Organic Farming and Rural Transformations in the European Union: A Political Economy approach

Konstantinidis, Charalampos 01 September 2012 (has links)
This dissertation investigates the impact of organic farming for achieving the environmental and social objectives of sustainability in Europe over the past 20 years. Organic farming is considered the poster child of rural development in Europe, often seen as a model of the integration of small-scale production with environmental considerations. Since this model runs counter to the logic of developing capitalist structures in agriculture, I revisit the Marxian predictions regarding the "agrarian question". Furthermore, I trace the discursive changes in support of small-scale production in the EU's Common Agricultural Policy (CAP), and assess whether small farms have improved their situation under the revised CAP. Subsequently, I use statistical analysis in order to assess the socio-economic and the environmental consequences of the rise in organic farming. Contrary to what is often assumed, organic farms in Europe display larger average sizes and lower rates of labor intensity than their conventional counterparts, casting doubts on the efficacy of organic farms to allow family farmers to remain in the countryside as high-value producers. I argue that this this development should be viewed as further evidence of the "conventionalization" of organic farming. In order to explain the process which led to such an outcome, I proceed to explain the different ways through which organic farms could overcome traditional problems which impeded the capitalist development of agriculture. Regarding the environmental implications, I evaluate the rise of organic farming by assessing its impact for different countries' overall pesticide and fertilizer intensity. My results are mixed, with higher organic shares being correlated with decreased application of fertilizer, but less significant results for pesticide intensity.

Adoption of non-traditional enterprises by Virginia farmers

Zhou, Xiaofeng 11 July 2009 (has links)
This study investigates the role of non-traditional enterprises in rural economies and attempts to understand farmers’ decision to adopt non-traditional enterprises. Three separate mail surveys were conducted to collect socio-economic data from biological and organic, Angora goat, and ginseng farm enterprises. Descriptive statistics, Pearson χ² tests, and multinomial logit models were used to accomplish the objectives of the study. The analysis focuses on biological and organic, and Angora goat enterprises. The results of the analysis show that the principal operators of these enterprises were significantly younger, better-educated, better-off, and more likely to be a female in comparison to all Virginia farmers. The majority of farm operators came from non-rural backgrounds and their principal occupation is not farming. Only a very small percentage cited economic factors as the most important reason for starting the non-traditional enterprises. The most common information source used for planning and developing these new enterprises is books, magazines, or newsletters. The majority of respondents in both the biological/organic and Angora goat surveys did not perform any feasibility analyses prior to beginning their non-traditional enterprises. The farmers rated production and marketing as their major problems. In general, the majority of biological and organic farms and Angora goat farms were not profitable in 1993, and the income from these enterprises contributed very little to household income. However, it was found that biological and organic enterprises have played an important role in the economic survival of farmers with financial obstacles. The majority of farmers in the samples saw a bright future for their products. / Master of Science
