Sustainability study of nanomaterials including societal and occupational implications

In recent years there has been a tremendous amount of research in the area of nanotechnology. History tells us that the commercialization of technologies will always be accompanied by both positive and negative effects for society and the environment. Products containing nanomaterials are already available in the market, and yet there is still not much information regarding the potential negative effects that these products may cause. The work presented in this dissertation describes a holistic approach to address different dimensions of nanotechnology sustainability. Life cycle analysis (LCA) was used to study the potential usage of polyethylene filled with nanomaterials to manufacture automobile body panels. Results showed that the nanocomposite does not provide an environmental benefit over traditional steel panels. A new methodology based on design of experiments (DOE) techniques, coupled with LCA, was implemented to investigate the impact of inventory uncertainties. Results showed that data variability does not have a significant effect on the prediction of the environmental impacts. Material profiles for input materials did have a highly significant effect on the overall impact. Energy consumption and material characterization were identified as two mainstreams where additional research is needed in order to predict the overall impact of nanomaterials more effectively. A study was undertaken to gain insights into the behavior of small particles in contact with a surface exposed to air flow to determine particle lift-off from the surface. A mapping strategy was implemented that allows for the identification of conditions for particle liftoff based on particle size and separation distance from the wall. Main results showed that particles smaller than 0:1mm will not become airborne under shear flow unless the separation distance is greater than 15 nm. Results may be used to minimize exposure to airborne materials. Societal implications that may occur in the workplace were researched. This research task explored different topics including health, ethics, and worker perception with the aim of identifying the base knowledge available in the literature. Recommendations are given for different scenarios to describe how workers and employers could minimize the unwanted effects of nanotechnology production.

Business and Public–Private Partnerships for Sustainability: Beyond Corporate Social Responsibility?

This article analyses public–private partnerships (PPPs) in the field of sustainable development from an international relations perspective with insights from the business and ethics literature. We argue that the role of business in these types of arrangements has not been sufficiently explored. After presenting three ways of approaching PPPs to stress the many facets of partnerships across the public–private divide, we discuss the emergence of these novel forms of governance from a demand side and contrast such a functionalist reading with the supply side. Then we look at the micro-economic incentives for corporations to engage in such endeavours. We develop arguments derived from the dominant literature to provide an analytical framework for explaining business participation. Finally, we discuss the role of PPPs in light of input and output legitimacy. We conclude by alluding to the emergence of an expectation-capacity gap and normative issues related to the global PPP architecture.

Older patients with chronic myeloid leukemia (≥65 years) profit more from higher imatinib doses than younger patients: a subanalysis of the randomized CML-Study IV

The impact of imatinib dose on response rates and survival in older patients with chronic myeloid leukemia in chronic phase has not been studied well. We analyzed data from the German CML-Study IV, a randomized five-arm treatment optimization study in newly diagnosed BCR-ABL-positive chronic myeloid leukemia in chronic phase. Patients randomized to imatinib 400 mg/day (IM400) or imatinib 800 mg/day (IM800) and stratified according to age (≥65 years vs. <65 years) were compared regarding dose, response, adverse events, rates of progression, and survival. The full 800 mg dose was given after a 6-week run-in period with imatinib 400 mg/day. The dose could then be reduced according to tolerability. A total of 828 patients were randomized to IM400 or IM800. Seven hundred eighty-four patients were evaluable (IM400, 382; IM800, 402). One hundred ten patients (29 %) on IM400 and 83 (21 %) on IM800 were ≥65 years. The median dose per day was lower for patients ≥65 years on IM800, with the highest median dose in the first year (466 mg/day for patients ≥65 years vs. 630 mg/day for patients <65 years). Older patients on IM800 achieved major molecular remission and deep molecular remission as fast as younger patients, in contrast to standard dose imatinib with which older patients achieved remissions much later than younger patients. Grades 3 and 4 adverse events were similar in both age groups. Five-year relative survival for older patients was comparable to that of younger patients. We suggest that the optimal dose for older patients is higher than 400 mg/day. ClinicalTrials.gov identifier: NCT00055874

“Se querem que façamos algo pela floresta tem que nos pagar”: As lógicas da participação dos camponeses nos Comités de Gestão dos Recursos Naturais nos distritos de Palma e Mocimboa da Praia em 2009: Relatório do trabalho de campo em Namiune, Nkonga e 5º Congresso, Maputo, Dezembro de 2010

