The setting up of wind power enterprises at Permanent Preservation Areas reflects the obvious conflict and necessary convergence between free market and energy security on the one hand, and the promotion of environmental quality on the other. From the perspective of energy sustainability, and in order to achieve development (in its complex meaning, which converges economic, social, environmental and cultural aspects), the harmonization between free market and an ecologically sustainable environment is required. This work aims to identify the link between the protection system of the Permanent Preservation Areas and the current constitutional order, by analyzing the implementation of wind power enterprises in these protected zones focusing on the proportionality aspects. A legal and purposeful research was developed, from a theoretical method, followed by collecting and analyzing both primary and secondary data. From these data, the law, the legal literature and judicial decisions were cross-examined, under the light of the Constitution and guided by the theory of proportionality and related development imperatives. In this context, the present study identified the link between the principles of the economic order, environment and energy law, finding their basis under the Federal Constitution and development. By reproducing this interrelationship and by means of post-crisis institutional reforms, the guiding objectives of the Brazilian electric sector began to corroborate the precepts of development, although issues regarding its sustainability still persist. The appraisal of proportionality indicates that the Permanent Preservation Areas protection system is insufficient to materialize the right to a healthy quality of life upon the implementation of wind projects at Permanent Preservation Areas, albeit seeking the harmonization between free market and environmental protection.

The main consequence of eutrophication is an increase in algal biomass, mainly cyanobacterial blooms. The high evaporation and low precipitation, characteristics of semiarid regions, contribute to the nutrients availability increase in drought periods and consequent aggravation of eutrophic condition in reservoirs. Climate changes tend to intensify eutrophication symptoms, mostly in a semiarid region. Therefore, the aim of this study was to evaluate the impact of an extended drought in algal biomass in Parelhas’s Boqueirão, a mesotrophic reservoir located in a semiarid tropical region. The low volume was associated to water quality degradation and to the high nutrients concentrations and low water transparency. The increase in nutrients availability in the water column, consequence of reduced precipitation and low reservoir’s volume, provided the necessary resources for algal growth and allowed a change in trophic state in Boqueirão reservoir. This study showed how an extended drought decreases water quality. The effect of drought in Boqueirão was late detected due to the reservoir´s low initial nutrients concentration. The reservoir´s volume reduction increased the nutrient availability along with the algal biomass increase and the reservoir´s trophic state change of mesotrophic to eutrophic.

The Green Economy offers real possibilities for productive innovation, economic growth and employment creation in Spain. These three factors are critical to facilitate the necessary change in the productive model to overcome the crisis. However, the measures taken by the current Conservative government have moved in the opposite direction: significant cutting in incentives for renewable, increasing tax burden on renewable energy production to self-consumption and privatizing public spaces of social and environmental interest. This hinders the achievement of the environmental objectives of the Europe 2020 strategy. A strategy that is born already in itself highly limited, unambitious and subordinated to the interests of energy oligopolies and the imperatives of the Stability and Growth Pact (Maastricht) and the Austerity policies imposed from EU institutions to overcome the 2008 financial crisis. So the Ecological Transition goes further, claiming a substantially change in Economic Policy away form the increasing commodification proposed by the Green Economy. Despite these limitations, young and unemployed people have much to gain from a comprehensive development of environmental industries. Therefore, innovative-sustainable plans, investment and training in green sectors are necessary to make easier the transition from a services low-valued economy to an innovative and sustainable model to make our country an environmental reference in Europe.

En este artículo presentamos un balance de la Antropología de la Conservación en el Estado español. Durante las últimas décadas, la protección de los espacios naturales ha aumentado de una manera exponencial en todo el mundo. A la vez que se extendía esta patrimonialización de la naturaleza, los trabajos etnográficos sobre las áreas protegidas han ido ganando terreno dentro de la disciplina y, en particular, en el campo de la Antropología Ambiental. La mencionada bibliografía ha puesto de relieve los múltiples aspectos derivados de las nuevas políticas territoriales de regulación, apropiación y mercantilización de la ‘naturaleza’. En este trabajo realizamos una revisión exhaustiva de la producción generada a raíz de este interés por las áreas protegidas en nuestro país subrayando sus principales aportaciones, características y debilidades. De este modo pretendemos reflexionar acerca de su continuidad, con el fin de evitar la mera reiteración y favorecer el avance en sus resultados.

