Resumen
Based on numerical simulations with a distributed in space, continuous in time, and properly calibrated and verified hydrological model, it is shown that though the increase in rainfall is the prime phenomenon explaining the increase in groundwater levels in the Argentine Pampas, one of the largest plains throughout the world, the trend towards agriculturization also plays a very significant role; moreover, the non-linear response of the hydrological system to changes in precipitation and land use is put into evidence, as the combination of both effects produces a result that is much less intense than the sum of each of the individual effects by themselves.
