Climate change technology transfer to developing countries: evidence analysis and policy recommendations

Developing countries are experiencing unprecedented levels of economic growth. As a result, they will be responsible for most of the future growth in energy demand and greenhouse gas (GHG) emissions. Curbing GHG emissions in developing countries has become one of the cornerstones of a future international agreement under the United Nations Framework Convention for Climate Change (UNFCCC). However, setting caps for developing countries’ GHG emissions has encountered strong resistance in the current round of negotiations. Continued economic growth that allows poverty eradication is still the main priority for most developing countries, and caps are perceived as a constraint to future growth prospects. The development, transfer and use of low-carbon technologies have more positive connotations, and are seen as the potential path towards low-carbon development. So far, the success of the UNFCCC process in improving the levels of technology transfer (TT) to developing countries has been limited. This thesis analyses the causes for such limited success and seeks to improve on the understanding about what constitutes TT in the field of climate change, establish the factors that enable them in developing countries and determine which policies could be implemented to reinforce these factors. Despite the wide recognition of the importance of technology and knowledge transfer to developing countries in the climate change mitigation policy agenda, this issue has not received sufficient attention in academic research. Current definitions of climate change TT barely take into account the perspective of actors involved in actual climate change TT activities, while respective measurements do not bear in mind the diversity of channels through which these happen and the outputs and effects that they convey. Furthermore, the enabling factors for TT in non-BRIC (Brazil, Russia, India, China) developing countries have been seldom investigated, and policy recommendations to improve the level and quality of TTs to developing countries have not been adapted to the specific needs of highly heterogeneous countries, commonly denominated as “developing countries”. This thesis contributes to enriching the climate change TT debate from the perspective of a smaller emerging economy (Chile) and by undertaking a quantitative analysis of enabling factors for TT in a large sample of developing countries. Two methodological approaches are used to study climate change TT: comparative case study analysis and quantitative analysis. Comparative case studies analyse TT processes in ten cases based in Chile, all of which share the same economic, technological and policy frameworks, thus enabling us to draw conclusions on the enabling factors and obstacles operating in TT processes. The quantitative analysis uses three methodologies – principal component analysis, multiple regression analysis and cluster analysis – to assess the performance of developing countries in a number of enabling factors and the relationship between these factors and indicators of TT, as well as to create groups of developing countries with similar performances. The findings of this thesis are structured to provide responses to four main research questions: What constitutes technology transfer and how does it happen? Is it possible to measure technology transfer, and what are the main challenges in doing so? Which factors enable climate change technology transfer to developing countries? And how do different developing countries perform in these enabling factors, and how can differentiated policy priorities be defined accordingly? vi Resumen Los paises en desarrollo estan experimentando niveles de crecimiento economico sin precedentes. Como consecuencia, se espera que sean responsables de la mayor parte del futuro crecimiento global en demanda energetica y emisiones de Gases de Efecto de Invernadero (GEI). Reducir las emisiones de GEI en los paises en desarrollo es por tanto uno de los pilares de un futuro acuerdo internacional en el marco de la Convencion Marco de las Naciones Unidas para el Cambio Climatico (UNFCCC). La posibilidad de compromisos vinculantes de reduccion de emisiones de GEI ha sido rechazada por los paises en desarrollo, que perciben estos limites como frenos a su desarrollo economico y a su prioridad principal de erradicacion de la pobreza. El desarrollo, transferencia y uso de tecnologias bajas en carbono tiene connotaciones mas positivas y se percibe como la via hacia un crecimiento bajo en carbono. Hasta el momento, la UNFCCC ha tenido un exito limitado en la promocion de transferencias de tecnologia (TT) a paises en desarrollo. Esta tesis analiza las causas de este resultado y busca mejorar la comprension sobre que constituye transferencia de tecnologia en el area de cambio climatico, cuales son los factores que la facilitan en paises en desarrollo y que politicas podrian implementarse para reforzar dichos factores. A pesar del extendido reconocimiento sobre la importancia de la transferencia de tecnologia a paises en desarrollo en la agenda politica de cambio climatico, esta cuestion no ha sido suficientemente atendida por la investigacion existente. Las definiciones actuales de transferencia de tecnologia relacionada con la mitigacion del cambio climatico no tienen en cuenta la diversidad de canales por las que se manifiestan o los efectos que consiguen. Los factores facilitadores de TT en paises en desarrollo no BRIC (Brasil, Rusia, India y China) apenas han sido investigados, y las recomendaciones politicas para aumentar el nivel y la calidad de la TT no se han adaptado a las necesidades especificas de paises muy heterogeneos aglutinados bajo el denominado grupo de "paises en desarrollo". Esta tesis contribuye a enriquecer el debate sobre la TT de cambio climatico con la perspectiva de una economia emergente de pequeno tamano (Chile) y el analisis cuantitativo de factores que facilitan la TT en una amplia muestra de paises en desarrollo. Se utilizan dos metodologias para el estudio de la TT a paises en desarrollo: analisis comparativo de casos de estudio y analisis cuantitativo basado en metodos multivariantes. Los casos de estudio analizan procesos de TT en diez casos basados en Chile, para derivar conclusiones sobre los factores que facilitan u obstaculizan el proceso de transferencia. El analisis cuantitativo multivariante utiliza tres metodologias: regresion multiple, analisis de componentes principales y analisis cluster. Con dichas metodologias se busca analizar el posicionamiento de diversos paises en cuanto a factores que facilitan la TT; las relaciones entre dichos factores e indicadores de transferencia tecnologica; y crear grupos de paises con caracteristicas similares que podrian beneficiarse de politicas similares para la promocion de la transferencia de tecnologia. Los resultados de la tesis se estructuran en torno a cuatro preguntas de investigacion: .Que es la transferencia de tecnologia y como ocurre?; .Es posible medir la transferencia de tecnologias de bajo carbono?; .Que factores facilitan la transferencia de tecnologias de bajo carbono a paises en desarrollo? y .Como se puede agrupar a los paises en desarrollo en funcion de sus necesidades politicas para la promocion de la transferencia de tecnologias de bajo carbono?

