Texto completoThis thesis addressed three issues related to innovation and agrifood trade through three essays. The rst essay deals with the implications of agrifood trade liberalization on export prices and quality upgrading, theoretically and empirically. Based on the recent literature on international trade, the theoretical investigation extends an existing model by incorporating the reduction of output tari s as an indicator of trade liberalization likely to a ect export quality. The theoretical model informs that the e ects of trade liberalization on the quality of exported products depend strongly on the level of product di erentiation. Indeed, trade liberalization leads to more quality improvement for di erentiated products than for homogeneous products. These theoretical conclusions have been tested with data from OECD member countries. Empirical results largely corroborate theoretical conclusions. The second essay is devoted to the analysis of the direct and indirect e ects (via innovation) of nancial constraints on the export performance of agrifood rms in African countries. The literature argues that nancial constraints negatively impact rms' innovation activities. In addition, innovation is one of the main determinants of export performance. It is therefore relevant to consider nancial constraints to directly impact the export performance of agrifood rms through increased costs related to export activities, but also indirectly through the reduction of rm incentives to innovate. Our theoretical model suggests that the impact of innovation on export performance depends on two e ects: the cost e ect and the demand-creation e ect. Innovation induces improved export performance only if the demand-creation e ect is greater than the cost e ect. Moreover, the most nancially constrained rms are less inclined to innovate and are less successful in foreign markets. These theoretical conclusions were tested on data about agrifood rms from 10 African countries. In general, empirical evidence con rms the theoretical conclusions that nancial constraints are damaging to the performance of rms' exports. v The last essay of this thesis questions the implications of R&D investment in the agricultural sector on export duration of agricultural products in ECOWAS member countries. There is little research on export survival in the agricultural sector. More precisely, those addressing the issue of the possible e ects of public R&D investment on the duration of exports are almost non-existent. Given the importance and role of the agricultural sector in the economies of ECOWAS member countries and the low level of investment in the agricultural sector, this essay contributes to lling this gap. Two measures of R&D investments were used as explanatory variables for the probability of export survival: the annual average share of R&D investments in agricultural GDP in the last ve years before the start of the trade episode (upstream investment) and the average annual share of R&D investments in agricultural GDP realized during the trade episode (downstream investment). The empirical results indicate that, in general, R&D investments increase the agricultural export survival rate of ECOWAS countries. In addition, this e ect is not linear as the increase in R&D expenditures tends to reduce the probability of export survival above a certain threshold. The results also indicate heterogeneity across countries and the number of past trade episodes.