In recent years the concept of "Land Stewardship" has gained a great importance. In short, it means that local entities and individuals can protect enclave of high ecological and cultural value. This vision has been effective in some places in the world with success. For example, the “Projeto Sempre Viva”, created in the town of Mucugê, a place located in one of Brazil´s most renowned Natural Protected Areas: the Chapada Diamantina (State of Bahia). We had looked over the available information about this project on the Internet, as well as a personal visit that was made to the site to know it and to have the possibility to talk to their managers. On this basis, it has been reached to the conclusion that this project, born to protect a Sempre Viva´s endemic species in danger of extinction, has turned into an important site for tourism and environmental education, completed with the preservation of the cultural identity of this region which is linked to diamond mining.

The Autonomous Region of Castilla-La Mancha develops from the approval of the Spanish Constitution a whole executive and legislative branch to implement its policies on environmental protection. The new legislation (Law 9/1999, of 26 May) has pursued the conservation and the integral protection of the natural elements of the territory demanding to new criteria as such the environmental quality of ecosystems or the exceptional landscape. The spread and the declaration of new natural spaces have caused a double geographical and territorial model. First, natural spaces located in rural mountainous areas with depopulation and aging problems. And second, natural spaces situated in areas densely populated

Ser resiliente implica ser capaz de adaptar positivamente a contextos de grande adversidade. Esta capacidade depende de múltiplos fatores (individuais, relacionais e contextuais) cuja mobilização se encontra dificultada entre os adolescentes cujo desenvolvimento ficou comprometido pela experiência de maus-tratos. Quando protegidos pelo acolhimento institucional, é nos pares, nos professores e nos funcionários da instituição que estes adolescentes encontram o cuidado, o suporte e o encorajamento de que necessitam, e que tanto pesa sobre o seu bem-estar. Foi, assim, objetivo deste estudo examinar o papel que a qualidade da vinculação aos pares, professores e funcionários da instituição desempenha na promoção da resiliência em adolescentes institucionalizados. Os dados foram recolhidos junto de 45 adolescentes (18 rapazes e 27 raparigas), com idades compreendidas entre os 10 e os 20 anos, em regime de acolhimento institucional prolongado. Para o efeito foram utilizados um breve questionário sociodemográfico, o Child and Youth Resilience Measure – 28 – versão para Jovens (Liebenberg, Ungar & Van de Vijver, 2012; versão portuguesa Ferreira & Nobre-Lima, 2013), o Inventory of Parent and Peer Attachment Revised (Armsden & Greenberg, 1987; versão portuguesa Figueiredo & Machado, 2008) – versão para Pares e Professores – e o Questionário de Ligação aos Professores e Funcionários (Mota & Matos, 2005). Ainda que tenham sido encontradas correlações significativas entre a resiliência e cada uma das variáveis em estudo, a percepção de vinculação aos pares e aos funcionários da instituição sobressaem como as variáveis que melhor explicam a resiliência nestes adolescentes, em particular nos rapazes. Já nas raparigas, a única variável que parece explicar a resiliência é a percepção de vinculação aos funcionários da instituição. A discussão explora estes resultados em termos do seu significado e implicações práticas. / Being resilient implies the ability to positively adapt to contexts of great adversity. This ability depends on a variety of factors (individual, relational and contextual) that are mostly non operative among the adolescents whose development was compromised by maltreatment. When protected by residential care these adolescents rest on peers, teachers and residential caregivers to find the care, support and encouragement they need to improve their sense of wellbeing. Therefore, the aim of this study was to examine how attachment to peers, teachers and residential caregivers can contribute to foster resilience in institutionalized adolescents. Data was collected from a sample of 45 adolescents (18 boys and 27 girls), aged between 10 and 20 years old, under extended placement in an institution. The PI is composed by a brief social-demographic questionnaire, the Child and Youth Resilience Measure – 28 – Youth version (Liebenberg, Ungar & Van de Vijver, 2012, Portuguese version Ferreira & Nobre- Lima, 2013), the Inventory of Parent and Peer Attachment Revised (Armsden & Greenberg, 1987; Portuguese version Figueiredo & Machado, 2008) – Peers and Teacher’s version – and the Questionnaire of the Affective Relationship with Teachers and Employees (Mota & Matos, 2005). Although findings showed significant correlations between resilience and each one of the variables in study, the perception of attachment to peers and residential caregivers stood out as the most correlated variables to resilience among these adolescents, mainly among the boys. Conversely, the only variable that seems to explain resilience among girls is the perception of attachment to residential caregivers. The discussion explores the possible meaning and practical implications of these findings.

