4. Settlement formed of isolated or dispersed homestead Settlements can further be classified according to size and spacing into: clustered or compact and dispersed or scattered.
SETTLEMENT HIERARCHY
i. Isolated dwellings
Such settlement consists of individual units. It can be termed as the initial stage of development of a settlement.
An isolated dwelling would only have 1 or 2 buildings or families in it. ii. Hamlets
When many individual units are cluster together they form hamlets. The grouping may be due to similar occupational patterns, religion, cultural factors etc. A hamlet has a tiny population (<100) and very few (if any) services
iii. Villages
When many hamlets combine they form a village. The reason for such grouping may be due to interdependencies of one hamlet on another, thus to form a self-sufficient unit.
iv. Towns
A town is a larger entity which is more self-sufficient, has a stronger economic base. v. Cities
Where large concentration of people exists, multiple economic activities exist. vi. Metropolis
A metropolis is a large city, with a population of at least one million living in its urban agglomeration.
vii. Megalopolis
An extensive, metropolitan area or a long chain of continuous metropolitan areas. viii Ecumenopolis
The entire area of earth that is taken up by human settlements
TYPES OF SETTLEMENTS
There is a great variation in the settlement types due to geographical, cultural and economical factors, settlements can be broadly classified into
• Temporary settlements • Permanent settlements • Urban settlements • Rural settlements
There are many reasons why humans make the choices they do about building settlements. Factors include:
Physical Features
• Body of water (transportation routes, water for drinking and farming) • Flat land (easy to build) • Fertile soil (for crops)
• Forests (timber and housing)
Human Factors
• people who share a common language, religion or culture,social network or supports
• quality of life • employment
Factors can be push or pull. Push factors encourage a family to emigrate (pushes them to leave a location). Pull factors encourage a family to immigrate (pulls them in to move to a location). Push factors:
➢ Population pressure
➢ Poor infrastructure
➢ Inadequate jobs
➢ Bad educational options
➢ Poor health care
➢ Ecological problems
➢ Natural disasters
Pull factors:
Improved standard of living
Better health care and availability of services Varied employment opportunities
Higher wages
Quality of education No social compulsions
ELEMENTS OF HUMAN SETTLEMENTS
1. The Content: Man, Society and Networks
2. The Container: Physical Settlement (Nature and Shell)
➢ Nature-Earth and the natural site on which settlements are built.
➢ Man (Anthropos) - creates and inhabits the settlements
➢ Society - Formed in given settlement
➢ Networks - Functions that allow settlements to survive and grow
➢ Shells - Built to transform the first and to house the other elements
FOUR BASIC PARTS OF COMPOSITE HUMAN SETTLEMENTS
➢ The Homogeneous parts - the fields
➢ The Central parts - the built up village
➢ The Circulatory parts - roads and paths w ithin the fields
EVOLUTION OF HUMAN SETTLEMENTS
Phase 1: Primitive non-organized human settlements (started with evolution of human beings) Phase 2: Primitive organized settlements – Eopolis (The period of villages lasted 10,000 years) Phase 3: Static Urban settlements or cities – Polis (Lasted about 5,000-6,000 years)
Phase 4: Dynamic Urban settlements – Dynapolis (Lasted 200-400 years) Phase 5: Universal City – Ecumenopolis (which is now beginning)
Phase 1: Primitive non-organized human settlements:
➢ Man began to modify nature
➢ Man settled temporarily or permanently in different locations
➢ Began with fire and went on to animal husbandry and domestication of grazing animals
➢ Deforestation and agriculture complemented with permanent human settlements
➢ Settlements: Natural shelters – hollows in the ground, hollow trees or shallow caves
➢ Settlements have no link, communication lines and transportation Phase 2: Primitive organized settlements – Eopolis:
➢ Entry to the era of organized agriculture coupled with organized settlements
➢ Due to loss of space between them, more regular shapes of settlements were formed to a regular grid iron pattern
➢ Micro scale: Man must divide the land, construct one or more shells (rooms and houses) and circulate within a built up area (neighbourhood)
➢ Macro scale: Man must own and use space but not build it, and circulate within it, although to a much lesser degree than before, man continues to follow the course of nature towards
hexagonal patterns
➢ Population is still small
➢ Villages are found in plains, near the rivers and the seas
➢ When population density increased, new patterns were developed with t he villages covering the entire plain based on small hexagonal pattern and the hills and mountains on a larger hexagonal pattern.