Texto completoL’attività di ricerca, i cui risultati sono oggetto della dissertazione di dottorato, ha riguardato lo studio delle potenzialità applicative del DNA barcoding, una tecnica molecolare volta all’identificazione degli organismi sulla base dei polimorfismi di specifiche sequenze nucleotidiche localizzate nei genomi plastidiale, mitocondriale e cloroplastico. Il progetto di ricerca ha previsto l’impiego di questo approccio per il riconoscimento di specie ai fini della tracciabilità genetico-molecolare di prodotti agro-alimentari, sia di origine animale (pesci, molluschi e crostacei) che vegetale (fagiolo e vite). Inizialmente si è proceduto all’individuazione degli organismi su cui condurre l’analisi: si sono collezionate linee pure di fagiolo (Phaseolus vulgaris L.), cloni di vite (Vitis vinifera L.) e campioni di pesci, crostacei e molluschi acquistati presso famose GDO o ai mercati locali di Chioggia e Sottomarina. In particolare, per quanto concerne la scelta delle specie ittiche su cui condurre l’analisi, si è svolta un’estesa indagine di mercato con l’intento di individuare le specie maggiormente coinvolte in falsificazioni alimentari, cioè sostituzione di specie pregiate con altre di valore inferiore. Si è successivamente proceduto alla purificazione di 37 campioni di DNA genomico e alla loro caratterizzazione dal punto di vista molecolare mediante amplificazione e sequenziamento di specifici geni mitocondriali, quali cox1 (Cytochrome oxydase subunit I), 16S-rDNA (16S small ribosomal subunit RNA) e cob (cytochrome b). Una volta acquisiti questi dati, l’interrogazione di due banche dati disponibili on line, BOLD per il gene cox1 e GenBank per tutti e tre i geni, ha consentito di identificare l’origine dei campioni confermando nella maggioranza dei casi quanto dichiarato nell’etichetta di accompagnamento del prodotto alimentare. In cinque situazioni non è stato possibile stabilire con certezza l’origine del campione e questo potrebbe indicare possibili casi di sostituzione, fraudolenta o accidentale. Il DNA barcoding pertanto è risultato utile ai fini dell’identificazione di specie in tutti e tre i taxa studiati, pesci, molluschi e crostacei, e il gene cox1 si è dimostrato un ottimo target per questi scopi eccetto che in tre casi particolari, i generi Thunnus, Macruronus e Gadus. Inoltre è risultato evidente che nonostante GenBank persista come la banca dati più ricca in termini di numero di sequenze depositate, il BOLD sta rapidamente incrementando la quantità di informazioni contenute al suo interno lasciando presupporre che in breve tempo diventerà la banca dati di riferimento per studi di genetica forense e di tracciabilità genetica. Per quanto riguarda le specie vegetali, l’obiettivo era l’identificazione univoca di specie, e soprattutto delle loro varietà quando fondate su un solo genotipo (linee pure, ibridi e cloni). Nel caso di fagiolo, si sono isolati i DNA genomici da 54 varietà di Phaseolus vulgaris, 18 provenienti dal Centro America, 12 dal Sud America e 24 line pure coltivate e commercializzate in Italia, insieme con alti 6 campioni usati come fuori gruppo (Phaseolus coccineus, Phaseolus lunatus e Vigna unguiculata). Sono risultate indispensabili indagini preliminari di polimorfismi di singoli geni al fine di determinare la variabilità genetica tra le varietà e la tracciabilità genetica di singole varietà. La caratterizzazione, tramite l’amplificazione di 7 differenti regioni cloroplastiche e due nucleari seguita da un approccio fenetico, ha confermato le potenzialità della tecnica come strumento efficace per la distinzione delle specie, mentre è risultata scarsamente informativa per il riconoscimento di singole varietà. Da qui si è rivelata necessaria l’adozione di un approccio alternativo, basato sulla determinazione della composizione nucleotidica e del polimorfismo a carico di ciascun gene esaminato, che ha permesso di definire 16 aplotipi corrispondenti ad altrettanti sottogruppi varietali, ciascuno costituito da accessioni Mesoamericane o Andine insieme con le varietà Italiane. Infine l’applicazione del DNA barcoding per la distinzione di cultivar di vite ha richiesto l’abbandono dello studio del genoma cloroplastico, troppo poco variabile, a favore di quello nucleare. Si sono isolati i DNA genomici da 123 cultivar di Vitis vinifera e da altre 5 specie (V. rupestris, V. riparia, V. labrusca, V. cinerea e V. berlandieri) e si sono amplificati 4 EST ed il gene GAI1 (gibberellins insensitive-like). L’analisi bioinformatica è ancora in corso, ma risultati preliminari fanno ipotizzare l’esistenza di aplotipi cultivar-specifici che potrebbero venir impiegati in futuro per risolvere i frequenti casi di sinonimie ed omonimie diffusi all’interno di questa specie. Infine un’altra interessante applicazione da un punto di vista economico potrebbe essere l’impiego di questi aplotipi cultivar-specifici per la tracciabilità genetica dei vini e la tutela delle denominazioni controllate da casi di falsificazione e concorrenza sleale.

Texto completoInnovation is recognized as the process of renovation of the company, ensuring its survival and success. Although, to combine and recombine all these aspects is not an easy task. In an ideal and utopic world, a firm would be composed by workers with equal and complete knowledge about all the operations, methods, processes and techniques enrolled in the firm’s activities. To the intra-firm perspective, Paruchuri (2010) argues that a firm that can improve the diffusion of knowledge internally will enhance its innovative activity. Aalbers (2015), reflecting on the governance of knowledge sharing inside organizations, suggests that knowledge may be difficult to transfer because of the boundaries dynamics. Due to this dynamic, innovation centered, it is important to create new ways of analyzing and developing the firm’s activities, aiming to enhance its performance and to better understand solution enablers for the new challenges to come. Therefore, the research question emerges: How can firms manage intra-firm interactions to enhance the innovative activities? To answer this question, we designed and performed a qualitative study with 8 HIFs (Highly Innovative Firms), 4 located in Brazil and 4 located in France. We used the dimensions of interactions and brokerage roles adapted from Aalbers (2015), Tsang (2015) and Indarti (2010) to develop a semi-structured instrument for the interviews. We analyzed the interactions during a project of product development in each firm, and the interactions were classified according to: Hierarchy (Horizontal or Vertical); Reach (Unit or Cross-unit); Type (Formal or Informal) and we used Intensity (Frequency) as the base for the analysis. Our results of the firms’ intra-firm coordination for innovative processes showed us three different forms of intra-firm coordination and one specific mechanism for the intra-firm coordination. We hope that this thesis can provide insights to the innovation studies, defining the interactions was a first step and showcasing the intra-firm coordination, at a product development, might help the firms to understand the power that the interactions have to manage the knowledge sharing processes.

