1 INTRODUCTION
1.1 Sustainable urban design – an introduction
The word “Sustainable design “has been used everywhere ranging from
environmental applications and building technology to transportation and social
factors. In urban design sustainability is a holistic mix of all these various aspects,
where each of these aspects are mutually interrelated and contribute on its own to
the sustainability of the entire area or district .
1.1.1 Sustainability – key factors
Sustainability, in a broad sense is the ability to maintain a certain process or
state1. Sustainability has become a complex term that can be applied to almost
every facet of life on Earth, particularly the many different levels of biological
organization, such as wetlands, prairies and forests and is expressed in human
organization concepts, such as eco-municipalities, sustainable cities, and human
activities and disciplines, such as sustainable agriculture, sustainable
architecture and renewable energy.
Sustainable development is said to be the development that consider social and
economic factors as well the environment in an integrated and a holistic way.
Sustainable development is essentially said to be a concept of resource
1 http://en.wikipedia.org/wiki/Sustainability

conservation and development. The important resources affected most by urban
design and development are land, particularly green areas, ecological systems
and bio-diversity, air, water, physical infrastructure, the built environment, human
health and well-being, social relations (‘social capital’) and cultural heritage.
‘Sustainability’ is mainly concerned with environmental issues and the long term
husbandry of natural resources, while ‘development’ has focused on balancing
longer term economic growth with achieving social equity in ‘meeting needs’
through the equitable distribution of economic and social goods and, in particular,
in overcoming poverty. Compared to indicators of economic and social aspects,
environmental and sustainable development indicators are a relatively new
phenomenon. The Rio Conference on Environment and Development in 1992,
and other similar environmental milestone activities and happenings, recognized
the need for better and more knowledge and information about environmental
conditions, trends, and impacts.
1.1.2 Urban design – key factors
Urban design is defined as, first, the physical design and planning of the built
environment (physical infrastructure, building complexes, spaces and urban
areas) in relation to the natural environment in and around built-up areas and,
- 10 -
second, the production of concepts and models that serve the purpose of guiding
the sustainable development of settlements. 2
The challenge for urban design is to respond to the emerging patterns of urban
growth, migration and environmental depletion in a proactive way that overcomes
negative effects such as excessive car-based mobility and urban sprawl.
Growing prosperity and wealth and increasing demands for an improved quality
of life are reflected in the increasing consumption of land and space, demand for
privacy and better living conditions and access to green space. Urban design can
help provide the physical framework for overcoming differences and segregating
processes, as well accommodating the need for a variety of expressions of
cultural and ethnic identity.
The overall aim of sustainable urban development is to achieve a healthy and
high quality of life for all people and subsequent generations, with equitable and
geographically balanced and socially cohesive economic development, which
reduces the impact on the global and local environments.
1.2 Developing city – a complex scenario
Developing countries are facing unprecedented challenges towards sustainable
societies in the sense that they have to balance economic growth and
2 Urban Design for Sustainability, Final Report of the Working Group, European union
- 11 -
environmental consideration even though they are not major contributors to
environmental loads. Different from the situations at early development stage of
developed countries, developing countries have to pay more and more attentions
to such accessibility space in order to realize the same level of economic growth.
Urbanization is one of the most powerful forces influencing global sustainability. It
is dominated by three factors: population growth, rural-urban migration and
subsequent urban expansion. Perhaps nowhere are these factors more dominant
than in developing countries and this point to a challenging scenario of having to
look into these widely contradicting phenomenons with equal importance.
1.3 Calicut – a developing city
Calicut (Kozhikode) is a city in the state of Kerala, southern most tip of India.
Calicut is a coastal city with an urban population of 0.8 million with a decadal
growth of 9.67 % and an urban population density of 1000 p/sq.km, while state
avg.urban population density is 700 p/sq.km. The temperature within city limits
varies between 23 oC – 36 0 C.