Phase 3: Static Urban settlements or cities – Polis:
➢ First Urban settlements appeared as small cities in a plain or as fortresses on hills and mountains (5000 – 6000 years ago)
➢ Expansion of nucleus in one or more directions Phase 4: Dynamic Urban settlements – Dynapolis:
➢ Started in the 17th century
➢ Characterized by continuous growth
➢ Emerged due to Industrial technological revolution
➢ All part of the land it covers is not sterilized
➢ Micro organisms in the soil no longer exist
➢ Original animal inhabitants have largely been banished Phase 5: Universal City – Ecumenopolis:
➢ Possible occurrence of population explosion
➢ Earth will be covered by one settlement
➢ Cities will be interconnected, into one continuous network into o ne Universal city called Ecumenic city
Ecumenopolis on the Earth in the year 2120, by which time it is expected that the population of the earth will have levelled off at a minimum of 20,000,000,000 people and the population of the definitely Urban areas at a minimum of 18,000,000,000 people.

FORMS OF HUMAN SETTLEMENTS
Structure and form of Human settlements – Linear, non-linear and circular – Combinations – reasons for development – advantages and disadvantages – case studies – factors influencing the growth and decay of human settlements.
FORMS OF HUMAN SETTLEMENTS
A settlement may be as small as a single house in a remote area or as large as a mega city.
A settlement may also be permanent or temporary (refugee camp). and a tem porary settlement may become permanent over time.
The piece of land upon a settlement is built is the settlement site.
There are many reasons why a site might be chosen for the develo pment of a settlement and some factors will be more important than others. Also, the importance of this factors may vary over time.
SETTLEMENT SITE AND SITUATION:
The situation of a settlement is its position in relation to the surrounding and physical features, many of which will have an impact on the se ttlement’s type, size and function.
However, the importance of many of t he factors explained before diminish over time as technological advances enable people to overcome difficulties.
For example, a modern settlement does not need to be close to a river because drinking water is now piped to our homes and waterways are no longer important for transport.
LINEAR SETTLEMENTS:
•Linear settlement patterns can be considered special cases of point pattern distributions that vary in one dimension as points along a line.
•Linear settlement patterns are generally associated with linear features, either natural or human built. •Linear feature in nature that may influence settlement patterns include water courses- Shorelines, canyons, ridge-tops and boundaries between environmental zones.
•Built of defined linear features associated with linear settlement patte rns including roads and rails,
canals and even political boundaries.
•Development and expansion of linear settlement patterns is not restricted to points directly on or adjacent to linear feature.
The sectors of a linear city would be:
•a purely segregated zone for railway lines,
•a zone of production and communal enterprises, with related scientific, technical and educational institutions,
•a residential zone, including a band of social institutions, a band of residential buildings and a
"children's band",
•a park zone, and
•An agricultural zone with gardens and state-run farms (sovkhozy in the Soviet Union).
•As the city expanded, additional sectors would be added to the end of each band, so that the city
would become ever longer, without growing wider.
•The linear city design was first developed by Arturo Soriay Mata in Madrid, Spain during the 19th century.
•Promoted by the Soviet planner Nikolay Alexandrovich Milyutin in the late 1920s.
•The linear city has no central core around which the city grows, The city gr ows along a transport line or parallel transport lines.
•The city is characterized by High-density settlements on either side of the tr ansport line and especially near transport stops.
•Behind the Dense settlements is a band o f medium dense development with the rural area orgreen
area immediately behind this medium dense settlement.
