Since recent years, while issues of environmental protection and green industries have been discussed globally, Taiwan¡¦s agricultural industry has attracted much attention. The local and central governments alike began to promote many agri-facilitating strategies and measures, such as agri-tourism, green technology, and renovation of rural villages. However, on the other hand, the farming population keep on declining through the years, as percentage which youngsters choose farming as an occupation remain significantly low. The current research explored the contemporary Taiwanese college student¡¦s perception of farm living, cognition of agricultural industries, their intentions to choose farming career in various situations, and factors influencing their occupation decisions. The theoretic constructs involved in the present study included: perception of rural living, attitude toward agriculture, knowledge of agricultural industries, values of occupation and intention to join farming. In addition, family supports and understanding of government¡¦s promotion for farming were included also as two practical considerations. The valid empirical sample of the study are 543 college students randomly collected from five public or private universities in southern Taiwan. Data analysis revealed that the reliability and validity of the measuring scales all reached adequate standards, showing good quality of the data. In the research results, regarding the interactive relationship among the main variables, most of the hypothesis obtained supports from the data with statistically significance. Yet, only a few clues could be seen vis-à-vis the higher level of variable relationships, due to the limitation of the applied analysis tool of regression.

In recent years the three Prairie Pools have actively expanded their primary operations to include a number of investments both within and outside of the agricultural sector. The Pools' investment strategies are economically interesting because they are being pursued within the context of a co-operative organizational structure which requires that the users of the cooperative business also own, control, and benefit from its operations. This thesis examines the possible economic incentives agricultural co-operatives may have to invest in vertically integrated and diversified activities using the case of the Western Canadian co-operative elevator companies as an example. The analysis undertaken in this thesis is structured in two ways. First, the economic literature regarding co-operative formation and conventional firm expansion is surveyed. This analysis suggests that an important difference between vertically integrated investments and diversified investments is that they are motivated by the realization of distincly different sets of economic benefits for the co-operative firm and its members. It is argued that co-operative vertical integration can convey benefits to members indirectly through the market, in the form of increased producer margins and improved market access. However, these benefits may not impact the "bottom line" of the co-operative firm. Diversification can, on the other hand, provide a co-operative with direct monetary benefits in the form of improved financial performance and increased profits, which can translate into increased patronage refunds available to members. The second component of this analysis involves the development of a simulation model to examine the implications of an additional hypothesis proposed to explain co-operative expansion. The proposed hypothesis is based on the notion that perhaps the indirect market benefits from cooperation and co-operative expansion are being undervalued. This undervaluation can result in a preoccupation with the monetary benefits from co-operative business, and may therefore cause a bias towards diversified investments. The model developed in this thesis illustrates that, although such a bias may improve a co-operative's rate of return, it may also result in significant opportunity costs for agricultural producers due to a decrease in a co-operative's pro-competitive effect on primary markets.

Os abatedouros e frigoríficos caracterizam-se por agroindústrias potencialmente poluidoras devido a carga orgânica componente dos efluentes líquidos e resíduos sólidos gerados em seu processo. Para a minimização do impacto ambiental gerado por estes empreendimentos faz-se necessária a implementação de processos de tratamento que possibilitem a redução da carga orgânica, a transformação de resíduos em produtos de valor agregado e o aproveitamento energético. A implementação de biodigestores para o tratamento dos resíduos sólidos e efluentes líquidos gerados nos frigoríficos de suínos é uma opção interessante, haja visto o processo de digestão anaeróbia que compõe o sistema e os benefícios possíveis com sua aplicação. Neste intuito, o presente trabalho teve como objetivo a avaliação de um digestor anaeróbio de fluxo contínuo, em escala real, utilizado para o tratamento dos resíduos sólidos e efluentes líquidos oriundos do processo. Para isto procedeu-se a caracterização físico-química dos substratos de alimentação do biodigestor bem como do afluente e efluente do sistema, além da realização de análises com o intuito de avaliar as características do biofertilizante e do biogás originados no processo. Os resultados demonstraram que o substrato de alimentação do biodigestor é composto por diversas origens e, cada qual, possui características físico- químicas específicas e diferenciadas porém, quando unificadas, propiciam o desenvolvimento de um ambiente suscetível ao desempenho da digestão anaeróbia. Avaliando a eficiência do sistema em geral, considerando os valores obtidos nas análises do afluente e efluente do mesmo, observou-se que alguns parâmetros apresentam eficiência enquanto, outros, resultaram em aumento de concentração. Este fato pode ter sido desencadeado por fatores externos ao sistema. Quanto ao biofertilizante oriundo do biodigestor, foi caracterizado como resíduo sólido não inerte sendo possível, com algumas restrições, a sua aplicação em solo. O biogás, por sua vez, apresentou concentrações interessantes de metano, sendo, portanto, passível de utilização em diversos processos industriais. / Slaughterhouses are potentially polluting agricultural industries due to the organic load present in the wastewater and solid waste generated in the process. To minimize the environmental impact generated by this type of activity, it is necessary to provide a treatment processes that enables the reduction of the organic matter present in slaughterhouse waste, transforms waste into value-added products and exploits energy use efficiently. The implementation of biodigesters to treat solid waste and wastewater generated in slaughterhouses is an interesting option, given the anaerobic digestion process that makes up the system and the possible benefits it provides. Therefore, the present study evaluated the efficiency of an anaerobic continuous flow digester, in real scale, used for the treatment of solid waste and liquid effluents from the process. In order to do so, physicochemical characterization of the digester feed substrates, as well as, characterization of the influent and effluent of the system were performed. In addition, analyzes were executed to evaluate the characteristics of the bio-fertilizer and biogas originating in the process. The results showed that the digester feed substrate is composed of various origins and, each has a specific and distinct physicochemical characteristic, but when these different characteristics are combined they favor the development of an environment prone to the performance of the anaerobic digestion. By assessing the overall system efficiency, while considering the values obtained for the influent and effluent analysis, some parameters were considered efficient, whereas others result in the increase of concentration. This may have been triggered by factors which are external to the system. The bio-fertilizer originating from the digester was characterized as non-inert solid waste, which might require certain restrictions in its application in soil. Biogas, in turn, presented interesting methane concentration and is therefore likely to be used in various industrial processes.

