Análisis de la sustentabilidad del uso del recurso hídrico bajo tres estilos de producción hortícola en el Cinturón Hortícola Platense

| Sumario: | In La Plata horticultural region, Argentina, different production systems (conventional and organic greenhouses, organic and conventional outdoor with different degrees of intensification) coexists, which use different amounts of water and produce different potential impacts on their quality. In these systems the volumes of groundwater extracted to irrigate crops of tomato (Lycopersicon esculentum Mill.) and lettuce (Latuca sativa L.) and the potential impact on the quality of the resource were analyzed. The perception of farmers and technicians on water was also considered. A system approach and a strong sustainability criteria was taken into account. The different production systems differs both in water requirements for irrigation and on the potential impact on water quality.\nGreenhouse system used a higher volume of groundwater than outdoors crops, defining greater pressure on underground water sources. Greenhouse agriculture was less efficient in using water than those made outdoors.\nConventional outdoor productions had superior potential for deterioration in water quality due to their great leaching risk of pesticides and nitrates. Meanwhile, perception on water resources by farmers does not seem appropriate for achieving sustainable management thereof. It concludes that it is necessary to review the current production paradigm since it endangers the possibility of meeting the most basic needs: drinking water and foods produced with it. |
