Interannual Variability Of Photosynthesis Across Africa And Its Attribution, Christopher A. Williams, Niall P. Hanan, Ian Baker, G. James Collatz, Joseph Berry, A. Scott Denning

Geography

Africa is thought to be a large source of interannual variability in the global carbon cycle, only vaguely attributed to climate fluctuations. This study uses a biophysical model, Simple Biosphere, to examine in detail what specific factors, physiological (acute stress from low soil water, temperature, or low humidity) and biophysical (low vegetation radiation use), are responsible for spatiotemporal patterns of photosynthesis across the African continent during the period 1982-2003. Acute soil water stress emerges as the primary factor driving interannual variability of photosynthesis for most of Africa. Southern savannas and woodlands are a particular hot spot of interannual variability in …

Integrating Landscapes That Have Experienced Rural Depopulation And Ecological Homogenization Into Tropical Conservation Planning, Aerin L. Jacob, Ismael Vaccaro, Raja Sengupta, Joel N. Hartter, Colin A. Chapman

Geography

If current trends of declining fertility rates and increasing abandonment of rural land as a result of urbanization continue, this will signal a globally significant transformation with important consequences for policy makers interested in conservation planning. This transformation is presently evident in a number of countries and projections suggest it may occur in the future in many developing countries. We use rates of population growth and urbanization to project population trends in rural areas for 25 example countries. Our projections indicate a general decline in population density that has either occurred already (e.g., Mexico) or may occur in the future …

Contention And Ambiguity: Mining And The Possibilities Of Development, Anthony J. Bebbington, Leonith Hinojosa, Denise Bebbington, Maria Luisa Burneo, Ximena Warnaars

Geography

The last decade and a half has witnessed a dramatic growth in mining activity in many developing countries. This article reviews these recent trends and describes the debates and conflicts they have triggered. The authors review evidence regarding debates on the resource curse and the possibility of an extraction-led pathway to development. They then describe the different types of resistance and social mobilization that have greeted mineral expansion at a range of geographical scales, and consider how far these protests have changed the relationships between mining and political economic change. The conclusions address how far such protests might contribute to …

Social Movements And The Dynamics Of Rural Territorial Development In Latin America, Anthony J. Bebbington, Ricardo Abramovay, Manuel Chiriboga

Geography

This special section brings together 4 of the 12 studies conducted within a research program analyzing the relationships among social mobilization, governance, and rural development in contemporary Latin America. The introduction gives an overview of the contemporary significance of social movements for rural development dynamics in the region, and of the principal insights of the section papers and the broader research program of which they were a part. This significance varies as an effect of two distinct and uneven geographies: the geography of social movements themselves and the geography of the rural political economy. The effects that movements have on …

Simulation Modeling Of Karst Aquifer Conduit Evolution And Relations To Climate, John D. Broome

Masters Theses & Specialist Projects

ABSTRACT Karst regions of the world that receive relatively similar amounts of precipitation display a wide variety of landscapes. It has been suggested (Groves and Meiman, 2005) that climates exhibiting larger discrete storm events have more dissolving power and consequently higher rates of conduit growth than climates with more uniform precipitation distributions. To study this concept, a computer program “Cave Growth” was developed that modeled the growth of a cross-section of a cave passage under dynamic flow and chemical conditions. A series of 46 simulation datasets were created to represent different climatic conditions. These simulations had the same total annual …

Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker

Masters Theses & Specialist Projects

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be …

Finding A "Disappearing" Nontimber Forest Resource: Using Grounded Visualization To Explore Urbanization Impacts On Sweetgrass Basketmaking In Greater Mt. Pleasant, South Carolina, Patrick T. Hurley, Angela C. Halfacre, Norm S. Levine, Marianne K. Burke

Environment and Sustainability Faculty Publications

Despite growing interest in urbanization and its social and ecological impacts on formerly rural areas, empirical research remains limited. Extant studies largely focus either on issues of social exclusion and enclosure or ecological change. This article uses the case of sweetgrass basketmaking in Mt. Pleasant, South Carolina, to explore the implications of urbanization, including gentrification, for the distribution and accessibility of sweetgrass, an economically important nontimber forest product (NTFP) for historically African American communities, in this rapidly growing area. We explore the usefulness of grounded visualization for research efforts that are examining the existence of "fringe ecologies" associated with NTFP. …

