Determining Farmers’ Willingness to Pay for Irrigation Water in the Alentejo Region (Southern Portugal) by the Residual Value Method

This paper aims to determine farmers’ willingness pay for irrigation water, using the residual value method, most representative crops at six Irrigation Communities from Alentejo region, southern Portugal. The main objective of this assessment was that farmers would be able water irrigate different locations, and show approach can used provide information about farming economic sustainability support on if crop prices need revised or a national policy should conceived cover costs. results vegetables fruit trees have highest Residual Value Water (RVW), while Wheat, Sunflower, Fodder crops, Semi-intensive Olive Orchards Rice tend an RVW lower than current variable price. also that, while, Melon, Tomato, Onion, Super-high-density Orchards, Peach Almonds, both yields price may decrease significantly, allowing one save faming inputs, Sunflower require increase in
