Master of Science / Department of Architecture / R. Todd Gabbard / Almost forty percent of the global energy use and one-third of the global greenhouse gas emission comes from the building industry. Thus, this sector has the largest potential for delivering long term substantial greenhouse gas reduction. (UNEP, 2009)This dissertation starts with the energy auditing of an architectural firm to calculate the amount of energy used. It then expands into addressing the issue on a greater perspective. The whole agenda of the thesis was to develop a strategy to include the building industry in global carbon market. This thesis was performed in collaboration with nationally recognized, medium-sized mid-western architecture firm. A yearlong internship was completed under this firm, and collaborative research was carried out. To reduce the carbon dioxide emission, it is crucial to be able to measure it. This thesis aims at creating basic guidelines for architecture firms to mitigate its carbon footprint. It also examines the possibilities of carbon footprint mitigation on a bigger scale by proposing a system that would encourage architectural and engineering firms to design and produce more energy efficient buildings. The proposed system deals with calculation and incorporation of creative handprint of an architectural firm and uses the system to rebate its carbon footprint and convert the surplus handprint to a credit in the carbon market. The argument made here is that this scheme is driven by incentives and encourages more architecture and engineering firms to design sustainable buildings. The final proposal links the entire building industry to the carbon market. The proposal made is that a positive handprint of architecture and engineering firms can be converted to carbon credits and traded in the carbon markets.

Master of Arts / Department of Geography / John Harrington Jr / Agriculture is vital to the character of Kansas. It is threaded through the social, economic, and environmental systems that operate in Kansas and bring each system into interaction with one another. Loss of agriculture would mean drastic changes to traditional Kansas way of life due to the three pronged nature of agriculture in Kansas. Continuation of agricultural activity then is of great importance. Globalization, climate change, and environmental change pose threats to agricultural futures. This study is a meta-analysis of current literature in an attempt to assess the current state of sustainable agriculture in the state of Kansas. An emphasis was placed on climate as a driver of change and ways in which agricultural producers in Kansas may begin implementing sustainable adaptations. Barriers to implementing sustainable agricultural adaptations were also identified in the literature. Broadly speaking analysis focused on barriers created through policy and barriers created through gaps in knowledge and weak or missing connections, or cognitive barriers. Information gathered in the course of the literature analysis was used to generate two potential future agricultural scenarios for Kansas. Scenarios can be used to aid policy makers in assessing potential impacts of environmental change and interactions between different systems and scales. Two separate scenarios, Business-As-Usual and Sustainable-Adaptive, were developed with distinct characteristics. The Business-As-Usual scenario represents a future that is framed similar to the current situation. Changes built into the scenario stem from the projected changes to climate. The remainder of the narrative describes a future that has pursued developmental pathways driven by current policy and market forces. In contrast, the Sustainable-Adaptive scenario represents a Policy Reform scenario in which there is strong guidance through policy towards a developmental pathway that focuses on sustainable agricultural methods. This scenario describes a future in which environmental degradation is slowed or even reversed. Continued future work may focus on the role of water availability, community level impacts of sustainable adaptations, and the integration of stakeholder values as another layer of complexity in future scenarios.

Master of Science / Department of Horticulture, Forestry, and Recreational Resources / Rhonda Janke / With the increasing popularity of urban farming, more people are seeking resources to start their own farming/growing production in urban environments. Traditionally, county Extension educators are a key resource for beginning farmers and growers. However, urban Extension offices are often overlooked as resources in the urban farming planning process. The objectives of this study are 1) identify information urban farmers currently have, information they need, and their preferred delivery methods 2) look at the resources and information that are offered by local Extension educators in the KC metro area and 3) analyze how these two groups are communicating and what could improve to meet farmers‟ needs. This project evaluates current interaction between urban farmers and Extension educators in the Kansas City area through a two-pronged approach: a written mail-out questionnaire for urban farmers and growers in the Kansas City metropolitan area and through in-person one-on-one interviews with Extension educators that emphasize topic areas related to urban agriculture in the KC area. One hundred and nineteen farmers/growers were surveyed, and a 54.6% response rate was achieved. The majority of farmers had small, diversified farms and were relatively new to farming. Respondents were primarily older, white men that had higher education. Independently-driven sources (such as self-research, other farmers, and friends/family) were most commonly used sources among farmers. Overall, respondents ranked Extension highly in terms of information quantity, quality and as their "go to" source. Extension educators from Kansas State University, University of Missouri, and Lincoln University were interviewed one-on-one using scripted interview questions to determine topics and medias of information that are currently being offered. Production and processing information is offered the most by educators followed by distribution, equipment, and marketing information. Financial information was the least offered information topic. Extension educators use a wide variety of methods to distribute information. Most Extension educators are aware of benefits and barriers relating to urban agriculture in the KC metro area. Extension educators are addressing urban agriculture in varying degrees and the level of involvement corresponds to the Extension institution.

Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / John W. Keller / Regions are an intricate network of communities, geographies and economies that together impact the long-term growth and stability of one other. Cooperation between municipalities within the same region is vital in order to achieve sustained growth, both economically and in the built environment. The research question states: What is the value of regional planning bodies in ensuring effective communication and collaboration among region-wide governmental and non-governmental agencies? This research report includes a detailed history of the role and significance of regional planning bodies in the United States, as well as a case study involving the regional planning body in Houston, Texas and the Gulf Coast Region. The Houston-Galveston Area Council is the lead participant in a 25-member coordinating committee working together to complete a regional sustainability plan under the federally funded Sustainable Communities Regional Planning Grant Program. The interviews included in this report give conclusions and recommendations to the success of the region working together in terms of communication and collaboration. The challenge of establishing effective collaboration among a variety of agencies in the Gulf Coast Region is proving to be difficult and slow moving, however, there are signs of improvement as the three-year grant program moves forward. The conclusions from the literature review and case study show that regions with an unbiased planning body benefit both from the communication and social capital gained by working together on a shared goal.

Master of Science / Department of Civil Engineering / Steven K. Starrett / Current aquaponic technology ranges from backyard hobbyist to technologically advanced commercial production. A single source for protein (fish) and nutrients/vitamins (vegetables), development of a technologically simplified commercial-scale system is a realistic solution for many impoverished nations. This study develops a simplified aquaponic facility to be implemented in rural northern Uganda. Research objectives were to: (1) identify simplified commercial-scale system design components, (2) establish a water quality baseline, (3) identify plant/tilapia production ratios, (4) identify construction materials available in northern Uganda, (5) integrate culturally familiar elements, (6) complete preliminary facility design, and (7) calculate facility water balance. The study established that a viable simplified design achieves: (1) water circulation with weir gravity flow and one return pump, (2) tank cleaning with strategically sloped floors and manual waste siphoning, and (3) breeding control with raised bottom fishnets. Submerged aeration is critical to optimal fish growth, and cannot be eliminated despite surface aeration’s low energy appeal. Baseline water quality parameter values of DO > 3 mg/L, pH > 5.5, and TAN > 3 mg/L (2 mg/L average) were established for the pilot study configuration and hydraulic retention time (HRT). A plant/tilapia ratio of 2.5 ft[superscript]2/lb was identified for the proposed facility’s design. The simplified design was assessed compatible with concrete block construction local to northern Uganda. Incorporating the following culturally familiar elements will facilitate technology adoption: utilize native fish (tilapia) and vegetable crops identified in community markets, replace commercially produced plant tank raft components with woven matting from locally available natural materials, and identify the unfamiliar proposed tank design with newly adopted raceway culture techniques at a well-known Ugandan national fishery institute. A proposed facility preliminary design represents local materials, identified plant/tilapia ratio, minimum HRT, and simplified design components for tilapia densities ranging from 12 to 3 gal/lb. With the facility supplied by both rainwater and groundwater, corresponding water balances for 12 to 3 gal/lb densities ranged from a 9,735 gal/yr well supply demand to a 10,984 gal/yr rainwater surplus.

