This report on Water Quality and Agriculture examines the linkages between agriculture and water quality. It discusses the overall trends and outlook for agriculture and water quality in OECD countries; describes recent actions by policy makers to address water quality issues in agriculture; and provides a set of recommendations for countries to meet the challenge of improving agricultural water quality.

This book gives a comprehensive presentation of our present understanding of the Earth's Hydrological cycle and the problems, consequences and impacts that go with this topic. Water is a central component in the Earth's system. It is indispensable for life on Earth in its present form and influences virtually every aspect of our planet's life support system. On relatively short time scales, atmospheric water vapor interacts with the atmospheric circulation and is crucial in forming the Earth's climate zones. Water vapor is the most powerful of the greenhouse gases and serves to enhance the tropospheric temperature. The dominant part of available water on Earth resides in the oceans. Parts are locked up in the land ice on Greenland and Antarctica and a smaller part is estimated to exist as groundwater. If all the ice over the land and all the glaciers were to melt, the sea level would rise by some 80 m. In comparison, the total amount of water vapor in the atmosphere is small; it amounts to ~ 25 kg/m2, or the equivalent of 25 mm water for each column of air. Yet atmospheric water vapor is crucial for the Earth’s energy balance. The book gives an up to date presentation of the present knowledge.

Minnesota has a unique role in U.S. water policy. Hydrologically, it is a state with more than 12,000 lakes, an inland sea, and the headwaters of three major river systems: the St Lawrence, the Red River of the North, and the Mississippi. Institutionally, Minnesota is also unique. All U.S. states use Total Maximum Daily Load (TMDL) approaches to addressing impaired waters. Every TMDL requires a substantial investment of resources, including data collection, modeling, stakeholder input and analysis, a watershed management plan, as well as process and impact monitoring. Minnesota is the only state in the union that has passed legislation (the 2007 Clean Water Legacy Act) providing significant resources to support the TMDL process. The book will be an excellent guide for policymakers and decision makers who are interested in learning about alternative approaches to water management. Non-governmental organizations interested in stimulating effective water quality policy will also find this a helpful resource. Finally, there are similarities between the lessons learned in Minnesota and the goals of water policy in several other states and nations, where there are competing uses of water for households, agriculture, recreation, and navigation.

In the continental United States, rivers serve to connect state to state, interior with exterior, the past to the present, but they also divide places and peoples from one another. These connections and divisions have given rise to a diverse body of literature that explores American nature, ranging from travel accounts of seventeenth-century Puritan colonists to magazine articles by twenty-first-century enthusiasts of extreme sports. Using pivotal American writings to determine both what literature can tell us about rivers and, conversely, how rivers help us think about the nature of literature, The Meaning of Rivers introduces readers to the rich world of flowing water and some of the different ways in which American writers have used rivers to understand the world through which these waters flow. Embracing a hybrid, essayistic form—part literary theory, part cultural history, and part fieldwork—The Meaning of Rivers connects the humanities to other disciplines and scholarly work to the land. Whether developing a theory of palindromes or reading works of American literature as varied as Henry David Thoreau's A Week on the Concord and Merrimack Rivers and James Dickey’s Deliverance, McMillin urges readers toward a transcendental retracing of their own interpretive encounters. The nature of texts and the nature of “nature” require diverse and versatile interpretation; interpretation requires not only depth and concentration but also imaginative thinking, broad-mindedness, and engaged connection-making. By taking us upstream as well as down, McMillin draws attention to the potential of rivers for improving our sense of place and time.
