Deteriorated unplanned settlements/Slums a disturbing reality
• According to UN-Habitat’s ground breaking report, The
Challenge of Slums, in 2003, 924 million people, or 31.6 per cent
of the world’s urban population, lived in slums or squatter
settlements.
• The majority of these settlements were in the developing
regions, accounting for 43 per cent of the urban population (UNHABITAT, 2003).”
• These figures are unfortunately in continuous rise according to
internationally verified statistics (UN-HABITAT, 2006).
• Due to complexities of defining a slum area, these figures don’t
necessarily include the ‘slum-like’ conditions of many other
deteriorated urban areas, such as historic centres, which would
not automatically qualify as a slum.

Unplanned/informal settlements and slums
Not always is an informal settlement a slum, or is a slum created in
unplanned areas, but it is fair to say that in most cases slums happen to be
informal or unplanned areas that are suffering from multiple physical or
socio-economic problems.
Dr. Kayvan Karimi, Ed Parham
Regenerating urban slums a huge challenge
In many developing countries, the governments that don’t have the
resources, or are highly influenced by economic, social and political
agendas, resort to a variety of harsh solutions to transform the slums.
“urban segregation is not a frozen status quo, but rather a ceaseless
social war in which the state intervenes regularly in the name of
‘progress’, ‘beautification’, and even ‘social justice for the poor’ to redraw
spatial boundaries .. (Mike Davis, Planet of Slums).”
.
In other words, the whole effort is sometimes about eliminating the
question through removing human encumberments, urban evictions, city
beautification, slums de-criminalisation, and so on, rather than finding a
solution to create a condition that informal settlements could self-correct
themselves.

Slum Clearance The UK case
Much of this effort was
associated with slum
clearance, as encouraged by
the 1930 Act, which made
the local authorities
responsible for slum
clearance and providing
alternative accommodation.
Dr. Kayvan Karimi, Ed Parham
The social approach illusion of ‘self help’
At the other end of the regeneration spectrum, it is argued that the slums
have to be fixed by themselves. By helping people to help themselves, the
life conditions will improve and the slums will be saved.
Being much less costly, interruptive, and authority-dependent, this
approach is favoured by institutions such as the World Bank, international
aid agencies, NGOs and philanthropists.
On the face of it, it looks like a good approach, but when it comes to the
realities of the vast slums and deteriorated areas, the solutions do not seem
to work.
Mike Davis goes as far as calling it the ‘illusion of self-help’ and scholars
such as Jeremy Seabrook, call it a misrepresentation: “it would be foolish to
pass from the distortion – that the slums are places of crime, disease and
despair – to the opposite; that they can be safely left to look after
themselves (Seabrook, 1996, p. 197).”
So, what should be done?

Current conditions
Conditions across settlements vary but all of them combine at least
3 of the 5 characteristics the UN uses to define a slum:
• Inadequate access to safe water
• Inadequate access to sanitation and other infrastructure
• Poor structural quality of housing
• Overcrowding
• Residential status

Reversing the cycle of decline
How can an intervention be developed to address the fundamental spatial
problems at the heart of the unplanned settlement condition, and which can
respond to potential changes in the economic, social and political conditions?

Approach Spatial intervention
If the heart of the unplanned
settlement condition is spatial, how
can changes be made to spatial
structure which minimise disruption to
existing residents and stakeholders?
If each of these approaches has its own
strengths which are suited to a
particular set of economic, social and
political conditions, what can be done
to combine the benefits of all of them
and switch between them?

If the wider context to the project does not support the levels of
investment required to implement changes to reverse the cycle of
decline, what can be done to slow it, improve living conditions, and
start to create the forces of change?

Current problems
What improvements need to be made to improve existing
living conditions?
Poor access for vehicles (Cars, Security, Refuse)
No Street lighting
Poor access to Education facilities
Perception of crime
No Pavement
No Road Surface
No connections to Sewers
Streets blocked by cars and rubbish (no Parking)
Inadequate access to services
No access to Water mains
No Storm Water Drainage
No connections to Electricity
Poor condition and lack of maintenance of buildings
Poor access to Health facilities
Uncollected rubbish
Poor quality Public Spaces
Difficult to establish local Economic Activity
Dr. Kayvan Karimi, Ed Parham
Analysis and strategic design Principles of design
How can improvements be implemented?
Improvements cannot be implemented across
the whole settlement uniformly so a framework
for improvement is required.
Route-based improvement of Access, Utilities,
Public Realm and Face Lifting
Settlement-wide improvement of access to
services and Social Infrastructure
Self-organising regeneration through guidelines
and access to micro credit

Route-Based Improvements Face Lifting
In the immediate term “Face Lifting” can be carried out to
improve conditions quickly and cheaply.
This could involve re-painting facades, removing all
abandoned vehicles and cleaning up Public Spaces.

All Projects
Some elements of the framework are flexible enough
to be delivered early if the budget is available
If additional budget is available, some items can move
forward
If less budget is available, key improvements can be
chosen and the rest shifted back
