Understanding Urban Areas & Growth
Understanding Urban Areas & Growth
1. All places with a municipality, corporation, cantonment board or notified town area committee,
etc.
2. All other places which satisfied the following criteria:
b. At least 75 per cent of the male main working population engaged in non-
agricultural pursuits; and
The first category of urban units is known as Statutory Towns. These towns are notified
under law by the concerned State/Union Territory (UT) Government and have local bodies like
municipal corporations, municipalities, etc., irrespective of their demographic characteristics
as reckoned on 31st December 2009. Examples: Vadodara (M Corp.), Shimla (MCorp.) etc.
The second category of Towns (as in item 2 above) is known as Census Town. These were
identified on the basis of previous census data (for 2011 census 2001 census data would be
used).
Urban Growth The (relative or absolute) increase in the number of
people who live in towns or cities. The pace of urban population growth
depends on the natural increase of the urban population gained by urban
areas through both net rural-urban migration and the reclassification of
rural settlements into cities and towns.
Urban areas are created and further developed by the process of urbanization. Urban
areas are measured for various purposes, including analyzing population density and
urban sprawl.
Urban sprawl
The meaning of Urban sprawl is also taken in a way for causing environmental
degradation, and intensifying segregation and undermining the vitality of existing urban
areas and attacked on aesthetic grounds. The term has become a rallying cry for
managing urban growth.
Despite these urban uses, the fringe remains largely open with the majority of the land
agricultural, woodland or other rural use. However the quality of the countryside around
urban areas tends to be low with severance between areas of open land and badly
maintained woodlands and hedgerows.
In this case, peri-urbanisation is seen as the expansion of functional rural—urban
linkages such as commuting.
Urban fringe
The urban fringe, or rural-urban fringe also known as the outskirts or the urban
hinterland, can be described as the "landscape interface between town and
country", or also as the transition zone where urban and rural uses mix and often
clash. Alternatively, it can be viewed as a landscape type in its own right, one forged
from an interaction of urban and rural land uses.
Its definition shifts depending on the global location, but typically in Europe, where
urban areas are intensively managed to prevent urban sprawl and protect agricultural
land, the urban fringe will be characterised by certain land uses which have either
purposely moved away from the urban area, or require much larger tracts of land.
Despite these 'urban' uses, the fringe remains largely open, with the majority of the
land agricultural, woodland or other rural use. However, the quality of the countryside
around urban areas tends to be low.
The word rural has been defined as “living in the country having the standing
qualities or manner of peasants of country folk, engaged in country occupation
agricultural or pastoral, or pertaining to, or characteristic of the country or country
life as opposed to the town”. Rural urban fringe is a complex zone on the
periphery of a growing urban area. Rural-urban Fringe is a zone rather than a
boundary. Hence, the rural-urban fringe cannot be precisely demarcated.
Rural-urban differentiation can be examined in several aspects, for example,
occupational difference, environmental differences, differences in the nature of
housing and house holding, difference in the density of population, difference in
social mobility and migration and the differences in social interaction and
stratification.

Settlement
A settlement, locality or populated place is a community in which people live. A
settlement can range in size from a small number of dwellings grouped together to the
largest of cities with surrounding urbanized areas. Settlements may include hamlets,
villages, towns and cities. A settlement may have known historical properties such as the
date or era in which it was first settled, or first settled by a particular people.
In the field of geospatial predictive modeling, settlements are also are defined as "a city,
town, village or other agglomeration of buildings where people live and work."
A settlement conventionally includes its constructed facilities such as roads, enclosures,
field systems, ponds, parks and other public places.
Urban morphology
Urban morphology is the study of the form of human settlements and the process of
their formation and transformation. The study helps in understanding the spatial
structure and character of a metropolitan area, city, town or village by examining the
patterns of its component parts and the ownership or control and occupation.
Typically, analysis of physical form focuses on street pattern, plot pattern and
building pattern, sometimes referred to collectively as urban grain. Analysis of specific
settlements is usually undertaken using cartographic sources and the process of
development is deduced from comparison of historic maps.
(Cartography is the study and practice of making maps)
Infrastructure
Infrastructure is the fundamental facilities and systems serving a country, city, or
other area, including the services and facilities necessary for its economy to function.
Infrastructure is composed of public and private physical improvements such
as roads, bridges, tunnels, water supply, sewers, electrical grids, telecommunication
(including Internet connectivity and broadband speeds). In general, it has also been
defined as "the physical components of interrelated systems providing commodities and
services essential to enable, sustain, or enhance societal living conditions."
There are two general types of ways to view infrastructure, hard or soft. Hard
infrastructure refers to the physical networks necessary for the functioning of a modern
industry. This includes roads, bridges, railways, etc. Soft infrastructure refers to all the

Built environment
The term built environment, or built world, refers to the human-made
surroundings that provide the setting for human activity, ranging in scale from buildings
to parks. It has been defined as "the human-made space in which people live, work, and
recreate on a day-to-day basis."