Some protected special spaces on behalf of fundamental rights to the environment and the housing at the city of Natal are fragile by facing actions and attempts to suppress and changing (or omission in the implementation) of standards in furtherance of those rights at the local level, which seems to reflect a situation that goes beyond the context of the city. Based on integrated approach of the housing rights and the environment and its protection of special spaces on the field of fundamental rights, the thesis seeks to understand the weaknesses that affect the legal state duty under the realization/implementation of fundamental rights to the environment and housing in cities, focusing on the issues of flexibility of the founding legislation of special spaces to the detriment of the attributes they protected and the lack of implementation of the legal system that allows their effectiveness. So, it looks initially to understand the environment and housing rights and their special protected areas in the brazilian legal system, looking forward the evolution of its legal protection, as well as the weaknesses that emerge in the field of their effectiveness. Analyzing the trajectory of the environment and housing rights and their special protected areas in Natal, considering its standards, attributes, protection indicators, weaknesses and negative evidence within its legal protections and their enforcement by state entity, this thesis proposes to verify the existence of forms to confronting the weaknesses founded in the maintenance of legal protection and its implementation. At this point it discusses the legal basis and safeguard instruments of protection, especially within the juridical field, as part of a (re)discussion about issues of legislative and administrative discretion in the face of objective legal state duty to realization/implementation of fundamental rights in the urban space. With all these issues together the thesis does not ignore the scenario where the dividing line between public and private (economic) are becoming ever more tenuous in the field of state action and where the city stands as a special commodity to the reproduction of real estate, according to the interests of capitalist logic

