Factors controlling landform development

June 26, 2021 by Bhushan Leave a Comment Last Updated June 26, 2021

Factors controlling landform development deals with processes and theories of exogenetic processes.

Order of relief

  1. First-order relief - Oceans and continents
  2. Second-order relief - Features on oceans and continents as a result of endogenetic processes
  3. Third-order relief - Features on oceans and continents and on second-order relief due to exogenetic processes.

Landforms are the products of many processes. Processes create and shape landforms.

Landforms and landscape are influenced by.

  1. Processes
    1. Exo - Climatic processes - decide the type and the intensity of the exogenetic process
    2. Endo - Internal heat
  2. Rock structure - the presence of folds fault joints slopes, rock composition mineral composition
  3. Relief and altitude - decide the effectiveness of the denudation process
  4. Time
  5. Biota - Man is a deciding factor

The way the factors combine and express themselves have been modelled through theories in geomorphology.

WM Davis

One of the earliest theory in landform development is WM Davis's. He is considered the father of geomorphology. His theory is called "the theory of landform evolution" or "the theory of geomorphic cycles".

Historical approach

Davisian approach was a historical approach with the objective of reconstructing the geological past of the landforms.

The historical approaches by nature will be speculative and based on certain simplifying assumptions. Davis and his historical approach were influenced by three concepts.

  1. Hutton's uniformitarianism - It is a principle in any historical study.
  2. Darwin's concept of gradual evolution - The concept of gradualism and evolutionary processes challenged the the concept of catastrophic revolutionary changes.
  3. Powell's concept of base level

Hutton's uniformitarianism

According to Hutton, "The processes that operate today with their consequences were also the processes that operated earlier and with the same consequences".

In other words, "The present is the key to the past". If we understand the processes that operate today, we can infer about the processes earlier and reason the consequences accruing them.

Charles and Lyell modification

later Charles and lyall modified the concept of uniformitarianism and and suggested that the processes that operate today also operated area but not necessarily with the same intensity or with the same degree of effect

uniformitarianism is also expressed as the processes operate as to there is no vistage of a beginning and no prospect of an end.

The influence of Darwin.

Darwin's gradualism and his concept of evolution was an alternative to catastrophism. Where he asserted things don't happen suddenly. Every event and its consequences is a part of very slow evolutionary processes with changes that operate through predictive and definite stages.

Davis while using darwinian concept of evolution asserted that time is an active factor. So division idea in the historical context is a time-dependent approach.

Davisian idea of 'cycle' as an orderly and sequential set of stages that operates gradually through time was influenced by Darwin.

Powell's concept of base level.

The base level of powell is essentially the sea level. According to Davis, Base level is the tendency and drive of the river to reach the base level that energizes the river that makes it an agent of erosion. The base level therefore is what operates the cycle of erosion of Davis.

Davis focuses on denudation and erosional processes. His model of landform evolution is based on the assumption that the base level is constant and cannot change. Namely, the cycle of erosion operates in conditions of prolonged crustal stability. Any possibility otherwise was considered as abnormal by Davis.

There are different types of base level.

  1. Global sea level / Mean sea level (MSL) - for a considerable length of time, the global sea level was considered unfluctuating. We assume a constant and constant climatic condition.
  2. Regional sea level - Sea level at countries and regions. In India, it is mean sea level at Chennai
  3. Local base level - average levels of water in the lakes into which smaller rivers drain into. The local base level is more amenable to fluctuation than the regional and global base level.
  4. Changing base level - may be related to tectonic processes or because of climatic processes.

Davisian model of Landform Evolution / cycle of erosion / Fluvial cycle of erosion

according to Davis landforms are product of structure process and stage.

structure

mineral composition presence of faults types of folds joints and cracks slope analysis relief and elevation.

  • relative rock hardness - differential erosion is due to relative rock hardness. Harder rocks higher elevation
  • Steeper slopes - can intensify erosion processes
  • high and steep elevation - Gorges
  • Soft sedimentary rocks - canyon
  • Rifting zone - preferable zones occupied by river valleys.

Process.