- 12 -
Fig:01 Location of Calicut city
Calicut is the erstwhile capital of powerful Zamorins and is a historical town with
a hoary past. The charming physical features and prosperity of the town attracted
travelers from all over the world. Being a major trade centre with abundant supply
of spices Calicut turned out to be a very important economic base for British in
south India. The development of Calicut in the post independence period (1947-
2009) is considered as stagnant with respect to its glorious past. At present
Calicut is a prominent city in the southern peninsula of India with a high potential
of growth and development.
1.4 Objectives and Scopes
This study aims at understanding and evaluating various sustainable urban
development potentials in a developing city with focus on city of Calicut, India.
The scope of the study is limited to the parameters of sustainable development
that are found to be important in the case of Calicut and similar type of cities.
- 13 -
1.5 Research Methodology
The study starts with a set of research questions aiming at redefining sustainable
urban design to the context of Calicut based on the understanding of the author.
• What does “sustainable urban design “mean in different contexts?
• What are the different perspectives of sustainable urban design in
developing and developed cities ?
• sustainable development – formal and informal dimensions in a
developing city
• sustainable development – local and global perspectives
• sustainable development in developing cities – a time-space phenomenon

2 LITERATURE REVIEW
2.1 Various concepts of sustainable development
The key aspects of Economy, Environment and Society are considered as the
three pillars of sustainable development. This view was predominant at the Earth
Summit or UN conference on Environment and Development in Rio de Janeiro in
1992. One of the main outcomes of Rio was Agenda 21, intended to provide a
basis for achieving sustainable development in the 21st century. The tendency
has been to view ‘sustainable development’ as a unitary concept that
incorporates environmental, social and economic components. Other
‘dimensions’ of sustainability are also discussed by various experts such as
‘institutional’, ‘cultural’ or ‘physical’.
Fig:02 The three pole concept of sustainable development
- 15 -
The ‘three-pole’ concept of sustainable development is the one that underlies the
Habitat Agenda – the outcome of the Habitat II Conference or ‘Cities Summit’ in
Istanbul in 1996.
Fig:03 The three pole concept of sustainable development: a different outlook
Sustainable development and urban design are indeed closely linked (C.
Mougthin, 2005). Some current concerns in urban design, such as the form of
urban space (gestalt), vitality and identity of urban areas, quality of urbanity,
respect for tradition and the preferences for developments of human scale, can
all be encompassed within the scheme of sustainable development.3
In order to have a deeper understanding on sustainability, it is worthwhile to refer
the general definition, theoretical framework, of sustainable development, which
is taken from the Burndlandt Report “Sustainable Development is development
3 A study on city of Bandung
- 16 -
that needs of the present generation without compromising the ability of future
generations to meet their own needs” (World Commission on Environment and
Development, 1987).
Firstly, in course of the term of development, according to Blowers (1993), it
should not be confused with growth. Growth is a physical or quantitative
expansion of the economic system, while development is a qualitative concept. It
is concerned with cultural, social and economic progress. Secondly, the term
needs introduces the ideas of distribution of resources: “meeting the basic needs
of all and extending to all the opportunity to satisfy their aspirations for better life”
(World Commission on Environment and Development, 1987). There is one
argument concerning the term needs, meeting needs is therefore political, moral
and ethical issue, since the meaning of needs for everyone will not the same.
Other important principles of sustainable development are offered by Elkin (1991)
as follows: futurity, environment, equity and participation. The first principle
futurity is seen as maintaining a minimum of environmental capital including the
planet’s foremost environmental support systems, together with the conservation
of more conventional renewable resources. In terms of Brundlandt’s
requirements, this means that human activity should allow for its effect that may
have on the ability of future generations to meet their needs and aspirations. The
second principle environment is based on the argument that sustainability
constraints are difficult to define with any precision. It is possible, however, to
- 17 -
identify the direction of changes in consumption patterns that are necessary to
avoid breaching environmental threshold. By applying this principle, it should be
possible to outline the type of development that is more sustainable. The last two
principles equity and participation support the first two main principles of
sustainable development. At a time where increasing issues of democratization
in planning process participation has nowadays become a common feature of
development procedures, with groups of ‘stakeholder’ involved in consultations.
