Available in PDF, EPUB and Kindle. Book excerpt: IRRIGATION FUNDAMENTALS is a comprehensive text on the basic principles and practices of applied agricultural irrigation. Written over a period of more than 10 years, it is based on the authors'' extensive experience in farming, consulting, research, teaching, and other related agricultural activities. The book is for use by teachers of introductory courses in irrigation, farmers who have some basic technical knowledge, and for administrators who need a general understanding of irrigation as an aid for policy decisions in water resource development and planning. Various factors that influence crop yield and production including climate, fertility, water, drainage, and agronomic practices are addressed. The various irrigation methods such as border, basin, contour, furrow, sub, sprinkle, and drip or trickle are described; and conditions are given for selection of the appropriate method to use. Recent developments and new technology are included herein when they have obvious practical applications, but for the most part the material presented in this book is based on well established principles and practices. Much of the content is very practical and much is essentially nontechnical. Nevertheless, some of the material covered in this book goes beyond the basic concepts in an attempt to better describe the relationships and techniques employed by irrigation scientists and irrigation engineers.From the Preface: The future of the world depends very much on how we manage natural resources. Since the year 1900 there has been a ninefold increase in global carbon emissions from burning fossil fuels, and the world population has increased about 3.7 times in this century. Vast areas of forests have been destroyed, and irrigated lands now produce 40% of the food supply. Due to depletion of groundwater reserves and an increase in population, irrigated area per capita is declining. Consequently, the irrigation of additional alluvial lands is a strategic necessity for all of humankind. Much of the alluvial lands cannot be made productive without prior development of water resources through flood control, drainage, and irrigation. The production of electricity through hydropower and the production of alcohol fuel from irrigated crops, as has been practiced for many years in Brazil, can slow the increase in carbon emissions. Such diverse developments are typically not separable; rather, they must be considered as integral parts of a comprehensive development plan. The conservation of natural resources and increasing productivity of irrigated lands are also strategic necessities. Much of the current technology is highly transferable and crop yields can be significantly increased on lands already under irrigation.The authors have worked in many countries in connection with resource inventories, teaching, and the planning, development and use of irrigation as a tool for increasing production and providing employment. They have written extensively and have been honored for their achievements. They have considerable experience with everything from primitive low-technology irrigation developments to highly developed irrigation in the USA and in dozens of countries around the world. Both of the authors have dedicated their careers to teaching, research, and consulting in agricultural irrigation and water resources development and planning. It is their hope and expectation that this book will provide incentives for investigating and documenting land and water resources, improving development, increasing crop yields, conserving resources, and improving the environment.

Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates how literature, history and geographical analysis complement and enrich each other’s disciplinary endeavors. The Hun-Lenox Globe, constructed in 1510, contains the Latin phrase 'Hic sunt dracones' ('Here be dragons'), warning sailors of the dangers of drifting into uncharted waters. Nearly half a millennium earlier, the practice of ‘earth-writing’ (geographia) emerged from the cloisters of the great library of Alexandria, as a discipline blending the twin pursuits of Strabo’s poetic impression of places, and Herodotus’ chronicles of events and cultures. Eratosthenes, a librarian at Alexandria, and the mathematician Ptolemy employed geometry as another language with which to pursue ‘earth-writing’. From this ancient, East Mediterranean fount, the streams of literary perception, historical record and geographical analysis (phenomenological and Euclidean) found confluence. The aim of this collection is to recover such means and seek the fount of such rich waters, by exploring relations between historical geography, geographic information science (GIS) / geoscience, and textual analysis. The book discusses and illustrates current case studies, trends and discourses in European, American and Asian spheres, where historical geography is practiced in concert with human and physical applications of GIS (and the broader geosciences) and the analysis of text - broadly conceived as archival, literary, historical, cultural, climatic, scientific, digital, cinematic and media. Time as a multi-scaled concept (again, broadly conceived) is the pivot around which the interdisciplinary contributions to this volume revolve. In The Landscape of Time (2002) the historian John Lewis Gaddis posits: “What if we were to think of history as a kind of mapping?” He links the ancient practice of mapmaking with the three-part conception of time (past, present, and future). Gaddis presents the practices of cartography and historical narrative as attempts to manage infinitely complex subjects by imposing abstract grids to frame the phenomena being examined— longitude and latitude to frame landscapes and, occidental and oriental temporal scales to frame timescapes. Gaddis contends that if the past is a landscape and history is the way we represent it, then it follows that pattern recognition constitutes a primary form of human perception, one that can be parsed empirically, statistically and phenomenologically. In turn, this volume reasons that literary, historical, cartographical, scientific, mathematical, and counterfactual narratives create their own spatio-temporal frames of reference. Confluences between the poetic and the positivistic; the empirical and the impressionistic; the epic and the episodic; and the chronologic and the chorologic, can be identified and studied by integrating practices in historical geography, GIScience / geoscience and textual analysis. As a result, new perceptions and insights, facilitating further avenues of scholarship into uncharted waters emerge. The various ways in which geographical, historical and textual perspectives are hermeneutically woven together in this volume illuminates the different methods with which to explore terrae incognitaes of knowledge beyond the shores of their own separate disciplinary islands.

Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the breakdown in sustainabilityâ€"the capacity of the planet to provide quality of life now and in the futureâ€"that is signaled by disaster. The authors bring to light why land use and sustainability have been ignored in devising public policies to deal with natural hazards. They lay out a vision of sustainability, concrete suggestions for policy reform, and procedures for planning. The book chronicles the long evolution of land-use planning and identifies key components of sustainable planning for hazards. Stressing the importance of balance in land use, the authors offer principles and specific reforms for achieving their visions of sustainability.
