Using a variety of case studies, this book provides an overview of how societies have gradually developed their water resources and furthers our understanding of how such resources can be managed successfully or unsuccessfully. Discussing how and why particular options are selected, and why a particular course of events eventually prevails, the book stresses the importance of context and a multidisciplinary approach in moving towards sustainable and equitable development.

The broad range of research topics reported in this abstract book is a valuable resource for researchers, advisors, teachers and professionals in agriculture. ICT in agriculture, the field of EFITA's interest, precision agriculture and precision livestock farming are becoming ever more relevant as the agricultural industry struggles to come to terms with various developments. These include issues of cooperation, Internet, standardisation, software architecture, robotics, environment, animal and human welfare, economics, traceability, farm management, vehicle guidance, crop management, animal disease and livestock management. Whilst some benefits have proved elusive, others contribute positively to today's agriculture. Research continues to be necessary and needs to be reported and disseminated to a wide audience. Also note that the reviewed papers from the 4th European Conference on Precision Livestock Farming and the 7th ECPA conference are presented in companion publications.

2009 reprint of the 1956 second edition. This title made available for the first time an adequately organized, comprehensive analytical method for evaluating the stresses, reactions and deflections in an irregular piping system in space, unlimited as to the character, location or number of concentrated loadings or restraints. Profusely illustrated and meticulously detailed.

A wider understanding of potato postharvest practices is needed to improve working relations between growers, agronomists, pathologists and crop store managers. Providing a comprehensive examination of international potato production, this book identifies which storage systems suit particular climatic zones, as well as considering interactions between crop microclimate, dehydration, crop cooling, condensation and disease development. "Potatoes Postharvest" will guide the reader through the activities following harvest from store loading, store management, and grading to packaging and dispatch.

One teacher's long journey to a kind of enlightenment.
"This is the best piece I've read on teaching in years. Not only does Guy nail issue after issue with laser-like precision, but he manages to afflict the comfortable and comfort the afflicted with humor and brief anecdotes, avoiding both the puffed-up academic pose and the grim earnestness of the wounded and the self-righteous. I really love it." Bill Ayers, Distinguished Professor of Education and author of "To Teach, The Journey of a Teacher," "Teaching Toward Freedom," and "Fugitive Days."

The author of this book has traveled extensively in many desert and semi-desert territories of the U.S.S.R., Morocco, Tunisia, the Egyptian region of the U.A.R., Pakistan and India where he realized the importance of water for the reclamation of vast areas of arid and semi-arid lands. During his visits the author became acquainted with the theory and practice of land irrigation in many countries of North Africa and Asia. The present book is the first attempt at generalizing the vast amount of material dealing with the hydrogeology of the irrigated lands of the arid zone of North Africa and Asia, stretching from the African coastline of the Atlantic Ocean to the central parts of Asia. Outlined in this book are the origin and distribution of saline lands in the deserts of North Africa, the Arabian Peninsula, the Iran Highlands, Middle Asia, China and Mongolia. A description is given of the surface waters in irrigated areas of the arid zone together with the sources, movement and draining, infiltration, condensation and evaporation of water in the desert and semi-desert territories. The book gives a sketch of the regime of free ground waters in irrigated areas and methods of studying it, problems of water balance and its forecasting, based on experimental research and simple theoretical calculations. Principles of the hydrogeological division of irrigated lands into districts and basic measures to prevent their salinization are also given. The book can serve as a textbook for engineer-hydrogeologists, melioration specialists and students at specialized hydrogeological and agricultural institutes and schools.

This is a Cisco approved lab companion for use within the Cisco Networking Academy Program CCNA 3 and 4 curriculum. This edition offers more coverage of cabling and VLSM than previous edition.

The overriding lesson from history is that most irrigation-based civilizations fail. As we enter the third millennium the question arises: Will ours be any different?

For 6,000 years, irrigation has ranked among the most powerful tools of human advancement. The story of settled agriculture, the growth of cities, and the rise of early empires is, to no small degree, a story of controlling water to make the land more prosperous and habitable. Pillar of Sand examines the history, challenges, and pitfalls of irrigated agriculture — from ancient Egypt and Mesopotamia to twentieth-century India and the United States. By unmasking the risks faced by irrigation-based societies — including water scarcity, soil salinization, and conflicts over rivers — water specialist Sandra Postel connects the lessons of the past with the challenge of making irrigation thrive into the twenty-first century and beyond.

Protecting rivers and vital ecosystems as the world aims to feed 8 billion people will require a doubling of water productivity — getting twice as much benefit from each gallon removed from rivers, lakes, and aquifers. Pillar of Sand points the way toward managing the growing competition for scarce water. And it lays out a strategy for correcting a startling flaw of the modern irrigation age — its failure to better the lives of the majority of the world's poorest farmers.
