“…CP was a poorly performing development project that was improved through a collaborative effort between University of Virginia and University of Venda students and faculty with substantial community support (Harshfield et al 2009; Heil et al 2010). CP consists of a series of pipes that brings stream water down from hills behind the communities to a storage tank, where it may be chlorinated and sent to standpipes in selected households.…”

Coliform Sources and Mechanisms for Regrowth in Household Drinking Water in Limpopo, South Africa

Resource-limited communities throughout the developing world face significant environmental health problems related to the myriad of coliform sources within those communities. This study comprehensively investigated contamination sources and the biological and chemical mechanisms sustaining them in two adjacent communities in rural Limpopo, South Africa. An 8-month study was conducted of household (n = 14) and source water quality, measurements of biofilm layers on the inside of household water storage containers and water transfer devices, and also hand-based coliforms and hand-washing effectiveness. A 7-day water container incubation experiment was also performed to determine the biological and chemical changes that occur in a household water storage container independent of human interference. Results indicate that household drinking water frequently becomes contaminated after collection but before consumption (197 versus 1,046 colony-forming units/100 mL; n = 266; p < 0.001). The most important contamination sources include biofilm layers on the inside of storage containers (1.85 ± 1.59 colony-forming units/cm2; n = 44), hands (5,097 ± 2,125 colony-forming units/hand; n = 48), and coliform regrowth resulting from high assimilable organic carbon (AOC) levels during storage. A maximum specific growth rate, μmax, of 0.072 ± 0.003 h−1 was determined for total coliform bacteria on AOC, and a high correlation between AOC concentrations and the growth potential of total coliform bacteria was observed. These results support the implementation of point-of-use water treatment and other interventions aimed at maintaining the safe water chain and preventing biological regrowth.

“…In particular, the wiki Appropedia has been used for service learning support (Pearce, et al 2008;Pearce, 2009) and is particularly well suited as a model. Recent examples of OSAT development in classrooms include: water filtration systems (Heil, et al, 2010), wind powered LED lighting (Thomas, 2007), and AT wheelchairs (Winter, 2006). The operations of most ATs are governed by physical laws taught in introductory physics and engineering classes, which make the technological development accessible to the students.…”

The technological evolution of the 3-D printer, widespread internet access and inexpensive computing has made a new means of open design capable of accelerating self-directed sustainable development. This study critically examines how open source 3-D printers, such as the RepRap and Fab@home, enable the use of designs in the public domain to fabricate open source appropriate technology (OSAT), which are easily and economically made from readily available resources by local communities to meet their needs. The current capabilities of open source 3-D printers is reviewed and a new classification scheme is proposed for OSATs that are technically feasible and economically viable for production. Then, a methodology for quantifying the properties of printed parts and a research trajectory is outlined to extend the existing technology to provide complete village-level fabrication of OSATs. Finally, conclusions are drawn on the potential for open source 3-D printers to assist in driving sustainable development.

“…The archival and 6-month post-travel interviews also resulted in a dimension of the findings which speak to more distal outcomes. When given the opportunity to express the extent to which participation in ESAVANA coursework has influenced academic and/or professional trajectories, many students offered evidence of subsequent community-based research projects, at least eight of which have resulted in undergraduate, cross-cultural, peer-reviewed publications (Brown-Glazner et al, 2010;Harshfield et al, 2009;Heil et al, 2010). In addition, both UVa and southern African participants cited the ways in which their roles as undergraduate student leaders were enhanced through participation in PCESA, emphasizing that it was not what they were leading or collaborating on that was important, so much as how.…”

Literature related to post-secondary education suggests that institutions of higher education have at their core 'a civic mission that calls on faculty, students, and administrators to apply their skills, resources, and talents to address important issues affecting communities, the nation, and the world' conceptualized as 'engaged scholarship' (Stanton, 2008). In this article we illustrate the ways in which one study abroad program embraces a model of engaged scholarship though connections to a broader cross-cultural and interdisciplinary network. We demonstrate how long-term international collaborations and field-based experiential learning opportunities between US and southern African institutions reflect core principles of relationships, respect and reciprocity, providing opportunities for purposeful and culturally grounded transformative student learning experiences. One key aspect of this network was to design study abroad opportunities that create pedagogical alternatives that influence civic identity development, build cultural competence, enhance notions of citizenship, and emphasize community engagement. This article presents the findings from a formative evaluation of the experiences of a number of the undergraduate students and others who have participated in the study abroad component of this network.
