Fatores de sucesso ou insucesso do turismo ambientalmente sustentável : percepção das autoridades públicas no pólo costa das dunas do Rio Grande do Norte

This study aims to compare the thermal performance of tiles made from recycled material (waste packaging cardboard with aluminized film) with the tiles of fiber and bitumen, fiber cement and red ceramic with the aim of verifying the suitability of tile to be used in hot and humid climate of low latitude. The samples were selected according to the availability from Natal RN market, as they are sold to the consumers. The methodology was based on studies that used experimental apparatus composed of thermal chambers heated by banks of incandescent bulbs, to analyze the thermal performance of materials. The tiles in the study were submitted to analysis of thermal performance, thermophysical properties and absorptance, using chambers of thermal performance, measuring the thermophysical properties and portable spectrometer, respectively. Comparative analysis of thermal performance between two samples of the recycled material with dimple sizes and different amounts of aluminum were made, in order to verify, if these characteristics had some interference on the thermal performance of them; the results showed no significant performance differences between the samples. The data obtained in chambers of thermal performance and confirmed by statistical analysis, showed, that the tile of recycled material have similar thermal performance to the tile of fiber cement. In addition to these tests was carried out the automatic monitoring of a building covered with tiles of recycled material, to verify its thermal performance in a real situation. The results showed that recycled shingles must be used with technical criteria similar to those used for fiber cement tiles, with regard to the heat gain into the building. Within these criteria should be taken into account local characteristics, especially in regions with hot and humid climate, and its use must be associated, according to the literature, to elements of thermal insulation and use of passive techniques such as vented attics, ceilings and right foot higher

Democratização do acesso a água no semi-árido: o caso da comunidade rural de Pendências dos Emídios no município de Serrinha/RN

Brazil lives a time of experimentation and maturity as it pertains to managing the use of water, which comes institutionalising increasingly social participation. In Rio Grande do Norte, since 1997, the government has been developing actions accordingly, through the State Department of Water Resources, which has implemented a programme of adutoras within the State and created Water Users Associations, in the installation of dessalinizadores for places where the Adutora was not necessary or not yet arrived, so that should be managed by communities through associations of users. Since 2003, Civil Society Organisations - CSOs come through ASA - Articulation in the Semi-arid Brazilian, implementing the P1MC - Program of Training and Mobilization for Social Living with the Semi-Arid (One Million Rural Cisternas), in its third year of implementation in Rio Grande do Norte, in the spirit of working together with the semi arid. In the municipality of Serrinha / RN which incorporates the Semi-arid region, we find in the rural community of Pendêcias dos Emídios the experience of the State and Civil Society, which referred to a discussion about the environmental sustainability of these initiatives. The general objective of this work is to examine the strategies for participatory management in the use and access to water in the community of Pendêcias dos Emídios of the municipality of Serrinha / RN, to understand how those experiences can contribute to environmental sustainability. The methodology used envolvel bibliographic research in categories involving each article, the analysis of the terms of reference of each strategy as part of the documentary research, the application forms covering 40 families benefited, and interviews based on comprehensive analysis of the speech. This study is divided into 02 articles, where the first is a discussion held on collective action and environmental sustainability, and the second is held a discussion about the sustainability of the initiatives underway to access water. The results of the discussion held on 02 articles that had their empirical built from the experience of the Commonwealth of Pendências dos Emídios revealed how far will the ability of the State to promote collective action and the limitations of the perception of sustainability that permeates these initiatives in the search for democratic access to water in semi-arid

O Circuito espacial de produção do biodiesel: configuração no território brasileiro e uso do território Norte-Rio-Grandense

