The most affected in this regard will be the large settlements, characterized by high densities of popu- lation and constructions; consequently, the planners will have to rethink their structure and functions in order to meet the needs for a sustainable urban living. But what do we actually mean by sustainable urban living in the cities of the 21st century?
In the 21st century, sustainable urban living depends on a proper urban planning, which gives the modern urbanism a new conceptual dimension. Urban planning hinweise und w�nsche zum forum a concept that encompasses the entire set of prospective activities aiming at regulating the development of urban territorial systems the regulation of land use, infrastructure planning etc.
Carter defined urban and regional planning as the capa- city to manipulate shape and place. Urban planning can include urban reneval, by adapting urban planning methods to the existing cities suffering from decline. In the late 20th cen- tury, the term sustainable development has represented an ideal outcome in the sum of all planning goals Wheeler, p. Urbanism interferes widely both with the natural environment and with the artificial or human-made one, through complex theoretical and operational relationships, sometimes difficult to define and quantify Alpopi, ; Ellin, ; Waldheim, Urbanism is often identified with urban planning, although by definition the term is more comprehensive.
It includes elements of spatial arrangement, dynamics, func- tionality, as well as flows of matter and energy, which are considered input-output elements for the complex territorial system called urban environment.
The personality of the green city was revealed through qualitative and quantitative analysis methods, based on modern and effective investigation tools remote sensing and GIS techniques. The analysis of green and blue-green components is the key contributi- on of this chapter, as these represent the fundamental structure of the green city.
Remote sensing allows the identification and analysis of green areas on satellite imagery NDVI calculation and distribution reveals the qualitative features of the green areas. GIS tools and techniques are useful for the spatial analysis of green areas, for overlapping layers of information and for highlighting the elements of interest. These tools were used to analyze the urban and suburban forest areas of selected European metropolises: Frankfurt am Main, Vienna and Katowice.
Forest green was emphasized on reclassified raster images maximum likelihood after processing the band combination.
The efficient creation and management of high quality green components within the urban territorial space requires the implementation of appropriate measures, which are in- tegrated in the present study: re-establishing the values of urban ecosystem; resources and energy saving; sustainable management of urban waste etc. This study represents a synthesis of this project and focuses on selected green cities in Europe.
These concepts are based on the principle that the city acts as a living organism with complex metabolism Kennedy et al. The specialty literature promotes new urban concepts meant for this purpose, such as new urbanism, green urbanism, biourbanism or organic urbanism, biophilic city, smart city, sustainable city, eco-city and green city.
According to Beatleynew urbanism should be identified, especially when it comes to urban plan- ning and sustainable thinking, with green urbanism. This is a form of creating beneficial urban communities, both for the people and for the environment, by minimizing matter and energy consumption. By its content, originality, implementation degree and variety of app- roached components, green urbanism identifies itself with the European countries Beatley, Indeed, green urbanism emerged and developed in Europe, but the Americans noticed the benefits it offered and did not fail to take the mo- del.
Besides, they had the advantage of space. Biophilia is a term popularized by E. Wilson to describe the relationship of man with nature and other life forms. The biophilic cities contain large amounts of natural ele- ments and are oriented towards the protection, preservation and restoration of nature Wil- son, They integrate nature in the urban design Beatley, InR.
The sustainable cities or eco-cities are designed by taking into account their impact on the environment, in the sense of minimi- zing waste production and pollution, as well as the inputs of energy, water and food. These targets also constitute the principles of sustainable urban development Habitat, A similar concept is the smart city. A city may be defined as smart when the invest- ments in socio-human capital, urban infrastructure, and rational management of natural resources encourage a sustainable economic development and a high quality of life through participatory actions and commitment from community members Caragliu et al.
The green city means a way to increase the sustainability of urbanized areas.Walk through most contemporary cities, and the mazes of concrete and steel can be some of the most intimidating and confusing places to visit. Buildings rise up dozens of stories from the street and spread for miles out of view. Despite how hectic cities and their surrounding areas can be, attempts at creating models of the way cities function have been made and analyzed to make our understanding of the urban environment richer.
One of the first models created for use by academics was the concentric zone model, developed in the s by urban sociologist Ernest Burgess. What Burgess wanted to model was Chicago's spatial structure with regards to the usage of "zones" around the city.
These zones radiated from Chicago's center, The Loop, and moved concentrically outward. In the example of Chicago, Burgess designated five different zones that had separate functions spatially.
The first zone was The Loop, the second zone was the belt of factories that were directly outside of The Loop, the third zone included homes of laborers who worked in the factories, the fourth zone contained middle-class residences, and the fifth and final zone hugged the first four zones and contained the homes of the suburban upper class.
Keep in mind that Burgess developed the zone during an industrial movement in America and these zones worked mainly for American cities at the time.
Attempts at applying the model to European cities have failed, as many cities in Europe have their upper classes located centrally, whereas American cities have their upper classes mostly at the periphery. The five names for each zone in the concentric zone model are as follows:.
