Resumo: Aiming to understand interrelations surrounding maize culture in El Salvador, the present work addresses white maize agri food system in Ciudad Arce. To do so, this thesis has used localized agrifood systems as theoretical framework. Thereof, historical, technical, institutional and food aspects compounding the localized agrifood system have been studied. Seemingly, this thesis has carried out a dense fieldwork, spreading through direct interviews with 82 maize producers in Ciudad Arce. Additionally, a number of actors, both public and private, have been interviewed, including: Rural extentionists, researchers, inputs providers, food retailers among others. This thesis begins with a theoretical analysis of territory. Thereof, the territorial perspective developed in the present work has been enriched from Geography, since it was originally within this science where territory emerged and where it has been more rigorously studied. This theoretical discussion of territory has paved the way to analyze its appropriation by productive agglomeration approaches such as: Industrial districts, clusters, local productive arrangements, local productive systems, rural agoindustry and localized agrifood systems. Given our above mentioned analysis on territory, it is highlighted that all these theoretical perspectives conceive the territorial concept with a positive bias, leaving aside the historical power relations accompanying territory from a geographical perspective. Subsequently, and given a lack of detailed and trustworthy statistics and databases in El Salvador, this thesis profoundly describes maize producers in Ciudad Arce. To do so, the framework of localized agrifood systems is implemented, describing producers in terms of their historical, technical, institutional and food peculiarities. This characterization paved the way to conceptualize and analyze how the maize localized agrifood system is structured in Ciudad Arce. Besides this conceptualization and analysis, the present work has exposed power relations at different levels, some of which are not conscripted to the usual economic and political arena. Hence, it has been possible to identify and discuss at least two power relations in each of the four dimensions that form the above mentioned localized agrifood system (LAFS). This qualitative analysis set the way to move onto a quantitative discussion. Within it, a system of four regressions (one for each LAFS dimension) was performed to predict and quantify maize productivity variations. Likewise a system of four regressions was used to predict and quantify variations in total production of this cereal. In general terms, regressions having productivity as dependent variable showed more modest results. Afterwards, another multiple regression was used to predict the variations of maize production including variables from all four different dimensions form the LAFS. At this point selected variables were combined into only one multiple regression in order to integrate the previous isolated dimensions. This regression was able to predict 83% of variations in maize production (R²: 0.830/ R² Adjusted: 0.782). These results identified many variables that influence total production, among the three most relevant in decreasing importance are: Area planted, commercial motivation to produce maize and the possession of an irrigation system. At the end, this thesis elaborates final considerations at both theoretical and practical level. Likewise, it also points to new research lines.

Para tal fin, el presente trabajo se ha valido de los sistemas agroalimentarios localizados como marco teórico. Con ello, se ha estudiado aspectos históricos, técnicos, institucionales y alimenticios del mencionado sistema. De tal suerte, esta tesis se ha valido de un nutrido trabajo de campo, que abarcó entrevistas directas con 82 agricultores que producen maíz, además de un número elevado de actores públicos y privados relacionados al tema, entre ellos: extensionistas rurales, investigadores, proveedores de insumos, comerciantes agrícolas. Esta tesis parte de una revisión teórica que aborda el territorio como concepto central. En tal sentido, la visión del territorio ha sido nutrida con aportes desde la geografía, ya que en esa ciencia se ha tratado históricamente este concepto de forma más rigurosa. La discusión sobre el territorio ha permitido evaluar su aplicación a la hora de ser retomada por enfoques teóricos que estudian aglomeraciones productivas, como los distritos industriales, los clúster, arreglos productivos locales, sistemas productivos locales, agro industrias rurales y los propios sistemas agroalimentarios localizados. A la luz de nuestro análisis sobre el territorio, se ha podido evidenciar que todos estos enfoques teóricos se apropian del territorio con un sesgo positivo, dejando de lado las históricas relaciones de poder circundantes a este concepto geográfico. Posteriormente, ante una ausencia de datos pormenorizados y estadísticas confiables, se caracteriza de forma profunda a los agricultores que producen maíz en Ciudad Arce De tal suerte, y al amparo del marco teórico de los sistemas agroalimentarios localizados, se destacan características históricas, técnicas, institucionales y alimenticias de los agricultores. Esto da paso a poder conceptualizar y analizar, cómo está formado el sistema agroalimentario del maíz en Ciudad Arce. Paralela a esta conceptualización y análisis, se ha explicitado cuáles son las relaciones de poder en diversa escala que han sido identificadas. De tal suerte, ha sido posible problematizar al menos dos relaciones de poder en cada una de las diferentes dimensiones del SIAL. Todo este análisis de cuño más cualitativo, da paso a un análisis cuantitativo. Al respecto, se realiza en primer lugar un sistema de cuatro regresiones (una por cada dimensión del SIAL) para predecir y cuantificar las variaciones en la productividad del maíz. Similarmente se emplea otro sistema de cuatro regresiones teniendo como variable dependiente producción de maíz. En términos generales, las regresiones que tienen a la productividad del maíz como variable dependiente, muestran resultados mucho más modestos. En un segundo momento, se opta por realizar una regresión múltiple que integre variables de las diferentes dimensiones abordadas, mismas que habían sido estudiadas hasta ahora de forma aislada. Esta regresión integrada consigue dar cuenta del 83% (R²: 0.830/ R² Ajustado: 0.782) de las variaciones en la producción. Se pudo identificar numerosas variables que influían en la producción total de maíz, siendo las tres más importantes en orden decreciente: superficie plantada, motivación para la producción de maíz es el comercio y la posesión de un sistema de riego. Finalmente, la tesis concluye con consideraciones a nivel teórico y práctico, no sin antes apuntar sobre nuevas líneas de investigación a ser exploradas.application/pdfspaDesenvolvimento ruralProduto agrícolaMilhoRelações sociaisSistemas agráriosMaizeProductive agglomerationsLocalized agifood systemsEl SalvadorAglomeraciones productivasSistema agroalimentario localizadoMaízCiudad ArceSistema agroalimentario del maíz blanco en Ciudad Arce, municipio de El Salvadorinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisUniversidade Federal do Rio Grande do SulFaculdade de Ciências EconômicasPrograma de Pós-Graduação em Desenvolvimento RuralPorto Alegre, BR-RS2018doutoradoinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFRGSinstname:Universidade Federal do Rio Grande do Sul (UFRGS)instacron:UFRGSORIGINAL001078120.pdfTexto completo (espanhol)application/pdf2838505http://www.lume.ufrgs.br/bitstream/10183/183066/1/001078120.pdf21defcfbdb2950bae681972c7b822f92MD51TEXT001078120.pdf.txt001078120.pdf.txtExtracted Texttext/plain627433http://www.lume.ufrgs.br/bitstream/10183/183066/2/001078120.pdf.txt9abebe322782341d364757c5fd181993MD52THUMBNAIL001078120.pdf.jpg001078120.pdf.jpgGenerated Thumbnailimage/jpeg1074http://www.lume.ufrgs.br/bitstream/10183/183066/3/001078120.pdf.jpg725304253ba82ee1e77bd8788727da64MD5310183/1830662021-05-26 04:35:53.112885oai:www.lume.ufrgs.br:10183/183066Biblioteca Digital de Teses e Dissertaçõeshttps://lume.ufrgs.br/handle/10183/2PUBhttps://lume.ufrgs.br/oai/requestlume@ufrgs.br||lume@ufrgs.bropendoar:18532021-05-26T07:35:53Biblioteca Digital de Teses e Dissertações da UFRGS - Universidade Federal do Rio Grande do Sul (UFRGS)false
