In this work we apply the method of two-dimensional time-lapse electrical resistivity tomography (2D time-lapse ERT) for two different problems. In the first problem, we monitor the structural stability of the roof of the Great Hall cavern in the Harrison's cave system, Barbados. We present an interpretation and comparison of two sets of resistivity data collected over the Great Hall: one set collected by us in 2010, the other in 1996. Our results show that fracturing and degradation had progressed since 1996, indicating a gradual weakening of the structural stability of the roof of the Great Hall cavern. In the second problem, we conduct 2D ERT surveys during dry and rainy seasons to evaluate the potential and feasibility of groundwater exploration next to the Thomazo River in the Fond D'Or watershed in Saint Lucia. Interpretation of the ERT data sets reveals a lens of a porous rock that has a high potential to be a productive aquifer. We use the ERT time-lapse approach to evaluate the change in water content between dry and wet seasons in the potential aquifer.

Texto completoThe question investigated in this study is whether the framework ‘planetary boundaries’ can be a suitable tool for improving sustainability performance at companies or not. It does so by investigating three analytical and eight related empirical questions. The methods in this study include; a structural literature review, qualitative interviews with key players at the focal company Sandvik Materials Technology and a qualitative analysis of the steel industry and Sandvik Materials Technology’s relationship to planetary boundaries. From the literature study, it was concluded that as for now, methods for applying the planetary boundary framework lack in maturity. It does not follow from this that there is no scientific relevance in developing methods for application, but more research is needed to confirm a methodological framework for application which is suitable for companies. The interviews revealed a skeptical attitude towards the framework´s ability to improve Sandvik Materials Technology´s sustainability performance. To derive environmental targets from science was viewed as a necessity, however environmental targets in companies must take other aspects (e.g. cost-effectiveness and business opportunity) into account as well. The qualitative Planetary Boundaries analysis showed that the activities and processes at Sandvik Materials Technology is well suited for an environmental assessment based on a planetary boundaries perspective. Some focus areas remained the same as in their current environmental strategy (e.g. climate change and fresh water abstraction) but others (biosphere integrity and biochemical flows) appeared as new possible focus areas. Sandvik Materials Technology´s main focus, resource use, were however excluded from an environmental assessment based on a planetary boundaries perspective. Due to the lack of mature methods, an implementation of the framework at a company requires a strong commitment at the company. The researcher concludes that such level of commitment is lacking at Sandvik Materials Technology. Therefore, this study reaches the conclusion that the planetary boundary framework is, at least for now, not alone a suitable tool for improving sustainability performance at the focal company Sandvik Materials Technology.
Melim, Ema Margarida Gonçalves. "Achieving a planetary health diet: red meat and legumes availability in Portugal". Bachelor's thesis, [s.n.], 2019. http://hdl.handle.net/10284/8520.
Texto completoAims: The global food system has strong implications in the depletion of natural resources, biodiversity loss, greenhouse gas emissions and climate change. To face the current challenges, a planetary health diet was recently proposed by the EAT-Lancet Commission, serving as a guide to the implementation of diets aligned with the environmental boundaries of the planet. The aim of this paper is to compare the planetary health diet recommendations with the current consumption of legumes and red meat in Portugal, exploring different policy strategies that promote healthy and environmentally sustainable eating patterns in the country. Methods: Data from the Food and Agriculture Organization’s Food Balance Sheets regarding legumes and red meat supply was used, as well as Statistics Portugal data for production and consumption of red meat, and National Food, Nutrition and Physical Activity Survey concerning consumption of both legumes and red meat. Results: The national consumption of red meat is four times above (68g/day) the recommendations for a healthy and sustainable diet while legumes consumption is three times below (24g/day) what is recommended, reflecting a nutritional transition to a westernized food pattern, both unhealthy and unsustainable. Conclusions: Integrated policies that promote increased information and awareness regarding sustainable diets and effective changes in the food environment that facilitate sustainable food choices by consumers are essential to support a dietary shift in the country towards plant-based diets aligned with the planetary boundaries and sustainable development goals.
