Drosscape is an urban design framework that looks at urbanized regions as the waste product of defunct economic and industrial processes. The concept was realized by Alan Berger, professor of urban design at MIT, and is part of a new vocabulary and aesthetic that could be useful for the redesign and adaptive reuse of ‘waste landscapes’ within urbanized regions. [1]
According to Berger, drosscape, as a concept, implies that dross, or waste, may be "scaped", or resurfaced, and reprogrammed for adaptive reuse. Berger goes on to explain that this phenomenon emerges from two primary processes. Firstly, Drosscape surfaces as a byproduct of rapid urbanization and horizontal growth urban sprawl. Secondly, these spaces arise as a consequence of defunct economic and production systems. [2] For urban planners, architects and other design professionals, drosscape may offer another creative way to envision space and landscape design in a city. According to Berger, “Adaptively reusing this waste landscape figures to be one of the twenty-first century’s great infrastructural design challenges.”
These waste places have risen from deindustrialization as well as industrial growth, the latter having replaced old technologies with new ones... leading to “creative destruction”, or the abolishment of the obsolete. This concept also forgives sprawl, explaining that industrial growth and success in urban centers causes this inevitable, horizontal movement, and isn’t intrinsically bad. Again, this will require a new line of thinking, as we’ve been trained to fear sprawl and to despise the landscape that humans have created. Once the waste landscapes are identified, it will be the job of the entrepreneurial design professional to integrate and re-use these spaces in the urban world.
Berger cites the following examples as demonstrating the horizontal urbanization which results in "wasted landscapes".
Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid sprawl. It also advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. The term "smart growth" is particularly used in North America. In Europe and particularly the UK, the terms "compact city", "urban densification" or "urban intensification" have often been used to describe similar concepts, which have influenced government planning policies in the UK, the Netherlands and several other European countries.
Urban design is an approach to the design of buildings and the spaces between them that focuses on specific design processes and outcomes. In addition to designing and shaping the physical features of towns, cities, and regional spaces, urban design considers 'bigger picture' issues of economic, social and environmental value and social design. The scope of a project can range from a local street or public space to an entire city and surrounding areas. Urban designers connect the fields of architecture, landscape architecture and urban planning to better organize physical space and community environments.
Urbanization is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas.
Urban studies is the diverse range of disciplines and approaches to the study of all aspects of cities, their suburbs, and other urban areas. This includes among others: urban economics, urban planning, urban ecology, urban transportation systems, urban politics, sociology and urban social relations. This can be contrasted with the study of rural areas and rural lifestyles.
Urban ecology is the scientific study of the relation of living organisms with each other and their surroundings in an urban environment. An urban environment refers to environments dominated by high-density residential and commercial buildings, paved surfaces, and other urban-related factors that create a unique landscape. The goal of urban ecology is to achieve a balance between human culture and the natural environment.
Urban geography is the subdiscipline of geography that derives from a study of cities and urban processes. Urban geographers and urbanists examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non-human bodies, patterns of development and infrastructure, political and institutional activities, governance, decay and renewal, and notions of socio-spatial inclusions, exclusions, and everyday life. Urban geography includes different other fields in geography such as the physical, social, and economic aspects of urban geography. The physical geography of urban environments is essential to understand why a town is placed in a specific area, and how the conditions in the environment play an important role with regards to whether or not the city successfully develops. Social geography examines societal and cultural values, diversity, and other conditions that relate to people in the cities. Economic geography is important to examine the economic and job flow within the urban population. These various aspects involved in studying urban geography are necessary to better understand the layout and planning involved in the development of urban environments worldwide.
Urban sprawl is defined as "the spreading of urban developments on undeveloped land near a city." Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The cost of building urban infrastructure for new developments is hardly ever recouped through property taxes, amounting to a subsidy for the developers and new residents at the expense of existing property taxpayers.
Suburbanization, or suburbanisation, is a population shift from central urban areas into suburbs, resulting in the formation of (sub)urban sprawl. As a consequence of the movement of households and businesses out of the city centers, low-density, peripheral urban areas grow. Sub-urbanization is inversely related to urbanization (urbanisation), which denotes a population shift from rural areas into urban centers.
