The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. This study measures LA's existing tree canopy cover (TCC), determines if space exists for 1 million additional trees, and estimates future benefits from the planting. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. LA's existing TCC was 21%. There is potential to add 2.5 million additional trees to the existing population of 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting were between $1.33 band $1.95 billion.

The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. The purpose of this study was to measure Los Angeles's existing tree canopy cover (TCC), determine if space exists for 1 million additional trees, and estimate future benefits from the planting. Highresolution QuickBird remote sensing data, aerial photographs, and geographic information systems were used to classify land cover types, measure TCC, and identify potential tree planting sites. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. Two scenarios reflected low (17 percent) and high (56 percent) mortality rates. Numerical models were used with geographic data and tree size information for coastal and inland climate zones to calculate annual benefits and their monetary value. Los Angeles's existing TCC was 21 percent, and ranged from 7 to 37 percent by council district. There is potential to add 2.5 million additional trees to the existing population of approximately 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting for the 35-year period were $1.33 billion and $1.95 billion for the high- and low-mortality scenarios, respectively. Average annual benefits were $38 and $56 per tree planted. Eighty-one percent of total benefits were aesthetic/other, 8 percent were stormwater runoff reduction, 6 percent energy savings, 4 percent air quality improvement, and less than 1 percent atmospheric carbon reduction. Recommendations included developing a decisionsupport tool for tree selection and tracking, as well as establishing a model parking lot greening program.

Liberation Science is the practice of using the knowledge and methods of science to solve the social and environmental problems faced by the poor. Liberation Science can address these problems because it has been freed from the flawed scientific paradigms that are linked to the flawed social paradigms of nationalism and capitalism. Three themes of Liberation Science are: 1) The definition of an ecosystem becomes both more expansive and more holistic to include humans, cultural practices, and the built environment, together with the possibility that an ecosystem could mimic the behavior of a single organism. 2) The logic and methods of science are made available to ordinary people, empowering them to understand the ecologies of their own communities. 3) Science becomes open to complementary philosophical approaches that draw upon cultural and spiritual traditions of particular regions or communities.

Developing an up-to-date critical framework for analysing urban retrofit, this is the first book to examine urban re-engineering for sustainability in a socio-technical context. Retrofitting Cities examines why retrofit is emerging as an important strategic issue for urban authorities and untangles the mix of economic, competitive, ecological and social drivers that influence any transition towards a more sustainable urban environment. Retrofitting Cities comparatively explores how urban scale retrofitting can be conceptualised as a socio-technical transition; to critically compare and contrast different national styles of response in cities of the north and global south; and, to develop new research and policy agendas on future development of progressive retrofitting. Bringing together a group of researchers from a variety of disciplinary backgrounds that reflect the complexity of the research challenge, Retrofitting cities looks across different infrastructures and types of built environment, dealing with diverse urban contexts and examining formal as well as community responses. This is a uniquely practical book for urban planning and policy professionals as well as for researchers in urban studies and urban design.

From roots to canopy, a lush, verdant history of the making of California. California now has more trees than at any time since the late Pleistocene. This green landscape, however, is not the work of nature. It’s the work of history. In the years after the Gold Rush, American settlers remade the California landscape, harnessing nature to their vision of the good life. Horticulturists, boosters, and civic reformers began to "improve" the bare, brown countryside, planting millions of trees to create groves, wooded suburbs, and landscaped cities. They imported the blue-green eucalypts whose tangy fragrance was thought to cure malaria. They built the lucrative "Orange Empire" on the sweet juice and thick skin of the Washington navel, an industrial fruit. They lined their streets with graceful palms to announce that they were not in the Midwest anymore. To the north the majestic coastal redwoods inspired awe and invited exploitation. A resource in the state, the durable heartwood of these timeless giants became infrastructure, transformed by the saw teeth of American enterprise. By 1900 timber firms owned the entire redwood forest; by 1950 they had clear-cut almost all of the old-growth trees. In time California’s new landscape proved to be no paradise: the eucalypts in the Berkeley hills exploded in fire; the orange groves near Riverside froze on cold nights; Los Angeles’s palms harbored rats and dropped heavy fronds on the streets below. Disease, infestation, and development all spelled decline for these nonnative evergreens. In the north, however, a new forest of second-growth redwood took root, nurtured by protective laws and sustainable harvesting. Today there are more California redwoods than there were a century ago. Rich in character and story, Trees in Paradise is a dazzling narrative that offers an insightful, new perspective on the history of the Golden State and the American West.

Fully updated and greatly enhanced, the Third Edition of Urban Forestry addresses current issues in planning, establishing, and managing trees, forests, and other elements of nature in urban and community ecosystems. The authors discuss why we have trees in cities and how we use them, clarify the appraisal and inventory of urban vegetation, and extensively delve into the planning and management of public as well as private vegetation. As urban forestry continues to evolve as a profession, foresters and arborists can expect many challenges as well as opportunities. The continuing development of cities has become linked to a much greater emphasis on urban vegetation, the growing demand for recreation amenities within the urban environment, and the careful and successful management of vegetation in an urban ecosystem. New ways to incorporate the highly versatile urban forest resource into the urban fabric will undoubtedly benefit the lives of its residents.

As people increasingly migrate to urban settings and more than half of the world's population now lives in cities, it is vital to plan and provide for sustainable and resilient food systems which reflect this challenge. This volume presents experience and evidence-based "state of the art" chapters on the key dimensions of urban food challenges and types of intra- and peri-urban agriculture. The book provides urban planners, local policy makers and urban development practitioners with an overview of crucial aspects of urban food systems based on an up to date review of research results and practical experiences in both developed and developing countries. By doing so, the international team of authors provides a balanced textbook for students of the growing number of courses on sustainable agriculture, food and urban studies, as well as a solid basis for well-informed policy making, planning and implementation regarding the development of sustainable, resilient and just urban food systems.

At a time when pollution, urban sprawl, and condo booms are leading municipal governments to adopt prescriptive laws and regulations, this book lays the groundwork for a more informed debate between those trying to preserve private property rights and those trying to assert public interests. Rather than asking whether community interests should prevail over the rights of private property owners, Public Interest, Private Property delves into the heart of the argument to ask key questions. Under what conditions should public interests take precedence? And when they do, in what manner should they be limited? Drawing on case studies from across Canada, the contributors examine the tensions surrounding expropriation, smart growth, tree bylaws, green development, and municipal water provision. They also explore frustrations arising from the perceived loss of procedural rights in urban-planning decision making, the absence of a clear definition of “public interest,” and the ambiguity surrounding the controls property owners have within a public-planning system.
