Using the latest mapping techniques, J.A.A. Jones, Chair of the IGU Commission for Water Sustainability, examines water availability, the impact of climate change and the problems created for water management worldwide as well as possible solutions. Water Sustainability: A Global Perspective is one of the first textbook to meld the physical and human aspects affecting the world's water resources. Part One outlines the challenges and investigates the human factors: population growth; urbanization and pollution; the commercialization of water, including globalization and privatization; and the impacts of war, terrorism and the credit crunch. Part Two examines the physical aspects: the restless water cycle, the impact of past and future climate change and the problems change and unreliability create for water management. Part Three discusses current and future solutions including improved efficiency and water treatment systems, desalination, weather modification and rainwater harvesting, and improved legal and administrative frameworks. Jones concludes by asking how far technical and financial innovations can overcome the limitations of climatic resources and examining the human and environmental costs involved in such developments. This book is the ideal text for any student of water sustainability whether approaching the subject from the point of view of international relations, geography or environmental management.
An infographic introduction to Earth's most important resource.
This topic is central to contemporary concerns for more sustainable agricultural development. This is a well-written and clear book, with excellent data, tables and illustrations, addressing issues of water use, climate change, poverty and small farmers. The authors are highly respected and complement each other's acknowledged international expertise.' Professor Jules Pretty, University of Essex, UK 'This useful guide shows that there is great potential for increasing the productive capacity of smallholder farms in the drylands via a range of water management techniques, from the simple to the more complex. Providing a theoretical grounding and a practical guide, Water and cereals in the drylands will appeal to workers on-location as well as students, researchers and policymakers.' New Agriculturalist Cereals are by far the most important source of food throughout the world, either directly for human consumption or indirectly in the form of animal feed for livestock products consumed as food. With world population set to rise to nine billion by 2050, there is an urgent need to examine ways to increase cereal production. Indeed recently the future of cereal production and consumption has been complicated by rising energy prices and the economics of biofuels, which are competing for the use of cereals. One way to increase cereal production is by the more effective use of marginal dryland areas. This book reviews the potential for increased cereal production in drylands across the world, from the USA, Australia and Southern Europe to Asia and Africa. It describes how improved water conservation, water harvesting and investment options can contribute to this, and suggests policies for the more efficient use of existing natural resources in order to lessen the dependence of agriculture on further irrigation development.
During the second half of the nineteenth century the enormous increase in agricultural production, unmatched by technical advance in harvesting, drew vast numbers of rural and migrant workers into the harvest that lasted from June to October.
This book, first published in 1982, examines the technology, conditions and customs of the harvest and, through that, the life of the rural population of central England from the 1840s until the end of the century when hand tools finally gave way to mechanisation.
The economic framework of the period in agriculture is set out and there flows a detailed analysis of hand tools and work methods in the harvest. The population of harvesters, agricultural labourers and their entire families, townspeople and the gangs of migrant workers are studied, as are the crops they harvested.
How can the Earth s finite water resources be managed sustainably to meet the growing needs of humans and of nature in ways that avert the looming crisis? The need to find answers to this question has exercised the minds of many scientists, practitioners and policymakers who recognise the urgency of the problems. These concerns have spawned a number of international research initiatives and programs, prominent representatives of which met to review progress and exchange views at an international conference in Bonn, Germany in February 2005.
The pressing water problems must clearly be tackled from an integrated perspective taking into account environmental, human and technological factors and especially their interdependence. The key papers in this volume from the Bonn conference focus on the challenges of integrated assessment of water resources in the context of global change. The growing gap between North and South is also addressed, in terms not only of access to water and its quality, but also of the capacity to do research and implement solutions.
The coverage of the papers is up-to-date and comprehensive. Highlights include emerging concepts such as blue and green water, virtual water, the water footprints of nations, multi-agent modelling, linkages between water and biodiversity, and social learning and adaptive management."
