Cost-sharing rules over an irrigation ditch between
head-enders and tail-enders were also discussed by Aadland and Kolpin (2004) in their econometric analysis based
on fundamental GT concept from two surveys in south –central Montana, USA. Formulating water allocation
decisions as a cooperative game in irrigated land of Kat River Basin in South Africa is surveyed by Dinar et al
(2006). They compared their results with the results from a Role Playing Game and discussed the differences in
these two procedures. Based on results of Dinar et al. (2006), a similar comparison between these two methods
regarding common property water allocation among farmers in the Kat River Basin was made by Désolé (2007) in
order to provide insights on the issue of game contextualization
