Cotton production came to a halt in Southern Illinois in 1974 after the last crop was harvested. Many factors went into the death of cotton in Southern Illinois. My dissertation addresses the factors that halted cotton production in 1974, and new technologies that will enable farmers to grow cotton again in 2019. Temperature and rainfall are two important factors that affect the growth of cotton. Once cotton is re-introduced into Southern Illinois, an infrastructure with a well-trained workforce will need to be in place to sustain this new industry. This study was motivated by three research goals and questions: (1) Have Southern Illinois temperatures increased or decreased over the last 50 years? Specifically has Growing Degree Days or Heat Units increased over the last 50 years creating a more suitable environment for cotton production in Southern Illinois? (2) Was rainfall a limiting factor in the death of cotton in 1974 and the revival in 2018? How has rainfall changed in Southern Illinois over the last 50 years? (3) What impact would the cotton industry have on the Southern Illinois workforce? Specifically, what would education and training for a new cotton industry entail?

Cette thèse étudie l’efficacité technique, la productivité et la compétitivité des principaux pays producteurs de coton. Un premier chapitre décrit la compétitivité internationale de façon générale et les stratégies commerciales pratiquées. Les structures productives en Afrique Subsaharienne sont traitées au deuxième chapitre, car considérées comme les plus faibles. Le secteur du coton étant retenu comme cadre d’étude au troisième chapitre. Une étude économétrique est faite afin de mettre en exergue les déterminants de la performance à l’exportation du coton. Les deux derniers chapitres portent sur l’analyse et la mesure de l’efficacité technique et la productivité globale des facteurs tant théoriques qu’empiriques. La méthode d’enveloppement des données est mise en évidence suivie d’une analyse économétrique. Cette étude est réalisée afin de mettre en place une politique de production efficace et de compétitivité. A cette fin, elle propose un nouveau visage organisationnel en termes d’implications de politiques économiques pour contribuer à revitaliser le secteur cotonnier considéré comme moteur du développement économique en Afrique. / This thesis aims to study the technical efficiency, the productivity and the competitiveness of the main cotton producing countries. In a first chapter, it describes globaly the international competitiveness and the practised commercial strategies. The productive structures in Sub-Saharan Africa are examined in the second chapter, because they are considered as the weakest. The third part deals with the branch of the coton. An econometric study is led in order to highlight the determiners of the performance in the cotton export. The last two chapters concern the analysis and the measurement of the technical efficiency and the global productivity of theoretical and empirical factors. The method of the data envelope is revealed, followed by an econometric analysis. This study is realized to set up a policy of effective production and competitiveness. In this purpose, she proposes a new organizational face in the implication of economic policies to contribute to revitalize the cotton branch, which is considered as a driving element of the economic development in Africa.