The environmental or ecological dimensions to urban and regional design
emerged steadily through the 1980s. In the following years the proliferation of
writing on concepts of sustainable development has shifted the urban design
agenda towards broader environmental concerns. Of greatest significance in
sustainability terms were the problems of depletion of scarce natural resources,
escalating pollution and the destruction of biodiversity. Thus, urban design will
play a role as a tool in designing our environment.
2.2 Parameters of sustainable urban design
According to J. Punter/M. Carmona, (1997, pp. 79-81) recent research has
focused sustainability concerns upon the environmental stock in terms of three
main aspects.
• Global ecology
- 18 -
o air quality, climate, biodiversity, water, land, mineral and energy
resources
• Regional resources
o Air, Water, land, mineral and energy resources
• The human environment
o Buildings, infrastructure, open space, aesthetic, cultural and built
heritage.
Sustainable urban design is also described as the sustainability in the physical
aspects of an urban environment (Randall Thomas, Max Fordham, 2003). The
physical aspects in this description are listed as
• The buildings and their engineering systems
• Green and open spaces
• Transport systems
• Energy
• Water and waste systems
In the report submitted by the working group for studying urban design for
sustainability in European union it is suggested that urban design for sustainable
development should address the following objectives
• The protection of the natural environment and conservation of natural
resources at the local and regional scale;
- 19 -
• The reduction of the impact on the natural environment at the global scale
and in the longer term: reducing ecological footprints and achieving
balanced production and consumption systems;
• Promoting balanced and appropriate economic development whilst
reducing social inequalities and improving social integration and cohesion;
it is particularly critical to address directly the social issues and rapid
changes arising out of mass immigration from low income countries.
• Advancing the quality of life in relation to the above
• Promoting the long term health of the citizens, including addressing the
relationship between social and psychological well-being and the
possibility of experiencing elements of nature locally (particularly important
for children).
- 20 -
3 FORMULATION OF AN INDEPENDENT UNDERSTANDING
3.1 Sustainability in urban design
Sustainable development focuses on the qualitative aspects of economic
development, for example, in organizing production and consumption processes
in a more cyclic, balanced way, and choosing forms of production that minimize
the use of resources and environmental pollution. Similarly, urban design for
sustainability is not against economic development, but supports the
concept of combining economic development with environmental progress.
The physical design of infrastructure and the built environment, and the way the
land is used and developed, noting that the value of land as agriculture area is
generally much less than if it is planned for development, is clearly of key
importance to balancing production and consumption patterns and achieving
sustainability.
In this respect the concept of the ‘ecological footprint’ is helpful. There has been
a tendency to use this concept in relation to individual cities, in the negative
sense that cities have been viewed as more unsustainable than rural areas, but
also in the positive sense that self-governing cities can be strong management
units that can take positive steps at the local level, particularly through Local
Agenda 21s, to improve their contribution to sustainable development.
- 21 -
The 1990 Commission Green Paper on the Urban Environment focused on
• car-based suburban sprawl
• congestion
• pollution and
• segregated land uses
as the key problems that sustainable urban design should address.
Sustainable urban design is a process whereby all the actors involved (national,
regional and local authorities, citizens, civil society and community-based
organisations, research, academic and professional institutions and the private
sector) work together through partnerships and effective participatory processes
to integrate functional, environmental, and quality considerations to design, plan
and manage a built environment that:
• Creates beautiful, distinctive, secure, healthy and high quality places
for people to live andwork in that foster a strong sense of community
pride, social equity, cohesion, integration and identity at the local and
wider scale.
• Supports a vibrant, balanced, inclusive and equitable economy and
promotes effective urban regeneration.
• Treats land as a precious resource that must be used in the most
efficient way possible, reusing land and empty property within the
urban area in preference to seeking new land outside and avoiding
- 22 -
urban sprawl: compactness of the city at a human scale as a local
development requirement; concentrated decentralisation as a regional
development pattern.