c&d-learning implementation architecture: Adapting e-learning to developing countries

From the educational point of view, the most widespread method in developing countries is on-site education. Technical and economic resources cannot support conventional distance learning infrastructures and it is even worse for courses in universities. They usually suffer a lack of qualified faculty staff, especially in technical degrees. The literature suggest that e-learning is a suitable solution for this problem, but its methods are developed attending to educational necessities of the First World and cannot be applied directly to other contexts. The proposed methodology is a variant of traditional e-learning adapted to the needs of developing countries. E-learning for Cooperation and Development (c&d-learning) is oriented to be used for educational institutions without adequate technical or human resources. In this paper we describe the c&d-learning implementation architecture based on three main phases: hardware, communication and software; e.g. computer and technical equipping, internet accessing and e-learning platform adaptation. Proper adaptation of educational contents to c&d-learning is discussed and a real case of application in which the authors are involved is described: the Ngozi University at Burundi.

Identification of a biomarker panel for colorectal cancer diagnosis

Background Malignancies arising in the large bowel cause the second largest number of deaths from cancer in the Western World. Despite progresses made during the last decades, colorectal cancer remains one of the most frequent and deadly neoplasias in the western countries. Methods A genomic study of human colorectal cancer has been carried out on a total of 31 tumoral samples, corresponding to different stages of the disease, and 33 non-tumoral samples. The study was carried out by hybridisation of the tumour samples against a reference pool of non-tumoral samples using Agilent Human 1A 60-mer oligo microarrays. The results obtained were validated by qRT-PCR. In the subsequent bioinformatics analysis, gene networks by means of Bayesian classifiers, variable selection and bootstrap resampling were built. The consensus among all the induced models produced a hierarchy of dependences and, thus, of variables. Results After an exhaustive process of pre-processing to ensure data quality--lost values imputation, probes quality, data smoothing and intraclass variability filtering--the final dataset comprised a total of 8, 104 probes. Next, a supervised classification approach and data analysis was carried out to obtain the most relevant genes. Two of them are directly involved in cancer progression and in particular in colorectal cancer. Finally, a supervised classifier was induced to classify new unseen samples. Conclusions We have developed a tentative model for the diagnosis of colorectal cancer based on a biomarker panel. Our results indicate that the gene profile described herein can discriminate between non-cancerous and cancerous samples with 94.45% accuracy using different supervised classifiers (AUC values in the range of 0.997 and 0.955)

Optimización de la metodología de contratación de carbones térmicos con destino a la generación eléctrica

