Agrohydrological analysis of groundwater recharge and land use changes in the Pampas of Argentina
This paper studies the changes of groundwater, climate and land use in the Pampas of Argentina. These changes offer opportunities and threats. Lowering groundwater without irrigation causes drought and successive crop and yield damage. Rising groundwater may alleviate drought as capillary rise sup...

| description | This paper studies the changes of groundwater, climate and land use in the Pampas of Argentina. These changes
offer opportunities and threats. Lowering groundwater without irrigation causes drought and successive crop
and yield damage. Rising groundwater may alleviate drought as capillary rise supports root water uptake and
crop growth, thus narrowing the difference between potential and actual yields. However, rising groundwater
may also limit soil water storage, cause flooding in metropolitan areas and have a negative impact on crop
yields. Changing land use from continuous soy bean into crop rotations or natural vegetation may decrease
groundwater recharge and thus decrease groundwater levels. In case of crop rotation however, leaching of
nutrients like nitrate may increase.
We quantified these impacts using integrated dynamic crop growth and soil hydrology modelling. The models
were tested at field scale using a local dataset from Argentina. We applied distributed modelling at regional scale
to evaluate the impacts on groundwater recharge and crop yields using long term weather data.
The experiments showed that threats arise from continuous monotone land use. Opportunities are created
when a proper balance is found between supply and demand of soil water using a larger differentiation of land
use. Increasing the areas of land use types with higher evapotranspiration, like permanent grassland and trees,
will contribute to a more stable hydrologic system with more water storage capacities in the soil system and
lower groundwater levels.
Modelling tools clearly support the evaluation of the impact of land use and climate change on groundwater
levels and crop yields. |