Our study considers the natural resources of the Miombo forests in Cabo Delgado from a broad ecosystems perspective. Thus, our view goes beyond the disciplinary approaches of forestry, agronomy, biology or zoology, and also of the social sciences, namely anthropology, history, sociology, political science or economics. The present study aims to establish a dialogue and create synergies between Miti Ltd. – the logging company and owner of the forest concessions – as well as government and state structures at the various levels and the communities – through the Committees on Natural Resources – in order to promote the sustainable use of resources and ecosystems. The research methodology we used can broadly be described as moderated transdisciplinary interaction for action-research based on the approach known as Learning for Sustainability (LforS, http://www.cde.unibe.ch/Pages/Project/2/14/Learning-for-Sustainability-Extension-Approach.aspx). The research methods used include: LforS seminars; field work; forests observations focusing, among others, on ecosystems, trees, wildlife, and burned areas; visits to farms; and interviews. We conducted both collective interviews and individual interviews, including with key informants. The main results indicate that members of the Committee on Natural Resources have a dual attitude: their statements defend the paradigm of sustainable use of natural resources as well as their own immediate monetary gain. They are willing to apply the values, concepts and theories of sustainable development that underpin the establishment of Committees on Natural Resources if they are paid for their work or if they can derive direct benefits from it, i.e. if they can earn a salary or allowance. If this does not happen, however, they are willing to allow actors to engage in illegal hunting or logging activities. This dual attitude also exists in relation to forestry operators. If the concession workers pay the committee members in cash or provide goods, they can run their business even if they violate the law. Natural forest regeneration in Nkonga and Namiune already shows the impact of such use. Although there are many saplings that could basically ensure continuous regeneration under sustainable management, repeated burning is damaging the young trees, deforming them and killing a great number of them. Campaigns against uncontrolled fires are ineffective because the administrative and political authorities have a dual attitude as well and are also part of the group that uses resources to their own profit and benefit. There are institutional structures within the administration, populations, and communities to perform regulating functions, create and implement rules, punish offenders, and oversee resource use. However, they feel that since they are not paid for performing these functions, they do not have to do so. This attitude shows a lack of awareness, but also indicates a situation where everyone seeks to derive maximum benefits from existing resource use patterns. Anything goes.

Coupled human and natural system dynamics as key to the sustainability of Lake Victoria's ecosystem services

East Africa’s Lake Victoria provides resources and services to millions of people on the lake’s shores and abroad. In particular, the lake’s fisheries are an important source of protein, employment, and international economic connections for the whole region. Nonetheless, stock dynamics are poorly understood and currently unpredictable. Furthermore, fishery dynamics are intricately connected to other supporting services of the lake as well as to lakeshore societies and economies. Much research has been carried out piecemeal on different aspects of Lake Victoria’s system; e.g., societies, biodiversity, fisheries, and eutrophication. However, to disentangle drivers and dynamics of change in this complex system, we need to put these pieces together and analyze the system as a whole. We did so by first building a qualitative model of the lake’s social-ecological system. We then investigated the model system through a qualitative loop analysis, and finally examined effects of changes on the system state and structure. The model and its contextual analysis allowed us to investigate system-wide chain reactions resulting from disturbances. Importantly, we built a tool that can be used to analyze the cascading effects of management options and establish the requirements for their success. We found that high connectedness of the system at the exploitation level, through fisheries having multiple target stocks, can increase the stocks’ vulnerability to exploitation but reduce society’s vulnerability to variability in individual stocks. We describe how there are multiple pathways to any change in the system, which makes it difficult to identify the root cause of changes but also broadens the management toolkit. Also, we illustrate how nutrient enrichment is not a self-regulating process, and that explicit management is necessary to halt or reverse eutrophication. This model is simple and usable to assess system-wide effects of management policies, and can serve as a paving stone for future quantitative analyses of system dynamics at local scales.

Environmental sustainability and the human element: Decision making in National Cancer Institute-designated cancer centers and Practice Greenhealth subscribing institutions

Background. Various aspects of sustainability have taken root in the hospital environment; however, decisions to pursue sustainable practices within the framework of a master plan are not fully developed in National Cancer Institute (NCI) -designated cancer centers and subscribing institutions to the Practice Greenhealth (PGH) listserv.^ Methods. This cross sectional study was designed to identify the organizational characteristics each study group pursed to implement sustainability practices, describe the barriers they encountered and reasons behind their choices for undertaking certain sustainability practices. A web-based questionnaire was pilot tested, and then sent out to 64 NCI-designated cancer centers and 1638 subscribing institutions to the PGH listserv.^ Results. Complete responses were received from 39 NCI-designated cancer centers and 58 subscribing institutions to the PGH listserv. NCI-designated cancer centers reported greater progress in integrating sustainability criteria into design and construction projects than hospitals of institutions subscribing to the PHG listserv (p-value = <0.05). Statistically significant differences were also identified between these two study groups in undertaking work life options, conducting energy usage assessments, developing energy conservation and optimization plans, implementing solid waste and hazardous waste minimization programs, using energy efficient vehicles and reporting sustainability progress to external stakeholders. NCI-designated cancer centers were further along in implementing these programs (p-value = <0.05). In comparing the self-identified NCI-designated cancer centers to centers that indicated they were both and NCI and PGH, the later had made greater progress in using their collective buying power to pursue sustainable purchasing practices within the medical community (p-value = <0.05). In both study groups, recycling programs were well developed.^ Conclusions. Employee involvement was viewed as the most important reason for both study groups to pursue recycling initiatives and incorporated environmental criteria into purchasing decisions. A written sustainability commitment did not readily translate into a high percentage that had developed a sustainability master plan. Coordination of sustainability programs through a designated sustainability professional was not being undertaken by a large number of institutions within each study group. This may be due to the current economic downturn or management's attention to the emerging health care legislation being debated in congress. ^ Lifecycle assessments, an element of a carbon footprint, are seen as emerging areas of opportunity for health care institutions that can be used to evaluate the total lifecycle costs of products and services.^

