“…Although many such research projects are funded by such institutions as the World Bank and have produced a large number of technical papers (e.g. Crabbe & Smith, 2006;Jennings, Seymour, & Dunstone, 2006;May, 2005), a significant contribution to the understanding of sustainability at the micro-level has been achieved through the use of volunteers working on small-scale scientific projects The concept of volunteering has a long and established history in many subject (Stebbins, 1992;Stebbins & Graham, 2004;Uriely, Reichel, & Ron, 2003) areas; the volunteering literatures closest to tourism are: leisure (Parker, 1992), sport (Coleman, 2002;Cuskelly & Harrington, 1997;Gratton & Kokolakakis, 1997;Sport England, 1996 and events (Johnston, Twynam, & Farrell, 1999;Ralston, Lumsdon, & Downward, 2005;Solberg, 2003). The literature linked to volunteer tourism is fragmented with studies spanning a range of topics, for example: culture (McIntosh & Zahra, 2005); cultural exchange (Lyons, 2003); spirituality (Zahra, 2006); pilgrimage (Mustonen, 2005;Singh & Singh, 2004); self (Wearing, 2002(Wearing, , 2003Wearing & Deane, 2003;Wearing & Neil, 2000); self development (Uriely et al, 2003); and environment and conservation (Broad, 2003;Ellis, 2003;Halpeny & Caissie, 2003;Ryan, Kaplan, & Grese, 2001;Weston, Fendley, Jewell, Satchell, & Tazaros, 2003).…”