En los últimos quince años se ha producido una liberalización de los mercados eléctricos en los distintos países de ámbito occidental que ha ido acompañado de un incremento por la preocupación por la incidencia de las distintas tecnologías de generación en el entorno medioambiental. Ello se ha traducido en la aparición de un marco regulatorio más restrictivo sobre las tecnologías de generación fósiles, con mayor incidencia en las derivadas de productos petrolíferos y carbón. A nivel mundial han ido apareciendo cambios normativos relativos a las emisiones de distintos elementos contaminantes (CO2, SO2, NOx…), que hacen que en particular las centrales térmicas de carbón vean muy afectadas su rentabilidad y funcionamiento. Esta situación ha supuesto que la tecnología de generación eléctrica con carbón haya avanzado considerablemente en los últimos años (calderas supercríticas, sistemas de desulfuración, gasificación del carbón…). No obstante, el desarrollo de la generación con energías renovables, la generación con gas mediante centrales de ciclo combinado y la opinión social relativa a la generación con carbón, principalmente en Europa, suponen un serio obstáculo a la generación con carbón. Por consiguiente, se hace necesario buscar vías para optimizar la competitividad de las centrales de carbón y el camino más razonable es mejorar el margen esperado de estas plantas y en particular el coste de adquisición del carbón. Ello se hace aún más importante por el hecho de existir numerosas centrales de carbón y un elevado número de nuevos proyectos constructivos de centrales de carbón en países asiáticos. Por consiguiente, el objeto de la presente tesis doctoral se centra en definir una metodología para optimizar la compra de carbón, desde el punto de vista económico y técnico, con destino a su consumo en una central térmica, con ello reducir el coste del carbón consumido y mejorar su competitividad. También se enfoca a determinar que herramientas pueden ser utilizadas para optimizar la gestión del carbón después de su compra y con ello abrir la posibilidad de obtener márgenes adicionales para dicho carbón. De acuerdo con este objetivo, el autor de la presente Tesis Doctoral realiza tres aportaciones novedosas en el ámbito de la contratación de carbón térmico y su optimización posterior: - Evaluación de carbones para su adquisición considerando el efecto de la calidad del carbón en el coste de generación asociado a cada carbón ofertado. - Creación, desarrollo, implantación y utilización de una potente herramienta de planificación de Combustibles. Esta herramienta, está diseñada con el objeto de determinar la solución económica óptima de aprovisionamientos, consumos y niveles de existencias para un parque de generación con centrales de carbón y fuelóleo. - La extensión de una metodología contractual habitual en el mercado spot de Gas Natural Licuado, a la contratación spot de Carbón de Importación. Esta se basa en el desarrollo de Acuerdos Marcos de Compra/Venta de carbón, que por su flexibilidad permitan obtener resultados económicos adicionales después de la compra de un carbón. Abstract In the last fifteen years, a liberalization of the electrical markets has occurred in the western countries. This process has been accompanied by an increasing concern of the impact of the different generation technologies towards the environment. This has motivated a regulated framework restricting the use of fossil fuels, impacting a great deal in coal and oil based products. Worldwide, new legal changes have been arising related to the emissions of the different pollutants (CO2, SO2, NOx…). These changes have had a deep impact in the feasibility, profit and running of coal fired power plants. This situation has motivated the coal electrical generation technologies to move forward in an important way in the last few years (supercritical furnaces, desulphuration plants, coal gasification…). Nevertheless, the development of the renewable generation, the gas combined cycle generation and the social opinion related to the coal electrical generation, mainly in Europe, have created a serious obstacle to the generation of electricity by coal. Therefore it is necessary to look for new paths in order to optimize the competitiveness of the coal fired power plants and the most reasonable way is to improve the expected margin of these plants and particularly the coal purchase cost. All of the above needs to be taken into context with the large number of existing coal fired power plants and an important number of new projects in Asian countries. Therefore, the goal of the current doctoral dissertation is focused to define a methodology to be considered in order to optimize the coal purchase, from an economical and a technical point of view. This coal, destined for power plant consumption, permits the reduction of consumption coal cost and improves the plant’s competitiveness. This document is also focused to define what tools we can use to optimize the coal management after deal closing and therefore open the possibility to get further margins. According to this goal, the author of this doctoral dissertation provides three important new ideas in the ambit of contracting steam coal and the posterior optimization: - Evaluation of coal purchases, considering the effect of coal quality on the cost of generation associated with each type of coal offered. - The creation, development, deployment and use of a strong planning tool of fuels. This tool is designed for the purpose of determining the optimal economic solution of fuel supply, consumption and stock levels for a power generation portfolio using coal and fuel oil fired power plants. - The application of a common contractual methodology in the spot market of Liquid Natural Gas, for the contracting spot imported coal. This is based on the development of Framework Agreements for the Purchasing / Sale of coal, which because of its flexibility allows for the gain of additional financial results after the purchase of coal.

Identification of thaumatin-like protein and aspartyl protease as new major allergens in lettuce (Lactuca sativa)

Scope: Today, about 2–8% of the population of Western countries exhibits some type of food allergy whose impact ranges from localized symptoms confined to the oral mucosa to severe anaphylactic reactions. Consumed worldwide, lettuce is a Compositae family vegetable that can elicit allergic reactions. To date, however, only one lipid transfer protein has been described in allergic reaction to lettuce. The aim of this study was to identify potential new allergens involved in lettuce allergy. Methods and results: Sera from 42 Spanish lettuce-allergic patients were obtained from pa-tients recruited at the outpatient clinic. IgE-binding proteins were detected by SDS-PAGE and immunoblotting. Molecular characterization of IgE-binding bands was performed by MS. Thaumatin was purified using the Agilent 3100 OFFGEL system. The IgE-binding bands recognized in the sera of more than 50% of patients were identified as lipid transfer protein (9 kDa), a thaumatin-like protein (26 kDa), and an aspartyl protease (35 and 45 kDa). ELISA inhibition studies were performed to confirm the IgE reactivity of the purified allergen. Conclusion: Two new major lettuce allergens—a thaumatin-like protein and an aspartyl protease—have been identified and characterized. These allergens may be used to improve both diagnosis and treatment of lettuce-allergic patients.

