Landslides in sensitive clays represent a major hazard in the northern countries of the world such as Canada, Finland, Norway, Russia, Sweden and in the US state of Alaska. Past and recent examples of catastrophic landslides at e.g. Saint-Jean-Vianney in 1971, Rissa in 1979, Finneidfjord in 1996 and Kattmarka in 2009 have illustrated the great mobility of the remolded sensitive clays and their hazardous retrogressive potential. These events call for a better understanding of landslide in sensitive clay terrain to assist authorities with state-of-the-art hazard assessment methods, risk management schemes, mitigation measures and planning. During the last decades the elevated awareness regarding slope movement in sensitive clays has led to major advances in mapping techniques and development of highly sophisticated geotechnical and geophysical investigation tools. Great advances in numerical techniques dealing with progressive failure and landslide kinematic have also lead to increase understanding and predictability of landslides in sensitive clays and their consequences. This volume consists of the latest scientific research by international experts dealing with geological, geotechnical and geophysical aspects of slope failure in sensitive clays and focuses on understanding the full spectrum of challenges presented by landslides in such brittle materials.

This volume illustrates the complex root system, including the various essential roles of roots as well as their interaction with diverse microorganisms localized in or near the root system.

Following initial chapters describing the anatomy and architecture as well as the growth and development of root systems, subsequent chapters focus on the various types of root symbiosis with bacteria and fungi in the rhizosphere. A third section covers the physiological strategies of roots, such as nitrate assimilation, aquaporins, the role of roots in plant defense responses and in response to droughts and salinity changes. The book s final chapters discuss the prospects of applied engineering of roots, i.e., inventing new root structures or functions through genetic modification, but also with conventional breeding and manipulation of root symbionts. The budding field of root engineering is expected to promote a second green revolution."

I write because I am concerned that I and my agricultural colleagues have avoided addressing the moral dimension of the environmental and social problems we have contributed to. I hope for an exchange of ideas about agriculture's moral dilemmas. I encourage my readers to engage in a collective conversation about the dilemmas and avoid remaining in what Merton calls "the collective arrogance and despair of his own herd." If those engaged in agriculture continue to ignore and fail to realize our common difficulties they will be addressed and resolved by societal pressure and political action, which may not yield the resolution we favor. The book's goal is not to resolve the moral dilemmas raised. It is to raise them and encourage thought and discussion. It will ask but not answer why nearly all involved in agriculture have not addressed the moral concerns voiced by the general public. The agricultural enterprise is committed to the benefits and future success of the present, very productive, chemical, capital, and energy intensive system, which is, in the minds of many, not sustainable. The internal justification invokes the moral claim that they feed the world's population. The question remains whether or not the prevailing moral justification of feeding the world is adequate given all the issues modern, developed country agriculture faces: pesticides in soil, water, and food, cruelty to animals, Biotech/GMO's, corporate agriculture, pollution by animal factory waste, exploitation of and cruelty to migrant labor.

This book represents a rather complicated history of encounters, changes in research interest and some very interesting results. Initially it is the very fruitful interaction of Ecology and Geology. The point of view of ecologists is extremely refreshing for hard science people. Interaction and inter-relationships are the focus of Ecology whereas the traditional sciences, such as Geology, have tried to isolate the natural phenomena so that thye could be studied in a more rigorous manner. The traditional sciences were of course natural science - based since the world to be observed was at the door step of everyone, mountains, weather patterns, plants and so forth. Chemistry and Physics were de ned after Mathematics in order to establish more precise and viable principles of the behavior of the materials that formed the world around mankind. It became quite clear that the observation of the natural world was too complicated to consider all of the possible variables which could affect an observed process or situation. The systems were simpli ed and taken into the laboratory in order to better master the phenomena observed. Physics c- cerned itself with non-reacting materials, subjected to essentially mechanical forces.

This thesis presents an impressive summary of the potential to use passive seismic methods to monitor the sequestration of anthropogenic CO2 in geologic reservoirs. It brings together innovative research in two distinct areas - seismology and geomechanics - and involves both data analysis and numerical modelling. The data come from the Weyburn-Midale project, which is currently the largest Carbon Capture and Storage (CCS) project in the world. James Verdon's results show how passive seismic monitoring can be used as an early warning system for fault reactivation and top seal failure, which may lead to the escape of CO2 at the surface.

