Available in PDF, EPUB and Kindle. Book excerpt: "Around the world, cities provide plenty of opportunities such as better education, advanced health treatment facilities, better employment, commerce, and trade as compared to rural areas. Therefore, more than half the world's people live and work together in urban communities, and it is projected that by the year 2030, three out of five people will stay in cities. The unrestrained and rapid growth of cities has also brought environmental degradation and causes many serious problems such as worsening of air quality, loss of natural habitat and species diversity, and increased human health risks associated with heat waves, noise and crowding. In most urban areas of developing countries, a variety of harmful air pollutants such as particulate matter, carbon monoxide, nitrogen and sulfur oxides, and polycyclic aromatic hydrocarbons are emitted from a variety of sources, mainly the burning of wood, fossil fuels and vehicular emissions, which adversely affects the health of human beings, animals, and other living creatures. In the urban environment, trees provide many economic, social, and environmental benefits to people, such as aesthetic beauty, improvement of property values, erosion prevention, storm water management, noise reduction, mental health development and crime reduction. In addition, trees help cool the air by shading surfaces that otherwise would absorb the sun's energy and then reradiate it out as heat. Trees also cool the ambient air. Urban trees on average reduce air temperatures on summer days by 2-4 °F, although in some circumstances the cooling effect can be even larger. Trees also sequester carbon, helping to mitigate climate change. The efficiency of atmospheric cleansing by trees in congested cities could be improved by planting more trees other than shrubs or herbs. Generally, avenue trees act as living filters to decrease pollution through absorption, accumulation, and detoxification. Trees remove gaseous air pollutants such as ozone, sulphur dioxide, and nitrogen dioxide mainly by uptake via leaf stomata, although some gases are removed by the plant surface. Once inside the leaf, gaseous air pollutants diffuse into intercellular spaces and may be absorbed by water films to form acids or react with inner leaf surfaces. Though some particles can be absorbed into the tree, most particles settle on the branches, leaves and twigs of plants and are washed out by the rain. Throughout the world, different advanced technologies such as smog-free towers in the Netherlands and adhesive roads for particulate matter in London have been applied. However, these technologies are extremely costly and unaffordable for countries like India and therefore the most eco-friendly and cost-effective way is plantation of tolerant tree species alongside highways, city streets, in parks, and in residential yards"--

Book excerpt: An analysis of trees in Washington, D.C. reveals that this city has about 1,928,000 trees with canopies that cover 28.6 percent of the area. The most common tree species are American beech, red maple, and boxelder. The urban forest currently store about 526,000 tons of carbon valued at $9.7 million. In addition, these trees remove about 16,200 tons of carbon per year ($299,000 per year) and about 540 tons of air pollution per year ($2.5 million per year). The structural, or compensatory, value is estimated at $3.6 billion. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the Washington, D.C. area.

Download or read book Urban Forestry written by National Research Council and published by National Academies Press. This book was released on 2013-09-23 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the ecological research in the past decades has focused on rural or wilderness areas. Today, however, ecological research has been taking place in our cities, where our everyday decisions can have profound effects on our environment. This research, or urban ecology, includes an important element, trees. Trees have had a variety of environmental benefits for our environment including the sequestering carbon, reducing urban heat island effects, providing vital habitat for wildlife, and making nature accessible. These benefits have important impacts on the physical, socio-economic, and mental health of humans as well. Being exposed to trees has been shown to enhance social cohesion, improve health and recreational opportunities, and increase real estate values. In order to gain more knowledge into this urban forestry, the National Academy of Sciences (NAS) held a workshop February 25-26, 2013. The workshop brought together more than 100 people with various interests in urban forestry research to share information and perspectives, foster communication across specific areas of ecosystem service research, and consider integrated approaches that cut across these realms. The workshop specifically examined current capabilities to characterize and quantify the benefits, key gaps in our understanding, the challenges of planning urban forests in a way that optimizes multiple ecosystem services and more. Urban Forestry: Toward an Ecosystem Services Research Agenda: A Workshop Summary presents an overview of the issues discussed by the workshop's breakout groups; summarizes presentations from the four panels which included Biophysical Services of the Urban Forest; and context for the study with introductory material from the workshop.
Download or read book The Urban Forest written by David Pearlmutter and published by Springer. This book was released on 2017-02-27 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on urban "green infrastructure" – the interconnected web of vegetated spaces like street trees, parks and peri-urban forests that provide essential ecosystem services in cities. The green infrastructure approach embodies the idea that these services, such as storm-water runoff control, pollutant filtration and amenities for outdoor recreation, are just as vital for a modern city as those provided by any other type of infrastructure. Ensuring that these ecosystem services are indeed delivered in an equitable and sustainable way requires knowledge of the physical attributes of trees and urban green spaces, tools for coping with the complex social and cultural dynamics, and an understanding of how these factors can be integrated in better governance practices. By conveying the findings and recommendations of COST Action FP1204 GreenInUrbs, this volume summarizes the collaborative efforts of researchers and practitioners from across Europe to address these challenges.