Efficiency from pharmacy inventory technology: A means to improving quality in non-profit hospitals

Hospitals, like all organizations, have both a mission and a finite supply of resources with which to accomplish that mission. Because the inventory of therapeutic drugs is among the more expensive resources needed by a hospital to achieve its mission, a conceptual model of structure plus process equals outcome posits that adequate emphasis should be placed on optimization of the organization's investment in this important structural resource to provide highest quality outcomes. Therefore emphasis should be placed on the optimization of pharmacy inventory because lowering the financial investment in drug inventory and associated costs increases productive efficiency, a key element of quality. ^ In this study, a post-intervention analysis of a hospital pharmacy inventory management technology implementation at The University of Texas M.D. Anderson Cancer Center was conducted to determine if an intervention which reduced a hospital's financial investment in pharmaceutical inventory provided an opportunity to incrementally optimize the organization's mix of structural resources thereby improving quality of care. The results suggest that hospital pharmacies currently lacking technology to support automated purchasing logistics and perpetual, real-time inventory management for drugs may achieve measurable benefits from the careful implementation of such technology, enabling the hospital to lower its investment in on-hand inventory and, potentially, to reduce overall purchasing expenditures. ^ The importance of these savings to the hospital and potentially to the patient should not be underestimated for their ability to generate funding for previously unfunded public health programs or in their ability to provide financial relief to patients in the form of lower drug costs given the current climate of escalating healthcare costs and tightening reimbursements.^

Las decisiones de proyecto y los costes de construcción en la vivienda rural, aplicado al estudio de la vivienda autopromovida en la provincia de Cáceres

En la coyuntura actual, en la que existe por un lado, exceso en la oferta de vivienda (de alto precio o de segunda residencia), y aparece por otro demanda de vivienda (de bajo precio y/o social), el mercado inmobiliario se encuentra paradójicamente bloqueado. Así, surge esta investigación como fruto de este momento histórico, en el cual se somete a debate económico el producto vivienda, no solo como consecuencia de la profunda crisis económica, sino también para la correcta gestión de los recursos desde el punto de vista de lo eficiente y sostenible. Se parte de la hipótesis de que es necesario determinar un estimador de costes de construcción de vivienda autopromovida como una de las soluciones a la habitación en el medio rural de Extremadura, para lo cual se ha tomado como modelo de análisis concretamente la Vivienda Autopromovida subvencionada por la Junta de Extremadura en el marco de la provincia de Cáceres. Con esta investigación se pretende establecer una herramienta matemática precisa que permita determinar la inversión a los promotores, el posible margen de beneficios a los contratistas y el valor real de la garantía en el préstamo a las entidades financieras. Pero el objetivo de mayor proyección social de esta investigación consiste en facilitar una herramienta sencilla a la Junta de Extremadura para que pueda establecer las ayudas de una manera proporcional. De este modo se ayuda a optimizar los recursos, lo cual en época de crisis resulta aun más acuciante, ya que conociendo previamente y con bastante exactitud el importe de las obras se pueden dirigir las ayudas de forma proporcional a las necesidades reales de la ejecución. De hecho, ciertas características difíciles de cuantificar para determinar las ayudas en materia de vivienda, como la influencia del número de miembros familiares o la atención a la discapacidad, se verían contempladas de forma indirecta en el coste estimado con el método aquí propuesto, ya que suponen siempre un aumento de las superficies construidas y útiles, de los huecos de fachadas o del tamaño de locales húmedos y por tanto se contemplan en la ecuación del modelo determinado. Por último, contar con un estimador de costes potencia la forma de asentamiento de la construcción mediante autopromocion de viviendas ya que ayuda a la toma de decisiones al particular, subvencionado o no. En efecto, la herramienta es valida en cierta medida para cualquier autopromocion, constituye un sistema de construcción con las menores posibilidades especulativas y lo más sostenible, es abundante en toda Extremadura, y consigue que el sector de la construcción sea un sistema más eficiente al optimizar su proceso económico de producción. SUMMARY Under the present circumstances, in which there is, on one hand, an excess in the supply of housing (high-price or second-home), and on the other hand a demand for housing (low cost and/or social), paradoxically the property market is at a standstill. This research has come about as a result of this moment in time, in which the product: housing, is undergoing economic debate, not only on account of this serious economic crisis, but for the proper management of resources from the point of view of efficiency and sustainability. A building-costs estimator for owner-developed housing is deemed necessary as one of the solutions for the rural environment that is Extremadura. To this end, it is the Owner-Developed House which has been taken as analysis model. It is subsidized by the Extremadura Regional Government in Caceres Province. This research establishes an accurate mathematical tool to work out the developers’ investment, the builder’s potential profit margin and the reality of the loan for the Financial Institution. But the result of most social relevance in this research is to provide the Extremadura Regional Government with a simple tool, so that it can draw up the Subventions proportionally. Thus, the resources are optimized, an even more vital matter in times of economic slump, due to the fact that if the cost of the building works is known with some accuracy beforehand, the subventions can be allocated in a way that is proportional to the real needs of execution. In fact certain elements related to housing subventions which are hard to quantify, such as the influence of number of family members or disability support, would be covered indirectly in cost estimate with the proposed method, since they inevitably involve an increase in built area, exterior wall openings and the size of plumbed rooms. As such they are covered in the determined model equation. Lastly, the availability of a cost-estimator reinforces the ownerdeveloped building model, since it assists decision-making by the individual, whether subsidized or not. This is because the tool is valid to some extent in any owner-development, and this building scheme, which is common in Extremadura, is the most sustainable, and the least liable to speculation. It makes the building sector more efficient by optimizing the economic production process.

