Catalonia's energy metabolism : Using the MuSIASEM approach at different scales

This paper applies the so-called Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM), based on Georgescu-Roegen's fund-flow model, to the Spanish region of Catalonia. It arrives to the conclusion that within the context of the end of cheap oil, the current development model of the Catalan economy, based on the growth of low-productivity sectors such as services and construction, must be changed. The change is needed not only because of the increasing scarcity of affordable energy and the increasing environmental impact of present development, but also because of the aging population. Moreover, the situation experienced by Catalonia is similar to that of other European countries and many other developed countries. This implies that we can expect a wave of major structural changes in the economy of developed countries worldwide. To make things more challenging, according to current trends, the energy intensity and exosomatic energy metabolism of Catalonia will keep increasing in the near future. To avoid a reduction in the standard of living of Catalans due to a reduction in the available energy it is important that the Government of Catalonia implement major adjustments and conservation efforts in both the household and paid-work sectors

Why Catalonia will see its energy metabolism increase in the near future : an application of MuSIASEM

This paper applies the so-called Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) to the economy of the Spanish region of Catalonia. By applying Georgescu-Roegen's fund-flow model, it arrives at the conclusion that within a context of the end of cheap oil, the current development model based on the growth of low productivity sectors such as services and construction must change. The change is needed not only because of the increasing scarcity of affordable energy carriers, or because of the increasing environmental impact that the present development represents, but also because of an ageing population that demands labour productivity gains. This will imply industry requiring more energy consumption per worker in order to increase its productivity, and therefore its competitiveness. Thus, we conclude that energy intensity, and exosomatic energy metabolism of Catalonia will increase dramatically in the near future unless major conservation efforts are implemented in both the household and transport sectors

El flujo de materiales y el desarrollo económico en España: un análisis sobre desmaterialización (1980-2004)

El análisis de los flujos de materiales que circulan a través de un sistema económico es una forma de medir la dimensión física del consumo y la apropiación de recursos por parte de una sociedad y, en consecuencia, es una manera indirecta de medir su impacto ambiental. De esta manera, los indicadores de flujos de materiales pueden ser considerados como indicadores indirectos de sostenibilidad, y por tanto, pueden ser de utilidad para comprobar la hipótesis de la desmaterialización; es decir, la idea de que el progreso tecnológico conlleva una disminución del total de materiales usados (desmaterialización fuerte) o de los materiales usados por unidad de producción (desmaterialización débil). Este artículo presenta la contabilidad de flujos de materiales para España entre 1980 y 2004. Asimismo, analiza la hipótesis de la curva de Kuznets ambiental usando el consumo de materiales como indicador de impacto ambiental. El análisis revela que durante el periodo analizado no tuvo lugar ningún proceso de desmaterialización, ni fuerte ni débil. Aunque la población no se incrementó considerablemente, los materiales movilizados por la economía española (las entradas directas de materiales, EDM) se duplicaron, creciendo a tasas anuales por encima del PIB. Además, se constata que en términos físicos España pasó a ser más dependiente del comercio exterior. De hecho, las importaciones netas medidas en toneladas se duplicaron durante el periodo.Material flow analysis (MFA) is a means of measuring the social metabolism, or physical dimensions of a society's consumption, and can be taken as an indirect and approximate indicator of sustainability. Material flow accounting can be used to test the dematerialisation hypothesis, the idea that technological progress causes a decrease in total material used (strong dematerialisation) or material used per monetary unit of output (weak dematerialisation). This paper provides the results of a material flow analysis for Spain for the period from 1980 to 2004. In addition, the environmental Kuznets curve hypothesis is analysed in this paper, using material consumption as an indicator of global environmental impact. The analysis reveals that neither strong nor weak dematerialisation took place during the period analysed. Although the population did not increase considerably, materials mobilised by the Spanish economy (Direct Material Input, or DMI) doubled, surpassing GDP growth. In addition, Spain became more dependent on external trade in physical terms. In fact, its net imports more than doubled during the period in terms of weight

Material flow accounting of Spain

Material throughput is a means of measuring the so-called social metabolism, or physical dimensions of a society's consumption, and can be taken as an indirect and approximate indicator of sustainability. Material flow accounting can be used to test the dematerialisation hypothesis, the idea that technological progress causes a decrease in total material used (strong dematerialisation) or material used per monetary unit of output (weak dematerialisation). This paper sets out the results of a material flow analysis for Spain for the period from 1980 to 2000. The analysis reveals that neither strong nor weak dematerialisation took place during the period analysed. Although the population did not increase considerably, materials mobilised by the Spanish economy (DMI) increased by 85% in absolute terms, surpassing GDP growth. In addition, Spain became more dependent on external trade in physical terms. In fact, its imports are more than twice the amount of its exports in terms of weight
