Book Description
Speaking for the River is the first book-length study of Willamette River clean-up efforts from the 1920s through the 1970s. These efforts centered on a struggle between abatement advocates and the two primary polluters in the watershed, the City of Portland and the pulp and paper industry.

Book Description
"The management of public lands in the West is a matter of long-standing and oft-contentious debates. The government must balance the interests of a variety of stakeholders, including extractive industries like oil and timber; farmers, ranchers, and fishers; Native Americans; tourists; and environmentalists. Local, state, and government policies and approaches change according to the vagaries of scientific knowledge, the American and global economies, and political administrations. Occasionally, debates over public land usage erupt into major incidents, as with the armed occupation of Malheur National Wildlife Refuge in 2016. While a number of scholars work on the politics and policy of public land management, there has been no central book on the topic since the publication of Charles Davis's Western Public Lands and Environmental Politics (Westview, 2001). In The Environmental Politics and Policy of Western Public Lands, Erika Allen Wolters and Brent Steel have assembled a stellar cast of scholars to consider long-standing issues and topics such as endangered species, land use, and water management while addressing more recent challenges to western public lands like renewable energy siting, fracking, Native American sovereignty, and land use rebellions. Chapters also address the impact of climate change on policy dimensions and scope. The Environmental Politics and Policy of Western Public Lands is co-published with Oregon State University Open Educational Resources, who will release an open access edition alongside this print edition"--

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
Despite significant progress in water and sanitation much still remains to be done. This report shows how the world has changed since 1990. It provides an assessment of progress towards the MDG target and insight into the remaining challenges. Section A provides an overview of progress against the parameters specified in the MDG target for water and sanitation in both urban and rural areas. It presents data for the world as a whole and compares progress across regions. The report goes on to examine trends over the MDG period by region and by level of service. It pays particular attention to the numbers of people who have gained the highest level of service in drinking water supply - piped water on premises - and those with no service at all who use surface water for drinking and practice open defecation. In order to understand the nature of progress it is important to look carefully at the way improvements in water and sanitation have benefited different socioeconomic groups. This report sheds light on equality gaps between urban and rural dwellers and between the richest and poorest segments of the population. It presents several new ways to visualize progress on extending service to the poor designed to reveal the nature of inequalities and give the reader insight into the great challenge that still exists in ensuring that progress reaches everyone. The JMP was established in 1990 and is celebrating its Jubilee Year in 2015. Section B provides a retrospective analysis of the evolution of water sanitation and hygiene monitoring over the past 25 years.
