Going beyond energy intensity to understand the energy metabolism of nations: the case of Argentina

The link between energy consumption and economic growth has been widely studied in the economic literature. Understanding this relationship is important from both an environmental and a socio-economic point of view, as energy consumption is crucial to economic activity and human environmental impact. This relevance is even higher for developing countries, since energy consumption per unit of output varies through the phases of development, increasing from an agricultural stage to an industrial one and then decreasing for certain service based economies. In the Argentinean case, the relevance of energy consumption to economic development seems to be particularly important. While energy intensity seems to exhibit a U-Shaped curve from 1990 to 2003 decreasing slightly after that year, total energy consumption increases along the period of analysis. Why does this happen? How can we relate this result with the sustainability debate? All these questions are very important due to Argentinean hydrocarbons dependence and due to the recent reduction in oil and natural gas reserves, which can lead to a lack of security of supply. In this paper we study Argentinean energy consumption pattern for the period 1990-2007, to discuss current and future energy and economic sustainability. To this purpose, we developed a conventional analysis, studying energy intensity, and a non conventional analysis, using the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) accounting methodology. Both methodologies show that the development process followed by Argentina has not been good enough to assure sustainability in the long term. Instead of improving energy use, energy intensity has increased. The current composition of its energy mix, and the recent economic crisis in Argentina, as well as its development path, are some of the possible explanations.

Ecoetiqueta de serveis i aprofitament dels recursos hídrics i energètics als establiments hotelers de Sitges

Aquest projecte té com a objectiu l’estudi de l’estat ambiental dels hotels del municipi de Sitges i l’estudi d’aprofitament dels recursos hídrics i energètics característics d’aquesta zona del Mediterrani per hotels de 4 i 5 estrelles. Sitges és un municipi que al període estival dobla la població, i que amb una superfície de 43,85 Km2 conta amb 35 hotels i apart pensions, hostals i càmpings, per tant, el turisme és l’activitat més important a Sitges. Per desenvolupar aquest projecte s’ha realitzat una enquesta senzilla sobre qualitat ambiental per conèixer el comportament ambiental dels diferents hotels. En aquest estudi han participat 15 dels 35 hotels del municipi, ja que el 49% d’aquests romanen tancats des d’Octubre fins a Març i dels 18 hotels restants 15 han accedit a formar part d’aquest estudi. A través d’una prova pilot s’ha avaluat la implantació del Distintiu de Garantia de Qualitat Ambiental a l’hotel Antemare i a l’hotel Sunway Playa Golf, aquests dos hotels pertanyen a la categoria de quatre estrelles, categoria que reuneix més nombre d’hotels i el tant per cent d’ocupació és major en comparació amb les altres categories. El DGQA és una ecoetiqueta de serveis que atorga la Generalitat de Catalunya a partir de la revisió de l’establiment per mitjà d’un tècnic autoritzat. S’ha analitzat l’aprofitament dels recursos local com, les aigües pluvials i la radiació solar en els hotels de 4 i 5 estrelles per obtenir l’autosuficiència individual dels 9 hotels objecte d’estudi. Els resultats obtinguts en aquest estudi reflecteixen la possibilitat de millorar l’estat ambiental dels establiments hotelers, duent a terme alguns criteris bàsics com, la recollida selectiva i una major implantació d’energies renovables, així com també la utilització d’aquestes per assolir un cert nivell d’autosuficiència energètica i hídrica. La prova pilot mostra que els dos hotels estudiats estan molt a prop d’aconseguir el DGQA, els vectors on s’haurien de fer millores són, informació ambiental, energia, aigua i residus.

Les symbioses industrielles : une nouvelle stratégie pour l'amélioration de l'utilisation des ressources matérielles et énergétiques par les activités économiques