Objetivos: O sistema alimentar global tem fortes implicações na degradação ambiental do planeta e alterações climáticas. Recentemente, foi proposta uma dieta de saúde planetária pela EAT-Lancet Commission que serve de referência para a promoção de padrões alimentares alinhados com os limites ambientais do planeta. O objetivo deste estudo é analisar o consumo de leguminosas e de carne vermelha em Portugal no âmbito da recente referência planetária, explorando possíveis estratégias políticas que promovam a transição para uma alimentação ambientalmente mais sustentável no país. Metodologias: Foram utilizados dados das Balanças Alimentares da Food and Agriculture Organization relativos à disponibilidade de leguminosas e carne vermelha, dados estatísticos do Instituto Nacional de Estatística sobre produção e consumo de carne vermelha, e dados do Inquérito Alimentar Nacional e de Atividade Física relativamente ao consumo de leguminosas e carne vermelha. Resultados: O consumo nacional de carne vermelha encontra-se aproximadamente quatro vezes acima (68g/d) das recomendações para uma dieta de saúde planetária enquanto que o consumo de leguminosas se encontra três vezes abaixo (24g/d) do recomendado, refletindo uma transição nutricional para um padrão alimentar mais ocidentalizado, pouco saudável e insustentável. Conclusões: Políticas integradas que promovam a informação e a sensibilização para uma alimentação sustentável e a modificação do ambiente alimentar que facilite escolhas mais sustentáveis pelos consumidores são essenciais para que o padrão alimentar em Portugal se aproxime da dieta planetária, contribuindo ainda para os objetivos de desenvolvimento sustentável e alterações climáticas.

Texto completoBakgrund Företagens aktiviteter fortsätter att vara särkopplade från vetenskapen om Jordens globala system och till vilken utsträckning företagen motverkar kollaps av Jordens system är oklart (Whiteman et al. 2014) och det är denna utmaning som denna uppsats söker att utforska genom att koppla företagens hållbarhetsarbete med Jordens 9 gränser genom at utveckla SIQ modellen. Syfte Syfte med denna uppsats är att utveckla SIQ modellen så den innehåller det som krävs för att företagen skall identifiera sin inverkan på Jordens 9 gränser. Metod En kvalitativ metod har använts och för att analysera har gjorts genom att använda Jordens 9 gränser och top-down/bottom-up perspektivet som lins för att identifiera problem, lösningar och analysen av SIQ modellen och datainsamlingen har gjorts genom litteraturstudier. Resultat Resultatkapitlet introducerar en modell som visar samverkan mellan Jordens system och 9 gränser ner till företagen aktiviteter. Modellen följs av analysen av SIQ modellen som visar störst utvecklingspotential i miljöledningskriterierna. Utvecklingen bör samverka med top-down/bottom-up perspektiven för att modellen skall på bästa sätt omhänderta externa faktorer såsom Jordens gränser i styrningen av företagen på överordnad och utförarnivå. Diskussion För att företagen skall kunna omhänderta alla externa faktorer såsom Jordens gränser så måste SIQ kriterierna och företagens mål samverka. Genom att integrera Jordens gränser med SIQ modellen så har gapet mellan företagen och miljövetenskapen minskats. Genom att minska detta gap kan företagens aktiviteter bidra till att minimera nerbrytningen och risk för kollaps av Jordens system.

