Book Description
While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Book Description
Our nation's grandest enterprise is our agricultural industry. It is second to none in terms of assets, workers, and exports. Agricultural success has be come an accepted fact and is taken for granted by the majority of the American public. Few believe or are even willing to consider that the con tinued future success of this industry is threatened. Yet threatened it is. The resource base of agriculture is becoming dimin ished through overuse and environmental misuse. A further complication is the competition for agricultural resources by other users. The energy, soil, and water resources cannot sustain agriculture into the far future at their present rate of use. Something must be done to bring about public awareness and support for the changes needed to move our nation toward a sustainable agriculture. More research and funding must be directed toward this end. Our agriculture educators and other information disseminators must make sure that the farmers, politicians, and the public receive the message. Farmers must be willing to make the necessary changes. Something is being done. Our agricultural system is in a transitional stage. Traditional agriculturists are changing some practices and their attitudes.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
Arsenic Contamination in the World

Category : Science
ISBN : 1780400381
Book Description
Arsenic Contamination in the World: an International Sourcebook provides a global compendium of cited arsenic occurrences in the world as they affect public health. This book details arsenic contamination by source, region and arsenic-affected country. Arsenic is identified in 105 countries and territories, representing a larger database than any previous published work. Sources of arsenic contamination are categorized as Anthropogenic, Geogenic, Volcanogenic, Coal, Mining and Petroleum-related. National, regional and international maps locate the affected areas and populations. A synthesis of critical country information includes an estimate of the exposed population of 226 million people worldwide. This reference work is an indispensable tool for medical doctors, public health workers, scientists, water experts, governments, industries, non-profit organizations and communities in identifying site-specific arsenic contamination. An extensive bibliography of peer-reviewed literature gives the reader important arsenic contamination locations as the first step towards remediation. This Sourcebook is updatable via an on-line annex which provides up-to-date information on new arsenic occurrences and developments. We invite readers to participate in updating this database at: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/ExecutiveSummaryofArsenicContaminationintheWorld By synthesizing the known occurrences of arsenic world-wide, this reference book offers an essential tool for understanding and addressing the global arsenic geological-public health interface. Discounted ebook price available for customers from Developing Countries. Please contact [email protected] if you wish to purchase an ebook from a developing country @ £50.00 (PDF format).

Applied Manure and Nutrient Chemistry for Sustainable Agriculture and Environment

ISBN : 9401788073
Book Description
Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.
Landscape Heterogeneity and Disturbance

Release : 2012-12-06
Category : Science
ISBN : 146124742X
Book Description
Landscape pattern is generated by a variety of processes, including disturbances. In turn, the heterogeneity of the landscape may enhance or retard the spread of disturbance. The complex relationship between landscape pattern and disturbance is the subject of this book. It is designed to present an illustrative analysis of the topic, presenting the perspectives of several different disciplines. The book includes conceptual considerations, empirical studies, and management examples. Important features include: hypotheses about the spread of disturbance and the effects of scale changes in landscape studies; the multidisciplinary approach; and the explicit focus on the landscape level. The intended audience comprises graduate students, academics, and professionals interested in landscape ecology. The reader will receive a state-of-the-art treatment of a current topic in landscape ecology.
