La pollution des produits agroalimentaires et des eaux environnementales par les substances phytosanitaires et les médicaments est une réelle préoccupation de santé publique. Il existe aujourd’hui de nombreuses méthodes d’analyses quantitatives développées sur des appareils de type triple quadripôle pour leur détection mais elles ne se préoccupent peu ou pas des résidus médicamenteux et des produits de dégradation abiotique ou biologique des polluants et sont limitées à un nombre restreint et figé de molécules.Dans ce contexte, nous avons développé une méthode d’analyse basée sur la métabolomique par chromatographie liquide haute performance couplée à la spectrométrie de masse à ultra-haute résolution (LC-HRMS). Deux matrices (miel et eau souterraine) ont ainsi été étudiées comme preuve de concept. Nous avons montré que la LC-HRMS associée à des outils de fouille de données permet (i) une recherche ciblée de polluants prioritaires, (ii) la détection sans a priori de contaminants inattendus ou inconnus et (iii) la recherche de métabolites nécessaire à la classification des échantillons en fonction de leur métadonnée (adultération, origine géographique, etc.). Ensuite, une approche semi-quantitative ciblée large spectre a été développée et validée pour la détection de pesticides, médicaments et métabolites dans l’eau par couplage de la SPE en ligne avec l’UHPLC-ESI-HRMS. Cette méthode permet la détection de 539 contaminants organiques en 36 minutes dans 5 millilitres d’eau au seuil minimum réglementaire de 0,1 µg/L. L’étude de 26 eaux du robinet de la région parisienne a permis de mettre en évidence la présence à l’état de trace de 37 polluants dont 6 médicaments. / Pollution of agrifood and environmental water by pesticides and drugs is a real public health concern. There are many quantitative methods developed on triple quadrupole mass spectrometer for their detection, but drug residues and abiotic or biological degradation of pollutants are generally not considered and are limited to a predetermined and restricted list of molecules.In this context, we have developed an analytical method based on metabolomic analyses by high performance liquid chromatography coupled with ultra-high resolution mass spectrometry (LC-HRMS). Two matrices (honey and groundwater) were investigated as proof of concept studies. We showed that LC-HRMS associated to data mining tools enables (i) targeted analyses of pollutants, (ii) detection of untargeted and unknown xenobiotics, and (iii) detection of metabolites useful for the characterization of matrices. Then, a large targeted and semi-quantitative approach has been developed and validated for the detection of pesticides, drugs and metabolites in water samples by using on line SPE and UHPLC-ESI-HRMS. This method allowed the detection of 539 organic contaminants at the MLR of 0.1 µg/L in 36 minutes with only 5 milliliter of water. A study of 26 tap water samples from the Paris region showed the presence of 37 pollutants including 6 drugs.

Innovation is essential to promote human progress and to improve the humans' quality of life, but it should be done in a social and environmental context and in accordance with the principles of sustainable development. To achieve this challenge the environmental innovation guidelines should be taken into account. In this line, it is necessary to analyze the life cycle assessment (LCA) of any product, process or service and compute its environmental impacts. Despite the rapid evolution of environmental methods and tools and the increase of sustainability studies in recent years, LCA remains an area that still has to face major development challenges. This thesis provides an analysis from a new perspective with the intention to serve as a support in the conceptual and empirical application of the LCA in the Agri-food sector. It consists of a qualitative analysis designed to know the type of relationship between the different actors involved and their information exchange needs. The case study made it possible to compare the differences between the academic and the industrial fields, as well