• Looks at cities and smaller settlements in relationship to their
hinterland and to one another, considers the functional existence of
city regions, networks and urban corridors and systems and their
development trajectory, and treats the urban and rural landscape of the
city region as an integrated whole.
• Ensures the strategic location of new developments and local area
development in relation to the natural environment (addressing
resource conservation, biodiversity and public Regeneration
• Promotes mixed land use to make best use of the benefits of proximity
(easy and equitable access to services, amenities, green areas and
workplaces), ensure the maximum efficiency in the use of public
infrastructure and services, a balanced community and population
structure, vitality and security in the use of public space and
adaptability in the long-term development of built space (with the
concept of adaptability applied to existing and new buildings alike).
• Has sufficient density and intensity of activity and use so that services
such as public transport are viable and efficient whilst achieving a high
quality living environment (including appropriate standards of privacy,
personal space and minimising adverse effects such as noise and
pollution).
- 23 -
• Has a green structure to optimize the ecological quality of the urban
areas including microclimate and air pollution, and give access to a
biodiversity for those who lives in the urban areas to explore,
experience, learn about nature elements.
• Has high quality and well-planned public infrastructure including public
transport services, pedestrian and cycle networks and networks of
streets and public spaces to promote accessibility particularly for
disadvantage communities and to support a high level of social,
cultural and economic activity.
• Makes use of the state of the art of resource saving technology
including low energy
• housing and other buildings, environmental technology, fuel efficient,
non-polluting transportations systems, recycling systems, district
heating and bio-mass fuelled and other alternative forms of power
production.
• Respects and builds upon the existing cultural heritage and social
capital and networks of existing communities whilst avoiding
conservation for its own sake.
3.2 Sustainable parameters in a developing city
As discussed earlier, developing countries and cities face the greatest challenge of
balancing the rapid urban growth and the aspect of long term sustainability within
- 24 -
the economic, social and political limitations they possess. This complex scenario
demands a new way of thinking for the development of these third world cities for
their local sustainability and in turn for the global sustainability. There is a need to
combat the basic issues as poverty, unemployment, social segregation, loss of
governance before there is a discussion about the other factors of sustainability.
The level of pollution of air and water, the loss of bio diversity through the rapid
urbanization and urban sprawl and the loss of green spaces are also not to be
neglected, though these factors always take a second stage when compared to the
basic needs of a society toiling hard for their existence.
Each city or region will have its own natural, social and economic capital which has
developed in the course of the history. It is important that these assets are
conserved, developed and transferred to the coming generation to uphold the
concept of sustainability as discussed in the above chapters. Identifying of the key
assets in these three aspects can thus play the key role in sustainable urban
design of a developing city. The sustainability in a developing country has to be
seen as a time-space phenomenon which depends largely on the period of
discussion and also the context of the discussion. It is very important that both
local and global perspectives of sustainability are considered and discussed at
these various levels for a consistent and true analysis and design. These points to
a complex scenario which makes it difficult to generalize sustainability for
developing cities as a whole as the aspects are too contextual and periodically
variable.
- 25 -
3.3 Sustainable urban design – an independent perspective
As seen from various studies, Sustainable urban design has different parameters
and the relative importance of each parameter differ from cities and locations. The
study attempts to find out the relative importance of these various parameters in
the case of a developing city, specifically for Calicut.
Any discussion on sustainable development of a developing city has to consider all
three aspects of natural, economic and social capital. The study essentially looks
at how urban design as a tool can be used to conserve, develop, enrich and
transfer these assets to future generations as well.
A developing city, fights with various contradicting forces regularly for its existence.
Poverty, unemployment, migration, urban sprawl, environmental degradation etc
are some factors which are common to all developing cities and fighting these is
the one of the basic necessity of urban design. But urban design and planning
cannot just concentrate on the mitigations of the problems that the city face in a
specific period, but also have to look into the future, considering the morphological
development of the city, its strengths and weaknesses. Thus sustainable urban
design also has to consider various potentials of the city to realize the vision of
being a developed city in future. These highly contradicting forces of mitigations
and development will lead to several conflicts and urban design in turn has to
- 26 -
consider these conflicts and set out guidelines on how to overcome these conflicts.
