Comunidades tradicionais em áreas protegidas: convergências e lacunas da Política Urbana e Ambiental na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão/RN

This work presents a reflection on possibilities and boundaries of consolidation and expansion of human settlements characterized as traditional communities that are located within protected areas, using as study reference the State Sustainable Development Reserve Ponta do Tubarão, at Rio Grande do Norte state. The main topics highlight the conflict between the right to housing and the prevalence of fundamental rights of traditional populations, opposed to the diffuse right to environment, according to the regulatory framework of the Brazilian Urban and Environmental Policies. At the same time that these settlements, historically built, are substantiated by the principles of recognition of rights to traditional populations, they are in a condition of complexity to the resolution of conflicts in its urban dimension and lead to an impairment of natural sites. This work questions how the instruments of land use and occupation are defined and relate to environmental planning, especially considering that the settlements are located in Permanent Preservation Areas (APP). It aims to further the discussion of the urban dimension in settlements, characterizing its formation and growth process, to identify the gaps and convergences between the Urban and Environmental Policy, under the foundations of a socio-environmental approach. The results spotlights the conflicts between occupation and natural areas, inferring that the definition of Urban Policies instruments and its integration with Environmental Policies instruments account for essential and priority actions to the achievement to the rights to a sustainable city, as determined in the Cities Statute and environmental protection goals, defined for the Conservation Units

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

Programa ciclovida como política de mobilidade urbana sustentável: estudo empírico na Universidade Federal do Paraná

The urban mobility has in the bicycle its symbol of the most environmentally sustainable modal of transportation of the planet, title conferred by the United Nations Organization (ONU). Nevertheless, the cities suffer with the traffic jam caused by the automobile fleet growth, what implies in a larger displacement time, injuries to the environment, to financials and to the quality of life. In order to build in a sustainable way the urban mobility, public policies are necessary to encourage the preferential usage, by the society, of the mass transit or the non-motorized type of transportation. Objecting cooperate with the public power and the civil society, this study intents to, through an analysis about the UFPR Extension Program - CICLOVIDA, propose a sustainable urban mobility public policy development, with emphasis in the bicycle´s usage. eferentially, it is discussed concepts such as Society, State and Government as well as public policies, which go in cycles to the State´s and Government´s responsibilities; and are presented the Sustainable Urban Mobility Public Policies (PPMUS) in Brazil. Also, it is debated about the transport by bicycle as an option to the sustainable mobility. Methodologically, the study is of an empiric-social nature, with the application of both qualitative and observational methods, what characterizes as an exploratory level of research, with the researcher´s involvement in the participant form, due to her acting on the Program. Regarding the research lineation, it was used the bibliographic and documental form as well as case study, by means of the nonparametric sampling by accessibility or convenience. Related to the data collection technique, it was used structured interviews with self-applied questionnaires and natural participant observation. Aligned with the research´s objective and matter, the outcome confirmed that the Extension Program CICLOVIDA of the Federal University of Paraná (UFPR) may effectively contribute in the development of a PPMUS proposal with emphasis in the bicycle usage. Thus, it was built a political proposal with a free form writing, objecting subsidize policies both institutional as public MUS through the bicycle usage and therefore, support the mobility, also contributing to the sustainability and to the public development planning.

Efeito dos nutrientes (nitrogênio e fósforo) sobre o desenvolvimento da Gracilaria birdiae: crescimento e possível uso como biofiltro

Marine shrimp farming has grown exponentially during the last years in Brazil. In spite of the promising economical situation, this activity is facing an increasing criticism due to its environmental impact. Thus, the necessity of alternatives to mitigate environmental degradation caused by this activity. An alternative that is being studied is the policulture that is the integrated culture of two or more organisms, normally one of them a filtering organism. Among filtering organisms, macroalgae are very practicable because they are efficient in the removal of the exceeding nutrients of the water and do not leave residues in the water. Besides, the integrated culture with macroalgae allows the economical exploration of the seaweed (for the manufacture of jelly and jam, for the dairy industry, pharmaceuticals, etc.) along with possibility of a sustainable aquaculture. In the present experiment, the development of the seaweed Gracilaria birdiae, the influence and tolerance of this species to the environmental parameters, and its absorption efficiency in relation with the three kinds of macronutrients (NH4+, NO3- and PO4-3) found in the effluents of marine shrimp farming was studied. The experiment was divided in two parts: a laboratorial part and one part carried under natural conditions. The water used in the laboratory trial was collected in the shrimp ponds of Tecnarão farm and distributed in aquaria containing 20 g of G. birdiae. In the field trial, 0.5 kg of G. birdiae was inserted in PVC cages cultivated in the farm. The results of the study showed a modest growth of G. birdiae, probably due to its low tolerance to highly eutrophicated environments. However, the removal of nutrients was very expressive. Ammonia was reduced in approximately 34 %. Ortho-phosphate showed a reduction of 93.5 %. The capacity of biofiltration of the NO3- by the macro algae was of 100 %, showing that G. birdiae is a seaweed-filtered with a high level of removal for this nutrient under laboratorial conditions. In spite of the low growth of the macro algae in the experiment, the results in relation to the removal of nutrients of the water was encouraging, suggesting that this species can be an efficient biofilter and thus, a strong candidate to be used in a sustainable aquaculture