as the differences between Spanish and Brazilian LCA experts. Through expert panels, 40 specialists were interviewed and were asked to made a survey to evaluate experts' relationships using the Social Network Analysis method (SNA). Moreover, the network flow of environmental information in Brazil and Spain was mapped. A second quantitative study was carried out reviewing 70 scientific publications of LCA in the Agri-food sector according to a checklist based on the definition of 20 control variables. The objective was to evaluate the quantity and quality of the information enclosed in the different works. To do this, the entropy and diversity of information were calculated using the Shannon and the equitability indexes, using the number of inputs considered in each impact category. A threshold of minimum information is proposed, using percentiles 25 and 75 (Tukey values) of the calculated Shannon indexes from the papers sample. Moreover, a cluster analysis was done using 10 out the 20 control variable to classify LCAs into clusters with similar levels of performance for the LCAs of the same group and different from the LCA belonging to the other groups. Based on the analysis of the centers of resulting group, the strengths and weaknesses of each group were identified. Then, a roadmap or improvement plan was succinctly defined, pointing out the actions to be taken to improve the performance levels in each group in the short, medium and long term. Finally, a set of actions to improve and facilitate the implementation of LCA in the Agri-food sector was defined as a kind of good practice manual. In sum, it could be concluded that this present thesis could serve to improve the LCA studies performance levels for industry, and, at the same time, it could serve as a baseline with which to compare academic standards of a more academic works. / La innovación es esencial para promover el progreso de la humanidad y la mejora de la calidad de vida, pero debe realizarse respetando un suelo social y un techo ambiental de acuerdo con los principios del desarrollo sostenible. Para intentar conseguirlo surge la innovación ambiental. En esa línea, resulta necesario analizar el ciclo de vida (ACV) de cualquier producto, proceso o servicio y computar sus impactos ambientales. A pesar de la rápida evolución de los métodos y herramientas y del incremento de estudios en los últimos años, el ACV sigue siendo un área que se enfrenta a retos de desarrollo importantes. Esta tesis proporciona un análisis desde una perspectiva nueva con la intención de servir de apoyo en la aplicación conceptual y empírica del ACV en el sector agroalimentario. Consta de un análisis cualitativo destinado a conocer el tipo de relación entre los distintos actores involucrados y sus necesidades de intercambio de información. El caso de aplicación permite comparar las diferencias entre el mundo académico y el industrial, así como las diferencias entre expertos en ACV de España y Brasil. A través de paneles de expertos se entrevistó a 40 especialistas y con un cuestionario se evaluó la red de contactos usando el método de Análisis de Redes Sociales (SNA). Con todo se mapeó el flujo de información ambiental en Brasil y España. En un segundo estudio cuantitativo se realizó una revisión crítica de 70 publicaciones científicas de ACV pertenecientes al sector agroalimentario, evaluando las mejores revistas y congresos de todo el mundo entre 2010 y 2016 a partir de la definición de 20 variables de control. El objetivo era evaluar la cantidad y calidad de la información contenida en los distintos trabajos. Para ello se calculó la entropía y diversidad de la información a través del Índice de Shannon y del cálculo de la heterogeneidad en lo refiere al número de inputs considerados en cada categoría de impacto. Tras los valores obtenidos se proponen unos umbrales de información mínima aconsejable usando como límites el valor de las bisagras de Tukey de la distribución de los 70 índices de Shannon calculados. Por otra parte, a partir de 10 de las 20 variables de control se agruparon los distintos ACV analizados