•The kinds of development near the transport stops and along the transport lines are mixed use
settlements comprising of residential, commercial, production and services.
Arturo Soriay Mata linear city in Madrid, Spain ADVANTAGES:
•High accessibility
•Useful along the limited edge DISADVANTAGES: •Very sensitive to blockage requires control of growth •lacks focus,
•The choice of connection or of direction of movement are much less.
RADIAL (CIRCULAR) SETTLEMENTS:
In this type, a number of streets converge on one center which may be a source of water (pond, well), a temple or mosque, a center of commercial activity or simply an open space. Thus, the streets seem to be radiating from a common center. Rural Examples are settlements near Gurushikar, Mount Abu in
Rajasthan, Vindhyachal in Uttar Pradesh, etc. Examples- Amsterdam, Washington DC, et c.
Advantages: A direct line of travel for centrally directed flows Economics of a single centralized te rminal or origin point.
Disadvantages: Central congestion Local flow problems. Difficult building sites.
•An organization of streets that lie per pendicular to one another, the grid is among the most controlled of settlement patterns.
•The square or rectangular plots which the grid defines exercise a discipline upon the form of buildings
within its compass.
•Grid plans are rarely the result of social imperatives within the vernacular cultures, but are almost invariable imposed.
•Uniform ‘modules’ of plots and buildings on grid plans have been traced in t he Indus valley from the
3rd millennium B.C.
•Grid plans have extensively adopted by planners to regularized and contain the world’s squatter
settlements of the late-20th century.
•Efficiency in the use of public land, minimizing of street lengths, t he provision of sites and services,
sewage disposal and electricity supply are among the eco nomic arguments of modern grid planning policies.
Advantages: High accessibility minimum distribution of flow expansiion flexibility exc ellent physco logical orientation adaptability to level or moderately terrain
Disadvantages: Requires flow hierarchies. Limied in its adpatabilty to the terrain. Potentially monotonous.
MULTI CENTERED SYSTEM:
Advantages:
•Optional locations for focal activities and system terminals •Good psychological orientation
•Adaptability to existing conditions.
Disadvantages:
•Depends on stability to key point.
•Potential accessibility problems. •Tendency to dilute focal activities.
Examples- Rome
URBAN GROWTH:
Urbanization occurs naturally from individual and corporate efforts to reduce t ime and expense in commuting and transportation while improving opportunities for jobs, education, housing, and transportation.
•Living in cities permits individuals and families to take advantage of the opportunities of proximity,
diversity, and marketplace competition.
•People move into cities to seek economic opportunities.
• A major contributing factor is known as "rural flight". In rural areas, often on small family farms, it is
difficult to improve one's standard of living beyond basic sustenance.
•Farm living is dependent on unpredictable environmental conditions, and in times of drought, flood or pestilence, survival becomes extremely problematic.
•In modern times, industrialization of agriculture has negatively affected the economy of small and
middle-sized farms and strongly reduced the size of the rural labor market.
•Cities, in contrast, are known to be places where money, services and wealth are centralized. Cities are
where fortunes are made and where social mobility is possible.
Businesses, which generate jobs and capital, are usually located in urban areas. Whether the source is trade or tourism, it is also through the cities that foreign money flows into a country. It is easy to see why someone living on a farm might wish to take their chance moving to the city and trying to make enough money to send back home to their struggling family.
•There are better basic services as well as other specialist services t hat aren't found in rural areas. •There are more job opportunities and a greater variety of jobs. Health is another major factor.
•People, especially the elderly are often forced to move to cities where there are doctors and hospitals that can cater for their health needs. Other factors include a greater variety of entertainment
(restaurants, movie theaters, theme parks, e tc.) and a better quality of education, namely universities.
•Due to their high populations, urban areas can also have m uch more diverse social communities
allowing others to find people like them when t hey might not be able to in rural areas.
•These conditions are heightened during times of change from a pre-industrial society to an industrial one.
• It is at this time that many new commercial enterprises are made possible, thus creating new jobs in
cities. It is also a result of industrialization that farms become more mechanized, putting many laborers out of work. This is currently occurring fastest in India.
