With more than 50% of the world’s population already living in towns and cities, migration from rural areas continuing at an alarming rate in developing countries and suburbanisation using more and more land in developed countries, the urban environment has become supremely important with regard to human health and wellbeing. For centuries, urbanisation has caused relatively low level soil conta- nation mainly by various wastes. However, from the time of the Industrial Revolution onwards, both the scale of urban development and the degree of soil contamination rapidly increased and involved an ever widening spectrum of c- taminants. With constraints on the supply of land for new urban development in many countries, it is becoming increasingly necessary to re-use previously dev- oped (brownfield) sites and to deal with their accompanying suites of contaminants. It is therefore essential to fully understand the diversity and properties of urban soils, to assess the possible risks from the contaminants they contain and devise ways of cleaning up sites and/or minimizing hazards. The author, Helmut Meuser, is Professor of Soil Protection and Soil Clean-up at the University of Applied Sciences, Osnabrück and is one of Europe’s foremost experts on contamination from technogenic materials in urban soils. He has many years’ experience of research in Berlin, Essen, Osnabrück, other regions of Germany, and several other countries.

Globally, 30% of the world population lived in urban areas in 1950, 54% in 2016 and 66% projected by 2050. The most urbanized regions include North America, Latin America, and Europe. Urban encroachment depletes soil carbon and the aboveground biomass carbon pools, enhancing the flux of carbon from soil and vegetation into the atmosphere. Thus, urbanization has exacerbated ecological and environmental problems. Urban soils are composed of geological material that has been drastically disturbed by anthropogenic activities and compromised their role in the production of food, aesthetics of residential areas, and pollutant dynamics. Properties of urban soils are normally not favorable to plant growth—the soils are contaminated by heavy metals and are compacted and sealed. Therefore, the quality of urban soils must be restored to make use of this valuable resource for delivery of essential ecosystem services (e.g., food, water and air quality, carbon sequestration, temperature moderation, biodiversity). Part of the Advances in Soil Sciences Series, Urban Soils explains properties of urban soils; assesses the effects of urbanization on the cycling of carbon, nitrogen, and water and the impacts of management of urban soils, soil restoration, urban agriculture, and food security; evaluates ecosystem services provisioned by urban soils, and describes synthetic and artificial soils.

This textbook addresses the increasing trend in urbanization of the world’s population and its relation with urban soils. Written by active practitioners of university level teaching and research, this book is designed primarily as an educational text, while it also provides readers with an authoritative gateway to the primary literature. It includes explicit coverage of spatial and statistical (multivariate) techniques and case studies to illustrate key concept, and to support practical guidance in issues such as data collection and analysis. The authors reflect current developments in research and urban trends. In China, for example, the proportion of the population living in cities increased from 13% in 1950 to 45% in 2010 (World Bank data). Australia is one of the world's top ten urbanised countries with population greater than ten million, with approximately 90% of its population living in cities, mainly along Australia's coast. The most rapidly urbanising populations are currently in nations of the African continent. Soils in urban areas have multiple functions which are becoming more valued by urban communities: soils supply water, nutrients and physical support for urban plant and animal communities (parks, reserves, gardens), and are becoming increasingly valued for growing food. Soils may be used for building foundations, or as building materials themselves. Urban hydrology relies on the existence of unsealed soils for aquifer protection and flood control. This volume presents the importance of urban ecosystems and the impacts of global change. It examines pedogenesis of urban soils: natural materials affected by urban phenomena, and natural processes acting on urban materials, including an examination of different climatic zones. There is a focus on soils formed on landfill, reclaimed land, dredge spoils as well as soil-related changes in urban geomorphology. There is plenty of discussion on urban soil as a source and sink as well as soil geochemistry and health. The book is intended primarily as a text for upper-level undergraduate, and postgraduate (Masters) students. It will also be invaluable as a resource for professionals such as researchers, environmental regulators, and environmental consultants.

Presents essential information on the fundamental properties of soils and how they are affected under urban conditions. Coverage includes the physical, chemical and biological characterisitics of soil; how it can be classified, inventoried and mapped; urban soil properties; problems and solutions to many of the more common urban soils; methods of ameliorating compaction including other major drainage problems and much more. Contains over 150 illustrations.

This edited book, Soil Contamination - Threats and Sustainable Solutions, is intended to provide an update on different aspects of soil contamination exerted by a multiplicity of exogenous and endogenous causes. We hope that this book will continue to increase information from diverse sources and to give some real-life examples, extending the appreciation of the complexity of this subject in a way that may stimulate new approaches in relevant fields.

Following a description of the various sources and factors influencing the contents of heavy metal pollution in post-catastrophic and agricultural soils, subsequent chapters examine soil enzymes and eggs as bio-monitors, lead adsorption, the effects of arsenic on microbial diversity, and the effects of Mediterranean grasslands on abandoned mines. A third section focuses on the adaptation strategies used by plants and bacteria, such as Pinus sylvestris in industrial areas, and the rhizosphere in contaminated tropical soils and soil treated with sewage sludge. Further topics addressed include strategies of bioremediation, e.g. using transgenic plants as tools for soil remediation. This new volume on heavy metals in soil will be of interest to researchers and scholars in microbial and plant biotechnology, agriculture, the environmental sciences and soil ecology.

Inorganic Contaminants and Radionuclides is a single reference covering common inorganic contaminants in detail, including their distribution in the environment, challenges linked to management, geogenic sources, anthropogenic sources, exposure and effects, international agreements and legislation relating to the contaminant, remediation options and global case studies. In addition, the book provides summaries of contaminated sites and key details about contaminants to present a more comprehensive understanding and improve remediation and management practices. The book's clear, consistent organization makes it a valuable resource for researchers, students and practitioners working in environmental science, environmental management and environmental engineering.One of the major constraints to assessing and remediating contaminated sites is the lack of awareness of the extent and severity of contaminated sites amongst the community, regulators, policymakers, industry operators, university graduates and environmental managers. This book helps to manage these constraints. - Provides a one-stop reference on the nature and properties of inorganic contaminants, including a transdisciplinary approach to managing contaminated sites - Includes global case studies covering contaminated site assessment, management and remediation - Presents in-depth research and data on specific contaminants, with a separate chapter for each contaminant

Against the background of unprecedented rates of urbanisation in the Global South, leading to massive social, economic and environmental transformations, this book engages with the dire need to understand the ecology of such settings as the foundation for fostering sustainable and resilient human settlements in contexts that are very different to the Global North. It does so by bringing together scholars from around the world, drawing together research and case studies from across the Global South to illustrate, in an interdisciplinary and comprehensive fashion, the ecology of towns and cities in the Global South. Framed using a social-ecological systems lens, it provides the reader with an in-depth analysis and understanding of the ecological dynamics and ecosystem services and disservices within the complex and rapidly changing towns and cities of the Global South, a region with currently scarce representation in most of the urban ecology literature. As such the book makes a call for greater geographical balance in urban ecology research leading towards a more global understanding and frameworks. The book embraces the complexity of these rapid transformations for ecological and environmental management and how the ecosystems and the benefits they provide shape local ecologies, livelihood opportunities and human wellbeing, and how such knowledge can be mobilised towards improved urban design and management and thus urban sustainability.
