Available in PDF, EPUB and Kindle. Book excerpt: An engaging call to understand and protect groundwater, the primary source of drinking water for almost half of the world's population Groundwater is essential for drinking water and food security. It provides enormous environmental benefits by keeping streams and rivers flowing. But a growing global population, widespread use of industrial chemicals, and climate change threaten this vital resource. Groundwater depletion and contamination has spread from isolated areas to many countries throughout the world. In this accessible and timely book, hydrology expert William M. Alley and science writer Rosemarie Alley sound the call to protect groundwater. Drawing on examples from around the world, including case studies in the United States, Canada, Australia, India, and Sub-Saharan Africa, the authors examine groundwater from key scientific and socioeconomic perspectives. While addressing the serious nature of groundwater problems, the book includes stories of people who are making a difference in protecting this critical resource.

Available in PDF, EPUB and Kindle. Book excerpt: A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.
Download or read book Irrigation Fundamentals written by George H. Hargreaves and published by Water Resources Publication. This book was released on 1998 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020-12-22 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change poses serious threats to inclusive economic progress and poverty reduction. Strong countermeasures are required to increase the capacity of low-income people to mitigate their risk exposure to the impacts of climate change. Central pillars in planning for sustainable development and poverty alleviation must include vulnerability assessments, appropriate adaptation measures, and resilience-smart investments. This means placing climate change adaptation and resilience at the center of overall development policy. Coping with Climate Change in the Sundarbans contributes to this effort by synthesizing multiyear, multidisciplinary climate change studies on the Sundarbans—the world’s largest remaining contiguous mangrove forest and wetland of international importance, as well as home to some of South Asia’s poorest and most vulnerable communities. The studies’ findings indicate that, in a changing climate, sea-level rise, storm-surge intensification, and water salinization will alter the Sundarbans ecosystem significantly. The ripple effect of these changes will have multifaceted adverse impacts on the nature-dependent livelihoods, health, and nutrition of nearby communities. Elevated health risks, reduced land and labor productivity, and increased exposure to storms, floods, droughts, and other extreme events will make escape from poverty more difficult. Families in the Sundarbans are on the front line of these changes. Their experience and adaptation signal future decisions by hundreds of millions of families worldwide who will face similar threats from progressive sea-level rise. This research lays the technical foundation for developing a better understanding of the changes the Sundarbans currently faces, including responses of the ecosystem and human communities. Based on field research, location-specific, resilience-smart adaptation measures are recommended for reducing climate change vulnerability. Beyond the Sundarbans, the studies’ methods and findings will be of interest to development practitioners, policy makers, and researchers focused on island nations and countries worldwide that feature high-density populations and economic activity in low-lying coastal regions vulnerable to sea-level rise.
