This dissertation examines the relationships between nations' positions within the global food and agriculture system and the environmental degradation associated with their agricultural activities. Using a cross-national analysis,each nation's position in the world-system,the degree to which they are developed,and the degree to which their economy is predicated upon the production of agricultural products for global markets is operationalized. These political-economic factors are then examined to test the influence of three different forms of environmental degradation that are all linked to agricultural production (Biodiversity loss,nitrous oxide emissions from agriculture,and methane emissions from agriculture). These three different analyses will constitute the three separate empirical chapters. Taken as a whole,this dissertation examines broad patterns of international power relations,linked processes of development and agricultural dependence,and the environmental degradation that results from these processes. This work represents a contribution to both environmental sociology as well as our broader understanding of the social dynamics that structure and lead to environmental degradation. Specifically,by connecting agricultural dependency with environmental degradation,it provides a systematic exploration of how the global food and agriculture system is structured in a way that concentrates environmentally degrading agricultural processes into developing nations.
