Abstract

A water allocation model at farm-scale was developed to interpret water allocation patterns in an intensive agriculturaldistrict of Southern Italy, supplied by groundwater and surface waters (from reservoir) with variable costs and distinctmanagement regimes. The model aims at evaluating the impact of farm-scale water costs on water resourcesmanagement and groundwater conservation at district scale. Semi-structured interviews were carried out involvinglocal stakeholders to define (i) the relationship between irrigation source selection and water tariff applied by theirrigation district, and (ii) the conjunctive use of groundwater based on water cost convenience. It was demonstratedthat farmers' choice depends on the ratio between volumetric water tariff and the groundwater pumping cost at farmscale.The results also demonstrated that a restrictive water tariff policy applied during drought periods produced anincrease in the groundwater use instead of reducing the water consumption. The model allowed to analyze the driversinfluencing farmers' behaviour, thus assessing the effectiveness of water protection policies, specifically those relatedto water tariff.
