The concept and logic of the "smile curve" in the context of global value chains has been widely used and discussed at the individual firm level, but rarely identified and investigated at the country and industry levels by using real data. This paper proposes an idea, based on an inter-country input-output model, to consistently measure both the strength and length of linkages between producers and consumers along global value chains. This idea allows for better identification and mapping of smile curves for countries and industries according to their positions and degrees of participation in a given conceptual value chain. Using the 1995-2011 World Input-Output Tables, several conceptual value chains are investigated, including exports of electrical and optical equipment from China and Mexico and exports of automobiles from Japan and Germany. The identified smile curves provide a very intuitive and visual image, which can significantly improve our understanding of the roles played by different countries and industries in global value chains. Further, the smile curves help identify the benefits gained by these countries and industries through their participation in global trade.

Studies on the rise of global value chains (GVCs) have attracted a great deal of interest in the recent economics literature. However, due to statistical and methodological challenges, most existing research ignores domestic regional heterogeneity in assessing the impact of joining GVCs. GVCs are supported not only directly by domestic regions that export goods and services to the world market, but also indirectly by other domestic regions that provide parts, components, and intermediate services to final exporting regions. To better understand the nature of a country's position and degree of participation in GVCs, we need to fully examine the role of individual domestic regions. Understanding the domestic components of GVCs is especially important for larger economies such as China, the US, India and Japan, where there may be large variations in economic scale, geography of manufacturing, and development stages at the domestic regional level. This paper proposes a new framework for measuring domestic linkages to global value chains. This framework measures domestic linkages by endogenously embedding a target country's (e.g. China and Japan) domestic interregional input–output tables into the OECD inter-country input–output model. Using this framework, we can more clearly understand how global production is fragmented and extended internationally and domestically.

Supply chain management works to bring the supplier, the distributor, and the customer into one cohesive process. The Supply Chain Council defined supply chain as ‘Supply Chain: The flow and transformation of raw materials into products from suppliers through production and distribution facilities to the ultimate consumer., and then Sunil Chopra and Meindl, (2001) have define Supply chain management as ‘Supply Chain Management involves the flows between and among stages in a supply chain to maximize total profitability.’ After 1950, supply chain management got a boost with the production and manufacturing sector getting highest attention. The inventory became the responsibility of the marketing, accounting and production areas. Order processing was part of accounting and sales. Supply chain management became one of the most powerful engines of business transformation. It is the one area where operational efficiency can be gained. It reduces organizations costs and enhances customer service. With the liberalization of world trade, globalization, and emergence of the new markets, many organizations have customers and competitions throughout the world, either directly or indirectly. Business communities are aware that global competitiveness is the key to the success of a business. Competitiveness is ability to produce, distribute and provide products and services for the open market in competition with others. The supply chain, a critical link between supplier, producer and customer is emerged now as an essential business process and a strategic lever, potential value contributor a differentiator for the success of any business. Supply chain management is the management of all internal and external processes or functions to satisfy a customer’s order (from raw materials through conversion and manufacture through logistics delivery.). Goods-either in raw form or processed, whole sale or retailed distribution, business or technology services, in everyday life- in the business or household- directly or indirectly supply chain is ubiquitously associated in expanding socio-economic development. Supply chain growth competitive performance and supporting strong growth impulse at micro as well as micro economic levels. Keeping the India vision at the core of the objective, the role of supply chain is to take up social economic challenges, improve competitive advantages, develop strategies, built capabilities, enhance value propositions, adapt right technology, collaborate with stakeholders and deliver environmentally sustainable outcomes with minimum resources.

