Excerpt from Natural Vegetation of Casa Grande Ruins National Monument, Arizona The monument was established in 1918. The land was never plowed during historic times, although it is currently surrounded by groundwater and river-irrigated agriculture. The boundary was fenced to protect it from livestock grazing in 1934. Decline of the water table caused the native mesquite trees to die during the 19405 (judd It is conceivable that the effects of grazing, water table decline, and possibly pesticide drift from aerial spraying of nearby cotton fields have reduced or eliminated other floral elements as well.

Evolution of Water Supply Through the Millennia presents the major achievements in the scientific fields of water supply technologies and management throughout the millennia. It provides valuable insights into ancient water supply technologies with their apparent characteristics of durability, adaptability to the environment, and sustainability. A comparison of the water technological developments in several civilizations is undertaken. These technologies are the underpinning of modern achievements in water engineering and management practices. It is the best proof that “the past is the key for the future.” Rapid technological progress in the twentieth century created a disregard for past water technologies that were considered to be far behind the present ones. There are a great deal of unresolved problems related to the management principles, such as the decentralization of the processes, the durability of the water projects, the cost effectiveness, and sustainability issues such as protection from floods and droughts. In the developing world, such problems were intensified to an unprecedented degree. Moreover, new problems have arisen such as the contamination of surface and groundwater. Naturally, intensification of unresolved problems led societies to revisit the past and to reinvestigate the successful past achievements. To their surprise, those who attempted this retrospect, based on archaeological, historical, and technical evidence were impressed by two things: the similarity of principles with present ones and the advanced level of water engineering and management practices. Evolution of Water Supply Through the Millennia is intended for engineers in water resources companies, hydraulic design companies, and water Institutes. It can be used for all courses related to water resources. Authors: Andreas N. Angelakis, Institute of Iraklion, National Foundation for Agricultural Research (N.AG.RE.F.), Greece, Larry W.

The cult-y pocket-size field guide to the strange and intriguing secrets of the Mojave—its myths and legends, outcasts and oddballs, flora, fauna, and UFOs—becomes the definitive, oracular book of the desert For the past five years, Desert Oracle has existed as a quasi-mythical, quarterly periodical available to the very determined only by subscription or at the odd desert-town gas station or the occasional hipster boutique, its canary-yellow-covered, forty-four-page issues handed from one curious desert zealot to the next, word spreading faster than the printers could keep up with. It became a radio show, a podcast, a live performance. Now, for the first time—and including both classic and new, never-before-seen revelations—Desert Oracle has been bound between two hard covers and is available to you. Straight out of Joshua Tree, California, Desert Oracle is “The Voice of the Desert”: a field guide to the strange tales, singing sand dunes, sagebrush trails, artists and aliens, authors and oddballs, ghost towns and modern legends, musicians and mystics, scorpions and saguaros, out there in the sand. Desert Oracle is your companion at a roadside diner, around a campfire, in your tent or cabin (or high-rise apartment or suburban living room) as the wind and the coyotes howl outside at night. From journal entries of long-deceased adventurers to stray railroad ad copy, and musings on everything from desert flora, rumored cryptid sightings, and other paranormal phenomena, Ken Layne's Desert Oracle collects the weird and the wonderful of the American Southwest into a single, essential volume.
Two men played a crucial role in the creation and early history of the National Park Service: Stephen T. Mather, a public relations genius of sweeping vision, and Horace M. Albright, an able lawyer and administrator who helped transform that vision into reality. In Creating the National Park Service, Albright and his daughter, Marian Albright Schenck, reveal the previously untold story of the critical "missing years" in the history of the service. During this period, 1917 and 1918, Mather's problems with manic depression were kept hidden from public view, and Albright, his able and devoted assistant, served as acting director and assumed Mather's responsibilities. Albright played a decisive part in the passage of the National Park Service Organic Act of 1916; the formulation of principles and policies for management of the parks; the defense of the parks against exploitation by ranchers, lumber companies, and mining interests during World War I; and other issues crucial to the future of the fledgling park system. This authoritative behind-the-scenes history sheds light on the early days of the most popular of all federal agencies while painting a vivid picture of American life in the early twentieth century.
