Macroeconomía y medio ambiente: El PIB como medida de bienestar

Este Trabajo de Fin de Grado estudia el uso del Producto Interior Bruto (PIB) como medida de bienestar. Al tiempo que se realiza el análisis de la contabilidad nacional y, en mayor profundidad del PIB, se detallan algunas medidas alternativas. Éstas han surgido como consecuencia de la búsqueda de indicadores que incluyan en sus mediciones, no solo el crecimiento económico, sino también otra serie de variables que son relevantes y que el PIB no contempla (como los recursos naturales, la contaminación, la calidad de vida o la igualdad en la distribución de la renta de un país, por ejemplo). Así, surgen nuevos indicadores como el PIB ambientalmente ajustado, el Índice de Mejor Vida, el Índice de Progreso Genuino o la Huella Ecológica, entre otros. Como resultado de este análisis se concluye que la medida que mejor refleja el bienestar depende del objetivo específico que se busque investigar. En otras palabras, hoy en día ninguna medida es capaz de contestar todas las preguntas relacionadas con el bienestar de la población. Sin embargo, el PIB no está configurado –ni fue creado- como una medida de bienestar de un país. Por lo tanto, actualmente es preciso acompañar la información de este indicador con la de otros alternativos de tal manera que podamos tener una imagen más completa sobre el nivel de bienestar de un país.

The adoption of sustainable remediation behaviour in the US and UK: a cross country comparison and determinant analysis.

The sustainable remediation concept, aimed at maximizing the net environmental, social, and economic benefits in contaminated site remediation, is being increasingly recognized by industry, governments, and academia. However, there is limited understanding of actual sustainable behaviour being adopted and the determinants of such sustainable behaviour. The present study identified 27 sustainable practices in remediation. An online questionnaire survey was used to rank and compare them in the US (n=112) and the UK (n=54). The study also rated ten promoting factors, nine barriers, and 17 types of stakeholders' influences. Subsequently, factor analysis and general linear models were used to determine the effects of internal characteristics (i.e. country, organizational characteristics, professional role, personal experience and belief) and external forces (i.e. promoting factors, barriers, and stakeholder influences). It was found that US and UK practitioners adopted many sustainable practices to similar extents. Both US and UK practitioners perceived the most effectively adopted sustainable practices to be reducing the risk to site workers, protecting groundwater and surface water, and reducing the risk to the local community. Comparing the two countries, we found that the US adopted innovative in-situ remediation more effectively; while the UK adopted reuse, recycling, and minimizing material usage more effectively. As for the overall determinants of sustainable remediation, the country of origin was found not to be a significant determinant. Instead, organizational policy was found to be the most important internal characteristic. It had a significant positive effect on reducing distant environmental impact, sustainable resource usage, and reducing remediation cost and time (p<0.01). Customer competitive pressure was found to be the most extensively significant external force. In comparison, perceived stakeholder influence, especially that of primary stakeholders (site owner, regulator, and primary consultant), did not appear to have as extensive a correlation with the adoption of sustainability as one would expect.

Towards Eco-Dharma: The Contribution of Gandhian Thought to Ecological Ethics in India

