Resumo

Este trabalho teve como objetivo avaliar o potencial de utilização de esgoto tratadona irrigação de sete culturas produzidas no estado de Santa Catarina, avaliando a demanda atual de água para irrigação na área de estudo e a produção futura de esgoto tratado. Os dados de produção de alimentos foram coletados por intermédioda instituição agrícola pública mais importante presente na área de estudo para calcular sua pegada hídrica azul, dada a quantidade de alimentos colhidos. Osdados de produção futura de esgoto tratado foram recolhidos a partir de relatóriosoficiais que apresentam os planos de saneamento a serem executados até 2035. Ferramentas de sistema de informação geográfica e princípios de avaliação de risco foram utilizados para apresentar e discutir resultados de perspectivasquantitativas e qualitativas. Os resultados mostram que a quantidade de esgototratado a ser produzida em 2035 poderia não apenas suprir a demanda atual de água para irrigação das culturas selecionadas, mas também permitir a expansão da agricultura sem consumir mais água potável.