RésuméCette thèse traite d'un domaine d'application de l'écologie industrielle, les symbioses industrielles, comme stratégie d'amélioration de la consommation des ressources matérielles et énergétiques et de la gestion des déchets par les activités économiques. Les symbioses industrielles cherchent à créer de nouvelles collaborations directement entre les acteurs économiques d'un territoire dans le but d'échanger de l'information, des matières premières et des déchets, et d'intensifier les mutualisations de services et d'infrastructures possibles entre entreprises voisines. Ces quatre types de collaboration sont représentés schématiquement dans la figure ci-dessous.Dans ce travail, la détection et la mise en oeuvre de symbioses industrielles sont abordées sous plusieurs angles. Les recherches réalisées concernent le développement de procédures de mise en oeuvre s'adressant aux collectivités publiques, aux institutions académiques et aux bureaux de conseil dans le domaine de l'environnement. Les objectifs des procédures sont de créer une dynamique de collaboration et de confiance entre les acteurs économiques et l'administration publique d'un territoire afin de détecter des symbioses industrielles potentielles. Ces procédures requièrent la gestion de grandes quantités d'informations relatives aux flux de matière et d'énergie.Un travail de terrain, réalisé sur les territoires du canton de Genève et de Lausanne Région et utilisé comme études de cas, a permis de mettre en évidence un grand nombre de symbioses industrielles qui existent déjà en Suisse romande. Plusieurs dizaines d'exemples ont été identifiés principalement dans lesdomaines de la gestion de l'eau, de l'énergie, des produits chimiques et des matériaux de construction. La législation suisse autoriserait cependant la concrétisation de nombreuses autres opportunités. Dans cette recherche, celles-ci sont évaluées techniquement, légalement, économiquement et environnementalement. La création d'un référentiel d'évaluation des opportunités permet de déterminer quelles sont les symbioses industrielles techniquement réalisables et pertinentes dans le contexte suisse et dans quels cas celles-ci représenteraient une réelle plus-value par rapport à l'utilisation actuelle de la ressource et aux filières existantes de collecte et de valorisation des déchets.Finalement, un logiciel, SymbioGIS, destiné à soutenir la détection et l'évaluation de symbioses industrielles potentielles a été développé. Il s'agit d'une interface web accessible pour de nombreux utilisateurs, couplée à une interface de systèmes d'information géographique. En plus de la détection de symbioses industrielles, plusieurs fonctionnalités sont proposées pour faciliter la prise en compte des flux de matière et d'énergie dans les problématiques liées à l'aménagement du territoire et au positionnement des activités économiques.En conclusion, cette recherche met en évidence la nécessité de rapprocher les institutions publiques en charge de la protection de l'environnement, de la promotion économique et de l'aménagement du territoire pour favoriser l'essor des symbioses industrielles comme stratégie pour la gestion des ressources matérielles et énergétiques. Elle propose des pistes pour intensifier les collaborations entre ces domaines et accélérer le partage des connaissances liées aux flux de matière et d'énergie et à leur cheminement au sein des activités économiques afin de rendre le système industriel existant en Suisse romande viable à long terme. Parallèlement, elle étudie les possibilités de transposer ces considérations et les procédures et outils développés dans le contexte économique et social de la région Asie-Pacifique, où se trouvent aujourd'hui de nombreuses activités de production.SummaryIndustrial symbioses: A new strategy for improving how economic activities use material and energy resourcesThis thesis focuses on one application of industrial ecology, industrial symbioses, as a strategy for improving how economic activities consume material and energy resources. Industrial symbioses seek to create new collaborations among economic players with the goal of exchanging information, raw materials, and waste directly among area businesses, and to step up the potential pooling of services and infrastructure among neighboring companies.The identification and implementation of industrial symbioses are studied from several angles. The research first examines the development of implementation procedures for government bodies, academic institutions, and environmental consulting services. The purpose of the procedures is to create a dynamic of collaboration and trust between the economic players and the public officials in a region in order to identify potential industrial symbioses. The procedures necessitate managing large amounts of information about material and energy flows.Fieldwork conducted in the canton of Geneva and the Lausanne region, and used as case studies for the research, highlights a great number of industrial symbioses that already exist in French-speaking Switzerland. Several dozen examples are identified, primarily in the areas of water management, energy, chemical products, and building materials; however, Swiss law would permit many others. The research evaluates these opportunities from a technical, legal, economic, and environmental standpoint. By developing an assessment framework it is possible to determine which industrial symbioses are technically feasible and pertinent in Switzerland, and under what circumstances they would represent real added value compared to the current use of the resource and to existing systems for collecting and reusing waste.Lastly, SymbioGIS software was developed to help identify and assess potential industrial symbioses. The program's Web-based interface can be accessed by multiple users and is coupled with an interface that provides geographic information. In addition to identifying industrial symbioses, several program functionalities make it easier to consider material and energy flows with regard to local development issues and siting economic activities.In conclusion, the research highlights the need to bring together public institutions charged with protecting the environment, promoting economic activity, and overseeing development in order to foster the expansion of industrial symbioses as a strategy for managing material and energy resources. It proposes solutions for stepping up collaboration among these players and accelerating the sharing of knowledge about material and energy flows and their paths within economic activities with the goal of making theexisting industrial system in French-speaking Switzerland viable long-term. Also examined were thepossibilities of transposing these considerations and the study's findings about Switzerland to the economic and social context of the Asia-Pacific region, where much production is now located.

