Agriculture is one of the most vulnerable economic sectors to the impacts of climate change, specifically those related with expected changes in water availability.  By using a hydro-economic model, this study assesses the distributional impacts of climate change, considering the geographical location of each farmer’s community and the spatial allocation of water resources at basin scale.  A hydrological model, the Soil and Water Assessment Tool model, describes the basin hydrology, while farmers’ economic responses are represented using a non-linear agricultural supply model.&nbs
