As perspectivas ambiental e socioambiental do desenvolvimento sustentável sinérgico e sua aplicabilidade

Horn, Luiz Fernando Del Rio 17 December 2009 (has links)
O que são o desenvolvimento sustentável, seus desdobramentos teóricos e suas implicações, pode não suscitar muitas dúvidas ao investigador da academia, mas sua aplicação real vem provocando intensos debates nas muitas ciências, em razão dos temas que o cercam: quase tudo pertinente ao sistema social, para não dizer tudo. A extensão de qualquer enfrentamento a tal tema não permite grandes concessões e exceções das diversas áreas do conhecimento, sob pena de incompletude de observação, esta por si naturalmente limitada ao seu ponto cego. Assim, alguns pontos latentes para o desenvolvimento sustentável foram alinhados nos respectivos capítulos, de maneira que, no último, o somatório de revisões redunda num representativo avanço. A iniciar, e por meio do resgate histórico crítico, buscou-se a melhor definição para o desenvolvimento sustentável na contemporaneidade. Esta é observada em veias reflexivas na sequência, para contextualização do leitor nesta modernidade avançada. O processo produtivo de consumo, com ênfase para este último, detém toda a atenção a seguir, permitindo o conhecimento das engrenagens econômicas motivacionais. Dando continuação, aborda-se o desenvolvimento sustentável sob o prisma do sistema jurídico brasileiro, no qual a matriz do direito entra em discussão. Por fim, faz-se uma revisão minuciosa dos principais movimentos e correntes ambientais e socioambientais, prestando-se para a revisão do desenvolvimento sustentável, agora sinérgico. / What is the maintainable development, their theoretical unfolding and their implications, it cannot raise a lot of doubts to the investigator of the academy, but its real application is provoking intense debates in a lot of sciences, in reason of the themes that surround it: almost everything pertinent to the social system, for not saying everything. The extension of any confronting of such a theme does not allow great concessions and exceptions of several areas of knowledge, under penalty of observation uncompleted, this for itself limited naturally to its blind point. Like this, some latent points for the maintainable development were aligned in the respective chapters, so that, in the last, the sum of revisions is redundant in a representative progress. In the first chapter, through the critical historical rescue, the best definition was looked for the maintainable development in the contemporaneousness. This is observed in reflexive veins in the second chapter, for contextualization of the reader in this advanced modernity. The productive process of consumption, with emphasis for this last one, stops all the attention in the chapter third, allowing the knowledge of the gears economical motivations. In the four there is an approach of the maintainable development under the prim of the brazilian legal system, in which the head office of the right enters in discussion. In the fifth and last, it is made a meticulous revision of the main movements and environmental currents and social environments, being rendered for revision of the maintainable development, now synergic.

Assessing the adaptive capacity of Sweden's environmental governance

Tomas, Cusicanqui January 2016 (has links)
Different challenges arising from increasingly uncertain and unpredictable environmental and economicconditions have been shifting the focus of public governance and socio-economic development. Morerecently, empirical studies have demonstrated a transitional epoch in which humanity is currently in: TheAnthropocene, as well as its harmful effects that degrade the biosphere, and thus our economic, political,social well-being. The casual dynamics of climate change and its impacts on life-supporting ecosystemshas increasingly been recognized by a resilient approach which incorporates adaptive processes andschemes, allowing public governance to embrace the changes rather than control uncertainty. Thisresearch introduces the interwoven concepts of adaptive capacity, adaptive governance, and resiliencewithin a social and environmental framework. It provides a review of how these concepts support aparadigm shift to mitigating current and future challenges—understood through a multidisciplinaryapproach, and how scholars have sought to develop a blueprint to improve the need to foster and mobilizeadaptive capacity within the governance of the commons. In Sweden, key governmental and businessleaders have shown the ability to foster environmental governance that is capable of developing analternative form of planning, implementing, and managing public policy. Moreover, Sweden’s concertedmultilevel governance and public policy efforts have promoted an all-encompassing generational, mainlythrough: coordinated environmental policies and private, public, and civil society partnerships. Theseinitiatives have led to innovative technologies and projects (e.g. urban vertical farming technology) as wellas cross collaboration and integration of companies and industries in order to achieve economic, social,and environmentally symbiosis.

