Book Description
This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.

Book Description
Jan Morris's magnificent book celebrates Wales and all things Welsh. Written as a deeply personal study, it reflects the rich bilingual literature and folklore of Wales, the buildings and wonderfully varied landscapes, the national character and humour, the historical predicaments and the political condition of this small but extraordinary country. Jan Morris is a distinguished historian as well as being one of the world's leading travel-writers. Her passionate love of Wales makes this a unique evocation.

Book Description
Based on extensive research, The Naval History of Wales tells a compelling story that spans nearly 2,000 years, from the Romans to the present. Many Welsh men and women have served in the Royal Navy and the navies of other countries. Welshmen played major parts in voyages of exploration, in the navy's suppression of the slave trade, and in naval warfare from the Viking era to the Spanish Armada, in the American Civil War, both world wars and the Falklands War. Comprehensive, enlightening, and provocative, The Naval History of Wales also explodes many myths about Welsh history, naval historian J.D. Davies arguing that most Welshmen in the sailing navy were volunteers and that, relative to the size of national populations, proportionately more Welsh seamen than English fought at Trafalgar. Written in vivid detail, this volume is one that no maritime or Welsh historian can do without.

Book Description
As people crowded into British cities in the nineteenth century, industrial and biological waste byproducts and then epidemic followed them. Britons died by the thousands in recurring plagues. Figures like Edwin Chadwick and John Snow pleaded for measures that could save lives and preserve the social fabric. The solution that prevailed was the novel idea that British towns must build public water supplies, replacing private companies. But the idea was not an obvious or inevitable one. Those who promoted new waterworks argued that they could use water to realize a new kind of British society—a productive social machine, a new moral community, and a modern civilization. They did not merely cite the dangers of epidemic or scarcity. Despite many debates and conflicts, this vision won out—in town after town, from Birmingham to Liverpool to Edinburgh, authorities gained new powers to execute municipal water systems. But in London local government responded to environmental pressures with a plan intended to help remake the metropolis into a collectivist society. The Conservative national government, in turn, sought to impose a water administration over the region that would achieve its own competing political and social goals. The contestants over London's water supply matched divergent strategies for administering London's water with contending visions of modern society. And the matter was never pedestrian. The struggle over these visions was joined by some of the most colorful figures of the late Victorian period, including John Burns, Lord Salisbury, Bernard Shaw, and Sidney and Beatrice Webb. As Broich demonstrates, the debate over how to supply London with water came to a head when the climate itself forced the endgame near the end of the nineteenth century. At that decisive moment, the Conservative party succeeded in dictating the relationship between water, power, and society in London for many decades to come.

Book Description
The Marine Bill was designed to establish a new UK-wide strategic system of marine planning to balance conservation, energy and resource needs, based on the principle of sustainable development and working with the devolved administrations. The Committee reports here reservations about the framework nature of the draft Bill. It was felt that too much of its policy is contained in secondary legislation or guidance. That there are significant areas of confusion of responsibility - between UK and international, especially EU, obligations; between devolved administrations; the many agencies and other bodies who will be involved in delivering the proposals in the Bill.

Book Description
REGIONAL WATER SECURITY Regional Water Security provides new research on policy innovations that promote the application of demand management and green infrastructure (GI) in managing water resources across regions sustainably. In particular, with regional water security around the world at risk from climatic and non-climatic challenges impacting water quantity and water quality, this book, in addition to providing examples of demand management and GI being implemented in various locations globally, contains in-depth case studies that illustrate how regions, of differing climates, lifestyles, and income levels, have implemented policy innovations that promote the application of demand management and GI to achieve regional water security for humans while protecting and restoring the natural environment. Regional Water Security will be of interest to regional water resource managers, town and regional planners, resource conservation managers, policymakers, international companies, and organizations as well as environmental NGOs, researchers, and graduate and undergraduate students.

Book Description
This book is about how water becomes people – or, put another way, how people and water flow together and shape each other. While the focus of the book is on the relationships held between water and people, it also has a broader message about human relationships with the environment generally – a message that illustrates not only that people are existentially entangled with the material world, but that the materials of the world shape, determine and enable humans to be ‘humans’ in the ways that they are. Offering a selection of anthropological examples from Kenya, Wales and Spain to illustrate how water’s materiality coproductively generates the way people are able to engage with water, this book uses cross-disciplinary perspectives to provide and promote a new analytic – one that encourages ethical, holistic and sustainable relationships with the world around us. This approach challenges representations that ignore, sidestep or are blind to the fleshy materiality of being human, and aims to encourage a re-imagining of the world that acknowledges humanity as intrinsically active-with and part of the fabric of the collection of materials we call planet Earth.