con objeto de clasificarlos en grupos con parecido nivel de desempeño para los ACV de un mismo grupo y distinto al de los ACV pertenecientes al resto de grupos. A partir del análisis del análisis de los centros de cada grupo, se identificó las fortalezas y debilidades de cada grupo, para más tarde definir de forma sucinta un mapa de ruta o plan de mejora apuntando las acciones a realizar para mejorar los niveles de desempeño en el corto, medio y largo plazo de cada grupo. Finalmente, se definió a modo de un manual de buenas prácticas un conjunto de acciones a realizar para mejorar y facilitar la realización de ACV en el sector agroalimentario. Con todo. Se podría concluir que la tesis puede servir para mejorar los niveles de desempeño de la realización futura de estudios de ACV en el sector industrial, al tiempo que podría servir como línea de base con la que comparar los estándares de estudios de carácter más académico. / La innovació és essencial per a promoure el progrés de la humanitat i la millora de la qualitat de vida, però ha de realitzar-se respectant un sòl social i un sostre ambiental d'acord amb els principis del desenrotllament sostenible. Per a intentar aconseguir-ho sorgix la innovació ambiental. En eixa línia, resulta necessari analitzar el cicle de vida (ACV) de qualsevol producte, procés o servici i computar els seus impactes ambientals. A pesar de la ràpida evolució dels mètodes i ferramentes i de l'increment d'estudis en els últims anys, l'ACV continua sent una àrea que s'enfronta a reptes de desenrotllament importants. Esta tesi proporciona una anàlisi des d'una perspectiva nova amb la intenció de servir de suport en l'aplicació conceptual i empírica de l'ACV en el sector agroalimentari. Consta d'una anàlisi qualitativa destinada a conèixer el tipus de relació entre els distints actors involucrats i les seues necessitats d'intercanvi d'informació. El cas d'aplicació permet comparar les diferències entre el món acadèmic i l'industrial, així com les diferències entre experts en ACV d'Espanya i Brasil. A través de panells d'experts es va entrevistar a 40 especialistes i amb un qüestionari es va avaluar la xarxa de contactes usant el mètode d'Anàlisi de Xarxes Socials (SNA). Amb tot es dissenyà el flux d'informació ambiental a Brasil i Espanya. En un segon estudi quantitatiu es va realitzar una revisió crítica de 70 publicacions científiques d'ACV pertanyents al sector agroalimentari, avaluant les millors revistes i congressos de tot el món entre 2010 i 2016 a partir de la definició de 20 variables de control. L'objectiu era avaluar la quantitat i qualitat de la informació continguda en els distints treballs. Per a això es va calcular l'entropia i diversitat de la informació a través de l'Índex de Shannon i del càlcul de l'heterogeneïtat en el que es refereix al nombre d'inputs considerats en cada categoria d'impacte. Després dels valors obtinguts es proposen uns llindars d'informació mínima aconsellable usant com a límits el valor de les frontisses de Tukey de la distribució dels 70 índexs de Shannon calculats. D'altra banda, a partir de 10 de les 20 variables de control es van agrupar els distints ACV analitzats a fi de classificar-los en grups amb paregut nivell d'excel·lència per als ACV d'un mateix grup i diferent del dels ACV pertanyents a la resta de grups. A partir de l'anàlisi de l'anàlisi dels centres de cada grup, es va identificar les fortaleses i debilitats de cada grup, per a més tard definir de forma succinta un mapa de ruta o pla de millora apuntant les accions a realitzar per a millorar els nivells d'exercici en el curt, mitjà i llarg termini de cada grup. Finalment, es va definir a manera d'un manual de bones pràctiques un conjunt d'accions a realitzar per a millorar i facilitar la realització d'ACV en el sector agroalimentari. Amb tot, es podria concloure que la tesi pot servir per a millorar els nivells d'exercici de la realització futura d'estudis d'ACV en el sector industrial, alhora que podria servir com a línia de base amb què comparar els estàndards d'estudis de caràcter més acadèmic. / Oliveira Barros, FM.

