Book Description
A beautifully detailed exploration of flora and fauna. Author Ron Larson offers a natural history of a Great Basin landscape that focuses on the northern region including Lake Abert and Abert Rim, and the adjacent area in southcentral Oregon. Although the jewel of this landscape is a lake, the real story is the many plants and animals—from the very primitive, reddish, bacteria-like archaea that thrive only in its high-salinity waters to the Golden Eagles and ravens that soar above the desert. The untold species in and around the lake are part of an ecosystem shaped by ageless processes from massive lava flows, repeated drought, and blinding snowstorms. It is an environment rich with biotic and physical interconnections going back millions of years. The Great Basin, and in particular the Lake Abert region, is special and needs our attention to ensure it remains that way. We must recognize the importance of water for Great Basin ecosystems and the need to manage it better, and we must acknowledge how rich the Great Basin is in natural history. Salt lakes, wherever they occur, are valuable and provide critically important habitat for migratory water birds, which are unfortunately under threat from upstream water diversions and climate change. Larson’s book will help people understand that the Great Basin is unique and that wise stewardship is necessary to keep it unspoiled. The book is an essential reference source, drawing together a wide range of materials that will appeal to general readers and researchers alike.

Book Description
This book establishes a framework for defining transboundary water cooperation and a methodology for evaluating its effectiveness, which will contribute to more effective and therefore successful cooperation processes. With the increasing focus on transboundary cooperation as a part of the Sustainable Development Goal Framework, there is global recognition of transboundary water cooperation as a tool for improved governance and management of transboundary surface and groundwaters. However, there is not an agreed upon definition of transboundary water cooperation in the literature or in practice. This book develops the Four Frames of Transboundary Water Cooperation, which is a neutral modular framework for developing context-specific explanatory definitions of transboundary water cooperation in basins and aquifers. The Four Frames of Cooperation are legal, institutional, relational, and outcome. However, we need to move beyond defining cooperation to understand better measures of the quality and effectiveness of cooperative processes. The Weighted Model of Effective Cooperation presents a first step in qualitatively evaluating the effectiveness of transboundary water cooperation. This model defines effective transboundary water cooperation and operationalizes a method to evaluate the effectiveness of cooperative processes over internationally shared waters. Effective cooperation emphasizes the relational and outcome frames of cooperation while working towards equitability and sustainability. Together, the Four Frames of Cooperation and the Weighted Model of Effective Cooperation will improve the understanding of cooperation and encourage a detailed evaluation of the quality, success, and effectiveness of cooperative processes. This book will be of great interest to students and scholars of water resource management, water governance, and environmental politics. It will also appeal to policymakers and professionals working in the fields of water conflict, water diplomacy, and international cooperation.

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
The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.

Book Description
The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.

Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.