Ecological concern prompts poor and indigenous people of India to consider how a society can ensure both protection of nature and their rightful claim for a just and sustainable future. Previous discussions defended the environment while ignoring the struggles of the poor for sustenance and their religious traditions and ethical values. Mohandas Karamchand Gandhi addressed similar socio-ecological concerns by adopting and adapting traditional religious and ethical notions to develop strategies for constructive, engaged resistance. The dissertation research and analysis verifies the continued relevance of the Gandhian understanding of dharma (ethics) in contemporary India as a basis for developing eco-dharma (eco-ethics) to link closely development, ecology, and religious values. The method of this study is interpretive, analytical, and critical. Françoise Houtart’s social analytical method is used to make visible and to suggest how to overcome social tensions from the perspective of marginalized and exploited peoples in India. The Indian government's development initiatives create a nexus between the eco-crisis and economic injustice, and communities’ responses. The Chipko movement seeks to protect the Himalayan forests from commercial logging. The Narmada Bachao Andolan strives to preserve the Narmada River and its forests and communities, where dam construction causes displacement. The use of Gandhian approaches by these movements provides a framework for integrating ecological concerns with people's struggles for survival. For Gandhi, dharma is a harmony of satya (truth), ahimsa (nonviolence), and sarvodaya (welfare of all). Eco-dharma is an integral, communitarian, and ecologically sensitive ethical paradigm. The study demonstrates that the Gandhian notion of dharma, implemented through nonviolent satyagraha (firmness in promoting truth), can direct community action that promotes responsible economic structures and the well-being of the biotic community and the environment. Eco-dharma calls for solidarity, constructive resistance, and ecologically and economically viable communities. The dissertation recommends that for a sustainable future, India must combine indigenous, appropriate, and small- or medium-scale industries as an alternative model of development in order to help reduce systemic poverty while enhancing ecological well-being.

Energy systems and their impacts on marine ecosystem services

Global warming and its link to the burning of fossil fuels has prompted many governments around the world to set legally binding greenhouse gas reduction targets which are to be partially realised through a stronger reliance on renewable (e.g. wind) and other lower carbon (i.e. natural gas and nuclear) energy commodities. The marine environment will play a key role in hosting or supporting these new energy strategies. However, it is unclear how the construction, operation and eventual decommissioning of these energy systems, and their related infrastructure, will impact the marine environment, the ecosystem services (i.e. cultural, regulating, provisioning and supporting) and in turn the benefits it provides for human well-being. This uncertainty stems from a lack of research that has synthesised into a common currency the various effects of each energy sector on marine ecosystems and the benefits humans derive from it. To address this gap, the present study reviews existing ecosystem impact studies for offshore components of nuclear, offshore wind, offshore gas and offshore oil sectors and translates them into the common language of ecosystem service impacts that can be used to evaluate current policies. The results suggest that differences exist in the way in which energy systems impact ecosystem services, with the nuclear sector having a predominantly negative impact on cultural ecosystem services; oil and gas a predominately negative impact on cultural, provisioning, regulating and supporting ecosystem services; while wind has a mix of impacts on cultural, provisioning and supporting services and an absence of studies for regulating services. This study suggests that information is still missing with regard to the full impact of these energy sectors on specific types of benefits that humans derive from the marine environment and proposes possible areas of targeted research.

Bridging the gap between energy and the environment

Meeting the world’s energy demand is a major challenge for society over the coming century. To identify the most sustainable energy pathways to meet this demand, analysis of energy systems on which policy is based must move beyond the current primary focus on carbon to include a broad range of ecosystem services on which human well-being depends. Incorporation of a broad set of ecosystem services into the design of energy policy will differentiates between energy technology options to identify policy options that reconcile national and international obligations to address climate change and the loss of biodiversity and ecosystem services. In this paper we consider our current understanding of the implications of energy systems for ecosystem services and identify key elements of an assessment. Analysis must consider the full life cycle of energy systems, the territorial and international footprint, use a consistent ecosystem service framework that incorporates the value of both market and non-market goods, and consider the spatial and temporal dynamics of both the energy and environmental system. While significant methodological challenges exist, the approach we detail can provide the holistic view of energy and ecosystem services interactions required to inform the future of global energy policy.