O Rio Grande Sul destaca-se no cenário nacional como grande produtor de diversas culturas, as quais demandam grande quantidade de agrotóxicos das mais diversas classes químicas e toxicidades. No entanto a intensa utilização destes compostos torna-se uma preocupação devido a possíveis contaminações das águas superficiais e subterrâneas. Em virtude da degradação dos mananciais a água mineral passou a ser uma das fontes mais utilizadas para o consumo humano, pois tem-se a percepção de que a mesma possui melhor qualidade que a água tratada, além disso acredita-se que a mesma esta isenta de substâncias orgânicas prejudiciais à saúde humana. Neste trabalho, foi realizada a determinação dos agrotóxicos atrazina, simazina, imazapique, imazetapir, imidacloprido, ciproconazol, tebuconazol e epoxiconazol em água mineral empregando a Microextração Líquido-Líquido Dispersiva (DLLME), Microextração Líquido-Líquido Dispersiva com Solidificação da Gota Orgânica Flutuante (DLLME-SFO) e Cromatografia Líquida acoplada à Espectrometria de Massas em série com fonte de ionização por Eletronebulização (LC-ESI-MS/MS). Para o método empregando DLLME e LC-ESI-MS/MS foram otimizados alguns fatores como o tipo e volume de solvente extrator e dispersor e pH. Após a otimização dos parâmetros de extração, fragmentação dos compostos e separação cromatográfica, o método foi validado avaliando-se curva analítica, linearidade, limites de detecção e quantificação, precisão (repetitividade e precisão intermediária) e exatidão (recuperação). Todas as curvas analíticas apresentaram valores de r maiores que 0,999. Os Limites de Quantificação (LOQs) para o método estiveram na faixa de 5 a 500 ng L-1. Foram obtidas recuperações entre 102 - 120% para a repetibilidade e entre 92 e 110% para a precisão intermediária, com RSD de 2 a 10% para todos os compostos. Para o método empregando DLLME-SFO e LC-ESI-MS/MS foram avaliados alguns parâmetros que afetam a eficiência da extração como, tipo e volume de solvente extrator e dispersor, força iônica e pH. Nas condições ótimas de extração todas as curvas analíticas apresentaram valores de r maiores que 0,997. Os LOQs para o método variaram entre 12,5 - 125 ng L-1. As recuperações foram entre 70 e 118% para a repetitividade e entre 76 e 95% para a precisão intermediária, com RSD de 2 a 18% para todos os compostos. Com relação ao Efeito Matriz (EM) avaliado para todos os compostos pelos dois métodos, foi observado baixo EM. Isso indicou que não é necessário utilizar a curva analítica preparada no extrato branco da matriz para a quantificação destes analitos. Ambos os métodos foram aplicados para a determinação de resíduos de agrotóxicos em amostras de água mineral provenientes de diferentes regiões do estado do Rio Grande do Sul e não foram encontrados resíduos de agrotóxicos nas amostras analisadas. Os métodos validados apresentaram como principais vantagens baixo consumo de solventes orgânicos e amostra, rapidez, altos fatores de concentração e recuperações dentro da faixa aceitável. Os limites de quantificação dos métodos ficaram abaixo dos limites máximos de resíduos permitidos pela legislação brasileira para agrotóxicos em água mineral.

El ecoturismo en esencia es una actividad responsable dentro de áreas protegidas o parques nacionales, es razonable suponer que el impacto generado en la vida silvestre sería el mínimo posible. Sin embargo es muy poca la información existente relacionada con la cuantificación del impacto generado por este en ecosistemas protegidos. En esta investigación, se analizó la variación en la composición del ensamblaje de escarabajos necro-coprófagos en cuatro sitios con diferente grado de perturbación (de menor a mayor paso de personas) producto del ecoturismo en el parque nacional El Imposible. Se realizaron seis muestreos entre los meses de junio a noviembre del 2013, utilizando 20 trampas de caída en cada sitio, 10 cebadas con excremento humano y 10 con carroña de pollo. Se capturaron 10, 500 individuos pertenecientes a 22 especies. El índice de similaridad fue alto (0.90), demostrando iguales niveles de dominancia, mientras que el índice de Jaccard fue capaz de separar los sitios con acceso turístico de los sitios sin acceso. Dos especies dominaron el ensamblaje: Onthophagus landolti (excremento) y Coprophanaeus corythus (carroña). A medida que aumentó el paso de personas la riqueza (F=4.376, p=0.0048) y la abundancia (F=6.4330, p=0.0032) tendieron a descender, mientras que la diversidad (F=3.3117, p=0.0230), equitatividad (F=3.5892, p=0.0220) y biomasa (F=1.9003, p=0.1435) tendieron a aumentar a medida que el disturbio lo hacía, aunque las diferencias en biomasa no fueron estadísticamente significativas. Diferentes estudios han propuesto que el número de personas que transitan por un lugar juega un papel muy leve al afectar la vida silvestre, por lo que esta investigación podría significar un aporte al conocimiento del impacto que puede generar esta variable, ya que se observaron variaciones significativas en la composición del ensamblaje de escarabajos.
