Download or read book Discontinuities in Ecosystems and Other Complex Systems written by Craig R. Allen and published by Columbia University Press. This book was released on 2008 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the publication of C. S. Holling's seminal work on the relationship between animal body mass patterns and scale-specific landscape structure, ecologists began to explore the theoretical and applied consequences of discontinuities in ecosystems and other complex systems. Are ecosystems and their components continuously distributed and do they adhere to scaling laws, or are they discontinuous and more complex than early models would have us believe? The resulting propositions over the structure of complex systems sparked an ongoing debate regarding the mechanisms generating discontinuities and the statistical methods used for their detection. This volume takes the view that ecosystems and other complex systems are inherently discontinuous and that such fields as ecology, economics, and urban studies greatly benefit from this paradigm shift. Contributors present evidence of the ubiquity of discontinuous distributions in ecological and social systems and how their analysis provides insight into complex phenomena. The book is divided into three sections. The first focuses on background material and contrasting views concerning the discontinuous organization of complex systems. The second discusses discontinuous patterns detected in a number of different systems and methods for detecting them, and the third touches on the potential significance of discontinuities in complex systems. Science is still dominated by a focus on power laws, but the contributors to this volume are convinced power laws often mask the interesting dynamics of systems and that those dynamics are best revealed by investigating deviations from assumed power law distributions. In 2008, a grand conference on resilience was held in Stockholm, hosting 600 participants from around the world. There are now three big centers established with resilience, the most recent one being the Stockholm Resilience Center, with others in Australia (an international coral reef center), Arizona State University's new sustainability center focusing on anthropology, and Canada's emerging social sciences and resilience center. Activity continues to flourish in Alaska, South Africa, and the Untied Kingdom, and a new center is forming in Uruguay.

Download or read book International and Transnational Perspectives on Urban Systems written by Celine Rozenblat and published by Springer. This book was released on 2018-05-08 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the recent evolutions of cities in the world according to entirely revised theoretical fundamentals of urban systems. It relies on a vision of cities sharing common dynamic features as co-evolving entities in complex systems. Systems of cities that are interdependent in their evolutions are characterized in the context of that dynamics. They are identified on various geographical scales—worldwide, regional, or national. Each system exhibits peculiarities that are related to its demographic, economic, and geopolitical history, and that are underlined by the systematic comparison of continental and regional urban systems, following a common template throughout the book. Multi-scale urban processes, whether local (one city), or within national systems (systems of cities), or linked to the expansion of transnational networks (towards global urban systems) throughout the world over the period 1950–2010 are deeply analyzed in 16 chapters. This global overview challenges urban governance for designing policies facing globalization and the subsequent ecological transition. The answers, which emerge from the diversity of situations in the world, add some reflections on and recommendations to the “urban system framework” proposed in the Habitat III agenda.
Download or read book Growing Populations Changing Landscapes written by National Academy of Sciences and published by National Academies Press. This book was released on 2001-06-12 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world's population exceeds an incredible 6 billion people, governmentsâ€"and scientistsâ€"everywhere are concerned about the prospects for sustainable development. The science academies of the three most populous countries have joined forces in an unprecedented effort to understand the linkage between population growth and land-use change, and its implications for the future. By examining six sites ranging from agricultural to intensely urban to areas in transition, the multinational study panel asks how population growth and consumption directly cause land-use change, and explore the general nature of the forces driving the transformations. Growing Populations, Changing Landscapes explains how disparate government policies with unintended consequences and globalization effects that link local land-use changes to consumption patterns and labor policies in distant countries can be far more influential than simple numerical population increases. Recognizing the importance of these linkages can be a significant step toward more effective environmental management.
Download or read book Grand Challenges in Environmental Sciences written by National Research Council and published by National Academies Press. This book was released on 2001-05-24 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists have long sought to unravel the fundamental mysteries of the land, life, water, and air that surround us. But as the consequences of humanity's impact on the planet become increasingly evident, governments are realizing the critical importance of understanding these environmental systemsâ€"and investing billions of dollars in research to do so. To identify high-priority environmental science projects, Grand Challenges in Environmental Sciences explores the most important areas of research for the next generation. The book's goal is not to list the world's biggest environmental problems. Rather it is to determine areas of opportunity thatâ€"with a concerted investmentâ€"could yield significant new findings. Nominations for environmental science's "grand" challenges were solicited from thousands of scientists worldwide. Based on their responses, eight major areas of focus were identifiedâ€"areas that offer the potential for a major scientific breakthrough of practical importance to humankind, and that are feasible if given major new funding. The book further pinpoints four areas for immediate action and investment.

Download or read book Urban Climates written by T. R. Oke and published by Cambridge University Press. This book was released on 2017-09-14 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
Download or read book Chicago Made written by Robert Lewis and published by University of Chicago Press. This book was released on 2009-05-15 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the lumberyards and meatpacking factories of the Southwest Side to the industrial suburbs that arose near Lake Calumet at the turn of the twentieth century, manufacturing districts shaped Chicago’s character and laid the groundwork for its transformation into a sprawling metropolis. Approaching Chicago’s story as a reflection of America’s industrial history between the Civil War and World War II, Chicago Made explores not only the well-documented workings of centrally located city factories but also the overlooked suburbanization of manufacturing and its profound effect on the metropolitan landscape. Robert Lewis documents how manufacturers, attracted to greenfield sites on the city’s outskirts, began to build factory districts there with the help of an intricate network of railroad owners, real estate developers, financiers, and wholesalers. These immense networks of social ties, organizational memberships, and financial relationships were ultimately more consequential, Lewis demonstrates, than any individual achievement. Beyond simply giving Chicago businesses competitive advantages, they transformed the economic geography of the region. Tracing these transformations across seventy-five years, Chicago Made establishes a broad new foundation for our understanding of urban industrial America.
