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.

The process framework comprises three phases, as follows: scope the supply chain/network; identify the options for supply system architecture and select supply system architecture. It facilitates a structured approach that analyses the supply chain/network contextual characteristics, in order to ensure alignment with the appropriate supply system architecture. The process framework was derived from comprehensive literature review and archival case study analysis. The review led to the classification of supply system architectures according to their orientation, whether integrated; partially integrated; co-ordinated or independent. The classification was combined with the characteristics that influence the selection of supply system architecture to encapsulate the conceptual framework. It builds upon existing frameworks and methodologies by focusing on structured procedure; supporting project management; facilitating participation and clarifying point of entry. The process framework was initially tested in three case study applications from the food, automobile and hand tool industries. A variety of industrial settings was chosen to illustrate transferability. The case study applications indicate that the process framework is a valid approach to the problem; however, further testing is required. In particular, the use of group support system technologies to support the process and the steps involving the participation of software vendors need further testing. However, the process framework can be followed due to the clarity of its presentation. It considers the issue of timing by including alternative decision-making techniques, dependent on the constraints. It is useful for ensuring a sound business case is developed, with supporting documentation and analysis that identifies the strategic and functional requirements of supply system architecture.

Nowadays, agri-food chains are more global than ever and are characterized by increased imports and exports and global sourcing of products, resulting in increased cross-border transaction risks. The objective of this paper is to identify the typical risks regarding agri-food supply chains involved in cross-border transactions and to assess their importance as perceived by agri-food managers. The analysis takes into consideration four different agrifood value chains (meat, grain, olive oil, fresh vegetables and fruits). Following an explorative approach and a qualitative technique, a series of face to face in-depth interviews was conducted. Results indicate that risk perception may be quite different across countries, value chains, tiers of the supply chain, as well as across respondents. The prevalence of Market dynamics risks was pointed out in most of the interviews, yielding the impression that many operators identify the market as the most difficult environment. Differences in risk perception between fresh produce (fruit/vegetables and meat) and processed food chains (grain and olive oil) are probably interrelated to the different degree of integration within these supply chains, the different level of standardization achieved and the different causes of risks that are inherent to the nature of the product.

This research aims at assessing the environmental impact of the poultry supply chain from cradle to grave using case study research and also life cycle assessment (LCA). While a limited number of generic poultry production LCA studies have been published, fewer yet assess the whole process of a specific organisation, none comparing the increased impact of further processing. Our results show that irrespectively of the impact assessment method utilised, the process of producing portions is considerably higher in total environmental impact due to the extra raw material required to produce the same mass into retail. Our research contributes to the growing number of LCA studies and could be used by practitioners for comparison against national and international averages. From a theoretical point of view, this research provides new insights into the relationship between vertically integrated supply chains and environmental performance which has not been examined in the past.

This research adds to a body of work exploring the role of Social Network Analysis (SNA) in the study of both relational and structural characteristics of supply chain networks. Two contrasting network cases (food enterprises and digital-based enterprises) are chosen in order to elicit structural differences in business networks subject to divergences in local embeddedness and the relative materiality of the goods and services produced. Our analysis and findings draw out differences in network structure as evidenced by metrics of network centralization and cohesion, the presence of components and other sub-groupings, and the position of central actors. We relate these structural features both to the nature of the networks and to the (qualitative) experiences of the actors themselves. We find, in particular, the role of customers as co-creators of knowledge (for the Food network), the central role of infrastructure and services (for the Digital network), the importance of ICT as a source of codified knowledge inputs, along with the continuing importance of geographical proximity for the development and transfer of tacit knowledge and for incremental learning.

A great deal of attention in the supply chain management literature is devoted to study material and demand information flows and their coordination. But in many situations, supply chains may convey information from different nature, they may be an important channel companies have to deliver knowledge, or specifically, technical information to the market. This paper studies the technical flow and highlights its particular requirements. Drawing upon a qualitative field research, it studies pharmaceutical companies, since those companies face a very specific challenge: consumers do not have discretion over their choices, ethical drugs must be prescribed by physicians to be bought and used by final consumers. Technical information flow is rich, and must be redundant and early delivered at multiple points. Thus, apart from the regular material channel where products and order information flow, those companies build a specialized information channel, developed to communicate to those who need it to create demand. Conclusions can be extended to supply chains where products and services are complex and decision makers must be clearly informed about technology-related information. (C) 2009 Elsevier B.V.