Intereses exógenos y resistencia ciudadana en la transformación físicosocial de un asentamiento auto-producido de Dakar (2005-2011)

La presión sobre el acceso a la tierra en la península de Dakar, Senegal, ha generado un proceso de transformación físico-social del mayor asentamiento auto-producido de la periferia urbana de Dakar (Pikine Irregular Sur) en el periodo 2005-2011. Esta investigación se propone analizar en qué medida las acciones llevadas a cabo: i) satisfacen o no el sistema integral de necesidades de los afectados (Demanda); ii) favorecen la implicación de los afectados o, por el contrario, fortalecen las estructuras de poder dominantes (Oferta), y iii) promueven o no la autonomía económica, la sostenibilidad ambiental, la equidad social y la legitimidad de los actores que participan (Entorno). La investigación se ha llevado a cabo por el método de estudio de casos, mediante un proceso de recogida de información participativo, articulado de abajo hacia arriba, en el que han participado 196 personas; la información recogida se ha procesado mediante la utilización de dos herramientas de análisis de realidades complejas: flujo de programa y sistema funcional. Los resultados del estudio de los casos 1 y 2 muestran que las acciones se han llevado a cabo en beneficio de los intereses de los mercados y de los actores que toman las decisiones y gestionan los recursos, incrementando la dependencia económica, empobreciendo a los directamente afectados y fragmentando su tejido social, promoviendo un desarrollo urbano desequilibrado, disperso y segregado, y deslegitimando a las instituciones involucradas. En el estudio del caso 3, en cambio, se verifica que la acción se ha llevado a cabo en beneficio de los intereses de los directamente afectados, utilizando recursos endógenos, fortaleciendo su tejido social, promoviendo un desarrollo urbano concentrado e inclusivo, e incrementando la legitimidad de las instituciones involucradas. El análisis cruzado de los resultados muestra que la pobreza, la exclusión social y la precariedad habitacional, en el contexto específico de la periferia de Dakar, no son un problema de falta de recursos, sino de falta de ética por parte de quienes gestionan y financian los procesos de transformación físico-social, y de falta de voluntad por parte de las autoridades de implicar a los ciudadanos, y en particular a los directamente afectados, en los procesos de toma de decisiones de las acciones y los programas que les afectan. Finalmente se concluye que no se trata de luchar contra la pobreza, sino de luchar contra los sistemas injustos que generan la pobreza y la exclusión. ABSTRACT The pressure on the access to land in the area of Dakar, Senegal, has generated a physical/social transformation process in the largest self-produced settlement in the urban periphery of Dakar (South Irregular Pikine), in the period 2005-2011. This research aims to analyze to what extent the actions carried out: i) satisfy the integral needs of the affected population (Demand), ii) encourage the involvement of those affected or otherwise strengthen dominant power structures (Supply), and iii) promote or inhibit economic autonomy, environmental sustainability, social equity and legitimacy of the actors involved (Environment). The research was conducted by the case study method. 196 people participated in a bottom-up participatory process of information gathering. The information collected was processed using two custom tools aimed to analyse complex systems: the program flow and the functional system. The results of case studies 1 and 2 show that the actions were carried out in the best interest of the markets and the actors who made decisions and managed resources, increasing economic dependence, impoverishing those directly affected and fragmenting their social network by promoting an unbalanced, dispersed and segregated urban development, and de-legitimizing the institutions involved in the process. On the contrary, in the case study 3 it is verified that the action has been carried out on behalf of the interests of those directly affected, using endogenous resources, strengthening the social network, promoting a focused and inclusive urban development, and increasing legitimacy of the institutions involved. The comparative analysis of the results shows that poverty, social exclusion and precarious housing in South Irregular Pikine are not a problem of lack of resources but of unethical behaviour of those who manage and finance physical and social transformation processes, as well as unwillingness on the part of the authorities to involve citizens in the decision making processes for the actions and programs that affect them. Finally we conclude that the enemy to fight against is not poverty but unfair systems that generate poverty and exclusion. RÉSUMÉ La pression sur le foncier dans la presqu'île de Dakar, au Sénégal, a généré un processus de transformation physico-sociale du plus grand établissement auto-produit de la périphérie urbaine de Dakar (Pikine Irrégulier Sud), durant la période 2005-2011. Cette recherche vise à analyser dans quelle mesure les actions menées: i) répondent ou non à l’ensemble des besoins intégrales des personnes concernés (Demande), ii) encouragent l'implication des concernées ou au contraire renforcent les structures de pouvoir dominant (Offre), et iii) favorisent ou non l'autonomie économique, la durabilité environnementale, l'équité sociale et la légitimité des acteurs concernés (Contexte). La recherche a été menée par la méthode des études de cas, par un processus de collecte d'information participative articulée du bas vers le haut dans lequel ont participé 196 personnes. Les informations recueillies ont été traitées à l'aide de deux outils d'analyse de réalités complexes: le système fonctionnel et le flux de programme. Les résultats de l'étude de cas 1 et 2 montrent que les actions ont été menées au profit des intérêts des marchés et des acteurs qui prennent les décisions et gèrent les ressources, augmentant la dépendance économique, appauvrissant ceux qui sont directement concernés et fragmentant leur tissu social, encourageant un développement urbain déséquilibré, dispersé et ségrégé, et délégitimant les institutions concernées. Dans l'étude de cas 3, cependant, il est vérifié que l'action a été menée au profit des intérêts de ceux qui sont directement concernés, en utilisant des ressources endogènes, en renforçant son tissu social, en encourageant un développement urbain concentré et inclusif, et en augmentant la légitimité des institutions concernées. L'analyse comparée des résultats montre que la pauvreté, l'exclusion sociale et le logement précaire, dans le contexte spécifique de la banlieue de Dakar, ne sont pas un problème de manque de ressources, mais de manque d'éthique de la part de ceux qui gèrent et financent les processus de transformation physico-sociale, et de manque de volonté de la part des autorités d'impliquer les citoyens, en particulier ceux qui sont directement concernés, dans le processus de prise de décision des actions et des programmes qui les impliquent. Finalement, on conclut qu'il ne s'agit pas de lutter contre la pauvreté, mais de lutter contre les systèmes injustes qui produisent la pauvreté et l'exclusion.