Chapter 11: Human activities and ecosystem service use: impacts and trade-offs

Ecosystem services provided by the marine environment are fundamental to human health and well-being. Despite this, many marine systems are being degraded to an extent that may reduce their capacity to provide these ecosystem services. The ecosystem approach is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way (UN Convention on Biological Diversity, 2000). Its application to marine management and spatial planning has been proposed as a means of maintaining the economic and social value of the oceans, not only in the present but for generations to come. Characterising the susceptibility of services (and combinations of services) to particular human activities based on knowledge of impacts on biodiversity and ecosystem functioning (as described in preceding chapters) is a challenge for future management of the oceans. In this chapter, we highlight the existing, but limited knowledge of how ecosystem services may be impacted by different human activities. We discuss how impacts on one service can impact multiple services and explore how the impacts on services can vary both spatially and temporally and according to context. We focus particularly on the effects on ecosystem services of activities whose impacts on biodiversity and ecosystem functioning have already been considered in previous chapters. Some of these activities are associated with poor management of ecosystem benefits, for example, from provisioning services (aquaculture and fisheries), or with excessive input of wastes, fertilisers and contaminants into the system overburdening the waste treatment and assimilation services. Other impacts are associated with the construction of structures or use of space designed to generate benefits from environmental services such as the presence of water as a carrier for shipping, or sources of wind, wave and tidal power. We discuss the trade-offs that are made, consciously or otherwise, between different ecosystem services, which arise from human activities to optimise or manage specific ecosystem services.

Agricultura urbana, condición para el desarrollo sostenible y la mejora del paisaje

Este artículo resulta de investigaciones en torno al “enverdecimiento” de las ciudades y las oportunidades de la agricultura urbana para la alimentación de una población en constante aumento que no trabaja la tierra. También es fruto de actividades de mejora de ambientes urbanos realizadas con la Escuela de Ingenieros Agrónomos de la Universidad Politécnica de Madrid. A través de casos de agricultura urbana, entendiendo por ella el conjunto de prácticas para la producción de alimentos y plantas ornamentales dentro de las ciudades y en sus entornos, se analizan alternativas para la recuperación de espacios construidos e incremento de la calidad de vida de la población. Todo ello se traduce, además, en creación de riqueza y mejora del paisaje urbano, siempre desde criterios de sostenibilidad que favorecen el desarrollo local desde la Cumbre de la Tierra de Río de 1992 y la Conferencia sobre Desarrollo Sostenible Río+20 de 2013.

Empirical testing of genuine savings as an indicator of weak sustainability: a three-country analysis of long run trends

Genuine Savings has emerged as a widely-used indicator of sustainable development. In this paper, we use long-term data stretching back to 1870 to undertake empirical tests of the relationship between Genuine Savings (GS) and future well-being for three countries: Britain, the USA and Germany. Our tests are based on an underlying theoretical relationship between GS and changes in the present value of future consumption. Based on both single country and panel results, we find evidence supporting the existence of a cointegrating (long run equilibrium) relationship between GS and future well-being, and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables. This provides some support for the GS measure of weak sustainability. We also show the effects of modelling shocks, such as World War Two and the Great Depression.

Effective indoor air quality for energy-efficient homes: a comparison of UK rating systems

The use of sustainable assessment methods in the UK is on the rise, anticipating the future regulatory trajectory towards zero carbon by 2016. The indisputable influence of sustainable rating tools on UK building regulations conveys the importance of evaluating their effectiveness in achieving true sustainable design, without adversely effecting human health and wellbeing. This paper reviews indoor air-quality (IAQ) issues addressed by UK sustainable assessment tools, and the potential trade-offs between building energy conservation and IAQ. The barriers to effective adoption of IAQ strategies are investigated, including recommendations, suggestions, and future research needs. The review identified a fundamental lack of IAQ criteria in sustainable assessment tools aimed at the residential sector. The consideration of occupants’ health and well-being should be paramount in any assessment scheme, and should not be overshadowed or obscured by the drive towards energy efficiency. A balance is essential.

