A lo largo de la historia, el ser humano ha encontrado en los humedales una fuente feraz para proveerse de alimentos. Sin embargo, los humedales también albergaban impor-tantes peligros: no solo animales depredadores, sino tambien enfermedades como el paludismo, la fiebre amarilla y el dengue. Enfermedades que desde los años cincuenta y sesenta del pasado siglo se controlaron en buena medida, lo que contribuyo a que nos despojaramos de nuestros antiguos miedos y apreciaramos en ellos las riquezas y servicios que brindan.

ISBN: 9781780406350 Género: PDG:TQSW:TQSR Sinópsis: Water Management and Water Loss contains a selection of papers and articles written by various internationally recognised specialists in the field of water loss reduction. The articles have been drawn together from IWA conferences during the past 5 years and provide details of how water losses from Municipal distribution systems can be reduced. The book provides useful background information and reference materials to help explain the different approaches and interventions that are used to reduce water losses. Numerous real case studies are provided that highlight the processes and methodologies employed around the world to reduce water losses. Water Management and Water Loss covers many aspects of water loss control including, pressure management, leak detection and repair, Internal plumbing losses and retrofitting, community involvement and education/awareness, schools education and leak repair projects.

California presenta respecto a España notables paralelismos y similitudes, tanto en parámetros geoclimáticos como incluso en muchos aspectos de su historia hidráulica o en lo referente a niveles de regulacion y disponibilidad de caudales. Sin embargo, el profundo giro operado desde finales de los setenta en la politica hidraulica norteamericana ha generado un nuevo modelo de planificacion y gestion del agua que contrasta fuertemente con las concepciones e inercias desgraciadamente vigentes todavia en nuestro pais. En California prevalece el valor ambiental y ecologico del agua. De una estrategia de grandes obras para sustanciar una politica de oferta, se ha pasado a una estrategia de conservacion del recurso y de gestion de la demanda. En nuestro pais la necesidad de un giro historico similar que permita superar el obsoleto estructuralismo hidraulico, vigente hasta hoy, es ya inaplazable. En este sentido, la experiencia californiana puede ser de gran utilidad. En el presente libro, Pedro Arrojo, profesor titular del Departamento de Analisis Economico de la Universidad de Zaragoza, aprovechando los conocimientos adquiridos fundamentalmente durante su estancia en la Universidad de California-Davis como profesor invitado (curso 1994-1995), analiza la experiencia californiana en contraste con la realidad y las concepciones vigentes en España. Por otro lado, Jose Manuel Naredo, director del programa "Economia y Naturaleza" de la Fundacion Argentaria, y quizas el investigador español mas prestigioso en el area de la economia ecologica, valora las perspectivas de este necesario giro en la gestion y planificacion hidrologica desde su innovador y sugestivo enfoque economico-ecologico. Pedro Arrojo Agudo es doctor en Ciencias Fisicas por la Universidad de Zaragoza. Actualmente es profesor titular del Departamento de Analisis Economico de la Facultad de Economicas de Zaragoza. Centrada su actividad de estudio y de investigacio

An idiosyncratic richly illustrated guide to Britain s rivers seas and shores

An absolute treasure trove of sound advice and historical detail Katherine May A delightful and a profound meditation on the variety of human experience Ian Mortimer Lara Maiklem is a phenomenon She elevates trudging around in the mud to an epic gallivant through our past Dan SnowFor over two decades Lara Maiklem has been scouring the banks of the tidal Thames looking for objects lost or discarded that tell forgotten stories In this charming sequel to the bestselling Mudlarking Lara widens her search beyond the river and reflects on life lived post pandemic reminding us that it s possible to draw meaning in the most unlikely of places As she searches the foreshore through the changing seasons she is at times aided by the gentle illumination of the falling winter sun or hindered by bright summer skies and lashing rain Yet by working in harmony with the unpredictable terrain she finds solace in aligning with the elements and uncovering the treasures that are bestowed by the tide From medieval pilgrim badges and Tudor love tokens to Georgian wig curlers and Victorian pottery each passing day unearths ordinary and extraordinary objects that tell the rich story of London s past and its inhabitants A Mudlarking Year is a gentle ode to nature history and

Se analizan las causas de la salinización del acuífero, su evolución en el espacio-tiempo y su estado actual; además se modeliza el fenómeno y se exponen los riesgos que comporta y sus soluciones. La obra es de especial interes para investigadores y organismos encargados del estudio del agua.

Oil and natural gas represent more than 50 percent of the worldwide energy supply with high energy demand driven by population growth and improving standards of living Despite significant progress in reducing the amount of oil in the sea from consumption exploration transportation and production risks remain This report the fourth in a series documents the current state of knowledge on inputs fates and effects of oil in the sea reflecting almost 20 additional years of research including long term effects from spills such as the Exxon Valdez and a decade long boom in oil spill science research following the Deepwater Horizon oil spill The report finds that land based sources of oil are the biggest input of oil to the sea far outweighing other sources and it also notes that the effects of chronic inputs on the marine environment such as land based runoff are very different than that from an acute input such as a spill Steps to prevent chronic land based oil inputs include reducing gasoline vehicle usage improving fuel efficiency increasing usage of electric vehicles replacing older vehicles The report identifies research gaps and provides specific recommendations aimed at preventing future accidental spills and ensuring oil spill responders are equ

This textbook provides a complete introduction to Hydrogeology It is a comprehensive reference for earth science professionals involved in groundwater exploitation as well as for geotechnical engineers This English translation of the German textbook Hydrogeologie by Holting & Coldewey which has been published in its 8th edition provides insights into the sources and reservoirs of groundwater the dynamics of fluid flow and the physical and chemical composition of groundwater It also gives an overview about the economic value of groundwater and its exploitation and use A consistent use of the internationally accepted SI units as well as the formula symbols in the text contributes to the understandability
