Abstract
Water resources sustainable management will be one of the major issues that need to be attempted globally in the next decades.Especially south of the Alps, climate projections suggest a strong impact on water resources availability and distribution in space and time. Agriculture would be the most sensitive sector to changing water availability: under warmer climate, crops would be more water-demanding to sustain the evapotranspiration during the growing season. The integrated use of ground- and surface water resources will have a key role in mitigating climate change impact.With the final aim of exploring such possibility, an irrigation-system model (IdrAgra) was coupled with a groundwater flow model (MODFLOW2000), applying it to an area including a portion of the Muzza-Bassa Lodigiana irrigation district in Lombardy. Downscaled projected meteorological data (2080-2099) were applied to the coupled model to estimate changes in the resource availability under climatechange scenarios. Results would represent the starting point for the implementation of alternative integrated water resource management policies in agricultural environment.
