Reclaiming The Future Through Small-Scale Agriculture: Autonomy And Sustainability In The Caribbean, Dana M. Conzo

Doctoral Dissertations

My dissertation, “Reclaiming the future through Small-Scale Agriculture: Autonomy and Sustainability in the Caribbean,” is a political-economic analysis of land politics, foodscapes and foodsheds, and small-scale agricultural activities in plantation economies on the Caribbean island of St Kitts. Using ethnographic and geographic methods, such as participant observation, interviews, social network analysis, and foodshed mapping, I investigate the cultural and economic niche of local farmers, documented and analyzed the island’s foodshed, and provide a historical and economic background of St Kitts to link historical processes to contemporary spatial organization and agricultural practices.

Effects Of Switchgrass Related Land-Use Changes On Aquatic Macroinvertebrates, Latha Malar Baskaran

Doctoral Dissertations

This research examines if switchgrass-based land-management practices have the potential to influence aquatic macroinvertebrates through changes in stream flow and water quality. The number of taxa in Ephemeroptera, Plecoptera, and Trichoptera orders (EPT taxa richness/EPT-TR) is analyzed as an aquatic macroinvertebrate bioindicator in the context of regional environmental effects, and changes in stream flow and water quality. This dissertation is structured as three manuscripts that link together to address the overall research question.

The first manuscript focuses on identifying regional environmental variables that influence EPT-TR across ecoregions in Tennessee. The influences of temperature, precipitation, geology, soil, stream flow and velocity …
