The Edible Landscape: Plant Breeding, Farming, And Sustainbility In Northwest Portugal, Joseph Blanchard Powell
LSU Doctoral Dissertations
This dissertation is an ethnographic analysis of a participatory plant breeding project in northwest Portugal. Participatory plant breeding (PPB) is a crop enhancement strategy that brings farmers and plant breeders together in the effort to conserve crop genetic resources in-situ, improve yield, and increase the overall agricultural sustainability in agriculture. One strategy in PPB calls for plant breeders to spend considerable time on working farms to understand better farmers’ knowledge and skill, and to survey the existing crop genetic diversity within the existing resource limitations on farms. Although there are clear social implications for PPB, the bulk of PPB evaluative …

Integrated Sustainability And Resiliency Assessment Methodology For The Design Of Single-Family Residential Structures Subject To Wind And Flood Hazards, Elizabeth Chisolm Matthews
LSU Doctoral Dissertations
Sustainability and resiliency have become important in shaping the criteria in performance-based design objectives in the recent past and will continue to shape future design as climate change impacts and disasters become more prevalent. While much work has been carried out in developing tools to aid in sustainable and resilient performance-based design there is still much work to be done. It is evident that while sustainability and resiliency have mutual advantages there are also inherent conflicts between the two design approaches. Some of the conflict relates to the robustness required of resilient design, which may have higher environmental impacts than …

A Spatial Dynamic Model Of Population Changes In A Vulnerable Coastal Environment, Kenan Li
LSU Doctoral Dissertations
Achieving coastal sustainability in low-lying coastal areas is a great challenge. This study developed a spatial dynamic model to study the coupled natural-human responses in the form of population changes in the Lower Mississippi River Basin region. The goal was to identify the key social-economic factors (utility) and selected environmental factors (such as hazards damage, elevation, and subsidence rate) that affect population changes, as well as how population changes affect the local utility and the local environment reciprocally. The study area was partitioned into the “north’ and the “south” by a hypothetical boundary to test the differences of the emergence. …