Texto completoVäxande ekologiska utmaningar [1][2][3] kan adresseras av medieindustrin genom proaktivt engagemang i holistisk hållbarhetstransformation som täcker alla aktiviteter i värdekedjan. Då minst 60% av arterna bland ryggradsdjur redan har försvunnit [1] och 40% av insektsarterna riskerar att försvinna [2], har tiden för konventionellt företagande (business-as-usual) passerat [4][5][6][49]. För att minska negativa effekter, och accelerera positiva effekter, vad gäller den biologisk mångfaldens integritet, måste företagen se bortom direkta effekter, koldioxidutsläpp, och isolerade åtgärder för en mer holistisk förståelse av och ett mer holistiskt angreppssätt vad gäller hållbarhetstransformation. Denna studie har fokuserat specifikt på Norden (Sverige, Norge, Danmark, Finland) och de största etablerade företagen inom denna region (Schibsted, MTG, Bonnier, Egmont och Sanoma) [7][8], för att ta reda på vilka åtgärder som behövs för att skydda både människor och planeten [10]. Genom att förstå drivkrafterna bakom förlusten av biologisk mångfald, såväl som de föreslagna färdplanerna för hållbarhetstransformation ifrån forskarsamfundet, och genom att kvantitativt analysera hur dessa fem företag förstår och prioriterar hållbarhet, har denna studie utvecklat en visuell lins [Pathway Lens] bestående av sju fokusområden (Seven Focus Areas, SFAs), för att möjliggöra för medieföretag att titta holistiskt på deras aktiviteter och värdekedja. De sju fokusområdena (SFAs) för hållbarhetstransformation måste hanteras holistiskt, likt FN:s 17 globala mål för hållbar utveckling (Agenda 2030) [4]. Eftersom etablerade nordiska medieföretag i dagsläget inte tittar på påverkan på den biologiska mångfaldens integritet, och inte heller fokuserar på ett holistiskt angreppssätt vad gäller hållbarhet, är de sju fokusområdena [SFAs] av den visuella linsen [Pathway Lens] ett verktyg för att bättre förstå deras unika möjlighet att accelerera hållbara livsstilar genom deras innehåll, marknadsplatser, samt produkter och events, vilka i sin tur adresserar påverkan på den biologiska mångfaldens integritet. Medieindustrin delar också den kollektiva möjligheten att accelerera hållbara värdekedjor genom att prioritera värderingar som transcenderar jaget (self-transcendence), resurser, ansvarsfulla verksamheter, cirkulära affärsmodeller, iterativt intressentengagemang, och externa partnerskap. Eftersom drivkrafterna bakom förlust av biologisk mångfald är komplexa och sammankopplade [3], krävs komplexa och sammankopplade lösningar för att skydda både människor och planeten.

Texto completoThe large-scale implementation of emission reduction strategies in the agriculture, forestry and other land uses (AFOLU) sector raises questions about their sustainability. For example, second-generation bio-fuels threaten biodiversity and the reforestation of agricultural land increases food prices. In addition, these emission reduction strategies are highly dependent on socio-economic conditions describing the rest of the food system (agricultural trade liberalization, economic development, population growth, etc.). For example, an increase in food demand, due to population growth and economic development, can increase pressures on the food system, leading to ecosystem degradation and increased greenhouse gas emissions. In this thesis, we seek to clarify the impacts on biodiversity, food and greenhouse gas emission of large-scale mitigation strategies in the AFOLU sector under different socio-economic conditions. To do this, we used prospective modeling to simulate various global land uses in 2030, 2050 and 2100 under different scenarios. More specifically, to study the impact of different mitigation strategies on biodiversity indicators, we coupled the Nexus Land-Use (NLU) model with the Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (PREDICTS) biodiversity model. A nitrogen balance is also built to specify the link between intensification and environmental impact.In the first chapter, we assessed the impact of scenarios of increased legume production in Europe on greenhouse gas emissions in the AFOLU sector. We found that the main environmental benefit of legumes is to provide proteins as a substitute for animal products rather than enabling a lower consumption of synthetic fertilizer through the increased leguminous nitrogen fixation. Most of the emission reduction takes place in the animal production sector and outside Europe. This first chapter also highlights the importance of indirect mechanisms that lead to a reduction in N2O emissions associated with nitrogen fertilization in the plant sector. The sensitivity of these results to different reforestation scenario led me to then focus on the interactions between mitigation strategies.In the second chapter, we analyzed the trade-offs and synergies between biodiversity and food security for different combinations of mitigation scenarios. Large-scale bioenergy production had negative effects on different biodiversity indicators (species richness and biodiversity intactness index) as well as on different food security indicators (food prices and production costs). Although presenting a trade-off between biodiversity protection and food security, a combination of diet change and reforestation scenarios can improve biodiversity and food security in many cases compared to a situation without mitigation.In a third chapter, we identified global land-use scenarios that ensure to stay within planetary boundaries in terms of nitrogen cycle, biosphere integrity, non-CO2 emissions from the AFOLU sector and forest conservation. We showed that despite the uncertainty surrounding the determination of global boundaries, the most robust environmental scenarios that ensure to stay within these global boundaries are mainly composed of reforestation, dietary changes and increased efficiency in the use of inputs in crop production