Stage

The following were the assumptions in Davisian Model

NoAssumptionsComments
1There exist a Flat Featureless Plain at the base level.he doesn't explain the origin and feature of this flat featureless plain
2 The flat featureless plane is subjected to rapid upliftment for a very short length of time. Thereafter he assumes a state of prolonged crystal stability with an unchanging base level-- This is the only reference that he makes for the internal endogenetic process.
3After upliftment completes erosion starts that shape the landforms into their features.-- His assumption that the erosion starts only after upliftment is over is criticized.
-- According to Davis, the main and only agent of erosion are rivers. Hence his theory is a fluvial cycle of erosion.
Assumptions in Davisian Model

Comments

much of Davis work was from the observations in the US with its humid temperate cool conditions where reverse dominate as the agents of denudation.

he considers these conditions as normal and generalizes it for the whole world. This technique of Davis is deductive reasoning which is scientific but there are always risks of oversimplification and over generalisation.

The following are the stage based changes due to cycle of erosion of the rivers

Youthful StageMature StageSenile Stage
small river at great height and the slope is steep.river is bigger.river is very large
the river is swift. The river performs the work of valley deepening/ vertical erosion.
The river is not capable of valley widening.
river is capable of both valley deepening and valley widening because of vertical cutting and also lateral cutting.
your submit living along with valley deepening.
Absolute relief producers relative relief initially increases and then starts to reduce
valley deepening slows and almost stops. Valley widening is the main process.
summit is lowered.
Both absolute relief and relative relief falling rapidly
River is very near the base level
features formed - gorge and v shaped valley.
the river cannot perform summit erosion because river cannot widen.
valley deepening and river lengthening are the two activities of the river. River lengthening is due to headward erosion. River capture occurs.
Pi rating river or beheaded river pirated river.
rectilinear profile.
The valley side profile and floor profile will become smooth and straight.
valley sides and floor concave profile. The cross section of valley side and valley floor is concave profile.
the valley floor is irregular with waterfalls rapid s.
The valley sites and valley floor are convex in profile.

In youthful stage the absolute relief is constant but the relative relief is increasing because of valley deepening.

Thalweg is longitudinal profile of the valley floor
the landscape is relatively flat with undulations with some resistant rocks scattered called monadnocks. This landscape is called as peneplain.
last stage in division cycle.
Artifical senile stage landscape will have large meandering rivers with oxbow lakes mart lake like wular lake of Jhelum.
Division model does not refer to any depositional landforms like deltas are floodplains.
Telangana peneplain.

Davis is implying that every high mountain and elevated feature will eventually become flat featureless plain as it evolves from youth towards senile stage.

The evaluation of davision theory.

  1. it is a new concept and first comprehensive model
  2. His historical approach is very innovative because he was able to bring in darwinian evolution
  3. The concept of stage and time as a factor of davision approach
  4. Slow development according to Davis is due to slope decline or down wasting. Where the slopes are seen to be the consequence of their age and stage of evolution.

Limitations

  1. this concept of Davis is not as refined as Pencks slope replacement model or king's slope retreat model.
  2. Detective reasoning concept is of gross generalisation
  3. He does not explain the role of other agents of denudation.
  4. He ignored endogenetic processes and only reference to internal process is rapid upliftment for a very short time and there after he assumes prolonged crystal stability namely the base level for Davis is unchanging. He considered to the possibility of other cycles and calls those as interruptions are partial cycles that disrupt the normal cycle of erosion
The base level changes may be positive toward the completion of cycle when the base level gets uplifted or negative when the base level positive change will shorten the cycle and the negative change will prolong the cycle. 

Negative changes in the base level that prolong the cycle mein start the second cycle of erosion. The river which was becoming old again becomes young. This is called river rejuvenation. Young youthful features will now get superimposed on the peneplain. 

Features of river rejuvenation. 
1. Entrenched valleys - incised valleys - valley within a valley.
2. River terraces - may be paired terraces or unpaired terraces. 
3. Meanders.
4. Knick point.
5. Delta. 

PENCK.

landforms are the manifestations of the exogenetic and the endogenetic processes.

Prima Rumph - To begin with, penck assumed there exist a flat featureless plain at or near the base level called prima rumph. He explains that prima rumph maybe tectonic or erosional surface.

prima rumph can go through the following 3 phases / entwicklung. But entwicklung need not follow one another sequentially through time.

Entwicklung

  • Aufsteigende (waxing) entwicklung
  • Gleimorphige (constant growth)
  • Absteigende (waning)

Aufsteigende (waxing) entwicklung.

  • landform undergoing very rapid accelerating upliftment
  • The rate of erosion is less than the upliftment rate
  • Summit erosion and valley deepening occurs
  • The rate of summit erosion is less than rate of valley deepening
  • Absolute and relative relief increasing at accelerated rate.