URBAN PROBLEMS - URBAN DECAY:
•The deterioration of the urban environment. It occurs w hen urban infrastructure falls into disrepair
and buildings are left empty for long periods of t ime.
Slum housing - with outside toilets, overcrowding, no hot w ater or central heating
Many buildings have been poorly built and now have leaking roofs, draughty windows and crumbling stonework
Empty buildings are vandalised; gap sites where buildings have been knocked down turn into derelict land
As the factories and housing have been in the same areas air, noise and water pollution have been common There have been a number o f schemes to reduce the problems of urban decay. They have had mixed success.
COMPREHENSIVE REDEVELOPMENT
This is when you knock down all the buildings and start from scrat ch. It was felt to be needed in some places as the problems were so bad. In Kingston and the Gorbals in Glasgow, for example, the old tenements were knocked down and replaced by new flats and multi-storey high rise buildings. Unfortunately, many of the new buildings were poorly built and have also bee n knocked down. This approach has also been criticised as it destroyed the social fabric of the area - people no longer knew their neighbours and they were moved away from their friends and relations.
URBAN REGENERATION
Another idea was to renovate the existing housing and improve the environment and economy. This Involves
• New roofs
• Secure entry-phone systems on tenement closes
• The outsides of tenements were cleaned by sand-blasting • Combining two small flats into a larger one
• Improving the environment by landscaping
• Building or improving the social facilities such as clubs and medical centres

GARDEN CITY – SIR EBENEZER HOWARD
• Most potent planning model in Western urban planning
• Created by Howard in 1898 to solve urban and rural problems • Source of many key planning ideas in the 20th century
Garden City‟ – an impressive diagram of THE THREE MAGNETS namely the town magnet, country magnet with their advantages and disadvantages and the third magnet with attractive features of both town and country life.
Naturally people preferred the third one namely Garden City.
A Garden City is a holistically planned settlement which enhances the natural environment and provides high-quality social housing and local jobs in a beautiful, healthy place with diverse communities. The Garden Cities were among the first manifestations of sustainable development by providing not only individual opportunities for local food or energy production but also the fair distribution of community assets. The Garden City principles are designed as an indivisible and interlocking framework for the delivery of high quality places.
Land value capture for the benefit of the community:
A distinguishing characteristic of the Garden City is the fair distribution to the community of the profits that result from new development. Capturing rising land values created by the development of the town can repay infrastructure costs and provide a portfolio of assets which are proactively managed in
perpetuity for the benefit of the Garden City community. This requires the acquisition of land at, or near, current use value by a body with effective planning and land assembly powers. Ideally, this requires a Development Corporation which could be led by a local authority. Access to compulsory purchase powers is crucial as a power of last resort for such bodies. The development of land is one major source of asset values and income but the control of core utilities and, in particular, local energy companies, provides significant opportunities for capturing values and securing genuinely localised and resilient economies.
Strong vision, leadership and community engagement:
If Garden Cities are to be successful, they need strong political support and leadership, with a clear vision and firm commitment. This commitment should be made as early as possible in the planning process to provide reassurance and cert ainty for all parties. Both the designation process and the development of the Garden City should demonstrate a real commitment to community participation. Such participation must be set within the c ontext of the needs of people already living in the area and those in the wider community who need a home. New Garden Cities require the very best of
professional expertise. If a local authority decides to pursue the development of a new Garden City or Suburb, it will need a dedicated planning and delivery te am with the right skills and expertise.

a surrounding belt of countryside to prevent sprawl, well connected and biodiversity rich public parks, and a mix of public and private networks of well-managed, high-quality gardens, tree-lined streets and open spaces. Garden Cities offer the opportunity to be highly climate resilient through extensive green and blue infrastructure. They must also demonstrate the highest standards of technological innovation in zero carbon and energy positive technology to reduce the impact of c limate emissions.
