Book Description
Drylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources. Originally published in 19990

Book Description
This document is Alberta's first report on the state of its environment. The report first describes the population, economy, and natural regions of Alberta, then describes the present condition of the environment, the impact of human and natural activities on the environment, and actions or management responses under way to protect, enhance, and restore the environment. This information is presented in sections covering the atmosphere, surface and ground water, forested and agricultural land, mineral resources, wetlands, protected areas, waste management, and biota. A glossary is included, as well as appendices on the natural regions of Alberta and information on threatened or endangered species. Throughout the report are graphs and tables of statistics on various aspects of the Alberta environment.

Book Description
Land and Stream Salinity is a compilation of papers that review the state and knowledge of processes involved in land and stream salinity, and that consider its application in different environments. This book also identifies gaps in research and development, and it designates the priorities that could significantly benefit salinity control. In addition, it identifies alternative strategies of land and water management for salinity control and determines techniques for evaluating quantitatively the alternative strategies. Furthermore, this book focuses on salinity problems in south Western Australia. After discussing the history and effects of salinity in Western Australia, the book considers the influence of plant communities on the hydrology of catchments, and it discusses evapotranspiration rates from wet and dry foliage and soil water deficit. This is followed by the transport of salts in soils and subsoils; the residence times of water and solutes within and below the root zone and saturated zone; analyses of solute distributions in deeply weathered soils; and the transport of salts in catchments and soils. This book also includes chapters on the saline seed development and control in the North American Great Plains, and the terrain, groundwater and secondary salinity in Victoria, Australia. It also presents the hydrologic model, the solute-transport models and their role in the analysis of groundwater, and the hydrosalinity models. The last chapters focus on different kinds of management for salinity control.