Stewardship in an urban world : Civic engagement and human–nature relations in the Anthropocene

Enqvist, Johan January 2017 (has links)
Never before have humans wielded a greater ability to alter and disrupt planetary processes. Our impact is becoming so noticeable that a new geological epoch has been proposed – the Anthropocene – in which Earth systems might no longer maintain the stable and predictable conditions of the past 12 millennia. This is particularly evident in the rapid expansion of urban areas, where a majority of humans now live and where environmental changes such as rising temperatures and habitat loss are happening faster than elsewhere.  In light of this, questions have been raised about what a more responsible relationship between humans and the rest of the planet might look like. Scholars in sustainability science employ the concept of ‘stewardship’ in searching for an answer; however, with multiple different applications and definitions, there is a need to better understand what stewardship is or what novelty it might add to sustainability research. This thesis investigates stewardship empirically through two case studies of civic engagement for protecting nature in cities – Bengaluru, India and New York City, USA. Further, the thesis also proposes a conceptual framework for how to understand stewardship as a relation between humans and the rest of nature, based on three dimensions: care, knowledge and agency. This investigation into stewardship in the urban context uses a social–ecological systems approach to guide the use of mixed theory and methods from social and natural sciences. The thesis is organized in five papers. Paper I reviews defining challenges in managing urban social–ecological systems and proposes that these can more effectively be addressed by collaborative networks where public, civic, other actors contribute unique skills and abilities. Paper II and Paper III study water resource governance in Bengaluru, a city that has become dependent on external sources while its own water bodies become degraded and depleted.Paper II analyzes how locally based ‘lake groups’ are able to affect change through co-management arrangements, reversing decades of centralization and neglect of lakes’ role in Bengaluru’s water supply.Paper III uses social–ecological network analysis to analyze how patterns in lake groups’ engagements and collaborations show better fit with ecological connectivity of lakes.Paper IV employs sense of place methods to explore how personal bonds to a site shapes motivation and goals in waterfront stewardship in New York City. Finally,Paper V reviews literature on stewardship and proposes a conceptual framework to understand and relate different uses and underlying epistemological approaches in the field. In summary, this thesis presents an empirically grounded contribution to how stewardship can be understood as a human–nature relation emergent from a deep sense ofcare and responsibility, knowledge and learning about how to understand social–ecological dynamics, and theagency and skills needed to influence these dynamics in a way that benefits a greater community of humans as others. Here, the care dimension is particularly important as an underappreciated aspect of social–ecological relations, and asset for addressing spatial and temporal misalignment between management institutions and ecosystem. This thesis shows that care for nature does not erode just because green spaces are degraded by human activities – which may be crucial for promoting stewardship in the Anthropocene. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript.

Une approche interdisciplinaire de la pertinence et de la faisabilité d'une co-gestion de la pêche récréative sur l'île d'Oléron : l'étrille, Necora puber (Linnaeus, 1767), comme modèle biologique / An interdisciplinary approach to assess the relevancy and feasibility of recreational fishing co-management on Oléron island : a target species, the velvet swimming crab (Necora puber, Linnaeus, 1767)

Coz, Richard 17 September 2013 (has links)
Parmi les nombreuses activités exercées sur les systèmes socio-écologiques littoraux, la pêche récréative a connu un essor important devenant ainsi un enjeu de développement durable. En France, les défauts de gouvernance de l'État dans la gestion du DPM invitent à s'interroger sur la pertinence et la faisabilité d'une co-gestion de ces pratiques de loisir. Ce paradigme, se voulant une alternative à une gestion top-down, prône la participation accrue des populations locales dans la gestion de l'environnement pour améliorer ses résultats. L'île d'Oléron ne déroge pas à ces constats qui sont renforcés par les modifications sociétales spécifiques aux territoires insulaires. Dans le cadre de recherches dont l'objet d'étude est une problématique sociétale, il est approprié de faire appel à une approche interdisciplinaire pour améliorer la pertinence des réponses apportées. Concernant la pêche à pied récréative à l'étrille, les résultats obtenus en biologie et en écologie mettent en évidence des caractéristiques qui semblent indiquer un faible impact potentiel à court comme à long termes de ces perturbations ponctuelles sur les populations locales. D'un point de vue sociétal, la pertinence d'une co-gestion de la pêche récréative est clairement établie par les nombreux conflits d'usages impliquant les pêcheurs récréatifs, le manque de moyens pour gérer la pratique et acquérir des données scientifiques, le manque de concertation, etc. La dynamique de développement du territoire oléronais et les initiatives locales à l'instar des conflits d'usages soutiennent l'idée de l'existence d'une « fenêtre politique » pouvant permettre la mise en place d'une co-gestion de la pratique dans les prochaines années, sous réserve d'une communication suffisante et d'une réelle volonté des acteurs concernés par la gestion de la pratique. / Among several other activities practice on coastal socio-ecological system, recreational fishing ones have significantly increased over the past few years, becoming an issue for sustainable development. In France, the weakness of states governance concerning DPM management, questions the relevancy and feasibility of a co-management policy for these leisure activities. This paradigm, constituting a good substitute for top-down management, recommends an increased participation of local populations for managing environments and improving their outcomes. Oléron Island is thus affected by these observations, which are intensified by societal changes distinguishing island territories. In the current research context, aiming at solving societal problematic, it is relevant to consider an interdisciplinary approach to provide relevant answers. Concerning recreational shellfish gathering targeting the velvet swimming crab, results in biology and ecology highlight some characteristics which should indicate a weak short and long terms potential impact of the disturbances affecting local populations. As regards to societal aspects, the relevancy of co-management is clearly demonstrated by several land-use conflicts, a lack of means to manage the practice and scientific data, the lack of consultation, etc. The territorial dynamic and local initiatives, as well as land-use conflicts, underline the existence of a “political window” which should allow the implementation of a co-management process for recreational fishing in the following years, subject to further efficient communication and a real desire from stakeholders concerned by the management of this practice.