Do we actually understand geologic processes? New technology brings new inf- mation and perceptions, which sometimes overturn imaginations based on simple observation and estimation, in conjunction with common sense inference. In 1902- 1904,PierreCurieandErnestRutherford?rstformulatedtheideaofusingradioactive transformation of nuclides as a geologic chronometer. After a century of working with such tools, geology has advanced from a descriptive science to an analytic s- encethatformulatesconclusionsbasedonexactvalues.Thetechnologyofradiogenic isotope geology has created a branch of science that considers the Earth as a planet generated within a Solar system and studies the subsequent evolution of geologic processes that has resulted in the present formation of our planet's continents and oceans. The physicist Vitaly Ginsburg, Nobel Prize laureate, wrote recently: "If Kepler had been given information on orbital parameters of planets with modern precision, he would not have been able to formulate his laws". Indeed, after development of laws of celestial mechanics, methods of measurements became so advanced and such numerous secondary distortion effects were found that to describe an orbit of a cosmic body by a curve of the second order would appear impossible. But it does not mean that Kepler's laws are "cancelled"; they still occupy an honorable place in courses on celestial mechanics. A reasonable division into basic and secondary phenomena is accepted and the latter are entered as variations in the basic equations.

This book combines soil science, earth science, and environmental geochemistry, providing comprehensive background information for specialists interested in chemical-induced changes in the soil-subsurface system. Readers are introduced to the chemistry of contaminants that often disturb the natural soil-subsurface equilibrium as a result of human activity. While the soil-subsurface system has in many cases been affected by human impact, the effects of chemical contaminants on the actual matrix and properties have been largely neglected. The major focus of the book is on changes to the soil-subsurface matrix and properties caused by chemical pollution. By integrating results available in the literature, we observe that chemical pollutants may lead to the irreversible formation of a new soil-subsurface regime characterized by a matrix and properties different than those of the natural regime. In contrast to the geological time scales dictating natural changes to the matrix and properties of the soil-subsurface system, the time scale associated with chemical pollutant-induced changes is far shorter and extends over a "human lifetime scale." The numerous examples presented in the book confirm that chemical contamination should be considered as an additional factor in the formation of a contemporary soil-subsurface regime that is different than that of the pristine system.

The Baltic Sea is an area extensively explored by the oceanographers. Hence it is one of the most often described marine areas in the scientific literature. However, there are still several fields which are poorly investigated and reported by scientists. One of them is the carbon cycle of the Baltic Sea. Although it is believed the shelf seas are responsible for about 20% of all marine carbon dioxide uptake, while they constitute only 7% of the whole sea surface, still a scientific debate exists on the role of the Baltic Sea in the global carbon cycle. "Carbon cycle of the Baltic Sea" is intended to be a comprehensive presentation and discussion of state of the art research by biogeochemists involved in the Baltic Sea carbon cycle research. This work presents both qualitative and quantitative descriptions of the main carbon flows in the Baltic Sea as well as their possible shifts induced by climatic and global change.

Human footprints provide some of the most emotive and tangible evidence of our ancestors. They provide evidence of stature, presence, behaviour and in the case of early hominin footprints, evidence with respect to the evolution of human gait and foot anatomy. While human footprint sites are rare in the geological record the number of sites around the World has increased in recent years, along with the analytical tools available for their study. The aim of this book is to provide a definitive review of these recent developments with specific reference to the increased availability of three-dimensional digital elevation models of human tracks at many key sites. The book is divided into eight chapters. Following an introduction the second chapter reviews modern field methods in human ichnology focusing on the development of new analytical tools. The third chapter then reviews the major footprint sites around the World including details on several unpublished examples. Chapters then follow on the role of geology in the formation and preservation of tracks, on the inferences that can be made from human tracks and the final chapter explores the application of this work to forensic science. Audience: This volume will be of interest to researchers and students across a wide range of disciplines - sedimentology, archaeology, forensics and palaeoanthropology.

This volume explores the various functions and potential applications of mycorrhizas, including topics such as the dynamics of root colonization, soil carbon sequestration and the function of mycorrhizas in extreme environments. Some contributions focus on the use of arbuscular mycorrhizal fungi in various crop production processes, including soil management practices, their use as biofertilizers and in relation to medicinal plants. Other chapters elucidate the role of arbuscular mycorrhizal fungi in the alleviation of plant water stress and of heavy metal toxicity, in the remediation of saline soils, in mining-site rehabilitation and in the reforestation of degraded tropical forests. In addition to their impact in ecosystems, the economic benefits of applying arbuscular mycorrhizal fungi are discussed. A final chapter describes recent advances in the cultivation of edible mycorrhizal mushrooms.

The Dead Sea transform is an active plate boundary connecting the Red Sea seafloor spreading system to the Arabian-Eurasian continental collision zone. Its geology and geophysics provide a natural laboratory for investigation of the surficial, crustal and mantle processes occurring along transtensional and transpressional transform fault domains on a lithospheric scale and related to continental breakup. There have been many detailed and disciplinary studies of the Dead Sea transform fault zone during the last20 years and this book brings them together.

This book is an updated comprehensive coverage of the knowledge, based on recent studies of the tectonics, structure, geophysics, volcanism, active tectonics, sedimentology and paleo and modern climate of the Dead Sea transform fault zone. It puts together all this new information and knowledge in a coherent fashion."

Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio-economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro-ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.

