método de avaliação da gestão ambiental de estabelecimento rural dedicado à Produção Integrada de Morango (PIMo); incluindo, nesta avaliação, ferramentas da geotecnologia para auxiliar o planejamento ambiental das atividades produtivas, visando o desenvolvimento local sustentável.

A soja tem contribuição importante no cenário brasileiro. Sua expansão para fronteira amazônica tem chamado atenção, incluindo o Estado do Pará, particularmente pelos fatores de custo de produção, devido à carência de infraestrutura e mercado de insumos. Neste contexto a análise econômica e de risco dos polos produtores de soja no Pará é importante para elaboração de medidas adequadas para sustentabilidade econômica do investimento. A avaliação econômicofinanceira dos sistemas ocorreu com base na Análise de Custo-Benefício (ACB), utilizando como indicador a Receita Líquida obtida. Foi realizada, uma análise de eficiência que considera o fator risco, tendo sido utilizado o método de simulação monte-carlo, por meio do software @-RISK. De acordo com as estatísticas da receita líquida, o sistema produtivo de soja se mostra com muita variabilidade, de acordo com o desvio padrão, máxima e mínima. De acordo com a porcentagem de risco a soja apresentou nível médio a elevado de risco.

A discussão da Segurança Alimentar e Nutricional está envolta às políticas públicas que apresentam como objetivo a busca pela inclusão social. Assim, o artigo visa trilhar um percurso investigativo sobre a eficácia das políticas públicas voltadas para articulação de redes de segurança alimentar existentes no município brasileiro de Baturité, tendo como foco elevar as condições de renda e de emprego na agricultura familiar à exemplo do estabelecimento e incentivo à arranjos territoriais vinculados à agricultores familiares que desenvolvem sua pequena produção sobre uma base agroecológica na Região Maciço de Baturité no Estado do Ceará, os quais fornecem alimentos perecíveis para a alimentação escolar em creches e cozinhas de hospitais. Essas políticas configuram-se como eixo articulador e sistêmico, por meio do qual se desenham intervenções sociais focadas na participação, na relação poder público e sociedade civil, na partilha de poder e em mais uma série de outras vertentes, por possuírem concretude analítica. Os percursos em curso pautados na segurança alimentar e nutricional têm contribuído para a constituição de uma nova organização do espaço, bem como para inclusão social, gerando possibilidades de emprego e renda, além da melhoria da qualidade alimentar de diversos atores sociais envolvidos.
