Dissertation Description:

My research focuses on land-use/cover change, carbon dynamics, and land use management activities in tropical forest ecosystems and coffee agroecological systems. In 2010, vegetation inventories and soil samples were collected in shade-grown coffee systems and a mixed tropical dry forest system in Guatemala to determine carbon in three pools – aboveground, belowground, and soil. A manuscript detailing the results of this research was submitted to the journal Agriculture, Ecosystems & Environment in June 2011.

Remote sensing analysis to spectrally differentiate shade-grown coffee from forests is currently underway and involves utilizing and comparing various spatial techniques to maximize classification accuracy. Such techniques include a maximum likelihood classifier, spectral mixture analysis, topographic correction, and a stratified model based on elevation. Initial classification of a Landsat TM 2010 image using spectral mixture analysis and a stratified model has yielded an accuracy of 85% (Kappa = 0.79).
