The Use Of Semi-Structured Interviews For The Characterisation Of Farmer Irrigation Practices, Jimmy O’Keeffe, Wouter Buytaert, Ana Mijic, N. Brozovic, Rajiv Sinha

Daugherty Water for Food Global Institute: Faculty Publications

For the development of sustainable and realistic water security, generating information on the behaviours, characteristics, and drivers of users, as well as on the resource itself, is essential. In this paper we present a methodology for collecting qualitative and quantitative data on water use practices through semi-structured interviews. This approach facilitates the collection of detailed information on actors’ decisions in a convenient and cost-effective manner. Semi-structured interviews are organised around a topic guide, which helps lead the conversation in a standardised way while allowing sufficient opportunity for relevant issues to emerge. In addition, they can be used to obtain certain …

Our team identified the nine sectors considered most likely to present the strongest potential for development of DW, and landowners within these …

Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Rose Martin

Senior Honors Projects, 2010-2019

This study focuses on the environmental Value-Action Gap of students at James Madison University (JMU) in Harrisonburg, Virginia. This gap occurs when a person has pro-environmental beliefs but does not have congruent actions. Often, there are other factors apart from a person’s values that influence his/her willingness to participate in eco-friendly behavior (Howell 2013). For this study, the factor of influence being addressed is location. When students live on-campus at JMU they are surrounded by ‘green’ initiatives. Understanding the diffusion of environmental behavior from on-campus living to off-campus living is important because the majority of a JMU student’s residency is …

This is a heavily important topic of research as amphibians worldwide are declining related to many issues that stem from climate change and several other environmental issues of that nature. This study looked to use acidic pH within soil from western Nebraska to determine the reactionary impacts (primarily lesions) the western tiger salamander had after being subjected to it. It was found that pH did …

The Urban Heat Island Effect In Malta And The Adequacy Of Green Roofs In Its Mitigation, Jonathan Scicluna

Masters Theses, 2010-2019

Urbanisation is a reality of every major western society. The growth of cities, however, often results in major environmental impacts that not only effect the natural world but also humanity as well. One of these impacts is the Urban Heat Island (UHI) a phenomenon that influences the temperature inside built-up areas, often resulting in uncomfortably hot air temperature, especially in summer. However, as global climate change predictions keep forecasting warmer periods for regions such as Malta, UHI has the potential to transform from a nuisance to a deadly reality more often than in the present.

This work strives to get …

Applying The Water Governance Framework On Rural Water Development Projects In Guatemala, Muhanad M. Alkharaz

Theses and Dissertations

According to the Organization for Economic Cooperation and Development (OECD), ‘Water crisis is mainly a governance crisis’, (OECD, 2013). Many water experts, as individuals, organizations and even governmental bodies have developed water governance frameworks to overcome water challenges on local, national, and international levels such as Integrated Water Resource Management. In rural areas, especially in developing countries, access to safe drinking water is a daily challenge due to a variety of political, economic, and social constraints. For in-stance, some developing countries have a strong centralized governance system. Due to lack of capacity and resources, central governments are incapable of providing …

Haul Truck Tires Recycling, Jessica N. Lizarazu

Chemical Engineering Undergraduate Honors Theses

Do Insect Outbreaks Reduce The Severity Of Subsequent Forest Fires?, Garrett W. Meigs, Harold S.J. Zald, John L. Campbell, William S. Keeton, Robert E. Kennedy

Rubenstein School of Environment and Natural Resources Faculty Publications

Understanding the causes and consequences of rapid environmental change is an essential scientific frontier, particularly given the threat of climate- and land use-induced changes in disturbance regimes. In western North America, recent widespread insect outbreaks and wildfires have sparked acute concerns about potential insect-fire interactions. Although previous research shows that insect activity typically does not increase wildfire likelihood, key uncertainties remain regarding insect effects on wildfire severity (i.e., ecological impact). Recent assessments indicate that outbreak severity and burn severity are not strongly associated, but these studies have been limited to specific insect or fire events. Here, we present a regional …
