This book was released on 2017-10-18. Urban Soils available in PDF, EPUB and Kindle. 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 book was released on 1999-03-25. Urban Soils available in PDF, EPUB and Kindle. The soil which is found in large cities offer distinctive challenges to the landscape architect or horticulturist responsible for maintaining these urban plantings. Often compacted, contaminated, or otherwise unsuitable for use in major landscape projects, these soils require practical methods which can insure a successful outcome of a landscape project. This applications-oriented, introductory reference addresses numerous topics in the field of urban soil science.

Download and read online ebook Forest and Rangeland Soils of the United States Under Changing Conditions write by Richard V. Pouyat. This book was released on 2020-09-02. Forest and Rangeland Soils of the United States Under Changing Conditions available in PDF, EPUB and Kindle. This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.

Download and read online ebook Contaminated Urban Soils write by Helmut Meuser. This book was released on 2010-07-23. Contaminated Urban Soils available in PDF, EPUB and Kindle. 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.
Understanding Soils in Urban Environments

Download and read online ebook Understanding Soils in Urban Environments write by Pam Hazelton. This book was released on 2021-11-01. Understanding Soils in Urban Environments available in PDF, EPUB and Kindle. With an ever-increasing proportion of the world’s population living in cities, soil properties such as salinity, acidity, water retention, erosion and pollution are becoming more significant in urban areas. While these are known issues for agriculture and forestry, as urban development increases, it is essential to recognise the potential of soil properties to create problems for the environment as well as structural concerns for buildings and other engineering works. Understanding Soils in Urban Environments explains how urban soils develop, change and erode. It describes their physical and chemical properties with a focus on specific soil problems that cause environmental damage, such as acid sulfate soils, and also affect the integrity of engineering structural works. This fully revised second edition addresses contemporary issues, including an increase in the use of green roofs and urban green space as well as manufactured soils in a variety of urban environments. Understanding Soils in Urban Environments provides a concise introduction to all aspects of soils in urban environments and will be extremely useful to students in a wide range of disciplines, from soil science and urban forestry and horticulture, to planning, engineering, construction and land remediation, as well as to engineers, builders, landscape architects, ecologists, planners and developers.