Master of Science / Department of Landscape Architecture and Regional & Community Planning / Huston Gibson / Communities are currently faced with the issue of integrating sustainable practices into citizen lifestyles, a problem that can be addressed through behavior changes strategies. Higher education institutions can provide a testing ground for different behavior change strategies, specifically the Fogg Behavior Model (FBM) and its application to the social structures that are important in community-based social marketing (CBSM). This research proposes to examine FBM among Kansas State University faculty and staff as a viable CBSM approach for sustainable behavior change. A targeted behavior and trigger for the targeted behavior were selected. The trigger was implemented among select university departments with both pre- and post-experiment surveys distributed to assess trigger effectiveness and limiting factors to ability and motivation. The research showed an increase to the targeted behavior due to trigger implementation and described ability and motivation limiting factors within those select departments. With further investigation into these limiting factors and a widespread trigger effectiveness study, FBM could serve as an effective model that addresses social behavior change within a CBSM framework. FBM’s potential success in a university setting bodes well for its success in communities and a community-based social marketing approach to create sustainable behavior change.

Doctor of Philosophy / Department of Hospitality Management and Dietetics / Carol W. Shanklin / This study used two operational research components to explore strategies to decrease waste in university dining facilities. Component one assessed students’ beliefs and behaviors toward food waste in a selected dining center. The relationships between students’ food waste behavior, sustainability beliefs, and demographics were evaluated with the use of a self-administered survey and continual food waste monitoring. This study also assessed whether simple prompt-type message interventions had an impact or if the addition of more personally relevant feedback-based data elicited a greater change in consumer beliefs and behaviors On average, more than 57 grams of edible food was left on each tray. Food waste behaviors were not influenced by demographic factors. Individuals with higher levels of food waste beliefs also disposed of less edible food items. The simple prompt-type messages stimulated a 15% reduction in food waste. The addition of more personalized feedback-based messages did not stimulate a change above that of the prompt message. These findings indicate that simply making university students aware of the topic of food waste may be useful in improving their behaviors. Component two evaluated the operational feasibility of implementing tray free dining at Kansas State University Dining Services. Telephone interviews with managers of university dining facilities involved in tray free dining were conducted to identify best practices. Focus groups of students were used with a written survey to gain insight into their perceptions of tray free dining. Benefits included: decreased waste, reduced chemical, resource, and food costs, and improved student satisfaction. Managers identified complaints and dining room cleanliness as negative outcomes. Student involvement, education, and communication were strongly recommended by both managers and students. This research supports the recommendation to consider the implementation of tray free dining at Van Zile. Decreased costs, improved satisfaction, and positive public perception are likely positive outcomes.

Doctor of Philosophy / Department of Hospitality Management and Dietetics / Elizabeth Barrett / Water is essential for many aspects of daily life including restaurant operations and is necessary for generation and service of properly produced, safe food. However, water is becoming more scarce and expensive due to climate change, infrastructure needs, governmental budget constraints, and shifting water sources. The purpose of this study was to develop benchmarks for water usage and costs for casual dining restaurants (CDRs) in Kansas and identify demographics that may impact water usage and costs. The population for the study was the 952 CDRs in Kansas. Stratified random sampling selected 60 restaurants from five Kansas demographic regions. Data were collected from the local municipal water utilities, Kansas Department of Revenue, Google’s Place Page, and through telephone or on-site interviews with a manager. Results for 221 of 300 (74%) CDRs that responded indicated that on average 1,766 gallons of water were used each day per restaurant, 12.79 per gallons per day for each seat, 68 gallons per employee, and 0.73 gallons per interior square foot. These results were as much as 69% lower than those from a 2000 study conducted by Dziegielewski et al. Significant demographics that impacted water consumption were season of year, population (F= 9.763, p≤.001), menu (F= 2.921, p≤.035), type of ownership (F= 56.565, p≤.000), water source (F= 10.751, p≤.032), irrigation (F= 46.514, p≤.001) and days open (F= 6.085, p≤.000). A stepwise linear regression model (F= 33.676, p≤.000) found ownership (β= -.329, p ≤ 0.000), irrigation (β= -.290, p ≤ 0.000), and population (β= -.176, p ≤ 0.003) impacted water consumption. For water costs, CDRs paid an average of $6.54 per 1,000 gallons of water consumed and had mean annual expenses of $5,026 on revenues of $2,554,254 which was the equivalent of a water cost percent of 0.42. Demographics that impacted water costs were season of year, region (F = 3.167, p≤ 0.015), and water source (F = 4.692, p≤ 0.032). However, a stepwise linear regression model (F= 4.485, p ≤ 0.036) found only water source (β= -.152, p ≤ 0.036) was an indicator of the percentage of revenues related to cost of water. This study did identify benchmarks for water consumption and water costs that can be used in the future by restaurateurs. The primary limitations of the study were that results can only be generalized to casual dining restaurants in Kansas. Future studies can be conducted with different types of restaurants in Kansas and with CDRs in other areas.

