Contribution à la théorie de l'éMergie : application au recyclage / Contribution to the emergy theory : application to recycling

Amponsah, Nana Yaw 23 September 2011 (has links)
Le développement continu d’outils pour mesurer le développement durable a conduit à la théorie éMergétique. L’éMergie d’une ressource ou d’un produit est définie en convertissant toutes les ressources (matières premières) et les entrées d’énergie sous la forme de leurs équivalents énergétiques solaires (solar energy unit seJ), cf Odum (1996, 2000). L'objectif principal de cette thèse est d'adapter la méthode d'analyse éMergétique aux pratiques de recyclage industriel. La principale contribution scientifique de cette étude peut être résumée comme suit: contribution à la théorie éMergétique en temps discret appliquée au recyclage. Sous certaine hypothèses, l’émergie d'un produit recyclé peut être exprimée sous la forme d’une série géométrique. L'éMergétique d'un produit se détériorant, il existe un prix éMergétique au recyclage et une analogie avec l’énoncé de Carnot peut être faite. En conséquence, un nouveau «facteur» est introduit, ce dernier peut être inclus dans les tables d'évaluation éMergétique, pour tenir compte des accroissements de transformité dû aux recyclages multiples. Enfin, l'approche développée est appliquée avec succès à l'utilisation de matériaux de recycle dans un bâtiment basse énergie. / The continuous development of tools to measure sustainability led to the eMergy theory. The Emergy of a resource or product is defined by converting all resource (raw materials) and energy inputs in the form of solar energy equivalents (solar energy unit, seJ), cf Odum (1996, 2000). The main objective of this thesis is to adapt the method of emergy evaluation to industrial recycling practices. The principal scientific contribution from the study can be summarized as: contribution to th eMergy theory in discrete time applied to recycling. Under certain assumptions, the emergy of a recycled product can be expressed in the form of a geometric series. If the emergy of a product deteriorates, there is a cost to the emergy of recycling with similarities to the Carnot principle. As a result, a ‘factor’ is introduced which could be included on emergy evaluation tables to reflect increases in transformity due to multiple recycling. Fi nally, the developed approach is successfully applied to the use of recycle materials in a Low Energy Building.

Diversification des ressources du réseau d’eau non potable parisien : contribution à une gestion durable des ressources en eau / Diversification of the resources of the Parisian water network : contribution to sustainable management of water resources