Se, por um lado, o meio ambiente é fundamental para o crescimento econômico no modelo capitalista, as crises ambientais, devido ao não respeito dos limites planetários, representam uma ameaça para humanidade. As empresas são cobradas para contribuir com a solução desse problema, por historicamente terem contribuído para essa situação. Por outro lado, ainda existem poucos estudos que tratam a sustentabilidade empresarial e seus impactos para melhorar a qualidade do meio ambiente (WHITEMAN, WALKER E PEREGO, 2013). Este estudo buscou avaliar se as estratégias de sustentabilidade do setor elétrico estão alinhadas aos principais desafios ambientais da atualidade. Para definir esses desafios, o estudo se baseou, principalmente, na teoria dos limites planetários de Steffen et al. (2015). Além de revisões bibliográficas, também foi realizada uma análise Multi Estudos de Casos, que contou com análises documentais (websites e relatórios de sustentabilidade) e entrevistas com três líderes da estratégia de sustentabilidade de empresas do setor elétrico, que são referências no tema (estão na carteira do ISE). Como resultado desse estudo, observou-se que, dos nove limites planetários (mudança do clima, integridade da biosfera, redução da camada de ozônio, acidificação dos oceanos, uso de água doce, fluxo bioquímico (nitrogênio e fósforo), alteração no território , carga de aerossol atmosférico e novos contaminantes), seis deles (mudança do clima, integridade da biosfera, alteração no território, uso de água doce, carga de aerossol atmosférico e novos contaminantes) tiveram historicamente o setor elétrico como uma de suas principais ameaças. Dois desses temas (mudança do clima e novos contaminantes) são considerados prioritários por todas as empresas estudadas. No entanto, quando se analisa o alinhamento das empresas para enfrentar os principais impactos causados pelo setor nos limítes planetários, observa-se que: I) todos os impactos relacionados ao tema ‘alteração no território’ são geridos por, ao menos, uma estratégia de cada empresa estudada; II) todos os impactos relacionados a uso de água doces e carga de aerossóis atmosféricos são gerenciados por uma ou duas das empresas estudadas; III) um ou mais impactos relacionados aos temas ‘mudança do clima’, ‘integridade da biosfera’ e ‘novos contaminantes’ não são gerenciados pela estratégia de sustentabilidade de nenhuma empresa estudada. Ao final, são sugeridos alguns estudos futuros relacionados aos temas estudados.
The environment is essential for economic growth in capitalism. In contrast, environmental crisis, due to not respecting planetary boundaries, represent a threat to humanity. Corporations are charged to help solving this problem, since historically they were the contributors of this issue. Nonetheless, there still are few studies that deal with corporate sustainability and its impacts to improve environment quality (Whiteman, Walker and Perego, 2013). This paper tried to evaluate if the sustainable strategies within the Brazilian electric Power companies are aligned with the main environmental challenges of current times. To describe these challenges, this research was mainly based on the planetary boundaries theory , done by Steffen et al. (2015). Among several bibliographic reviews, it was done a an Multiple Case Study analysis, that took into account documental reviews (websites and sustainability reports), interviews with three sustainable strategy leaders from benchmark companies of the Brazilian electric power sector (present at ISE portfolio).As a result of this research, it was realized that out of the nine planetary boundaries described (climate change, biosphere integrity, stratospheric ozone depletion, ocean acidification, freshwater use, biochemical flows (nitrogen and phosphorus), land-system change, atmospheric aerossol loading, novel entities) , the electric power sector represents a historically threat over six of them (climate change, biosphere integrity, land-system change, freshwater use, atmospheric aerossol and novel entities). The companies studied consider as a priority two of these boundaries (climate change and novel entities). Notwithstanding that, observing these companies alignment to deal with these main impacts caused by the electric sector Power on the boundaries, we can point that: I) all companies have their own strategies to manage all impacts on land-system change ; II) at least one company manages each freshwater use or atmospheric aerossol loading impacts; III) one or more impacts caused by climate change, biospheric integrity or novel entities are not dealt with any of these companies. It is possible to conclude that sustainable strategies among the Brazilian eletric power sector companies are partially aligned with the main environmental challenges of current times. Lastly, futures studies related to these cases are suggested.

