Resumo

Introdução: No atual contexto de alterações globais, a água é um bem escasso em muitas realidades geográficas. A educação da população jovem tem um papel particularmente relevante, na gestão sustentável da água.

Objetivos: Estimar a Pegada Hídrica (PH) em jovens, incluindo os usos diretos e indiretos de água. Desenvolver uma aplicação educacional, para mostrar medidas simples de poupança de água nas suas atividades diárias.
Métodos: Foram desenvolvidos dois questionários, o primeiro para calcular a PH dos jovens, e o segundo para servir de base ao jogo educacional. Participaram 82 estudantes entre os 12 e os 15 anos.

Resultados: A PH média nos jovens é de 3223 ± 830 L/dia. Os usos indiretos de água são cerca de dez vezes superiores aos usos diretos. Nos usos indiretos, a alimentação representa a maior parte da PH (84.4 %) e em 2º lugar vêm os relacionados com o vestuário (6.4%). Nos grupos de alimentos estudados, a carne representa a maior contribuição (39.6% da PH). Para ambos os sexos, o elevado consumo direto de água (aprox. 264 L/dia) é devido a duches prolongados.

Conclusões: Os jovens estão a consumir demasiada água, devendo rever hábitos na alimentação, no vestuário, e na duração dos duches diários.