Trinh, Bich-Thuy 28 September 2017 (has links)
A l’échelle d’une agglomération, réfléchir à une gestion durable de l’eau amène à s’interroger sur les liens entre les usages et les ressources : quelle qualité de l’eau est nécessaire pour quels usages ? Le contexte parisien est un terrain propice pour mener ce type de réflexion, grâce à l’existence d’un RENP, datant de la fin du XIXe siècle. Alimenté par les eaux sommairement traitées de la Seine (20%) et du canal de l’Ourcq (80%), ce réseau sert principalement aux usages municipaux : nettoyage des trottoirs, curage des égouts, arrosage des espaces verts et alimentation des lacs artificiels. Un modèle alternatif de gestion de l’eau à l’échelle parisienne devient aujourd’hui possible grâce à la décision de la Ville de Paris en mars 2012 de maintenir et de réhabiliter son RENP. Cette décision a été confirmée par l’approbation par le Conseil de Paris en septembre 2015 du schéma directeur des usages et du réseau d’eau non potable de Paris, pour la période 2015-2020. L’entreprise publique Eau de Paris, responsable du service de l’eau à Paris, a pour mission de mettre en œuvre les décisions et les orientations de ce schéma directeur. Dans une logique de moindre pression sur la ressource naturelle, une évolution possible de la gestion du RENP est la diversification de ses ressources. Les ressources potentielles considérées sont les eaux d’exhaure, les eaux usées traitées, les eaux de pluie et les eaux de piscine. La recherche vise à étudier la question suivante : Comment et à quelle conditions l’alimentation du RENP peut être gérée de manière durable sur le territoire parisien ? Pour ce faire, on réalise d’abord un état des lieux de la situation actuelle, puis on identifie les ressources potentielles et les enjeux associés. Puis deux approches sont menées. La première approche consiste à définir plusieurs choix de répartition des ressources du RENP, appelés scenarii. Les scénarii sont évalués et comparés grâce à la construction d’indicateurs de performance. La deuxième approche consiste à caractériser les positions des acteurs par rapport à la diversification des ressources du RENP. La caractérisation des positions est réalisée grâce à la conduite d’entretiens semi-directifs. Les résultats des deux approches sont enfin discutés. Les résultats de la recherche permettront de reposer la question du lien entre usages et qualité des eaux requise. Elle permettra de mettre en lumière les freins et les leviers pour la valorisation des ressources alternatives à l’eau potable. Enfin, elle alimentera les réflexions sur le statut même de l’eau potable dans un contexte de gestion durable de la ressource / At the scale of a city, a sustainable water management raises questions about the links between uses and resources: what water quality is needed for what purpose? The Parisian context is a favourable ground for conducting such type of reflection thanks to the existence of a non-potable water network (RENP) dating from the late nineteenth century. The network is currently supplied by summarily filtrated water from the Seine river (20%) and the canal de l’Ourcql (80%). It is mainly used for municipal purposes: Parisian streets and sewers cleaning, water supply of artificial lakes and green areas watering. An alternative model of water management at Parisian scale is today possible thanks to the decision of the City of Paris in March 2012 to maintain and rehabilitate its RENP. This decision has been confirmed by the approval by the Council of Paris in September 2015 of the master plan of the RENP and its uses (“Schéma directeur des usages et du réseau d’eau non potable de Paris”) for the period of 2015-2020. The public company Eau de Paris, responsible for the water service in Paris, is mandated to implement the decisions and orientations of the master plan. In the context of pressure reduction on natural resources, one potential evolution of the RENP management is its resources diversification. The considered potential resources are mine water, treated wastewater, rain water and swimming pool water. The research raises the following question: How and under what conditions can the RENP supply be sustainably managed on the Parisian territory? In order to answer this question, one first carries out a description of the current situation, then one identifies the potential resources and the associated risen questions. Two approaches are proposed afterwards. The first approach involves the definition of several choices of RENP resource repartition, called scenarii. These scenarii are assessed and compared through performance indicators. The second approach consists of the characterization of the actors’ positions regarding the RENP resource diversification. The characterization of the positions is achieved through conducting semi-structured interviews. Results of both approaches are finally discussed.The results of the research will enable to re-examine the question of the relationship between the water uses and the required water quality. It will highlight the brakes and levers for the valorization of alternative resources to drinking water. It will enrich the reflections on the status of drinking water in the context of sustainable water management

Key challenges in the governance of rural water supply: lessons learnt from tanzania