Texto completoIntroduction: In the interest of ensuring long-term food security and safety in the face of changing circumstances, it is interesting and necessary to understand and to take into consideration the environmental, social and economic aspects of food and beverage production in relation to the consumers’ demand. Besides, due to the globalization, the problems of long supply chains, information asymmetry, counterfeiting, difficulty for tracing and tracking back the origin of the products and numerous related issues have been raised such as consumers’ well-being and healthcare costs. Emerging technologies drive to achieve new socio-economic approaches as they enable government and individual agricultural producers to collect and analyze an ever-increasing amount of environmental, agronomic, logistic data, and they give the possibility to the consumers and quality control authorities to get access to all necessary information in a short notice and easily. Aim: The object of the research essentially concerns the study of the ways for improving the production process through reducing the information asymmetry, making it available for interested parties in a reasonable time, analyzing the data about production processes considering the environmental impact of production in terms of ecology, economy, food safety and food quality and build the opportunity for stakeholders to make informed decisions, as well as simplifying the control of the quality, counterfeiting and fraud. Therefore, the aim of this work is to study current supply chains, to identify their weaknesses and necessities, to investigate the emerging technologies, their characteristics and the impacts on supply chains, and to provide with the useful recommendations the industry, governments and policymakers.

Texto completoThis work aims to understand the main benefits, drivers and actors of Digital Transformation in the Agrifood sector. This phenomenon plays a crucial role for agribusiness, especially in leading to a more productive, sustainable, and environmentally responsible food production. The study focused on the potential application of Precision Agriculture Technologies (PATs) among Italian farm managers. This research has been divided into eight research projects aiming to investigate four major issues: (1) factors affecting the intention to adopt PATs; (2) sustainability of the investments in those technologies, (3) the role of the farmer as a Manager in the farm's innovation process, and (4) the role of the provider in the technology adoption process. The proposed methodology is original because it accounts for the data acquisition process of the combination of quantitative and qualitative approaches. As results, this work shows how (i) the adoption of PATs in Italy still depends on the socio-economic characteristics of the farm; (ii) the use of precision farming technology could enhance the profitability of the farm by improving the farm yield, reducing variables cost and improving the farm management; (iii) how the managerial capabilities of the farmer are fundamental to uptake the process of digital transformation; (iv) a strict collaboration between technology providers and farmers could lead to a successful introduction of a technology.

Texto completoFood safety and food security are crucial aspects in the growing and constantly changing food market. The first definition refers to hygiene and foodborne diseases prevention, the second refers to the security for a consumer to by a specific product and not a counterfeit. An improved traceability, based on blockchain systems, may help to prevent food safety and food security issues. Blockchain belongs to the distributed ledgers, a type of database in which each participant owns a copy of the same data and every change in a copy is automatically reflected on the other copies. It is designed to guarantee decentralization, transparency, immutability and traceability. As shown by a relevant number of projects that has been developed and applied, it suits to the food supply chain traceability. An improved traceability based on blockchain can also be useful at the market level. For instance, Italian sounding is the practice to use Italian words, colours (such as the Italian flag colours) and names to give an Italian appearance to a product, irrespective of its country of origin and its production method, to promote it. It affects different sectors, but the food sector is the most damaged. The present research is focused on the application of the blockchain to the traceability of the food supply chain, its impacts and its perception. Indeed, the application of these systems may have several advantages, but also negative impacts: the producers must accept to show transparency to the consumers, it may lead to a price increase (as the design and maintenance of a digital traceability systems have a considerable cost) and consumer profiling is an aspect that must be properly discussed. To assess if the Italian consumers may be interested in the use of blockchain traceability for food, a survey has been performed on 500 users. The asked questions concern their interest and knowledge towards traceability, blockchain technology, shopping preferences, the suggestion of food categories (e.g. meat, fish and others) currently requiring an improved traceability. Lastly, the willingness to spend more to buy food provided with digital traceability was evaluated. The results revealed that respondents are generally interested in food traceability, they usually know what blockchain and digital traceability are, they buy food mainly at supermarkets, they are interested in knowing the origin of the food mainly for meat, fish and dairy, they would rather buy a product provided with digital traceability system instead of an unprovided competitor and they consider acceptable a 10-15% cost increase for a digitally traced product. To complete the research, a concrete project/case study has been completely developed in collaboration with the innovative startup Franceschi srl, composed by Saporare and S|Trace. Saporare is an online shop of traditional Italian food and beverages (e.g. balsamic vinegar, honey, olive oil, wine) of small and medium sized producers and each product has a declaration of origin. The products will be traced with S|Trace, a blockchain-based traceability system provided with a web app for data upload, designed to ease the operation for the producers. Saporare acts as the third part in the supply chain, certifying the origin and the security of the products, but without substituting production disciplinaries or food control agencies: this makes the perfect use-case to study the application of the blockchain to the food supply chain. Lastly, considering both costs and complexity of the blockchain, a pipeline facilitating the choice of the right technology has been developed. In particular, the developed pipeline may help to define which type of blockchain could be useful for each food supply chain and when a blockchain could be really effective.

