FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / It aims to analyze the socioeconomic profile of producers of irrigated fruit in the Cariri and measure the technological level, identifying the factors that influence each level. The measurement of technological index of fruit growers allows you to identify the level of technology used by producers. Have the technical efficiency scores of caririenses fruit growers and the identification of the effects of socioeconomic variables on efficiency levels allowed capture the impact of these determinants along different points of the conditional distribution of technical efficiency. In preparing the technological index was used factor analysis, and to measure the index of efficiency scores were applied in determining the analysis of data envelopment analysis (DEA) models and quantile regression. Came indicators of primary sources, collected in 2014, directly, with 86 growers located in six municipalities of the Cariri. The results show that in most cases, the growers (53.49%) have only to primary education, and only 16.28% can only sign his name. You can still see that 31.40% of producers have secondary education and that is down the number of illiterate farmers (3.49%) and they have 30-50 years of age (66.67%) and also that 75 , 68% of growers have over five years experience in the activity. The results also show that 42.66% of the fruit growers of the region not participating unions have no access to any type of credit; 72.73% of these already, participating cooperatives or associations, hold some kind of credit. For the technological indexes classified as very low, there were two growers, 30 of them were considered low-tech, 53 fruit growers have considered average index and fruit grower demonstrated considered high index, 0.62 to 0.78, with relative frequency of 1, 16%. There were no fruit growers with very high rates for technology adoption. The variables that contributed most to indicate adoption of technological improvements in that index were Total Area, Gross Income and Total Production, result justified by the increased variance indicated by the data, a total of 24.058%, represented by the factor 1 (intensive Productivity) technology. The quantile regression was estimated, considering the technical efficiency scores obtained in the constant returns to scale model, the results show that the explanatory factors of technical efficiency for the group of more efficient producers are important in explaining the efficiency of this group. For the less efficient growers group, it is observed that among the six explanatory variables, only management index, credit and education played irrelevant role in explaining variations in technical efficiency level, since the coefficients of these variables were not statistically significant, in this case, there is no difference between fruit growers with access to credit and those without and between grade levels, ie, if the producer has secondary or higher education or do not have that level of education. / Objetiva analisar o perfil socioeconÃmico dos produtores de fruticultura irrigada na regiÃo do Cariri e mensurar o nÃvel tecnolÃgico, identificando os fatores que mais influenciam cada nÃvel. A mensuraÃÃo do Ãndice tecnolÃgico dos fruticultores permite que se identifique o nÃvel de tecnologia utilizado pelos produtores. Jà os escores de eficiÃncia tÃcnica dos fruticultores caririenses e a identificaÃÃo dos efeitos das variÃveis socioeconÃmicas sobre os nÃveis de eficiÃncia permitiram captar os impactos desses determinantes ao longo de pontos distintos da distribuiÃÃo condicional da eficiÃncia tÃcnica. Para a elaboraÃÃo do Ãndice tecnolÃgico foi empregada a anÃlise fatorial, e para mensurar o Ãndice dos escores de eficiÃncia foram aplicados na anÃlise determinante os modelos de anÃlise envoltÃria dos dados (DEA) e de regressÃo quantÃlica. Os indicadores provieram de fontes primÃrias, colhidas em 2014, diretamente, com 86 fruticultores, localizados em seis municÃpios da regiÃo do Cariri. Os resultados mostram que em sua maioria, os fruticultores (53,49%) sà possuem atà o ensino primÃrio, sendo que apenas 16,28% conseguem assinar somente o nome. Ainda se pode perceber que 31,40% dos produtores possuem ensino secundÃrio e que à baixo o nÃmero de produtores analfabetos (3,49%) e eles tÃm de 30 a 50 anos de idade (66,67%) e ainda, que 75,68% dos fruticultores tÃm mais de cinco anos de experiÃncia na atividade. Os resultados tambÃm mostram que 42,66% dos fruticultores da regiÃo que nÃo participam de cooperativas nÃo tÃm acesso a algum tipo de crÃdito; jà 72,73% destes, que participam de cooperativas ou associaÃÃes, detÃm algum tipo de crÃdito. Para os Ãndices tecnolÃgicos classificados como muito baixo, houve dois fruticultores, 30 deles foram considerados de baixa tecnologia, 53 fruticultores apresentam Ãndice considerado mÃdio e um fruticultor demonstrou Ãndice considerado alto, de 0,62 a 0,78, com frequÃncia relativa de 1,16%. NÃo foram encontrados fruticultores com Ãndices muito altos para adoÃÃo de tecnologia. As variÃveis que mais contribuÃram para indicar melhorias de adoÃÃo do nÃvel tecnolÃgico do referido Ãndice foram: Ãrea Total, Renda Bruta e a ProduÃÃo Total, resultado justificado pela maior variÃncia apontada pelos dados, num total de 24,058%, representadas pelo fator 1 (uso intensivo da tecnologia Produtividade). A regressÃo quantÃlica foi estimada, considerando os escores de eficiÃncia tÃcnica obtidos no modelo de retornos constantes de escala, cujos resultados mostram que os fatores explicativos da eficiÃncia tÃcnica para o grupo de produtores mais eficientes sÃo importantes para explicar a eficiÃncia desse grupo. Para o grupo de fruticultores menos eficientes, observa-se que dentre as 6 variÃveis explicativas, apenas Ãndice de gestÃo, crÃdito e escolaridade desempenharam papel irrelevante para explicar variaÃÃes no nÃvel de eficiÃncia tÃcnica, jà que os coeficientes destas variÃveis nÃo se mostraram estatisticamente significantes, neste caso, nÃo hà diferenÃa entre os fruticultores com acesso ao crÃdito e os que nÃo possuem e entre os nÃveis de escolaridade, ou seja, se o produtor possui ensino secundÃrio ou superior ou nÃo tem esse grau de instruÃÃo.

In this Master of Arts Thesis in Anthropology I examine the controversy in the Okanagan Valley over the introduction of GM seed technologies into local agricultural processes. I explore via a multi-sited ethnography how local fruit farmers in this region view GM seed technologies and their perception of how these technologies will impact their farming practices. I argue that (a) the use of GM seeds as currently regulated in Canada threatens to erode farmers' local knowledge of plant breeding and that (b) this erosion is of consequence not only to local farmers but to society generally because the environmental knowledge and skills possessed by local farmers is crucial to the protection of biodiversity, environmental sustainability, and food security.