Jiménez Fernández de Palencia, Alejandro 17 May 2010 (has links)
El primer objetivo de esta tesis es la identificación y análisis de aspectos clave para la gobernanza de los servicios de agua rural en países que adolecen de bajos niveles de cobertura, altos índices de pobreza, se encuentran en procesos de descentralización, reciben un importante apoyo de donantes internacionales. Esta situación es común para muchos países de África Sub-sahariana. Por ello, se eligió Tanzania como objeto de estudio. El segundo objetivo de esta tesis ha sido el ensayo de nuevas herramientas y mecanismos institucionales para la mejora de la eficiencia, equidad y sostenibilidad en la provisión de agua en las zonas rurales, con especial énfasis en el nivel de gobierno descentralizado. Para ello, se desarrollaron experiencias piloto así como procesos de investigación-acción. En el capítulo 1 se estudia el papel desempeñado por los diferentes actores internacionales en la financiación del sector del agua en los países en desarrollo durante la década 1995-2004. En el capítulo 2 se analizan los indicadores existentes para el seguimiento del sector del agua a nivel internacional, específicamente los utilizados para valorar el cumplimiento de los Objetivos del Milenio, así como el Índice de Pobreza Hídrica (Water Poverty Index). Se detallan algunos limitantes en cuanto al alcance y metodología de cálculo de estos indicadores, y se proponen las características básicas que los indicadores deben tener para apoyar la toma de decisiones a nivel gubernamental. En el capítulo 3 se presenta una metodología para el desarrollo de indicadores más completos de acceso al agua, basándose en el Mapeo de Puntos de Agua (Water Point Mapping-WPM). La metodología propuesta, denominada Mapeo Mejorado de Puntos de Agua, incluye la medición de parámetros básicos de calidad del agua y estacionalidad de los servicios. La factibilidad y pertinencia de la adopción de esta metodología a nivel nacional se desarrolló satisfactoriamente a modo de experiencia piloto en dos distritos de Tanzania, con una población rural aproximada de 840.000 personas (capítulo 4). En el capítulo 5 se analiza la sostenibilidad de los servicios de agua rural en relación al tipo de tecnología utilizada para el abastecimiento. El análisis se basa en los datos de 6814 puntos de agua, sobre una población equivalente al 15% de la población rural de Tanzania. El capítulo 6 se analiza el proceso de toma de decisiones, desde el nivel central al nivel comunitario, para la asignación de recursos en el sector del agua rural. Los resultados en los 4 distritos estudiados muestran que menos de la mitad de los proyectos asignados se destinan a zonas con baja cobertura de servicios. Las incoherencias entre el diseño y la implementación de los planes nacionales, y la influencia de los poderes políticos locales son los mayores obstáculos para una equitativa distribución de los recursos. El capítulo 7 detalla el caso de investigación-acción ejecutado a nivel de gobierno local entre 2006 y 2009 con el gobierno del distrito de Same, Tanzania. La mejora de la equidad y la sostenibilidad se fomentaron mediante el desarrollo de herramientas de planificación basadas en el WPM y de mecanismos institucionales para el apoyo a largo plazo a los sistemas de agua rurales. En el capítulo 8 se detallan las conclusiones generales y líneas de investigación futuras. La resolución de los desafíos principales encontrados implican la adopción de paradigmas diferentes: i) la aceptación del agua rural como un servicio responsabilidad del gobierno y no de las comunidades; ii) las actuaciones deben decidirse en función de las necesidades de las comunidades, y no de su capacidad de demanda, iii) el establecimiento de sistemas de información internos que partan desde el nivel local y estén adaptados a las capacidades de actualización disponibles, iv) el desarrollo de mecanismos para la orientación y el seguimiento cercano de los procesos de toma de decisión a nivel local / The first objective of this thesis is the identification and analysis of key issues in the governance of rural water services in countries that suffer from a lack of rural water access, high levels of poverty, are under decentralization processes and receive significant donor support. This is a common situation for many Sub-Saharan countries. To address the relevant aspects, Tanzania was taken as a case study and was analyzed in depth. The second objective was to test tools and propose institutional arrangements at that can improve efficiency, equity and sustainability in the provision of water for the rural areas, with special focus at the local government level. This was made through pilot experiences and an action research case study. In Chapter 1 we analyse the role played by the international actors in the financing of the water sector of developing countries, in the period 1995-2004. In Chapter 2 we study existing indicators for international monitoring, specifically the ones used by the Joint Monitoring Programme for the monitoring of the MDGs, as well as the Water Poverty Index (WPI). Some drawbacks are found the indicators’ scope and methodology, which prevents them from being used as policy drivers at national level. The chapter concludes by proposing the main characteristics that those indicators must entail to be useful for governmental decision making. In Chapter 3, a methodology to define water access indicators, based on GIS-based Water Point Mapping (WPM) is proposed. The methodology, named Enhanced Water Point Mapping (EWPM), includes the measurement of basic parameters of quality of water and seasonality of the service. The feasibility and relevance of adopting this methodology at national level was tested with success in two districts in Tanzania, covering a rural population of approximately 840,000 people, as described in Chapter 4. In chapter 5, we analyze the sustainability of systems over time, and the relation between sustainability and technology; this chapter is based on the study of 6814 water points, covering 15% of the rural population in the country. Chapter 6 analyses the aspects affecting financial resource allocation for rural water in Tanzania at all levels, from central government to village level. Results in four districts studied showed that less than half of allocated projects go to underserved areas. Incoherencies between the design and the implementation of the plans and political influences at local level are highlighted as major obstacles to the effective, equitable allocation of resources. In chapter 7, we describe an action research process that was carried out at local government level, together with Same District Council, between 2006 and 2009. The improvement of equity and sustainability was supported through the development of EWPM based planning tools and new institutional arrangements for the long-term support of community managed water supplies. In Chapter 8 the overall conclusions and future research lines are presented. We propose some new paradigms in the sector: i) rural water supply must be considered as a service, with government and not communities as main duty bearers; ii) the adoption of a needs-based approach to projects planning at community level, instead of the current demand driven, iii) the establishment of bottom-up internal information systems adapted to available updating capacities and iv) the development of mechanisms for the guidance and close monitoring of local government decision-making.