Assessing the Precision of Compositional Data in a Stratified Double Stage Cluster Sample: Application to the Swiss Earnings Structure Survey

Precision of released figures is not only an important quality feature of official statistics,it is also essential for a good understanding of the data. In this paper we show a casestudy of how precision could be conveyed if the multivariate nature of data has to betaken into account. In the official release of the Swiss earnings structure survey, the totalsalary is broken down into several wage components. We follow Aitchison's approachfor the analysis of compositional data, which is based on logratios of components. Wefirst present diferent multivariate analyses of the compositional data whereby the wagecomponents are broken down by economic activity classes. Then we propose a numberof ways to assess precision

New structures for goat corrals to control peridomestic populations of Triatoma infestans (Hemiptera: Reduviidae) in the Gran Chaco of Argentina

Goat production is an important economic activity for rural communities in the Gran Chaco of Argentina. Goat corrals are important for the survival of peridomestic populations of Triatoma infestans. This study evaluated the impact of modifying the traditional structure of goat corrals on T. infestans populations and goat productivity in the region of Los Llanos (La Rioja). Thirty-nine experimental corrals were constructed and 57 traditional corrals were used as controls. We evaluated the infestations of the control and experimental corrals for five years following construction of the structures. The results showed that the new structures did not prevent the colonization, although it enhanced the detection of infestation at low densities of T. infestans. No significant difference was found in T. infestans population abundance between control and experimental corrals, probably because of the different detectability in the two types of structures, especially among the small nymphs. Although goat productivity average was higher in experimental than in control corrals, no significant difference was found because of high variability. The new structures can be used as a complement to promote the development of rural communities. Acceptability and adoption of the new corrals by the owners was high, as the enclosures offered better protection for the goats, increased growth of kids and facilitated herd handling.

Interpreting social enterprises

Institutional and organizational variety is increasingly characterizing advanced economic systems. While traditional economic theories have focused almost exclusively on profit-maximizing (i.e., for-profit) enterprises and on publicly-owned organizations, the increasing relevance of non-profit organizations, and especially of social enterprises, requires scientists to reflect on a new comprehensive economic approach for explaining this organizational variety. This paper examines the main limitations of the orthodox and institutional theories and asserts the need for creating and testing a new theoretical framework, which considers the way in which diverse enterprises pursue their goals, the diverse motivations driving actors and organizations, and the different learning patterns and routines within organizations. The new analytical framework proposed in the paper draws upon recent developments in the theories of the firm, mainly of an evolutionary and behavioral kind. The firm is interpreted as a coordination mechanism of economic activity, and one whose objectives need not coincide with profit maximization. On the other hand, economic agents driven by motivational complexity and intrinsic, non-monetary motivation play a crucial role in forming firm activity over and above purely monetary and financial objectives. The new framework is thought to be particularly suitable to correctly interpret the emergence and role of nontraditional organizational and ownership forms that are not driven by the profit motive (non-profit organizations), mainly recognized in the legal forms of cooperative firms, non-profit organizations and social enterprises. A continuum of organizational forms ranging from profit making activities to public benefit activities, and encompassing mutual benefit organizations as its core constituent, is envisaged and discussed.

This chapter discusses how the industrial ecological systems can help in dealing with environmental issues in developing countries, and it presents three case studies from India that highlight some of the unique environmental issues of developing world. Industrial ecology explores the assumption that the industrial system can be seen as a certain kind of ecosystem. The scope of industrial ecology goes well beyond waste exchange to the optimization of resources flowing through the economic system. Among the various specific aspects of developing countries, which have to be born in mind, is the fact that the pattern of resource flows in developing countries, and hence, the resultant environmental threat could be very different than what it is in the industrialized west. Typically, the flow of materials through the large, organized manufacturing facilities in the developing countries could be very small in relation to the overall material flow as the small, informal ?industry? plays a key role and forms a very significant portion of the economic activity. The case studies of the Tirupur textile industries, and the leather industry in India, illustrate how redefining the problem from a perspective of resource conservation, and on the basis of resource flow data could point to totally new directions for strategy planning. The case study of the Damodar Valley region amplifies the importance of looking beyond formal industry to solve an environmental problem. It shows that even for globally critical programs, such as climate change program in developing countries, it is just not enough to estimate the emissions from the formal industrial sectors.