Ciências no primeiro ciclo do ensino básico : um programa para educação para desenvolvimento sustentável

Num planeta finito, a impossibilidade de um crescimento contínuo e a necessidade de preservar os seus recursos naturais e ambientais, tendo em vista assegurar opções de qualidade de vida e bem-estar das gerações futuras, fez emergir e estruturar o conceito de Desenvolvimento Sustentável. Perante os múltiplos desafios que o futuro coloca, a educação constitui-se como uma via para alcançar um desenvolvimento mais harmonioso das relações entre os seres humanos e entre estes e a natureza, indispensável à humanidade na persecução dos seus legítimos anseios de paz, liberdade e justiça social. A importância atribuída à educação no sentido de uma adequada perceção da situação do planeta levou as Nações Unidas a proclamarem, no início deste século (dezembro de 2002), a Década da Educação para o Desenvolvimento Sustentável (2005-2014): um desafio internacional lançado aos países para que recorram à educação como ferramenta essencial na promoção de Desenvolvimento Sustentável. A vida nas sociedades contemporâneas é, como nunca antes, influenciada por desenvolvimentos científicos e tecnológicos e dependente dos respetivos progressos. Assim, a Educação Científica assume um papel fundamental na compreensão das problemáticas que enfrentamos e na consciencialização da responsabilidade do ser humano na situação planetária atual, devendo promover o desenvolvimento de cidadanias proativas, fundamentadas e responsáveis, no sentido da mudança, numa perspetiva crítica global que garanta a sustentabilidade do planeta. Estas finalidades são alvo de reflexão por parte de diversas instâncias da sociedade – nas quais se incluem organismos como a UNESCO, comunidades nacionais e internacionais de investigação em Educação Científica, e o poder político – e espelham-se em propostas de reforma e de revisão curricular em diversos países. Ora, sem ser exclusiva, a educação formal nos primeiros anos de escolaridade tem um papel fundamental, por ter caráter obrigatório na maioria dos países. Paralelamente existe um crescente reconhecimento a nível internacional em torno da importância de se iniciar precocemente a Educação Científica com vista a alcançar esses propósitos. Resultados alcançados em diversas investigações evidenciam que a Educação Científica nos primeiros anos de escolaridade tem impacte positivo relevante no desenvolvimento de literacia científica e no desenvolvimento de atitudes positivas face à Ciência e a aprendizagens de Ciências. A presente investigação pretende ser um contributo para a Década da Educação para o Desenvolvimento Sustentável no Primeiro Ciclo do Ensino Básico. O percurso de investigação, de natureza qualitativa, foi desenvolvido em três fases distintas mas articuladas entre si: a fase I integrou processos interpretativos de investigação documental e teve como principais objetivos o estabelecimento do quadro teórico de suporte à problemática de Educação para Desenvolvimento Sustentável e a caraterização de perspetivas de Educação Científica decorrentes de política educativa em Portugal; na fase II caraterizou-se a importância atribuída por professores do Primeiro Ciclo do Ensino Básico à Educação Científica e respetiva componente experimental, bem como as suas conceções acerca de Literacia Científica, orientações Ciência-Tecnologia-Sociedade no ensino das Ciências, Desenvolvimento Sustentável e o modo como dizem articular as referidas conceções com as suas práticas de sala de aula; na fase III apresentou-se um Programa de Ciências, concebido segundo os referenciais atrás definidos e avaliado por um painel de peritos, para Educação para Desenvolvimento Sustentável, “A Terra e os seres vivos: conhecer para valorizar e proteger”, para implementação em cada um dos quatro anos de escolaridade do Primeiro Ciclo do Ensino Básico. O presente estudo assume-se como um contributo para a inovação na Educação Científica no Primeiro Ciclo do Ensino Básico e fundamenta a necessidade de a reorientar, tendo em vista a resposta a compromissos internacionais assumidos por Portugal no âmbito da Década da Educação para o Desenvolvimento Sustentável, bem como a importância de acompanhar orientações e políticas recomendadas a nível internacional, numa perspetiva de educação num contexto de globalização.

