13 pages, In Ghana, groundwater, accessed through wells and boreholes, is generally unregulated and may be contaminated with pollutants including excess nitrates from agricultural chemical fertilizers. Yet, studies estimating how clean groundwater is valued are not available in Ghana. In addition, some research suggests that the pre-experiment information provided to survey respondents affects their valuation of an identical outcome. This paper estimates smallholder farmers’ preferences for groundwater protection using pre-experiment information focused on one of two outcomes: environment or health. The double-bounded contingent valuation (DBCV) approach is used to estimate willingness to pay (WTP) to protect groundwater quality. The estimation accounts for shift and anchoring effects, which are common issues with the DBCV method. The mean WTP from the health (environmental) information subsample is about US$19 (US$17) per acre, and the values are significantly different between the information conditions. The findings shed light on the importance of using precise information in eliciting WTP in a developing country setting.

James F. Evans Collection, All of the 100 county Extension offices in Iowa have a set of six water quality videotapes available for use by clientele. The state water quality Extension specialist designed the high quality tapes, each 20 minutes long, to be viewed at home by clients who had water questions. The question was: "Should video by used again as an educational delivery method?" Responses to a telephone survey of county office assistants indicated a wide variation in the use of video tapes, although over 75% liked the idea of information via tapes. The counties needed assistance with publicity and displays, something that area media specialists might provide. (original)
