Download or read book Irrigation Fundamentals written by George H. Hargreaves and published by Water Resources Publication. This book was released on 1998 with total page 202 pages. 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.

Download or read book Africana Critical Theory written by Reiland Rabaka and published by Lexington Books. This book was released on 2009 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building on and going far beyond W.E.B. Du Bois and the Problems of the Twenty-First Century and Du Bois's Dialectics, Reiland Rabaka's Africana Critical Theory innovatively identifies and analyzes continental and diasporan African contributions to classical and contemporary critical theory. This book represents a climatic critical theoretical clincher that cogently demonstrates how Du Bois's rarely discussed dialectical thought, interdisciplinarity, intellectual history-making radical political activism, and world-historical multiple liberation movement leadership helped to inaugurate a distinct Africana tradition of critical theory. With chapters on W.E.B. Du Bois, C.L.R. James, Negritude (Aime Cesaire and Leopold Senghor), Frantz Fanon and Amilcar Cabral, Africana Critical Theory endeavors to accessibly offer contemporary critical theorists an intellectual archaeology of the Africana tradition of critical theory and a much-needed dialectical deconstruction and reconstruction of black radical politics. These six seminal figures' collective thought and texts clearly cuts across several disciplines and, therefore, closes the chasm between Africana Studies and critical theory, constantly demanding that intellectuals not simply think deep thoughts, develop new theories, and theoretically support radical politics, but be and constantly become political activists, social organizers and cultural workers - that is, folk the Italian critical theorist Antonio Gramsci referred to as 'organic intellectuals.' In this sense, then, the series of studies gathered in Africana Critical Theory contribute not only to African Studies, African American Studies, Caribbean Studies, Cultural Studies, Gender Studies, and Postcolonial Studies, but also to contemporary critical theoretical discourse across an amazingly wide-range of 'traditional' disciplines, and radical political activism outside of (and, in many instances, absolutely against) Europe's ivory towers and the absurdities of the American academy.

Download or read book Coastal Wetlands Alteration and Remediation written by Charles W. Finkl and published by Springer. This book was released on 2017-07-18 with total page 879 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delves into human-induced and natural impacts on coastal wetlands, intended or otherwise, through a series of vignettes that elucidate the environmental insults and efforts at amelioration and remediation. The alteration, and subsequent restoration, of wetland habitats remain key issues among coastal scientists. These topics are introduced through case studies and pilot programs that are designed to better understand the best practices of trying to save what is left of these fragile ecosystems. Local approaches, as well as national and international efforts to restore the functionality of marsh systems are summarily approached and evaluated by their efficacy in producing resilient reclamations in terms of climate-smart habitat conservation. The outlook of this work is global in extent and local by intent. Included here in summarized form are professional opinions of experts in the field that investigate the crux of the matter, which proves to be human pressure on coastal wetland environments. Even though conservation and preservation of these delicate environmental systems may be coming at a later date, many multi-pronged approaches show promise through advances in education, litigation, and engineering to achieve sustainable coastal systems. The examples in this book are not only of interest to those working exclusively with coastal wetlands, but also to those working to protect the surrounding coastal areas of all types.
Download or read book Unlikely Alliances written by Zoltán Grossman and published by University of Washington Press. This book was released on 2017-06-20 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Often when Native nations assert their treaty rights and sovereignty, they are confronted with a backlash from their neighbors, who are fearful of losing control of the natural resources. Yet, when both groups are faced with an outside threat to their common environment—such as mines, dams, or an oil pipeline—these communities have unexpectedly joined together to protect the resources. Some regions of the United States with the most intense conflicts were transformed into areas with the deepest cooperation between tribes and local farmers, ranchers, and fishers to defend sacred land and water. Unlikely Alliances explores this evolution from conflict to cooperation through place-based case studies in the Pacific Northwest, Great Basin, Northern Plains, and Great Lakes regions during the 1970s through the 2010s. These case studies suggest that a deep love of place can begin to overcome even the bitterest divides.

Download or read book Historical Geography GIScience and Textual Analysis written by Charles Travis and published by Springer Nature. This book was released on 2020-02-29 with total page 281 pages. 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.