Gleimorphige.

  • summit erosion = valley deepening hence the relative relief remains constant but there are three sub possibilities
    • Rate of upliftment more than erosion
    • Upliftment equals rate of erosion - absolute or relative relief constant
    • Upliftment it is less than erosion - relative relief constant absolute relief decreases

Absteigende.

  • upliftment is less than erosion and almost stops
  • Summit erosion is more than valley deepening
  • Relative and absolute relief reducing
  • The land is flattening in this phase
  • The final feature in this phase is a gently sloping relative Lee flat with convexo concave profile - Boschens and Haldenhangs.

End rumph - The end rumph may have loose scattered resistant rocks called as in Inselbergs . Inselberg are not same as monadnocks. Monadnocks are senile stage feature with gentle sloping angles where are inselberg are isolated hills with vertical scarp faces. The process of insulin berg formation with its perpendicular faces can be explained according to pencks model. But it can be better explain by kings models sleep retreat and pediplanation.

graphical representation of pencks model.

Evaluation.

  1. time independent model
  2. Process theorist
  3. Accounts better for process and structures as control
  4. Rejects the idea of stage based changes
  5. Thanks model of slope development is called slope replacement which was earlier confused to be model of slope retreat. Slope retreat is a concept of l c king and not that of penck.

evaluation should be in the context of comparing with Davis.

5. Typology of agricultural regions/Agricultural regions of the world

March 30, 2021 by Bhushan Leave a Comment Last Updated March 30, 2021

Agricultural regions of the world

There are many ways of classifying and regionalizing agriculture. Some of the earliest schemes of agricultural crops ๐ŸŒพ are those based on agricultural productivity and crop combinations. Such regionalization for crop combination only reflects the type of land used but doesn't represent an agricultural system in all its diversity and components. Agriculture practiced is rarely the reflection of physical factors alone. Apart from the soil, rainfall๐ŸŒง๏ธ, temperature๐ŸŒก๏ธ, and slope consideration, the more important deciding factors are the technology, infrastructure, type of inputs, and techniques of farming.

Agricultural regions of the world

Derwent Whittlesey's Classification

Whittlesey, therefore, tried to suggest a more holistic basis of Agricultural regionalization accounting for the entire range of factors that can influence agriculture.

The following are 5 variables that he considered.

  1. Choice of Crops๐ŸŒพ
  2. Crop ๐ŸŒพ and Livestock ๐Ÿ–combination
  3. Degree of Mechanization ๐Ÿšœ
  4. Degree of Commercialization ๐Ÿ’ฐ
  5. Infrastructure and Buildings ๐Ÿข

Based on the above five factors,Derwent Whittlesey identified the following 13 agriculture types.

9. Human Development Index (HDI)

January 3, 2021 by Bhushan Leave a Comment Last Updated March 28, 2021

The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development.

  • A long and healthy life,
  • Being knowledgeable,
  • Have a decent standard of living.

The HDI is the geometric mean of normalized indices for each of the three dimensions.

The common objective of all development is to secure a better life in terms of amenities, a better quality of life, and prospects for all people and citizens.

Development in its more progressive and in its more modern concept is about securing people the following three.

Development is securing the following

  1. Better Quality of Life and a Better Standard of Living
  2. Dignity of life and Self-Esteem
  3. Better and more Democratic Choices across all aspects of life (Economic, Social, and Political)

Development - Classical Economics

Conventionally in the initial stages, Human development was centered around Economic Growth alone with an assumption that economic growth on its own can translate into better Social and Political outcomes. This is Classical Economics Wisdom.

Development in 1970s - Physical Quality of Life Index (PQLI)

In the 1970s under David Morris, the UN accepted development to be measured under (PQLI) Physical Quality of Life Index. This index ignored economic parameters and included achievements under Literacy, IMR, and Life Expectancy alone. This again is an incomplete measure because Income and Economy are important determinants of social sector achievements.

Development in 1990s - Human Development Index (HDI) (UNDP)

In the 1990s, the UNDP under the leadership of Mahbub-ul-Haq and Amartya Sen redefined the concept of human development as a development that enlarges choices. Development choices not only need to exist but should also be Accessible, Affordable. and there should be Real choices.