Situation analysis of perceptions on comprehensiveness of rape prevention interventions by implementing agencies in Addis Ababa

Difabachew Setegn Hailegeorgis 02 1900 (has links)
Abstract in English, Xhosa and Afrikaans / The victimization of women and children represents one of the public health problems deserving urgent attention in Ethiopia, making the prevention of rape in all its forms a matter of vital importance. The purpose of the study was mainly to describe the extent of rape prevention interventions in Addis Ababa and examine efforts to assist rape survivors based on the perceptions of professionals working for organizations operating in this context. The study had a further purpose of identifying difficulties faced by government institutions and making suitable recommendations for the improvement of rape prevention interventions and programs in the future. A qualitative descriptive research approach was adopted mainly involving in-depth interviews for primary data collection. The study involved 14 research participants purposively selected from five government institutions. The study findings indicated Gandhi Memorial Hospital to be the only institution in Ethiopia implementing an integrated rape prevention intervention. Efforts were directed largely at secondary prevention, with little attention being paid to primary prevention. Recommendations included tackling the multiple factors influencing rape at different levels of the social-ecological model simultaneously through the implementation, strengthening, and intensification of well-designed, comprehensive rape prevention interventions and programs. / Ukuxhatshazwa kwabafazi nabantwana e-Ethiopia kufana nenye yeengxaki zempilo kwaye kudinga ukuthathelwa ingqalelo ngokungxamisekileyo. Oku kwenza ukuba ukuthintela ukudlwengulwa ngazo zonke iindlela kube ngumbandela obaluleke kakhulu. Injongo yesi sifundo ibikukucacisa iindlela zokuthintela ukudlwengulwa eAddis Ababa, nokuvavanya imizamo yokunceda abo bakhe badlwengulwa, ngokokubona kwabo basebenzela amaqumrhu aququzelela lo msebenzi. Enye injongo yesi sifundo ibikukuchonga ubunzima obufunyanwa ngamaziko aseburhulumenteni ajongene neli candelo ukuze kunikwe iingcebiso zokuphucula amacebo neenkqubo zokuthintela ukudlwengulwa. Kuqhutywe uhlobo lophando lomgangatho nolucacisayo, apho kuqokelelwe iinkcukacha zolwazi ngokwenza udliwano ndlebe olunzulu. Kusetyenzwe nabathathi nxaxheba abali-14 abakhethwe ngobuchule kumaziko aseburhulumenteni ama-5. Okufunyaniswe sesi sifundo kubonakalise ukuba isibhedlele esiyiGandhi Memorial siso sodwa esinenkqubo elungelelaniswe kakuhle yokuthintela ukudlwengulwa. Imigudu yokhukhusela ijoliswe ekuncedeni kwiziqhamo zodlwengulo nasekufundiseni ngodlwengulo (secondary prevention) hayi kudlwengulo ngqo (primary prevention). Amacebiso esifundo aquka ukulwa neemeko eziphembelela udlwengulo olwenzeka kumazinga ahlukeneyo oluntu, ngaxeshanye nokuqinisa ukusetyenziswa kweenkqubo eziqulunqwe kakuhle zokuthintela udlwengulo. / Die viktimisering van vroue en kinders is een van talle kwessies in die openbare gesondheid van Ethiopië wat dringend aandag vereis, aangesien die voorkoming van verkragting in enige vorm van die allergrootste belang is. Die doel van hierdie studie was om die omvang te bepaal van intervensies om verkragting in Addis Abeba te voorkom, en om die hulp wat aan verkragtingslagoffers verleen word, te ondersoek op grond van die belewenisse van beroepslui wat in hierdie verband vir organisasies werk. Hierdie studie het dit verder ten doel gehad om die probleme aan te toon waarmee staatsinstellings in hierdie opsig te kampe het, en om beter intervensies en programme vir die voorkoming van verkragting aan te beveel. ʼn Kwalitatiewe en deskriptiewe navorsingsbenadering is gevolg. Dit het omvattende onderhoude behels waartydens primêre data versamel is. Altesame 14 deelnemers by vyf staatsinstellings is vir hierdie doel gekies. Volgens die bevindings is die Gandhi Gedenkhospitaal die enigste instelling in Ethiopië wat ʼn geïntegreerde program vir die voorkoming van verkragting ingestel het. Sekondêre voorkoming geniet voorrang, terwyl primêre voorkoming min aandag geniet. Daar word aanbeveel dat tegelykertyd werk gemaak word van die veelvuldige faktore wat verkragting op verskillende vlakke van die sosiaal-ekologiese model beïnvloed. Dit moet gedoen word deur deeglik ontwerpte, omvattende intervensies en programme om verkragting te voorkom in werking te stel, uit te bou en te verskerp. / Sociology / M.A. (Sociology)

