World Water Day is observed on March 22 since 1993 when the United Nations General Assembly declared March 22 as World Day for Water.

Many places in Mexico have established a tradition of celebrating World Water Day with a parade of pre-school children in costumes emphasizing the importance of the natural world and its diversity of life forms. We first observed this event in Colima in 2001. In Querétaro this year we were fortunate to be present for another children's Water Day event, in the Plaza de Armas, the main square in the city. Children paraded around the square several times, accompanied by a "virtual band" - a portable sound system with loudspeakers on a tall pole. As they gathered for the parade, they sang songs and marched around potted plants. Then they were all given whistles, thus producing another raucous accompaniment. We love this event, and the care that it expresses for the children and their appreciation of life and the water resources essential to life.