Electron transport and azimuthal oscillations in hall thrusters

The Hall Effect Thruster (HET) is a type of satellite electric propulsion device initially developed in the 1960’s independently by USA and the former USSR. The development continued in the shadow during the 1970’s in the Soviet Union to reach a mature status from the technological point of view in the 1980’s. In the 1990’s the advanced state of this Russian technology became known in western countries, which rapidly restarted the analysis and development of modern Hall thrusters. Currently, there are several companies in USA, Russia and Europe manufacturing Hall thrusters for operational use. The main applications of these thrusters are low-thrust propulsion of interplanetary probes, orbital raising of satellites and stationkeeping of geostationary satellites. However, despite the well proven in-flight experience, the physics of the Hall Thruster are not completely understood yet. Over the last two decades large efforts have been dedicated to the understanding of the physics of Hall Effect thrusters. However, the so-called anomalous diffusion, short name for an excessive electron conductivity along the thruster, is not yet fully understood as it cannot be explained with classical collisional theories. One commonly accepted explanation is the existence of azimuthal oscillations with correlated plasma density and electric field fluctuations. In fact, there is experimental evidence of the presence of an azimuthal oscillation in the low frequency range (a few kHz). This oscillation, usually called spoke, was first detected empirically by Janes and Lowder in the 1960s. More recently several experiments have shown the existence of this type of oscillation in various modern Hall thrusters. Given the frequency range, it is likely that the ionization is the cause of the spoke oscillation, like for the breathing mode oscillation. In the high frequency range (a few MHz), electron-drift azimuthal oscillations have been detected in recent experiments, in line with the oscillations measured by Esipchuk and Tilinin in the 1970’s. Even though these low and high frequency azimuthal oscillations have been known for quite some time already, the physics behind them are not yet clear and their possible relation with the anomalous diffusion process remains an unknown. This work aims at analysing from a theoretical point of view and via computer simulations the possible relation between the azimuthal oscillations and the anomalous electron transport in HET. In order to achieve this main objective, two approaches are considered: local linear stability analyses and global linear stability analyses. The use of local linear stability analyses shall allow identifying the dominant terms in the promotion of the oscillations. However, these analyses do not take into account properly the axial variation of the plasma properties along the thruster. On the other hand, global linear stability analyses do account for these axial variations and shall allow determining how the azimuthal oscillations are promoted and their possible relation with the electron transport.

Business, development and inclusive supply chains. Exploring pathways for the sustainable incorporation of the poor as suppliers in agrifood supply chains

