Abstract

Urban areas are insecure from the food point of view, since non-agricultural land use is a priority, necessitating the daily import of food, some with high water requirements in their production, such as bananas (Musa ssp.). The concept Virtual Water applies to the hidden volume of water in any production, it is necessary to know this volume to better manage the water resources, even more if the production is exported. The water capacity of the Cariri Valley was analyzed in order to withstand the pressure exerted by agribusiness companies practicing irrigated banana farming. The research approached the concept of Virtual Water, and from satellite images, climatological data and geoprocessing software, the water consumption in the irrigated areas was calculated, obtaining the volume of Virtual Water that is exported to other regions of Brazil through the banana, showing that this activity is unsustainable.