Un instrument de la planification traditionnelle urbaine et durable : le 'Hawch' hérité dans le paysage méditerranéen : le cas de Beyrouth / An instrument of sustainable and traditional urban planning : the 'Hawchs' in the Mediterranean landscape : the case of Beirut

Zeidan, Nina 17 December 2013 (has links)
Le “Hawch” forme à Beyrouth un élément de planification urbaine héritée. Il est un ensemble d'habitat traditionnel dense, entouré par une enceinte à mur aveugle et accessible à partir d'un « Zoukak »-ruelle étroite de desserte-. Il renferme en son intérieur une vie communautaire identitaire de la société libanaise autour d'un espace végétal qui le structure. De par sa situation géographique périphérique au centre-ville de Beyrouth en reconstruction il subit des tensions. La première est une tension extérieure : premièrement économique qui est due aux spéculations foncières et immobilières, deuxièmement urbaine en termes de densification et d'étalement urbain. La deuxième tension est intérieure venant en premier lieu du repli communautaire que présente sa société face à la tendance beyrouthine à l'individualisation et à l'occidentalisation et en deuxième lieu de la « compétence du propriétaire » de modifier le spatial aux dépens de l'équilibre écologique du microclimat du « Hawch ». Le « Hawch » se présente comme une réponse aux discours sur la politique des villes de nos jours. Ses trois composantes intrinsèques le social, le spatial et l'environnemental paysager correspondant aux trois piliers du développement durable répondent aux problématiques de la ville de Beyrouth moderne. Les potentialités du vivre ensemble de sa dimension sociale, l'écologie spatiale urbaine de sa dimension spatiale et le microclimat comme dimension environnementale paysagère le prédisposent à perdurer dans la ville de Beyrouth contemporaine sous forme de « Hawch » revisité que nous appellerons le « Néo-Hawch ». / The "Hawch" is an inherited element in Beirut urban planning. It is a dense grouping of traditional habitat, surrounded by an enclosure wall and accessible from a "Zoukak" –a narrow service street-. It contains in its interior a community life identical to that of Lebanese society around a structuring green space. By its peripheral location to Beirut's Downtown that's being rebuilt, the “Hawch” is subject to stress conditions. The first is an external pressure: first, in an economic order that is due to land and property speculation, the second in terms of urban densification and sprawl. The second is an internal tension coming first by the community fallback presented by its inner society facing Beirut's trend towards individualization and Westernization and secondly the "competence of the owner" to modify the space at the expense of the "Hawch"'s ecological microclimate balance. The "Hawch" comes as a response to the discourse on today's urban policy. Three intrinsic components: social, spatial and environmental landscape corresponding to the three sustainable development pillars meet the challenges of the modern city of Beirut. The potentialities of living together in the social dimension, urban spatial ecology of the spatial dimension and the environmental dimension microclimate as landscape predisposes it to persist in the contemporary city of Beirut as "Hawch" Revisited that we call the "Neo-Hawch ".

Organizing the 'Unorganized' Indian Craf Industry - Systemic Issues in Scarling-up Social Impact to Produce Craft-based 'Sustainable' Fashion

Chirravuru, Laya 30 June 2022 (has links)
from the content: „The global discourse of sustainability critically challenges fashion as a sys-tem today and encourages organic ways of making as one of the primary mediums to address the three pillars of sustainability. In this regard, crafts and hand-making play key roles in achieving India’s sustainable de-velopment goals, suitable to its socio-economic context. The growing awareness of this subject points to an advantage the country has in its generational textile knowledge, which presents the opportunity to create employment for the vast communities of artisans. ...

