Abstract

Background

Evidence suggests that children in developing countries continue to openly defecate long after they are developmentally ready to be potty-trained, despite recent focus to increase access to improved sanitation facilities. In 2011, the Safe Squat potty training tool was piloted in rural Kenya to facilitate children's use of mud-floored pit latrines. The Safe Squat is a wooden platform that gives small children a temporary and secure ground that is easy to clean.

Goal

To determine the willingness to pay (WTP) for the Safe Squat in rural Kenya and inform future sales of the Safe Squat mat.

Methods

Four focus group discussions were conducted to inform the financial decision making of potential WTP survey participants. WTP surveys (using the Becker-Degroot-Marschak method to elicit WTP through an incentive-compatible bidding process) were carried out in homes of men and women who had been exposed to the mat from mothers who participated in the previous pilot (n=30); and in local markets where men and women might be interested in purchasing a Safe Squat (n=124).

Results

The surveys indicated a need for the Safe Squat - of the 445 children below 10 years of age in both surveys, 138 did not use the latrine unassisted. Of these, 53% of market children were reported to openly defecate, compared to 100% of home based children. Women perceived themselves to have a higher level of financial decision making power in regards to sanitation than did men of their wives. The Becker-Degroot-Marshak method had a low completion rate (in terms of participants who provided monetary offers), but this rate was much higher in home based surveys compared to the market based surveys (n=11/30 vs. n=11/124), indicating that participants previously exposed to the Safe Squat were more likely to purchase it. However, the overall WTP was higher in market based surveys (KSH 304/$3.50) than in home based surveys (KSH 199/$2.30).

Conclusion

Considerations for future marketing should be given toward men and women, emphasizing long term options to women; encouraging prior exposure to the Safe Squat; and selling the Safe Squat in settings where WTP is higher such as markets.