Development was measured under three parameters

  1. Income - Per capita GDP in PPP terms (II)
  2. Health - Life Expectancy at birth (HI)
  3. Education - Education index in terms of adult and child literacy rate (Enrolment ratio) (EI)
Human Development Index (HDI)Physical Quality of Life Index (PQLI)
Un-Weighted Arithmetic mean
(II + HI + EI) / 3
Weighted Mean
Different Weightages for different indices
HDI vs PQLI

In 2010 HDI, there have been modification in this indices.

2010 HDI modifications

  1. the income index is now measured in terms of per capita gross national income. Gionee is more comprehensive in terms of economic resources available for a country's development. It includes remittances and also exports.
  2. education index is now measured in terms of mean years of schooling of adult population and expected years of schooling for child population.
  3. health index continued to be life expectancy at birth and HDI is the geometric mean of the indices

Human development index = โˆ›(II + HI + EI)

The geometric mean exaggerates and amplifies the difference in achievements that are in the development lag.

Apart from HDI which primarily reflects the achievements of society, HDR-2010 also added three other induces to capture inequalities

  • Multidimensional poverty index
  • Inequality-adjusted Human development index
  • Gender inequality index

Multidimensional poverty index (MDPI)

Conventional HDI is measured only in terms of income. There are other dimensions of poverty such as food security, affordable housing, portable drinking water, affordable power, etc. According to 2014 HDI, greater than 50% of India's population have moderate multidimensional poverty and about 30% have severe multidimensional poverty.

Inequality adjusted Human development index.

It accommodates the inequality based under achievements and readjusts the HDI so that the new index captures both the achievements and the inequalities

Gender inequality index.

It captures the gender gap concerning life expectancy disparity, labour force participation disparity, political participation disparity.

Patterns of global Human development index.

HDI captures the development parameters of different countries and it categorises HDI into five categories.

5 Categories of HDI.

  1. Very high HDI
  2. High HDI
  3. Medium HDI
  4. Low HDI
  5. Very low HDI.

Patterns of HDI are

India has consistently maintained its position in the Mid and medium HDI. In 2019 India's rank was 129 out of 189 countries. In 2018 India's rank was 130 out of 189 countries. 

Very high HDI countries are Scandinavia, middle east, Kuwait, Qatar, UAE. The disproportionately high-income parameters more than compensate for the lower achievements in the social sector.

Very high HDI also includes Japan, Singapore, Chile, Argentina, Erstwhile USSR Estonia, Lithuania.

Almost all countries of the world I have consistently improved their HDI and this also is true for the sub-Saharan countries.

There is a large gap between and low HDI countries. Example on the income front, achievement off HDI countries is at least 20 times more than the low HDI countries.

There is a clear North-South divide in the development achievements. The north-south divide is based on Brandt line. The north comprises of more developed countries of America and Europe including Australia. The southern countries include Latin America, Africa, and Central and South Asia

Even among high and very high HDI countries, there is inequality within. There are social differences within a community inside the United States and the southern United States are lagging behind the more developed North-Eastern states. In Canada, the colder north and the agricultural regions of the west have lesser HDI compared to those on east like Quebec and the industrial regions along the Saint Lawrence River.

High HDI countries include Mexico, Panama, Libya, Uruguay, Algeria, Tunisia, Brazil, Ukraine, Bosnia, Iran, Lebanon. But these countries are no match to countries like Norway Sweden Denmark and other oecd countries.

Russia is one countries in high hdi that has suffered losses since 1990 due to its economic and social restructuring.

The intra country variation and ethnic disparities are the common aspect of almost all countries.

United States is among the top five HDI. But the HDI of Afro-Americans is 0.47 while the average HDI of the country is consistently greater than 0.9. The same is also for Brazil where average is greater than 0.7 but HDI for less developed state like amazonia, Pernambuco is 0.5.

Asia as a continent has the widest range of HDI. Countries like Israel and Singapore has greater than 0.9 HDI where as countries like Laos, Cambodia, East Timor, and Afghanistan have very low and low HDI.

Most of the very low HDI are African countries including the sub-Saharan Africa. Droughts and conflicts have aggravated historical poverty in Africa.

Social Well-Being

January 2, 2021 by Bhushan Leave a Comment Last Updated January 2, 2021

Development and Social Well-Being

Development is a subjective concept. Its scope can be defined in many ways. Different countries choose to define their developmental achievements according to their levels of development.

Development is also a dynamic concept. It changes with time. The HDR report defines development as a process of enlarging choices across economic, social, and political issues.

But HDI doesn't capture all the aspects of social and political achievements such as political freedom, rights against unlawful detention, social participation, perception about technology, and the ability to adapt and adopt the technology.