The "built environment encompasses places and spaces created or modified by people
including buildings, parks, and transportation systems."
Currently, built environments are typically used to describe the interdisciplinary field
that addresses the design, construction, management, and use of these man-made
surroundings as an interrelated whole as well as their relationship to human activities
over time.
City centre
A city centre is the commercial, cultural and often the historical, political and
geographic heart of a city, especially those in the Western world. The term "city centre"
is primarily used in British English. In North America, the term downtown is used.
A Central Business District (CBD) is the commercial and business centre of a city.
In larger cities, it is often synonymous with the city's "financial district". Geographically,
it often coincides with the "city centre" or "downtown", but the two concepts are
separate: many cities have a central business district located away from its commercial
or cultural city centre or downtown.
The CBD is often also the "city centre" or "downtown", but this is also often not the
case. Midtown Manhattan is the largest central business district in New York City and
in the world; yet Lower Manhattan, commonly called Downtown Manhattan,
represents the second largest distinct CBD in New York City and is geographically
situated south of Midtown.
For example, London's "city centre" is usually regarded as encompassing the
historic City of London and the medieval City of Westminster, whereas the City of
London and the transformed Docklands area are regarded as its two CBDs.
Mexico City also has a historic city centre, the colonial-era Centro Histórico, along with
two CBDs: the mid-late 20th century Paseo de la Reforma - Polanco, and the new Santa
Fe.
In Taipei, Taiwan, the area around its main railway station is regarded as the historic
city centre while the Xinyi Planned Area located to the east of the said railway station
is the current CBD of Taipei, being both the financial district and the premier shopping
area.
The shape and type of a CBD almost always closely reflect the
city's history. Cities with strong preservation laws and maximum
building height restrictions to retain the character of the historic
and cultural core will have a CBD quite a distance from the center of
the city. This is quite common for European cities such
as Paris or Vienna.
In cities in the New World that grew quickly after the invention of
mechanized modes such as road or rail transport, a single central
area or downtown will often contain most of the region's tallest
buildings and act both as the CBD and the commercial and cultural
city centre.
Satellite town
A satellite town or satellite city is a concept in urban planning that refers essentially
to smaller metropolitan areas which are located somewhat near to, but are mostly
independent of larger metropolitan areas.
Satellite cities are small or medium-sized cities near a large metropolis, with
characteristics that:
Some satellite cities that are particularly close or well connected to their larger
neighbors and/or have their own historic downtown may also qualify as the uptown
variety of edge cities, but the terms are not synonymous.
Multi-polar cities
In some cases large metropolitan areas have multiple centers of close to equal
importance. These multi-polar cities are often referred to as twin cities. Multi-polar
cities differ from satellite cities in such cases :
satellites are clearly much less important than the larger center around which they
are located, while the various nodes of multi-polar cities are close to each other in
importance
satellites are separated from the larger center by a substantial belt of rural territory,
while twin cities may be fully integrated in physical form
Generally speaking, cities that are listed as being part of the same urbanized area should
be considered twins, rather than one having a satellite relationship to the other.
Metropolitan areas
Conceptually, satellite cities are miniature metro areas on the fringe of larger ones.
Satellite cities are sometimes listed as part of the larger metro area, and sometimes
listed as totally independent. In the United States, satellite cities are often (but not
always) listed as independent Metropolitan Statistical Areas within a single Combined
Statistical Area that is unified with the larger metropolis.
Definitions:
Towns: For the Census of India 2011, the definition of urban area is as follows;
1. All places with a municipality, corporation, cantonment board or notified town area
committee, etc.
2. All other places which satisfied the following criteria:
i) A minimum population of 5,000;
ii) At least 75 per cent of the male main working population engaged in
non-agricultural pursuits; and
iii) A density of population of at least 400 persons per sq. km.
The first category of urban units is known as Statutory Towns.
These towns are notified under law by the concerned State/UT Government and have
local bodies like municipal corporations, municipalities, municipal committees, etc.,
irrespective of their demographic characteristics as reckoned on 31st December 2009.
Examples: Vadodara (M Corp.), Shimla (M Corp.) etc.
The second category of Towns (as in item 2 above) is known as Census Town. These
were identified on the basis of Census 2001 data.
Population of UAs/Towns:
1. The total urban population in the country as per Census 2011 is more than 377 million
constituting 31.16% of the total population.
2. Class I UAs/Towns: The UAs/Towns are grouped on the basis their population in
Census. The UAs/Towns which have at least 1,00,000 persons as population are
categorised as Class I UA/Town. At the Census 2011, there are 468 such UAs/Towns.
The corresponding number in Census 2001 was 394.