In arid countries worldwide, social conflicts between irrigation-based human development and the conservation of aquatic ecosystems are widespread and attract many public debates. This research focuses on the analysis of water and agricultural policies aimed at conserving groundwater resources and maintaining rurallivelihoods in a basin in Spain's central arid region. Intensive groundwater mining for irrigation has caused overexploitation of the basin's large aquifer, the degradation of reputed wetlands and has given rise to notable social conflicts over the years. With the aim of tackling the multifaceted socio-ecological interactions of complex water systems, the methodology used in this study consists in a novel integration into a common platform of an economic optimization model and a hydrology model WEAP (Water Evaluation And Planning system). This robust tool is used to analyze the spatial and temporal effects of different water and agricultural policies under different climate scenarios. It permits the prediction of different climate and policy outcomes across farm types (water stress impacts and adaptation), at basin's level (aquifer recovery), and along the policies’ implementation horizon (short and long run). Results show that the region's current quota-based water policies may contribute to reduce water consumption in the farms but will not be able to recover the aquifer and will inflict income losses to the rural communities. This situation would worsen in case of drought. Economies of scale and technology are evidenced as larger farms with cropping diversification and those equipped with modern irrigation will better adapt to water stress conditions. However, the long-term sustainability of the aquifer and the maintenance of rurallivelihoods will be attained only if additional policy measures are put in place such as the control of illegal abstractions and the establishing of a water bank. Within the policy domain, the research contributes to the new sustainable development strategy of the EU by concluding that, in water-scarce regions, effective integration of water and agricultural policies is essential for achieving the water protection objectives of the EU policies. Therefore, the design and enforcement of well-balanced region-specific polices is a major task faced by policy makers for achieving successful water management that will ensure nature protection and human development at tolerable social costs. From a methodological perspective, this research initiative contributes to better address hydrological questions as well as economic and social issues in complex water and human systems. Its integrated vision provides a valuable illustration to inform water policy and management decisions within contexts of water-related conflicts worldwide.

Las dinámicas de reorganización de la producción y las transformaciones económicas determinaron la crisis de gran parte de las regiones industriales de Europa y Estados Unidos en las últimas décadas del siglo XX. Ante la persistencia e intensidad del declive de muchas de ellas, cabe preguntarse, ¿existen futuros para la ciudad industrial? O, en otras palabras, ¿es el declive un proceso irreversible? La incidencia dispar del declive así como la gradual regeneración de algunas regiones industriales en los últimos años parece apuntar hacia cierta capacidad de respuesta local ante unas dinámicas de escala global. Las múltiples trayectorias de las regiones de base industrial tan sólo parecen poder explicarse desde su singularidad. La presente tesis doctoral tiene por objeto analizar las posibilidades de orientar los procesos de deterioro urbano de las regiones industriales y examinar la capacidad de la planificación de intervenir sobre ellos a través de dos estudios de caso, El modo de abordar el análisis, estudiar la ciudad en evolución, debería proporcionar una mejor comprensión de las repercusiones del modelo de crecimiento de cada ciudad sobre su posterior declive y resaltar la influencia de las decisiones políticas y espaciales de cada etapa en el desarrollo futuro del territorio. Analizar la evolución de dos regiones industriales extremadamente diferentes dará la oportunidad de investigar, en primer lugar, uno de los casos paradigmáticos de deterioro urbano, Detroit y, tras haberse interrogado sobre las causas específicas de la persistencia y duración de su declive, estudiar la evolución urbana de la región de Nantes – Saint-Nazaire para comprender la singularidad de su regeneración tras años de estancamiento. El análisis de estos territorios debería permitir progresar en el conocimiento de los procesos de declive, comparar las diferentes estrategias y modelos urbanos, comprender las diferencias entre ellos e interrogarnos sobre la posibilidad de orientar los procesos de deterioro urbano. Las respuestas de este análisis quizás nos ayuden a afirmar la existencia de futuros múltiples para la ciudad industrial. Global dynamics such as economic transformations and reorganizations of production led to the crisis of most industrial cities in Europe and the U.S in the last decades of the 20th century. Most of them have suffered or are still suffering the consequences of urban decay and shrinkage. Given the severity and persistence of some of these processes, a significant question may be raised: are there alternative futures for former industrial cities? Or is urban decay an irreversible process? Nevertheless, the diverse evolution of these cities, as well as the gradual restructuring of some of them in recent years, seem to point toward the relevance of local response to these global dynamics. The different paths of development of industrial cities since 1970s may only be explained by their singularity and specific local conditions. This research aims to examine possibilities to guide urban decline and shrinkage in former industrial regions and to analyze the ability of urban planning to intervene in these processes through two case studies. The method of research, exploring cities in evolution, should provide a greater understanding of the effects of different modes of development during the city’s heyday on its subsequent shrinkage. Likewise, it should highlight the influence of each period’s local decisions on the future trajectory of the city. The evolutive analysis of two extremely different industrial regions will give us, first, the opportunity to study a paradigm of urban decay, Detroit, by exploring over time the specific causes of its decline’s prevalence. In the second place, we will be able to study Nantes - Saint-Nazaire region, examining the distinctiveness of its recent restructuring after years of shrinkage and stagnation. Through these examples, we would be able to analyze the consequences of decision-making on the evolution of each city. It should also let us compare diverse strategies and enable us to question the ability of planning to tackle decay. The conclusions of the analysis may help us to assert the existence of alternative futures for industrial cities.

