Esta dissertação visa ampliar a discussão sobre comunicação e meio ambiente no fortalecimento de marcas e na consolidação da boa imagem das corporações. O estudo foi feito por meio de pesquisas qualitativas com algumas das mais importantes empresas em atividade no Brasil, representantes de segmentos emblemáticos, e que demonstraram já se utilizar não apenas dos apoios à preservação da natureza, mas, de uma maneira mais ampla, do cumprimento da responsabilidade social para ganharem credibilidade perante o consumidor e a sociedade, num exercício de transcendência simbólica em que não há culpados. A mudança de foco ocorrida na década de 1980, quando as companhias decidiram fortalecer suas marcas, e não mais a produção de bens, mostrou-se, do ponto de vista das corporações, ser uma alternativa muito interessante para elevar ganhos...(AU)

The environmental movement rises up strongly in the year 1972 with the Stocolmus Conference, in the middle of pressions concerning the environmental preservation, in consequence of the environmental catastrophes. In spite of the fact that, in Brazil, the environmental movement has is institutionalization with the 1988 Constitution, in a way that the councils became democratic spaces, and provided the society’s participation in the management of public policies. In this way, we propose a discussion about the participation and the exercise of the citizenship in the State Council of Environment of Rio Grande do Norte (CONEMA), focusing the glance about the decisory process, as from the expression of the social actors. For that, our research compilate documents of the meetings of the referring council, transcribing the main discussions about the environmental necessities which were important in the potiguar society, and checking how these agents defend their interest during the meetings. We understand, with these informations, the role of CONEMA/RN as a communicative mechanism between State and Society. With the analysis of the informations of the extraordinary meetings from 2007 to 2014, we concluded that the CONEMA is a council where the civil organized society takes part on the decisory process, despite the great influence of the representative actors of public power over the representative actors of civil society. The results of this research confirm the discrepancy between the participation of representative councilors of civil society in CONEMA/RN. The conclusion point out that the civil society representative don’t, yet, assimilate the citizen duty, the responsibility of it1s action, producing, in this way, damages for the legal structure of the potiguar environmental legislation, with serious consequences on the public policy implementation

The matrix of this dissertation research permeates the design of complex environmental education. Its purpose is the realistic utopia of sustainability focused on the elucidation of a cultural model, a way of life that can guarantee the preservation of the living and non-living wight, to compose a world in which all coexist in harmony. To do so, thinking that model permeates the understanding that we are nature. This understanding can be evidenced both in Karl Marx in his book, the Economic and Philosophical Manuscripts says: "Nature is the essential body of the human being", and Joël de Rosnay, in his book The Symbiotic Man explains that we humans, "are the neurons of the earth." In this same perspective, Elisabet Sahtouris, in his book The Dance of the Earth, has pointed out how little is accurate to say that "there is life on Earth," because we are knowledgeable that our planet is a living organism, then there is the "life of the Earth ". Thus, we are part of this life, we are a part of the whole. With long experience in the environmental field, I seek the collective understanding that environmental education is a process belonging to all areas of knowledge, while margins for its subdivision occasion that begins the role of librarian I am, as a mediator of educational, cultural process, and disseminate information, is an environmental educator. Research conducted lead me to propose a revision of values and attitudes, from a certain reorganization of thought, an ecology of ideas and action, evidenced by readings of education and complexity, especially tuned to the writings of Edgar Morin. This thesis makes use of metaphor as a cognitive operator to emphasize the solar cycle, linking it to the development stages of this work. In summary, we have as a goal to emphasize the importance of the human condition, respect for nature and the principle of natural, cultural and social interdependence. In order for us to have a society that values relationships of solidarity with each other, respect and gratitude for living beings and Mother Earth. What leads me to converge, the reframing of the environment, understanding it as Integer Environment