New Ways of Being a Man: “Positive” Hegemonic Masculinity in Meditation-based Communities of Practice

Connell’s concept of hegemonic masculinity is often reduced to a singular construct, consisting of “toxic” traits viewed as detrimental to well-being. However, the concept allows for variation in hegemony, including the possibility of forms more conducive to well-being. Through in-depth interviews with thirty male meditators in the United Kingdom, we explored the social dimensions of meditation practice to examine its potential implications for well-being. Most participants became involved with “communities of practice” centered on meditation that promoted new local hegemonies, and these included ideals experienced as conducive to well-being, like abstinence. However, social processes associated with hegemony, like hierarchy and marginalization, were not overturned. Moreover, participants faced challenges enacting new practices in relation to the broader system of hegemonic masculinity—outside these communities—reporting censure. Our findings are cautionary for professionals seeking to encourage well-being behaviors: that is, there is potential for adaptation in men, yet complex social processes influence this change.

Improving health and wellbeing independently of GDP: dividends of greener and prosoical economies

Increases in gross domestic product (GDP) beyond a threshold of basic needs do not lead to further increases in well-being. An explanation is that material consumption (MC) also results in negative health externalities. We assess how these externalities influence six factors critical for well-being: (i) healthy food; (ii) active body; (iii) healthy mind; (iv) community links; (v) contact with nature; and (vi) attachment to possessions. If environmentally sustainable consumption (ESC) were increasingly substituted for MC, thus improving well-being and stocks of natural and social capital, and sustainable behaviours involving non-material consumption (SBs-NMC) became more prevalent, then well-being would increase regardless of levels of GDP. In the UK, the individualised annual health costs of negative consumption externalities (NCEs) currently amount to £62 billion for the National Health Service, and £184 billion for the economy (for mental ill-health, dementia, obesity, physical inactivity, diabetes, loneliness and cardiovascular disease). A dividend is available if substitution by ESC and SBs-NMC could limit the prevalence of these conditions.

Sustentabilidade dos Georrecursos: Proposta de Definição de Índice de Sustentabilidade para Pedreiras Produtoras de Agregados

As atuais políticas industriais procuram conjugar os objetivos económicos com direitos sociais e ambientais através da aplicação de políticas de desenvolvimento sustentável. A gestão coordenada destes três capítulos visa contribuir para o bem‐estar e progressiva melhoria da qualidade de vida dos cidadãos. Esta Tese de Mestrado tem por objetivo a aplicação de um sistema de avaliação de pedreiras produtoras de agregados partindo da análise integrada de indicadores setoriais nas áreas económica, social e ambiental. Deste modo é proposto o desenvolvimento de um método de avaliação que permita proceder a uma análise qualitativa e quantitativa do desempenho de pedreiras do ponto de vista da sua sustentabilidade. Numa abordagem inicial, enquadradora das questões que se levantam com as políticas de desenvolvimento sustentável, é feita uma introdução relativa às correntes de pensamento dominantes sobre esta questão, tendo ainda sido feito um relacionamento entre as questões ligadas com o planeamento estratégico deste setor industrial e as questões ligadas com o ordenamento do território. Posteriormente, é feita uma análise do enquadramento do setor extrativo relativo à exploração de pedreiras no âmbito das políticas económicas, sociais e ambientais da Comunidade Europeia e uma caracterização da importância deste setor industrial na economia portuguesa. Após o desenvolvimento destas questões, é dada sequência ao trabalho desenvolvido na adoção e criação de indicadores económicos, sociais e ambientais adaptados à situação particular das pedreiras produtoras de inertes portuguesas. Finalmente, é proposto o desenvolvimento de um método de cálculo tendo em vista a criação de um Índice de Sustentabilidade a partir da análise dos resultados dos indicadores setoriais anteriormente referidos. Assim, é apresentada uma súmula de conclusões sobre este tipo de abordagem, suas vantagens e inconvenientes relativamente aos métodos tradicionais de avaliação deste tipo de indústria. É, por último, apresentado um conjunto de sugestões que permitam a utilização na rotina, de forma acessível, desta nova ferramenta de análise.