This research aims to understand the use of the territory from the Rio Grande do Norte to the circuit spatial of production from the Biodiesel understanding it as part of the national context. The introduction of biodiesel into the Brazilian energy matrix begins to take shape in the year 2005 with the implementation of the National Program for Production and Use of Biodiesel (NPPB). This is anchored on three pillars: social inclusion (through family agriculture), environmental sustainability and economic viability. The NPPB consists of a set of standards, which turned into shares and distributed by almost all the national territory. Our reflection assumes that the places accommodating different forms of productive activities and, thus, the performance of the circuit space of biodiesel production depends on several factors, including the configuration of the territory they receive this new nexus economic. Understanding that the places by their technical content determine the realization of productive activities, it was found that the inclusion of this circuit space production in Rio Grande do Norte, reveals the reality expressed in the national territory, where some places are endowed with a privileged technical content and other extremely poor infrastructure. As our research could confirm the circuit space of biodiesel production that is expressed in the way plants are distributed within the country (mostly in South-Central), in more significant participation of small farmers in the South in the supply of raw material for the production of biodiesel and the main raw material used for the production of agrofuels (soybeans, whose production sector is highly consolidated and technified). Already the project materialization of NPPB regarding the settlements and communities of the Rio Grande do Norte State, we observed that the "event" or advent of realization encountered a technical means lacking in infrastructure that need to be molded to the needs of production, or is to cultivate castor beans or sunflower would be needed inputs and implements that farmers don´t have. Given the above, the research concludes that, as proposed previously, the use of the territory of Rio Grande do Norte to this circuit has summarized the performance of experiments, either with regard to the participation of family farmers as suppliers of raw materials, including the development of related research in the stage of production fuel oil by Petrobras. This finding came from research done from the concept of "spatial circuits of production," which allowed the verification of the circuit that steps outlined in Potiguar territory. Regarding the inclusion of family farmers in the productive circuit in RN, research reveals that, in the manner as has been done, it is doomed to failure. Furthermore, we dare say that this persistence in trying to put these family farmers, the way is being made, and the resulting successive failures, indicating that social inclusion advocated by NPPB not take place, and that this production circuit relies on the same logic circuit concentrated and exclusive space for ethanol production

Natureza morta...edifício com vida: uma arquitetura sustentável para o Serviço de Verificação de Óbitos

Sustainability in buildings, while reducing the impact on the environment, contributes to the promotion of social welfare, to increase the health and productivity of occupants. The search for a way of build that meets the aspirations and development of humanity without, however, represent degradation of the environment, has become the great challenge of contemporary architecture. It is considered that the incorporation of principles that provide a sustainable building with careful choices of design solutions contribute to a better economic and thermal performance of the building, as well as functional and psychological comfort to its users. Based on this general understanding, this paper presents an architecture project aimed to health care whose the solutions adopted follow carefully the relevant legislation and sets his sights on the theme of sustainability. The methodology began with studies on the themes of verification service of deaths, sustainability and those application in construction developed through research in academic studies and analysis of architectural projects, using them like reference for the solutions adopted. Within the project analysis was performed a visit to the verification service of deaths in the city of Palmas in Tocantins, subsidizing information that, plus the relevant legislation, led to functional programming and pre-dimensional of the building to be designed. The result of this programming environments were individual records with information from environmental restrictions, space required for the development of activities, desirable flow and sustainability strategies, that can be considered as the first product of relevance of the professional master's degree. Finally we have outlined the basic design architecture of a Verification Service of Death SVO/RN (in portuguese), whose process of projecting defined as a guiding line of work four points: the use of bioclimatic architecture as the main feature projectual, the use of resources would provide minimal harm to the environment, the use of modulation and structure to the building as a form of rationalization and finally the search for solutions that ensure environmental and psychological comfort to users. Importantly to highlight that, besides owning a rare theme in literature that refers to architectural projects, the whole project was drawn up with foundations in projective criteria that contribute to environmental sustainability, with emphasis on thermal performance, energy efficiency and reuse of rainwater

Influência do lodo de ETE na massa para fabricação de cerâmica vermelha

The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pollution resulting from inappropriate management of residues. Thus, is necessary achieve a new equilibrium between the grow from raw materials and energy and the residue generation. This equilibrium should be achieved by technical and economic feasibility of environmental supported models through recycling and reuse. The red ceramic industry stand out in residue absorption question as raw material due their clay mass heterogeneity, constituted by clay minerals and non-clay minerals with wide mineralogical variation, allowing residue inclusion which act like plastic or non-plastic materials, contributing to retain heavy metals contained in residues in the vitreous mass formed during the burning of the ceramic bodies. This work propose the study of the influence of incorporation of 25 wt.% sludge from wastewater treatment plant, according preliminary results, in the mass to produce ceramic bodies. The raw materials was characterized through chemical composition analyses by XRF, mineralogical analyses by XRD, thermal analyses by TG and DTA, Atterberg limits and thermodilatometry. Subsequently was composed the mass with 75 wt.% of clay and 25 wt.% of dried wastewater sludge from UFRN WWTP. Samples with 6,0 x 2,0 x 0,5 cm was produced with unidirectional compacting under pressure of 20MPa and burned in temperatures between 950 and 1,200ºC. After fired, the ceramic bodies have been submitted to physical and mechanical analyses through the measure of firing shrinkage, water absorption, density, apparent porosity and flexural strength; crystallographic analyses through XRD and microstructure analyses by SEM. The technological properties obtained was satisfactory to production of roof tiles with 25 wt.% at 1,200 ºC, but the production of others products at lower temperatures was not feasible

