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

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.

This book was released on 1998 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: To preserve the environment with the lowest possible cost to the social sector means that private costs should be aligned with social costs. Many governments in the Latin American and Caribbean Region are doing this now using market-based instruments (MBIs). This publication investigates the use of MBIs in the Latin America and the Caribbean (LAC) context. The investigation covers a sample of eleven countries in the region and a cross-section of environmental issues in an urban setting.

Available in PDF, EPUB and Kindle. Book excerpt: A study on urban risk and resettlement programs in the Global South in the era of climate change. Environmental changes impact everyone, but the burden is especially heavy upon the lives and livelihoods of the urban poor and those living in informal settlements. In an effort to reduce urban residents' exposure to climate change and natural disasters, resettlement programs are becoming widespread across the Global South. Yet, while resettlement may reduce a region's future climate-related disaster risk, it can also often increase poverty and vulnerability. This volume collates the findings from a research project that examined urban areas across the globe, including case studies from India, Uganda, Peru, Colombia, Mexico, Cambodia, and the Philippines. The book offers a unique approach to resettlement, providing an opportunity for urban planners to re-think how disaster risk management can better address the accumulation of urban risks in the era of climate change.

Download or read book The Global Restructuring of Agro Food Systems written by Philip D. McMichael and published by Cornell University Press. This book was released on 2019-05-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the world, food systems and agricultural systems are changing at a phenomenal rate. Widespread restructuring has not been confined to the production and distribution of food, though; many regions and even nations are undergoing social, political, and economic transformation as well. Bringing together twelve essays by scholars from a number of disciplines, I this timely book documents the interdependence of food systems, nation states, and the world economy. Stressing the political foundations of global agro-food systems, it sheds light on such complex questions as whether today's changes in food and agrarian systems anticipate a new world order, or are merely efforts to preserve an old order in crisis.

Download or read book Mixed Race Studies written by Jayne O. Ifekwunigwe and published by Routledge. This book was released on 2015-03-24 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed race studies is one of the fastest growing, as well as one of the most important and controversial areas in the field of race and ethnic relations. Bringing together pioneering and controversial scholarship from both the social and the biological sciences, as well as the humanities, this reader charts the evolution of debates on 'race' and 'mixed race' from the nineteenth to the twenty-first century. The book is divided into three main sections: tracing the origins: miscegenation, moral degeneracy and genetics mapping contemporary and foundational discourses: 'mixed race', identities politics, and celebration debating definitions: multiraciality, census categories and critiques. This collection adds a new dimension to the growing body of literature on the topic and provides a comprehensive history of the origins and directions of 'mixed race' research as an intellectual movement. For students of anthropology, race and ethnicity, it is an invaluable resource for examining the complexities and paradoxes of 'racial' thinking across space, time and disciplines.

Download or read book Regions at Risk written by Jeanne X. Kasperson and published by UN. This book was released on 1995 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced environmental change is to be found throughout the world, but there are areas that scientists consider to be "critical regions" - regions that are particularly vulnerable to or suffering from environmental degradation. In this volume nine such "critical environmental regions" (Amazonia, the Aral Sea basin, the middle mountains of Nepal, Kenya's Ukambani region, the US Southern High Plains, the Mexico Basin, the North Sea, the Ordos Plateau of China, and the eastern Sundaland region of South-East Asia) are examined as case-studies. In chapter one the authors provide a detailed look into the concepts of environmental criticality and endangerment and propose formal definitions. The nine regional studies that follow in the subsequent chapters serve to translate the conceptual framework into the physical and social realities of each area. The case-studies make available an up-to-date synthesis of vast amounts of inaccessible data, and as such will be valuable to scholars and policy makers interested in specific areas of the world and others interested in regional comparisons. Anyone concerned with global environmental change, criticality, human-environment interactions, and how societies in different regions have responded to environmental degradation will find much that is new and important in this pioneering, innovative study.
