United States Land Cover Land Use Change, Albedo And Radiative Forcing: Past And Potential Climate Implications, Christopher A. Barnes
Electronic Theses and Dissertations
Land Cover Land Use (LCLU) change affects Earth surface properties including albedo that impose a radiative forcing on the climate. Recent spatially explicit satellite derived contemporary LCLU, albedo, and projected LCLU data are used to study the impact of LCLU change from 1973 to 2000, and from 2000 to 2050, on albedo and surface radiative forcing for the conterminous United States. Four research hypotheses concerned with past and potential future climate implications of LCLU change are addressed. The research described in this dissertation makes an important contribution to advancing understanding of the role of LCLU change on the climate system, …

Migration, Food And Cultural Production Across Changing Afro-Ecuadorian Geographies, Amelia J. Swinton
Honors Theses
The human geography of Ecuador is changing. Urban Afro-Ecuadorians now outnumber those living in the two rural regions that have been the ancestral homelands of the population. This physical transformation assaults Ecuador's historically racialized geography, which conflated cities, modernity and white-mestizo identity. Though Afro-Ecuadorians living in the rural north had previously been physically and figuratively located outside of the national project, Ecuador’s new constitution has sought to reverse this institutionalized exclusion. National belonging has been reframed through the concept of interculturality, which recognizes diversity and equality at the same time. I conducted two periods of fieldwork in the north-central Chota …

Tracking Bare Sand Mobilization Arising From Landscape Manipulations In The Grasslands Destabilization Experiment (Gdex) In The Nebraska Sandhills Using Imaging Spectroscopy, Benjamin Helder
The Journal of Undergraduate Research
The Grassland Destabilization Experiment (GDEX) is a landscape scale manipulative experiment initiated in 2004 in the Nebraska Sandhills to evaluate changes in surface properties following the abrupt loss of stabilizing vegetation. The GDEX features five treatments allocated among ten plots of 120 m in diameter (1.13 ha). The Aggressive Bare Sand protocol included chemical defoliation and subsequent shallow disking and raking in 2004 to devegetate the plot with periodic physical disturbance to maintain bare sand. The Long Term Disturbance (Press) protocol includes an initial chemical defoliation in May 2005 and seasonal spring reapplications, but no physical disturbance. Short Term Disturbance …

Relating Surface Backscatter Response From Trmm Precipitation Radar To Soil Moisture: Results Over A Semi-Arid Region,

Relating Surface Backscatter Response From Trmm Precipitation Radar To Soil Moisture: Results Over A Semi-Arid Region, Haroon Stephen, Sajjad Ahmad, Thomas C. Piechota, Chunling Tang
Public Policy and Leadership Faculty Research
The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σº) of the surface. σº is sensitive to surface soil moisture and vegetation conditions. Due to sparse vegetation in arid and semi-arid regions, TRMMPR σº primarily depends on the soil water content. In this study we relate TRMMPR σº measurements to soil water content (m(s)) in the Lower Colorado River Basin (LCRB). σº dependence on ms is studied for different vegetation greenness values determined through Normalized Difference Vegetation Index (NDVI). A new model of σº that couples incidence angle, m(s), and NDVI is used …

Land Surface Brightness Temperature Modeling Using Solar Insolation, Haroon Stephen, Sajjad Ahmad, Thomas C. Piechota
Public Policy and Leadership Faculty Research
Retrieval of land surface emissivity and temperature from microwave brightness temperature data is a complex problem. The diurnal variation of temperature due to the diurnal cycle of solar radiation and weather conditions makes this problem even more challenging. In this paper, we use solar radiation in modeling the temporal variation of the brightness temperature state of the surface. Solar insolation modeling is used to estimate the diurnal variation of land surface brightness temperature. Solar radiation and brightness temperature are linked through temperature of the surface which is derived based on the radiation balance equation. The temperature state model behaves consistent …

The daily media is filled with images of catastrophic events which seem increasingly frequent and violent In parallel there are a large range of scientific studies debates in the policy arena, and a growing number of international institutions focused on disaster reduction. But a paradox remains that despite advances in technology, disasters continue to increase, affecting many individuals in rich as well as poor countries.

Assessing the potential for threatened species to persist and spread within fragmented landscapes requires the identification of core areas that can sustain resident populations and dispersal corridors that can link these core areas with isolated patches of remnant habitat. We developed a set of GIS tools, simulation methods, and network analysis procedures to assess potential landscape connectivity for the Delmarva fox squirrel (DFS; Sciurus niger cinereus), an endangered species inhabiting forested areas on the Delmarva Peninsula, USA. Information on the DFS’s life history and dispersal characteristics, together with data on the composition and configuration of land cover on the peninsula, …

Extractive Reserves, David S. Salisbury
Geography and the Environment Faculty Publications
Extractive reserves are territories dedicated to environmental protection and the sustainable use of nature resources by traditional populations. Reserves follow a traditional land tenure model based on individual family and communal property rights to common areas, such as forest trails used to extract or harvest nontimber forest products. Although the extractive reserve concept originates in the tropical forests of the Brazilian Amazon, reserves have also been created in aquatic, floodplain, and savanna landscapes throughout Brazil. There are now 50 extractive reserves covering more than 10 million hectares, an area larger than Portugal, and more continue to be created. Despite their …

Saving Saba Bank: Policy Implications Of Biodiversity Studies, Paul C. Hoetjes, Kent E. Carpenter

Saba Bank has always been an area of special importance to the neighboring island of Saba in the Netherlands Antilles. Sabans traditionally fished on the Bank as far back as 1907, but increasing foreign fishing pressures on the Bank in the 1970s and 1980s forced many Saban fishermen out. Concerns were compounded by the suspicion that shipping was also damaging the benthic habitat of the bank. Fishery legislation, enacted in 1996, brought an end to unlicensed fishing and established Coast Guard enforcement on the Bank, but also led to protests from neighboring countries that previously fished on the Bank.Research was …

Climatic And Spatial Variations Of Mount Rainier's Glaciers For The Last 12,000 Years, Michael Leslie Hekkers
Dissertations and Theses
Regional paleoclimatic proxies and current local climate variables and were analyzed to reconstruct paleoglaciers in an effort to assess glacier change On Mount Rainier. Despite the dry and generally warm conditions (sea surface temperatures (SST) -0.15°C to +1.8°C relative to current temperatures), the previously documented McNeeley II advance (10,900 - 9,950 cal yr B.P.) was likely produced by air temperature fluctuations. The average SST record and the terrestrial climate proxies show cooling temperatures with continued dryness between McNeeley II and the Burroughs Mountain advance (3,442 - 2,153 cal yr B.P.). The paleoclimate during the Burroughs Mountain advance was both cool …

Geography and Environmental Studies Faculty Publications
The tourism sector is one of the largest and fastest growing global industries and is a significant contributor to national and local economies around the world. The interface between climate and tourism is multifaceted and complex, as climate represents both a vital resource to be exploited and an important limiting factor that poses risks to be managed by the tourism industry and tourists alike. All tourism destinations and operators are climate-sensitive to a degree and climate is a key influence on travel planning and the travel experience. This chapter provides a synopsis of the capacities and needs for climate services …