Cuidado ambiental em tempos de sustentabilidade: explorando dimensões da conduta sustentável com estudantes universitários

The pro-ecological commitment (CPE) constitutes an important topic within Person- Environment Studies, here seen as a predisposition to practices that result in environmental protection. Under the framework of sustainability, the concept of sustainable behavior emerges, covering, in addition to CPE, new psychological dimensions such as: the future time perspective (PTF) and the ecological worldviews (VEM). The current study intended to explore the concept of sustainable behavior of university students, by means of the association among some of its dimensions: CPE, PTF and VEM. For this purpose, 380 undergraduate students of biology, ecology, nursing, geography, and social service answered a form containing: socio-demographic questionnaire, a question on self-assessment of environmental care, the Scale of Ecocentric and Anthropocentric Environmentalisms, the Scale Consideration of Future Consequences, and the Scale Ecological Worldviews. Based on descriptive and correlational procedures, it was found that 78% of the participants practice or have practiced environmental care (caregivers) and the spread of information has been the practice more frequently reported, and the source of influence for such practices were the school, social networks, and the contact with nature It was also observed the association between practice of environmental care and ecocentric environmentalism, consideration of future consequences and egalitarian worldview (worldview of fragile nature). The lack of environmental care was associated with anthropocentric environmentalism, apathy, and individualistic worldview (worldview of passivity). As expected, and suggested by the literature, positive association were found between the sustainable behavior dimensions investigated in this study and the practice of environmental care

A ocupação urbana do entorno de zonasde proteção ambiental de natal, suas condições de sustentabilidade e a relação com a ocorrência de insetos vetores

This study started from the hypothesis of the existence of a relation between the type of the urban occupation concerning to the sustainability conditions at the proximity of Environment Protected Zones and the occurrence of vectors insects in Natal, Rio Grande do Norte, Brazil. This research, which used data available by the City Administration Health and Urbanization Secretaries (respectively SMS and SEMURB), in the time period of 2006 to 2008, aimed to characterize the study site in terms of urban occupation, relating it to social environmental aspects of land occupation and the occurrence of vectors insects. This study is presented in two papers, the first one linking the occurrence of vectors insects and sustainable development indicators and the second relating the incidence of reported cases of Dengue and Dengue Hemorrhagic Fever (DHF) and the occurrence of larvae infection indexes of Aedes aegypti, in Natal, Rio Grande do Norte State. In the first paper, was made a correlation between Dengue Fever vectors and Visceral and Tegumentar Leishmaniasis vectors and sustainable development indicators, selected from IDS Brasil- 2008. Through factorial analysis a Sustainability Index (SI) was acquired for each region, the northern region of the municipality obtained lower numbers than southern region, which, in its turn, presented better sustainability conditions. Linking this index to vector infestation parameters shows a high significant correlation between the SI and the Breteau Index of Aedes aegypti (p=0,028) as well as with SI and sand flies infestation index (p=0,01). Higher rates in vectors infestation in regions with a lower Sustainable Development Index demonstrates that this index can be used to determine the increasing of probability of Aedes and sand flies occurrence in urban environment. The second paper analyzed the occurrence of the main vector of Dengue and DHF, the Aedes aegypti mosquito, and the relation between larvae infection indexes of this insect and reported cases of the diseases. This study revealed unexpected relation where areas with higher Breteau s Indexes showed lower infection rates of Dengue Fever, although showing high incidence of DHF

Conservação dos invertebrados em área de proteção ambiental litorânea no nordeste do Brasil: contribuições da educação ambiental para a sustentabilidade