Population growth, economic globalization, improving living standards and urbanization are causing important changes in the global food system and modifying the dietary habits in many parts of the world (Molden, 2007; Godfray et al., 2010). The nutritional transition (linked to the development of countries and the increasing wealth of its population) implies a shift away from traditional staple food such as roots and tuber vegetables and a rise in consumption of meat and milk products, refined and processed foods, as well as sugars, oils and fats (Ambler-Edwards et al., 2009). The contemporary food system puts significant pressure on natural resources, especially on land and water, because the growing food demand pushes the agricultural frontier beyond, causing large impacts on ecosystems (Ambler-Edwards et al. 2009: 11-18). Also, the trend towards richer diets in animal proteins and processed food adds further pressure on the environment, since it requires larger amount of water and land to be produced (Allan, 2011; Mekonnen and Hoekstra, 2012).

A pesar de los importantes avances en la reducción del hambre, la seguridad alimentaria continúa siendo un reto de dimensión internacional. La seguridad alimentaria es un concepto amplio y multidimensional, cuyo análisis abarca distintas escalas y horizontes temporales. Dada su complejidad, la identificación de las causas de la inseguridad alimentaria y la priorización de las medias para abordarlas, son dos cuestiones que suscitan un intenso debate en la actualidad. El objetivo de esta tesis es evaluar el impacto de la globalización y el crecimiento económico en la seguridad alimentaria en los países en desarrollo, desde una perspectiva macro y un horizonte temporal a largo plazo. La influencia de la globalización se aborda de una manera secuencial. En primer lugar, se analiza la relación entre la inversión público-privada en infraestructuras y las exportaciones agrarias. A continuación, se estudia el impacto de las exportaciones agrarias en los indicadores de seguridad alimentaria. El estudio del impacto del crecimiento económico aborda los cambios paralelos en la distribución de la renta, y cómo la inequidad influye en el comportamiento de la seguridad alimentaria nacional. Además, se analiza en qué medida el crecimiento económico contribuye a acelerar el proceso de mejora de la seguridad alimentaria. Con el fin de conseguir los objetivos mencionados, se llevan a cabo varios análisis econométricos basados en datos de panel, en el que se combinan datos de corte transversal de 52 países y datos temporales comprendidos en el periodo 1991-2012. Se analizan tanto variables en niveles como variables en tasas de cambio anual. Se aplican los modelos de estimación de efectos variables y efectos fijos, ambos en niveles y en primeras diferencias. La tesis incluye cuatro tipos de modelos econométricos, cada uno de ellos con sus correspondientes pruebas de robustez y especificaciones. Los resultados matizan la importancia de la globalización y el crecimiento económico como mecanismos de mejora de la seguridad alimentaria en los países en desarrollo. Se obtienen dos conclusiones relativas a la globalización. En primer lugar, los resultados sugieren que la promoción de las inversiones privadas en infraestructuras contribuye a aumentar las exportaciones agrarias. En segundo lugar, se observa que las exportaciones agrarias pueden tener un impacto negativo en los indicadores de seguridad alimentaria. La combinación de estas dos conclusiones sugiere que la apertura comercial y financiera no contribuye por sí misma a la mejora de la seguridad alimentaria en los países en desarrollo. La apertura internacional de los países en desarrollo ha de ir acompañada de políticas e inversiones que desarrollen sectores productivos de alto valor añadido, que fortalezcan la economía nacional y reduzcan su dependencia exterior. En relación al crecimiento económico, a pesar del incuestionable hecho de que el crecimiento económico es una condición necesaria para reducir los niveles de subnutrición, no es una condición suficiente. Se han identificado tres estrategias adicionales que han de acompañar al crecimiento económico con el fin de intensificar su impacto positivo sobre la subnutrición. Primero, es necesario que el crecimiento económico sea acompañado de una distribución más equitativa de los ingresos. Segundo, el crecimiento económico ha de reflejarse en un aumento de inversiones en salud, agua y saneamiento y educación. Se observa que, incluso en ausencia de crecimiento