3. 264.9 million persons, constituting 70% of the total urban population, live in these
Class I UAs/Towns. The proportion has increased considerable over the last Census. In
the remaining classes of towns the growth has been nominal.
4. Million Plus UAs/Towns: Out of 468 UAs/Towns belonging to Class I category, 53
UAs/Towns each has a population of one million or above each. Known as Million Plus
UAs/Cities, these are the major urban centres in the country. 160.7 million persons (or
42.6% of the urban population) live in these Million Plus UAs/Cities.18 new UAs/Towns
have been added to this list since the last Census.
5. Mega Cities: Among the Million Plus UAs/Cities, there are three very large UAs with
more than 10 million persons in the country, known as Mega Cities. These are Greater
Mumbai UA (18.4 million), Delhi UA (16.3 million) and Kolkata UA (14.1 million). The
Urban agglomeration
The population of a built-up or densely populated area containing the city proper / core
city, suburbs and continuously settled commuter areas or adjoining territory inhabited
at urban levels of residential density. Large urban agglomerations often include several
administratively distinct but functionally linked cities. For example, the urban
agglomeration of Tokyo includes the cities of Chiba, Kawasaki, Yokohama and others.
Howard attempted to study as an integrated entity the spatial organization and internal
dynamics between cities and their surrounding countryside. In his vision of the
urbanized landscape, the urban form is not only the areas occupied by cities but also an
area comprising several peripheral Garden Cities integrated with a Central City. This
concept eventually evolved into the early forms of the “Garden City” model of urban
agglomeration.
In 1915, the British sociologist and humanist urban planner Patrick Geddes published
his Cities in Evolution, based on his research on cities in the United Kingdom
(Geddes, 1915).
During this same period, newly emerging urban clusters could be identified in the
Greater Paris region of France, the Berlin-Ruhr region of Germany, the Pittsburg-
Chicago region of the United States and the Greater New York region of the United
States (Geddes, 1915).
Saarine suggested that the development of cities should follow the order from chaotic
concentration to ordered decentralization. The Greater Helsinki Master Plan was
based on this theory. Similar master plans started to appear in various countries,
suggesting that studies on urban clusters were attracting increasing attention.
One of the most important things that a developer does with raw land is bring roads
onto the site and connect those roads to the public right-of-way. Lots are usually located
adjacent to the new road and have direct access to it. If the subdivision remains private,
the homeowners will maintain the roads but often they’re deeded to the city and
maintained by the municipal service department. Undeveloped land is usually an area
that lacks the infrastructure, services and buildings that are often characterized as urban
development.
Land development is altering the landscape in any number of ways such as:
Road construction
Access roads, walkways and parking lots
Bridging
Landscaping
Clearing, terracing or land levelling
Setup of fences and, to a lesser degree, hedges
Service connections to municipal services and public utilities
Drainage, canals
External lighting (street lamps, etc.)
Landowner or developers on any size of project will often want to maximise profits,
minimise risk and control cash flow. This "profit enhancement" means identifying and
developing the best scheme for the local marketplace, whilst satisfying the local
planning process.
Usually, the first step is to have the land zoned as residential (or commercial, industrial,
or other), then it is surveyed and laid out in lots or parcels. Curbs are built, utility lines
installed, and streets are paved, then lots that have been sold are built upon. The land
that was once natural land is by this process developed.
A survey, if required
Hookup to utilities: phone, electric, cable, gas, and sewer and water (municipal or
community systems). Include both the cost to extend lines to your house and the
“tap fee” to hook up.
Septic system design and installation (conventional or alternative, if required)
Well drilling, pump, and hookup to house
IMPACT FEES
Impact fees are now assessed by many towns to help them pay for schools,
infrastructure, and other public costs associated with adding new homes to their
community. Depending on the state, they may be called development fees, mitigation
fees, service availability charges, facility fees, and other creative names.
The Urban Land Ceiling Act was a law in India, that was passed in 1976. This act
had a huge bearing on urban development, by barring development on large tracts of
available land. As a result, the act has already been repealed in some states, such
as Gujarat.
This act was repealed in November 2007 in the state of Maharashtra. The repeal was a
pre-condition to the state government with a grant under the Jawaharlal Nehru
National Urban Renewal Mission (JNNURM), to be used for
major infrastructure development projects (like the Mumbai Trans Harbour Link,
the Mumbai Metro Project, the Bandra-Worli, the Worli-Nariman Point sealink and
the Mumbai Urban Transport Project-II).
However, there is still considerable confusion in the process required for the clearance
of land for buildings; the repeal has not had much impact on the ground. The
Maharashtra Government has purchased large tracts of land under provisions of this
act, to be used to provide low-cost housing to the common people. However, this land
continues to lie vacant.
