A decade ago no one except geologists had heard of tantalum or 'coltan' – an obscure mineral that is an essential ingredient in mobile phones and laptops. Then, in 2000, reports began to leak out of Congo: of mines deep in the jungle where coltan was extracted in brutal conditions watched over by warlords. The United Nations sent a team to investigate, and its exposé of the relationship between violence and the exploitation of coltan and other natural resources contributed to a re-examination of scholarship on the motivations and strategies of armed groups. The politics of coltan encompass rebel militias, transnational corporations, determined activists, Hollywood celebrities, the rise of China, and the latest iGadget. Drawing on Congolese and activist voices, Nest analyses the two issues that define coltan politics: the relationship between coltan and violence in the Congo, and contestation between activists and corporations to reshape the global tantalum supply chain. The way production and trade of coltan is organised creates opportunities for armed groups, but the Congo wars are not solely, or even primarily, about coltan or minerals generally. Nest argues the political significance of coltan lies not in its causal link to violence, but in activists' skillful use of mobile phones as a symbol of how ordinary people and transnational corporations far from Africa are implicated in Congo's coltan industry and therefore its conflict. Nest examines the challenges coltan initiatives face in an activist 'marketplace' crowded with competing justice issues, and identifies lessons from coltan initiatives for the geopolitics of global resources more generally.

The control of diseases in crops is still largely dominated by the use of fungicides, but with the increasing incidence of fungicide resistance, plus mounting concern for the environment resulting from excessive agrochemical use, the search for alternative, reliable methods of disease control is gaining momentum. The purpose of this important book is to examine the development and exploitation (or potential for exploitation) of a range of non-chemical approaches to disease control, with a focus on the need for a greater understanding of crop ecology as the basis for effective disease control in the field. Chapters in the book, written by international experts in the subject area, include coverage of: biological control methods host-plant resistance the exploitation of tolerance and the use of bacteriophages Carefully edited by Professor Dale Walters, widely respected for his work in the area of crop protection, Disease Control in Crops is an essential reference book for plant pathologists, microbiologists, plant and agricultural scientists and crop protection specialists, including those working within, and providing consultancy to, the agrochemical industries. Libraries in all universities and research establishments where biological sciences and agriculture are studied and taught should have copies of this timely publication on their shelves.

The movement of sediment and associated pollutants over the landscape and into water bodies is of increasing concern with respect to pollution control, prevention of muddy floods and environmental protection. In addition, the loss of soil on site has implications for declining agricultural productivity, loss of biodiversity and decreased amenity and landscape value. The fate of sediment and the conservation of soil are important issues for land managers and decision-makers. In developing appropriate policies and solutions, managers and researchers are making greater use of erosion models to characterise the processes of erosion and their interaction with the landscape. A study of erosion requires one to think in terms of microseconds to understand the mechanics of impact of a single raindrop on a soil surface, while landscapes form over periods of thousands of years. These processes operate on scales of millimetres for single raindrops to mega-metres for continents. Erosion modelling thus covers quite a lot of ground. This book introduces the conceptual and mathematical frameworks used to formulate models of soil erosion and uses case studies to show how models are applied to a variety of purposes at a range of spatial and temporal scales. The aim is to provide land managers and others with the tools required to select a model appropriate to the type and scale of erosion problem, to show what users can expect in terms of accuracy of model predictions and to provide an appreciation of both the advantages and limitations of models. Problems covered include those arising from agriculture, the construction industry, pollution and climatic change and range in scale from farms to small and large catchments. The book will also be useful to students and research scientists as an up-to-date review of the state-of-art of erosion modelling and, through a knowledge of how models are used in practice, in highlighting the gaps in knowledge that need to be filled in order to develop even better models.

A functional discussion of the crop selection process for biomass energy The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing provides a detailed examination and analysis for a number of energy crops and their use as a source for generating electricity and for the production of bio-fuels. Renowned renewable energy expert and consultant Dr. Najib Altawell begins with the fundamentals of bio-fuels and co-firing and moves on to the main feature, which is the methodology that assists energy scientists and engineers to arrive at the most suitable biomass materials tailored to each company’s business and economic environments and objectives. This methodology provides a framework whereby power-generating companies can insert their own values for each factor, whether business factor (BF) or scientific & technical factors (S&T) or both simultaneously. The methodology provides a list of factors related to the biomass energy business. The average values have been obtained from the survey method and laboratory tests. These values are the standard values power companies can use if they need or wish to use them. The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing has been designed and compiled for the widest possible range of readers, researchers, businesspeople, and economists who are connected to the renewable energy field in general, and biomass energy in particular. Because of its focus on practical data and applications, the book is also accessible for general readers who may or may not have a technical or scientific background.

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.
Historically, the conservation of forests and wildlife has focused on the creation of national parks and reserves. However, only 9% of protected areas are larger than 14,000 hectares, likely making them too small to conserve ecosystem services and prevent loss of wide-ranging keystone species such as elephant and leopard. New approaches are needed that extend conservation beyond protected area boundaries into areas where economic considerations prevail. The book describes one such emerging model of conservation: the integration of the private sector into partnerships to protect biodiversity and improve forest management. While such partnerships are being created in nearly every sector of resource extraction, detailed analyses of how such partnerships work and whether they benefit biodiversity conservation are rare. Using a case study from the Congo Basin, the book examines principles of conservation and partnership, and provides technical and methodological details to replicate an innovative conservation model. It presents concrete solutions for expanding conservation across multi-use landscapes, a necessary action as industry expands to all the corners of the globe.
The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions. This is followed by a new chapter on the unique tropical rain forests of oceanic islands. The final chapter, which has been completely rewritten, deals with the impacts of people on tropical rain forests and discusses possible conservation strategies that take into account the differences highlighted in the previous chapters. This exciting and very readable book, illustrated throughout with color photographs, will be invaluable reading for undergraduate students in a wide range of courses as well as an authoritative reference for graduate and professional ecologists, conservationists, and interested amateurs.