Initially, a comprehensive two-dimensional gas chromatography (GC×GC-MS) method was developed by testing several column configurations to analyse apples and peaches. In the second part of the Thesis, three new methods based on injection-port derivatization were developed. The first consisted on a targeted analysis of 17 glycosylated and non-glycosylated polyphenols in fruit and fruit juice samples. The second method was devoted to the analysis of HMF and patulin, two compounds used as markers of quality in the fruit juice industry. The last method developed in this part was focused on the free lipophilic fraction of fruit juices. In this case, a dispersive liquid-liquid microextraction (DLLME) preceded in-port derivatization. The third part was devoted to the analysis of volatile and semi-volatile compounds in several fruit-derived products, namely fruit fibres deriving from the juice industry and four samples of peach juices consisting in two varieties (yellow and red-fleshed) and two distinct processing procedures for each variety (freshly blended and commercial).

In the United States, many are critical of agricultural policies and economic incentives that support large-scale food production and the dominant actors in the mainstream agrifood system. Critics point out that at the same time agribusinesses and very large-scale farmers receive support, there are those in poverty who struggle to meet their food needs. Critics question what that relationship should be between civil society and the agrifood system. A variety of activities are addressing concerns of social injustices in the system. For example, participation is increasing in civic and urban agriculture. Civic agriculture is the interrelated activities of small-scale, socially and environmentally sound practices of food production and consumption that aim to increase community sustainability. Urban agriculture is food production in and near cities. By focusing on Kansas and the Kansas City metropolitan area, this dissertation addresses the following questions: How do the relations between civil society and the U.S. agrifood system impact the level of fairness in the system? To what extent are urban agricultural activities fostering fairness in the agrifood system, including access to fresh foods, civic engagement, and fulfilling careers, while also benefiting the environmental health of the city? Survey and interview data collected by a research team on agriculture in Kansas sets the context for my examination of urban agriculture in Kansas City’s urban core. In addition to participant observations and primary and secondary data analysis, I conducted 38 semi-structured interviews with growers (27), food advocates (4), community organizers (4), and governmental employees (3). In Kansas City, many of the activities and programs in place are building community, strengthening civil society, and promoting food justice for the poor and for people of color, for example, in food deserts, which are locales where people particularly face challenges in meeting their food needs. While some participants are more focused on their immediate communities and less so on overt widespread change, others feel a part of a social movement aiming to change the agrifood system. Diverse people from various social classes and races are increasingly becoming involved in growing food and food advocacy to expand fairness in the system.