Indicators of sustainability of agriculture and livestock in Spain - Indicadores de sostenibilidad de la agricultura y ganadería española

Sustainability is an adjective used to characterize agriculture according to the degree of fulfillment of goals. Those goals are related to agro-ecological, environmental and socio-economic dimensions. Sustainability is a dynamic and temporal character. In absolute terms there is not an ending value because it changes as its dimensions make it. Spain is one of the main agricultural countries of the European Union both in terms of crop land and value of productions. The object of this study is to present a methodology of sustainability account to be incorporated into national statistical and to assess their performance in the course of the years. For that reason the data sources used have been the statistics of the Department of Agriculture and from others database. We presented a set of indicators of sustainability and its evaluation in a time series of at least 30 years. The trend analysis offers the evolution of the numerical values of the indicators in terms of efficiency, physical units used for a unit of product or its value in euros. The analyzed crops have been: wheat, barley, maize, sunflower, sugar beet, wine grape, olive oil, citrus, melon and tomato. Physical indicators were: land, water, energy, erosion, soil organic matter, and carbon balance; socio-economic indicators were: agricultural final production, prices, income, employment and use of fertilizers. In general, all crops increased their productive efficiency, higher in irrigated than on dry land. Spanish agricultural carbon sequestration capacity has multiplied by five in the last seventy years, as a result of the increase in the productivity of crops, in terms of total biomass and the modification of the soil management techniques. Livestock sector presents data of pork, broilers and laying hen. Those showed an improvement in efficiency and economic indicators. Overall we can say that Spanish agriculture and livestock subsector have a tendency towards sustainability, being its main threats extreme meteorological factors and the instability of todays markets.

How Can Local Manufacturing Improve Economic Sustainability? Saint Brissant: a case study of local manufacturing in Spain

Fast-fashion retailers and mass production dominate the fashion and apparel industry. Increased globalization, labor intensity and outsourcing to developing countries are fostering the interest in sustainability within the industry. There is a growth of a new movement attempting to offset the demand for fast fashion, "Slow Fashion" movement. Slow fashion is not time-based but quality-based approach in which designers, buyers, retailers and consumers are more aware of the impacts on workers, communities and ecosystems (Fletcher 2007). European Union has also some critical targets to reach by 2020. Spain, specifically, has to meet some requirements in terms of economy and sustainability. This exploratory study analyzed how slow fashion concept, precisely manufacturing locally, could improve economic development. Local manufacturing, its impact on economic development and the challenges of Spanish market are illustrated through a case study of one Spanish fashion brand, Saint Brissant.

