Introduction

7/25/2019 Defense 2

PROBLEM DEFINITION

Although located in strategic

and key economic locations,

many informal areas show signs

of social pathologies and slum

like conditions. The people

living in these informal areashave poor socio-economic

conditions and did not get a

significant benefit from their

vital locations on the long run.

Cairo’s Deprivation index (according to

UNDP, 2008).

This indicator was built as follows (UNDP Egypt, 2005;

2008; UNDP, 2010):

DI = [1/5 (P13 + P23 + P33 + P43 + P53) ]1/3

Where:

P1 = Probability at birth of no surviving to age 60

P2 = Adults lacking functional literacy skills

P3 = Rate of long-term unemployment

P4 = Population below income poverty lineP5 = Gap in living standards

Questions

One key question that has no simple answer is examined:

• What is the relationship between the socio-economic segregation of a settlement and

its overall spatial Configuration?

And sub questions are:

•What are the forces that influenced the spatial development of Cairo through history?And to what extent such forces contribute to Cairo’s spatial division?

• To what extent are deprived areas spatially integrated at a neighborhood as well as city

level?

• Is the distribution and rates of commercial activities within informal settlements

mainly driven by the spatial composition of the area itself? Or is it more related to the

overall structure of the city?

• To what extent do the locals assimilate into their neighborhood and the city as a

whole?

Socio-economic Profile Abu Qatada

The greatest proportion of respondents is immigrants from

Upper Egypt and Delta governorates. However, most of

them were born in Cairo.

Illiteracy and unemployment rate s are relatively high.

The majority of inhabitants are self-employed in informal

sector of economy.

Their workplaces either in the ground floors of their

dwellings or at a walkable distance from there.

7/25/2019 Defense 2

Social Ties and sense of community

When asked about the social class of their external close friends, the majority of

respondents indicated that they belong to the same social class. On the other

hand, new residents and educated people showed less assimilation with the

hosting communities and stated that they have more external relations than

internal.

The spatially segregated disadvantaged areas were also socially excluded in

terms of social network and socio-economic profile.

7/25/2019 Defense 2

Social Ties and sense of community

• Variables of gender, origin, length of residency and ownership are noticed to

influence number of acquaintances, feeling of safety and sense of community.

• Males are more likely to know more people and to have higher feeling of safety

than females.

• Owners and long duration residents have stronger internal social ties and more

numbers of acquaintances than new law tenants and new dwellers.

• Education correlated positively with the inhabitants'' wish to leave. This means

that there will be a lack in more skilled people upon the time.

07.1 Review of Principal Findings

7/25/2019 Defense 2

Review of Principal Findings

• Random urban development has disrupted the overall continuity of the urban form. It

has absorbed core villages and suburbs and treated different parts of the city asisolated objects.

• Pushing poor people to the periphery has brought about a mushrooming of vacant

and underused lands in the urban core.

• Analyzing the spatial accessibility of Cairo shows that many informal areas are wholly

divorced from their wider urban context.

• Physical segregation denies people their basic right to the city, but it also starves the

city of its lifeblood and tears apart its social fabric.

7/25/2019 Defense 2

Review of Principal Findings

• Urban areas, as they grow, develop two types of structure: an internal – or

local – structure, which facilitates the local functioning of the area; and an

external – or global ‐ structure, which enables them to interact productively

and efficiently with the rest of the city (Hillier, 1996, pp. 343–4).

• The findings of this thesis contribute to support the theory of the naturalmovement economic process.

Realms of Contribution

Methodological Aspects

The building of an approach to study the relationship between space and socio-

economic processes in informal areas in Cairo is important contribution. At city scale,

it unifies various insights and methodologies from sociological, economic, geographic

and urban planning theories and approach into a holistic approach for better

understanding of mutual relations between space and society.

At a settlement scale, the research endeavored to link insights from urban and

economic perspectives.

Normalizing the commercial rate in the settlements, through using banding method, as

well as employing the ‘Gini Coefficientʼ provide reliable tools for investigating the

relationship between spatial parameters and land use distribution.

7/25/2019 Defense 2

Realms of Contribution

Policy Aspects

• Location of informal settlements should be connected to movement thoroughfares.

• Sub-centers of informal areas should be linked with each other within the wider urban

context in order to not only transport income from formal areas but also to restore

urban livability of the metropolitan.

• Urban land use should generally be planned on the basis of spatial accessibility that

minimizes time consuming travels and maximizes economic gain and socialinteractions.

• Identifying physical barriers and gaps should be seen as a first step in the process of

urban restructuring. Those not local to an area will surely be encouraged to use it more

were these barriers to be removed. Improving connectivity in this way is likely to

generate new movement patterns that will draw in new economies, stimulate

investment and so stimulate the “virtuous cycle” of regeneration.

• Integrating configurative approach and, social and economic thinking into master

planning and design decisions will facilitate creating the right balance between

physical and social systems and this in turn will enhance a better wellbeing and

quality of life.