Remote Sensing for sustainable and resilient Cities / New Pathways to support social-ecological Systems in Change

Wellmann, Thilo 06 June 2023 (has links)
Klimawandel und Biodiversitätsverlust sowie Verstädterung und demografischer Wandel haben tiefgreifende Auswirkungen auf Städte und ihre Ökosysteme und damit auf die Lebensbedingungen der Mehrheit der Menschheit. Die Geschwindigkeit des Wandels und die Dringlichkeit der Folgen macht Umweltmonitoring zu einem potentiell interessanten Tool für nachhaltige und resiliente Stadtentwicklung. Der erste Artikel gibt einen Überblick über den aktuellen Stand der Fernerkundung in Bezug auf Stadtökologie und zeigt, dass Fernerkundung relevant für nachhaltige Stadtplanung ist. Es bestehen jedoch bestehen Mängel, da viele Studien nicht direkt umsetzbar sind. Der zweite Artikel zeigt, dass eine wachsende Stadt Möglichkeiten für den Ausbau der grünen Infrastruktur bieten kann. Im dritten Artikel wird untersucht, wie sich die städtische Dichte auf die Bereitstellung von Ökosystemdienstleistungen der grünen Infrastruktur auswirkt. Es wird gezeigt, dass eine hohe Siedlungsdichte nicht zwangsläufig zu einem geringeren Biodiversitätspotenzial oder einer geringeren Kühlkapazität führt. Allerdings sind dicht bebaute Gebiete mit geringer Vegetationsbedeckung besonders auf grüne Infrastruktur angewiesen. Der vierte Artikel befasst sich mit der Frage, wie naturbasierte Lösungen durch eine bessere Vernetzung der Beteiligten gestärkt werden können. Auf der Grundlage einer gezielten Literaturrecherche über Informationstechnologie zur Unterstützung sozial-ökologischer Systeme wird ein Instrument zur Entscheidungshilfe entwickelt. Dieses kombiniert ökologische und soziale Indikatoren, um Klimawandeladaption in Übereinstimmung mit den sozio-ökologischen Bedingungen entwickeln zu können. Der fünfte Artikel bietet eine grundsätzliche Perspektive zur Unterstützung der städtischen Nachhaltigkeit, die auf dem ökologischen-Trait Konzept basiert. Zusammen bieten die fünf Artikel Wege für die Fernerkundungswissenschaft und die angewandte Raumplanung für nachhaltige und resiliente Entwicklungen in Städten. / Climate change and biodiversity loss, as well as urbanisation and demographic change, are major global challenges of the 21st century. These trends have profound impacts on cities and their ecosystems and thus on the living conditions of the majority of humanity. This raises the need for timely environmental monitoring supporting sustainable and resilient urban developments. The first article is an overview of the state of the art of remote sensing science in relation to urban ecology. The review found that remote sensing can contribute to sustainable urban policy, still insufficiencies remain as many studies are not directly actionable. The second article shows that a growing city can provide opportunities for an increase in green infrastructure. Here, remote sensing is used for long-term analysis of land-use in relation to urban forms in Berlin. The third article examines how urban density affects ecosystem service provision of urban green infrastructure. It is shown that residential density does not necessarily lead to poor biodiversity potential or cooling capacity. However, dense areas with low vegetation cover are particularly dependent on major green infrastructure. The fourth article explores ways to reinforce nature-based solutions by better connecting and informing stakeholders. Based on a focussed literature review on information technology supporting urban social-ecological systems, a decision support tool is developed. The tool combines indicators based on ecological diversity and performance with population density and vulnerability. This way, climate change adaptation can be developed in accordance with socio-ecological conditions. The concluding fifth article offers an outlook on a larger framework in support of urban sustainability, based on the ecological trait concept. Together the five research papers provide pathways for urban remote sensing science and applied spatial planning that can support sustainable and resilient developments in cities.

