This study of China blends historical documentation with contemporary assessment to determine the degree of human impact upon the country's vegetation, soils, water, air and wildlife. This introduces the development of environmental ideas as found in the ancient Chinese classics and traces the history of vegetation degradation. The pattern of land degradation is described with emphasis on soil erosion and desertification. Pollution, which increased dramatically throughout the 1980s, is analyzed employing national statistics and local examples; the various policies recently introduced for pollution control are assessed. Wildlife management is scrutinized largely through a discussion of the evolution of China's nature reserve network. Regional variation in degradation and protection is stressed throughout. Aiming to fill a gap in the literature on China's environment by providing a comprehensive assessment of China's environment as of the early 1990s, this book is designed as a reference, both for understanding the historical scope of environmental degradation and for assessing attempts to control environmental degradation since the 1980s.

Civilization's negative impact on the environment has vastly accelerated since the onset of the industrial revolution. Serious environmental contamination now threatens many ecosystems and perhaps ultimately the human race. While some of the most visible urban pollution may have abated, the larger problems of regional and global pollution, particularly by an ever-increasing number of trace contaminants, remain far from solved. While the link has been clearly established between long-range transport of gaseous pollutants and environmental issues such as acid rain, the greenhouse effect, and Arctic haze, the scientist's understanding of the fate of these pollutants in the atmosphere has been constrained by the lack of suitable analytical methods, the complexities of pollution sources, and the volume of potential contaminants involved. This volume offers some of the research tools needed to begin untangling these riddles: appropriate measurement technology, sophisticated analytical techniques, and a better understanding of physical and chemical processes in the atmosphere. Chapters by leading environmental scientists from the world over discuss: . Standard and new methods of sampling and analyzing gaseous contaminants in the atmosphere. The uses of these analytical methods in deciphering material fluxes. The sources, occurrences, and characterization of volatile organic compounds in both indoor and outdoor environments. Gaseous Pollutants will be of great interest to scientists and engineers interested in monitoring air quality; atmospheric chemists studying the behavior and fate of trace contaminants in the air; and anyone concerned with air pollution and pollution control strategies. Inaddition to presenting a valuable profile of current research results, this book outlines the challenges that lie ahead, pointing students and environmental professionals alike toward important research opportunities in this dynamic field.

Protecting environmental quality while pursuing economic development poses a particularly difficult challenge to the countries of Central and Eastern Europe, where political and economic systems are changing rapidly following decades of environmental neglect and economic mismanagement. Advanced industrial nations also face difficult decisions about priorities and procedures for providing financial assistance to the region. In order to identify workable solutions, Pollution Abatement Strategies in Central and Eastern Europe investigates some of the leading pollution problems that these countries now face and examines the link between economic restructuring and environmental improvement. Contributors to the volume assess the changes in the region's environmental conditions likely to result from economic restructuring and the benefits that might arise from improvements. They also consider the design of effective environmental policies for economies in transition, including the need to introduce or reform basic economic, legal, and regulatory constructs. Comparisons of incentive-based versus command-and-control environmental policies suggest that, despite the difficulties in implementing them, incentive-based policy options are worth pursuing in Central and Eastern Europe.

Why do some states enact stronger pollution control progammes than others? And, do stronger controls have identifiable impacts on environmental quality in these states? This work seeks to answer these question by means of combining data, methods and theory from the natural and social sciences.

Environmental pollution resulting from widespread pesticide application has become a serious worldwide problem. Plant Pathogenesis and Disease Control is an important new reference that addresses this problem by exploring the biochemical and molecular mechanisms of plant pathogenesis and emphasizing the use of "pest control agents" rather than "pesticides" for plant disease control. Topics examined include pathogenicity, the resistance of plants against pathogens, the offensive and defensive struggle between hosts and parasites, methods for using natural defense mechanisms to develop environmentally sound disease control agents, and the use of modern biotechnology for plant disease control. The book will be an essential reference for phytopathologists, plant biochemists, pesticide chemists, mycologists, plant cell technologists, and agricultural researchers.

Rice is the staple food for half of the world's population. Consumption of rice is the major exposure route globally to the class one, non-threshold carcinogen inorganic arsenic. This book explains the sources of arsenic to paddy soils and the biogeochemical processes and plant physiological attributes of paddy soil-rice ecosystems that lead to high concentrations of arsenic in rice grain. It presents the global pattern of arsenic concentration and speciation in rice, discusses human exposures to inorganic arsenic from rice and the resulting health risks. It also highlights particular populations that have the highest rice consumptions, which include Southern and South East Asians, weaning babies, gluten intolerance sufferers and those consuming rice milk. The book also presents the information of arsenic concentration and speciation in other major crops and outlines approaches for lowering arsenic in rice grain and in the human diet through agronomic management.

Assessing natural resource damages often requires the use of nonmarket valuation techniques that were developed for use in benefit-cost analyses. Natural resource damage assessment dramatically changes the context for applying them. Two aspects of this context are especially important. First, damages are to be measured by the monetary value of the losses people experience, including their use and nonuse values, because of injuries to natural resources---a process requiring careful delineation of how the injuries connect to the resource's services. Second, a single identified entry---not generalized, anonymous taxpayers---must pay damages based on what is measured, and evaluations of the measurement techniques take place not in agency meeting rooms but in courtrooms. Contributors to Valuing Natural Assets examine the ways in which requirements for damage assessment change how the measures are used, presented, received, and defended. Drawing upon their personal involvement with the process and the research issues it has raised---both in providing analysis for defendants or plaintiffs in damage assessment cases and in writing for academic journals---their chapters reflect individual research programs that temper the rigorous demands of scholarship with the equally demanding standards of litigation.