El panorama global está cambiando, y esto influye sobre la forma en la que entendemos y tratamos de alcanzar un desarrollo humano sostenible. El crecimiento de la población conlleva una mayor presión sobre los recursos, pero también supone una mayor cantidad de mano de obra y de talento; la concentración en áreas urbanas está cambiando las dinámicas sociales y desafiando los canales de comercialización tradicionales, pero también genera nuevos mercados y fomenta la innovación; los cambios en la economía global están reduciendo los tradicionales desequilibrios de poder entre los países occidentales y el resto del mundo; y las crecientes interconexiones crean nuevos riesgos pero también oportunidades para lanzar iniciativas de alcance global. Todas estas tendencias nos están obligando a repensar qué es el desarrollo humano y de qué manera deberíamos afrontar el reto de la pobreza. Es comúnmente aceptado que la globalización implica interdependencia y que, para conseguir un desarrollo humano sostenible, la colaboración entre actores de distintos ámbitos es necesaria. Se observa una creciente convergencia de temas, intereses y soluciones en torno al desarrollo sostenible, incluso en diferentes países y sectores, lo que está facilitando la colaboración estratégica entre empresas, gobiernos y sociedad civil. Existen pocas duda a día de hoy sobre el papel fundamental que las empresas deben desempeñar en la transición mundial hacia la sostenibilidad ambiental y la erradicación de la pobreza. Las empresas están evolucionando desde un enfoque tradicional centrado en la maximización de beneficios económicos hacia un enfoque holístico que integra la sostenibilidad y la responsabilidad social como parte del núcleo de negocio de las compañías. En el ámbito medioambiental, muchas empresas ya han comenzado a actuar y tratan de reducir sus emisiones, sus desechos y su consumo de energía. Sin embargo la contribución de las empresas a la reducción de la pobreza no está tan clara. Actualmente en torno a 1,2 miles de millones de personas viven en situación de extrema pobreza. La mayoría de estas personas aún vive en zonas rurales donde la mayor parte de la población activa trabaja en el sector agrícola. Por lo tanto, mejorar las oportunidades y reducir los riesgos de los productores más vulnerables en el sector de la agricultura puede ser un motor de desarrollo rural y reducción de la pobreza, especialmente en países de bajo nivel de desarrollo cuyas economías están fundamentalmente basadas en la agricultura. Algunas empresas comienzan a incluir a los pobres en sus operaciones como consumidores, proveedores y emprendedores. Esta tesis se centra en las potenciales oportunidades relacionadas con la incorporación sostenible de los pobres como proveedores de productos y/o de mano de obra. La colaboración entre empresas y productores vulnerables de países en desarrollo es un tema relativamente nuevo y todavía poco estudiado. La pregunta que guía esta tesis es: “¿Cómo pueden las empresas facilitar la inclusión sostenible en cadenas de suministro de productores vulnerables de los países menos desarrollados?”. Para responder a la pregunta anterior, la autora ha aplicado una metodología de casos de estudio. Esta metodología se considera apropiada porque la investigación sobre cadenas de suministro inclusivas es todavía escasa y porque es necesario entender en profundidad un fenómeno de la vida real, y para ello es fundamental conocer su contexto. En primer lugar, se realiza una revisión de literatura para identificar las proposiciones y los constructos teóricos que guiarán la posterior recogida de datos. La revisión de literatura se divide en dos partes: una más general que explora la dimensión social de la sostenibilidad en cadenas de suministro, y una más específica que se centra en la incorporación de los pobres como proveedores en cadenas de suministro. A lo largo de la última década, ha habido un crecimiento exponencial de los estudios académicos sobre la sostenibilidad de las cadenas de suministro, pero la mayoría de los esfuerzos se han dirigido hacia la dimensión medioambiental de la sostenibilidad. Por lo tanto la revisión de literatura, que se presenta en la Sección 3.1 (página 35) y que profundiza en la sostenibilidad social de las cadenas de suministro, puede considerarse una contribución en sí misma. Esta revisión de literatura revela que la investigación sobre aspectos sociales en cadenas de suministro está cobrando impulso en distintas áreas de conocimiento, principalmente en los ámbitos de investigación sobre “gestión de cadenas de suministro”, “responsabilidad social corporativa” y “estudios del desarrollo”. La investigación existente sobre sostenibilidad social de cadenas de suministro se centra en tres temas: aclarar la definición de sostenibilidad social; analizar la implementación de estrategias de sostenibilidad social en cadenas de suministro; y estudiar el apoyo de las em presas líderes a proveedores vulnerables para facilitar su transición hacia la sostenibilidad. Un marco conceptual que resume los principales hallazgos de esta primera parte de la revisión de literatura es planteado en la Figura 7 (página 48). No obstante, en el área de investigación que está emergiendo en torno a la sostenibilidad social de las cadenas de suministro, los estudios relacionados con la reducción de la pobreza son aún escasos. Además se aprecia una falta de contribuciones desde y sobre los países menos desarrollados, así como una clara tendencia a reflejar la visión de las empresas líderes de las cadenas de suministro, olvidando la perspectiva de los proveedores. La segunda parte de la revisión de literatura presentada en la Sección 3.2 (página 51) profundiza en tres líneas de investigación que exploran, desde distintas perspectivas, la inclusión de los pobres en cadenas de suministro. Estas líneas son “Global Value Chains” (GVC), “Base of the Pyramid” (BoP) y “Sustainable Supply Chain Management” (SSCM). La investigación en GVC analiza las cadenas de suministro desde la perspectiva de la globalización económica y el comercio internacional, poniendo especial énfasis en las implicaciones para los países en desarrollo y las comunidades vulnerables. GVC caracteriza las cadenas de suministro según la forma en la que son gobernadas, las oportunidades de mejora que existen para los productores que forman parte de la cadena y el grado de inclusión o exclusión de las comunidades más pobres y vulnerables. La investigación en BoP explora las relaciones comerciales entre empresas y comunidades pobres. La premisa fundamental del concepto BoP es la posibilidad de combinar la generación de beneficios con la reducción de la pobreza. La propuesta original es que mediante la venta de productos y servicios a las comunidades pobres de países en desarrollo, la pobreza puede ser reducida al tiempo que las empresas incrementan sus beneficios, especialmente las grandes empresas multinacionales. Esta idea ha ido evolucionando y, a día de hoy, los investigadores BoP consideran la incorporación de los pobres no sólo como consumidores sino también como empleados, proveedores y co-creadores. La investigación en SSCM ha estado fundamentalmente orientada al estudio de la dimensión medioambiental de la sostenibilidad de cadenas de suministro. Sin embargo, la creciente externalización de la producción a países en desarrollo y las demandas de los grupos de interés para que las empresas aborden todos los aspectos de la sostenibilidad han llevado a los académicos de SSCM a reconocer la importancia de integrar asuntos relacionados con la reducción de la pobreza en sus investigaciones. Algunos estudios comienzan a apuntar los principales retos a los que se enfrentan las