Will green banking unlock a sustainibility transition towards a low-carbon economy? : The perspective of a member-owned bank in Sweden / Kommer gröna banker möjliggöra en hållbarhetsövergång till en koldioxidsnål ekonomi? : En svensk medlemsägd banks perspektiv

Solheim, Ulrika January 2019 (has links)
In the climate change discussion, there is a broad consensus about the importance of support from the financial industry when it comes to supporting changes towards a more sustainable society. However, investments in the society supporting a transition towards a low-carbon economy are still waiting to become unlocked. This thesis aims to provide an understanding of a possible sustainability transition towards a low-carbon economy within the Swedish financial industry. To fully understand a possible change, this study has investigated the dynamics of the financial industry from the perspective of a member-owned bank in Sweden. Hence this study seeks to explore a fundamental and comprehensive change, the theoretical framework of socio-technical transition and the multi-level perspective is used. This contributes to a vast mapping of the financial industry and a better understanding of the dynamics of social change and innovation, such as a low-carbon economy transition. To gain in-depth knowledge, a case study was performed. Both qualitative and quantitative data was collected through semi-structured interviews and data from the case company’s customer database. The carbon footprint of the case company bank’s loan portfolio was calculated and analysed through a sensitivity analysis. This was done in the aim to gain deeper insights about how actions from a bank could contribute to a low-carbon economy. The empirical findings in this thesis showed that a bank does have the ability and power to contribute to a lower carbon footprint in a bureaucratic and stable regime as the financial industry. However, this responsibility could be hard to put at a single actor. As the financial industry has a strong carbon lock-in, the approach has to be long-term. The actions that could enable a sustainability transition within the financial industry seems to be a collection of many different transition pathways. By remaining the landscape pressure and the development of niche innovations, a long-term sustainability transition seems imaginable. By collecting the forces of regulatory work along with collaboration among incumbent actors and increasing development of new low-carbon financial products, there is positive movement. With patience and an attitude change, the financial industry can see a sustainability transition in the horizon. / I diskussionen om klimatförändringar finns det en enighet om vikten av stöd från finansbranschen när det gäller förändringar mot ett mer hållbart samhälle. Investeringar i samhället som stöder en övergång till en koldioxidsnål ekonomi väntar dock fortfarande på att slå igenom. Denna uppsats har som syfte att förstå en möjlig hållbarhetsövergång till en koldioxidsnål ekonomi inom den svenska finansbranschen. För att förstå en möjlig förändring har denna undersökning granskat finansbranschens dynamik utifrån en svensk medlemsägd banks perspektiv. Då denna uppsats strävar efter att utforska en grundläggande och omfattande förändring, så har det teoretiska ramverket för socio-teknisk övergång och multi-nivåperspektivet används. Detta bidrar till en omfattande kartläggning av finansbranschen samt en bättre förståelse för dynamiken i socialförändring och innovation, så som en övergång till en mer koldioxidsnål ekonomi. För att få fördjupad kunskap inom ämnet så har en case-studie utförts. Både kvalitativa och kvantitativa data har samlats in genom halvstrukturerade intervjuer och data från case-företagetskunddatabas. Koldioxidavtrycket i case-företagets utlåningsportfölj beräknades och analyserades genom en känslighetsanalys. Detta gjordes i syfte att få djupare insikter om hur åtgärder från enbank skulle kunna bidra till en koldioxidsnål ekonomi. De empiriska resultaten i denna studie visade att en bank har förmågan och kraften att bidra till ett lägre koldioxidavtryck i en byråkratisk och stabil regim som finansindustrin. Detta ansvar kan dock vara svårt att lägga på en enskild aktör. Eftersom finansbranschen idag har investeringar i koldioxidtunga aktiviteter måste tillvägagångssättet vara långsiktigt. De åtgärder som kan möjliggöra en hållbar övergång inom finansbranschen verkar vara en samling av många olika övergångsbanor. Genom att ha fortsatttryck från landskaps-nivån och en fortsatt utveckling av nisch-innovationer verkar en långsiktig hållbarhetsövergång tänkbar. Genom en enad kraft, samarbete mellan etablerade aktörer och ökad utveckling av nya finansiella produkter med låg koldioxidutsläpp, verkar en förändring möjlig. Med tålamod och en attitydförändring kan finansindustrin se en hållbarhetsövergång i horisonten.