Adaptive reuse refers to the process of reusing an existing building for a purpose other than which it was originally built or designed for. It is also known as recycling and conversion. Adaptive reuse is an effective strategy for optimizing the operational and commercial performance of built assets. Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. It has prevented thousands of buildings' demolition and has allowed them to become critical components of urban regeneration. Not every old building can qualify for adaptive reuse. Architects, developers, builders and entrepreneurs who wish to become involved in rejuvenating and reconstructing a building must first make sure that the finished product will serve the need of the market, that it will be completely useful for its new purpose, and that it will be competitively priced.
Michael Robert Van Valkenburgh is an American landscape architect and educator. He has worked on a wide variety of projects in the United States, Canada, Korea, and France, including public parks, college campuses, sculpture gardens, city courtyards, corporate landscapes, private gardens, and urban master plans.
The sustainable city, eco-city, or green city is a city designed with consideration for [[Sustainability|social, to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.
Landscape urbanism is a theory of urban design arguing that the city is constructed of interconnected and ecologically rich horizontal field conditions, rather than the arrangement of objects and buildings. Landscape Urbanism, like Infrastructural Urbanism and Ecological Urbanism, emphasizes performance over pure aesthetics and utilizes systems-based thinking and design strategies. The phrase 'landscape urbanism' first appeared in the mid 1990s. Since this time, the phrase 'landscape urbanism' has taken on many different uses, but is most often cited as a postmodernist or post-postmodernist response to the "failings" of New Urbanism and the shift away from the comprehensive visions, and demands, for modern architecture and urban planning.
Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle.
Urban metabolism is a model to facilitate the description and analysis of the flows of the materials and energy within cities, such as undertaken in a material flow analysis of a city. It provides researchers with a metaphorical framework to study the interactions of natural and human systems in specific regions. From the beginning, researchers have tweaked and altered the parameters of the urban metabolism model. C. Kennedy and fellow researchers have produced a clear definition in the 2007 paper The Changing Metabolism of Cities claiming that urban metabolism is "the sum total of the technical and socio-economic process that occur in cities, resulting in growth, production of energy and elimination of waste." With the growing concern of climate change and atmospheric degradation, the use of the urban metabolism model has become a key element in determining and maintaining levels of sustainability and health in cities around the world. Urban metabolism provides a unified or holistic viewpoint to encompass all of the activities of a city in a single model.
Land recycling is the reuse of abandoned, vacant, or underused properties for redevelopment or repurposing.
Green urbanism has been defined as the practice of creating communities beneficial to humans and the environment. According to Timothy Beatley, it is an attempt to shape more sustainable places, communities and lifestyles, and consume less of the world's resources. Urban areas are able to lay the groundwork of how environmentally integrated and sustainable city planning can both provide and improve environmental benefits on the local, national, and international levels. Green urbanism is interdisciplinary, combining the collaboration of landscape architects, engineers, urban planners, ecologists, transport planners, physicists, psychologists, sociologists, economists and other specialists in addition to architects and urban designers.
Technical aspects of urban planning involve the technical processes, considerations and features that are involved in planning for land use, urban design, natural resources, transportation, and infrastructure.
Landscape architecture competitions are structured similarly to other types of design competitions. In the case of landscape architecture design competitions, the procedure is sponsored by an organization or client that intends on implementing a new landscape design to a property in their care or ownership. Just as in architectural design competitions, the winning design is usually selected by an independent jury composed of design professionals and stakeholders such as government and/or local representatives. In general, design competitions are often used to stimulate new ideas in design, generate public debate, serve as a form of public relations for the project in question and integrate emerging designers into a more level field of competition.
Sheila Kennedy is an American architect and professor at the Massachusetts Institute of Technology (MIT) who is known for including green technology, such as flexible solar cells, into her designs. She is interested in using technology in new ways and in re-examining traditional ways of building and designing structures.
A sponge city is a new urban construction model for flood management, strengthening ecological infrastructure and drainage systems, proposed by Chinese researchers in early 2000 and accepted by the Chinese Communist Party (CCP) and the State Council as urbanism policy in 2014. It can alleviate urban flooding, water resources shortage, and the urban heat island effect and improve the ecological environment and biodiversity by absorbing and capturing rain water and utilizing it to reduce floods. Rain water harvested can be repurposed for irrigation and for home use. It is a form of a sustainable drainage system on an urban scale and beyond. Sponge city policies are a set of nature based solutions that use natural landscapes to catch, store and clean water; the concept has been inspired by ancient wisdom of adaptation to climate challenges, particularly in the monsoon world.