económico, mejoras en el acceso a agua potable contribuyen a reducir los niveles de población subnutrida. Tercero, el crecimiento económico sostenible en el largo plazo parece tener un mayor impacto positivo sobre la seguridad alimentaria que el crecimiento económico más volátil o inestable en el corto plazo. La estabilidad macroeconómica se identifica como una condición necesaria para alcanzar una mayor mejora en la seguridad alimentaria, incluso habiéndose mejorado la equidad en la distribución de los ingresos. Por último, la tesis encuentra que los países en desarrollo analizados han experimentado diferentes trayectorias no lineales en su proceso de mejora de sus niveles de subnutrición. Los resultados sugieren que un mayor nivel inicial de subnutrición y el crecimiento económico son responsables de una respuesta más rápida al reto de la mejora de la seguridad alimentaria. ABSTRACT Despite the significant reductions of hunger, food security still remains a global challenge. Food security is a wide concept that embraces multiple dimensions, and has spatial-temporal scales. Because of its complexity, the identification of the drivers underpinning food insecurity and the prioritization of measures to address them are a subject of intensive debate. This thesis attempts to assess the impact of globalization and economic growth on food security in developing countries with a macro level scale (country) and using a long-term approach. The influence of globalization is addressed in a sequential way. First, the impact of public-private investment in infrastructure on agricultural exports in developing countries is analyzed. Secondly, an assessment is conducted to determine the impact of agricultural exports on food security indicators. The impact of economic growth focuses on the parallel changes in income inequality and how the income distribution influences countries' food security performance. Furthermore, the thesis analyzes to what extent economic growth helps accelerating food security improvements. To address the above mentioned goals, various econometric models are formulated. Models use panel data procedures combining cross-sectional data of 52 countries and time series data from 1991 to 2012. Yearly data are expressed both in levels and in changes. The estimation models applied are random effects estimation and fixed effects estimations, both in levels and in first differences. The thesis includes four families of econometric models, each with its own set of robustness checks and specifications. The results qualify the relevance of globalization and economic growth as enabling mechanisms for improving food security in developing countries. Concerning globalization, two main conclusions can be drawn. First, results showed that enhancing foreign private investment in infrastructures contributes to increase agricultural exports. Second, agricultural exports appear to have a negative impact on national food security indicators. These two conclusions suggest that trade and financial openness per se do not contribute directly to improve food security in development countries. Both measures should be accompanied by investments and policies to support the development of national high value productive sectors, to strengthen the domestic economy and reduce its external dependency. Referring to economic growth, despite the unquestionable fact that income growth is a pre-requisite for reducing undernourishment, results suggest that it is a necessary but not a sufficient condition. Three additional strategies should accompany economic growth to intensifying its impact on food security. Firstly, it is necessary that income growth should be accompanied by a better distribution of income. Secondly, income growth needs to be followed by investments and policies in health, sanitation and education to improve food security. Even if economic growth falters, sustained improvements in the access to drinking water may still give rise to reductions in the percentage of undernourished people. And thirdly, long-term economic growth appears to have a greater impact on reducing hunger than growth regimes that combine periods of growth peaks followed by troughs. Macroeconomic stability is a necessary condition for accelerating food security. Finally, the thesis finds that the developing countries analyzed have experienced different non-linear paths toward improving food security. Results also show that a higher initial level of undernourishment and economic growth result in a faster response for improving food security.