Slow fashion and sustainability in Spain: How can local manufacturing improve sustainability and how do consumers respond?

"Slow Fashion" attempts to offset the demand for fast fashion and mass production (Fletcher, 2007). Consumers' response to sustainability-based practices is a limited discourse and studies for slow fashion concept are scarce. This study thus aims to enlighten the subject of how slow fashion concept could improve local economies and how Spanish consumers respond to such initiatives. This paper is based on an exploratory qualitative research for which focus group interviews including three group discussions with Spanish consumers were held. The data was examined by constant comparison analysis to present consumer insights. Moreover, a case study was conducted with a Spanish apparel brand. Saint Brissant was chosen since it manufactures in Spain to (i) ensure its products? high quality and (ii) to empower Spanish economy. This paper provides empirical insights. Even though local manufacturing was perceived to have a higher quality, Spanish consumers? behavioural intentions of using local brands were not high.Self-interest, mainly price and design, was recorded as the most influential purchase criteria. Furthermore, Saint Brissant case demonstrated that local manufacturing could boost local economies by creating workforce. However, governmental subsidies should be rearranged and consumers? perceptions should be improved to support local manufacturers in Spain.

New agri-environmental policies for the sustainability of mountainous olive farming. Evidences from Andalusia, Spain

La sostenibilidad de los sistemas olivareros situados en zonas de pendiente y montaña (SMOPS) en Andalucía se encuentra actualmente amenazada por las elevadas tasas de abandono que afectan a estos sistemas productivos. Así, la consumación de este proceso de abandono, no sólo pondría en peligro a las propias explotaciones, sino a todo el conjunto de bienes y servicios no productivos y al patrimonio cultural generado por este sistema productivo. En este contexto, la búsqueda de alternativas políticas enfocadas a revertir este proceso se erige como una necesidad categórica en aras de garantizar en el largo plazo la sostenibilidad de los olivares de montaña. Esta tesis pretende hacer frente a esta necesidad a través de la construcción de un marco político alternativo para los SMOPS, que permita la integración simultánea de todas las dimensiones que pueden influir en su desarrollo; esto es: el marco político actual, principalmente determinado por la Política Agraria Común (PAC) de la Unión Europea (UE); las preferencias de la sociedad hacia la oferta de bienes y servicios públicos generados por los SMOPS; y las preferencias y voluntad de innovación hacia nuevos manejos y sistemas de gestión de los agricultores y propietarios de las explotaciones. Para ello, se emplea una metodología de investigación mixta, que abarca la realización de cuatro encuestas (personales y online) llevadas a cabo a los agentes o grupos de interés involucrados directa o indirectamente en la gestión de los SMOPS –ciudadanos, agricultores y propietarios y expertos-; una profunda revisión de las herramientas de política agroambiental actuales y posibles alternativas a las mismas; y el desarrollo de nuevas estrategias metodológicas para dotar de mayor precisión y fiabilidad las estimaciones obtenidas a partir del Método del Experimento de Elección (MEE) en el campo de la valoración medioambiental. En general, los resultados muestran que una estrategia de política agroambiental basada en la combinación de los Contratos Territoriales de Zona Rural (CTZR) y el manejo ecológico supondría una mejora en la sostenibilidad de los sistemas olivareros de montaña andaluces, que, al mismo tiempo, propiciaría una mejor consideración de las necesidades y demandas de los agentes implicados en su gestión. Asimismo, los hallazgos obtenidos en esta investigación demandan un cambio de paradigma en los actuales pagos agroambientales, que han de pasar de una estrategia basada en la implementación de acciones, a otra enfocada al logro de objetivos, la cual, en el caso del olivar, se podría centrar en el aumento del secuestro de carbono en el suelo. Desde un punto de vista metodológico, los resultados han contribuido notablemente a mejorar la fiabilidad y precisión de las conclusiones estimadas a partir del MEE, mediante el diseño de un novedoso proceso iterativo para detectar posibles comportamientos inconsistentes por parte de los entrevistados con respecto a su máxima Disposición al Pago (DAP) para lograr la situación considerada como “óptima” en los olivares ecológicos de montaña andaluces. En líneas generales, el actual marco institucional favorece la puesta en práctica de la mayoría de las estrategias propuestas en esta tesis; sin embargo son necesarios mayores esfuerzos para reconducir los actuales Pagos Agroambientales y Climáticos de la PAC, hacia una estrategia de política agroambiental adaptada a las necesidades y requisitos del territorio en el que se aplica, enfocada al logro de objetivos y que sea capaz de integrar y coordinar al conjunto de agentes y grupos de interés involucrados -directa o indirectamente- en la gestión de los olivares de montaña. En este contexto, se espera que la puesta en práctica de nuevas estructuras y acuerdos de gobernanza territorial juegue un importante papel en el desarrollo de una política agroambiental realmente adaptada a las necesidades de los sistemas olivareros de montaña andaluces. ABSTRACT The long-term sustainability of Andalusian sloping and mountainous olive production systems (SMOPS) is currently threatened by the high abandonment rates that affect these production systems. The effective occurrence of this abandonment process is indeed menacing not only farms themselves, but also the wide array of public goods and services provided by SMOPS and the cultural heritage held by this production system. The search of policy alternatives aimed at tackling this process is thus a central necessity. This thesis aims to undertake this necessity by building an alternative policy framework for SMOPS that simultaneously integrates the several dimensions that are susceptible to influence it, namely: the current policy framework, mainly determined by the European Union’s (EU) Common Agricultural Policy (CAP); the social preferences toward the supply of SMOPS’ public goods and services; and farmers’ preferences and willingness to innovate toward new management practices in their farms. For this purpose, we put into practice a mixed-method strategy that combines four face-to-face and online surveys carried out with SMOPS’ stakeholders -including citizens, farmers and experts-; in-depth analysis of current and alternative agrienvironmental policy (AEP) instruments; and the development of novel methodological approaches to advance toward more reliable Discrete Choice Experiment’s (DCE) outcomes in the field of environmental valuation. Overall, results show that a policy strategy based on the combination of Territorial Management Contracts (TMC) and organic management would further enhance Andalusian SMOPS’ sustainability by simultaneously taking into account stakeholders’ demands and needs. Findings also call for paradigm shift of the current action-oriented design of Agri-Environmental-Climate Schemes (AECS), toward a result-based approach, that in the case of olive orchards should particularly be focused on enhancing soil carbon sequestration. From a methodological perspective, results have contributed to improve the accuracy and feasibility of DCE outcomes by designing a novel and iterative procedure focused in ascertaining respondents’ inconsistent behaviour with respect to their stated maximum WTP for the attainment of an ideal situation to be achieved in organic Andalusian SMOPS. Generally, the present institutional framework favours the implementation of the main policy strategies proposed in this thesis, albeit further efforts are required to better conduct current CAP’s agri-environmental instruments toward a territorially targeted result-oriented strategy capable to integrate and coordinate the whole set of stakeholders involved in the management of SMOPS. In this regard, alternative governance structures and arrangements are expected to play a major role on the process of tackling SMOPS’ agri-environmental policy challenge.

