Anthropology Faculty Publications
Architectural reconstructions are the centerpieces of ancient landscape visualization. When present, vegetation is relegated to the background, resulting in underutilized plant data—an integral data source for archaeological interpretation—thus limiting the capacity to take advantage of 3D visualization for studying ancient socio-environmental dynamics. Our long-term objective is to develop methods of 3D landscape visualization that have value for examining changes in land use and settlement patterns. To begin to work toward this objective, we have (1) identified 3D tools and techniques for vegetation modeling and landscape visualization, (2) evaluated the pros and cons of these tools, (3) investigated biological ...
The New Normal? Climate Variability And Ecoviolence In Sub-Saharan Africa, 2016 University of New Orleans
The New Normal? Climate Variability And Ecoviolence In Sub-Saharan Africa, Alfonso Sanchez
University of New Orleans Theses and Dissertations
Climate change presents a wide range of concerns that can jeopardize international security. Among those concerns are neo-Malthusian worries of diminishing natural resources. Predictive models suggest that rainfall and temperature anomalies have the potential to reduce water basins, crop production, increase land degradation among other perils that threaten human security. This concern is particularly true in sub-Saharan Africa given the region’s strong dependence on rain-fed agriculture. Despite strong claims from various world leaders and scientists of a direct climate-conflict nexus, little empirical evidence has been devoted to find a systematic causal pathway of this kind. What is more, the ...
Reanalysis Data Underestimate Significant Changes In Growing Season Weather In Kazakhstan, 2016 Oklahoma State University
Reanalysis Data Underestimate Significant Changes In Growing Season Weather In Kazakhstan, C. K. Wright, K. M. De Beurs, Z. K. Akhmadiyeva, P. Y. Groisman, G. M. Henebry
We present time series analyses of recently compiled climate station data which allowed us to assess contemporary trends in growing season weather across Kazakhstan as drivers of a significant decline in growing season normalized difference vegetation index (NDVI) recently observed by satellite remote sensing across much of Central Asia. We used a robust nonparametric time series analysis method, the seasonal Kendall trend test to analyze georeferenced time series of accumulated growing season precipitation (APPT) and accumulated growing degree-days (AGDD). Over the period 2000–2006 we found geographically extensive, statistically significant (p < 0.05) decreasing trends in APPT and increasing trends in AGDD. The temperature trends were especially apparent during the warm season and coincided with precipitation decreases in northwest Kazakhstan, indicating that pervasive drought conditions and higher temperature excursions were the likely drivers of NDVI declines observed in Kazakhstan over the same period. We also compared the APPT and AGDD trends at individual stations with results from trend analysis of gridded monthly precipitation data from the Global Precipitation Climatology Centre (GPCC) Full Data Reanalysis v4 and gridded daily near surface air temperature from the National Centers for Climate Prediction Reanalysis v2 (NCEP R2). We found substantial deviation between the station and the reanalysis trends, suggesting that GPCC and NCEP data substantially underestimate the geographic extent of recent drought in Kazakhstan. Although gridded climate products offer many advantages in ease of use and complete coverage, our findings for Kazakhstan should serve as a caveat against uncritical use of GPCC and NCEP reanalysis data and demonstrate the importance of compiling and standardizing daily climate data from data-sparse regions like Central Asia.
Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, 2016 South Dakota State University
Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, A. Midekisa, G. Senay, G. M. Henebry, P. Semuniguse, M. C. Wimberly
Malaria is one of the leading public health problems in most of sub-Saharan Africa, particularly in Ethiopia. Almost all demographic groups are at risk of malaria because of seasonal and unstable transmission of the disease. Therefore, there is a need to develop malaria early-warning systems to enhance public health decision making for control and prevention of malaria epidemics. Data from orbiting earth-observing sensors can monitor environmental risk factors that trigger malaria epidemics. Remotely sensed environmental indicators were used to examine the influences of climatic and environmental variability on temporal patterns of malaria cases in the Amhara region of Ethiopia ...
Assessing The Impacts Of Climate And Land Use And Land Cover Change On The Freshwater Availability In The Brahmaputra River Basin, 2016 South Dakota State University
Assessing The Impacts Of Climate And Land Use And Land Cover Change On The Freshwater Availability In The Brahmaputra River Basin, M. S. Pervez, G. M. Henebry
Study Region: Brahmaputra River basin in South Asia.
Study Focus: The Soil and Water Assessment Tool was used to evaluate sensitivities and patterns in freshwater availability due to projected climate and land use changes in the Brahmaputra basin. The daily observed discharge at Bahadurabad station in Bangladesh was used to calibrate and validate the model and analyze uncertainties with a sequential uncertainty fitting algorithm. The sensitivities and impacts of projected climate and land use changes on basin hydrological components were simulated for the A1B and A2 scenarios and analyzed relative to a baseline scenario of 1988–2004.
New hydrological insights ...

Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, 2016 The University of Western Ontario
Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras
Electronic Thesis and Dissertation Repository
The repeated occurrence of Lake Erie’s harmful algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in phosphorus loads relative to 2008. To provide scientific evidence to guide managers toward achieving their management objective, we used the International Standard of Organization (ISO) 31010 Bowtie Risk Analysis Tool to analyze the performance of the phosphorus management system. The effectiveness of agricultural best management practices (BMPs) and their adoption were combined into a Bayesian belief network model to ...
Institutionalizing Environmental Justice: Race, Place, And The National Environmental Policy Act, 2016 The Graduate Center, City University of New York
Institutionalizing Environmental Justice: Race, Place, And The National Environmental Policy Act, Keith K. Miyake
All Graduate Works by Year: Dissertations, Theses, and Capstone Projects
In this dissertation, I examine ways that the US National Environmental Policy Act of 1969 (NEPA) and its primary enforcement mechanism, the Environmental Impact Assessment (EIA) process, have reshaped the state as a site for racial and environmental conflict by institutionalizing a particular form of environmental justice within governmental decision making processes. Combining archival methods and legal analysis, I develop three case studies involving community struggles over the social production of space that each engage the EIA process to different effect. The case studies were selected based on what they reveal about the ways that the environmental justice framework intersects ...