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 work is to demonstrate the scope of modern-day major regulatory provisions and the policies implemented to adoption of biofuels in the national energy matrix. The adoption of biofuels as an alternative to fossil fuels, is based on the realization of the fundamental right to an ecologically balanced environment mitigating hazards and environmental hazards arising from a postmodern society. However, the change in the Brazilian energy matrix observe the precepts of certain environmental principles to essentially environmental preservation The proposed Environmental rule of law is founded on the realization of the right (duty) key to an ecologically balanced environment for sustainable development. Thus, it is up to the State, in addition to considering the dangers and risks fruits of government decisions, present the possible instruments to mitigate the irreversible environmental damage to the environment. The management of environmental risks present in the ideals of an Environmental rule of law, plays an important role in the preservation and economic development, using, therefore, of acautelatórios legal instruments, such as environmental licensing and the ecological-economic zoning, measures adopted in the light of the principles of precaution and preservation. The adoption of research in the environmental field, improvement and development of environmental technology, building a system to observe ecological changes, imposition of environmental policy objectives to be achieved in the medium and long term and systematization of organizations plan a protection policy environmental, are essential measures to control possible environmental risks and damage guided by the aforementioned environmental principles. Thus, it will be used the inductive method of approach, starting from the analysis of the new perspective of Environmental rule of law and the implementation of biofuels in the context of a post-modern society, marked by uncertainty and the risk of damage, from the study of the principles of caution, maintaining and cautionary measures in mitigating the hazards and potential risks.

A região da Serra Gaúcha é uma importante área de produção de uvas e vinhos no sul do Brasil e busca reconhecimento através das Indicações Geográficas (IG) para vinhos finos. A preservação ambiental constitui um requisito importante para definir uma IG. No contexto de um projeto de pesquisa desenvolvido na Embrapa Uva e Vinho, um dos objetivos foi localizar áreas de preservação permanente (APPs) de acordo com o Código Florestal Brasileiro, com o auxílio de técnicas de sensoriamento remoto e geoprocessamento no intuito de identificar os vinhedos em APPs. Para isto foi utilizado o mosaico de fotografias aéreas com resolução espacial de 2 metros. Foi gerado o modelo digital de elevação da rede de drenagem, sendo as áreas de vinhedos obtidas a partir do cadastro de vinhedos pré-existentes do município. A partir do cruzamento das áreas dos vinhedos com as APPs, foram identificados 31% dos vinhedos em área de conflito.

As Áreas de Preservação Permanente foram instituídas para preservar o meio ambiente, devendo estar cobertas pela vegetação natural. Esta cobertura vegetal minimiza os impactos negativos ao meio ambiente, como processos erosivos, lixiviação dos solos, assoreamento de cursos d’água, contribuindo assim, para a regularização do fluxo hídrico. De outra forma, com a ausência dessa cobertura vegetal ocorre-se aceleradamente a degradação ambiental.

Resumen: La fertilización nitrogenada y la utilización de fungicidas son herramientas que posee el productor de cebada (Hordeum vulgare) para aumentar el rendimiento y cumplir los requerimientos exigidos por malterías. Los objetivos de estudio consisten en: a) comparar la respuesta en rendimiento, proteína y calibre a dos aplicaciones de fungicida vs. una aplicación en hoja bandera; b) comparar la respuesta en rendimiento, proteína y calibre de la aplicación de nitrógeno (N) en macollaje y en Z 3.9 vs. la aplicación de N en macollaje solamente. Se utilizó la variedad de cebada cervecera C 61 en un DBCA, con 4 repeticiones y 5 tratamientos: testigo (1); urea en macollaje (2); urea en macollaje y N en Z 3.9 (3); urea en macollaje, N y fungicida en Z 3.9 (4); urea en macollaje, N en Z 3.9, fungicida en 3.1 y 3.9 (5). Respecto al rendimiento, el tratamiento 5 promedió 3470 kg ha-1 y superó significativamente a los tratamientos 1, 2 y 3 en 42%, mientras que el tratamiento 4 rindió 3312 kg ha-1, siendo superior en un 36% a estos tratamientos, y fue un 5% menor con respecto al 5. Evaluando el porcentaje proteico, el tratamiento 4 alcanzó el valor más alto con 12 puntos porcentuales de proteína en grano y fue 9% superior a los tratamientos 1 y 3, mientras que a los tratamientos 2 y 5 los superó significativamente por 13%. En la evaluación de granos retenidos en la zaranda de 2,5 mm, los tratamientos 4 y 5 promediaron 90%, superando significativamente al tratamiento 2 en 16%. Los tratamientos 1 y 3 promediaron 83% y fueron inferiores a los tratamientos 4 y 5 en 9%. La aplicación de fungicida produjo mayores rendimientos y calibres más altos, comparándolos con los tratamientos que sólo recibieron fertilización nitrogenada. La fertilización nitrogenada en macollaje aumentó el rendimiento, pero produjo menores porcentajes proteicos y calibres más bajos. La aplicación de fungicida y N en Z 3.9 produjo los mayores rendimientos y mejores parámetros de calidad exigidos por la industria