Evaluating sustainability and food security of peasant farming systems in Mesoamerican highlands

En las últimas décadas, la agricultura sostenible ha sido objeto de gran interés y debate académico, no sólo en términos conceptuales, sino también en términos metodológicos. La persistencia de la inseguridad alimentaria y el deterioro de los recursos naturales en muchas regiones del mundo, ha provocado el surgimiento de numerosas iniciativas centradas en revitalizar la agricultura campesina así como renovadas discusiones sobre el rol que juega la agricultura como motor de desarrollo y principal actividad para alivio de la pobreza. Por ello, cuando hablamos de evaluar sistemas campesinos de montaña, debemos considerar tanto la dimensión alimentaria como las especificidades propias de los sistemas montañosos como base fundamental de la sostenibilidad. Al evaluar la contribución que han hecho alternativas tecnológicas y de manejo en la mejora de la sostenibilidad y la seguridad alimentaria de los sistemas campesinos de montaña en Mesoamérica, surgen tres preguntas de investigación: • ¿Se está evaluando la sostenibilidad de los sistemas campesinos teniendo en cuenta la variabilidad climática, la participación de los agricultores y las dinámicas temporales? • ¿Podemos rescatar tendencias comunes en estos sistemas y extrapolar los resultados a otras zonas? • ¿Son inequívocamente positivas las alternativas propuestas que se han llevado a cabo? En este trabajo se presentan tres evaluaciones de sostenibilidad que tratan de poner de manifiesto cuáles son los retos y oportunidades que enfrentan actualmente los sistemas campesinos de montaña. En primer lugar, se evalúan tres sistemas de manejo agrícola bajo dos años meteorológicamente contrastantes. Se determinó que durante el año que experimentó lluvias abundantes y temperaturas moderadas, los sistemas de bajos insumos, basados en el uso de abonos orgánicos y rotación de cultivos, obtuvieron los mejores resultados en indicadores ecológicos y similares resultados en los económicos y sociales que el sistema de altos insumos químicos. En el segundo año, con heladas tempranas y sequía invernal, la productividad se redujo para todos los sistemas pero los sistemas más diversificados (en variedades de maíz y/o siembra de otros cultivos) pudieron resistir mejor los contratiempos climáticos. En segundo lugar, se evalúa el grado de conocimiento (percepción) campesino para determinar los factores claves que determinan la sostenibilidad de sus sistemas y su seguridad alimentaria. Se determinó que los principales puntos críticos identificados por los campesinos (tamaño de parcela y pendiente del terreno) afectan de forma significativa a cuestiones de índole económica, pero no son capaces de explicar los desequilibrios alimenticios existentes. Realizando un análisis comparativo entre comunidades que presentaban buenos y malos resultados en cuanto a aporte energético y proteico, se determinó que la seguridad alimentaria estaba relacionada con la sostenibilidad de los sistemas y que concretamente estaba ligada a los atributos de equidad y autonomía. Otro resultado destacable fue que las comunidades más marginales y con mayor dificultad de acceso mostraron mayores niveles de inseguridad alimentaria, pero la variabilidad intergrupal fue muy alta. Eso demuestra que la seguridad alimentaria y nutricional forma parte de un complejo sistema de estrategias de autoabastecimiento ligada a la idiosincrasia misma de cada uno de los hogares. En tercer lugar, se evaluó el desempeño de las escuelas de campo de agricultores (ECAs) en la mejora de la sostenibilidad y la seguridad alimentaria de un sistema campesino de montaña. Para ver el efecto del impacto de estas metodologías a largo plazo, se estudiaron tres comunidades donde se habían implementado ECAs hace 8, 5 y 3 años. Encontramos que el impacto fue progresivo ya que fue la comunidad más antigua la que mejores valores obtuvo. El impacto de las ECAs fue rápido y persistente en los indicadores relacionados con la participación, el acceso a servicios básicos y la conservación de los recursos naturales. El estudio demostró un claro potencial de las ECAs en la mejora general de la sostenibilidad y la seguridad alimentaria de estos sistemas, sin embargo se observó una relación directa entre el aumento de producción agrícola y el uso de insumos externos, lo que puede suponer un punto crítico para los ideales sostenibles. ABSTRACT During the last decades, sustainable agriculture has been the subject of considerable academic interest and debate, not only in conceptual terms, but also in methodological