Yes / The Sustainable Development Goals (SDGs) present the emerging need to explore new ways of AgriFood production and food security as ultimate targets for feeding future generations. The study adopts a Design Science methodology and proposes Artificial Intelligence (AI) techniques as a solution to food security problems. Specifically, the proposed artefact presents the collective use of Agricultural Technology (AgriTech) drones inspired by the biomimetic ways of bird swarms. The design (artefact) appears here as a solution for supporting farming operations in inaccessible land, so as unmanned aerial devices contribute and improve the productivity of farming areas with limited capacity. The proposed design is developed through a scenario of drone swarms applying AI techniques to address food security issues. The study concludes by presenting a research agenda and the sectoral challenges triggered by the applications of AI in Agriculture. / European Union's H2020 research and innovation programme under the Marie Skłodowska-Curie grant (agreement No. 746667)

Seu principal objetivo é estudar cadeias produtivas curtas e encurtadas em sistemas agroalimentares. A filiera corta trabalha no sentido de reduzir o número de intermediários comerciais, colocando em contato mais direto produtores e consumidores, criando valor agregado no território de origem e reforçando as especificidades do produto. As cadeias curtas têm como objetivo saltar intermediações, permitindo à empresa agrícola aumentar sua margem de lucro, oferecendo produtos de melhor qualidade a preços menores para o consumidor final, favorecendo a relação entre quem produz e quem consome. O modelo econômico é o de mercados agrícolas de venda direta. As cadeias produtivas curtas têm como força a relação direta entre consumidor e produtor. Alguns fatores presentes na decisão de compra de consumidores de produtos de cadeias curtas são: a qualidade dos produtos; a ligação com o território (tipicidade, certificados etc.); método de produção da agricultura biológica; e proximidade do mercado consumidor. Em particular, a posição favorável da empresa, nas adjacências de centros urbanos e de sítios de interesse turístico, histórico, arqueológico ou natural. O objetivo principal de pesquisa foi descrever como pode ser organizada uma cadeia produtiva agroalimentar cujo objetivo seja aproximar produtor e consumidor eliminando etapas e operações intermediárias. O método de pesquisa foi o estudo de caso múltiplo. A pesquisa foi feita em duas etapas, uma na Itália e outra no Rio Grande do Sul. Foram entrevistados cinco agentes italianos (dois pesquisadores, dois empreendedores e um representante de classe) e três empreendedores gaúchos. Foi obtida uma lista de aspectos presentes nas operações encurtadas italianas e comparados com os gaúchos. Ao fim, foram feitas considerações caso se deseje ampliar a abordagem no RS. / This master level thesis has addressed a movement that has been consolidated in Europe and has been discussed and disseminated, primarily in Italy: the short supply chain approach. Its main objective is to study short and shortened supply chains in agrifood systems. Short supply chains ought to reduce the number of commercial intermediaries, putting in more direct contact producers and consumers, creating added value in the territory of origin of goods and reinforcing the specificity of products. The short chains are aimed at jump intermediation, allowing to increase farm profit margins by offering better quality products at lower prices to final consumers and fostering the relationship between those who produce and those who consume agrifood products. The economic model of agricultural markets is the direct sale. Short supply chains have strength as the direct relationship between consumer and producer. Some of these factors in purchasing decisions of consumers of products of short chains are: product quality, the link with the territory (typicality, certificates etc.), method of production based on organic farming, and proximity to the consumer market. In particular, it worths the favorable position of the company, in the vicinity of urban centers and tourist sites, historical, archaeological or natural. The main research objective was to describe how can be organized agrifood production chain whose aim is to bring producers and consumers by eliminating intermediate steps and operations. The research method was the multiple case study. The survey was conducted in two stages, one in Italy and another in Rio Grande do Sul. Five Italian agents (two researchers, two entrepreneurs and a class representative) and three entrepreneurs from Rio Grande do Sul were interviewed. We obtained a list of issues involved in shortened operations in Italy and compared with those in Rio Grande do Sul. In the end, there are considerations about how to expand the approach in RS, based on research findings.

