Myron Weiner's study of the relationship between internal migration and ethnic conflict in India is exceptional for two reasons: it focuses on intercultural and interstate migration throughout the nation, rather than on merely local or provincial phenomena, and it examines both the social and the political consequences of India's interethnic migrations. Professor Weiner examines selected regions of India in which migrants dominate the modern sector of the economy. He describes the forces that lead individual Indian citizens to move from one linguistic-cultural region to another in search of better opportunities, and he attempts to explain their emergence at the top of the occupational hierarchy. In addition, the author provides an account of the ways in which the indigenous ethnic groups ("sons of the soil") attempt to use political power to overcome their fears of economic defeat and cultural subordination by the more enterprising, more highly skilled, better educated migrants. In addressing the fundamental clash between the migrants' claims to equal access to their country and the claims of the local groups to equal treatment and protection by the state, Professor Weiner considers some of the ways in which government policy makers might achieve greater equality among ethnic groups without simultaneously restricting the spatial and social mobility of some of its own people.

Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

Landscapes viewed from afar have a timeless quality that is soothing to the human spirit. Yet a tranquil wilderness scene is but a snapshot in the steady stream of surficial change. Wind, water and human activities reshape the landscape by means of gradual to catastrophic and usually irreversible events. Much of this change destroys past landscapes, but at some times and places, landscapes are buried in the rock record. This work is dedicated to the discovery of past landscapes and their life through the fossil record of soils. A long history of surficial changes extending back almost to the origin of our planet can be deciphered from the study of these buried soils, or paleosols. Some rudiments of this history, and our place in it, are outlined in a final section of this book. But first it is necessary to learn something of the language of soils, of what happens to them when buried in the rock record and which of the forces of nature can be confidently reconstructed from their remains. Much of this preliminary material is borrowed from soil science, but throughout emphasis is laid on features that provide most reliable evidence of landscapes during the distant geological past. This book has evolved primarily as a text for senior level university courses in paleopedology: the study of fossil soils.

This book makes a rare and original contribution on the history of little documented internal land conflicts and boundary misunderstandings in Cameroon, where attention has tended to focus too narrowly on international boundary conflicts such as that between Cameroon and Nigeria. The study is of the Bamenda Grassfields, the region most plagued by land and boundary conflicts in the country. Despite claims of common descent and cultural similarities by most communities in the region, relations have been tested and dominated by recurrent land and boundary conflicts since the middle of the 20th Century. Nkwi takes us through these contradictions, as he draws empirically and in general on his rich historical and ethnographic knowledge of the tensions and conflicts over land and boundaries in the region to situate and understand the conflicts between Bambili and Babanki-Tungoh - the epicenter of land and boundary - from c.1950s - 2009. Little if any scholarly attention has focused on this all important issue, its pernicious effects on the region notwithstanding. This book takes a bold step in the direction of the social history of land and boundary conflicts in Cameroon, and demonstrates that there is much of scholarly interest in understanding the centrality of land and boundaries in the configuration and contestation of human relations. In his innovative and stimulating blend of history and ethnography, Nkwi points to exciting new directions of paying closer attention to relationships informed by consciousness on and around land and boundaries.

A guide to soil analysis for chemists and environmental scientists Soil-so essential to life on earth-is one of the most complicated of materials. A complex mixture of inorganic and organic solids, liquids, and gases, soil presents a challenging material for analysis, especially for researchers who are not specialists in soil chemistry. This clear, broadly applicable reference provides chemists and environmental scientists with the background they need to analyze soil, interpret their findings, and develop new analytical methods for soil. Introduction to Soil Chemistry will also be valuable to the soil scientist confronting soil analyses that appear to be incorrect or do not work. Introduction to Soil Chemistry: Analysis and Instrumentation investigates the most important soil characteristics that impact analysis and the procedures, chemicals, and equipment used to determine the composition and quantity of soil constituents. It also discusses factors that interfere with accurate soil analysis. Chapters examine such topics as: * Large features-horizons, peds, soil color, and soil naming * Microscopic to atomic orbital description of soil chemical characteristics * Soil components in combination * The biological and organic components in soil * The soil solution and soil air * Electrical measurements, titration, and extraction * Spectroscopy and chromatography * Speciation This book is enhanced by numerous examples within the text, which provide the reader with a practical understanding of various analytical procedures, along with the pitfalls and interferences that may be encountered. Bibliographies and additional resources appear at the end of each chapter.