ones. The persistence of high levels of environmental degradation and food insecurity in many regions has led to new initiatives focused on revitalizing peasant agriculture and renewed discussions of the role of sustainable agriculture as an engine for development, environmental conservation and poverty alleviation. Therefore, to assess mountain farming systems, we must consider food dimension and taking into account the specificities of the mountain systems as the foundation of sustainability. When evaluating contribution of technological and management alternative proposals in achieving sustainability and food security for peasant farming systems in Mesoamerican highlands, three research questions arise: • Is sustainability of peasant-farming systems being evaluated taking into account climate variability, participation of farmers and temporal dynamics? • Can we rescue common trends in these systems and extrapolate the results to other areas? • What alternative proposals that have been conducted are unequivocally positives? In this document, we present three evaluations of sustainability that try to highlight the challenges and opportunities that currently face mountain farming systems in Mesoamerica. First, we evaluate the sustainability of three agricultural management systems in two contrasting weather years. We determined that during the first year that exposed heavy rains and moderate temperatures, low-input systems, which are based on the use of organic fertilizers and crop rotation, provided better results in terms of ecological indicators and equal results in terms of economic and social indicators than those achieved using a high chemical input system. In the second year, which featured early frosts and a winter drought, productivity declined in all systems; however, the most diversified systems (in terms of the maize varieties grown and the sowing of other crops) more successfully resisted these climatic adversities. Second, we evaluate the farmers’ perception to determine the key drivers for achieving their sustainability and food and nutritional security. We determined that the key factors identified by farmers (landholding size and slope of cropland) exerted significant impacts on economic disparities but did not explain the malnutrition levels. We compared two contrasting hamlets according to their energy and protein supply, one namely Limón Timoté (LT), which did not present food problems and Limón Peña Blanca (LP), which did exhibit food insecurity. The results showed that FNS is linked to sustainability, and it is primarily related to the sustainability attributes of self-reliance and equity. Although the more marginated and inaccessible community exhibited more food insecurity, food and nutritional security depend upon a complex array of self-sufficiency strategies that remain linked to individual household idiosyncrasies. Third, we evaluated the impact of farmer field schools for improving the sustainability and food security of peasant mountain systems. In order to appreciate the long-term impact, we studied three communities where FFSs were implemented eight, five and three years ago, respectively. We found that FFSs have a gradual impact, as the community that first implemented FFSs scores highest. The impact of FFSs was broad and long-lasting for indicators related to participation, access to basic services and conservation of natural resources. This study demonstrates the potential of FFSs, but more attention will have to be paid to critical indicators in order to scale up their potential in the future. We observed a direct relationship between the increase in agricultural production and the use of external inputs, which is a critical point for sustainable ideals.

State (un)Sustainability in the Southern Mediterranean and Scenarios to 2030: The EU’s Response. MEDPRO Policy Paper No. 1/August 2011(updated April 2012)

This research project is the product of a conviction, corroborated by the events that have overwhelmed the Arab world since December 2010, that sustainability is essential to any understanding of Mediterranean politics. Sustainability has too often been confused with stability in policy debates in the region and in the West. Not only are these two concepts distinct, with sustainability being broader and deeper than stability, but stability, as interpreted with regard to the regimes in the region, has often run counter to the very conditions that underpin state sustainability. Believing and thus pursuing regime stability has ultimately acted to the detriment of a more organic understanding of state sustainability.