Under this perspective, the general objective of this thesis is to comprehend how agroecology entered the governmental agenda and the formulation process of the National Policy on Agroecology and Organic Production (PNAPO) and the National Plan for Agroecology and Organic Production (PLANAPO). The specific objectives are: comprehend the influence of the institutional and political context in the building of the agenda; identify the historical background and agroecology founding aspects at the brazilian public policies after 1985; identify the main governmental decision-makers, actors and civil society groups who acted on the construction of PNAPO and PLANAPO; understand how the junction of the problems flows and alternatives was made to originate the Policy.The theoretical framework employed comprises the Gramscian concept of Estate, analysis of the neo-institutionalist public policies and of the public policy cycle, taking into consideration the referential of agrifood system, food issues and rural development. Two theoretical models were used as analytical references on the policy process, specifically for the governmental agenda definition (agenda setting) and the formulation phase: the Multiple Stream Model from Kingdom, and the Punctuated Equilibrium Model from Frank Baumgartner and Brian Jones. The results of the desk research of relevant literature, secondary sources and semi-structured interviews revealed that the agroecological approach gained space in some public policies since 2003. The convergent actions from the agroecological and organic movements, especially peasant and rural women organizations, together with the favorable political moment, were fundamental factors for the entrance at the governmental agenda and the formulation of PNAPO and PLANAPO. The transformation process of the governmental agenda into public policy occurred by means of open and transparent dialogue between civil society representatives and the federal government, in a political and historical context of a government that created dialogue mechanisms with society and opened up for agendas that were not accepted before. Apart from the limitations, conflicts and constraints, PNAPO and PLANAPO have the great merit of being the affirmation of an agenda that counteracts the agribusiness. They constitute a mark and a political achievement and put the agroecological agenda in another level at the public policies. However, the agroecological approach is not yet consolidated as a federal government strategic and central policy that sustains the transformations of the agrifood system and of the rural development aiming food sovereignty and the Human Right to Adequate Food. / A agroecologia constitui-se em um enfoque contempor?neo inserido na constru??o de pol?ticas p?blicas interrelacionado ao desenvolvimento rural, soberania alimentar e Direito Humano ? Alimenta??o Adequada (DHAA), no contexto do sistema agroalimentar e da conjuntura pol?tica brasileira a partir de 2003. Nessa perspectiva, o objetivo geral desta Tese consiste em compreender como ocorreu a entrada da agroecologia na agenda governamental e o processo de formula??o da Pol?tica Nacional de Agroecologia e Produ??o Org?nica (PNAPO) e do Plano Nacional de Agroecologia e Produ??o Org?nica (PLANAPO). Os objetivos espec?ficos s?o: compreender a influ?ncia do contexto pol?tico e institucional para a forma??o da agenda; identificar os antecedentes hist?ricos e os aspectos fundantes da agroecologia nas pol?ticas p?blicas brasileiras ap?s 1985; identificar os principais decisores governamentais, atores e grupos da sociedade civil atuantes na constru??o da PNAPO e do PLANAPO; compreender como foi feita a jun??o dos fluxos de problemas e alternativas que deram origem ? Pol?tica. O marco te?rico utilizado engloba o conceito gramsciano de Estado, an?lise de pol?ticas p?blicas neoinstitucionalista e do ciclo da pol?tica p?blica, acrescidos do referencial de sistema agroalimentar, quest?o alimentar e desenvolvimento rural. Utiliza-se como refer?ncia anal?tica sobre processo de pol?ticas p?blicas (policy process), especificamente para a defini??o de agenda governamental (agenda-setting) e a etapa de formula??o, dois modelos te?ricos: o Modelo de Correntes M?ltiplas (Multiple Stream Model) de Kingdon e do Equil?brio Pontuado (Ponctuated Equilibrium Model) de Frank Baumgartner e Brian Jones. Os resultados da pesquisa documental, fontes secund?rias e entrevistas semiestruturadas evidenciaram que o enfoque agroecol?gico ganha espa?o em algumas pol?ticas p?blicas a partir de 2003. A atua??o convergente do movimento agroecol?gico e org?nico, com destaque para as organiza??es das mulheres trabalhadoras rurais e camponesas, aliada a um momento pol?tico favor?vel, foi fator fundamental para a entrada na agenda governamental e a formula??o da PNAPO e do PLANAPO. O processo de transforma??o da agenda governamental em pol?tica p?blica aconteceu por meio de um di?logo aberto e transparente entre os representantes da sociedade civil e do governo federal em um contexto pol?tico-hist?rico de um governo que criou mecanismos de di?logo com a sociedade e que se abriu para pautas antes n?o acolhidas. Apesar das limita??es, conflitos e lacunas, a PNAPO e o PLANAPO t?m o grande m?rito de serem a afirma??o de uma agenda que se contrap?e ao agroneg?cio. Constitui-se em marco e conquista pol?tica e colocou a agenda da agroecologia nas pol?ticas p?blicas em outro patamar. Entretanto, o enfoque agroecol?gico ainda n?o se consolidou como uma pol?tica estrat?gica e central do governo federal que sustente as transforma??es do sistema agroalimentar e do desenvolvimento, com vista ? garantia do DHAA e da soberania alimentar.