empresas para colaborar con productores vulnerables en sus cadenas de suministro. Estos retos son: falta de comunicación, altos costes de transacción y el incremento de la complejidad de las operaciones. Las contribuciones de estas tres líneas de investigación son complementarias para el estudio de las cadenas de suministro inclusivas. Sin embargo, raramente han sido consideradas conjuntamente, ya que pertenecen a ámbitos de conocimiento distintos. Esta tesis integra las aportaciones de GVC, BoP y SSCM en un marco conceptual para la creación y gestión de cadenas de suministro inclusivas. Este marco conceptual para cadenas de suministro inclusivas queda representado en la Figura 9 (página 68). El marco conceptual refleja las motivaciones que llevan a las empresas a colaborar con productores vulnerables, los retos a los que se enfrentan al hacerlo, y los caminos o estrategias que están siguiendo para construir y operar cadenas de suministro inclusivas de manera que sean beneficiosas tanto para la empresa como para los productores vulnerables. A fin de validar y refinar el marco conceptual propuesto, tres casos de estudio se llevan a cabo. Las cadenas de suministro analizadas por los casos de estudio pertenecen al sector agrícola y sus principales proveedores se encuentran en países de África subsahariana. Múltiples métodos de recolección de datos y triangulación son utilizados para mejorar la fiabilidad de los datos. La autora desarrolló trabajos de campo en Senegal, Etiopía y Tanzania. Estos viajes permitieron enriquecer el proceso de recogida de información mediante entrevistas semiestructuradas y conversaciones informales con los principales actores de la cadena de suministro y mediante la observación directa de los procesos y las interacciones entre productores vulnerables y empresas. El Caso de estudio A (Sección 5.1 en página 96) es un caso de estudio único. Analiza la cadena de suministro local de verduras en Senegal. La organización focal es Manobi, una empresa senegalesa que provee servicios de bajo coste a emprendedores locales del sector agrícola. El Caso de estudio A proporciona un interesante análisis del funcionamiento de una cadena de suministro local en un país en desarrollo y muestra como la provisión de servicios profesionales puede mejorar el desempeño de productores vulnerables. El Caso de estudio B (Sección 5.2 en página 122) es un caso de estudio único. Analiza la cadena de suministro global de flor cortada con origen en Etiopía. La organización focal es EHPEA, la Asociación Etíope de Productores y Exportadores Hortícolas, cuya misión es promover y salvaguardar la posición competitiva del sector agrícola etíope en el mercado global. El Caso de estudio B ayuda a comprender mejor la perspectiva de los proveedores respecto a los requerimiento de sostenibilidad del mercado global. También muestra cómo la inclusión de los productores en el proceso de desarrollo de un estándar privado facilita su implementación posterior. El Caso de estudio C (Sección 5.3 en página 143) es un caso de estudio múltiple. Analiza la cadena de suministro global de café especial con origen en Tanzania. Las organizaciones focales son comerciantes que conectan de manera directa a pequeños agricultores de café en países en desarrollo con empresas tostadoras de café en países desarrollados. El Caso de estudio C muestra cómo un pequeño agricultor puede proveer un producto “premium” al mercado global, y participar en un segmento diferenciado del mercado a través de una cadena de suministro transparente y eficiente. Las aportaciones empíricas de los casos de estudio ayudan a validar y mejorar el marco conceptual sobre cadenas de suministro inclusivas (ver discusión en el Capítulo 6 en página 170). El resultado es la propuesta de una nueva versión del marco conceptual representado en la Figura 40 (página 195). Los casos de estudio también proporcionan interesantes aportaciones en relación a la gestión de cadenas de suministro inclusivas y muestran las perspectivas de distintos actores implicados. Esta tesis arroja luz sobre el papel de las empresas en la creación y la gestión de cadenas de suministro inclusivas llevando a cabo una revisión de literatura multidisciplinar y analizando tres casos de estudio en países africanos. Como resultado, esta tesis presenta una serie de contribuciones empíricas y teóricas al ámbito de investigación emergente en torno a las cadenas de suministro inclusivas (Capítulo 7). Esta tesis también pretende ser útil a profesionales que deseen facilitar la incorporación de los pobres como proveedores en condiciones justas y beneficiosas. ABSTRACT The global outlook is changing, and this is influencing the way we understand and try to achieve sustainable human development. Population growth entails increasing pressure over resources, but it also provides greater workforce and talent; concentration in urban areas is changing social dynamics and challenging traditional marketing channels, but also creating news markets and driving innovation; the global economy shift is rebalancing the traditional power imbalance between Western countries and the rest of the world, making new opportunities to arise; and interconnections and global interdependence create new risks but also opportunities for launching initiatives with a global reach. All these trends are impelling us to rethink what development is and in which way poverty alleviation should be approached. It is generally agreed that globalization implies interdependence and, in order to achieve sustainable human development, collaboration of all actors is needed. A convergence of issues, interests and solutions related to sustainable development is being observed across countries and sectors, encouraging strategic collaboration among companies, governments and civil society. There is little doubt nowadays about the crucial role of the private sector in the world’s path towards environmental sustainability and poverty alleviation. Businesses are evolving from a “business as usual” stance to a more sustainable and responsible approach. In the environmental arena, many companies have already “walk the talk”, implementing environmental management systems and trying to reduce emissions and energy consumption. However, regarding poverty alleviation, their contribution is less clear. There are around 1.2 billion people living in extreme poverty. Most of this people still live in rural areas where the agricultural sector employs a big part of the active population. Therefore, improving opportunities and reducing risks for vulnerable producers in the agri-food sector can be a primary engine of rural development and poverty alleviation, particularly in the poor, agriculture-based economies of least developed countries. Some companies are beginning to include the poor into their operations as consumers, suppliers and entrepreneurs. This thesis focuses specifically on the potential opportunities related to the sustainable incorporation of the poor as suppliers of products and/or labor. Business collaboration with vulnerable producers in developing countries is a relatively new trend and it is still understudied. The overall question guiding this thesis is: “How can businesses facilitate the sustainable inclusion of vulnerable producers from least developed countries into supply chains?”