In this third episode of the Memory and Water theme entitled “Water management in the neighborhood: The traces of water through its ruins”, we present a dialogue with 4 voices departing from questions about their experiences in relation to the relevance that decisions have and have had for water management in communities, cities and territories. The beauty of a ruin not only as that, but as an accumulation of knowledge and memory to defend our life in the present. Many thanks to Atahualpa Caldera, Graciela Cruz and Cinthia Miranda from the University of Guadalajara. We are not alone!