Nanotechnology, the scientific study of manipulating matter on an atomic scale (1 to 100 nanometers) that provides new properties in materials and devices had received considerable research attention and public funding support during the last decade in the US. This emerging technology promises to improve the competitiveness of most of the US industrial sectors. Malerba (2004) an innovation system researcher has developed the theoretical framework "Sectoral System of Innovation (SSI)" to study the process by which new technologies and knowledge are produced and transferred to industrial sectors, where actors interact based on an institutional framework to generate innovation processes. In this dissertation I studied the agriculture and food processing sector, which is a key sector of the US economy that has provided with enough food for the US population, but in an unsustainable way that has harmed the environment, natural resources and human health. The US agrifood sector is facing new challenges of increasing food demand, which need to be addressed in a more sustainable way that takes consideration on economic, environment, and social aspects. The main questions that this dissertation research focuses on studying how much attention the public nanotechnology agrifood research agenda has paid to sustainability issues during the last decade in the US and what role has played the system's actors in influencing this research agenda. The analysis of the policy process in which system's actors try to influence the research agenda is framed in the Advocacy Coalition Framework (Sabatier 1993) that complemented the Sectoral System of Innovation approach in studying the formation of advocacy groups to achieve their coalition's policy goals. Three data sources were utilized to achieve my research goals, the CNS-ASU nanotechnology publications dataset 2000-2010(Porter A, Youtie J et al. 2007; De Bellis 2009)which was used to conduct a bibliometric analysis of the agrifood nanotechnology research publications in the US, semi-structured interviews with key actors and their interaction in advocacy coalition groups, and a literature review of several official documents and public hearing with respect to the US nanotechnology system to evaluate the influence of advocacy groups in the policy process. Utilizing Vantage point data mining and Nvivo qualitative analysis software I conducted the data analysis of my research. The results show increasing research attention toward environmental research and food safety issues that can indirectly impact positively on sustainability development, as well as increasing research attention in studying environmental, health and safety issues (EHS) that can reduce potential risks. The analysis of actors' interaction to influence the policy process, two advocacy coalitions was identified. On one side, a coalition that advocate for more research funding oriented to applied research to achieve the potential that this coalition members believe this technology has to revolutionize the way food is produced giving more competitiveness to the US agrifood sector, this coalition is composed by researchers, federal agency managers and industry representatives. On the other side, a rival coalition that raise concerns respect to potential risks associated to this technology that required to be addressed by the public research agenda. This coalition mainly composed by environmental non-governmental organizations (NGOs) and other social actors claim for a regulatory framework that guarantee a nanotechnology development environmental friendly that benefit the society. The influence of these two coalitions have succeed in allocating more federal funding resources to research nanotechnology in the agrifood sector, with particular emphasis in EHS research that show the right path to a sustainable development that guarantee enough resources for the future generations.

This study aims to evaluate conceptual considerations of the sociology of agriculture and food from inside and outside of the literature in relation to transnationalization and its claim on the emergence of a transnational state. Although the history of the literature can be traced back to mid-1970s, its development corresponds to 1990s which is also the period that witnessed the hegemony of the concept of globalization in social sciences. This study argues that the claim on transnationalization reflects the intimate relationship of sociology of agriculture and food with the globalist interpretation of the concept of globalization or globalization theory which suffers from methodological and theoretical problems mainly in relation to the analysis of immanent contradictions and distinctive features of capitalism. With the criticism of the concepts of globalization and transnationalization, this study aims to break the intimate relationship of the sociology of agriculture and food with the globalization theory and suggests that the concept of imperialism is a powerful analytical concept in comprehending the transformation of capitalist relations, particularly the agrifood relations since late 1970s. In other words, this study aims to reevaluate the concepts (agrifood system and food regime) and problematics formulated in the sociology of agriculture and food literature within the theoretical framework based on the concept of capitalist imperialism exemplified in the analysis of transformation of agrifood relations since 1980 in the case of Turkey.

