ABSTRACT: Water scarcity is already observed in several parts of the world, which can compromise life on the planet. This work uses system dynamics (SD) as a tool to estimate water consumption in the city of Florianópolis, southern Brazil. Using historical population, economy and water consumption data, a DS model is proposed to predict water consumption up to 2050. Through the Stella computer programme, policies to reduce water consumption in Florianópolis were tested. The model predicts reductions in water consumption of 37% (through the use of rainwater) and 4% (through awareness campaigns) for the year 2050. The model proposed can be used as a tool to support decisions to control and reduce water consumption in large cities.