Projections for world food production and prices play a crucial role to evaluate and tackle future food security challenges. Understanding how these projections will be affected by climate change is the main objective of this study. By means of a bio-economic approach we assess the economic impacts of climate change on agrifood markets, providing both a global analysis and a regionalised evaluation within the EU. To account for uncertainty, we analyse the IPCC emission scenario A1B for the 2030 horizon under several simulation scenarios that differ in (1) the climate projection, from HadleyCM3 (warm) or ECHAM5 (mild) global circulation models; and (2) the influence of CO2 effects. Results of this study indicate that agrifood market projections to 2030 are very sensitive to climate change uncertainties and, in particular to the magnitude of the carbon fertilization effect.

The agricultural sector could be one of the most vulnerable economic sectors to the impacts of climate change in the coming decades. Climate change impacts are related to changes in the growth period, extreme weather events, and changes in temperature and recipitation patterns, among others. All of these impacts may have significant consequences on agricultural production(Bates, et al.2008. A main issue regarding climate change impacts is related to the uncertainty associated with their occurrence. Climate change impacts can bestimated with simulation models based on several assumptions, among which the future patterns of emissions of greenhouse g asses are quite likely the most relevant, driving the development of future scenarios, i.e. plausible visions of how the future may unfold. Those scenarios are developed as storylines associated with different assumptions about climate and socioeconomic conditions and emissions, with reference figures, such as demographic projections, average global temperatures, etc.(Intergovernmental Panel on Climate Change 2000). Within this context, climate change impact assessment is forced to consider multiple and interconnected sources of uncertainty in order to produce valuable information for policymakers.

The current crisis, with its particularly severe configuration in Southern European countries, provides an opportunity to probe the interrelation of economic crunches and the production of space, and also to imagine potential paths of sociospatial emancipation from the dictates of global markets. This introductory chapter offers a preliminary interpretive framework exploring the fundamental role of urban and territorial restructuring in the formation, management and resolution of capitalist crises and, conversely, periods of crisis as key stages in the history of urbanization. I will begin by contextualizing the 2007-8 economic slump, the subsequent global recession and its uneven impact on states and cities in the longue durée of capitalist productions of space, studying the transformation of spatial configurations in previous episodes of economic stagnation. This broader perspective will then be used to analyze currently emerging formations of austerity urbanism, showing how the practices of crisis management incorporate a strategy for economic and institutional restructuring that eventually impacts on urban policy, and indeed in the production of urban space itself.

Los efectos del cambio global sobre los bosques son una de las grandes preocupaciones de la sociedad del siglo XXI. Algunas de sus posibles consecuencias como son los efectos en la producción, la sostenibilidad, la pérdida de biodiversidad o cambios en la distribución y ensamblaje de especies forestales pueden tener grandes repercusiones sociales, ecológicas y económicas. La detección y seguimiento de estos efectos constituyen uno de los retos a los que se enfrentan en la actualidad científicos y gestores forestales. En base a la comparación de series históricas del Inventario Forestal Nacional Español (IFN), esta tesis trata de arrojar luz sobre algunos de los impactos que los cambios socioeconómicos y ambientales de las últimas décadas han generado sobre nuestros bosques. En primer lugar, esta tesis presenta una innovadora metodología con base geoestadística que permite la comparación de diferentes ciclos de inventario sin importar los diferentes métodos de muestreo empleados en cada uno de ellos (Capítulo 3). Esta metodología permite analizar cambios en la dinámica y distribución espacial de especies forestales en diferentes gradientes geográficos. Mediante su aplicación, se constatarán y cuantificarán algunas de las primeras evidencias de cambio en la distribución altitudinal y latitudinal de diferentes especies forestales ibéricas, que junto al estudio de su dinámica poblacional y tasas demográficas, ayudarán a testar algunas hipótesis biogeográficas en un escenario de cambio global en zonas de especial vulnerabilidad (Capítulos 3, 4 y 5). Por último, mediante la comparación de ciclos de parcelas permanentes del IFN se ahondará en el conocimiento de la evolución en las últimas décadas de especies invasoras en los ecosistemas