An analysis of the metabolic patterns of two rural communities affected by soy expansion in the North of Argentina

The soy expansion model in Argentina generates structural changes in traditional lifestyles that can be associated with different biophysical and socioeconomic impacts. To explore this issue, we apply an innovative method for integrated assessment - the Multi Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) framework - to characterize two communities in the Chaco Region, Province of Formosa, North of Argentina. These communities have recently experienced the expansion of soy production, altering their economic activity, energy consumption patterns, land use, and human time allocation. The integrated characterization presented in the paper illustrates the differences (biophysical, socioeconomic, and historical) between the two communities that can be associated with different responses. The analysis of the factors behind these differences has important policy implications for the sustainable development of local communities in the area.

Financial Development, Financial Fragility, and Growth

This paper studies the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity. On the one hand, the empirical growth literature finds a positive effect of financial depth as measured by, for instance, private domestic credit and liquid liabilities (e.g., Levine, Loayza, and Beck 2000). On the other hand, the banking and currency crisis literature finds that monetary aggregates, such as domestic credit, are among the best predictors of crises and their related economic downturns (e.g., Kaminski and Reinhart 1999). The paper accounts for these contrasting effects based on the distinction between the short- and long-run impacts of financial intermediation. Working with a panel of cross-country and time-series observations, the paper estimates an encompassing model of short- and long-run effects using the Pooled Mean Group estimator developed by Pesaran, Shin, and Smith (1999). The conclusion from this analysis is that a positive long-run relationship between financial intermediation and output growth co-exists with a, mostly, negative short-run relationship. The paper further develops an explanation for these contrasting effects by relating them to recent theoretical models, by linking the estimated short-run effects to measures of financial fragility (namely, banking crises and financial volatility), and by jointly analyzing the effects of financial depth and fragility in classic panel growth regressions.

Firm-Specific Investment, Sticky Prices, and the Taylor Principle

According to the Taylor principle a central bank should adjust the nominal interest rate by more than one-for-one in response to changes in current inflation. Most of the existing literature supports the view that by following this simple recommendation a central bank can avoid being a source of unnecessary fluctuations in economic activity. The present paper shows that this conclusion is not robust with respect to the modelling of capital accumulation. We use our insights to discuss the desirability of alternative interest rate rules. Our results suggest a reinterpretation of monetary policy under Volcker and Greenspan: The empirically plausible characterization of monetary policy can explain the stabilization of macroeconomic outcomes observed in the early eighties for the US economy. The Taylor principle in itself cannot.

Excess Entry, Ambiguity Seeking, and Competence: An Experimental Investigation

Excess entry refers to the high failure rate of new entrepreneurial ventures. Economic explanations suggest 'hit and run' entrants and risk-seeking behavior. A psychological explanation is that people (entrepreneurs) are overconfident in their abilities (Camerer & Lovallo, 1999). Characterizing entry decisions as ambiguous gambles, we alternatively suggest following Heath and Tversky (1991) that people seek ambiguity when the source of uncertainty is related to their competence. Overconfidence, as such, plays no role. This hypothesis is confirmed in an experimental study that also documents the phenomenon of reference group neglect. Finally, we emphasize the utility that people gain from engaging in activities that contribute to a sense of competence. This is an important force in economic activity that deserves more explicit attention.

STRATEGIES TO SURPASS THE VULNERABILITY OF THE SMALL ISLAND STATES WITH FEW RESOURCES: THE CASE OF CAPE VERDE

The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbados’s Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about “Wetlands.” CENTRO DE ESTUDOS AFRICANOS Occasional Papers © CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of “vulnerability” was the inability of the countries to resist economical, ecological and socially to the external shocks and “resilience” as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Aggregate fluctuations and the network structure of intersectoral trade

This paper analyzes the flow of intermediate inputs across sectors by adopting a network perspective on sectoral interactions. I apply these tools to show how fluctuationsin aggregate economic activity can be obtained from independent shocks to individualsectors. First, I characterize the network structure of input trade in the U.S. On thedemand side, a typical sector relies on a small number of key inputs and sectors arehomogeneous in this respect. However, in their role as input-suppliers sectors do differ:many specialized input suppliers coexist alongside general purpose sectors functioningas hubs to the economy. I then develop a model of intersectoral linkages that can reproduce these connectivity features. In a standard multisector setup, I use this modelto provide analytical expressions linking aggregate volatility to the network structureof input trade. I show that the presence of sectoral hubs - by coupling productiondecisions across sectors - leads to fluctuations in aggregates.