Being a developing city means the planning process will have a number of
limitations like fund availability, political stability, social stability etc depending on
the specific situations. It is thus very important that a sustainable urban design
process look into all the limitations and consider them as a major factor so as to
make the resultant plan sustainable and realistic.
Thus Sustainable urban design has four major roles in a developing city.
• To meet the necessity of the people and the environment
• To cultivate the potentials for future growth and development
• To overcome the conflict of balancing immediate and future needs
• To realise all limitations and to convert them into strengths
For urban design to be sustainable in a developing city and to be sensitive to the
sustainability of the city as a whole, it has to look into all the various parameters
and perform the different roles efficiently, so as to balance all forces. These
aspects have to be applied through physical parameters like built environment,
infrastructure layout, land use mapping, green networks, waste disposals etc.
- 27 -
4 ANALYSIS AND EVALUATION OF CASE STUDY
4.1 Calicut – present status
The major strength of Calicut as a city are its
• hospitality
• the historical background
• the traditional trade sector
• the urban wetlands
• the fact that it is well connected by air, sea, road and rail
• the presence of leading public and social institutions and
• proximity to other key cities.
The major weaknesses are
• lack of proper planning
• virtually dead sea- port
• no anchor economy
• inland water ways whose potential is not yet realized
• lack of infrastructure causing hindrance for growth
• lack of coordinated sustainable development and
• lack of concept and master plans.
The city though boasts of a unique 240 acre urban wetland and various green
open spaces within the corporation limit, it has no development plan integrating
- 28 -
these along with the total urban design scheme. In fact a look into the recent
developments will reveal that the developments proposed in these highly
sensitive green lungs of the city are highly non-sustainable. This scenario calls
for a total analysis of the development schemes in the city in a sustainable
development perspective.
Fig:04 Calicut – physical structure
- 29 -
4.2 Sustainable urban design parameters
4.2.1 Ecology
Ecology is one of the three corner stones of sustainability and holds a key
position in urban design aspects as well.
4.2.1.1 Necessity
Total availability of open space in Calicut is 14.94 hectares (0.038 hectare per
1000 persons) and it is just 9% of the minimum accepted standard of
(0.4 hectare per 1000 persons) .This suggests it is a necessity not just to look
into conservation of existing green areas but introduce more green zones by
integrating various small pockets of un utilized spaces through proper urban
design guidelines.
Calicut is blessed with various urban water channels consisting of rivers and
canals and most of them have turned to be mere waste drains due to lack of
proper planning. Even the urban wetlands have been reducing at rapid rates
causing a big threat to a wide variety of bio-diversity it supports. Conserving and
preserving these key ecological capital areas are there fore a necessity of urban
design plans.
- 30 -
4.2.1.2 Potentials
The presence of a 240 acre wetland within the city provides a unique oppurtnity
for a bio-diversity park and centre and community learning centres which will also
help to conserve and protect these highly valuable natural assets. Long coastal
lines are also an unrealized potential which can be further developed through
careful planning. Realizing these potentials in urban design plans can have wide
impact in the ecology and economy of the area.
Fig:05 Calicut – green spaces
- 31 -
4.2.1.3 Conflicts
The immense land value of the urban wetland zones and green zones are facing
a big threat to the idea of conserving and developing it as a green zone from
various real estate forces. As these real estate forces are the key to the
economical support of the city as a whole, the factors like this possess a conflict
in the land use plans and sustainable urban design has to adapt to these
conflicting situations to balance the requirements.
4.2.1.4 Limitations
Lack of strong leadership with strong environmental perspective and lack of
participation of all stake holders are main reasons for improper conservation of
green zones and urban wetlands. These limitations have to be overcome through
proper evaluation and participation in the urban design process which is also a
key aspect in the sustainability of the city.
