This book will address the destruction of urban forest in nine cities by bombing during World War II and the Bosnian War and their reconstruction in the post-war years. After reviewing the general objectives and results of aerial bombing, the book explores the effects of bombing and the reconstruction of urban forest in London, Coventry, Hamburg, Dresden, St. Petersburg, Stalingrad, Tokyo, Hiroshima, and Sarajevo. Sarajevo stands out among these cities because the destruction of its urban forest was the result of citizens cutting down trees for firewood during the siege of the city. Most of the cities studied developed plans for reconstruction either during or after the war. These plans often addressed the planning and re-establishment of the urban forest that had been destroyed. Urban planners often planned for infrastructure improvements such as new boulevards and parks where trees would be planted. After the war many of these plans were abandoned or significantly modified. Cost, resistance by property owners, control of reconstruction by authorities outside of the cities, and the lack of planting stock were factors contributing to the failure of many of the plans. Exceptions occurred in Hiroshima and Coventry where the destroyed cities became symbols of national reconstruction and every effort was made to redesign the destroyed portions of these cities as memorials to those who lost their lives and to demonstrate the rebirth of the cities. In several of the cities studied individual citizens undertook on their own the replanting of street and park trees. Their ingenuity, hard work, and dedication to trees in their cities was remarkable. A common factor limiting efforts to replant street and park trees was the lack of nursery stock. During and immediately after the wars nearly all nurseries that had supplied trees for city planting had been converted to vegetable gardens to produce food for the urban populations. The slow return to the production of trees for urban planting was a common factor in the time required in many cities to restore their street and park trees. There are lessons to be learned by urban planner, urban forester, and landscape architects from this book that will be useful in the future destruction of urban forest either by natural or man-made causes.
Millions of urbanites never see primeval forests during their lives except for the old growth forests found in urban parks. Unfortunately, these forests are on the verge of disappearing because arboreal reproduction is lost to human trampling and park administrators and urban foresters do not maintain these “natural” forests. To aid urban foresters and park managers in meeting the challenges, research on old growth forests in urban parks is synthesized in terms of historical ecology to introduce the methods utilized to reveal long-term forest composition changes. The case study of three stands in Fairmount Park, Philadelphia, PA relates pre-chestnut blight tree species densities and post-chestnut blight arboreal changes to fire and visitor trampling. The information gained on how urban old growth forests have developed and changed is used to develop restoration ecology based frameworks to restore species composition and address challenges to forest survival including invasive species.
Cities need forests. The network of woodlands, groups of trees and individual trees in a city and on its fringes performs a huge range of functions – such as regulating climate; storing carbon; removing air pollutants; reducing the risk of flooding; assisting in food, energy and water security; and improving the physical and mental health of citizens. Forests enhance the look of cities and play important roles in social cohesion; they may even reduce crime. This edition of Unasylva takes a close look at urban and peri-urban forestry – its benefits, pitfalls, governance and challenges.
Trees and vegetation in cities aren’t just there to make the place look pretty. They have an important ecological function. This book contains studies and perspectives on urban forests from a broad array of basic and applied scientific disciplines including ecosystem ecology, biogeochemistry, landscape ecology, plant community ecology, geography, and social science. The book includes contributions from experts around the world, allowing the reader to evaluate methods and management that are appropriate for particular geographic, environmental, and socio-political contexts.
Creation and access to green spaces promotes individual human health, especially in therapeutic contexts among those suffering traumatic events. But what of the role of access to green space and the act of creating and caring for such places in promoting social health and well-being? Greening in the Red Zone asserts that creation and access to green spaces confers resilience and recovery in systems disrupted by violent conflict or disaster. This edited volume provides evidence for this assertion through cases and examples. The contributors to this volume use a variety of research and policy frameworks to explore how creation and access to green spaces in extreme situations might contribute to resistance, recovery, and resilience of social-ecological systems.
"Up By Roots is a manual for landscape architects, architects, urban foresters, and planners who are designing, specifying, installing and managing trees in the built environment. Part One discusses basic soil science and tree biology and their relationship to healthy trees. Part Two explains the process of planning and implementing landscape designs to ensure healthy trees that can improve the quality of places where people live, work and play. The book contains numberous illustrations and data in graphic form to provide guidance in the design of healthy soils and trees."--Pub. desc.
Cities are amongst our greatest creations. Yet, with cities now home to over half the world's population, there is increasing concern over their unchecked expansion and the detrimental effect this is having on the planet. This unfettered growth is affecting every ecosystem on Earth, from the deepest oceans to the highest mountains, as induced climate change and ever increasing demands upon the world's resources take effect. As the pace of urbanisation quickens, how can we make the world's cities more sustainable? Ian Douglas tells the story of cities. He shows why they exist, how they have evolved and the problems they have encountered, revealing how from the very beginning environmental management played a key role in urban life. He addresses specific problems, such as noise and air pollution, water supply and waste management, as well as the vulnerability of cities to hazards such as earthquakes and flooding. And he considers strategies to make cities more sustainable and help them adapt to climate change, such as waste recycling, energy conservation, dual water systems, sustainable housing, as well as initiatives to retrofit existing cities. Written by an acknowledged international authority, this unique volume will be welcomed by students and specialists in environment, planning, geography, ecology and the built environment.
In this interdisciplinary textbook, which bridges the gap between the natural and social sciences both, the scientific principles of restoration ecology and practical aspects of ecosystem restoration are comprehensively presented. The diversity of land-use types with a focus on Central Europe is highlighted and case studies of practical restoration projects are presented. The textbook offers students who deal with the environment as well as scientists and practitioners a profound and up-to-date, but also critical overview of the state of knowledge. This book opens up the broad spectrum of degraded ecosystems of Central European natural and cultural landscapes. In further chapters, marine ecosystems and their restoration as well as development potentials and the limits of restoration are discussed in more detail. The ecological fundamentals are expanded through an interdisciplinary perspective taking into account environmental ethics, sociology, anthropology, and economics. In addition to an up-to-date overview of the various areas and fields of activity in restoration ecology and ecosystem restoration, the textbook provides a valuable basis for studies, science, and practice. The students also receive assistance in searching for literature and critical fact analysis, and the lecturers on teaching formats and interdisciplinary approaches to discussion in restoration ecology.