This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

This compilation of techniques, methodologies and scientific data arises from a four-year Italian research project, which took place at university research stations in Turin, Piacenza, Naples and Potenza. Soil Organic Matter (SOM) represents an active and essential pool of the total organic carbon on the planet. Consequently, even small changes in this SOM carbon pool may have a significant impact on the concentration of atmospheric CO2. Recent new understanding of the chemical nature of SOM indicates that innovative and sustainable technologies may be applied to sequester carbon in agricultural soils. Overall results of the project have been applied to develop an innovative model for the prediction and description, both quantitatively and qualitatively, of carbon sequestration in agricultural soils. This book provides experts in different areas of soil science with a complete picture of the effects of new soil management methods and their potentials for practical application in farm management.

The female authors highlighted in this monograph represent a special breed of science writer, women who not only synthesized the science of their day (often drawing upon their own direct experience in the laboratory, field, classroom, and/or public lecture hall), but used their works to simultaneously educate, entertain, and, in many cases, evangelize. Women played a central role in the popularization of science in the 19th century, as penning such works (written for an audience of other women and children) was considered proper "women's work." Many of these writers excelled in a particular literary technique known as the "familiar format," in which science is described in the form of a conversation between characters, especially women and children. However, the biological sciences were considered more "feminine" than the natural sciences (such as astronomy and physics), hence the number of geological "conversations" was limited. This, in turn, makes the few that were completed all the more crucial to analyze.

The current scenario of increasing sensitivity towards the sustainable agriculture has given a large space to extensively utilize natural resources that are environmental friendly and are a good replacement of chemicals in agriculture. Application of organic additives in the sustainable disease management can provide new insight in sustenance of plant productivity along with improved host stress tolerance. In the present book we have focussed upon a range of organic strategies to control plant pathogens of wide spectrum in addition to maintaining robust plant health. A detailed account on the application of organic additives has been discussed, irrespective of their origin and nature. In addition, the methods of utilising these organic supplements in the management of plant diseases and promotion of plant yield in more economic way have also been presented with reference to developing, underdeveloped and developed countries. The book has included the works of eminent scholars from across the world thus flashing light on the key literature related to application of organic matters including phytoextracts, chopped leaves, composted organic manures and liquid manures in eco-friendly agriculture. The mechanisms underlying the effectiveness of these organic amendments in promoting plant health has also been presented and discussed in understandable ways.

This book discusses how sediments compact with depth and applications of the compaction trends. Porosity reduction in sediment conveniently indicates the degree of sediments compacted after deposition. Published empirical curves- the compaction curves- are depth-wise porosity variation through which change in pore spaces from sediment surface to deeper depths e.g. up to 6 km can be delineated. Porosity is derived from well logs. Compaction curves, referred to as the Normal Porosity Profile of shales, sandstones and shale bearing sandstones of different models are reviewed along with the different mechanical and chemical compaction processes. These compaction models reveals how porosity reduces depth-wise and the probable reason for anomalous zones. Deviation from these normal compaction trends may indicate abnormal pressure scenarios: either over- or under pressure. We highlight global examples of abnormal pressure scenarios along with the different primary- and secondary mechanisms. Well logs and cores being the direct measurements of porosity, well log is the only cost-effective way to determine porosity of subsurface rocks. Certain well logs can detect overpressure and the preference of one log above the other helps reduce the uncertainty. Apart from delineation of under-compacted zones by comparing the modeled- with the actual compaction, porosity data can also estimate erosion.

The book provides a synthesis of the methods used in microfacies analysis, the potential of microfacies in evaluating depositional environments and diagenetic history, and the application of microfacies data in the study of carbonate hydrocarbon reservoirs and the provenance of archaeological materials. The first part of the book (Microfacies Analysis) deals with field and laboratory methods; the description and significance of microfacies data; quantitative microfacies analysis; diagenetic processes and diagenetic products; common textural limestone classifications and specific classifications for reef limestones, non-marine carbonates, recrystallized limestones and mixed carbonate-siliciclastic rocks; biological controls of carbonate sedimentation; and fossils in thin section. The second part (Microfacies Interpretation) is focused on the methods of making of microfacies types; diagonsotic criteria of palaeoenvironmental conditons and processes; the importance of integrated facies analysis including mineralogical and geochemical data; the definition of depositional facies models, facies zones and standard microfacies types, and the recognition of depositional constraints influencing cyclic carbonates, reef limestones, cold-water carbonates, vent and seep carbonates and mixed carbonate-siliciclastic rocks. The last chapter deals with secular variations of facies features. The third part of the book (Practical Use of Microfacies) underlines the facies controls of reservoir and host rocks, the importance of microfacies and diagenesis for understanding technological properties of carbonate rocks and the destruction and conservation of carbonate objects, and discusses the potential of microfacies for archaeometrical studies. Nearly 230 instructive plates (30 in color)showing thin-section photographs with detailed explanations form a central part of the content.