Texto completoThis research work sets objectives that combine the principles of circular economy, bioeconomy and sustainability in the agrifood field, to identify strategies for the enhancement of agro-industrial waste through a typical approach of biorefinery applications The main focus is dedicated to the large productions of Cucurbitaceae, with particular reference to the cultivars of Citrullus Lanatus (watermelon) and Cucumis Melo (melon), since the agri-food sector represented by these primary crops generates huge quantities of waste materials along the entire supply chain “from farm to fork”. The key idea of the PhD project consists in the possibility of extending the value chain, which currently seems to be interrupted with the abandonment of waste products in the open field, or those generically devalued due to morphological non-compliance, for over-production or over-ripening, restoring its continuity through the transformation of recovered material. The challenges of product and process technological innovation for the agrifood sector, would allow the use of these materials for transformations in any direction, anyhow all oriented according to the program targets of the 2030 Agenda. While recognizing the strategic value of the whole context of change identified by the ONU program, we have chosen to seize some of the major challenges to turn them into great opportunities, always operating along the guidelines of the food&feed context, neglecting the aspects directly related to energy recovery from residual biomass and the enhancement through composting processes. Therefore, through effective fractionation steps starting from the selected matrices, it was possible to obtain: ● dietary fibers of cellulosic origin, either natural “as it is”, or bleached through treatments with H2O2, red fibers with a high lycopene content; ● lycopene from red fibers, and other natural pigments-dyes from other fractions and by-products from the exocarp; ● germplasm oil from Citrullus seeds, and ● proteic-starchy flour (residue of the oil extraction) from the kernel of the same seeds; ● acetification products of the sugary juice extracted from the endocarp of the watermelon; ● candying products starting from the watermelon mesocarp (albedo). For the extended characterization of the different fractions, we have applied several instrumental techniques, analytical and chemical-physical methodologies, including the proper preparation of the samples, which can be summarized as follows: UV-Vis spectroscopy both on samples in solid state and in solution, also for the evaluation of the color point with the CIELab method; chromatographic techniques GC-MS, SPME-GC-MS, HPLC-DAD, HPLC-MS; elemental analysis (CHNS); thermal analysis (TG/DTG/DTA/DSC); Water Holding Capacity (WHC); ICP-OES analysis for the evaluation of the metal content; morphological analysis using surface techniques (SEM). At the end of the PhD activities, we can take a critical look at the targets achieved. Extending the value chain to waste materials can make it possible to acquire competitiveness for the agrifood system, but only if adequate efforts are made for investments in research and innovation. The reported analysis describes some structural features of a production sector that, at a regional and national level, is related to the performance of an oversized agrifood system, since it tends to reject pre-waste resources that are still easily recoverable. Projecting these results, which express competitive potential, in a gritty productive horizon and of reasoned consumption, can guarantee even only a small effective contribution to global food sustainability.

Texto completoThis thesis fits on studies about sustainability of agrifood systems. It results from an academic effort to associate studies of ecologically based production and rural development, to the research on agrifood systems and the socio-technical transitions towards sustainability. The empirical research relies on two certification systems for organic production: a) the Participatory System recently implemented Brazilian federal government (2011) guarantees the right to certification of production through participatory social organization - data collected from two experiences in Southern of Brazil; and b) the Dutch system for implementation of the EU Organic Logo: corresponds to a third party system under the sole supervision of the Dutch company Skal Biocontrol - data collected from the experience of gardeners, ecological small-scale producers. We carried out a comparative study from field research with certification systems of organic production, taking into account: 1) similarities and differences on the organization of organic and ecologically based production on each country; 2) dynamics and organizational interactions between the various actors involved within certification systems in localized experiences. The results show the commitment of these actors with the construction of the agrifood sustainability in its multiple dimensions: productive diversity; health; fair markets; rights and access to land and water; and food sovereignty. Still, we argued that family farmers and organic farmers in small-scale production in both countries are committed to the certification systems for several reasons, not only for the sake of markets. Further, we argued that the participatory systems regulated in Brazil contribute to the recognition of small-scale production; also to build democratic governance on circuits of production, processing, distribution and consumption. In the Netherlands, the results show little benefit from certification systems of third party to the ecologically-based on small-scale production, and also that there is a tendency to abandon certification by those producers, if no changes take place. Finally, we argued that the agrifood sustainability is built through localized practices, and that, in Brazil and the Netherlands, certification systems only contribute for the food sustainability, while it gives scope to that small-scale producers and farmers conduct their practices and projects through a multilevel governance process of agrifood systems.