Unfortunately, this Act has led to a Lack of Managed Green Areas in cities which acts as
Lungs of the City and greater population density in developed areas as owners had to
sell off their excess Land to builders and the resultant corruption of Building
departments of Government Municipality.
The Act provided for imposition of a ceiling on both ownership and possession of vacant
land in urban agglomerations; acquisition of the excess vacant land by the state
government, with powers to dispose the vacant land for common good; payment of an
amount for the acquisition of the excess land; and granting exceptions in respect of
certain specific categories of vacant land.
This legislation fixed a ceiling on the vacant urban land that a ‘person’ in urban
agglomerations can acquire and hold. A person is defined to include an individual, a
family, a firm, a company, or an association or body of individuals, whether
incorporated or not. This ceiling limit ranges from 500-2,000 square metres (sq. m).
Excess vacant land is either to be surrendered to the competent authority appointed
under the Act for a small compensation, or to be developed by its holder only for
specified purposes. The government acquired any land owned in excess of the
prescribed limit by following a specific method of calculation, which was based on the
income the acquired land was able to generate.
The Act provides for appropriate documents to show that the provisions of this Act are
not attracted or should be produced to the registering officer before registering
instruments compulsorily registrable under the Registration Act.
Ceiling limit.—
(1) Subject to the other provisions of this section, in the case of every person, the ceiling
limit shall be,—
(a) where the vacant land is situated in an urban agglomeration falling within category A
specified in Schedule I, five hundred square metres;
(b) where such land is situated in an urban agglomeration falling within category B
specified in Schedule I, one thousand square metres;
(c) where such land is situated in an urban agglomeration falling within category C
specified in Schedule I, one thousand five hundred square metres;
(d) where such land is situated in an urban agglomeration falling within category D
specified in schedule I, two thousand square metres.
Informal builders provide the bulk of affordable housing and define large areas of our cities.
Originally created for those long considered as poor and unable to house themselves, over time the
resultant informal housing generally matches higher income standards. This incremental process
has been adopted by governments into programmes called ‘site and services’, focusing on housing
and land development, and embracing process as the key. A methodology to capture this process
has been developed which offers a base for developing effective policies in supporting the
incremental builders.
SYNOPSIS
The rapid urban population surge of the 60s driven largely from migration with resultant massive
unauthorized city expansion provided challenges in finding effective housing interventions.
Upgrading programs became widespread despite high monetary and spatial costs. This lecture
focuses on a mimic of the informal housing process which offered a direction for policy, adopted in
the 70s by development agencies worldwide and known as ‘site and services’. Difficulties and
unresolved challenges in these projects ended their attraction and they fell out of widespread use by
the mid 80’s. However, as credible studies indicated that urban population growth was expected to
double in the next 20 years, a ‘site and services’ approach has again recently become the option of
choice for housing intervention as one of the few proactive options available. After-the-fact ‘catchup’
policy of upgrading communities as the policy choice was no longer seen as sufficient.
Reinhard proposes that to learn from the successful informal developments as seen everywhere
around the world, and to tap their energy and resources, is providing a viable affordable option – this
pay-as-you-go process is a key way by which families succeed. However, the process takes a long
time, with a clear burden on the families. Safety concerns of proper construction and lack of
appropriate skills are challenges to the family-builders, particularly when additionally confronted with
effects from global climatic change. Longitudinal surveys of informal areas and the previous site and
services projects of the 70s offer a base for understanding the informal process and suggest areas
of necessary and successful intervention.
Reinhard argues that the focus should continue the shift to ‘starter core units’ that can be expanded
by owner energies, as they provide initial security and a frame for expansion, while also offering a
‘safe room’ for the increasing disasters from environmental change. A wide range of ‘starter’ options
are now available to fit specific situations, from single story units to multi-story expandable
apartments for increased densities. Support/guidance for densification of existing housing provides
an effective strategy for mitigating expensive urban sprawl. Standards need to be reoriented to
reflect and embrace an incremental, pay-as-you go process. Funding support, and technical
assistance needs to be reoriented. Infrastructure can also be developed incrementally, to parallel
growth and demands at both neighborhood and house scales.
In many Third World cities most poor families rent accommodation, elsewhere they are
forced to live in their ' own ' flimsy shelter. One relatively constant feature is that
housing in the countryside is generally worse than that in urban areas. There are no easy
solutions to the Third World's diverse housing problems because a lack of adequate
shelter is merely one manifestation of generalised poverty. Decent shelter for all can
never be guaranteed so long as there is widespread poverty. At the same time, sensible
policies can help mitigate shelter problems.
Making land more accessible, guaranteeing that building materials are not overpriced
and providing land with basic services would all help. Little is likely to be gained by slum
demolition because that simply increases the number of families requiring shelter. More
should be done to encourage the development of rental housing, especially where most
poor urban dwellers are tenants and where most landlords live in the same
accommodation themselves.