Since the concentric zone model isn't applicable to many cities, some other academics attempted to further model the urban environment. One of these academics was Homer Hoyt, a land economist who was mostly interested in taking a look at rents within a city as a means of modeling the city's layout.
The Hoyt model also known as the sector modelwhich was developed intook into account the effect of transportation and communication on a city's growth. His thoughts were that rents could remain relatively consistent in certain "slices" of the model, from the downtown center all the way to the suburban fringe, giving the model a pie-like look.
This model has been found to work especially well in British cities. A third well-known model is the multiple-nuclei model. This model was developed in by geographers Chauncy Harris and Edward Ullman to try and further describe a city's layout. Harris and Ullman made the argument that the city's downtown core CBD was losing its importance in relation to the rest of the city and should be seen less as the focal point of a city and instead as a nucleus within the metropolitan area.
The automobile began to become increasingly important during this time, which made for greater movement of residents to the suburbs. Since this was taken into consideration, the multiple-nuclei model is a good fit for sprawling and expansive cities.
These nuclei develop into independent areas because of their activities. For example, some economic activities that support one another for instance, universities and bookstores will create a nucleus.Summary: Urban Planning is a large-scale concept concerned with planning and development at all levels architectural, infrastructural, ecological, economic, and even political.
On the other hand, English Lexicon describes Urban Planning as a branch of architecture dealing with the design and organization of urban space and activities besides determining and drawing up plans for the future physical arrangement.
Here in IEREKwe believe that Urban Planning must be accompanied by sustainability concept which enables us to carry out the urban development process in the right way to keep up the sustainable environment for future generations. The basic concern of city-town planning is the internal form, structure, function, and appearance of urban areas.
Physical aspects such as buildings, roads, land use, etc. Urban Sprawl refers to the migration of a population from populated towns and cities to low-density residential development over more and more rural land which results in:.
Private ownership of small parcels of urban land sometimes interferes with the effective control of the space pattern of the city like the following:. Affordable housing is housing deemed affordable to those with a median household income. Housing choice is a response to an extremely complex set of economic, social, and psychological impulses as follows:. As we mentioned before Urban Planning must be accompanied by the sustainability concept.
Here where we should stand and understand that the city is more than the sum of its parts. It is a whole living thing that is constantly changing, evolving and morphing into an ever more ECO-Friendly and welcoming entity which can be achieved through innovative sustainable solutions such as following:. Census population doubles which require more housing spaces, yet our goal to meet the needs of the present without compromising the ability of future generations to meet their own needs.
Affordable Housing has become a commonly used term for summarizing the nature of the housing difficulty in many nations. He identifies six elements of measuring housing expenditure to an income ratio to measure housing affordability.
There is a need for Zero-Carbon Cities which are urban areas powered by renewable energy techniques and technologies. A zero-carbon city runs entirely on renewable energy; it has no carbon footprint and will in this respect not cause harm to the planet.
Most cities throughout the world produce energy by burning coal, oil, and gas, unintentionally emitting carbon. Almost every activity human does involve burning one of these fossil fuels.
To become a zero carbon city, an established modern city must collectively reduce emissions of greenhouse gases to zero and all practices that emit greenhouse gases must cease. It can be achieved by the following steps:. Green Roofs roofs with a vegetated surface and substrate provide ecosystem services in urban areas, including improved storm-water management, better regulation of building temperatures, reduced urban heat-island effects, and increased urban wildlife habitat.
Just imagine if this technology was applied to every building within your city, it comes with unlimited benefits as following:. Transport has a major impact on the spatial and economic development of cities and regions. The attractiveness of particular locations depends in part on the relative accessibility, and this in turn depends on the quality and quantity of the transport infrastructure. In further articulating this idea, the Center for Sustainable Transportation has defined a sustainable transportation system as one that:.
Depending on modern-technology we can convert current polluting transportation into an environmentally friendly one. UPADSD aims to bring together, scientists, urban planners, architects and other stakeholders from across the globe to discuss the latest scientific advances in the field.

What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller?
To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion -- imageability -- and shows its potential value as a guide for the building and rebuilding of cities. This definitive sourcebook on urban planning points out what has and hasn't worked in the ongoing attempt to solve the continuing problems of American cities.
Hundreds of examples and case studies clearly illustrate successes and failures in urban planning and regeneration, including examples of the often misunderstood and maligned "Comprehensive Plan. Lynch looks at connections between human values and the physical forms of cities, sets requirements for a normative theory of city form, reviews earlier physical images of what utopian communities might be, sees what is to be learned from hellish images, and helps us place city forms into one or another of three theoretic constructs; cosmic or ceremonial centers, the machine city, and the city as an organism.
One of the strongest supporters of New Urbanism, architect and urban designer Peter Calthrope makes the case for compact, mixed-use development over the urban sprawl that has dominated much of the development in the past decades. Twenty-four regional plans are presented in the book, focusing on reducing dependance on the automobile and increasing the proximity between home, work, shopping and recreation.

