This book focuses on the effects of four major uses of land on fresh waters above and below ground: agriculture, forestry, urbanisation, and the exploitation of minerals. It covers a wide range of issues, offering an exceptional breadth of coverage, and draws attention to all the major problems and their remedies, from scientific, technical, administrative and political viewpoints. The early sections, gathering experience from the UK, Italy and the Netherlands, describe sewerage and waste-water treatment of two new towns, motorway drainage quality control, and long-term contamination of aquifers below cities. In illustrating effects of mineral exploitation, further chapters range widely from the coal and china clay industries, to metalliferous mining. The discussion devoted to agriculture, regarded as needing most attention in the book, emantes from experts based in the European Economic Community, Hungary and the USA. It offers international experience on the problems caused to water by food production, as well as specific areas of pesticides and nitrates (including legislation), and acidification and gross organic pollution.
The section covering forestry, also written by international authorities, gives accounts of the results of wood production and processing on water yield and surface-water problems, and offers ecological and operational solutions to the difficulties. The work reflects an important meeting organised by the Water Research Centre and the World Health Organization, who jointly felt the need for this timely discussion on such international issues as the increased afforestation of the uplands, withdrawal from hill farming, increasing motorway networks, and the closure of coal mines. The book is a unique opportunity for key scientists in this field to record their successful methods for preventing and reducing problems, as well as warnings of how serious damage to the environment and to water resources can occur and go unnoticed for long periods of time.show more
