Publications and Research

Improved irrigation use efficiency is an important tool for intensifying and diversifying agriculture in Nepal, resulting in higher economic yield from irrigated farmlands with a minimum input of water. Research was conducted to evaluate the effect of irrigation method (furrow vs. drip) on the productivity of nutritious fodder species during off-monsoon dry periods in different elevation zones of central Nepal. A split-block factorial design was used. The factors considered were treatment location, fodder crop, and irrigation method. Commonly used local agronomical practices were followed in all respects except irrigation method. Results revealed that location effect was significant (p < 0.01) with highest fodder productivity seen for the middle elevation site, Syangja. Species effects were also significant, with teosinte (Euchlaena mexicana) having higher yield than cowpea (Vigna unguiculata). Irrigation method impacted green biomass yield (higher with furrow irrigation) but both methods yielded similar dry biomass, while water use was 73% less under drip irrigation. Our findings indicated that the controlled application of water through drip irrigation is able to produce acceptable yields of nutritionally dense fodder species during dry seasons, leading to more effective utilization and resource conservation of available land, fertilizer and water. Higher productivity of these nutritional fodders resulted in higher milk productivity for livestock smallholders. The ability to grow fodder crops year-round in lowland and hill regions of Nepal with limited water storages using low-cost, water-efficient drip irrigation may greatly increase livestock productivity and, hence, the economic security of smallholder farmers.

Documenting Spatial And Temporal Information For Heritage Preservation: A Case Study Of Sri Lanka, Chiranthi Wijesundara, Shigeo Sugimoto, Bhuva Narayan

Proceedings from the Document Academy

Cultural Heritage Properties (CHPs) around the world have been altered or destroyed due to various unforeseen factors, both natural and human-made. Consequently, as a preparedness approach around such disasters, documenting the CHPs are crucial to any efforts to repair, rebuild or relocate them. With advancements in digital technologies, integrating them into our documentation to improve heritage preservation has become a common approach. Here the main concern is on Spatial and Temporal (ST) information and the paper proposes that with recent developments in the field of Geospatial technologies, heritage preservation can be enhanced and improved by documenting ST information parallel to …

Computationally Inexpensive Landsat 8 Operational Land Imager (Oli) Pansharpening, Hankui Zhang, David P. Roy

GSCE Faculty Publications

Pansharpening algorithms fuse higher spatial resolution panchromatic with lower spatial resolution multispectral imagery to create higher spatial resolution multispectral images. The free-availability and systematic global acquisition of Landsat 8 data indicate an expected need for global coverage and so computationally efficient Landsat 8 pansharpening. This study adapts and evaluates the established, and relatively computationally inexpensive, Brovey and context adaptive Gram Schmidt component substitution (CS) pansharpening methods for application to the Landsat 8 15 m panchromatic and 30 m red, green, blue, and near-infrared bands. The intensity images used by these CS pansharpening methods are derived as a weighted linear combination …

Assessing The Impact Of A Supermarket Shuttle Model On Supermarket Access Within Cabell County, West Virginia, Doug Wiley

Theses, Dissertations and Capstones

Will the implementation of a grocery shuttle impact supermarket access for residents of Cabell County, West Virginia? The concentration of supermarkets in the City of Huntington has led to a service gap in the outlying census block groups of the study area. Supermarket access is concentrated in the City of Huntington and may provide a positive outcome for families living within the city. The study assesses the impact of the implementation of a supermarket shuttle on supermarket access within the study area, through spatial analysis of supermarkets, transportation networks, and census block groups. The transportation network data and census block …

Reaching The Water's Edge: Assessing Riverfront Accessibility In The Quad Cities Area, Lorraine Stamberger

Geography: Student Scholarship & Creative Works

In river towns across the United States, a slow transformation is taking place as aging and abandoned industrial infrastructure is being replaced by new riverfront uses. Consequently, the urban American riverfront has become a battleground, with municipalities, developers, and large corporations fighting over this contested land. Although riverfronts offer a wealth of benefits for the public such as therapeutic river views and abundant recreational opportunities, studies have shown that public interests and access are often overlooked in the waterfront development process. The purpose of this research is to understand the level of access people in the Quad Cities community have …

Crafted Places: The Use Of Place In Wisconsin Craft Beer Marketing, Joseph A. Quintana

Electronic Theses and Dissertations

This research examines place-related themes used in craft beer marketing initiatives in Wisconsin. "Place" describes the emotions and perceptions individuals hold in certain locations. Place theory, despite being universally experienced, is relatively understudied. Furthermore, this project is grounded in the recent neolocal movement - a movement towards local culture, and away from national homogenous culture. Broadly, this paper aims to understand the perceptual linkages between people and "their" place. In order to understand place and neolocal themes within these linkages, this project analyzes how individual beer names, beer-label imagery, and beer-related advertisements use familiar places to link products with a …

Access To Recreational Open Space In Patterson, Ca: A Geospatial Analysis Utilizing Geographic Information Systems, Leanne S. Lynch

Projects

Many cities throughout California have experienced land use shifts from prime agricultural land to developed industrial and residential areas without considering access to recreational open space. Access to recreation through open space or parks is beneficial for the health and well-being of the community while providing aesthetic value and potential preservation of local ecosystems. Since 2002 the City of Patterson, located in California’s Central Valley, has rezoned over 800 acres of agricultural land for urban and industrial use while developers reserved recreational open space (parkland) at locations inconvenient to existing neighborhoods. Although several acres of parkland have been added to …