. In order to answer the research question, the author has applied a case study research strategy. This methodology is considered appropriate because research about inclusive supply chains is still at an early stage, and because there is a need to understand a real-life phenomenon in depth, but such understanding encompasses important contextual conditions. First, a literature review is conducted, in order to identify the research propositions and theoretical constructs that will guide the data collection. The literature review is divided in two parts: a more general one that explores the social dimension of sustainability of supply chains, and a more specific one that focuses on the incorporation of the poor as suppliers in supply chains. During the last decade, there has been an exponential growth of studies in the field of supply chain sustainability, but research efforts have traditionally been directed towards the analysis of the environmental dimension. Therefore, the literature review presented in Section 3.1 (page 35) that delves into social sustainability of supply chains can be considered a contribution in itself. This literature review reveals that the investigation of social issues in supply chains is gaining momentum and comes from different academic disciplines, namely Supply Chain Management, Corporate Social Responsibility and Development Studies. Existing research about social sustainability of supply chains focuses on three issues: clarify the definition of social sustainability; analyze the implementation of social sustainability strategies in supply chains; and study lead companies’ support to vulnerable suppliers in their transition towards sustainability. A conceptual framework that outlines the main findings that emerge from this first part of literature review is proposed in Figure 7 (page 48). Nevertheless, in this nascent field of social sustainability of supply chains, studies related to poverty alleviation are still scarce. Moreover, a lack of contributions from and about least developed countries has been observed, as well as a tendency to reflect on the lead firms’ standpoint, neglecting the suppliers’ perspective. The second part of the literature review (Section 3.2 in page 51) delves into three research streams that are exploring the inclusion of the poor into supply chains from different viewpoints. These research streams are Global Value Chains (GVC), Base of the Pyramid (BoP) and Sustainable Supply Chain Management (SSCM). GVC research discusses the dynamics of economic globalization and international trade, putting special emphasis in the implications for developing countries and vulnerable communities. GVC characterizes supply chains by the way they are governed, the upgrading opportunities that exist for producers in the chain and the degree of inclusion or exclusion of impoverished communities. BoP research explores trading relationships between businesses and impoverished communities. The core premise of the BoP concept is the possibility to combine profits with poverty alleviation. The original BoP proposition is that by marketing innovative products and services to poor communities in developing countries, poverty would be reduced and companies would increase their benefits, especially multinational companies. This idea has evolved to consider the incorporation of the poor to business activities not only as consumers, but also as employees, entrepreneurs and co-creators. The SSCM school of thought has mainly focused on studying the environmental dimension of supply chain sustainability, neglecting the consideration of the social perspective. However, in recent years, increasing outsourcing of production to developing countries and stakeholders’ demands for a more holistic approach to business sustainability have led SSCM scholars to acknowledge the importance of integrating poverty concerns in this field’s research agenda. Some SSCM studies identify the main operational challenges for companies which engage with vulnerable suppliers in their supply chains: missing communication, higher transactional and operational costs and increased complexity. Contributions from these three research streams are complementary for the study of inclusive supply chains. However, they have been rarely considered together, since they belong to different research areas. This thesis seeks to play a dovetailing role in this scenario by proposing a conceptual framework for creating and operating inclusive supply chains that builds on contributions from GVC, SSCM and BoP research. This framework for inclusive supply chains is depicted in Figure 9 (page 68), and explains the motivations that drive businesses to collaborate with vulnerable suppliers, the chal lenges they face in doing so, and the pathways they are following in order to build and operate inclusive supply chains profitably for both buying companies and vulnerable suppliers. In order to validate and refine the proposed framework, three case studies are carried out. The supply chains analyzed by the case studies belong to the agri-food sector and source from Sub-Saharan African countries. Multiple data collection methods and triangulation are used in order to improve reliability of findings. The author carried out field work in Senegal, Ethiopia and Tanzania. These travels enriched the data collection process, providing semi-structured interviews and informal conversations with the main actors in the supply chains, as well as direct observation of processes and interactions among companies and vulnerable suppliers. Case study A (Section 5.1 in page 96) is a single case study. It analyzes a local supply chain in Senegal providing vegetables to the local market. The focal organization is Manobi, a Senegalese inclusive business which provides affordable ICT services to local entrepreneurs in the agri-food sector. Case study A provides interesting insights into the dynamics of local supply chains and how professional services can help to improve their performance. Case study B (Section 5.2 in page 122) is a single case study. It analyzes a global supply chain with origin in Ethiopia providing cut flowers to the global commodity market. The focal organization is EHPEA, Ethiopian Horticulture Producers and Exporters Association, whose mission is to promote and safeguard the competitive position of the Ethiopian horticulture sector within the global market. Case study B helps to better understand the suppliers’ perspective regarding global market sustainability requirements and shows how the inclusion of suppliers in the process of development of a private standard has a positive impact in its implementation. Case study C (Section 5.3 in page 143) is a multiple case study. It analyzes a global supply chain with origin in Tanzania providing coffee to the global niche market of specialty coffee. The focal organizations are traders who are directly connecting smallholder coffee farmers in developing countries to coffee roasters in developed countries. Case study C shows how smallholder farmers can supply a premium product and be incorporated in a differentiated market segment through a transparent and efficient supply chain. The empirical findings from the case studies help to validate and refine the conceptual framework (see discussion in Chapter 6). The proposal of a new version of the conceptual framework is depicted in Figure 40 (page 195). The case studies also provide interesting insights related to the management of inclusive supply chains and show the perspectives of the different actors involved. This thesis sheds some light on the role of businesses in the creation and operation of inclusive supply chains by carrying out a cross-disciplinary literature review and analyzing three case studies in African countries. In doing so, this thesis presents a series of theoretical and empirical contributions to the emerging academic field of inclusive supply chains (Chapter 7). This thesis also intends to be useful to practitioners willing to improve the incorporation of the poor as suppliers in fair and profitable conditions.