Today's society is in a real collapse of an environmental nature. The populations are lost due to a dream of development without thinking of the consequences that said development can bring to human populations. Thus, it is necessary that strategies be developed for the purpose of protecting the flora and fauna that is at risk from suffering the pressure to achieve this development. Thus important issues involving the need to conserve nature and the creation of protected areas as these strategies are increasingly being developed in research, whether in the biological and / or social. In this sense, the aim of this research through environmental perception social actors for the formation of significant elements for understanding the relationship between man and nature, and from there to provide actions for sensitization. As well as changing attitudes towards environmental issues, to thereby provide analysis based on Environmental Education in order to provide the production of environmental knowledge as a tool that provides value shift. This area of research was to study the Environmental Protection Area Jenipabu - APA Jenipabu, located in northeastern Brazil. Where, from the environmental perception of students from schools within and around this Nature Conservation Unit notes were made regarding the value and meaning given by students, and how this, the feeling of belonging to these groups. This dissertation is composed of two chapters, the first is titled Environmental perception and feeling of belonging in the area of environmental protection in coastal RN - Brazil, where it makes a diagnosis of how these groups understands and realizes the Unity of Nature Conservation. The second, which is titled Construction of environmental knowledge and conservation of invertebrates in the Environmental Protection Area in the northeast coast of Brazil, specifically developed in the school from within the APA Jenipabu, in order to promote a sense of belonging for those students who become multipliers, in order to realize the importance and necessity of having this unit for Nature Conservation. Looking to the degree of importance of environmental education as a tool to raise awareness on conservation of invertebrates and is all the fauna and flora exists, whether in a conservation of nature or not

Educação ambiental como estratégia para inserção da sustentabilidade na formação em odontologia

This thesis proposes environmental education as a strategy for the inclusion of sustainability in the academic education of higher level. The dentistry course has been the object of study, which is justified by the recognition of the need for reflection on environmental issues in the dental academia, initially based on professional experience of the author as a dental surgeon. The aim of this study is to investigate the scientific production of dentistry and its content related to environmental issues, in addition to expanding discussions and reflections on the need to insert environmental education as academic content. With the specific purpose of verifying the amount and analyze the content of scientific articles involving issues related to sustainability in dentistry, Chapter 01 presents research in leading journals portals available on the internet. Works were surveyed where sustainability and related issues were present and placed in a theoretical framework that analyzes the dental service inclusion in the dominant economic model. These procedures are intended to prove the hypothesis that the dental profession does not produce significant scientific content that relates the profession to the environment and sustainability. A literature review was conducted with the statement of dentistry changes from its origins to the front position to the dominant development model and exemplification of the deleterious effects of this model on the environment. In addition, there was a scientific research in journals portals available on the internet and investigated the amount and content of scientific articles involving issues related to sustainability in dentistry. Chapter 02 has the specific purpose of providing content to expand discussions and reflections on the need to insert environmental education in undergraduate courses in dentistry, such as insertion strategy into a new development model guided by sustainability. In this, students questionnaires were given the 8th dentistry course of the period the Federal University of Rio Grande do Norte (UFRN), to be understood environmental perception of learners and were obtained grants for proof of the thesis that environmental education applied dentistry has the potential to make people aware and willing to act practicing and propagating sustainability in their conduct. The overall results indicate little scientific production, as the research and work that relates to dentistry to sustainability and the issues related to the environment have not significantly been present in the syllabus of the undergraduate courses in dentistry, despite the interest shown by survey respondents When such issues are addressed. In this context, it is proposed fostering actions to environmental education, so that dental professionals are engaged in the construction of a new development model based on sustainability, as despite the environmental theme seems to be little explored in the academic and scientific world of dentistry, there interest from students and great potential multiplier for appropriate environmental behavior. After proving the hypothesis that the environment-related content are poorly explored in the academic and scientific world of dentistry, the main conclusions were recognizing the importance of environmental education as an interdisciplinary tool for environmental thematic approach in undergraduate courses dentistry, in addition to implementing this new pedagogical proposal in the professional practice of dentists, given their potential multiplier for environmental knowledge.

Sustentabilidade das empresas associadas à REDEPETRO-RN

The present study investigated the management of social, environmental and economic sustainability practices employed by 72 oil companies in Rio Grande do Norte state in Brazil associated to Joint Business Network for Enhancing the Competitive Ability of Suppliers of Goods and Services to the Gas and Oil Industry in Rio Grande do Norte (REDEPETRO-RN). Thus, our investigation aimed to determine the extent to which sustainability practices of companies associated to REDEPETRO-RN are developed through their own efforts or influenced by the Triple Helix interorganizational arrangement (governamental organizations, education and research institutions, and industries). The research instrument used was a questionnaire in order to map and characterize the sustainability practices. The research subjects were business owners and managers. The data collected supported the descriptive, correspondence and correlation analyzes. Were identified a greater emphasis of the companies surveyed in developing sustainability practices and greater economic influence of business organizations in the construction of sustainability status. It was concluded with confirmation of thesis of the REDEPETRO-RN arrangement exhibits the characteristics and functioning of a common Interorganizational Cooperative Arrangement, not those of a triple helix interorganizational arrangement, given that the influences exerted for the development of social, environmental and economical sustainability on the part of teaching and research institutions, and government and business organizations do not interact with one another sufficiently to create a virtuous circle of cooperation among the associated companies. By contrast, the Interorganizational Cooperative Arrangement plays an important role in strengthening the competitiveness of companies affiliated to REDEPETRO-RN, by combining different competencies in an attempt at supporting the adoption of sustainability practices, a role reinforced by the scope of PETROBRAS, which, due to its economic importance, has considerable weight in the managerial decisions of associated companies