Texto completoO tema sustentabilidade está cada vez mais na ordem do dia. Os consumidores preocupam-se com a origem dos produtos, a forma como os produtos são processados, os impactos ambientais da produção e as condições laborais em que tais produtos são fabricados. Esta pressão por parte dos consumidores tem feito com que as empresas tenham vindo a desenvolver práticas sustentáveis. O presente estudo realiza uma análise detalhada da sustentabilidade nas cadeias de abastecimento agroalimentares líderes em sustentabilidade com o objetivo de identificar os principais fatores que permitem avaliar e monitorizar uma operação sustentável. Foi também identificado um conjunto de indicadores que abrange as três dimensões da sustentabilidade neste setor. Foi ainda possível verificar que as empresas não desenvolvem os seus relatórios todos da mesma forma e não reportam os temas da sustentabilidade da mesma maneira apesar de pertencerem ao mesmo setor. Os resultados obtidos demonstram que as empresas líderes em sustentabilidade, identificadas neste estudo, têm vindo a desenvolver práticas sustentáveis e comprometem-se a atingir objetivos sustentáveis que abrangem tanto a área económica, como a área ambiental e a social.
The theme of sustainability is increasingly on the agenda. Consumers are concerned about the origin of the products, how products are processed, the environmental impacts of production and the working conditions in which they are manufactured. This pressure from consumers has led companies to develop sustainable practices. The present study performs a detailed analysis of sustainability in the leading agro-food supply chains with the objective of identifying the main factors that allow to evaluate and monitor a sustainable operation. It was also identified a set of indicators that cover the three dimensions of sustainability in this setor. It was also possible to verify that companies do not develop their reports all in the same way and do not report the subjects of sustainability in the same way, although belonging to the same setor. The results show that the leading sustainability companies identified in this study have been developing sustainable practices and are committed to achieving sustainable objectives that cover both the economic, environmental and social area.

Texto completoAfter the outbreak of the 2008 financial crisis, recent events of international political econo-my seem to reveal the possibility of being watched the gestation of a new world order, where some countries – especially the BRICS (Brazil, Russia, India, China, South Africa) – are gra-dually leaving behind its peripheral condition and beginning to play an important role in the dynamics of global capitalism. China’s rise to the status of a great power brings enormous impacts and and yet unknown repercussions on the contemporary economic and political order. And given its trajectory the recent years, Brazil has been seen as an emerging power. However, there is still scarce research on agriculture, food and rural development in the BRICS. And particularly in Brazil almost nothing is known about these topics in China. With the general objecttive of comparatively analyzing the “rural development dynamics” emer-ging in Brazil and China through the different forms of insertion of their “agri-food systems” in the “international food regime”, this work aims to fill part of this gap. The research is inspi-red by Karl Polanyi’s “great transformation” thesis on the rise and fall of the “nineteenth libe-ral civilization”, organized around a system of self-regulated markets. We are supposed to be living something similar at the present time, with consequences on agriculture and food. In this sense, it is fundamental the author’s notion of “double movement”. On the one hand, a hegemonic movement, represented by the liberalization of national agricultural markets and globalization of agri-food systems, under the control of transnational agribusiness corporations, the food industry and large retailers. On the other hand, a counter-hegemonic movement, represented by the newly emerging rural development dynamics, involving the realignment of agriculture in nature and society to create new foundations for food production, distribution and consumption as an expression of strength, resilience and autonomy of peasants and family farmers. The research hypothesis is that the new rural development dynamics emerging in China and Brazil are part of a “countermovement”. They appear simultaneously, in the same historical epoch and in such different realities, because they represent responses to the agri-food question in a context of crisis of neoliberal global-ization. Methodologically, the work is characterized as a “comparative institutional analysis”. It is a study of large thematic, theoretical and historical amplitude, which by combining institutional analysis and comparative method seeks to understand the contexts, mechanisms and results of these phenomena. Among the main conclusions of the thesis, three stand out. First, the recent trajectory of China and Brazil are related to a series of institutional changes that resulted in the reconfiguration of their class structures, bringing changes in the correlation of forces between the political projects competing for the destinies of each country and possible deployments on the construction of a new economic and political world order. Second, the formation of the Brazil-China “soy-meat complex” encapsulates in many ways the ongoing changes in their agrifood systems and it is emblematic of a broader process of polycentric restructuring of the international food regime dynamics, but also creates contesta-tions, above all, linked to rising food scandals in China and the abusive use of agrochemicals in Brazil. And third, rural development dynamics have been driving new reproduction circuits for farming and food supply and demand, involving technical-productive and organizational practices of family farmers and peasants, interests formulated as ideas by the intellectual and adopted as public policies by the state, and processes of political struggle and construction of “new, nested markets” connecting production and consumption of food.

Texto completoLa 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.

Texto completoPollution 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

Essa dissertação abordou um movimento que se consolida na Europa e que tem sido discutido e difundido, principalmente na Itália, a abordagem da filiera corta. 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.