Rational Planning Model
This edition is a collection of much of the original work. The first book to describe an ecologically sound approach to the planning and design of communities, Design with Nature has done much over the past 25 years to shape public environmental policy.
This paperback edition makes this classic accessible to a wider audience than ever before. Lavishly illustrated with more than color photos and line drawings.Starting in the 20th century, a number of urban planning theories came into prominence and, depending on their popularity and longevity, influenced the appearance and experience of the urban landscape. The primary goal of city planning in the midth century was comprehensiveness.
An increasing recognition of the interdependence of various aspects of the city led to the realization that land use, transport, and housing needed to be designed in relation to each other.
The rational model was briefly hegemonic, but this scientific approach to public-policy making was quickly challenged by critics who argued that the human consequences of planning decisions could not be neatly quantified and added up. The modernist model, involving wholesale demolition and reconstruction under the direction of planning officials isolated from public opinioncame under fierce attack both intellectually and on the ground.
Most important in undermining support for the modernist approach was urbanologist Jane Jacobs. Jacobs criticized large-scale clearance operations for destroying the complex social fabric of cities and imposing an inhuman orderliness. Rather than seeing high population density as an evil, she regarded it as an important factor in urban vitality.
She considered that a lively street life made cities attractive, and she promoted diversity of uses and population groups as a principal value in governing urban development. According to Jacobs, urban diversity contributes to sustainable growth, whereas undifferentiated urban settings tend to depend upon unsustainable exploitation, exhibited in the extreme form by lumber or mining towns that collapse after the valuable resources have been removed. Jacobs was not alone in her criticism.
Beginning in the s, urban social movements, at times amounting to insurrection, opposed the displacements caused by large-scale modernist planning. In cities throughout the United States and Europe, efforts at demolishing occupied housing provoked fierce opposition.
Within developing countries, governmental attempts to destroy squatter settlements stimulated similar counteroffensives. Within developing countries, however, the modernist concepts of the earlier period still retained a significant hold.
Thus, for example, China, in preparation for the Beijing Olympics ofengaged in major displacement of its urban population to construct roads and sports facilities, and it likewise developed new commercial districts by building high-rise structures along the functionalist Corbusian model.
The ways in which planning operated at the beginning of the 21st century did not conform to a single model of either a replicable process or a desirable outcome. Within Europe and the United States, calls for a participatory mode—one that involved residents most likely to be affected by change in the planning process for their locales—came to be honoured in some cities but not in others. The concept of participatory planning has spread to the rest of the world, although it remains limited in its adoption.
Generally, the extent to which planning involves public participation reflects the degree of democracy enjoyed in each location. Where government is authoritarianso is planning. In sum, the enormous variety of types of projects on which planners work, the lack of consensus over processes and goals, and the varying approaches taken in different cities and countries have produced great variation within contemporary urban planning.
Nevertheless, although the original principle of strict segregation of uses continues to prevail in many places, there is an observable trend toward mixed-use development—particularly of complementary activities such as retail, entertainment, and housing—within urban centres.

Among these Rational Planning Model is considered to be most successful and even used today. This multi-step model and aims to be logical and follow the orderly path from problem identification through solution. The RCM Rational Comprehensive Model for planning owes its origins to Enlightenment epistemology Sandercock, ; Allmendinger,as it is centred on decisions and principles that are based on reason, logic and scientific facts with little or no emphasis on values and emotions.Superblocks: How Barcelona is taking city streets back from cars
Therefore, the planner learns from experience and can define the correct method or procedure to follow to get the correct result. Related: Advocacy Planning Concept. It focuses on the means rather than the ends, favours facts over values, and is often used in bureaucracies. A major problem with formal rationality is that it cannot show us what goals we ought to prefer. In using the example of robbing a bank, Faludi proposes that there is a rational way to robbing a bank but the goal itself is wrong.

Rationality is thus contextual. Substantive rationality is more concerned with ends and their evaluation rather than the means themselves Allmendinger, It is less scientific than formal rationality and it considers more than simply efficiency and effectiveness.
Related: Collaborative Planning Theory. They maintain that no common social interest exists and that the RCM neglects the interests of both the poor and nature Campbell and Fainstein The comprehensiveness of the model has also come under question by such critics as Lindblom in Campbell and Fainstein and Altshulerwho argue that due to limited time and resources available for making a decision and exploring all alternative options it is practically impossible to be thoroughly comprehensive Taylor ; Campbell and Fainstein It also requires an exceptional level of knowledge, analysis and organisational coordination to absorb and make sense of all the relevant information; planners may end up being more confused and thus less rational Campbell and Fainstein ; Taylor Knowledge gained from these practical and analytical modes by definition exclude those without professional training.
This knowledge is based on technical jargons and is preferred to knowledge gained through other practices such as talking, listening, seeing, contemplating, and sharing. Adding to the above limitations, there are a lot of assumptions, requirements without which the rational decision model is a failure. Therefore, they all have to be considered.
The model assumes that we have or should or can obtain adequate information, both in terms of quality, quantity and accuracy.