forestales del cuadrante noroccidental ibérico, uno de los más afectados por la invasión de esta flora (Capítulo 6). ABSTRACT The effects of global change on forests are one of the major concerns of the XXI century. Some of the potential impacts of global change on forest growth, productivity, biodiversity or changes in species assembly and spatial distribution may have great ecological and economic consequences. The detection and monitoring of these effects are some of the major challenges that scientists and forest managers face nowadays. Based on the comparison of historical series of the Spanish National Forest Inventory (NFI), this thesis tries to shed some light on some of the impacts driven by recent socio-economic and environmental changes on our forest ecosystems. Firstly, this thesis presents an innovative methodology based on geostatistical techniques that allows the comparison of different NFI cycles regardless of the different sampling methods used in each of them (Chapter 3). This methodology, in conjunction with other statistical techniques, allows to analyze changes in the spatial distribution and population dynamics of forest species along different geographic gradients. By its application, this thesis presents some of the first evidences of changes in species distribution along different geographical gradients in the Iberian Peninsula. The analysis of these findings, of species population dynamics and demographic rates will help to test some biogeographical hypothesis on forests under climate change scenarios in areas of particular vulnerability (Chapters 3, 4 and 5). Finally, by comparing NFI cycles with permanent plots, this thesis increases our knowledge about the patterns and processes associated with the recent evolution of invasive species in the forest ecosystems of North-western Iberia, one of the areas most affected by the invasion of allien species at national scale (Chapter 6).

Los retos y oportunidades a los que se enfrentan las organizaciones y administraciones de las primeras décadas del siglo XXI se caracterizan por una serie de fuerzas perturbadoras como la globalización, el avance de las tecnologías emergentes y el desequilibrio económico, que están actuando como impulsores de la transformación del mercado. La acción conjunta de estos factores está obligando a todas las empresas industriales a tener que trabajar con mayores y más exigentes niveles de productividad planteándose continuamente como mejorar y lograr satisfacer los requerimientos de los clientes. De esta situación surge la necesidad de volver a plantearse de nuevo ¿quién es el cliente?, ¿qué valora el cliente? y ¿cómo se pueden generan beneficios sostenibles? La aplicación de esta reflexión a la industria naval militar marca los objetivos a los que esta tesis doctoral busca dar respuesta. El primer objetivo, de carácter general, consiste en la definición de un modelo de negocio sostenible para la industria naval militar del 2025 que se adapte a los requisitos del cliente y al nuevo escenario político, económico, social, tecnológico y ambiental que rodea esta industria. El segundo objetivo, consecuencia del modelo general, trata de desarrollar una metodología para ejecutar programas de apoyo al ciclo de vida del “buque militar”. La investigación se estructura en cuatro partes: en la primera se justifica, por un lado, la necesidad del cambio de modelo y por otro se identifican los factores estructurantes para la definición del modelo. La segunda parte revisa la literatura existente sobre uno de los aspectos básicos para el nuevo modelo, el concepto Producto-Servicio. La tercera parte se centra totalmente en la industria naval militar estudiando los aspectos concretos del sector y, en base al trabajo de campo realizado, se identifican los puntos que más valoran las Marinas de Guerra y como estas gestionan al buque militar durante todo su ciclo de vida. Por último se presentan los principios del modelo propuesto y se desarrollan los pilares básicos para la ejecución de proyectos de Apoyo al Ciclo de Vida (ACV). Como resultado de la investigación, el modelo propuesto para la industria naval militar se fundamenta en once principios: 1. El buque militar (producto de alto valor añadido) debe ser diseñado y construido en un astillero del país que desarrolla el programa de defensa. 2. El diseño tiene que estar orientado al valor para el cliente, es decir, se tiene que diseñar el buque militar para que cumpla su misión, eficaz y eficientemente, durante toda su vida operativa, asegurando la seguridad del buque y de las personas y protegiendo el medio ambiente de acuerdo con las regulaciones vigentes. 3. La empresa debe suministrar soluciones integrales de apoyo al ciclo de vida al producto. 4. Desarrollar y mantener las capacidades de integración de sistemas complejos para todo el ciclo de vida del buque militar. 5. Incorporar las tecnologías digitales al producto, a los procesos, a las personas y al propio modelo de negocio. 