Strong local cultural, recreational and shopping facilities in walkable neighbourhoods:
Garden Cities are places of cultural diversity and vibrancy with design contributing to sociable
neighbourhoods. This means, for example, shaping design with the needs of children‟s play, tee nage interests and the aspirations of elderly in mind. Creating shared space s for social interaction and space for both formal and informal artistic activities, as well as sport and leisure activities.
Integrated and accessible transport systems:
Walking, cycling and public transport should be the most attractive and prioritised forms of transport in the garden city. This means ensuring a comprehensive and safe network of footpaths and cycleways throughout the development, and public transport nodes within a short walking distance of all homes. Where car travel is necessary, consideration should be made of shared transport approaches such as car clubs. New Garden Cities should be located only where there are existing rapid public transport links to major cities, or where real plans are already in place for its provision.
A strategic approach:
Ebenezer Howard saw the development of Garden Cities as part of a wider strategic approach to
meeting the nation‟s housing needs. This was based on networks of new settlements well connected by public transport. A national policy for a new generation of Garden Cities should consider how these settlements contribute to the nation as whole; how they relate to aspirations for a more balanced economy; to long term climate resilience, and to new opportunities in industrial modernisation.
GEDDISAIN TRIAD- PATRICK GEDDES
Geddes drew on circular theory of geographical locations presenting environmental limitations and opportunities that in turn determine the nature of work. His central argument was that physical geography, market economics and anthropology were related, yielding a “ single chord of social life all three combined”. Thus the interdisciplinary subject of sociology was developed into the science of
“man‟s interaction with a natural environment: the basictechnique was the regional survey, and the improvement of town planning the chief practical application of sociology".
Geddes writing demonstrates the influence of these ideas on his theories of the city. He saw the city as a series of common interlocking patterns, "an inseparably interwoven structure", akin to a flower. He criticised the tendency of modern scientific thinking to specialisation.
Against a backdrop of extraordinary development of new technologies, industrialisation and urbanism, Geddes witnessed the substantial social consequences of crime,
illness and poverty that developed as a result o f modernisation. From Geddes' perspective, the purpose of his theory and understanding of relationships among the units of society was t o find an equilibrium among people and the environment to improve such conditions.
Key ideas
"Conservative surgery" versus the gridiron plan
Geddes championed a mode of planning that sought to consider "primary human needs" in every intervention, engaging in "constructive and conservative surgery" rather t han the "heroic, all of a piece schemes" popular in the nineteenth and early twentieth centuries. He continued to use and advocate for this approach throughout his career.
Very early on in his career Geddes demonstrated the practicality of his ideas and approach. In 1886 Geddes and his newly married wife purchased a row of slum tenements in James Court, Edinburgh, making it into a single dwelling. In and around this area Geddes commenced upon a project of "conservative surgery": "weeding out the worst of the houses that surrounded them…widening the
narrow closes into courtyards" and thus improving sunlight and airflow. The best of the houses were kept and restored. Geddes believed that this approach was both more economical and more humane. In this way Geddes consciously worked against the t radition of the "gridiron plan", resurgent in colonial town design in the 19th century:
“The heritage of the gridiron plans goes back at least to the Rom an camps. The basis for the grid as an
enduring and appealing urban form rests on five main characteristics: order and regulatory, orientation in space and to elements, simplicity and ease o f navigation, speed of layout, and adaptability to
circumstance.”
However, he wished this policy of "sweeping clearances" to be recognised for what he believed it was: "one of the most disastrous and pernicious blunders in the chequered history of sanitation".
