First published in 1988. There are many excellent texts on water supply and irrigation engineering, irrigation economics, agricultural development and the problems which often plague such efforts. Few syntheses of such writings have been made, despite a clear need for them from people interested in water resources and agricultural development: students of geography, economics, development studies and agricultural management, administrators, planners and aid agency staff. This book attempts...

An introduction to runoff agriculture - a form of agricultural irrigation - this text describes how the use of surface and subsurface water, often overlooked and wasted, enables both small farmers and commercial agriculturists to improve yields and the security of harvest, even in harsh and remote environments. The text introduces the techniques and strategies, as well as the challenges and the potential of the crucial approach, which can contribute so much to reducing land degradation and...

Global warming and changes in climate will have severe and lasting impacts on national efforts to alleviate poverty and promote sustainable development. Some of the world's poorest countries and communities are the most vulnerable and are already suffering the consequences. Yet often these countries are rich in natural capital, ecosystems, and biodiversity that can contribute to solutions as they can to climate change. Biodiversity is the foundation and mainstay of agriculture, forests, and f...

This document presents a summary of the first Status of the World's Soil Resources report, the goal of which is to make clear the essential connections between human well-being and the soil. The report provides a benchmark against which our collective progress to conserve this essential resource can be measured. The report synthesizes the work of some 200 soil scientists from 60 countries. It provides a global perspective on the current state of the soil, its role in providing ecosystem se...

The current literature compartmentalizes the complex issue of water and wastewater into its discrete components; technology, planning, policy, construction, economics, etc. Considered from the perspective of sustainability, however, water in the urban environment must be approached as a single resource that can be continuously reused and recycled. This book will be the first to capture all of the current work on this idea in a single, integrated, plan for designing the water-centric cities...

The search for cheap, plentiful and reliable energy has become one of the holy grails of modern industrial society. Since the Western technologically-advanced nations own supplies began to deplete from the 1970s those economies became increasingly dependent on foreign oil, especially from volatile (and potentially hostile) areas in the Middle East, and gas from the world’s major producer - Russia. The discovery of large deposits of shale oil and gas in North America and across other parts ...

By the year 2025 nearly 2 billion people will live in regions experiencing absolute water scarcity. In the face of this emerging crisis, how should the planet's water be used and managed? Current international policy sees nature competing with human uses of water. Hunt takes issue with this perspective. She suggests that nature is the source of water and only by making the conservation of nature an absolute priority will we have the water we need for human use in future. It is essential , ...

For decades now we have wasted and mismanaged the world?s water supplies. Today, 27 countries are short of water, a quarter of the world?s population has no safe water, 46 per cent have no proper sanitation and each year four million children die of water-borne diseases. As most of the world?s major river systems cross several national boundaries, the scope disputes and the threat to international security is becoming more and more real.In The Last Oasis, Sandra Postel examines the...

Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitab...

This book promotes better understanding and awareness of South Africa' significant water problems by describing the country's and especially the Upper Vaal River’s water resources. It is a “go-to” book for students, professionals and regular citizens when information is required regarding the country's and more specifically the Upper Vaal River’s freshwater resources. It highlights the major problems and risks which need to be addressed and give a realistic and true representation of the c...

The arid frontier has been a challenge for humanity from time immemorial. Drylands cover more than one-third of the global land surface, distributed over Africa, Asia, Australia, America and Southern Europe. Disasters may develop as a result of complex interactions between drought, desertification and society. Therefore, proactive planning and interactive management, including disaster-coping strategies, are essential in dealing with arid-frontier development.This book presents a co...
