Commonly, we think of soil as just a medium to walk above or build upon. If we had the ability to shrink ourselves to the size of a soil particle, we would be amazed at the vibrant life and ever-changing interactions taking place all around us. The activity, physical changes and diverse life forms would overwhelm the senses. Soil moisture fuels this activity. The soil and water dynamic together as one entity is both the introduction and ending of a novel on the living. Where time is a method used to record events, the soil-water dynamic is time. Together, they tell us where we've been and point us in the direction we need to go. Retaining Soil Moisture in the American Southwest is a culmination of the author's extensive interest in soil and water interactions, soil remediation, land application of treated wastes, conservation, air, soil, and water quality issues, and an overall appreciation for improvement for the quality of life. Awareness of the players in the soil-water-plant continuum aids in understanding the processes that either reduce or conserve soil moisture. The dry climate of the American Southwest demands this understanding to ensure that waters which may have taken hundreds to thousands to millions of years to amass are not wiped out in the span of a generation.

ON THE COVER: A portion of a painting entitled Rain by Howard Behling Schleeter from the book, A More Abundant Life, New Deal Artists and Public Art in New Mexico, published by Sunstone Press. The original painting is in the collection of Melrose High School, Melrose, New Mexico.

The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Histories of Maize is the most comprehensive reference source on the botanical, genetic, archaeological, and anthropological aspects of ancient maize published to date.

In recent decades, the study of groundwater flow and solute transport has advanced into new territories that are beyond conventional theories, such as Darcy’s law and Fick’s law. The studied media have changed from permeable porous and fractured ones to much less permeable ones, such as clay and shale. The studied pore sizes have also changed from millimetres to micro-meters or even nano-meters. The objective of this Special Issue is to report recent advances in groundwater flow and solute transport that push the knowledge boundary into new territories which include, but are not limited to, flow and transport in sloping aquifer/hillslopes, coupled unsaturated and saturated flow, coupled aquifer-vertical/horizontal/slant well flow, interaction of aquifer with connected and disconnected rivers, non-Darcian flow, anomalous transport beyond the Fickian scheme, and flow and transport in extremely small pore spaces such as shale and tight sandstones. Contributions focusing on innovative experimental, numerical, and analytical methods for understanding unconventional problems, such as the above-listed ones, are encouraged, and contributions addressing flow and transport at interfaces of different media and crossing multiple temporal and spatial scales are of great value

It’s all but certain that the next fifty years will bring enormous, not to say cataclysmic, disruptions to our present way of life. World oil reserves will be exhausted within that time frame, as will the lithium that powers today’s most sophisticated batteries, suggesting that transportation is equally imperiled. And there’s another, even more dire limitation that is looming: at current rates of erosion, the world’s topsoil will be gone in sixty years. Fresh water sources are in jeopardy, too. In short, the large-scale agricultural and food delivery system as we know it has at most a few decades before it exhausts itself and the planet with it. Farming for the Long Haul is about building a viable small farm economy that can withstand the economic, political, and climatic shock waves that the twenty-first century portends. It draws on the innovative work of contemporary farmers, but more than that, it shares the experiences of farming societies around the world that have maintained resilient agricultural systems over centuries of often-turbulent change. Indigenous agriculturalists, peasants, and traditional farmers have all created broad strategies for survival through good times and bad, and many of them prospered. They also developed particular techniques for managing soil, water, and other resources sustainably. Some of these techniques have been taken up by organic agriculture and permaculture, but many more of them are virtually unknown, even among alternative farmers. This book lays out some of these strategies and presents techniques and tools that might prove most useful to farmers today and in the uncertain future.

The history of science discipline is contributing valuable knowledge of the culture of soil understanding, of the conditions in society that fostered the ideas, and of why they developed in certain ways. This book is about the progressive "footprints made by scientists in the soil. It contains chapters chosen from important topics in the development of soil science, and tells the story of the people and the exciting ideas that contributed to our present understanding of soils. Initiated by discussions within the Soil Science Society of America and the International Union of Soil Sciences, this book uniquely illustrates the significance of soils to our society. It is planned for soils students, for various scientific disciplines, and for members of the public who show an increasing interest in soil. This book allows us to answer the questions: "How do we know what we know about soils? and "How did one step or idea lead to the next one?The chapters are written by an international group of authors, each with special interests, bound together by the central theme of soils and how we came to our present understanding of soils. Each concentrate on soil knowledge in the western world and draw primarily on written accounts available in English and European languages. Academics, graduate students, researchers and practitioners will gain new insights from these studies of how ideas in soil science and understanding of uses of soils developed.* Discusses tracing soils knowledge accumulated from Roman times, first by soil users and after 1800s by scientists* Offers ideas about how soils knowledge was influenced by the social context and by human needs* Combines the history of ideas with scientific knowledge of soils* Written by chapter authors who combine subject matter expertise with knowledge of practical soil uses, and provide numerous references for further study of the relevant literature

This book aims to come up with views to address the queries of planners, policymakers, and general people for water resources management under uncertainty of climate change, including examples from Asia and Europe with successful adaptive measures to change the challenge of climate change into opportunities. The availability of clean water is a major global challenge for the future due to a rapidly growing population and urbanization where further stress in water resources is expected due to the impact of climate change. The wide range of impacts includes for example changes in hydrology, moisture availability, spatial and temporal variations in magnitude of stream flow, and dwindling of water levels with adverse effect on wetlands and ecosystem. As a consequence, water management has become a serious issue and was identified as a global societal challenge, and climate change forecasting has become one of the key issues in recent research on sustainable water resources management.

Annotation. Inscribed Landscapes explores the role of inscription in the social construction of place, power, and identity. Bringing together twenty-one scholars across a range of fields-primarily archaeology, anthropology, and geography-it examines how social codes and hegemonic practices have resulted in the production of particular senses of place, exploring the physical and metaphysical marking of place as a means of accessing social history.

Covers varying opinions on greenhouse gases, discussing their sources, effect on the environment, role in global warming, and how they can be curbed.
