Download or read book Carbon Sequestration in Urban Ecosystems written by Rattan Lal and published by Springer Science & Business Media. This book was released on 2011-12-10 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

Download or read book Sowing Seeds in the City written by Elizabeth Hodges Snyder and published by Springer. This book was released on 2016-05-20 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: A majority of the world’s population lives in cities. Urban areas have largely been disconnected from the processes associated with producing food. A broad range of community efforts have emerged to reconnect people in urban areas to fresh foods with expected benefits for public health. These efforts can be found in cities across the country and cross both economic and ethnic lines. They have been led by the non- scientific community and are best characterized as social movements. Expansion of agriculture to non- traditional areas including community or kitchen gardens in urban or peri- urban environments has the potential to provide a range of ecosystem services as well as reduce stressors on non- urban environments. These services/benefits include improved public health, improved human nutrition and diet, large-scale production of renewable resources, increased food security with less resilience on traditional agricultural landscapes and seascapes, enhanced ecosystem function in urban areas, and increased public appreciation for and understanding of ecosystem services. ​

Download or read book Human and Ecological Risk Assessment written by Dennis J. Paustenbach and published by John Wiley & Sons. This book was released on 2017-05-22 with total page 1476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human and Ecological Risk Assessment: Theory and Practice assembles the expertise of more than fifty authorities from fifteen different fields, forming a comprehensive reference and textbook on risk assessment. Containing two dozen case studies of environmental or human health risk assessments, the text not only presents the theoretical underpinnings of the discipline, but also serves as a complete handbook and "how-to" guide for individuals conducting or interpreting risk assessments. In addition, more than 4,000 published papers and books in the field are cited. Editor Dennis Paustenbach has assembled chapters that present the most current methods for conducting hazard identification, dose-response and exposure assessment, and risk characterization components for risk assessments of any chemical hazard to humans or wildlife (fish, birds, and terrestrials). Topics addressed include hazards posed by: Air emissions Radiological hazards Contaminated soil and foods Agricultural hazards Occupational hazards Consumer products and water Hazardous waste sites Contaminated air and water The bringing together of so many of the world's authorities on these topics, plus the comprehensive nature of the text, promises to make Human and Ecological Risk Assessment the text against which others will be measured in the coming years.

Download or read book Risk Based Waste Classification in California written by National Research Council and published by National Academies Press. This book was released on 1999-07-14 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Toxic Substances Control (DTSC) of the State of California Environmental Protection Agency is in the process of complying with the Regulatory Structure Update. The Regulatory Structure Update is a comprehensive review and refocusing of California's system for identifying and regulating management of hazardous wastes. As part of this effort, the DTSC proposes to change its current waste classification system that categorizes wastes as hazardous or nonhazardous based on their toxicity. Under the proposed system there would be two risk-based thresholds rather than the single toxicity threshold currently used to distinguish between the wastes. Wastes that contain specific chemicals at concentrations that exceed the upper threshold will be designated as hazardous; those below the lower threshold will be nonhazardous; and those with chemical concentrations between the two thresholds will be "special" wastes and subject to variances for management and disposal. The proposed DTSC system combines toxicity information with short or long-term exposure information to determine the risks associated with the chemicals. Under section 57004 of the California Health and Safety Code, the scientific basis of the proposed waste classification system is subject to external scientific peer review by the National Academy of Sciences, the University of California, or other similar institution of higher learning or group of scientists. This report addresses that regulatory requirement.