4.2.2 Economy
The major economy generators are agriculture (coconut, paddy, banana, tubers,
and spices), fisheries, and trade (industries – tiles, wood, and food products
- 32 -
Economy), tourism, medical tourism, wetland and cultural tourism, port and ship
building, institutions and consumerism and Middle East NRI income .The major
issues are lack of an anchor economy, capitalizing critical strengths, and the
political system. The proposals are special economic zones, industrial townships,
it parks.
4.2.2.1 Necessity
Calicut, though had a number of industrial units based on clay tile production,
food processing, cottage industries and spices marketing, many of these
industries have disappeared due to lack of designated zones, support facilities
and infrastructure. The traditional trade zones are giving way to real estate units
resulting in the decrease of Calicut’s importance as a trade city. For the
sustainability of the city it is important that urban design plans look into these
aspects as a basic necessity and designate definite zones of industrial
development and trade with strict controls and good infrastructure support.
4.2.2.2 Potentials
The presence of many leading technical educations and an international airport
within the city provides an opportunity to look into new aspects of economical
development like IT and Software parks and Hi-tech Business units. These can
be incorporated in the urban design plans looking it as a sustainable potential
- 33 -
along with other parameters. Traditional industries can be revived by providing
them with basic needs and support. Tourism is yet another major potential which
has to be integrated to urban design schemes.
Fig:06 A resort in Calicut
4.2.2.3 Conflicts
The lack of proper planning in last few decades has resulted in haphazard
development of an intense mixed use typology which now possesses a threat to
proper designation of industrial and business zones. There has to be strict
controls within urban design plans for the proper sustainable growth of these
aspects.
- 34 -
4.2.2.4 Limitations
The availability of designated land and increasing public protests against
undertaking of land are the biggest limitations in getting a development proposal
successful. This can be countered through strict urban design plans
encompassing all requirements and demands.
4.2.3 Equity
Calicut boasts of a highly historically developed culture with a religious mix of
hindhus, muslims and Christians and is known for hospitality, education and
trade. Major potentials are community initiatives like kudumbashree and social
and public organizations .The major issue are lack of integrated involvement in
development, lack of involvement in planning and decision making, rising number
of extremists and unemployment and Middle East returns. The major proposals
are local community initiatives, empowering common people through information
and environmental initiatives like CSDI.
- 35 -
Fig:07 kudumbasree – a social initiative
The major issues in waste disposal are unplanned city drains, lack of integrated
sewage lines, blocked storm water drains, untreated sewage to canals, lack of
sewage system for many areas and lack of treatment plants. One of the major
sustainable initiatives is Kudumbashree units taking care of waste disposal under
community initiatves. Quantity of waste generated from the urban area is 350-
500 tonnes per day and out of that only 50% of the wastes generated are
collected for disposal. Around 200 tonnes of waste is left to decompose on road
margins, drains, canals, water bodies and open space.
The reason for poor waste management is the absence of segregation and
primary collection from the source of its origin. Kudumbashree – the state
poverty eradication mission, in its 'clean kerala business' do a door to door
- 36 -
household waste collection and transport to the transit points fixed by the urban
local bodies. It is a a means of livelihood to the urban poor especially women.
(Rs 3,000 to Rs 5,000 per month) and also provides employment for 18,500
women all over the state
Fig:08 community waste disposal initiatives
4.2.3.1 Necessity
Many of the traditional public space have given way for real estate developments
and passive green areas which is one of the main reasons of lack of social
interaction leading to development of extremist activities. It is important for a
multi racial and multi religious city like Calicut to have good and effective public
spaces for interaction and recreation. The conservation of development of such
public spaces have to be a considered as a necessity in urban design plans.
- 37 -
4.2.3.2 Potentials
Presence of leading social and educational institutions, proximity to other key
cities and areas of raw material availability, availability of developable land and
the presence of a well connected infrastructure provide Calicut with a good
potential of growth which is not yet realized. Through careful and sustainable
urban design plans these aspects can be given a much needed boost to develop
to its potentials.