Objective: To illustrate methodological issues involved in estimating dietary trends in populations using data obtained from various sources in Australia in the 1980s and 1990s. Methods: Estimates of absolute and relative change in consumption of selected food items were calculated using national data published annually on the national food supply for 1982-83 to 1992-93 and responses to food frequency questions in two population based risk factor surveys in 1983 and 1994 in the Hunter Region of New South Wales, Australia. The validity of estimated food quantities obtained from these inexpensive sources at the beginning of the period was assessed by comparison with data from a national dietary survey conducted in 1983 using 24 h recall. Results: Trend estimates from the food supply data and risk factor survey data were in good agreement for increases in consumption of fresh fruit, vegetables and breakfast food and decreases in butter, margarine, sugar and alcohol. Estimates for trends in milk, eggs and bread consumption, however, were inconsistent. Conclusions: Both data sources can be used for monitoring progress towards national nutrition goals based on selected food items provided that some limitations are recognized. While data collection methods should be consistent over time they also need to allow for changes in the food supply (for example the introduction of new varieties such as low-fat dairy products). From time to time the trends derived from these inexpensive data sources should be compared with data derived from more detailed and quantitative estimates of dietary intake.

Purpose - The purpose of this paper is to document the outcome of a global three-year long supply chain improvement initiative at a multi-national producer of branded sporting goods that is transforming from a holding structure to an integrated company. The case company is comprised of seven internationally well-known sport brands, which form a diverse set of independent sub-cases, on which the same supply chain metrics and change project approach was applied to improve supply chain performance. Design/methodology/approach - By using in-depth case study and statistical analysis the paper analyzes across the brands how supply chain complexity (SKU count), supply chain type (make or buy) and seasonality affect completeness and punctuality of deliveries, and inventory as the change project progresses. Findings - Results show that reduction in supply chain complexity improves delivery performance, but has no impact on inventory. Supply chain type has no impact on service level, but brands with in-house production are better in improving inventory than those with outsourced production. Non-seasonal business units improve service faster than seasonal ones, yet there is no impact on inventory. Research limitations/implications - The longitudinal data used for the analysis is biased with the general business trend, yet the rich data from different cases and three-years of data collection enables generalizations to a certain level. Practical implications - The in-depth case study serves as an example for other companies on how to initiate a supply chain improvement project across business units with tangible results. Originality/value - The seven sub-cases with their different characteristics on which the same improvement initiative was applied sets a unique ground for longitudinal analysis to study supply chain complexity, type and seasonality.

The research performed a sustainability assessment of supply chains of the anchoveta (Engraulis ringens) in Peru. The corresponding fisheries lands 6.5 million t per year, of which <2% is rendered into products for direct human consumption (DHC) and 98% reduced into feed ingredients (fishmeal and fish oil, FMFO), for export. Several industries compete for the anchoveta resources, generating local and global impacts. The need for understanding these dynamics, towards sustainability-improving management and policy recommendations, determined the development of a sustainability assessment framework: 1) characterisation and modelling of the systems under study (with Life Cycle Assessment and other tools) including local aquaculture, 2) calculation of sustainability indicators (i.e. energy efficiency, nutritional value, socio-economic performances), and 3) sustainability comparison of supply chains; definition and comparison of alternative exploitation scenarios. Future exploitation scenarios were defined by combining an ecosystem and a material flow models: continuation of the status quo (Scenario 1), shift towards increased proportion of DHC production (Scenario 2), and radical reduction of the anchoveta harvest in order for other fish stocks to recover and be exploited for DHC (Scenario 3). Scenario 2 was identified as the most sustainable. Management and policy recommendations include improving of: controls for compliance with management measures, sanitary conditions for DHC, landing infrastructure for small- and medium-scale (SMS) fisheries; the development of a national refrigerated distribution chain; and the assignation of flexible tolerances for discards from different DHC processes.

The competitiveness of businesses is increasingly dependent on their electronic networks with customers, suppliers, and partners. While the strategic and operational impact of external integration and IOS adoption has been extensively studied, much less attention has been paid to the organizational and technical design of electronic relationships. The objective of our longitudinal research project is the development of a framework for understanding and explaining B2B integration. Drawing on existing literature and empirical cases we present a reference model (a classification scheme for B2B Integration). The reference model comprises technical, organizational, and institutional levels to reflect the multiple facets of B2B integration. In this paper we onvestigate the current state of electronic collaboration in global supply chains focussing on the technical view. Using an indepth case analysis we identify five integration scenarios. In the subsequent confirmatory phase of the research we analyse 112 real-world company cases to validate these five integration scenarios. Our research advances and deepens existing studies by developing a B2B reference model, which reflects the current state of practice and is independent of specific implementation technologies. In the next stage of the research the emerging reference model will be extended to create an assessment model for analysing the maturity level of a given company in a specific supply chain.

