This collection breaks new ground by investigating applications of degrowth in a range of geographic, practical and theoretical contexts along the food chain. Degrowth challenges growth and advocates for everyday practices that limit socio-metabolic energy and material flows within planetary constraints. As such, the editors intend to map possibilities for food for degrowth to become established as a field of study. International contributors offer a range of examples and possibilities to develop more sustainable, localised, resilient and healthy food systems using degrowth principles of sufficiency, frugal abundance, security, autonomy and conviviality. Chapters are clustered in parts that critically examine food for degrowth in spheres of the household, collectives, networks, and narratives of broader activism and discourses. Themes include broadening and deepening concepts of care in food provisioning and social contexts; critically applying appropriate technologies; appreciating and integrating indigenous perspectives; challenging notions of 'waste', 'circular economies' and commodification; and addressing the ever-present impacts of market logic framed by growth. This book will be of greatest interest to students and scholars of critical food studies, sustainability studies, urban political ecology, geography, environmental studies such as environmental sociology, anthropology, ethnography, ecological economics and urban design and planning.

Sustainable Development has become the leading concept of the 21 century. It describes a development, which agrees with the needs of the present generation but does not endanger the chances of the coming generations to satisfy also their needs. "Sustainable development" has become an important general goal for all fields of life like economy, ecology and social balance. The development and shaping of our future has been discussed internationally like on the summits of the Conferences in Rio and in Johannesburg. But this is also a topic on national base in various countries. Leading authorities in various fields of economy and politics have also accepted this concept. Although the concept of sustainable development has been generally accepted, there are still problems how to achieve and evaluate these general goals. It is clear that the definitions about the prime needs vary from man to man, from country to country and from continent to continent. But pollution does not respect national borders. Therefore, it is necessary to develop the politics of economy, ecology and social demands by a synergistic way that they are strengthened by each other. If it is not possible to stop tendencies, which threaten the future quality of life, the cost demands of societies will dramatically increase and negative tendencies will become irreversible.

This book investigates the complex and unpredictable temporalities of waste. Reflecting on waste in the context of sustainability, materiality, social practices, subjectivity and environmental challenges, the book covers a wide range of settings, from the municipal garbage crisis in Beirut, to food rescue campaigns in Hong Kong and the toxic by-products of computer chip production in Silicon Valley. Waste is one of the most pressing issues of the day, central to environmental challenges and the development of healthier and more sustainable futures. The emergence of the new field of discard studies, in addition to expanding research across other disciplines within the social sciences, is testament to the centrality of waste as a crucial social, material and cultural problem and to the need for multi- and transdisciplinary approaches like those provided in this volume. This edited collection seeks to develop a framework that understands the material properties of different kinds of waste, not as fixed, stable or singular but asdynamic, relational and often invisible. It brings together new and cutting-edge research on the temporalities of waste by a diverse range of international authors. Collectively, this research presents a persuasive argument about the need to give more credence to the capacities of waste to provoke us in materially and temporally complex ways, especially those substances that complicate our understandings of life as bounded duration. This book will be of great interest to students and scholars of the environmental humanities, cultural studies, anthropology and human geography.

Waste is everywhere. It’s clogging our rivers and littering our streets. The Pacific Ocean contains a great garbage patch three times the size of France. Our junk is even orbiting the earth. No wonder there are microplastics in our bloodstreams.

Waste, a problem we’ve ignored for too long, is now a global crisis – and it’s getting worse.

From the landfills of New Delhi, to the second-hand clothing markets of Ghana and the overflowing sewers of Britain, join Oliver Franklin-Wallis as he reveals the dirty truth about the global waste industry.

In this eye-opening and ultimately hopeful book, he meets some of the heroic people trying to make a difference and explains precisely how we can create a better, less wasteful world.

The state of the art in the area of security related civil science and technology concerning energetic materials and munitions is of pressing importance at the present time, because 10 years after the end of the cold war, in many countries in east and west, huge stockpiles of munitions still await destruction. The safety behavior of munitions and their energetic material is the determining factor for all precautionary measures for the protection of environment and population. The probability of a catastrophic reaction of munitions and their energetic components will be so more likely, the closer the munitions are to the end of their life time. Residues and undetected ordnance, recycling, destruction of ammunition and depletion or reuse of energetic materials will either cause more or less damage to environment. Scientific research and development have the aim to increase performance of munitions on one side and to improve safety in relation to unpredictable events on the other side. The impact on the environment by the production and normal use of munitions and their residues after use will acquire an increasing importance in environmental awareness. The excellent technical presentations were classified in five Groups, according to the technical programme. The "Introduction to the subject; Methods, tests and application; Insensitive and "green" munitions; Storage and transportation; and Demilitarisation and recycling" sessions, were closed by a final and general interesting discussion among participants.

Construction and Demolition Waste (CDW), from the construction, maintenance, renovation and demolition of buildings and structures, represents a large proportion of the waste in industrialized societies. Compared to other forms, such as household waste, more than 90% of CDW can be used as a resource and a substitute for construction materials, especially for primary, natural raw materials. Reuse, recovery and recycling depends on the quality and market for the materials, and the environmental impact of the processes for conversion of CDW from old structures to its use in new structures. However, the utilization today of CDW products as secondary resources is marginal. Most CDW is deposited or used as fill material, and the opportunities of high quality recycling are generally neglected. This book presents the opportunities for the sustainable and resource efficient utilisation of CDW, focusing on recycling of concrete and masonry as the major forms of CDW. The recycling of gypsum, timber, mineral wool, asphalt and other types are also described. Its aim is to present a chain of value and material streams in the transformation of obsolete buildings and structures into new buildings and structures. It takes a holistic view, focusing on the lifecycle economy (the circular economy) and integrated management aspects of various scenarios ranging from high industrial urban renewal to debris removal and management after disasters and conflicts. It is based on the authors 35 years of research and development combined with practical international experience within the demolition and recycling area. It addresses students, architects, civil engineers, building owners, public authorities and others working in urban planning, demolition and resource management in the building and construction sector and in the reconstruction of damaged buildings after disasters and wars.

The Observational Method (OM) is a natural and powerful technique that maximises economy while assuring safety. Its key features are highlighted in The Observational Method in Civil Engineering through twelve case histories from major infrastructure projects. They cover protection of adjacent structures including buildings and railway systems, bored and jacked tunnels, shafts and cofferdams, retaining walls, embankments, deep foundations, ground improvement and groundwater control. They illustrate how the OM can achieve more effective collaboration between the client and the design and construction teams, as well as how it can enhance the industry's ability to learn from experience, thus improving future practice and stimulating innovation. Despite these advantages, the OM is significantly underused. The book demonstrates how the full potential of the OM can overcome a wide range of concerns and constraints. Other chapters address the advantages and limitations of the OM, the key role of progressive modification, the art of achieving agreement and the commercial and contractual environment. The book will appeal to a range of construction professionals, including civil, structural and geotechnical engineers, contractors and owners. It will also be of interest to students and researchers.
