O crescimento populacional aliado à migração tem aumentado a pressão sobre o uso do solo urbano perpetuando sucessivos problemas de assentamentos informais e saneamento ambiental nos grandes centros. Esta situação se agrava ainda mais em épocas de chuvas intensas devido à ocorrência de enchentes. Este projeto faz parte de um conjunto de ações integradas de cidadania e inclusão social na região hidrográfica da baixada de Jacarepaguá, especificamente envolvendo a Comunidade da Vila Cascatinha, em Vargem Grande, a fim de gerar subsídios para políticas públicas em áreas de assentamentos informais, integrado ao projeto HIDROCIDADES (CNPq/CTHIDRO/CTAGRO), que visa a conservação da água em meios urbanos e periurbanos associado à cidadania, inclusão social e melhoria da qualidade de vida nas grandes cidades. Este projeto utilizou uma tecnologia adaptada dos telhados verdes para edificação popular (telhado de fibrocimento), com o objetivo de verificar aspectos construtivos, possíveis espécies com potencial de geração de renda, custos, efeitos no retardo do escoamento superficial das águas pluviais e outros benefícios associados a questões climáticas locais e de conforto do ambiente interno. Os resultados gerados demonstraram, entre outros, o estabelecimento de metodologia para implantação dos telhados verdes em habitações populares, o valor dos custos e resultados preliminares de espécies com potencial para geração de renda. Ainda, a implantação dos telhados verdes demonstrou ser promissora no controle do escoamento superficial, na aplicação do sistema de irrigação. Na simulação das chuvas, observou-se uma retenção de até 56% do volume precipitado. Observou-se o retardo da ocorrência do pico de até 8 minutos no telhado vegetado em relação ao telhado testemunho (convencional telhas fibrocimento). Foi observada a eficiência tanto no comportamento térmico interno como também no externo, uma redução da amplitude térmica interna em dia característico de verão (35,9 C), sendo capaz de r eduzir a temperatura interna em cerca de 2,0 C nos períodos mais quentes do dia e cerca de 4,0 C no ambiente externo em comparação com o telhado-testemunha (sem plantio), com potencial de modificação do microclima local. / The population growth and migration has increased the pressure on land use and urban occupation, increasing the problems of informal occupation (urban settlements) and environmental sanitation in large cities. This is even worse when urban floods occur. This project is part of a set of citizenship and social inclusion integrated actions in Jacarepaguá low-land hydrographic region, involving the Community of Vila Cascatinha, Vargem Grande, Rio de Janeiro, Brazil, in order to propose new public policies for informal settlements. This study is part of HIDROCIDADES project (CNPq / CTHIDRO / CTAGRO), which focus on water conservation in the urban and peri-urban environment associated to citizenship, social inclusion and life quality improvements in large cities. This project applied an adapted technology for green roofs on social interest buildings (fiber-cement tiles), in order to verify constructive aspects, possible crops to with income raising potential, costs, the effects on surface flow control and other benefits, such as buildings thermal comfort improving, microclimate. Results, demonstrated, among others, the establishment of a methodology for implementing green roofs for social interest buildings, costs and preliminary crops. In addition, the establishment of the green roof showed effects on controlling surface runoff. During the application of the irrigation system for rainfall simulation it was observed up to 56% retention of the total precipitation. It was observed a delay up to 8 minutes to runoff peak when comparing to the flow over tiles roof. It was verified the external thermal behavior, reducing the internal temperature range of typical days in summer (35.9 C), being able to reduce internal temperature by 2.0 C durin g warmer periods of the day and about 4.0 C in the external environment, compared with the tiles roof, being efficient on the local microclimate modification.

[pt] A pesquisa trata da relação entre ser humano e natureza. O paradigma moderno a entende de forma a constituir seu dualismo básico fundante, havendo completa ruptura e dissociação entre ambos. Percorrem-se as crises advindas dessa cisão radical tanto do ponto de vista ecológico, quanto subjetivo. Após, uma análise sobre a emergência de um paradigma holístico e transdisciplinar é observada, e a partir desses novos horizontes epistemológicos surgem os aqui chamados saberes emergentes. Esta denominação se refere aos novos saberes ecológicos: Ecologia Profunda, Ecofeminismo e Ecologia Social. Tais saberes entendem que o homem e a natureza estão intrinsecamente conectados em uma teia de interligações, inaugurando uma nova visão de mundo mais acolhedora e baseada no cuidado. Para aprofundar o tema, há a proposta de análise das comunidades sustentáveis como materializadoras dos pressupostos dos novos saberes emergentes, incluindo a teorização de Donald Winnicott sobre a atualização do verdadeiro self. / [en] The research deals with the relationship between humans and nature. The modern paradigm to understand so as to constitute its founding basic dualism, with complete rupture and dissociation between them. Crises arising from this radical split both from an ecological point of view, and subjective to run. After an analysis of the emergence of a holistic and interdisciplinary paradigm is observed, and from these new epistemological horizons arise here called emerging knowledge. This name refers to the new ecological knowledge: Deep Ecology, ecofeminism and Social Ecology. This knowledge understand that man and nature are intrinsically connected in a web of interconnections, inaugurating a new vision of more welcoming world and based care. To deepen the theme, there is a proposal for analysis of sustainable communities as materializadoras the assumptions of the emerging new knowledge, including the theory of Donald Winnicott about updating the true self.

The aim of the study was to investigate the changing role of the secondary school principal in building sustainable communities. It is supposed that communities that are not sustainable affect secondary schools. The focus is on how the secondary school principal should go about building, sustaining and uplifting the school community. The direct and indirect involvement of secondary school principals in community issues, could contribute to sustainability within the community, which gradually becomes a reality. The task of the secondary school principal is realised through the results of effective educative teaching and learning practices. Through literature study it was found that the role of the secondary school principal in enhancing sustainable communities would contribute to the upliftment of communities. The qualitative approach was successful in obtaining information about how the changing role of the secondary school principal in building sustainable communities is viewed. Recommendations were made concerning research findings for stakeholders and officials to note. / Educational Studies / M.Ed(Education Management))
