Natural Disasters and Extreme Events in Agriculture : Impacts and Mitigation

Agricultural production is highly dependent on weather, climate and water availability and is adversely affected by the weather and climate-related disasters. Droughts and natural disasters such as floods can result in crop failures, food insecurity, famine, loss of property and life, mass migration and negative national economic growth. It may not be possible to prevent the occurrence of these natural disasters, but the resultant disastrous effects can be reduced considerably through proper planning and effective preparation. Vulnerability associated with the hazards of natural disasters can be controlled to some extent by accurate and timely prediction and by taking counter-measures to reduce their impacts on agriculture. This book based on an expert meeting held in Beijing, China should be of interest to all organizations involved in disasters reduction and mitigation of extreme events.

Microbiology of Extreme Soils

This volume provides an excellent introduction to the study of extreme soil micro-biology, and a variety of the challenging and fascinating environments that Earth-bound microbes face. Some are natural, and some are the result of human activity, and all of them have lessons to teach us about life’s adaptations within the “extreme” hori-zons of terrestrial soils. What’s more, each of these chapters (including the chapter on the soils of Mars by Ronald L. Crawford and David A. Newcombe) can give us insights into strategies that may make life possible beyond the safe confines of our present-day biosphere, to other worlds in this solar system and beyond

International conference on terrain and geohazard challenges facing onshore oil and gas pipelines : Evaluation, routing, resign, construction, operation ; Proceedings of a three day international conference on terrain and geohazard challenges facing onshore oil and gas pipelines, organised by the Institution of Civil Engineers in association with BP Exploration and held at the Institution of Civil Engineers, London, UK, on 2 – 4 June 2004

To access global oil and gas deposits, major pipelines must traverse remote regions with extreme terrains. There are a significant number of pipeline projects, active or planned, in tropical jungles, mountains and deserts, in permafrost and in areas of wetland. Each of these natural environments is associated with a range of geohazards, which may include landslides, soil erosion, karst, river migration, and seismic or volcanic activity. At the same time, society demands increasing availability and reliability of supply, together with improved environmental standards, all making for substantial challenges.

Global Change and Mountain Regions : An Overview of Current Knowledge

Mountain regions occupy about a quarter of the global terrestrial land surface and provide goods and services to more than half the humanity. Global environmental change threatens the integrity of these systems and their ability to provide the goods and services upon which humanity has come to depend. This book gives an overview of the state of research in fields pertaining to the detection, understanding and prediction of global change impacts in mountain regions. More than 60 contributions from paleoclimatology, cryospheric research, hydrology, ecology, and development studies are compiled in this volume, each with an outlook on future research directions.

Geology and Ecosystems

This book includes an analysis of the relationship between the different geological, hydrochemical, hydrogeological and engineering-geological processes and the processes within surface ecosystems. The analysis of specific interactions between the lithosphere and biosphere provides an integrated concept of the role of the geological environment in the evolution of the biosphere. The practical significance of the book is reflected by the analysis of modern engineering activity associated with the mining of minerals, excessive groundwater withdrawal, disposal of industrial and domestic wastes (including radioactive wastes) and their impacts on all components of the environment. Geology and Ecosystems includes a scientific approach to the complex monitoring of the environment under different natural and anthropogenic conditions, including the monitoring of permafrost regions. An important part of the book is the analysis of the "water factor" impact on ecosystems and sustainable development. Influences of intensive groundwater extraction on river flow, vegetation and land subsidence are also considered.

Economic Geology of Natural Gas Hydrate

This is the first book that attempts to broadly integrate the most recent knowledge in the fields of hydrate nucleation and growth in permafrost regions and marine sediments. Gas hydrate reactant supply, growth models, and implications for pore fill by natural gas hydrate are discussed for both seawater precursors in marine sediments and for permafrost hydrate. These models for forming hydrate concentrations that will constitute targets for exploration are discussed, along with exploration methods. Thermodynamic models for the controlled conversion of hydrate to natural gas, which can be recovered using conventional industry practices, suggest that a number of different types of hydrate occurrence are likely to be practical sources of hydrate natural gas. Current progress in the various aspects of commercial development of hydrate gas deposits are discussed, along with the principal extractive issues that have yet to be resolved.

Cold Region Atmospheric and Hydrologic Studies. The Mackenzie GEWEX Experience: Vol.2: Hydrologic Processes

This book presents decade-long advances in atmospheric research in the Mackenzie River Basin in northern Canada, which encompasses environments representative of most cold areas on Earth. Collaborative efforts by a team of about 100 scientists and engineers have yielded knowledge entirely transferable to other high latitude regions in America, Europe and Asia. Emphases are placed on the investigation of processes (including storm genesis, precipitation, moisture and energy fluxes and frost), and the improvement and application of a suite of models and remote sensing to enhance the assessment of climate variability and water resources.

Advances in the Geological Storage of Carbon Dioxide : International Approaches to Reduce Anthropogenic Greenhouse Gas Emissions

As is now generally accepted mankind’s burning of fossil fuels has resulted in the mass transfer of greenhouse gases to the atmosphere, a modification of the delicately-balanced global carbon cycle, and a measurable change in world-wide temperatures and climate. Although not the most powerful greenhouse gas, carbon dioxide (CO) drives climate 2 change due to the enormous volumes of this gas pumped into the atmosphere every day. Produced in almost equal parts by the transportation, industrial and energy-generating sectors, atmospheric CO concentrations have 2 increased by about 50% over the last 300 years, and according to some sources are predicted to increase by up to 200% over pre-industrial levels during the next 100 years. If we are to reverse this trend, in order to prevent significant environmental change in the future, action must be taken immediately.

A History of Limb Amputation

This book traces humanity’s long experience of natural amputations due to congenital absence, disease, frostbite, toxins, domestic and wild animal trauma, and for non-medical reasons related to punitive, ritual, and legal actions, ultimately leading to the development of elective surgical amputation. While the evolution of surgical techniques forms a major chapter in the book, many ancillary problems are addressed including the control of hemorrhage and infection, the approach to pain relief, the development of suitable instruments and equipment, and the invention of prostheses, all suitably illuminated with case histories and relevant illustrations. In addition, alternative procedures designed to avoid amputation, increasingly important in the last two centuries, are debated, and factors associated with self-amputation in extremis, not rare according to press reports, are also examined. A separate chapter considers the philosophy and interpretations of society, patients, and surgeons faced with amputation, particularly before anesthesia.
