Download or read book Enriching the Earth written by Vaclav Smil and published by MIT Press. This book was released on 2004-02-27 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.

Download or read book Eutrophication causes consequences and control written by Abid A. Ansari and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Download or read book Oxygen Dynamics in the Chesapeake Bay written by David E. Smith and published by Schiffer Publishing. This book was released on 1992 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the processes that create and sustain anoxia (the absence of oxygen) and hypoxia (the near absence of oxygen) in bottom waters of the Chesapeake Bay. The authors of the book's four chapters discuss major findings and summarize the gradually developing consensus on the implications of these findings for resource management. William C. Boicourt focuses on the physical aspects of Chesapeake Bay in order to distinguish the role and relative importance of circulation processes in the creation of low dissolved oxygen levels. Thomas C. Malone examines the role of water column processes, including the importance and interaction of nutrients, phytoplankton and zooplankton. Robert Jonas discusses the significance of microbial populations, while W. Michael Kemp and Walter R. Boynton discuss the role and importance of benthicpelagic coupling on Chesapeake Bay dissolved oxygen.

Book excerpt: This reference work analyzes and assesses global environmental management techniques for environmental materials with a focus on their performance and economic benefits, proposing eco-friendly solutions and designating policies that will sustain the environment for future generations. It addresses management of environmental materials as not only a complex anthropogenic problem, but also as an expensive problem that needs to be managed sustainably. Simultaneously, it considers the environmental and economic benefits involved in the high levels of investment and operation costs required to develop effective materials collection and management systems in modern society.
