Book SynopsisRemote Sensing Technology in Forensic Investigations provides a basic understanding of concepts involved in the use of basic geophysical surveying, metal detectors, magnetics, electromagnetics and ground penetrating radar in police and forensic investigations. Such technology can be vital in locating clandestine, buried evidence which is often concealed in the subsurface underground. Crime scene investigation and evidence collection entails locating, identifying, collecting, and cataloging. Such physical evidence searches are time consuming and can often lead to searches that require excavations, which in itself that can destroy evidence. The noninvasive, nondestructive methods outlined in this book can both reduce the time spent on searches and excavations, thereby increasing the probability of locating vital physical evidence. As such, the application of remote sensing methods has gained increased acceptance, and seen increased usage, by investigators.RemotTable of ContentsIntroduction.

Book SynopsisLand is a finite resource and is the basis for 90 per cent of all human food, livestock feed, fibre, and fuel - and we are running out of it. Even worse, large amounts are degraded with only a third showing no signs of degradation, and a quarter being severely or very severely degraded. The economic implications of land degradation are vast and closer investigation of the costs involved in remediating degraded and contaminated industrial wasteland may reveal significantly higher costs, especially since large areas of industrial degradation have not yet been assessed. This book addresses the fundamental science and engineering of land degradation and rehabilitation from a multi-disciplinary perspective. The first part of the book discusses natural ground profiles dealing with soil science and the underlying geology, the functions of natural ground and ground engineering properties. In the second part, three basic mechanisms of ground degradation are introduced: erosion, chemical degradation and physical degradation. The third part addresses remediation, including strategies and techniques to investigate the ground and remediation measures.Finally, issues of land protection are outlined and a general strategy of sustainable land management are discussed. With a firm basis in soil science and allied subjects, this book provides an eminently readable and thoughtful introduction for anyone in the area of land remediation, whether as a professional seeking an overview or a student requiring a broad perspective.Trade Review'... a good point where to start and a sounding bell for those who are or will be in the position to act directly on the land.

Book SynopsisDevelopments in the modelling of sediment transport in rivers and the interactions with the river-bed have been remarkable over the last two decades. This progress has increased the understanding of the nature of turbulence, and the ability to replicate mathematically simple flow-particle interactions which can be observed experimentally. In addition, quite elegant models of stratigraphic complexes have evolved because of the growing computational power available to scientists. As always, additional knowledge has raised even more intriguing questions and the quest for explanation of phenomena has led to increased specialisation. Therefore, there are few fluid dynamicists or sedimentologists who can successfully span the two disciplines. The intention of this book is to assist various specialists on keeping abreast of current developments in related areas.

Book SynopsisAcid deposition is considered to be one of the greatest threats to the environment in industrialised countries. Recognising this , governments have instituted programmes to reduce emissions of SO2, and NOx, the major sources of acid rain. But is this enough? Will ecosystems damaged by acid rain recover? And if they do, how quickly? What ecosystem processes determine the rate of recovery? Do acidification models give accurate predictions? Are any other actions necessary to promote recovery? To answer such questions without waiting for the results of current policies, scientists in Sweden and the UK decided to eliminate acid deposition on an acidified ecosystem altogether, and monitor the effects. They did this by constructing a huge roof over an acidified catchment near Lake G?rdsjon in Southwest Sweden. Acid rain falling on the roof is diverted away, and replaced with clean rain. The detailed responses of the ecosystem are measured.

Book SynopsisThe discipline of Stochastic Processes is usually treated as a branch of mathematics, and there are plenty of books for mathematicians on the subject. Equally, there are very many books, both for statisticians and environmental scientists, on Time Series Analysis, analysing the structure of data sequences where measurements are made at equal time-intervals and are free from intermittent behaviour. But this book deals with the analysis of events which occur intermittently in time and space; through a very wide range of examples drawn from many areas of environmental science in which the role of water is central, the book shows how the same analytical procedures can be applied to very many different problems. The book s many examples include: analysis of time intervals between el Ni?o events, frequency of dry spells, the relation between heavy rainfall and flooding, occurrences of gravel disturbance in upland trout streams which damages trout spawn deposits and the cellular structure of Table of ContentsModels: Deterministic, Time Series and Stochastic.

