The governance of natural resources used by many individuals in common is an issue of increasing concern to policy analysts. Both state control and privatization of resources have been advocated, but neither the state nor the market have been uniformly successful in solving common pool resource problems. After critiquing the foundations of policy analysis as applied to natural resources, Elinor Ostrom here provides a unique body of empirical data to explore conditions under which common pool resource problems have been satisfactorily or unsatisfactorily solved. Dr Ostrom uses institutional analysis to explore different ways - both successful and unsuccessful - of governing the commons. In contrast to the proposition of the 'tragedy of the commons' argument, common pool problems sometimes are solved by voluntary organizations rather than by a coercive state. Among the cases considered are communal tenure in meadows and forests, irrigation communities and other water rights

Un libro que es preciso conocer ya que aborda uno de los problemas más graves que produjo el siglo XX: la contaminación que sufre la Tierra.Primavera silenciosa (1962), de la bióloga marina y zoóloga estadounidense Rachel Louise Carson (1907-1964), es un libro que es preciso conocer ya que aborda uno de los problemas mas graves que produjo el siglo XX: la contaminacion que sufre la Tierra. Utilizando un lenguaje transparente, el rigor propio del mejor analisis cientifico y ejemplos estremecedores, Carson denuncio los efectos nocivos que para la naturaleza tenia el empleo masivo de productos quimicos como los pesticidas, el DDT en particular. Se trata, por consiguiente, de un libro de ciencia que va mas alla del universo cientifico para adentrarse en el turbulento mundo de "lo social". Su trascendencia fue tal que hoy esta considerado uno de los principales responsables de la aparicion de los movimientos ecologistas a favor de la conservacion de la naturaleza. De hecho,Primavera silenciosa consiguio lo que pocos textos cientificos logran: iluminar nuestros conocimientos de procesos que tienen lugar en la naturaleza y despertar el interes de la sociedad tanto por la ciencia que es necesaria para comprender lo que sucede en nuestro planeta, como por la situacion presente y futura de la vida que existe en el.

This is an updated version of the best selling first edition, Ecological Census Techniques, with updating, some new chapters and authors. Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

El procedimiento de Evaluación de Impacto Ambiental es una de las mejores herramientas preventivas de las que disponemos para proteger y conservar nuestro medio ambiente. En él, intervienen numerosos actores cuyos cometidos son muy variados, por lo que en este libro trataremos de esclarecer las funciones de todos los implicados.Los estudios de Impacto Ambiental se realizan con el objetivo de predecir y evitar los posibles impactos ambientales derivados de la ejecucion de proyectos.

Por ello, a lo largo del presente libro, trataremos de aclarar todos estos conceptos.A lo largo de la obra, se abordaran, desde una perspectiva practica y a traves de numerosos ejemplos, los contenidos que deben formar parte de un Estudio de Impacto Ambiental, haciendo hincapie en el establecimiento de medidas preventivas, correctoras y compensatorias.Por ultimo, se tratara de pormenorizadamente el caso concreto de los Estudios de Impacto Ambiental de parques eolicos, de gran actualidad, para que el se proponen medidas de minimizacion especificas."

Although the Artic has traditionally been regarded as a remote and secondary region in the shaping and evolution of the global power balances, Vicente López-Ibor Mayor, Luis Francisco Martínez Montes and Emilio Sanchez de Rojas Diaz set the record straight on this misconception is concerned and analyse the role that the zone has played throughout history: a far from insignificant function in the strategy of the major powers since the beginnings of the Modern Era. They also review Spain''s virtually fogotten, but by no means less fascinating, past involvement in the Artic (or rather peri-Artic).The perspective of these experts on the subject matter give some insight into the place that the Artic, as a consequence of its position and its resources, always had, hypothetically or in reality, and will very probably have in the international geopolitics of 21st Century.These three experts also give careful consideration to the Artic''s present and future, reviewing its constantly changing geopolitical role, the energy factor, the geoeconomics, the security and the conflicts, as well as its view from an International Law perspective.

While a broad spectrum of environmental threats has made its entry into contemporary literary studies during the past decades, the range of environment-related diseases in creative writing has often escaped the attention of literary critics, waiting still to be unearthed. In this new geologic epoch, the Anthropocene, the editors of this collection take up a new angle on environmental humanities, and attempt to highlight the impact of global environmental degradation on public health that a number of literary texts make visible. In the wake of the global interest in the connection between environmental degradation and human health disruption, the eleven essayists in this volume bring to the fore a central question for the environmental humanities today: How immersed should the literary scholar be in his/her explorations of human health issues, and how will new work in the field affect environmental criticism in America and elsewhere? This collection demonstrates that already significant contributions are being made by American writers on the topic of environment-related diseases.