Background And Study Concerning Water Wave Effects On Airborne Imagery, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

This paper describes ongoing research and initial results regarding collection of airborne imagery for detection of submerged features in optically shallow water types. The approach is to utilize land surface, water surface and submerged or in-situ line targets of various types during the airborne flights or fixed platforms. The imagery collected by the airborne sensing systems is processed in concept to correct for the presence of the water surface wave effects and water column effects. The correction approach is based upon calculation of a residual image between either (a) the observed submerged target image and the non-submerged image or (2) …

“Left In The Forest And Forgotten” Land Policy And The Plight Of The Benet, Anne Dirkse

Independent Study Project (ISP) Collection

In carrying out my independent study project on the issue of the Benet being displaced by the creation of Mount Elgon National Park, I had three main objectives in my mind. My first objective was to investigate and gain a balanced perspective of the effects of the Benet’s most recent eviction from Mount Elgon National Park. Secondly, I wished to analyze the government’s role as a duty bearer in compensating and resettling the Benet for their land. Lastly, I wished to explore the Benet Community’s options for redress within the legal system.

The methods I utilized included a literature review, …

La Mondialisation Et Les Croyants: Des Effets De La Mondialisation Sur Les Communautés Chrétiennes = Globalization And Believers: Globalization’S Effects On Christian Communities, Carrie Lee Tallichet

Independent Study Project (ISP) Collection

This research aimed to explore the different manifestations of globalization’s impact on Catholic and Protestant student movements in Toulouse, France. To accomplish this investigation, the researcher sought the opinions of students who participate regularly in religious groups regarding the cultural diversity of their group and their concept of a global Christian community. Based on information gathered in interviews, the researcher concluded, though not definitively, that Catholic and Protestant student groups both experience the effects of globalization, but each in a manner in relation with their faith’s organizational structure: Catholic students felt close ties with other Catholic groups worldwide despite the …

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan

Earth, Environmental, and Atmospheric Sciences Faculty Publications

A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …

Defining A Fire Year For Reporting And Analysis Of Global Interannual Fire Variablility, Luigi Boschetti, David P. Roy

GSCE Faculty Publications

The interannual variability of fire activity has been studied without an explicit investigation of a suitable starting month for yearly calculations. Sensitivity analysis of 37 months of global MODIS active fire detections indicates that a 1-month change in the start of the fire year definition can lead, in the worst case, to a difference of over 6% and over 45% in global and subcontinental scale annual fire totals, respectively. Optimal starting months for analyses of global and subcontinental fire interannual variability are described. The research indicates that a fire year starting in March provides an optimal definition for annual global …

Patterns And Consequences Of Segregation: An Analysis Of Ethnic Residential Patterns At Two Geographic Scales, Kenneth N. French

Department of Geography: Dissertations, Theses, and Student Research

American cities are diverse, with people from various ethnic backgrounds calling the city their home. Instead of having numerous culturally mixed neighborhoods, many residential areas are segregated by ethnicity. Also, social opportunities, such as access to jobs and quality education, are not evenly distributed in urban space. In short, separate living spaces may not mean equal living spaces. What are the impacts of living in White or African American or Hispanic or Asian neighborhoods? Thus, it is worthwhile to investigate the patterns and consequences of ethnic residential segregation. This dissertation employs several cartographic, geographic information system (GIS), and statistical techniques …

Water And Mining Conflicts In Peru, Anthony J. Bebbington, Mark Williams

Geography

Impacts on water quality and quantity are among the most contentious aspects of mining projects. Companies insist that the use of modern technologies will ensure environmentally friendly mining practices. However, evidence of the negative environmental impacts of past mining activity causes local and downstream populations to worry that new mining activities will adversely affect their water supply. We report on one mine site in Peru where water has become a: particularly conflictive issue. We then provide a detailed proposal for a monitoring plan to recover trust among stakeholders. A welldesigned and executed monitoring plan for water quantity and quality is …