EVOLUTION AND CONCEPTUALIZATION OF THE NEIGHBORHOOD UNIT
The „neighborhood unit‟ as a planning concept evolved in response to the degenerated environmental
and social conditions fostered as a consequence of industrial revolution in the early 1900s. One of the
Arthur Perry (1872-1944), a New York planner. Perry‟s neighborhood unit concept began as a means of
insulating the community from the ill-effects of burgeoning sea of vehicular traffic. However, it evolved to serve a much broader purpose of providing a discernible identity for the concept o f the
neighborhood, and of offering to designers a framework for disseminating the city into smaller subareas. While the origin of the concept o f the neighborhood unit may be cited at an early date, it was the
publication of Clarence A. Perry‟s memorandum entitled „The Neighborhood Unit‟ in the 1929 „Regional Plan of New York and Its Environs‟, which led to its promotion as a planning tool. Perry‟s
monograph offered in concrete terms a diagrammatic model of the ideal layout for a neighborhood of a specified population size. This model provided specific guidelines for the spatial distribution of
residences, community services, streets and businesses.
Perry described the neighborhood unit as that populated area which would require and support an elementary school with an enrolment of between 1 ,000 and 1,200 pupils. This would mean a population of between 5,000 and 6,000 people. Developed as a low density dwelling district with a population of 10 families per acre, the neighborhood unit would occupy about 160 acres and have a shape which would render it unnecessary for any child to walk a distance of more t han one-quarter mile to school. About 10 percent of the area would be allocated to recreation, and through traffic arte ries would be confined to the surrounding streets, internal streets be ing limited to service access for residents of the
neighborhood. The unit would be served by shopping facilities, churches, and a library, and a community center, the latter being located in conjunction with the school (Gallion, 1984). Perry outlined six basic principles of good neighborhood design. As may be understood, these core principles were organized around several institutional, social and physical design ideals.
Basic principles
Size : 5000 population ( 1 school), 160 acre (area for one unit neighborhood). Border : the function of main road around neighborhood unit is as a border . Free area : 10% provide as free area.
Road network system: design as to prevent short road (prevent from across neighborhood unit). Hierarchy of road width is 132 feet, 100 ft, 66ft, 50 ft, and 40 ft)
Density: rough density for this system is about 5 unit house for every acre.
Major arterials and through traffic routes should not pass through re sidential neighborhoods. Instead these streets should provide boundaries of the neighborhood
Interior street patterns should be designed and constructed through use of cul-de-sacs, curved layout and light duty surfacing so as to e ncourage a quiet, safe and low volume traffic movement and
preservation of the residential atmosphere
The population of the neighborhood should be that which is required to support its elementary school The neighborhood focal point should be the elementary school centrally located on a common or green, along with other institutions that have service areas c oincident with the neighborhood boundaries The radius of the neighborhood should be a maximum of one quarter mile thus precluding a walk of more than that distance for any elementary school child
Shopping districts should be sited at the edge o f neighborhoods preferably at major street intersections.
CHANDIGARH PLANNING CONCEPTS - LE CORBUSIER
CHANDIGARH was the first planned city after independence from British rule in 1947. It is t he capital city of the states of Punjab and Haryana.
The city is located at the picturesque junction of foothills of the Himalayas Mountain range and the Ganges plains.
It houses a population of 1,054,600 inhabitants (2001) and is one of the richest cities of the nation. American architects Albert Mayer and Mathew Novicki were the first architects to be appointed for the project. After the death of Novicki in 1950, Le Corbusier was commissioned.
BASIC PLANNING CONCEPTS
The city plan was conceived as post war „Garden City‟ wherein vertical and high rise buildings were
ruled out, keeping in view the living habits of the people. Le Corbusier conceived the master plan of Chandigarh as analogous to human body, with a clearly defined
Head (the Capitol Complex, Sector 1), Heart (the City Centre Sector-17),
Lungs (the leisure valley, innumerable open spaces and sector greens), Intellect (the cultural and educational institutions),
Circulatory system (the network of roads, t he 7Vs) and Viscera (the Industrial Area).
The primary module of city‟s design is a Sector, a neighborhood unit of size 800 meters x 1200 meters. Each SECTOR is a self-sufficient unit having shops, school, health centers and places o f recreations and worship.
The population of a sector varies between 3000 and 20000 depending upon the sizes of plots and the topography of the area.
