Download or read book International Code of Conduct on Pesticide Management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Download or read book Ecology of Shallow Lakes written by Marten Scheffer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework. The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems. Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University. Reviews `Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant `bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, `how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.' Simon Harrison in Journal of Ecology, 86 `The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls `mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.' Wolf Mooij in Aquatic Ecology, 32

Available in PDF, EPUB and Kindle. Book excerpt: an up-to-date authoritative reference designed primarily for students of economics but invaluable also to students of business and other social sciences and ideal for anyone who wants a brief explanation of an economic concept or institution The MIT Dictionary of Modern Economics is an up-to-date, authoritative reference designed primarily for students of business and other social sciences and ideal for anyone who wants a brief explanation of an economic concept or institution. In this fourth edition one entry in ten has been revised and one entry in twenty is new. Whereas the third edition increased the coverage of American institutions, this edition breaks new ground by including entries considered important from an Eastern European perspective. It also supplies comparative statistics on major economic variables for selected countries, describes the origins of widely used acronyms, and includes bibliographic references at the end of featured entries. The dictionary answers in a clear and concise way the enduring questions, which economists have considered for two centuries or more, as well as the issues of the moment, such as economic change in Europe, the problems of pollution, or the prospects for greater freedom of trade. With close to 2,800 entries it is comprehensive in its coverage of theory, national and international institutions, schools of thought, and important economists, including recent Nobel Prize winners. The dictionary was compiled initially by an experienced team of economists at Aberdeen University in the United Kingdom, and new authors have been recruited to provide international expertise, reflecting changes in the structure of the international economy. This fourth edition was prepared by John Cairns, Robert Elliott, Ian McAvinchey, and Robert Shaw, all of the Economics Department, University of Aberdeen.

Book excerpt: The motion of water on a uniformly sloping beach, just after a bore reaches the shore, is studied. The shllow-water equations are used to fomulate a singular hyperbolic problem, which is solved by the help of RIEMANN'S Method and of the trutural theory of quasilinear hyperbolic equations developed in gas dynmics. The shore line is found to advance suddenly with non-zero velocity and then to move up and down the beach with constant, negative acceleration. The solution s shown to contain limit lines indiating a rather unexpeted, secondary bore in the back-wsh. (Author).

Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Shows 55 color plates, documenting wetland indicators throughout the nation - with more than 34 soil plates and aerial photos Illustrates other wetland properties with more than 50 figures Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation Contents Wetland Definitions Wetland Concepts for Identification and Delineation Plant Indicators of Wetlands and Their Characteristics Vegetation Sampling and Analysis for Wetlands Soil Indicators of Wetlands Wetland Identification and Boundary Delineation Methods Problem Wetlands and Field Situations for Delineation Wetland Classification Wetlands of the United States: An Introduction, With Emphasis on Their Plant Communities Wetland Mapping and Photointerpretation

Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume handbook is a comprehensive account of the rapidly emerging and vibrant science of the ecological restoration of habitats and species. Ecological restoration aims to achieve complete structural, functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social, and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction, or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology in relation to manipulations and management of the biological, geophysical, and chemical framework.

Download or read book Rise Trading State written by Richard Rosecrance and published by Basic Books. This book was released on 1987-05-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: What will power look like in the century to come? Imperial Great Britain may have been the model for the nineteenth century, Richard Rosecrance writes, but Hong Kong will be the model for the twenty-first. We are entering the Age of the Virtual State -- when land and its products are no longer the primary source of power, when managing flows is more important than maintaining stockpiles, when service industries are the greatest source of wealth and expertise and creativity are the greatest natural resources.Rosecrance's brilliant new book combines international relations theory with economics and the business model of the virtual corporation to describe how virtual states arise and operate, and how traditional powers will relate to them. In specific detail, he shows why Japan's kereitsu system, which brought it industrial dominance, is doomed; why Hong Kong and Taiwan will influence China more than vice-versa; and why the European Union will command the most international prestige even though the U.S. may produce more wealth.
