Us County-Level Agricultural Crop Production Typology, Courtney R. Hammond Wagner, Meredith T. Niles, Eric D. Roy

Rubenstein School of Environment and Natural Resources Faculty Publications
Objectives: Crop production is an important variable in social, economic and environmental analyses. There is an abundance of crop data available for the United States, but we lack a typology of county-level crop production that accounts for production similarities in counties across the country. We fill this gap with a county-level classification of crop production with ten mutually exclusive categories across the contiguous United States. Data description: To create the typology we ran a cluster analysis on acreage data for 21 key crops from the United States Department of Agriculture's 2012 Agricultural Census. Prior to clustering, we estimated undisclosed county …

Methods For The Spatial Modeling Of Forest Carbon In The Northern Forest, Alison Adams
Methods For The Spatial Modeling Of Forest Carbon In The Northern Forest, Alison Adams
Graduate College Dissertations and Theses
The ability to accurately assess forest carbon storage is critical to understanding global carbon cycles and the effects of changes in land cover on ecological processes. However, existing methods for calculating carbon storage do not explicitly account for differences in carbon stored by different species of trees. Those methods that do reflect some of this variability, such as remotely-sensing canopy structure to estimate biomass, can be resource-intensive and difficult to reproduce over past or future time steps in order to assess change. I examined the accuracy of several carbon mapping approaches to understand how specificity of forest type classification (for …
