Resumen:
The aims of this work are to provide an overview of the current stresses
of estuaries in Argentina and to propose adaptation strategies from an
ecohydrological approach. Several Argentinian estuaries are impacted by
pollutants, derived mainly from sewage discharge and agricultural or
industrial activities. Anthropogenic impacts are expected to rise with
increasing human population. Climate-driven warmer temperature and
hydrological changes will alter stratification, residence time, oxygen
content, salinity, pollutant distribution, organism physiology and
ecology, and nutrient dynamics. Good water quality is essential in
enhancing estuarine ecological resilience to disturbances brought on by
global change. The preservation, restoration, and creation of wetlands
will help to protect the coast from erosion, increase sediment accretion
rates, and improve water quality by removing excess nutrients and
pollutants. The capacity of hydrologic basin ecosystems to absorb human
and natural impacts can be improved through holistic management, which
should consider social vulnerability in complex human-natural systems.