Master of Regional and Community Planning / Department of Landscape Architecture and Regional and Community Planning / Tim Keane / The City of Manhattan, Kansas has been subject to intense flooding in the last couple of years. Areas of the city, within the Wildcat Creek Watershed, have been adversely affected. The City of Manhattan and stakeholders from various walks of life are looking for solutions to alleviate flooding within the area. This Master’s Project looks into rainwater harvesting as one of the solutions to help reduce stormwater runoff and contribute to the alleviation of flooding within the Watershed. Rainwater harvesting is increasingly being recognized as an effective way to reduce stormwater runoff. The project explores the potential benefit of using a network of rainwater harvesting elements, namely rain barrels and cisterns supplemented by rain gardens and other infiltration methods to reduce runoff in the City of Manhattan, Kansas. To assess the benefit of using rainwater harvesting in the City, a neighborhood scale site was chosen and divided into land use types. Three phases were used to assess the impact and implementation of rainwater harvesting. Phase I calculates the volume of runoff generated from each land use type and how much of that runoff can be harvested from the rooftops. The values from the neighborhood scale analysis were then extrapolated to see the impact of rainwater harvesting on a larger scale. Phase II looks at the configuration of a rainwater harvesting system for the structures in each land use type and rainwater reuse options. Finally, Phase III looks at policies, regulations and incentives that can be employed by the City of Manhattan to help encourage rainwater harvesting. This Master’s project seeks to educate the City and its residents about the benefits of rainwater harvesting as a stormwater management tool and provide steps towards potentially using rainwater harvesting as a way to reduce runoff, and help alleviate flooding in the Wildcat Creek Watershed.

Master of Science / Department of Agricultural Economics / Vincent R. Amanor-Boadu / This study focuses on determining what key differences predispose a consumer to regularly purchase and be willing to pay a premium for sustainably-produced fruits and vegetables. Organic, local, and small farm are the three cases used in the study. The research used a structured questionnaire to conduct an online survey of U.S. internet users with email addresses in the spring of 2011 with logit and ordered logit regression used as the analytical tools. Cost was the most important factor for consumers who did not purchase organic and local products more frequently while unavailability was the principal reason for not consuming produces from small farms. The study showed consumers of small farm products often (98.5 percent of the time) consume local fruits and vegetables also but not the other way around. The relevant socio-economic factors for determining organic purchasing frequency were gender, household size, and education. For small farm they were the ability to influence local change and the respondents’ frequency of purchase of local products. Socio-economic characteristics did not prove to be a factor in local purchasing decisions. Regular purchasers of organic fruits and vegetables provided a consistent perception of organic products with the USDA certified organic definition. Local consumers reported that taste and freshness are the most defining characteristics of local products while small farm consumers could not provide a clear picture of the definitional statements defining fruits and vegetables produced by a small farm. This implied that there is need for more work by small farm producers to differentiate themselves in the market. On the contrary, both local and organic producers have a clear point of differentiation to reach their customers. Industry marketing efforts can be greatly improved by focusing on the characteristics of the consumers they are trying to reach. Our results can be further investigated by completing the following recommendations. First, to conduct more targeted studies such as interviews or focus groups, second, to gain a deeper understanding of how consumers perceive these attributes and third to conduct a comprehensive study on the similarities and differences between small farm and local consumers.