La casa en imágenes : pulsos, ecos y huellas del habitar contemporáneo

La imagen fotográfica es un bloque espacio tiempo congelado, un fragmento referido al antes y el después de algo. Al contemplar una fotografía de un interior doméstico, descubrimos un entretejido sutil entre el habitante y su hábitat. Somos capaces de recaer en más detalles de los que el ojo humano puede apreciar en su visión cotidiana, siempre ligada al devenir espacio temporal. El acto de fotografiar el hogar, de congelar unidades habitadas infinitesimales, se revela como una manifestación radical del modo unipersonal de habitar de cada fotógrafo, profesional o aficionado, y por extensión, dado que hoy todos somos fotógrafos; de cada habitante. Por un lado, la fotografía se piensa aquí como herramienta, capaz de desvelar, de poner en el mundo, los elementos, percepciones y acontecimientos, que subyacen imbricados en la construcción del hogar. Por otro, la imagen se entiende como medio de expresión y de comunicación, como el lenguaje universal de nuestro tiempo, por todos conocido y utilizado. En este momento de interconexión máxima, entre redes, datos y capas de cognición, de velocidad y aceleración, esta tesis doctoral se plantea como una vuelta a la reflexión, a la contemplación del objeto imagen, desde la certeza de que para que ésta hable hay que darle tiempo. Así, la investigación hay que entenderla desde una base ontológica y fenomenológica; desde la experiencia del ser que habita un entorno concreto y determinado. Se enmarca en el actual entorno socio cultural de occidente, se busca desvelar el significado y modo de habitar del habitante común, poniendo de manifiesto aquello que acontece para que una casa cualquiera, de un habitante cualquiera, devenga hogar. Los primeros indicios sobre el tema surgirán del análisis y la reinterpretación hermenéutica de un atlas de imágenes del habitar: cuerpo de imágenes reunido a partir de series fotográficas de hogares, de habitantes anónimos, puestos a luz por la mirada de un grupo de artistas. Posteriormente, ponemos a prueba el conocimiento adquirido en el análisis anterior, mientras que expandimos la investigación hacia el sentir del habitante común, mediante la realización de tres experimentos participativos, o estudios de campo cualitativos. Los resultados, de ambos grupos de casos de estudio, se compilan, organizan y estructuran en una taxonomía del habitar. Esta taxonomía está compuesta por cuarenta y siete parámetros, que explicitan la naturaleza compleja del hogar del siglo XXI. Este hogar es entendido como un constructo personal de cada habitante, un proceso que acontece en el tiempo y en el espacio, y que entraña la propia construcción del habitante. Esta extensa taxonomía se organiza según tres ámbitos del ser humano, en el primero se expresan los factores relacionados con el modo de "estar físicamente" en el hogar, incluyendo: al propio habitante, la casa como espacio arquitectónico y como materialidad: objetos, muebles, iconos y símbolos que pueblan el hogar. En segundo lugar, se manifiestan los parámetros relacionados con el modo de “percibir”: por un lado, aquello que se deriva de lo que se ve, y por otro, lo que se deriva de aquello que no se ve, pero se siente. En tercer lugar, se explicitan los factores relativos al habitante que "crea/juega" su hogar, quién por un lado, es en el mundo actuando, y que por otro, siente el mundo construyéndolo mediante una serie de relaciones que establece con él. Finalmente, la investigación intenta revelar las sinergias, conexiones y relaciones, entre todos estos elementos extraídos del sentir del habitante común, y que fueron inducidos mediante el análisis y reinterpretación de los casos de estudio, poniendo de manifiesto un orden de cosas en el habitar occidental contemporáneo. ABSTRACT The photographic image is a frozen space time block, a fragment referred to a something before and after. When we stare at the photography of domestic interiors we discover a subtle interweaving between the inhabitant and her habitat. We are able to acknowledge infinite more details than the human eye, in its continuous quotidian vision always linked to the space time progression, appreciates. The act of photographing the home, of freezing infinitesimal inhabited units, reveals as a radical statement of the concept of inhabiting for each photographer, professional or amateur, and by extension, as we today all are photographers, for each inhabitant. On the one hand, photography is here conceived as a tool that is capable of revealing, "of placing in the world" the elements, perceptions and happenings that underlie imbricated in the construction of a home. On the other hand, image is thought as an expression and communication media, as the universal language of our time (as far as it is known and used by all of us). In this precise moment of maximum interconnection between networks, data and cognitive layers; of speed and acceleration, this PhD Dissertation is conceived as a return to reflection; to the contemplation of object image, from the certainty of its need of time for talking. Therefore, this research from an ontological and phenomenological base; from the experience of the self who inhabits a determined and concrete environment, that of the western countries at the present, pursues to unveil the meaning and way of inhabiting of a common dweller and manifest what conforms the transformation of any house, of any inhabitant into a home. The first clues will arise from the analysis and hermeneutical reinterpretation of the Atlas of inhabiting; an assembled body of images of anonymous inhabitants houses, brought into life through a group of artist´s glance. Afterwards, we will test the analysis´s acquired knowledge, while extending the investigation to the feel of the common inhabitant (and no longer the expert^ artist) through the execution of three participative experiments conceived as qualitative field works. The results of both case study groups, will be compiled, organized and structured in a taxonomy of the inhabiting. This taxonomy is composed by forty seven parameters that explicitly state the complex nature of the XXI century home, regarded as a personal construct of every single inhabitant, as a process that happens through time and space and that entails the construction of the inhabitant. This wide taxonomy is organized regarding three spheres of the human being, In first place, those elements related to the way of “physically being” at home are expressed, including: the inhabitant its self, the house as architectural space and as materiality: objects, furniture, icons and symbols that fill the home. In second place, parameters related to the way of “perceiving“ are manifested; on the one hand, those that derive from what we see; on the other hand, those that derive from what we do not see, but feel. In third place, those factors deriving from the inhabitant as a home "creator/player" who is acting in the world and feeling the world while constructing it through a myriad of relationships he establishes with it. Finally, the investigation tries to reveal the synergies, connections and relations between all these elements extracted from the feelings of the common inhabitant, induced through the analysis and reinterpretation of the case studies, and therefore exposing a state of things belonging to western world at present.
