Coastal Zones and Estuaries

Autor: Federico Ignacio Isla

Número de Páginas: 536

Coastal Zones and Estuaries is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources which is part of the global Encyclopedia of Life Support Systems (EOLSS), an integrated compendium of twenty one Encyclopedias. The Theme deals with important links of water, sediment, and nutrients between continents and oceans. The present behavior of sea level, ice sheets, and coral reefs is still a matter of controversy and concern. Coastal experiences learned in developed countries should be used to improve coastal policies world wide. Within the Global Change Programme, it is recognized that the earth system is characterized by critical limits and abrupt changes. The coastal systems are particularly sensitive to these changes. This volume is aimed at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Pollution of Water Bodies in Latin America

Autor: Leobardo Manuel Gómez-oliván

Número de Páginas: 367

The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

Lagoon Environments Around the World

Autor: Andrew James Manning

Número de Páginas: 247

Lagoon Environments Around the World - A Scientific Perspective covers a wide range of topics. Typically bordering between land and sea, lagoons are among the most diversely utilized waterways on the planet. Lagoons are extremely important environments socio-economically, and their usage places ever increasing stress on these very sensitive aquatic regions. The effective management of shallow aquatic environments requires a detailed scientific understanding of the various contributary natural processes. This has both environmental and economic implications, especially where there is any anthropogenic involvement. This book draws on international scientific research to examine the following lagoon related issues: classification, circulation hydrodynamics, ecosystems, sedimentation, anthropogenic stresses, and response to extreme events. The research was carried out by researchers who specialize in shallow water processes and related issues.

Monitoring of Marine Pollution

Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.

Environmental Assessment of Patagonia's Water Resources

Autor: Américo Iadran Torres , Verena Agustina Campodonico

Número de Páginas: 354

This book presents contributions devoted to the hydrogeochemical characterization of aquatic environments of Patagonia, including those of Ushuaia city, known as "The southernmost city in the world". Patagonia (between 39° and 55° S) is located in southern South America. Eight main river systems pour their waters into the SW Atlantic Ocean. Rivers, with their headwaters mainly located in the Andes, supply dissolved and particulate matter to the coastal zone, as well as nutrients, which benefit biological communities. Besides, freshwater in this region with little anthropogenic impact supports human life and a high wildlife biodiversity. Unfortunately, the recent increase in human activities, such as the use of fertilizers, wastewater discharges, extensive deforestation and dam construction, is affecting the quality and quantity of water resources. The book is of interest for researchers, professors and government agencies that decide on water resources management policies.

Coastal and Deep Ocean Pollution

Autor: Andres Hugo Arias , Sandra Elizabeth Botte

Número de Páginas: 326

During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

Widening the Scope of Environmental Policies in North America

Autor: Gustavo Sosa-nunez

Número de Páginas: 236

This edited volume provides a variety of insights into the context in which ocean and wetlands policy is placed at the sub-continental level. The governments of Mexico, Canada, and United States of America have recognized the importance of conserving, protecting, and enhancing the environment in their territories. As a result, they have developed an institutional structure aimed at furthering environmental cooperation. However, marine environment has played a secondary role, characterized by scientific cooperation that does not develop into regional policies. This project analyzes how ocean and wetlands preservation is omitted from the North American Agreement on Environmental Cooperation, meaning that collaborative efforts under-perform or remain largely sidelined from mainstream issues. As contributors come from a mix of the social and natural sciences (politics, international relations, law studies, sociology, oceanology, and oceanography), this book presents diverse viewpoints on how to address wetlands protection, deep ocean research collaboration, and the marine context of the Sustainable Development Goals.

Mexico: Un Experimento

Autor: Jalil Saab H.

Número de Páginas: 299

Para entender al hombre del siglo XXI, no se debera seleccionar como modelo a un pais desarrollado con menos del 20% de la humanidad; pero tampoco a una nacion marginada. Debera buscar un lugar donde los flujos modernos y antiguos se encuentren, donde los avances tecnologicos se enfrenten con carencias ancestrales, las experiencias historicas y culturales se aglutinen, donde convivan agricultores primitivos y ejecutivos bursatiles. Este trabajo esta dividido en dos partes. La primera esboza los origenes de la civilizacion occidental y su implantacion en Mexico a lo largo de su historia: desde el mundo prehispanico hasta la finales del siglo XX, todo ello en forma desmistificada e iconoclasta. La segunda parte analiza las vivencias de aquellas generaciones posteriores a la Segunda Guerra Mundial: los posnucleares. Esta ultima intenta condensar las corrientes filosoficas, economicas, politicas y sociales producto de la evolucion cientifica y tecnologica de nuestros dias
