This book was released on 2020-12-10 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: La FAO ha promovido el enfoque ecosistémico de la pesca (EEP) como una aproximación holística dirigida a mejorar la situación crítica de la pesca a nivel mundial. A pesar de la amplia aceptación del EEP, se desconoce el grado en que la adopción de dicho marco condujo, en la práctica, a cambios reales en los sistemas de gestión. Esta publicación analiza siete pesquerías de América del Sur que intentaron desarrollar sistemas de manejo de acuerdo con principios básicos de un EEP: la vieira Zygochlamys patagonica y la anchoíta Engraulis anchoita en Argentina; el camarón siete barbas Xiphopenaeus kroyeri en Suriname; la almeja amarilla Mesodesma mactroides en Uruguay; el loco Concholepas concholepas en Chile; el pepino de mar Isostichopus fuscus en Ecuador; y la anchoveta Engraulis ringens en Perú. El análisis comparativo de estas pesquerías permitió identificar condiciones contextuales preexistentes propicias para el logro de pesquerías exitosas, incluyendo: (1) la presencia de límites del sistema pesquero bien definidos, con una clara correspondencia entre las escalas ecológica (recurso), de operación (pesca) y gestión (unidad de manejo); (2) fuerte cohesión interna, liderazgo y tradiciones en las comunidades pesqueras; (3) un marco legal adecuado para la implementación del EEP; y (4) condiciones institucionales propicias, tales como reglas de acceso bien definidas y gobernanza colaborativa entre los usuarios y los gobiernos centrales en el largo plazo. Los factores que desencadenaron cambios en el enfoque de gobernanza y que llevaron a sistemas de manejo más holísticos estuvieron relacionados, en la mayoría de los casos, a crisis pesqueras, aunque en otros casos el incentivo o factor disparador fuede naturaleza económica (e.g., certificación pesquera). Fue posible identificar logros relevantes como resultado de dichos cambios, que se vieron reflejados en los cuatro pilares de la sostenibilidad, i.e., ecológicos, sociales, económicos e institucionales. Se observaron efectos importantes de forzantes externos afectando a los sistemas pesqueros a diferentes escalas de espacio y tiempo, tales como el clima, los mercados, la acuicultura y la inestabilidad y fragilidad en los sistemas de gobernanza. Se describen estrategias de adaptación y mitigación para contender con estos impactos en diferentes etapas del ciclo de manejo, así como para aumentar la resiliencia de los sistemas pesqueros en el largo plazo.

This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Confronting Climate Uncertainty in Water Resources Planning and Project Design written by Patrick A. Ray and published by World Bank Publications. This book was released on 2015-08-20 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Confronting Climate Uncertainty in Water Resources Planning and Project Design describes an approach to facing two fundamental and unavoidable issues brought about by climate change uncertainty in water resources planning and project design. The first is a risk assessment problem. The second relates to risk management. This book provides background on the risks relevant in water systems planning, the different approaches to scenario definition in water system planning, and an introduction to the decision-scaling methodology upon which the decision tree is based. The decision tree is described as a scientifically defensible, repeatable, direct and clear method for demonstrating the robustness of a project to climate change. While applicable to all water resources projects, it allocates effort to projects in a way that is consistent with their potential sensitivity to climate risk. The process was designed to be hierarchical, with different stages or phases of analysis triggered based on the findings of the previous phase. An application example is provided followed by a descriptions of some of the tools available for decision making under uncertainty and methods available for climate risk management. The tool was designed for the World Bank but can be applicable in other scenarios where similar challenges arise.
Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
Download or read book The United Nations World Water Development Report 2020 written by UNESCO and published by . This book was released on 2020-03-27 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.
Download or read book Boundaries written by Christine E. Gudorf and published by Georgetown University Press. This book was released on 2010-04-15 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.