Unravelling the Making of Real Utopias / Debates on ‘Great Transformation’ and Buen Vivir as Collective Learning Experiments towards Sustainability

Beling, Adrian Eugenio 13 August 2019 (has links)
Die immer offensichtlicher werdende Verflechtung der vielfältigen sozialen und ökologischen Krisen stellt Risikogesellschaften weltweit vor der Herausforderung, grundlegende Transformationen der vorherrschenden gesellschaftlichen Modelle und Lebensweisen vorzunehmen, welche sich an den kulturellen Vorstellungen des wohlhabenden globalen Nordens orientieren. Bisher haben sich jedoch sowohl internationale als auch lokale Versuche, globale Entwicklungspfade in Richtung „faire und nachhaltige“ Zukunft zu lenken, als weitgehend erfolglos erwiesen. Der weltweite Ressourcenverbrauch und die Degradierung der Biosphäre haben sich weiter verschärft und beschleunigt. In Anlehnung an die deutsche hermeneutische Tradition sowie an den französischen Poststrukturalismus und den amerikanischen symbolischen Interaktionismus versucht diese theoretische und empirische Dissertation, die strukturellen Zwänge zu modellieren, mit denen individuelle change agents konfrontiert sind, und sie daran hindern, sozial-ökologische "reale Utopien" (Bloch) voranzutreiben. Darüber hinaus nimmt diese Dissertation eine Typisierung möglicher Wege zur Überwindung solcher Einschränkungen vor, nämlich durch Eingriffe einer bestimmten Art von auf der meso-gesellschaftlichen Ebene operierender Agency, die wir als Para-Governance bezeichnen. Die Dissertation schließt mit einer Reflexion über die sich verändernden Formen und Funktionen von Governance im Anthropozän, die über herkömmliche, eng definierte rationalistische und institutionalistische Ansätze hinausgehen. / The increasingly apparent imbrication of the multiple social and ecological crises creates an imperative for “risk societies” worldwide to undertake fundamental transformations to the currently prevalent model of social organization shaped after the cultural imaginaries of the affluent Global North. So far, however, both international and local attempts at bending global developmental trajectories towards “fair and sustainable” futures have proven largely futile, with global resource-consumption and biosphere degradation further reinforcing and accelerating. Drawing on the German hermeneutic tradition, as well as on French post-structuralism and American symbolic interactionism, this theoretical cum empirical dissertation seeks to model the structural constraints weighting over ‘change agents’, thus preventing them from advancing social-ecological “real utopias” (Bloch), and typify possible ways of overcoming such constraints through interventions of a specific kind of agency identified as operating at the meso-societal level, which we refer to as para-governance. The dissertation concludes by reflecting on the changing forms and functions of governance in the Anthropocene beyond conventional narrowly defined rationalist and institutionalist approaches.

The experiences of elderly women (goGogetters) in assisting orphans and vulnerable children affected by HIV and AIDS at Musina in the Limpopo Province

Phaka, Mpudi Elizabeth 10 1900 (has links)
Text in English / Even though the prevalence of HIV has declined, South Africa continues to have a large number of people who are infected with HIV. Most communities still have to deal with the effects of HIV and AIDS on orphans and vulnerable children. One way of mitigating the effects of HIV and AIDS is strengthening families and communities to provide stable care to orphans. However, most families do not have the capacity to provide sufficient care to orphans hence the need for external support from the community and civil society organisations, in this instance provided through the loveLife goGogetter programme. The findings proved that the goGogetters relied on the support they received through the relationships and networks established in the community to enable them to provide effective service to orphans. The study demonstrated the importance of community networks in providing for the basic needs of orphans. / Social Work / M.A. (Social Behaviour Studies in HIV/AIDS)