The HDR report acknowledges the importance of all-round development. It also accepts that quantifying and developing an index to capture all aspects of development is not easy. Hence the concept of social well-being.

Social well-being is a broad expression to capture all aspects of achievement and self-worth of individuals. Social well being can be explained in three dimensions.

The three dimensions of Social Well-Being

  1. Domain of Being
  2. Domain of Becoming
  3. Domain of Belonging

Domain of Being

It is about what a person in terms of his physical state, his occupation, and his emotional state. The being domain is about what a person feels about himself and what he things how he is perceived by others. It includes his income education and socioeconomic status.

Domain of Becoming.

it is the aspirational component of what a man seeks to achieve. It is about as future his hope his ambitions and why he does what he does.

Domain of Belonging.

it is a relational component of development. It includes the feeling of being a worthy contributor to the contributor in society at all levels family neighborhood workspace and even at an international and national level. It is the feeling that one has the capacity by virtue of his relationship with others.

Human development is a very broad subjective concept and all the above concepts are valid concepts even though we may not have objective measures as of now to depict them and quantify them.

Social capital

Social capital is the relational component of development. It is much like the domain of belonging in social well being. It is increasingly acknowledged that relationship, interpersonal, and inter social interactions are crucial determinants in all aspects of human development. Social capital is the sum total of collaborations, corporations, and participations based on trust and reciprocity. It is a resource which is beyond conventional sense of resources. According to Black and Hughes, there are four types of capital.

Four types of capital

  1. Natural capital - natural resources
  2. Produced capital - products of human activity including culture
  3. Human capital
  4. Social capital

Human capital

total of human labour skills knowledge and talent which is important to convert natural resources into produced capital

Social capital

relationship collaboration teamwork trust without which other capitals cannot be used or its benefits sustained. It is one of the prerequisites in achieving developmental goals.

The concept of social capital was first given by Pierre Bourdieu, a French cultural theorist who was trying to explain the process of social dominance and subordination in French society.

The modern concept was given by American social theorist Robert Putman who was trying to understand how social hierarchy develops in American society. His ideas were in the book 'making democracy work' and his concept was acknowledged by the World Bank.

Social capital operates in three ways.

  1. Bonding
  2. Bridging
  3. Linking

Bonding

The interrelationship and sense of belonging within a group which is similar in terms of population. Relationship and association between members who have similarities and the group which is relatively a homogeneous group. It is the earliest form of relationship.

Bridging

Collaboration and association between individuals and groups that are dissimilar for whom may seem perceptively opposed to another. Bridging is the most difficult component of interrelationship and lack of bridging is the basis of racism, communal violence, and cultural conflicts. Most countries and India in particular are yet to invest and use their official machinery to promote bridging. The role of media and government institutions play an important role in making it happen.

Linking

Linking is a relationship developing across different hierarchical groups.

Example

  • senior management and workers.
  • Bureaucracy and masses.
  • Upper caste and lower caste.
  • Higher class and lower class.

Social capital can be initiated, fostered, and strengthened by an interplay of trust, reciprocity, and mutuality.

social capital - Social Well-Being
social capital
  • Trust- faith
  • Reciprocity - the feeling that a good deed will result in a positive response.
  • Mutuality - A sense of interdependence and respecting the efforts of all groups that make up the team.

Social capital as a virtue can't be the automatic outcome and the natural consequence of economic and social achievement. It needs to be deliberately fostered. Social capital on the other hand can automatically guarantee economic and social development.

3. Regional synthesis

Regional synthesis as 'disruptive of the earth's unity' โž— and also 'Integrated' โœŠโœŠ??

One of the allegations against the regional approach was that while focusing on the 1specifics, the 2particulars, the 3uniqueness of the phenomenon, and the 4uniqueness of the place, the Regional Geography was 'Disruptive of the earth's unity' โž—. On the other hand in its 1 topical integration, the 2 systematic approaches with its 3generalizations and laws, it was more 'Integrated' โœŠ .

Regional approach as a 'better paradigm/approach in unification' โœŠโœŠ

These allegations against the regional approach were disputed. The regional approach is a 'better paradigm/approach in unification' โœŠโœŠ became the theme of regional synthesis.

