Willingness to pay for a Rift valley fever (RVF) vaccine among Kenyan cattle producers

Preventive Veterinary Medicine, 2019
A double bounded contingent valuation (CV) model was used to assess the Willingness to Pay (WTP) for vaccination of cattle against RVF in a sample of 276 livestock producers in Murang'a, Laikipia and Kwale Counties. While the level of awareness about the disease was rather low, nearly all respondents expressed willingness to have their animals ...