Book SynopsisEstuaries is a comprehensive introductory text emphasizing the physical processes involved in the mixing of sea and river water and the transport of fine sediments within the complex estuarine topographic context. The theoretical and mathematical formulation of these processes are treated at a fairly elementary level, and are used to develop a foundation for more extensive study. The second edition retains the classical approaches to the tidally averaged circulation and mixing conditions but broadens them to consider recent advances in the understanding of processes occurring within the tide. The scope has also been widened to include more detail on the morphology of estuaries and their development, the fluxes of suspended fine sediments, and the generation and maintenance of turbidity maximum. The book provides an excellent introduction for research students in oceanography, environmental science, geography, geology, and water and coastal engineering.

Book SynopsisThis book provides a comprehensive overview of grassland nitrogen incorporating information from crop science, soils and fertilizers, ruminant consumption and environmental aspects. The published information is reviewed on the various transformations of nitrogen in temperate grassland systems. These include those taking place in soils. The effects of soil, weather and management practices are discussed and considerable emphasis is placed on soil-plant-animal interactions. A second aim of the book is to describe the factors that influence the response of grassland to the application of fertilizer nitrogen, and how the optimum rate of application may be determined. In addition, nitrogen balances are described for different grassland systems, showing how the annual inputs and outputs vary greatly depending on sward type and management.

Book SynopsisBiological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems.

Book SynopsisPhosphorus is an essential element for plant growth and its input has long been recognised as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologTable of Contents1: Contributors 2: Preface 3: Acknowledgements 4: Phosphorus in Agriculture and Its Environmental Implications, A Sharpley and S Rekolainen 6: Estimating the Contribution from Agriculture to the Phosphorus Load in Surface Water , S D Lennox, R H Foy, R V Smith and C Jordan 7: Phosphorus Losses from Agriculture to Surface Waters in the Nordic Countries S Rekolainen, P Ekholm, B Ulén and A Gustafson 8: Reconstructing Historical Phosphorus Concentrations in Rural Lakes Using Diatom Models N J Anderson 9: The Dynamics of Phosphorus in Freshwater and Marine Environments, C E Gibson 10: The Behaviour of Soil and Fertilizer Phosphorus, M A Morgan 11: Setting and Justifying Upper Critical Limits for Phosphorus in Soils, E Sibbesen and A N Sharpley 12: Phosphorus Fertilizer Strategies: Present and Future, H Tunney, A Breeuwsma, P Withers and P Ehlert 13: Sources and Pathways of Phosphorus Loss from Agriculture, A L Heathwaite 14: Hydrological and Chemical Controls on Phosphorus Loss from Catchments H P Pionke, W J Gburek, A N Sharpley and J A Zollweg 15: Movement of Phosphorus from Agricultural Soil to Water, B Pommel and J M Dorioz 16: Losses of Phosphorus in Drainage Water, P C Brookes, G Heckrath, J De Smet, G Hofman and J Vanderdeelen 17: Sustainable Phosphorus Management in Agriculture, G Bertilsson and C Forsberg 18: Phosphorus Requirements for Animal Production, P B Lynch and P J Caffrey 19: Nutrient Management Planning, T C Daniel, O T Carton and W L Magette 20: A European Fertilizer Industry View on Phosphorus Retention and Loss from Agricultural Soils, I Steén 21: European Perspective on Phosphorus and Agriculture, F Mariën 22: Views on Phosphorus and Agriculture - Paris Commission, S Sadowski 23: Phosphorus Loss in Runoff, Leaching and Erosion, Poster Chapter 24: Catchment Studies, Modelling and Management, Poster Chapter 25: Phosphorus Status of Soils and Fertilizer Recommendations, Poster Chapter 26: Phosphorus Loss from Agriculture to Water: Synthesis and Summary, A E Johnston, H Tunney and R H Foy 27: Index

