Water and Environment Journal, Volume 39, Issue 3, Page 275-289, August 2025.Abstract This study employs a double‐bounded dichotomous choice contingent valuation experiment to investigate the willingness to pay (WTP) of 313 Egyptian smallholder farmers in the Nile Delta region for improved irrigation services. The results from probit and bivariate probit models reveal an inverse relationship between water price and WTP ...
