This book takes readers on a journey through the history of water in the Coahuila desert. It starts by describing the beauty and mysteries of the landscape, and then explores the rock art of the original desert cultures in Coahuila, offering readers a glimpse of the sacred nature of water in the desert, as well as the rituals surrounding it. Moving on to the colonial times and the post- independence development of the region, it discusses early water management, and explores how water is managed in modern times, as well as the legal complications of the law, and how these faulty laws, designed for less arid regions, have affected a highly diverse wetland, the Cuatro Ciénegas oasis. The book then examines the biological consequences of the water loss for the aquatic plants and animals in Churince – a now extinct system within Cuatro Ciénegas. Further, it addresses how even bacteria can become extinct in this hyper-diverse microbial oasis. Lastly, after this despair and sense of loss, the book provides hope, offering suggestions for how we can transform the future, from a social and educational point of view as well as through good science and changes in policy.