Biofuels are considered as a promising substitute for fossil fuels when considering the possible reduction of greenhouse gases emissions. However limiting their impacts on potential benefits for reducing climate change is shortsighted. Global sustainability assessments are necessary to determine the sustainability of supply chains. We propose a new global criterion based framework enabling a comprehensive international comparison of bioethanol supply chains. The interest of this framework is that the selection of the sustainability indicators is qualified on three criterions: relevance, reliability and adaptability to the local context. Sustainability issues have been handled along environmental, social and economical issues. This new framework has been applied for a specific issue: from a Swiss perspective, is locally produced bioethanol in Switzerland more sustainable than imported from Brazil? Thanks to this framework integrating local context in its indicator definition, Brazilian production of bioethanol is shown as energy efficient and economically interesting for Brazil. From a strictly economic point of view, bioethanol production within Switzerland is not justified for Swiss consumption and questionable for the environmental issue. The social dimension is delicate to assess due to the lack of reliable data and is strongly linked to the agricultural policy in both countries. There is a need of establishing minimum sustainability criteria for imported bioethanol to avoid unwanted negative or leakage effects.

Although gene by environment interactions may play a key role in the maintenance of genetic polymorphisms, little is known about the ecological factors involved in these interactions. We investigated whether food supply and parasites can mediate covariation between the degree of adult pheomelanin-based coloration, a heritable trait, and offspring body mass in the tawny owl (Strix aluco). We swapped clutches between nests to allocate genotypes randomly among environments. Three weeks after hatching, we challenged the immune system of 80 unrelated nestlings with either a phytohemagglutinin (PHA) or a lipopolysaccharide, surrogates of alternative parasites, and then fed them ad lib. or food-restricted them during the following 6 days in the laboratory. Whatever the immune challenge, nestlings fed ad lib. converted food more efficiently into body mass when their biological mother was dark pheomelanic. In contrast, food-restricted nestlings challenged with PHA lost less body mass when their biological mother was pale pheomelanic. Nestling tawny owls born from differently melanic mothers thus show differing reaction norms relative to food availability and parasitism. This suggests that dark and pale pheomelanic owls reflect alternative adaptations to food availability and parasites, factors known to vary in space and time.

Supply chains are becoming increasingly dependent on information ex-change in today’s world, and any disruption can cause severe repercus-sions to the flow of materials in the chain. The speed, accuracy and amount of information are key factors. The aim in this thesis is to address a gap in the research by focusing on information exchange and the risks related to it in a multimodal wood supply chain operating between the Baltic States and Finland. The study involved interviewing people engaged in logistics management in the supply chain in question. The main risk the interviewees identified arose from the sea logistics system, which held a lot of different kinds of information. The threat of breakdown in the Internet connection was also found to hinder the operations significantly. A vulnerability analysis was carried out in order to identify the main actors and channels of infor-mation flow in the supply chain. The analysis revealed that the most important and therefore most vulnerable information-exchange channels were those linking the terminal superintendent, the operative managers and the mill managers. The study gives a holistic picture of the investigated supply chain. Information-exchange-related risks varied greatly. One of the most frequently mentioned was the risk of information inaccuracy, which was usually due to the fact that those in charge of the various functions did not fully understand the consequences for the entire chain.

Nowadays the Western companies are considered responsible for the social and environmental issues in their whole supply chains. To influence the practices of their suppliers the Western companies have created suppliers codes of conduct (SCCs) which express their requirements. Suppliers’ compliance with the SCCs is checked through audits. The purpose of this thesis is to analyze SCCs as a means for Western companies to ensure socially and environmentally responsible actions in their global supply chains, and the sub-objectives are to find out 1) how well do the SCCs and their auditing work at suppliers’ production sites and 2) how can possible problems related to SCCs and their auditing be solved. This is a qualitative research carried out in the form of a case study with two case companies. In this study both primary and secondary data is used. The primary data is collected in the form of interviews of the case company representatives and three external experts. Based on a theoretical framework of previous research in the fields of corporate social responsibility and supply chain management, a model with eleven factors, which influence the success of SCC implementation and the auditing of SCC –implementation, is drafted. Also several different best-practices to help to solve and avoid possible problems related to SCC -implementation and auditing have been identified from previous research. Based on the findings of this study the theoretical model has been updated adding two new influential factors. It seems that how well the SCC and its auditing work at suppliers’ production sites depends on the joint effect of thirteen influential factors: buyer’s purchasing policy, supplier’s motivation, buyer’s commitment, the solving of agency problems, the contents of the SCC, supplier’s role and the buyer-supplier –relationship, complexity of supply chain, the limitations of the smaller buyers, cooperation through a business association or multi-stakeholder system, the role of supplier’s employees, SCC –related communication and supplier’s understanding, cheating in audits and the auditors. The possible problems related to SCCs and their auditing can be solved by adopting best-practices. Nine of the theoretical best-practices stand out from the findings of this study: 1) two-way communication and collecting feedback from suppliers, 2) the philosophy of continuous improvement, 3) long-term business relationships with the supplier, 4) informing the supplier about the advantages of SCC –compliance, 5) rewarding code-compliant suppliers, 6) building collaborative, good buyer-supplier relationships, 7) supporting and advising the supplier, 8) joining a business association or multi-stakeholder system and 9) interviewing supplier’s employees as a part of the audits.