Desenvolvimento sustentável: algumas linhas de ação para a Amazônia

As sociedades enfrentam problemas cuja complexidade aumenta na razão direta do crescimento da população e dos impactos causados por uma demanda exponencial de recursos, energia, água e espaço físico na Terra. Embora seja desejável que cada cidadão contemporâneo participe ativamente na resolução dos problemas e na tomada de decisões coletivas, muitos se sentem incapazes de, ao menos, entender a magnitude das questões e correspondentes implicações em um mundo definitivamente imerso na ciência e na tecnologia. Assim, a concepção de tempo – especialmente a de tempo geológico – é crucial para fazer emergir a educação em ciência como instrumento capaz de permitir que todos, jovens e adultos, compreendam o mundo onde vivem. As taxas de derrubada de florestas tropicais na grande bacia hidrográfica amazônica aceleraram-se desde a metade do século XX, com alguns intervalos de redução. Os elementos revelam ser inadiável fortalecer e reintroduzir as Ciências da Terra na Educação, especialmente no Brasil. O conhecimento pode contribuir efetivamente para formar cidadãos conscientes e críticos, capazes de tomar decisões equilibradas e ponderadas sobre atividades humanas que envolvam ocupação e uso do ambiente, materiais naturais e fontes de energia. Neste artigo procuramos refletir sobre a importância do conhecimento geocientífico para formar cidadãos capazes de contribuir nos dias de hoje para plena adoção do conceito de desenvolvimento sustentável. Os dois elementos são fundamentais para que seja possível formular novas interseções e introduzir inovações no contexto da região Amazónica.

As espécies analisadas foram hierarquizadas com base na análise de valor potencial de exploração sustentável (VPES) dos PFNM, integrando-se às seguintes informações obtidas a partir de revisão bibliográfica: densidade, parte usada, capacidade de regeneração natural e crescimento, conhecimento sobre biologia reprodutiva e dinâmica populacional, processamento requerido e nível de injúria ou toxicidade. Os resultados obtidos evidenciam ser possível a conservação e desenvolvimento regional, a partir de alternativas sustentáveis de uso dos recursos florestais. Das 79 espécies observadas, 38 atingiram VPES igual ou superior a 10, sendo consideradas de elevado potencial de exploração sustentável de PFNM.

Proposta de uma matriz de decisão em energia hidrelétrica com o uso do método multicritério, para formulação de políticas públicas no estado do Paraná

Brazil is internationally acknowledged for its renewable sources, most notably, hydroelectric power plant projects which correspond to 65% of electricity production supply to the National Interconnected System. The main question behind this research is: what are the weights and the relative importance of the variables which have influence on the decision making process for the expansion of hydroelectric generation projects in Parana? The main objective is to propose a multi-criteria decision procedure, in association with water sources options that take into consideration the weight and relative importance of the alternatives having influence on the decision by enterprises in the generation of electricity in the state of Paraná. As far as the approach to the problem is concerned, this research can be classified as having mixed methodologies, applying Content Analysis, Delphi technique and the Analytic Hierarchy Process. Following Delphi methodology, a group of 21 was selected for data collection, all of those linked to Paranaense hydroelectricity market. And the main result was the construction of a decision tree in which it was possible to identify the importance and relative weight of the elements associated with the four dimensions of energy. In environmental dimension, the highest relative weight was placed on the loading capacity of Parana system; the economic dimension, the amortization of investment; in social dimension, the generation of direct work places and in institutional dimension, the availability of suitable sources of financing. Policy makers and business managers make their decisions based on specific criteria related to the organization segment, market information, economic and political behavior among other indicators that guide them in dealing with the typical tradeoffs of projects in hydropower area. The results obtained in the decision tree show that the economic bias is still the main factor in making investment decisions. However, environmental impacts on the State loading capacity, income generation, providing opportunities for direct as well as indirect jobs. And at an institutional level, the absence of funding sources show that the perception of experts is focused on other issues beyond the logic behind development per se. The order of priority of variables in this study indicates that in the current environment of uncertainty in the Brazilian economy as many variables must be analyzed and compared in order to optimize the scarce resources available to expand local development in relation to Paranaense water matrix.