Book SynopsisAgroforestry refers to land use systems in which trees or shrubs are grown in association with agricultural crops, or pastures and livestock. From its inception, it has contained a strong element of soil management. Well-designed and managed agroforestry systems have the potential to control run-off and erosion, maintain soil organic matter and physical properties, and promote nutrient cycling. By these means, agroforestry can make a major contribution to sustainable land use. The previous edition of this book, entitled Agroforestry for Soil Conservation (1989), was based on indirect evidence from agriculture, forestry and soil science. The present work provides a new synthesis, drawing on over 700 published sources dating largely from the 1990s. These include both results of field trials of agronomy systems, and research into the plant-soil processes which take place within them. Soil conservation in its narrower sense, the control of erosion, is treated alongside other equally importTable of Contents1: Preface 2: Agroforestry, soil management and sustainability 3: Effects of trees on soils 4: Soil and water conservation 5: Soil water management 6: Soil organic matter and physical properties 7: Nutrient cycling and nutrient use efficiency 8: The role of roots 9: Agroforestry systems for soil management 10: Modelling 11: Research 12: Agroforestry, land use and the environment 13: Conclusions

Book SynopsisPlant species which can accumulate high concentrations of heavy metals have been known for over one hundred years. However, until the last twenty years their potential went largely unnoticed by scientists. The term hyperaccumulation was first introduced by the author (and colleagues) in 1977. This renewed interest, together with heightened environmental awareness and the discovery of the phenomenon in many more species has since stimulated research into a number of novel scientific and commercial uses. This book brings together for the first time in one volume all the relevant ecological information on hyperaccumulators and describes the new disciplines, methods and uses for them which continue to be explored. These include the removal of heavy metal pollutants from soils and waters (phytoremediation), the identification of ancient human settlements (phytoarchaeology), mineral exploration, the revegetation of degraded land and the exciting possibility of the commercial extraction of heTable of Contents1: General Introduction, R R Brooks 2: Phytochemistry of Hyperaccumulators, R R Brooks 3: Geobotany and Hyperaccumulators, R R Brooks 4: Biogeochemistry and Hyperaccumulators, R R Brooks 5: Seaweeds as Hyperaccumulators, C E Dunn, Geological Survey of Canada, Ottawa, Canada 6: Hyperaccumulation of Metals by Prokaryotic Microorganisms Including the Blue-Green Algae (Cyanobacteria), T J Beveridge, College of Biological Science, University of Guelph, Canada 7: Phytoarchaeology and Hyperaccumulators, R R Brooks 8: Hyperaccumulation as a Plant Defensive Strategy, R S Boyd, Auburn University, USA 9: Aquatic Phytoremediation by Accumulator Plants, R R Brooks and B H Robinson, Massey University, New Zealand 10: Revegetation and Stabilisation of Mine Dumps and Other Degraded Terrain,R R Brooks, A Chiarucci, Università degli Studi di Siena, Siena, Italy and T Jaffré, ORSTOM, Nouméa, New Caledonia 11: Fertilisation of Hyperaccumulators to enhance their Potential for Phytoremediation and Phytomining, F A Bennett, E K Tyler, R R Brooks, P E H Gregg, and R B Stewart, Massey University, New Zealand 12: Phytoextraction for Soil Remediation, S P McGrath, IACR-Rothamsted, Harpenden, UK 13: Phytoremediation by Volatilisation, R R Brooks 14: A Pioneering Study of the Potential of Phytomining for Nickel, L J Nicks, Retired Researcher, Fernley, USA and M F Chambers, Retired Researcher, Reno, USA 15: The Potential Use of Hyperaccumulators and Other Plants for Phytomining, R R Brooks and B H Robinson, Massey University, New Zealand"