Em se tratando do Brasil, há evidências que esse tipo de problema não ocorre de modo significativo nos tempos atuais. Diante desse fato, surge o objetivo principal deste estudo: verificar se a ausência de competição no Brasil entre a produção de etanol e a produção de alimentos ocorre devido ao aumento de eficiência produtiva no setor agropecuário ou se dá pela expansão da produção de cana-de-açúcar e de alimentos em áreas onde ocorre desmatamento da vegetação nativa. Para alcançar tal objetivo, o presente trabalho contará com uma metodologia baseada no conceito de elasticidade, na qual os valores médios de variáveis referentes ao cultivo de determinadas commodities alimentares serão comparados com os respectivos resultados referentes ao cultivo de cana-de-açúcar / The possible negative impact of biofuel production on food security has always been an object of study in academic circles since the 1970s, when the international price of oil has risen considerably. In the case of Brazil, there is evidence that this type of problem does not occur significantly in recent times. Given this fact, the aim of this study arises: verify that the lack of competition in Brazil between ethanol production and food production occurs due to increased production efficiency in the agricultural sector or is by expanding production of sugarcane and food in areas where there is deforestation of native vegetation. To achieve this goal, this paper will include a methodology based on the concept of elasticity, in which the average values of variables related to the production of certain food commodities will be compared with the corresponding results related to the production of sugarcane

Abrangendo um território composto por dezessete municípios, esta área inicialmente introduziu a cana-de-açúcar para a produção de aguardente. A primeira agroindústria do setor sucroalcooleiro surgiu em 1951, mas foi a partir de políticas do Instituto do Açúcar e Álcool (IAA), com o PROÁLCOOL (1975), que houve a implantação de destilarias com a finalidade de produzir álcool carburante. Após 1980, surgem sindicatos no EDR de Ourinhos ligados ao setor sucroalcooleiro, que se engajam na luta a favor dos direitos dos trabalhadores em relação aos donos dos meios de produção desse setor. O trabalhador, por sua vez, encontra-se cada vez mais pressionado pelas agroindústrias sucroalcooleiras e procura adequar-se ao novo perfil do mercado de trabalho (após 1990), participando de programas de qualificação profissional e buscando a qualidade total, quesitos mínimos para a obtenção de certificados de qualidade (como o ISO 9001) pelas empresas. / This work has for purpose to contemplate a study of Agrarian Geography in the Office of Rural Development (EDR) of Ourinhos, created through public politics of the State of Sao Paulo, whose main agricultural culture is the sugar-cane. Covering a territory composed by seventeen municipal districts, this area initially introduced the sugar-cane for the production of brandy. The first agricultural industry of the sector of sugar and alcohol appeared in 1951, but it was starting from politics of the Institute of the Sugar and Alcohol (IAA), with PROÁLCOOL (1975), that there was the implantation of distilleries with the purpose of producing alcohol fuel. After 1980, unions appear in EDR of Ourinhos linked to the sector of sugar and alcohol, and they are engaged in the fight in favor of the workers' rights in relation to the owners of the means of production of this sector. The worker, on the other hand, is more and more pressed by the agricultural industries of sugar and alcohol and tries to adapt himself to the new profile of the job market (after 1990), participating in programs of professional qualification and looking for the total quality, minimum requirements for the obtaining of quality certificates (as ISO 9001) by the companies.