A gestão da floresta e o planeamento do uso do solo

A temática desta dissertação é a gestão sustentável da actividade florestal. Tem como objectivo o desenvolvimento e aplicação de metodologias de planeamento e gestão do uso do solo. As preocupações com as intervenções na paisagem e com a incorporação das componentes que a constituem no planeamento e na gestão do território tem vindo a ter um maior desenvolvimento desde a década de 70. Por sua vez, as iniciativas políticas nacionais e internacionais na área do ambiente tiveram um maior impulso a partir dessa época, conduzindo a uma situação em que as preocupações com a sua conservação, gestão e qualificação assumem um papel fundamental. Um aumento da qualidade das paisagens implica um correcto planeamento do uso do solo e um subsequente esquema de incentivos à realidade sócioeconómica, potenciadores de um desenvolvimento sustentável. A gestão e o desenvolvimento sustentável pressupõem, por um lado, uma utilização parcimoniosa dos recursos, mas também uma articulação correcta dos usos às potencialidades do território, num quadro de planeamento e gestão do espaço que permita e promova o desenvolvimento de actividades económicas viáveis. Reconhecendo a forte influência que a acção antrópica tem exercido sobre a paisagem, privilegia-se a avaliação do factor evolução do uso do solo e a relação destas alterações com origem na actividade humana e com causas naturais de forma a determinar as causas específicas das alterações de uso. Nesta perspectiva efectua-se uma avaliação retrospectiva do impacto das diversas medidas de gestão com reflexo nas paisagens do Concelho de Arganil. A metodologia desenvolvida divide-se em cinco fases e tem como resultados os cenários de evolução do uso do solo e da demografia bem como a proposta de um modelo de ocupação sustentável. A escolha deste concelho como território de estudo para aplicação da investigação produzida prende-se com o facto de se considerar que ele é representativo de toda uma realidade da actividade florestal numa região vasta e de características razoavelmente idênticas, na qual existiram mudanças acentuadas de uso do solo e do meio sócio-económico nos últimos 50 anos, e de apresentar tendências evolutivas semelhantes às dos outros concelhos envolventes, o que permitirá aplicar a metodologia desenvolvida a outras áreas.

Adequabilidade do uso das terras agrícolas no município de Araras, SP.

Os estudos de adequação do uso agrícola das terras permitem identificar áreas com alto risco de degradação por apresentarem uso mais intensivo que a potencialidade de suas terras, assim como podem indicar áreas com uso adequado ou mesmo aquelas em que o uso está abaixo do potencial produtivo de suas terras. O presente trabalho objetiva avaliar se as terras agrícolas no município de Araras, SP estão sendo subutilizadas, sobreutilizadas ou encontram-se com uso adequado, através da interseção digital dos mapas de aptidão agrícola e de uso e cobertura das terras da área estudada. O estudo pode se constituir em uma importante ferramenta para o planejamento e desenvolvimento rural, de forma sustentável. Para a elaboração do mapa de adequabilidade das terras usou-se o mapa de aptidão agrícola Oliveira & Berg [1] e o mapeamento do uso e cobertura das terras Valladares & Tôsto[2]. Conclui-se que dado a uma boa aptidão agrícola, as terras do município apresentam-se na sua maioria com uso adequado.

Avaliação da capacidade de uso das terras da quadrícula de Araras, SP.

O uso da terra, sem o prévio conhecimento do potencial produtivo do solo, pode desencadear os indesejáveis processos erosivos e a consequente degradação ambiental, com perda da capacidade produtiva do sistema (arraste de solo e fertilizantes), assoreamento, eutrofização de rios e mananciais, principalmente. Este trabalho teve como objetivo avaliar a capacidade de uso das terras do município de Araras, SP, que pode se constituir numa importante ferramenta de planejamento e desenvolvimento rural, de forma sustentável. Como metodologia, adotou o sistema de classificação de terras, conforme Lepsch [1]. Os resultados indicaram que o município possui excelente potencial produtivo, pois 91,4% de suas terras são apropriadas para culturas anuais, perenes, pastagens, reflorestamento e vida silvestre. Concluiu-se que a classe II foi a de maior significância, tanto pelo seu elevado potencial e opções de uso agrícola, quanto pela sua extensão territorial (79,4% da área municipal).
