Short rotation woody crops (SRWCs) are renewable biomass feedstocks that can be conveniently established in the landscape to conserve soil and water, recycle nutrients, and sequester carbon, especially on marginal lands such as degraded agricultural fields. They are purpose-grown trees that could be a part of the renewable energy solution in the United States, especially in the Southeast where agriculture and plantation forestry is prevalent and economically important. This study evaluated the growth, biomass productivity, carbon storage, and soil health benefits of establishing American sycamore SRWCs on degraded agricultural fields in the Piedmont and Coastal Plains regions of North Carolina. The first chapter is a synthesis of the regional implications of integrating SRWCs into conventional agriculture practices in the southeastern United States. The review focused on the growth and productivity of various SRWCs species in the region, ecosystem benefits of the integrated system, economic and social benefits of the integrated system, and the role of remote sensing and GIS technologies in studying the integrated system. This review chapter leads to the other chapters in this dissertation where I studied the ecological and environmental sustainability of American sycamore SRWCs (Chapters 2 and 3), the use of remote sensing technologies to estimate aboveground biomass of Sycamore SRWCs (Chapter 4), and the social influences of adopting a new farming system such as SRWCs in North Carolina (Chapter 5).In the second chapter, I investigated the effects of planting design, coppicing, age, and site characteristics on the growth, survival rate, biomass productivity and biomass partitioning of American sycamore established on degraded agricultural fields in the Piedmont and Coastal Plains regions. I also investigated the effects of land use (sycamore and cornfield) on total soil carbon stock and other soil properties. In the third chapter, I looked at the impacts of three planting density treatments (10,000, 5000, and 2500 trees per hectare (tph)) on the distributions of sycamore SRWCs coarse and fine root biomass and how it affects the soil physical properties in each density. For the fourth chapter, I investigated the utility of publicly available airborne Light Detection and Ranging (LiDAR) data and low-cost imagery from Unmanned Aerial Systems (UAS) to estimate aboveground biomass and canopy structure of American sycamore SRWCs to address the resource intensive and spatially limited field approach of estimating aboveground biomass. The fifth chapter was devoted to studying human dimensions of the broad-based adoption of SRWCs among farmers in North Carolina, using an actor diagramming and tracing approach, literature review, participatory prototyping, and interview of stakeholders. In Conclusions (Chapter 6), I summarized all the findings from these chapters, and discussed some limitations of the study as well as future work directions.
