My research focuses on the interactions between dynamic human and natural systems. I use remote sensing and spatio-temporally explicit models to study these processes at spatial and temporal scales typically prohibitive for studies based on ground observations only. Currently, we are developing methods to better quantify the spatial arrangement and temporal dynamics of natural systems using time-series of remote sensing data and examining the interactions between socio-economic and biophysical systems that lead to these dynamics.
I examine the interactions between human activities and natural systems at landscape to regional-level scales with particular interest in studying the impacts of human activities on the spatio-temporal dynamics of natural systems. I use remotely sensed data and spatially explicit models to better understand the interactions between human and natural systems.
We have developed a state‐wide program to integrate plot‐level bioenergy research with state‐wide remote sensing analyses through newly available airborne hyperspectral sensor capabilities, the Hawkeye Hyperspectral Imager. Specifically, we are examining the application of a suite of airborne hyperspectral sensors capable of taking detailed measurements of the reflected light from the earth’s surface at a relatively fine spatial resolution (ca. 1m). These capabilities will significantly extend our ability to discern vegetation communities (e.g., invasive species and complex patterns of plant communities in floodplains), empirically measure canopy and topsoil characteristics (such as leaf area, nitrogen and water content), and model the interactions of light with canopies. Hyperspectral modeling relationships and data fusion are used to develop scaling relationships to parameterize and validate landscape to regional biophysical remotely sensed products and extend our knowledge of human‐ environment interactions.
Modeling Human/Environment Interactions
Remote sensing data provide decades of detailed, spatially-explicit information on human impacts. Using declassified spy satellite photography from the 1960’s and civilian satellite imagery from 1970 - 1990’s, for example, we examined human impacts on giant panda habitat over several decades. These data allowed us to estimate not only the quantity of changes, but also to examine the potential impacts from the timing and spatial arrangement of the changes (Linderman et al. 2005a). Measures of habitat quality and landscape indices were used to asses the spatial implications of land-cover changes. To examine the interactions between households and the landscape, I developed a model to study the indirect impacts of the removal of forest cover on understory bamboo dynamics. Bamboo species typically undergo a regular mass seeding and die-off event before returning to pre-die-off quantities and distribution. We found that the timing and spatial distribution of human impacts may have a considerable impact on this natural dynamic of bamboo species through the removal of forest cover and, consequently, species that rely on bamboo such as the giant panda (Linderman et al. 2006).
In addition, I am also examining broader-scale spatio-temporal variability such as the interannual variability of vegetation productivity across sub-Saharan Africa. Using time series of MODIS 1-km resolution data and newly developed indices of interannual variability, we mapped the changes in timing and magnitude of vegetation activity each year between 2000 and 2004 across Africa (Linderman et al. 2005b). We are examining the regional to global factors influencing these changes such as climate, land use, vegetation types, and abiotic factors to determine the pre-disposing factors of interannual variability and the potential significance for local to global-scale processes (Serneels et al. 2007). As shown by Rowhani et al. (2008), these relatively high-frequency dynamics have significant implications for natural systems. We are currently extending this work to examine land-use impacts on interannual variability in prairie and agricultural systems in Iowa and the influence of variability on society such as through health and food security.
