A Framework For Incorporating The Impact Of Water Quality On Water Supply Stress: An Example From Louisiana, David M. Borrok, Jian Chen, Hisham Eldardiry, Emad Habib

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Water of poor quality can directly impact the budget of water available for key user groups. Despite this importance, methods for quantifying the impact of water quality on water availability remain elusive. Here, we develop a new framework for incorporating the impact of water quality on water supply by modifying the Water Supply Stress Index (WaSSI). We demonstrate the usefulness of the framework by investigating the impact of high salinity waters on the availability of irrigation water for agriculture in Louisiana. The WaSSI was deconstructed into sectoral components such that the total available water supply could be reduced for a …

Best Management Practices: A Community-Based Approach To Construction And Installation, Nathanael J. La Breche

Purdue Journal of Service-Learning and International Engagement

The Wabash River Enhancement Corporation (WREC) is a nonprofit organization dedicated to improving both the health of the Wabash River and the surrounding terrestrial areas. In an effort to improve water quality, their urban cost-share program focuses on supporting green projects within a critical region surrounding the Great Bend of the Wabash River. In this essay, a Purdue student describes his experience as leader of a six-member group who worked with WREC to locate a suitable site within this critical area and implement a green project. They selected the Lighthouse Baptist Church, located in Lafayette, Indiana, since it was experiencing …

Can Facebook Aid Sustainability? An Investigation Of Empathy Expression Within The Humans Of New York Blog, Hannah Wheeler, Courtney Quinn

Earth and Environmental Sciences Publications

This qualitative study offers a novel exploration of the links between social media, virtual intergroup contact, and empathy by examining how empathy is expressed through interactions on a popular social media blog. Global leaders are encouraging individuals to engage in behaviors and support policies that provide basic social foundations. It is difficult to motivate people to undertake such actions. However, research shows that empathy intensifies motivation to help others. It can cause individuals to see the world from the perspective of stigmatized group members and increase positive feelings. Social media offers a new pathway for virtual intergroup contact, providing opportunities …

Effects Of Switchgrass Related Land-Use Changes On Aquatic Macroinvertebrates, Latha Malar Baskaran

Doctoral Dissertations

This research examines if switchgrass-based land-management practices have the potential to influence aquatic macroinvertebrates through changes in stream flow and water quality. The number of taxa in Ephemeroptera, Plecoptera, and Trichoptera orders (EPT taxa richness/EPT-TR) is analyzed as an aquatic macroinvertebrate bioindicator in the context of regional environmental effects, and changes in stream flow and water quality. This dissertation is structured as three manuscripts that link together to address the overall research question.

The first manuscript focuses on identifying regional environmental variables that influence EPT-TR across ecoregions in Tennessee. The influences of temperature, precipitation, geology, soil, stream flow and velocity …

The Importance Of Traditional Ecological Knowledge In Agroecological Systems In Peru, Christina R. Saylor, Kamal Alsharif, Hannah Torres

School of Geosciences Faculty and Staff Publications

This study argues that a critical element in the success of an ecosystem service (ES) approach at any level is the higher qualitative valuation of local traditional ecological knowledge (TEK). As such, the objectives of this research were to illustrate the role of TEK in agroecological systems in Peru and to develop recommendations about this type of knowledge acquisition. The data were gathered using interviews and focus groups with subsistence farmers along with key informant interviews to elicit TEK at local and regional scales in five provinces in the Lake Titicaca region of Puno, Peru. Qualitative analysis revealed dominant themes …