Este estudio muestra el análisis de emergía para Nicaragua para los años 1995-99. Los objetivos del presente trabajo son 1) conocer cuáles son las principales características del sistema económico y ambiental de Nicaragua haciendo uso de índices de emergía para describir la carga ambiental y la sostenibilidad del sistema, b) determinar cuál es la posición internacional de Nicaragua en términos de su sistema ecológico-económico y e) determinar cuál es la contribución del medio ambiente de Nicaragua a la economía del país, utilizando la metodología de análisis de emergía. Emergía (con m), es la cantidad de energía que es requerida para hacer algo, es la memoria de energía la cual fue degradada en su proceso de transformación. La metodología de análisis de emergía es útil en donde el crecimiento económico está generando controversia sobre el desarrollo de la economía y la protección del medio ambiente. En este trabajo se presenta un diagrama general de sistema para Nicaragua 1995-99 y una evaluación de emergía de la Base de recursos para Nicaragua. Los resultados indican que la fuente de emergía de la base de recursos para Nicaragua es la energía potencial química en la lluvia (275.97 E+20 sej/año) y se confirma que los recursos renovables más importantes son el ganadero (91.56 E+20 sej/año) y el agrícola (62.26 E+20 sej/año). La relación de emergía exportada a importada fue de 2.14/1, ubicando a Nicaragua como un país productor de recursos. Los diferentes índices calculados para Nicaragua (Relación Emergía/USD = 15.8 E+12 sej/año; Relación de Carga Ambiental =0.39; Relación de Inversión de Emergía= 0.21; Relación de Rendimiento Neto= 5.36 e Indice de Sostenibilidad = 13.86) demuestran que Nicaragua posee una economía subdesarrollada, con niveles tecnológicos pobres y baja intensidad de desarrollo económico. Los índices también indican una baja posición de Nicaragua en la jerarquía económica de naciones. La evaluación y análisis de emergía puede ser utilizado para determinar en términos cuantitativos como realizar de forma óptima y sostenible un buen manejo de los recursos naturales, la población y la economía de una región o país, en este caso de Nicaragua.

Resumen: En este trabajo, sostenemos que América Latina está atravesando un ciclo de protesta ambiental, como resultado de dos fuerzas opuestas. Por un lado, el aumento del apetito global por los recursos naturales –alimentos, fibras, minerales, energía– ha intensificado la presión sobre el ambiente en la región. Tras décadas de globalización neoliberal, las empresas transnacionales son actores clave en estos procesos. Por otro lado, la sociedad civil y los movimientos sociales están bien organizados y son muy activos en términos de la respuesta a los riesgos sociales y ambientales derivados de los mismos, tanto en términos de los recursos materiales como de los discursivos de que disponen. Nuestro análisis se sitúa en la confluencia de tres perspectivas teóricas: la teoría de los sistemas mundiales, la política contenciosa y la resistencia a las tecnologías.