Layout of a typical residential sector
The Leisure Valley is a green sprawling space extending North-East to South-West along a seasonal riverlet gradient and was conceived by Le Corbusier as the lungs of the city. Apart from large Public Parks and special Botanical Gardens, it houses series of Fitness Trails, amphitheatres and spaces for open-air exhibitions.
The Central Sector of the city, Sector 17, is the main Public Congregation area of the city. It houses all major Shopping Complexes, Sports Facilities and Congregation Spaces.
The Basic Building Typology is observed as extremely Rectilinear with similar pr oportions. the smaller individual Residential Units are arranged around central common Green Spaces, although t he shapes are different.

ISSUES IN CONTEMPORARY URBAN PLANNING IN INDIA
Globalization and its impact on cities – Urbanisation, emergence of new forms of developments – self sustained communities – SEZ – transit development – integrated townships – case studies.
Urban renewal is a program of land redevelopment .
Urban renewal involves the relocation of businesses, the demolition of structures, the relocation of people, and the use of eminent domain (government purchase of property for public purpose) as a legal instrument to take private property for city-initiated development projects.
Over time, it has evolved into a policy based less on destruction and more on renovation and investment
The term Urban renewal means rebirth or regeneration of a city or a part of it which has been plagued by the ills of urbanization
• The planning concept originated in England and America. • Decayed parts of the city were demolished and rebuilt.
• These programs were thrust upon the city and its people and were criticized and halted on opposition by organized community movements.
• The urban renewal programs taken up later, involved greater participation of the communities • Key aspects -sustainability and inclusiveness
INDIAN CONTEXT
• Indian cities have a history that dates back to centuries
• In the last century cities faced a major unprecedented force of urbanization which ripped them • They have grown exponentially
• Their administration has not been able cope up with rapid urbanization
• The age old infrastructure is weakened and decayed leading to degeneration of the core areas in the city.
• Cities which have survived centuries are now at critical stage. • Concept of Urban Renewal – To provide life to the dying city.
WHY URBAN RENEWAL? The
triggers:-➢ Effective functioning of Administrative towns
o ( state HQ, District HQ)
➢ To accommodate an event of magnitude.
o (Asian games, Common Wealth Games in Delhi, Tri Centenary Celebrations of
consecration of the Guru Granth Sahib at Nanded)
➢ Necessity due to natural /man-made calamity
➢ (Earthquake in Bhuj, Plague in Surat)
➢ Obsolescence of land uses
➢ (Shifting of manufacturing industries )
➢ Market driven change of land use
o (Commercialization of Girgaum,Parel areas of Mumbai) ➢ To conserve historic monuments/ environment.
➢ ( Areas around theTaj mahal precinct ) Urban renewal is required for
• Dilapidating, ageing parts of the city, not providing the city its full potential and becoming a health hazard
• In built form it consists of old area of the city, congested area around transit points, illegal settlements needing redevelopment
• In terms of infrastructure - measures for efficient and smooth movement of traffic, improvement of transportation network, provision /improvement of utilities.
JNNURM
• In India the need to infuse vibrancy and rejuvenate cites was recognized in 2005 and the Central Government launched the Jawaharlal Nehru National Urban Renewal Mission (JNNURM)
• Launched to encourage cities to initiate steps for bringing phased improvements in their civic service levels
• Initiative to redevelop towns and cities by developing infrastructure, carrying out municipal reforms and providing aid to the state governments and the urban local bodies (ULBs)
in land use transformation
EFFECT OF CHANGE OF LAND USE Thane experience
The city had an economic base in the industrial estate and industries along its periphery. However with passing years there is a decline in the manufacturing sector and shift towards service sector. Thus of industrial land was converted to residential
Mulund experience
A change of land use was witnessed in 90s along LBS Road in the area between Mulund and Thane. Most of these industries shifted out and land was converted to residential. The new development consists of shopping malls and high end residential apartments. T.Nagar,

INTEGRATED TOWNSHIP
Large cities are getting over-crowded under the relentless march of urbanization. An estimated 160 million peoplehave moved to India’s cities in the last two decades, and another 230 million are
projected to move there within the next 20 years. The exponential rise in the number of city dwellers is leading to an ever-increasing demand for housing and urban infrastructure. At the same time, the
massive influx of people has strained India’s urban systems to the point of breaking down, creating
massive slums with inadequate housing, sanitation, basic services and security. The 2011 census
indicates that there are 14 million households (or approximately 70 million people assuming an average
household size of five people) living in slums in India’s cities.
