Book Description
Richard Judd and Christopher Beach define the environmental imagination as the attempt to secure 'a sense of freedom, permanence, and authenticity through communion with nature.' The desire for this connection is based on ideals about nature, wilderness, and the livable landscape that are personal, variable, and often contradictory. Judd and Beach are interested in the public expression of these ideals in post-World War II environmental politics. Arguing that the best way to study the relationship between popular values and politics is through local and regional records, they focus on Maine and Oregon, states both rich in natural beauty and environmentalist traditions, but distinct in their postwar economic growth. Natural States reconstructs the environmental imagination from public commentary, legislative records, and other documents. Judd and Beach trace important divisions within the environmental movement, noting that they were balanced by a consistent, civic-minded vision of environmental goods shared by all. They demonstrate how tensions from competing ideals sustained the movement, contributed to its successes, but also limited its achievements. In the process, they offer insight into the character of the broader environmental movement as it emerged from the interplay of local, state, and national politics. The study ends in the 1970s when spectacular legislative achievements at the national level were masking a decline in mainstream civic engagement in state politics. The authors note the rise of the private ecotopia and the increasing complexity in the way Americans viewed their connections with the natural world. Yet, today, despite wide variations in beliefs and lifestyles, a majority of Americans still consider themselves to be environmentalists. In Natural States, environmental politics emerges less as a conflict between people who do and do not value nature, and more as a debate about the way people define and then chose to live with nature. In their attempt to place the passion for nature within a changing political and cultural context, Judd and Beach shed light on the ways that ideals unify and divide the environmental movement and act as the source of its enduring popularity.

Book Description
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.

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.