6. Desarrollar planes de actuación con el cliente domestico a largo plazo. Estos planes tienen que estar basados en tres premisas: (i) deben incluir el ciclo de vida completo, desde la fase de investigación y desarrollo hasta la retirada del buque del servicio; (ii) la demanda debe ser sofisticada, es decir las exigencias del cliente, tanto desde la óptica de producto como de eficiencia, “tiran” del contratista y (iii) permitir el mantenimiento del nivel tecnológico y de las capacidades industriales de la compañía a futuro y posicionarla para que pueda competir en el mercado de exportación. 7. Impulsar el sector militar de exportación mediante una mayor actividad comercial a nivel internacional. 8. Fomentar la multilocalización ya que representa una oportunidad de crecimiento y favorece la exportación posibilitando el suministro de soluciones integrales en el país destino. 9. Reforzar la diplomacia institucional como palanca para la exportación. 10. Potenciar el liderazgo tecnológico tanto en producto como en procesos con políticas activas de I + D+ i. 11. Reforzar la capacidad de financiación con soluciones innovadoras. El segundo objetivo de esta tesis se centra en el desarrollo de soluciones integrales de Apoyo al Ciclo de Vida (ACV). La metodología planteada trata de minimizar la brecha entre capacidades y necesidades a lo largo de la vida operativa del barco. Es decir, el objetivo principal de los programas de ACV es que la unidad conserve durante toda su vida operativa, en términos relativos a las tecnologías existentes, las capacidades equivalentes a las que tendrá cuando entre en servicio. Los ejes de actuación para conseguir que un programa de Apoyo al Ciclo de Vida cumpla su objetivo son: el diseño orientado al valor, la ingeniería de Apoyo al Ciclo de Vida, los proyectos de refresco de tecnología, el mantenimiento Inteligente y los contratos basados en prestaciones. ABSTRACT On the first decades of the 21st century, organizations and administrations face challenges and come across opportunities threatened by a number of disruptive forces such as globalization, the ever-changing emerging technologies and the economic imbalances acting as drivers of the market transformation. This combination of factors is forcing all industrial companies to have more and higher demanding productivity levels, while bearing always in mind how to improve and meet the customer’s requirements. In this situation, we need to question ourselves again: Who is the customer? What does the customer value? And how can we deliver sustainable economic benefits? Considering this matter in a military naval industry framework sets the goals that this thesis intends to achieve. The first general goal is the definition of a new sustainable business model for the 2025 naval industry, adapted to the customer requirements and the new political, economic, social, technological and environmental scenario. And the second goal that arises as a consequence of the general model develops a methodology to implement “warship” through life support programs. The research is divided in four parts: the first one justifies, on the one hand, the need to change the existing model and, on the other, identifies the model structural factors. On the second part, current literature regarding one of the key issues on the new model (the Product-Service concept) is reviewed. Based on field research, the third part focuses entirely on military shipbuilding, analyzing specific key aspects of this field and identifying which of them are valued the most by Navies and how they manage through life cycles of warships. Finally, the foundation of the proposed model is presented and also the basic grounds for implementing a Through Life Support (TLS) program are developed. As a result of this research, the proposed model for the naval industry is based on eleven (11) key principles: 1. The warship (a high added value product) must be designed and built in a shipyard at the country developing the defense program. 2. Design must be customer value oriented, i.e.warship must be designed to effectively fulfill its mission throughout its operational life, ensuring safety at the ship and for the people and protecting the environment in accordance with current regulations. 3. The industry has to provide integrated Through Life Support solutions. 4. Develop and maintain integrated complex systems capabilities for the entire warship life cycle. 5. Introduce the product, processes, people and business model itself to digital technologies. 6. Develop long-term action plans with the domestic customer. These plans must be based on three premises: (i) the complete life cycle must be included, starting from the research and development stage throughout the ship’s disposal; (ii) customer demand has to be sophisticated, i.e. customer requirements, both from the efficiency and product perspective, "attract" the contractor and (iii) technological level and manufacturing capabilities of the company in the future must be maintained and a competitive position on the export market has to be achieved. 7. Promote the military exporting sector through increased international business. 