To cope with this demographic pressure, all our bigger cities are stretching their boundaries. The
extension of the traditional city limit is spurred in large measure by the expansion in real estate activity to accommodate the bulge in population. Even the new maste r plans for all major cities are being rejigged to facilitate the expansion of city limits.
To ease the pressure on big cities and improve the quality of urban living, town planners and
policymakers are encouraging the setting up of integrated townships as an effective development tool for building infrastructure in the newly marked spaces beyond traditional city boundaries. Setting up of self-contained integrated townships in a decentralized manner offers a sensible solution to providing a more holistic living environment and preventing the proliferation of unplanned urban villages. In fact, integrated townships bring a raft of value propositions such as affordability, convenience, and a relaxing lifestyle in one very attractive package to modern urban planning and development
Integrated Townships : Fitting in the Smart City Model for India
An area of utmost importance which is see ing major policy boost is provision of sustainable cities
through the model of Integrated Townships. This model fits the g reenfield development category of the recently announced Smart City development plan (more than 250 acres). Four states of India –
Karnataka, Maharashtra, Gujarat and Rajasthan have announced their Inte grated Township Policies. The question here is – Can these Integrated Townships bring about the necessary change required and act as spark for initiating and sustaining urban development? Will they be able to contribute towards integrated – sustainable urban development?
As per Government, “Integrated Township includes housing, commercial premises, hotels, resorts, city
and regional level urban infrastructure facilities such as roads and br idges and mass rapid transit systems. Development of core and allied infrastructure forms an integrated part of township
licensed developer/firm/company, together with workplace and places o f residence with all attendant facilities and amenities in such township and in accordance with the rules.
Township is a community living platform where the concept of walk-to-work can be implemented, everything that families need is in close proximity from t heir homes – shopping malls, entertainment options, hotels, hospitals, schools, offices, etc. Integrated here means –comprehensive in scope and scale; Connected features, services and amenities; Sustainable and Self-sufficient.
Test of sustainability of a city is based on a few parameters as per Wheeler (1998) - Compact; Efficient Land use; Less Automobile use, yet bette r access; Efficient Resource use, less pollution and waste; Restoration of natural systems; Good housing and living environments, healthy social ecology; Sustainable economy; Community participation and environment; Preservation of local culture and wisdom.
The planning concepts of New Integrated Townships may include : Community building -“Design for People”; Economic Opportunities – “Live in Cities also Work”; Traffic and road management – “Design for well managed roads for both c ars and people”; Physical Infrastructure – “Well Designed and
Managed services can Make or Break a City”; Social Infrastructure – “Citizens need to Learn Interact, Play and Share”; Security – “A Safe City is a Happy City”; Sustainability (Ecological, Financial and
Maintenance) – “Build Townships for next generation”.
Features of townships that should lead to sustainable urban development (i) Green Housing and Nature Friendly
(ii) Energy Efficient Habitat
(iii) Integrated Waste management (iv) World Class Infrastructure (v) Walk, Work and Play concept (vi) Walk, Work and Play concept (vii) Economies of Scale
(viii) People’s Participation
(ix) Government in Surplus (x) Foreign Direct Investments
(xi) Clubs ‘New Urbanism’ and ‘Garden City’ Movements
(xii) Fully Featured and Self Sufficient (xiii) Adequate Open Green Spaces (xiv) Community Experience
(xv) Suburban Greenfield development opportunity The aspects of integrated townships that need a n extra caution
(i) Gated Communities
(ii) Islands of world-class infrastructure in the midst of poverty struck city (iii) Parking places for money
