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 Hydrosocial Territories and Water Equity written by Rutgerd Boelens and published by Routledge. This book was released on 2017-06-01 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bringing together a multidisciplinary set of scholars and diverse case studies from across the globe, this book explores the management, governance, and understandings around water, a key element in the assemblage of hydrosocial territories. Hydrosocial territories are spatial configurations of people, institutions, water flows, hydraulic technology and the biophysical environment that revolve around the control of water. Territorial politics finds expression in encounters of diverse actors with divergent spatial and political–geographical interests; as a result, water (in)justice and (in)equity are embedded in these socio-ecological contexts. The territory-building projections and strategies compete, superimpose and align to strengthen specific water-control claims of various interests. As a result, actors continuously recompose the territory’s hydraulic grid, cultural reference frames, and political–economic relationships. Using a political ecology focus, the different contributions to this book explore territorial struggles, demonstrating that these contestations are not merely skirmishes over natural resources, but battles over meaning, norms, knowledge, identity, authority and discourses. The articles in this book were originally published in the journal Water International.

Download or read book Globalized Water written by Graciela Schneier-Madanes and published by Springer Science & Business. This book was released on 2014-05-01 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globalized Water presents a compilation of voices that forms a unique scientific exploration of contemporary water management models and governance issues. The book describes the water paradox—how a local resource has become a global product—and the implications of this in how we identify challenges and make policy in the water sector. Over the last 20 years, the foundations of local and national water systems have been rocked by a wave of changes. The authors in this book, experts in a wide range of disciplines, address the resulting debates and issues: water as a commodity and patrimony, technological rent, liberalization and privatization, the continuing evolution of water management and policy at the European level, decision making and stakeholder participation, conflict and consensus, and the inevitable growth of counterpowers at the local and international levels, promoted by the advocates of sustainable development. The selected case studies are from Europe (primarily France but also Spain, Germany, the United Kingdom, and Portugal), Latin America (Argentina, Bolivia), the United States, Lebanon, and India. From this diverse collection of comparative perspectives and research methods, Globalized Water seeks to advance interdisciplinary research, contributing to a new and dynamic role for social sciences and governance on water.

Available in PDF, EPUB and Kindle. Book excerpt: The concept of integrated water resources management has rapidly gained widespread currency. As attempts to formulate a global vision for water are on the increase, it is important to clarify this concept so that it does not degenerate into an empty slogan. This important volume of 17 original essays, establishes the crucial relationship between the multiple uses of water resources on the one hand and food security and rural development on the other, and suggests innovative approaches and methodologies that can help resolve the deadlock in water resources development and management.

Download or read book Econom a y pol tica de gesti n del agua en la agricultura written by JOSE MARIA SUMPSI and published by . This book was released on 1998 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: En España se da la paradoja que existiendo una larga tradición de política hidráulica, de instituciones para la gestión del agua y de tecnología de regulación, transporte, distribución y aplicación del agua en sus distintos usos, apenas se han desarrollado estudios sobre la economía del agua. Esta circunstancia responde a que en nuestro país la aproximación a la política hidráulica y a la planificación hidrológica se ha producido históricamente desde una perspectiva exclusivamente técnica y no económica. El presente libro desarrolla, a lo largo de los primeros capítulos, los principios básicos de la economía y política de gestión del agua y resume las experiencias internacionales más relevantes sobre políticas de oferta y demanda. La segunda parte, y núcleo central del libro, presenta los resultados de una exhaustiva investigación llevada a cabo en quince zonas regables pertenecientes a las cuencas hidrográficas del Duero, Guadiana, Guadalquivir, Júcar y Segura que ha permitido estimar las curvas de demanda de agua de dichas zonas regables y evaluar diversas políticas de gestión del agua en la agricultura española, propuesta desde distintos ámbitos. La investigación se ha llevado a cabo mediante un convenio entre la UPM y el MAPA bajo la dirección de José Ma Sumpsi Viñas, catedrático de dicha universidad. El carácter híbrido del libro, conceptual y teórico por un lado pero empírico y aplicado por otro, hace que su lectura sea interesante tanto para alumnos y estudiosos del tema como para profesionales vinculados a la agricultura del regadío, así como para responsables de la gestión del agua en el sector agrario, sector que en España, al igual que en la mayoría de los países mediterráneos, utiliza la mayor parte de los recursos hídricos disponibles.

Download or read book Los instrumentos econ micos en la gesti n del agua en la agricultura written by JOSE ALBIAC MURILLO and published by Mundi-Prensa Libros. This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: La escasez y la sobreutilización del agua dulce plantean una creciente y seria amenaza al desarrollo sostenible y a la protección del medio ambiente. La deficiente gestión de los recursos hídricos y del uso de la tierra pone en peligro la salud y el bienestar humano, la seguridad alimentaria, el desarrollo industrial y los ecosistemas ligados a los recursos hídricos. Esta deficiencia en la gestión ha sido reconocida por los gobiernos y organizaciones internacionales, y las propuestas de la Unión Europea y Naciones Unidas se basan en la utilización de los instrumentos económicos para conseguir el uso sostenible de los recursos hídricos. Este libro es el resultado del Seminario Internacional de Gestión de Demanda de Agua, que se celebró en 2002 en Zaragoza, y en el que participaron varios expertos que trabajan en el campo de la economía y la política del agua. El libro presenta la contribución de estos expertos que analizan los instrumentos económicos en la gestión de los recursos hídricos, y que examinan desde enfoques teóricos, empíricos, e institucionales la utilización de estos instrumentos para conseguir un uso sostenible del agua en la agricultura. El libro está dirigido a los estudiosos y profesionales vinculados a la gestión de los recursos hídricos, en sus facetas económica, ecológica e hidrológica, y a los asesores y responsables de la toma de decisiones en la administración pública, la empresa privada, las organizaciones sociales y los grupos de presión.