4.2.3.3 Conflicts
Many social activities like community participation in solid waste management
and collection, women empowerment through house hold industries etc have
created a chance for a better societal integration and development. But these
also act as a conflict when not properly addressed in land use plans as these
community programs are devoid of any designated place for waste disposal and
collection resulting in its inefficiency and also contamination of unwanted areas.

4.2.3.4 Limitations
A major limitation in the effective development and conservation of public spaces
are the unavailability of funds to maintain these facilities. Lack of maintenance
lead to the increase of crime activities and illegal activities in such public spaces
and these spaces turn out to be a menace for the society. Proper incorporation of
these aspects and realization of actual capability on type of spaces that can be
developed in the urban design plans will lead to a better and sustainable
proposal.

5 CALICUT SUSTAINABLE DESIGN INITIATIVES
5.1 Canoly canal development scheme
Canoly canal development project is the development of a 11.2 km man made
canal which connects Elathur river in north and Kallai river in south .It was made
by British in 19th century for the transportation of goods .It plays a major role in
the urban form, means of living, transportation, bio-diversity, ecological balance,
rainwater drainage and socio-cultural activities .the study will look into the detail
of the project.

5.2 Sarovaram Bio-Park
Sarovaram bio park project is a 273 acres wetland ecosystem bio-park
development with emphasis on conservation, restoration, recreation and
tourism. The importance of wetland ecosystem are
• It improves water quality due to natural processes
• It is home for numerous flora and fauna
• It is the drainage basin of the city
• It maintains city’s ecological balance
• It helps in species preservation and enhancing bio diversity
• It provides environmental learning opportunities
• It is very valuable as sources and sinks,
• It transformers of a multitude of chemical, biological and genetic materials
and
• It plays an important role in controlling pollution, flood and recharging
ground water aquifers.

6 CONCLUSIONS
The study has attempted to answer the research questions and also to find a
right approach of sustainable urban design for cities like Calicut.
The study has found out that sustainable development has different aspects to
be considered in developing cities like Calicut. All three main pillars of
sustainable planning, Ecology, Economy and Equity has to be overlooked
through these main aspects of necessity, potential, conflicts and limitations to
result in a sustainable proposal.
The study also has realized the importance of striking the balance of these
various aspects and key parameters of development and conservation. It has
found out that sustainable urban design is very subjective, both locally and
globally and changes with each location depending on local variables.
The aspect of time and period of discussion is also identified as a major factor in
developing countries as the forces are highly variable and has to be balanced
between the conflicting situations of necessity and development at all times.
Sustainability in urban design is highly depended on the level of integration of of
key aspects of socio-economic and environmental aspects.

The success of sustainable urban design in developing cities largely depends on
its capability to counter the conflicts and limitations in the form of corruption,
political forces, economical backwardness, lack of strong leadership, vested
interests and contradicting forces.
Specifically in Calicut, though there are some initiatives as the part of Calicut
sustainable development initiatives, the projects has its own potentials and
threats
Potentials
• Exploring the high potential of Calicut as a Green/sustainable city
• Bringing employment to the people
• Restoring the natural habitat the urban area
• Protecting the bio-diversity
• Enhancing the natural processes
Threats
• Over emphasis on aesthetics
• Over emphasis on tourism and secondary income
• Negligence of local community and community participation
• Lack of common interest
- 45 -
The main concerns that have to be overlooked in the sustainable urban design of
developing cities are
� lack of integrated planning and coordination between various agencies
resulting in haphazard development
� lack of vision plan and the ignorance about sustainability aspects
� lack of awareness among common public about the important of green
spaces and the current pollution rate
� eroding social and religious cohesion and unity
� lack of proper enforcement of rules and regulations regarding
construction, sewage and water treatment
� lack of strong leadership and authority leading to corruption and dilution of
laws and regulations resulting in the depletion of environment