Download or read book Primates in Fragments written by Laura K. Marsh and published by Springer Science & Business Media. This book was released on 2013-09-07 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is number two in a series for Primates in Fragments. In this volume, ten years after the first http://www.springer.com/social+sciences/anthropology+%26+archaeology/book/978-0-306-47696-9, we continue to address issues regarding primates within a fractured landscape. There are seven sections based on specific categories of primates in fragments. In the Introductory section, authors discuss the issues surrounding primates in remnant habitats as well as encourage discussion about what we mean by fragmentation on a landscape scale. In the Long-Term and Regional Studies section, authors present information on changes that have occurred during longer studies as well as changes that have occurred over regions. In the Landscape, Metapopulations and the Matrix section, authors cover topics from dry to moist forests, and from metapopulations to single species use of multiple fragments locations. In Feeding and Behavioral Ecology, authors take a closer look at the flexibility and responsiveness of primates in fragments in terms of their food choices, resource use, and behavioral changes. In Endemic, Endangered, and Nocturnal Primates authors uncover details involving critical primates living in major city centers to the heights of the Himalayas. In Genetics, Disease and Parasites authors cover topics including population viability, disease and parasite transmission between primates in fragments and humans. Finally, in the Conservation and Ecology: Threats and Management section, we synthesize information in this volume and make recommendations for the future of work in this field and the survivability of primates in fragments.
Download or read book Tourism and Water written by Stefan Gössling and published by Channel View Publications. This book was released on 2015 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic and comprehensive guide to the current state of knowledge on tourism and water. It is the first book to thoroughly examine the interrelationships of tourism and water use based on global, regional and business perspectives. Its assessment of tourism's global impact along with its overviews of sectoral and management approaches will provide a benchmark by which the water sustainability of tourism will be measured for years to come. In making a clear case for greater awareness and enhanced water management in the tourism sector, it is hoped that the book will contribute to the wise and sustainable use of this critical resource. The book is interdisciplinary in coverage and international in scope. It is designed as essential reading for not only students of tourism but also practitioners.
Download or read book Primates in Fragments written by Laura K. Marsh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume was created initially from a symposium of the same name presented at the International Primatological Society's XVIII Congress in Adelaide. South Australia. 6-12 January 2000. Many of the authors who have contributed to this text could not attend the symposium. so this has become another vehicle for the rapidly growing discipline of Fragmentation Science among primatologists. Fragmentation has quickly become a field separate from general ecology. which underscores the severity of the situation since we as a planet are rapidly losing habitat of all types to human disturbance. Getting ecologists. particularly primatologists. to admit that they study in fragments is not easy. In the field of primatology. one studies many things. but rarely do those things (genetics. behavior. population dynamics) get called out as studies in fragmentation. For some reason "fragmentation primatologists" fear that our work is somehow "not as good" as those who study in continuous habitat. We worry that perhaps our subjects are not demonstrating as robust behaviors as they "should" given fragmented or disturbed habitat conditions. I had a colleague openly state that she did not work in fragmented forests. that she merely studied behavior when it was clear that her study sites. everyone of them. was isolated habitat. Our desire to be just another link in the data chain for wild primates is so strong that it makes us deny what kinds of habitats we are working in. However.
Download or read book Sustainable Tourism V written by F. D. Pineda and published by WIT Press. This book was released on 2012 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tourism has become a major international industry, with many countries all over the world relying on the income it produces. Its economic advantages as a major source of finance and employment leads to its active promotion by governments and other institutions, independent of the consequences on the environment, ecology and social structure of affected regions.Conference topics include the following; Tourism strategies; Tourism as a tool of development; Emergent strategies for tourism development; Environmental issues; Climate change and effects of natural hazards in tourism; Tourism and protected areas; Art, architecture and culture; Rural tourism; Modelling; Community involvement; Tourism and the built environment; Renovation of mature destinations; heritage tourism; medical tourism.Sustainable Tourism 2012 will adopt a multi-disciplinary approach and will aim specifically to foster greater understanding and collaboration between scientists and social science experts, practitioners and policy makers. It will take a broad view of this sophisticated and complex industry, and will examine the practice of sustainable tourism from global travel trends through to destination and site management. Innovative solutions, including those involving ecological tourism are particularly welcome, as well as cultural initiatives that will lead to better approaches to tourism with the objective of preserving the diversity of our planet.
