Abstract
In flat environments, groundwater is relatively shallow, tightly
associated with surface water and climate, and can have either positive
and negative impacts on natural and human systems depending on its
depth. A linked modelling and analysis framework that seeks to capture
linkages across multiple scales at the climate/water/crop nexus in the
Argentine Pampas is presented. This region shows a strong coupling
between climate, soil water, and land use due to its extremely flat
topography and poorly developed drainage networks. The work describes
the components of the framework and, subsequently, presents results from
simulations performed with the twin goals of (i) validating the
framework as a whole and (ii) demonstrating its usefulness to explore
interesting contexts such as unexperienced climate scenarios (wet/dry
periods), hypothetical policies (e.g., differential grains export
taxes), and adoption of non-structural technologies (e.g., cover crops)
to manage water table depth.