Book SynopsisApproaches to research on the causes and impacts of soil erosion have changed significantly over recent years. Whereas biophysical research traditionally utilized small, carefully-managed erosion plots, models and methods are now available to study impacts of broad scale management on the hydrology and water quality of catchments and even river basins. Corresponding research tools have been developed for social and economic analysis at the household, farm and community levels. This book reviews the latest developments in such soil erosion studies. These are considered on a matrix of scales, from plot to river basin, and from farm to national policy. Some chapters review background issues while others consider specific methods. Conclusions of working groups are presented in another chapter. The book is based on papers presented at a workshop held in Indonesia in November 1997, and includes authors from Europe, America, Australia and Asia, as well as from several of the CGIAR centres.Table of Contents1: A Framework for the Economic Assessment of Soil Erosion and Soil Conservation 2: The Economics of Soil Degradation: From National Policy to Farmers' Fields 3: Bioeconomic Modelling for Analysing Soils Conservation Policy Issues 4: A Multiscale Approach for On-farm Erosion Research: Application to Northern Thailand Highlands 5: Building the Smallholder into Successful Natural Resource Management at the Watershed Scale 6: A Microeconomic Analysis of Adoption of Contour Hedgerows in the Philippine Uplands 7: Investigating Constraints to the Adoption of Recommended Soil Conservation Technology in the Philippines 8: CIAT's Strategic Research for Sustainable Land Management on the Steep Hillsides of Latin America 9: Measuring Erosion as a Component of Sustainability 10: Agronomic Consequences of Soil Erosion 11: Catchment Approach to Combating Soil Erosion in Asia - the Managing Soil Erosion Consortium 12: Latest Developments in the Design of Hydrological Studies of Watersheds 13: Off-site Impacts and Nutrient Dynamics in Catchment Research 14: On-site Nutrient Depletion: An Effect and a Cause of Soil Erosion 15: Erosion and Sedimentation as Multiscale, Fractal Processes: Implications for Models, Experiments and the Real World 16: Soil Erosion Research in Indonesia: Past Experience and Future Direction 17: Dynamic Process Modelling of Hydrology and Soil Erosion 18: The Measurement of Soil Erosion 19: The Use of GIS and Remote Sensing Techniques to Predict Erosion in the Nepal Middle Hills 20: Predicting Erosion and Sediment Yield at the Catchment Scale 21: Modelling Catchment Erosion, Sediment and Nutrient Transport in Large in Large Basins 22: Designing and Implementing Outcome-oriented Soil Conservation Research

Book SynopsisThis book describes how competition between plant species, and succession in plant ecosystems, operate in grasslands and grazed pastures, both natural and sown. It discusses how competition both affects botanical structure, productivity and persistence of pastures and is itself regulated by biological, environmental and management factors, such as grazing animals. The book also examines the ways in which competition and succession are analysed, evaluated and measured, and brings to the agricultural arena the considerable progress made in understanding the principles of competition from theoretical and experimental ecology.Table of Contents1: Competition and Succession in Pastures - Some Concepts and Questions, P Tow and A Lazenby 2: Measurement of Competition and Competition Effects in Pastures, N R Sackville Hamilton 3: Genotype and Environmental Adaptation as Regulators of Competitiveness, IG M O Nurjaya and P G Tow 4: Competition Between Grasses and Legumes in Established Pastures, A Davies 5: Plant Competition in Pastures - Implications for Management, D R Kemp and W McG King 6: Diversity and Stability in Humid Temperate Pastures, E A Clark 7: The Population Dynamics of Pastures, with Particular Reference to Southern Australia, E C Wolfe and B S Dear 8: Formulation of Pasture Seeds Mixtures with Reference to Competition and Succession in Pastures, W Harris 9: Effects of Large Herbivores on Competition and Succession in Natural Savanna Rangelands, C Skarpe 10: Competition and Environmental Stress in Temperate Grasslands, D A Peltzer and S D Wilson 11: Interaction of Competition and Management in Regulating Composition and Sustainability of Native Pasture, D L Garden and T P Bolger 12: Global Climate Change Effects on Competition and Succession in Pastures, B D Campbell and D Y Hunt 13: Competition and Succession in Re-created Botanically Diverse Grassland Communities, R Chapman 14: Implications of Competition Between Plant Species for the Sustainability and Profitability of a Virtual Farm Using a Pasture-Wheat Rotation, B R Trenbath 15: Some Concluding Comments, A Lazenby and P G Tow 16: Index