In just over a decade, soybean production in Uruguay emerged from almost non-existence to second most important export product. The extraordinary rapid soybean expansion is often referred to as representing changes that go far beyond the mere substitution of one agrarian activity for another, but evolved into a broad societal concern. Accordingly, the soybean expansion has not only been debated in national media, but among NGO’s, firms, scholars, farmers, political parties as well as within broad sectors of the state apparatus. Although the views expressed are allegedly about the soybean expansion, they are found to reflect much deeper values and assumptions about what is good, appropriate and desirable. All this ultimately represents discordant alternative visions and paths of development. This dissertation outlines and analyzes the dynamics of different, complementary and competing views on the soybean expansion in Uruguay between 2002 and 2013. These have in turn been related to wider debates about “development” of longer historical roots within the social sciences. Rather than exclusively relying on the mediatized accounts expressed in the public debate, often posed in a rather superficial and antagonistic way in accordance to some media logic, this study has made intensive use of in-depth interviews. This has allowed for deeper, more complex and nuanced accounts, as well as made possible to include voices that were only indirectly “represented” in the public debate. The main agreements and disagreements expressed in relation to the soybean expansion have been outlined, described, situated and explored. While constant contingency and unfixity are acknowledged, three main broader competing world-views, or discourses, have also been identified. These are discerned through the analysis of patterns of regularities in the articulations about the soybean expansion. The first is labelled “agro-ecology discourse”, reflecting anti-capitalist notions and centered in values of local autonomy and justice. The other is labelled “pro-market discourse”, reflecting market faith and centered in values of growth, dynamism and meritocracy. The third is labelled “pro-public regulation discourse”, reflecting beliefs in development intervention and centered in values of progress and upgrading. / FORMAS - 2006-2246 "The soybean chain in contemporary agro-food globalization: challenges for a sustainable agro-food system"

L'objectif principal de ce travail était de répondre à la question suivante : la montée de l'insécurité alimentaire a-t-elle un impact sur les Systèmes Agroalimentaires Localisés (Syal) ? Et, plus particulièrement, les Syal sauront-ils substituer à la logique de « produire peu et mieux » celle de « produire assez et mieux » sans perdre leur identité et reproduire le modèle agricole productiviste ? Deux analyses ont été menées pour y répondre. La première a porté sur les principaux facteurs de l'insécurité alimentaire ainsi que sur les bases conceptuelles et théoriques des Syal resitués dans cette problématique. La seconde a été consacrée à l'évolution de ce dernier face à la nécessité d'accroître les disponibilités alimentaires, et ce à travers l'étude du Système Oléicole dans l'Espace de Saïs-Meknès au Maroc (SOM). Les analyses ont révélé qu'il existe des « solutions médianes » qui conjuguent « produire assez » et « produire mieux » : il s'agit d'une agriculture écologiquement intensive, appuyée par l'entretien et la modernisation des unités traditionnelles – les maâsras - et semi-modernes de trituration. De telles solutions permettraient d'améliorer les disponibilités alimentaires et d'offrir en même temps des produits de qualité, tout en restant lié au territoire et aux valeurs sociétales, notamment en matière environnementale / This study aims at answering the following question: does the rise of food security issues have an impact on Localized Agrifood Systems (Syals)? More precisely, will the Syals succeed in replacing the logic of "producing little but better" by "producing enough and better" without losing their identity in productivist agricultural models? Two analyses have been conducted to find an answer to these questions. The first one focused on the determinants of food security and on the theoretical foundations of Syals as potential response to this challenge. The second one is devoted to the evolution of Syals given the needs for increases of food supply, more particularly in the case of the Olive System in the Saïs-Meknes Area in Morocco (SOM). These analyses led to the identification of "median solutions" which combine the logics of "producing enough" and of "producing better": ecologically intensive agriculture connected with the maintenance and the modernization of the traditional maâsras and the semi-modern crushing units. Such solutions would enable to improve food supply and, in the same time, to provide quality products while remaining linked to a territory and to the societal values including environmental dimension