In the context of the agrifood system and the Brazilian political situation, since 2003 agroecology is a contemporary approach inserted into the construction of public policies and interrelated to rural development, food sovereignty and Human Right to Adequate Food. 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.

Texto completoAgriculture’s transition towards agrocology requires a radical transformation of production practices based on ecological principles, but it also requires radical changes within transformation, distribution and consumption practices and within advisory systems, public policies and research. In other words, it requires a profound reconfiguration of the whole agrifood system. In the Drome Valley (France), the high proportion of actors who consider organic agriculture as central in their development strategy and their involvement within the “Biovallée” project, suggest that an agroecological transition is in process and that the territorial scale might facilitate it. This thesis analyses the agricultural dynamics at the scale of this territory since the 1970s, in order to understand the transition mechanisms and to conceptualize them. Based on a framework inspired from the sustainable transition theories and on an ethnographic and pragmatic approach, it shows that a reconfiguration of the whole local agrifood system is indeed in process, and that it results from the interactions between a dominant sociotechnical configuration and two alternative ones which local actors have set up over time around two alternative paradigms. We analyze how actors succeed in changing the balance of power within the local agri-food system and how the territorial scale offers them some levers which do not exist on a larger scale. In this case, certain traditional actors and a diversity of initiatives allowed actors to progressively set up new forms of coordination, that is social or organizational innovations (rather than technological ones). Therefore the main issue shifts from thinking transitions based on the development of atechnological innovation, towards creating conditions in order to favour the coexistence of a diversity of initiatives that develop social innovations and to favour their interactions with the dominant system

A agricultura familiar desempenha importante papel na economia e na sociedade como fornecedora de alimentos de primeira necessidade e geradora de mercado consumidor. Com a crescente demanda do mercado por produtos diferenciados, as Indicações Geográficas (IGs) têm sido reconhecidas como uma ferramenta com capacidade de fortalecer a agricultura familiar à medida que ela garante a qualidade e a reputação de um produto, ligando-o à sua origem, bem como reduzindo as assimetrias informacionais e protegendo o território da ação de oportunistas. Considerando as dificuldades encontradas pelos agricultores familiares para acessar mercados, esta pesquisa analisou como os registros de IGs favorecem a coordenação do sistema agroalimentar de café na agricultura familiar e quais suas contribuições para o desenvolvimento territorial. Para tanto, foi realizada uma pesquisa exploratória de casos múltiplos em duas regiões brasileiras que possuem o registro de IG para o café e que apresentam elevado número de propriedades familiares: a Serra da Mantiqueira em Minas Gerais e o Norte Pioneiro do Paraná. A abordagem teórica que sustentou a análise da coordenação vertical está centrada na Nova Economia Institucional, com base no Ambiente Institucional e na Economia dos Custos de Transação, buscando verificar por meio da escolha da estrutura de governança, a minimização dos custos envolvidos na transação. Já a abordagem teórica dos Sistemas Agroalimentares Localizados auxiliou na compreensão da coordenação horizontal e suas contribuições para o desenvolvimento territorial. Os resultados apontaram que nos territórios pesquisados o registro de IG contribui, principalmente, para a coordenação horizontal na medida em que reforça os laços entre os atores sociais que compõem o território, o que pode vir a contribuir para o seu desenvolvimento.
Family farming plays an important role in the economy as a supplier and consumer of food and goods. Under the growing market demand for differentiated products, geographical indications (GIs) have been recognized as a tool capable of strengthening family farming as it ensures the quality and reputation of a product by connecting it to its territory, as well as reducing informational asymmetries and protecting the territory from opportunistic actions. Considering the difficulties faced by farmers to access markets, this research examined how the IGs favor the coordination of the family farmers in the coffee agrifood system and what are their contribution to territorial development. To this end, an exploratory study of multiple cases was carried out in two Brazilian regions with GI registration for coffee and with a large number of family farms: the Serra da Mantiqueira in Minas Gerais and the Pioneer North of Paraná. The theoretical approach that supported the analysis of vertical coordination is based on New Institutional Economics, as Institutional Environment and the Economy of Transaction Costs. The theoretical approach of Localized Agrifood Systems helped in understanding the horizontal coordination and their contribution to territorial development. The results indicated that GI registrations contribute mainly to the horizontal coordination as it strengthens the links between social actors within the territory leading to local development.
