The High Plains region was once called the Great American Desert and thought to be, in the words of explorer Stephen Long, “wholly unfit for cultivation.”Now we know that beneath the surface, unbeknownst to the explorers and early settlers, lies the Ogallala aquifer, an underground formation that stretches for 800 miles from the Texas panhandle to South Dakota. It holds more water than Lake Huron. Indeed, the Ogallala has been referred to as the sixth Great Lake. It is the water pumped for irrigation from the Ogallala that has enabled a naturally dry region to produce up to 40 percent of America’s beef and 20 to 25 percent of its food and fiber, an output worth about $20 billion.In the forty years since the invention of center pivot irrigation, the High Plains aquifer system has been depleted at an astonishing rate. In 1978 the volume of water pumped from the aquifer exceeded the annual flow of the Colorado River. In Texas, water levels are down 200 feet in some areas. In Kansas, 700 miles of rivers that once flowed year round no longer flow at all. In short, the High Plains may be becoming the desert it was once thought to be. Is it too late to solve the problem?Geographers David Kromm and Stephen White assembled nine of the most knowledgeable scholars and water professionals in the Great Plains to help answer that question. The result is a collection of essays that insightfully examine the dilemmas of groundwater use. From a variety of perspectives they address both the technical problems and the politics of water management to provide a badly needed analysis of the implications of largescale irrigation. They have included three case studies: the Nebraska Sand Hills, Northwestern Kansas, and West Texas. Kromm and White provide an introduction and conclusion to the volume.

An intimate reckoning with aquifer depletion in America's heartlandThe Ogallala aquifer has nourished life on the American Great Plains for millennia. But less than a century of unsustainable irrigation farming has taxed much of the aquifer beyond repair. The imminent depletion of the Ogallala and other aquifers around the world is a defining planetary crisis of our times. Running Out offers a uniquely personal account of aquifer depletion and the deeper layers through which it gains meaning and force.Anthropologist Lucas Bessire journeyed back to western Kansas, where five generations of his family lived as irrigation farmers and ranchers, to try to make sense of this vital resource and its loss. His search for water across the drying High Plains brings the reader face to face with the stark realities of industrial agriculture, eroding democratic norms, and surreal interpretations of a looming disaster. Yet the destination is far from predictable, as the book seeks to move beyond the words and genres through which destruction is often known. Instead, this journey into the morass of eradication offers a series of unexpected discoveries about what it means to inherit the troubled legacies of the past and how we can take responsibility for a more inclusive, sustainable future.An urgent and unsettling meditation on environmental change, Running Out is a revelatory account of family, complicity, loss, and what it means to find your way back home.

Water scarcity is a critical issue for agriculture, and, hence, efficient management and conservation practices for agricultural water use are essential for adapting to and mitigating the impacts of current and future discrepancy between water supplies and water demands. This Special Issue focuses on “Agricultural Water Conservation: Tools, Strategies, and Practices”, which aims to bring together a collection of recent cutting-edge research and advancements in agricultural water conservation. The Special Issue intends to give a broad overview focusing on on-farm water conservation practices, advanced irrigation tools and water technologies, and the best management practices and strategies for efficient water use in agriculture.