Mobilidade urbana sustentável em projetos estruturantes: analise urbanística e ambiental do corredor de transporte da Avenida Bernardo Vieira Natal/RN

The search for a sustainable urban mobility, has recast the public policy of transport and movement for all, in order to contribute to the welfare economic, social and environmental. Within this context, has as its main objective review here in the city of Natal in the state of Rio Grande Norte, the deployment of the new road infrastructure of the transport corridor of Bernardo Vieira Avenue and checking at least with regard to urban areas and environmental chosen here, as will indicators to assess sustainable urban mobility, that the theory has been well constructed, but in practice little way to apply the proposed guidelines for sustainability. To achieve this result, is initially a literature review with the principal investigators of the matter, since the concepts of indicators of sustainable urban mobility. And a second time, participating in to the case study, using the methodology of environmental awareness, through analysis photographs, notes and testimony in the study area ace to reach conclusions

Análise de Sustentabilidade em Projetos de Instalações de Produção de Petróleo

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

O dumping ambiental no setor sucroalcooleiro à luz do princípio da livre concorrência

The goal of this study is to investigate about the existence or absence of environmental dumping in the production of fuel ethanol in Brazil, as well as identifying the reasons why the figure of ecological dumping is pernicious to the principles enumerated in constitutional economic order, in particular the principle of free competition. In the twenty-first century environmental issues gained momentum and importance in these terms, which was seen as a mere fallacy given the concern of governments of various countries, after all, environmental protection shows up as the only means of bringing about the maintenance of life at planet. Indeed, it is essential to halt the drastic effects of climate change, and think fast and efficient solutions. Undoubtedly, the contemporary requirements that resulted in the transition to a new economy brings with it the duty of enterprise search for sustainability, and this behavior can not be passive, otherwise it is imperative to work hard and incessant economic agents, even if initially costs are high, this step will ensure a production accountable, transparent and free from accusations of environmental degradation. It is also intended to study the importance of the sector not only as a source of economic growth, but mainly, its contribution to national development, without forgetting that this is devoted in the Constitution of 1988 as one of the objectives of the Federative Republic of Brazil. In fact, the criticism most common perceptions about the production of biofuels, said the interests of the countries producing them in large scale, will eventually generate a exhaustion of soil and a significant increase in food prices. However, the ethanol produced in Brazil is unique in that it is produced from cane sugar, a product is not intended for human or animal, not to mention that the recovery of land just to the rotation with the planting other cultures. It is expected that environmental certifications are useful to demonstrate the quality of ethanol for export and to refute unfounded criticism. Finally, this study will be analyzed further solutions for the plants to develop an economic activity without damaging the environment and in compliance with Brazilian law

A Produção mais Limpa como ferramenta em busca da sustentabilidade empresarial: um estudo de múltiplos casos em empresas do Estado do Rio Grande do Norte

This study aimed to assess the Cleaner Production CP as corporate sustainable tool, through the multiple case studies within companies from Rio Grande do Norte State. In order to achieve this goal a research methodology approach was set. The initial stage of the research methodology was based on a literature review on which it was observed that the CP can be linked with corporate sustainable once it prevents pollution and reduces the operational risks among employees, community and environment. In addition, CP can useful for companies position within competitive position as well as being applied to process, products and services. In order to observe these factors, CP was used within food industry (Company 1), textile industry (Company 2) and in a car dealer (Company 3). Regarding the results, Company 1 changed its raw material as well as implementing housekeeping (control use of water, energy and condensed milk). In Company 2, it was observed the three levels of CP. In other words, housekeeping (e.g. cutting process and manipulation of chemical products), changing technology (high pressure washing machine) and internal and external recycling. In addition, Company 3 considered only level 3 external recycling. As consequence, it was observed that can be applied either within industry as well as service sector. Unfortunately, it was not possible to observe any social gains on a monetary basis. This is due to limitations of the CP methodology and study complexity. Therefore, it was observed improvements regarding to social, environmental and economic areas. Nevertheless, it is necessary more commitment from top level management in order to consider CP like effective sustainable tool