Ferdinand Richthofen and organic unity of nature

It was Ferdinand Richthofen who was a Chorologist who tried to revive geography in the regional paradigm but he is not considered as a radical Chorologist because Richthofen's ambition was to revise geography in the concept of organic unity of nature much in the line of humboldt and Ritter's tradition. He too believe in the concept of Zusammen Hang hanging together.

He believed that the purpose of geography as regional geography has to be descriptive but the description cannot be the end purpose. The geographers must go beyond and seek regularities and similarities and establish the causal interrelationship within diverse elements that make up the region.

So, geography as a science of different kinds of things that exist together and are bound together by causal connection. This interconnectedness according Richthofen as a focus of study is possible only in regional approach of geography. Hence the concept of regional synthesis. This idea of Richthofen influenced all regional and Chorological geographers thereafter.

Hettner

Hettner for example is a radical chorologist and he criticized the geography as a science of earth's surface. Hettner nevertheless believed in the Causal interdependence Zusammen Hang and more importantly believed in dichotomy of human versus physical geography as irrelevant and wrong.

Ratzel, Vidal, and Hartshorn

Ratzel in his concept of Environmental Determinism, Vidal in his concept of Cultural regions (Payz) and Hartshorn in aerial differentiation all believed in integration and causal relationship to link man ๐Ÿ‘จ and environment in the regional perspective.

3. Morphology of Indian cities

December 5, 2020 by Bhushan Leave a Comment Last Updated December 6, 2020

Cities in India have a long history of evolution. So, the Morphology of Indian cities reflects its development during different historical phases.

In reality, no city would perfectly obey any of the generalized models like The Concentric Zonation Model, Hoyt's sectoral model (1939), or the Multiple Nuclei Model (1945).

Mostly all cities are partly spontaneous where history has played a more important role and are partly planned because of deliberate government policies.

American cities are much younger and therefore Central business district has exclusively commercial function, high risers, and skyscrapers.

But the Indian and European Central business districts are older. The cities will have a traditional architecture of not more than 2 or 3 stories. They will not have an exclusive commercial function. Such a Central business district will have a commercial function on the ground floor and first floor while the upper stories will have residential dwellings.

Since Indian and European cities are much older and have a long history, the region around the Central business district is always crowded with narrow by-lanes and a lack of civic amenities. Under the colonial experience, the New Central business district which is more planned was developed.

Almost all traditional cities of India have a lot of influence of different cultural architecture.

  1. The oldest cities with ancient origins have typical temple architecture. Temple towns of South India i.e. Madurai, Rameshwaram, Kanchipuram, Varanasi, etc.
  2. In medieval times with the advent of Muslim rulers, there was the influence of Islamic architecture (Persian influence). Indo-Saracenic style architecture with domes, minerals, gardens with waterfalls, Char Bagh pattern, etc.
  3. The European architecture is found in the presidencies and in the important administrative towns across India. The English brought with them railway colonies, civil lines, cantonments along with wider paved roads and better landscaping.

Social segregation is almost a feature of every city.

In European and American cities, the traditional segregation was on income lines. In India, segregation is based on racial and caste lines. Almost all cities of India have migrants from different regions and hence the cities also have linguistics segregations.

There are two models which can depict some of the features / Morphology of Indian cities

  1. The Bazaar Model
  2. The Port Based Model

The Bazaar Model

The planned extension will have its own European CBD and there is racial segregation.

The Port Based Model.

Many cities like Kolkata, Chennai, Madras, Pondicherry developed around the ports. The ports were once factories. Eventually, the ports were fortified and served both military and commercial functions.

The Port Based Model - Morphology of Indian cities

For Example, the city of Calcutta developed around Calcutta port. It has the fort, Fort William which initially was a factory and eventually armed. The European town is distinctly apart from the native town. The native town is a neglected unplanned region with old Bazaars and lacks amenities. The European towns and its planned extension have both racial and income class segregations.

The structure of planned cities in India

Almost all planned extensions in India were done during

  • Medieval times with Islamic architecture
  • British times with European architecture and better amenities
  • Post-independence modern planning which is invariably sectoral model (Iron grid model) Example - Chandigarh, Noida, Salt lake city, Navi Mumbai.

The sectoral model has a very efficient utilization of space in terms of connectivity with roads Crisscrossing at right angles.

Each sector is planned as a relatively self-contained sector with a shopping complex, schools, health services, etc.

Sectoral planning with mixed land uses tries to concentrate population so as to avoid the need for commuting over long distances for basic amenities.

Planning requires more clustering and encouraging vertical growth to deal with the congestion problem in the cities.