Download or read book Growth and Ecosystem Services of Urban Trees written by Thomas Rötzer and published by MDPI. This book was released on 2019-10-23 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous studies indicate an accelerated growth of forest trees, induced by ongoing climate change. Similar trends were recently found for urban trees in major cities worldwide. Studies frequently report about substantial effects of climate change and the urban heat island effect (UHI) on plant growth. The combined effects of increasing temperatures, changing precipitation patterns, and extended growing season lengths, in addition to increasing nitrogen deposition and higher CO2 concentrations, can increase but also reduce plant growth. Closely related to this, the multiple functions and services provided by urban trees may be modified. Urban trees generate numerous ecosystem services, including carbon storage, mitigation of the heat island effect, reduction of rainwater runoff, pollutant filtering, recreation effects, shading, and cooling. The quantity of the ecosystem services is often closely associated with the species, structure, age, and size of the tree as well as with a tree’s vitality. Therefore, greening cities, and particularly planting trees, seems to be an effective option to mitigate climate change and the UHI. The focus of this Special Issue is to underline the importance of trees as part of the urban green areas for major cities in all climate zones. Empirical as well as modeling studies of urban tree growth and their services and disservices in cities worldwide are included. Articles about the dynamics, structures, and functions of urban trees as well as the influence of climate and climate change on urban tree growth, urban species composition, carbon storage, and biodiversity are also discussed.

This book was released on 2015-02-27 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the most important environmental problems faced by Planet Earth. The majority of CO2 emissions come from burning fossil fuels for energy production and improvements in energy efficiency shows the greatest potential for any single strategy to abate global greenhouse gas (GHG) emissions from the energy sector. Energy related emissions account for almost 80% of the EU's total greenhouse gas emissions. The building sector is the largest energy user responsible for about 40% of the EU’s total final energy consumption. In Europe the number of installed air conditioning systems has increased 500% over the last 20 years, but in that same period energy cooling needs have increased more than 20 times. The increase in energy cooling needs relates to the current higher living and working standards. In urban environments with low outdoor air quality (the general case) this means that in summer-time one cannot count on natural ventilation to reduce cooling needs. Do not forget the synergistic effect between heat waves and air pollution which means that outdoor air quality is worse in the summer aggravating cooling needs. Over the next few years this phenomenon will become much worse because more people will live in cities, more than 2 billion by 2050 and global warming will aggravate cooling needs.

Download or read book Pathways to Urban Sustainability written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-11-11 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities have experienced an unprecedented rate of growth in the last decade. More than half the world's population lives in urban areas, with the U.S. percentage at 80 percent. Cities have captured more than 80 percent of the globe's economic activity and offered social mobility and economic prosperity to millions by clustering creative, innovative, and educated individuals and organizations. Clustering populations, however, can compound both positive and negative conditions, with many modern urban areas experiencing growing inequality, debility, and environmental degradation. The spread and continued growth of urban areas presents a number of concerns for a sustainable future, particularly if cities cannot adequately address the rise of poverty, hunger, resource consumption, and biodiversity loss in their borders. Intended as a comparative illustration of the types of urban sustainability pathways and subsequent lessons learned existing in urban areas, this study examines specific examples that cut across geographies and scales and that feature a range of urban sustainability challenges and opportunities for collaborative learning across metropolitan regions. It focuses on nine cities across the United States and Canada (Los Angeles, CA, New York City, NY, Philadelphia, PA, Pittsburgh, PA, Grand Rapids, MI, Flint, MI, Cedar Rapids, IA, Chattanooga, TN, and Vancouver, Canada), chosen to represent a variety of metropolitan regions, with consideration given to city size, proximity to coastal and other waterways, susceptibility to hazards, primary industry, and several other factors.

Download or read book Urban Ecosystem Services written by Alessio Russo and published by MDPI. This book was released on 2021-05-07 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The school of thought surrounding the urban ecosystem has increasingly become in vogue among researchers worldwide. Since half of the world’s population lives in cities, urban ecosystem services have become essential to human health and wellbeing. Rapid urban growth has forced sustainable urban developers to rethink important steps by updating and, to some degree, recreating the human–ecosystem service linkage. Assessing, as well as estimating the losses of ecosystem services can denote the essential effects of urbanization and increasingly indicate where cities fall short. This book contains 13 thoroughly refereed contributions published within the Special Issue “Urban Ecosystem Services”. The book addresses topics such as nature-based solutions, green space planning, green infrastructure, rain gardens, climate change, and more. The contributions highlight new findings for landscape architects, urban planners, and policymakers. Important future cities research is considered by looking at the system connectivity between the social and ecological sphere—via varying forms of urban planning, management, and governance. The book is supported by methods and models that utilize an urban sustainability and ecosystem service-centric focus by adding knowledge-base and real-world solutions into the urbanization phenomenon.
