Soil conservation efforts in Indonesia since the Dutch colonial era have focused on introducing bench terraces—a costly soil conservation method for poor, upland farmers. Data from two villages in the Kerinci uplands of Sumatra illustrate that even with state underwriting of bench terrace construction, farmers across all economic strata still resist using this method.