8. Develop contractor multi-location as it entails an opportunity for growth and promote export opportunities providing integrated solutions in the customer's country. 9. Strengthen institutional diplomacy as a lever for export. 10. Promote technological leadership in both product and processes with active R & D & I policies (Research & Development & Innovation) 11. Strengthen financing capacity through innovative solutions. The second goal of this thesis is focused on developing integrated Through Life Support (TLS) solutions. The proposed methodology tries to minimize the gap between needs and capabilities through the ship operational life. It means, the main TLS program objective is to maintain the ship’s performance and capabilities during operational life, in relative terms to current technologies, equivalent to those the ship had when it entered service. The main actions to fulfill the TLS program objectives are: value-oriented design, TLS engineering, technology updating projects, intelligent maintenance and performance based contracts.

Physical and social transformation processes that take place in urban contexts with strong spatial growth and hardly any economic development frequently have significant adverse impacts for the affected people, which tend to be made invisible. This paper presents an analytical framework to explore different ways to approach urban transformation processes (supply side), their impacts on the set of needs of the community (demand side) and their consequences on the urban environment as a whole (context). The proposed method has been used to assess three actions related to the physical and social transformation of the largest self-made settlement in the city of Dakar, Senegal, during the 2005–2012 period. Research findings show how exogenous interests are privileged over the common good when the affected citizens are not effectively involved in decision-making processes.

This dissertation investigates China’s recent shift in its climate change policy with a refined discourse approach. Methodologically, by adopting a neo-Gramscian notion of hegemony, a generative definition of discourse and an ontological pluralist position, the study constructs a theoretical framework named “discursive hegemony” that identifies the “social forces” for enabling social change and focuses on the role of discursive mechanisms via which the forces operate and produce effects. The key empirical finding of this study was that it was a co-evolution of conditions that shaped the outcome as China’s climate policy shift. In examining the case, a before-after within-case comparison was designed to analyze the variations in the material, institutional, and ideational conditions, with methods including interviews, conventional narrative/text analysis and descriptive statistics. Specifically, changes in energy use, the structure of decision-making body, and the narratives about sustainable development reflected how the above three types of social force processed in China in the first few years of the 21st century, causing the economic development agenda to absorb the climate issue, and turning the policy frame for the latter from mainly a diplomatic matter to a potential opportunity for better-quality growth. With the discursive operation of the “Science-based development”, China’s energy policy has been a good example of the Chinese understanding of sustainability characterized by economic primacy, ecological viability and social green-engineering. This way of discursive evolution, however, is a double-edged sword that has pushed forward some fast, top-down mitigation measures on the one hand, but has also created and will likely continue creating social and ecological havoc on the other hand. The study makes two major contributions. First and on the empirical level, because China is an international actor that was not expected to cooperate on the climate issue according to major IR theories, this study would add one critical case to the studies on global (environmental) governance and the ideational approach in the IR discipline. Second and on the theory-building level, the model of discursive hegemony can be a causally deeper mode of explanation because it traces the process of co-evolution of social forces.

While the topic of climate change is controversial, the world needs to take a precautionary approach to reduce carbon dioxide emissions. With growing populations and increasing energy demands, solutions to cleaner energy need to be developed and implemented. In order to successfully reduce carbon dioxide emissions, a global carbon pricing policy needs to be developed that includes all countries and allows each region to utilize the best clean energy technology options along with economic incentives that will be the most effective. The research conducted in this project validates the hypothesis that placing a monetary price on carbon will allow natural, technological, and financial resources to come together to implement a feasible energy solution that will reduce global carbon dioxide emissions.
