This volume explores the encounter between two processes that are unfolding in diverse patterns across Asia-the rapid urbanization of Asia across big cities, smaller towns, and the newest urban concentrations; and the contentious debates and novel schemes by which nature is figured and emplaced in cities and their conurbations. Contemporary Asian cities displace nature by causing its death and withering, but also embrace it through acts of renewal and the pursuit of sustainability. Contributors to this volume gather case studies from across Asia to address projects of urban greening and reimagining nature in urban life. The book illustrates how the intersection of urban growth and urban nature is a place rich with fresh ideas about urban planning, governance, and social life.

The current report reviews existing policies for energy sustainability in Bulgaria and the EU, the main achievements and challenges in their implementation, and discusses the central issues to Bulgaria's sustainable development agenda. The report presents a summary of the transition to sustainable development in Bulgaria, and offers policy recommendations for improving the governance of the Bulgarian green energy sector. Achieving security, sustainability, and competitiveness in the energy sector is a daunting task for a union of twenty-seven states, especially since the issue of securing the supply of energy has traditionally been a national matter. In their drive to reach climate change and energy targets during the past decade, European governments have utilized quick fix solutions like turning to nuclear power or replacing coal with gas, thus burdening future generations with nuclear waste disposal and increasing EU's energy dependence on Russia. Yet, two major events - the gas crisis of January 2009 and the Fukusima nuclear disaster of March 2011 - have reshaped the thinking and rekindled the debate on the ways of achieving energy security and stability of supply in Europe.

"This book is a good reference book for city planners, architects and civil engineers involved in the conceptualisation, design and building of urban habitations, who aspire to increase the liveability of their cities. It introduces the Singapore Green Plot Ratio (GnPR) as an Urban Planning Metric to promote the widespread and intensive use of greenery for new and existing buildings in towns and cities like Singapore - a former third world city that has transformed into one of the world's most liveable metropolises. Increasing urban greenery has been observed to enhance the quality of our built environment, and in turn, the quality of life of its inhabitants. The book shows readers how to do so using the GnPR, which it presents as an important urban complement of the leaf area ratio (LAI) concept, through an in-depth discussion of three key aspects of the GnPR. It proposes optimal levels of GnPR for various land-use types and how these levels are benchmarked against current levels of greenery provision; stipulates the greenery quantum which encourages the concentration of some plants, especially native trees and certain local species; and advocates the development of ecological or natural landscapes over manicured gardens. The book also discusses the impact of various levels of GnPR provision with the inevitable capital and maintenance costs of greening built environments, and how they affect the application of the GnPR guidelines"--Publisher's website.

How does nature work in our human-created city, suburb, and exurb/peri-urb? Indeed how is ecology - including its urban water, soil, air, plant, and animal foundations - spatially entwined with this great human enterprise? And how can we improve urban areas for both nature and people? Urban Ecology: Science of Cities explores the entire urban area: from streets, lawns, and parks to riversides, sewer systems, and industrial sites. The book presents models, patterns, and examples from hundreds of cities worldwide. Numerous illustrations enrich the presentation. Cities are analyzed, not as ecologically bad or good, but as places with concentrated rather than dispersed people. Urban ecology principles, traditionally adapted from natural-area ecology, now increasingly emerge from the distinctive features of cities. Spatial patterns and flows, linking organisms, built structures, and the physical environment highlight a treasure chest of useful principles. This pioneering interdisciplinary book opens up frontiers of insight, as a valuable source and text for undergraduates, graduates, researchers, professionals and others with a thirst for solutions to growing urban problems.