Texto completoA preocupação com o meio ambiente ganhou importância nos hábitos das sociedades. Enquanto indivíduos e consumidores temos maior consciência do impacto das nossas ações sobre o planeta. Esta consciencialização global levou à mudança de paradigma e ao tipo de gestão dos negócios, assistindo-se ao aumento da preocupação ambiental por parte de governos, empresas, associações e organizações. Atendendo a que os conceitos de "marketing sustentável" e "sustentabilidade" assumem, hoje, um papel decisivo nas empresas, levantou-se a questão - "DE QUE FORMA A SUSTENTABILIDADE TEM INFLUÊNCIA NA AQUISIÇÃO DE UM PRODUTO DE COSMÉTICA?" - com o objetivo de verificar se as empresas ambientalmente responsáveis adquirem ou não, vantagem competitiva. A fim de reunir informação sobre o tema, realizou-se uma extensa pesquisa sobre sustentabilidade, desenvolvimento sustentável, marketing sustentável, vantagem competitiva, empresas sustentáveis, normas, relatórios e programas sobre o meio ambiente, consumidor verde e história da indústria cosmética. A questão central foi direcionada para a indústria de cosmética, sendo a empresa em estudo The Body Shop. A marca é mundialmente conhecida pelo uso de recursos naturais e práticas sustentáveis. Foi pioneira na relação entre as empresas e estratégias sustentáveis para a proteção do planeta. Nesta dissertação foi aplicada uma metodologia quantitativa, a fim de apurar o grau de conhecimento sobre a marca e os conceitos referidos anteriormente. Várias questões emergiram neste processo de pesquisa, sendo sugeridas para investigação futura.
The environment has become an important concern in the societies worldwide. This global awareness led to a change in the social habits and subsequently to a shift of the social paradigm and the type of business management. We can observe an increasing environmental concern by governments, companies, associations and organizations. As the concepts of sustainability in general, and the sustainable marketing in particular seem to assume a crucial role amongst companies in different sectors, a question has been raised: -"HOW DOES SUSTAINABILITY INFLUENCE THE ACQUISITION OF A COSMETIC PRODUCT?". It is intended to understand if environmentally responsible companies and with the domain of the concept of "sustainability" acquire or not, competitive advantage. In order to gather relevant information about this subject it was conducted an extensive research that focused on: sustainability, sustainable development, sustainable marketing, competitive advantage, sustainable enterprises, norms, reports and programs on the environment, green consumer and the history of cosmetics. The main question of this paper targeted the cosmetic industry, and the company under study was The Body Shop. The brand is worldwide known for using natural resources and sustainable practices. It was pioneer in the relationship between business and sustainable strategies for the protection of the planet. In this dissertation, in order to determine to what extend are both the brand and the concepts mentioned above known, it was applied a quantitative methodology. Several questions emerged from this research process and they were suggested for future research.

Texto completoPurpose: Circular economy is presented as an approach to economic growth that is in line with sustainable development. However, the recent literature has highlighted the limits of the concept in terms of environmental sustainability. The study examines the relationship between circular economy and conservation of ecosystems, using a case study on the implications of a circular economy for Slovak forests and forest sector. Design/methodology/approach: This study adopts a qualitative methodology through a focused review of the relevant literature on circular economy and sustainable development and primary data gathered through semi-structured interviews with 15 experts and practitioners in the forest sector, forest conservation and circular economy context, both from within as well as outside of Slovakia. Findings: The study finds that the forestry sector has an important role to play in a shift to a circular economy in Slovakia, with significant opportunities for improved efficiency as well as substitution of wood for non-renewable resources. There is also growing potential for ecosystem stewardship and restoration. However, the increased application of biomass could crowd out other needs, including for biodiversity. Safeguarding these services depends ultimately on good governance. Originality/value: The study highlights that circular economy taken in a narrow focus on resource efficiency is insufficient to ensure environmental sustainability but rather needs to be set within the broader environmental and social context.

Texto completoThe use of frameworks for the identification, monitoring and compensation of environmental impacts is an increasingly common practice in the business sector. The Planetary Boundaries Framework is one of the many existing frameworks, however no Portuguese company has yet implemented this model’s approach in its strategy. This study analyzes the main challenges to a hypothetical application of the models’ approach in the Portuguese companies’ strategy, as well as the main opportunities resulting from that application. The most material environmental impacts of a set of Portuguese companies were also assessed. To this end, interviews were carried out with sustainability technicians and/or specialists from four companies (Hovione, Bondalti, SUMOL+COMPAL, The Navigator Company) and the most recent sustainability report of each company was analyzed. The model would need to be further developed for companies to implement it in their strategy, since there is still an incompatibility between the global scale of the model and the scale of companies, which was the main obstacle/challenge pointed out by the interviewees. The interviewees consider as a main opportunity the fact that the model, when fully developed, can be very useful to assess and compare the environmental impact that countries or industries have on the models’ limits and components. It was also concluded that the most material environmental impacts of the four companies occur mostly at the level of industrial activity. These are water and energy consumption, effluent discharge, GHG emissions and waste generation and discharge.

The theoretical study is part of the contribution of Social Pedagogy to the issue of the Sustainability of the Planet and Academic Training Requirements. With a view of this intended to understand to what extent this concern is inscribed in the academic training of educators, particularly social pedagogues. In this sense, for the purpose of grounding the theoretical framework, we resorted to the scientific literature on the issue of the Sustainability of the Planet in a framework of Social Pedagogy, as well as the legislation considered relevant. The empirical study is part of a case study that is based on a documental analysis and on the direct questioning is centered on an initial training course for social educators offered by a higher education institution. The data collected and analyzed in this study allowed us to reaffirm our conviction that Environmental Education plays a fundamental role in Academic Training, suggesting the need for its inclusion in their training plans.

Texto completoAlready two decades before the “Brundtland” Report” was published, environmental sustainability was being served by Earth Observation (EO) images, collected by man-made satellites, and useful for meteorology, monitoring pollution, desertification and climate change. Africa took its first step into space in the 1970s. Over 700M USD have been since invested in EO satellites by African Nations, some building CubeSats on their own. Unlike in Europe, a Space Agency that would have joined African Nations’ forces never materialized. However, many environmental stakeholders in Africa use space data, and it is important to grasp why a multinational space initiative has not come into fruition, and how such cooperation could serve environmental sustainability in the region. The methodology followed combined bibliographic research and a survey made with African entities from the space and environment sectors. In the first phase, the 24 African space initiatives were analysed. This classification was made with a scale proposed by the author, which over emphasizes know-how over industrialisation and budget. Algeria, Nigeria, Egypt and South Africa were graded as the most successful. Evidence showing that EO applications can leave a positive impact on environmental sustainability in Africa and other regions in the world, a survey (undertaken in the second phase) gathered 95 responses, covering 34 of the 54 African nations. The responders were found to be knowledgeable about space initiatives, especially non-African, value space as a response to environmental sustainability challenges, and believe know-how should be a priority over technology. The underlying reasons why multinational initiatives have not succeeded in Africa, makes such type of cooperation unrealistic in space, and impossible to emulate the European Space Agency model. A roadmap is then devised to help African actors guide their space efforts towards environmental sustainability. This roadmap covers best practices for national and multinational African space initiatives, and the development of OT applications. The potential offered by drones and New Space trends are emphasized. It is considered that African space actors can achieve more success by investing in education and open data policies in order to produce information pertinent to environment stakeholders.
