Recombinant urban DNA connectivity through adaptation in DiepslootNair, Simona 02 1900 (has links)
70% of the world’s population will be living in cities by 2050. Cities are
growing faster than can be designed. Townships and informal
settlements are becoming a common site within cities around the world.
South African cities are ill and require healing. It has inherited an intrinsic
genetic flaw, apartheid’s social and spatial planning. This urban DNA
structure encouraged weakness in the connectivity systems and was
designed to prevent people from connecting and contracting. It is Postapartheid
times and this weakness continues. Therefore the location of
interest is Diepsloot, a disconnected post apartheid township. Over 400
000 people reside in this township which is located between two major
cities in Gauteng.
The conceptual framework is based on the analogy of the Recombinant
DNA applied to how urban design unfolds. The scientifically engineered
process of healing through sharing, recombining, accepting and adapting
is a strong methodology to adopt into the urban design process and
methodology.
The theoretical framework looks at Peter Calthorpe’s New Urban
Network is based on reorganising transport networks into a hierarchy
which assists in increasing connectivity and improving the quality of the
urban network. While Complex Adaptive Systems theory is understood
through Sanders’ five complexity-based observations about cities and
urban environments. David Grahame Shane’s explanation of the theory
of recombinant urbanism involves the theory that cities emerge from
armatures, enclaves and heterotopias which are all constantly combined
and re-combined.
In addressing spatial inequalities and disconnectivity,
three bases of literature have been reviewed. The literature review
includes Compact City and Decentralised Concentration, New Urbanism
and Transit Oriented Development – Urban Network System. The work
researched and developed in these design movements and approaches
are vast. This study touches on the essence of the design movements and
approaches. The challenge is the application of these strong design
approaches or movements into a local context.
The hypothesis says that it is possible to develop a design methodology
that works from a parallel system of both bottom up and top down
design processes. It is possible to extract a strength in the current organic
structure of a township development, and incorporate it into formal
urbanism design tools. This is to ensure that the formal design
intervention is adopted into the current system, or study area, and
adapts and grows incrementally. Similar to the process of how the host
would accept the recombinant DNA of the antivirus.
The aim of the design intervention is to apply local lessons learnt in the
existing spatial context and link the strengths found with contemporary
urban design principles of transit oriented development that encourage
connectivity and intensity of development around intermodal facilities.
This approach demonstrates a design methodology that employs a
parallel system of bottom up and top down processes. The approach
developed is specifically, a design and a physical built morphology
analysis and does not include the arm of social interaction in the form of
public participation, etc.
The findings demonstrate that connectivity and density is a critical
component to healing the city. This discussion is held within the Transit
Oriented Development model. The study analysed the level of
connectivity Diepsloot exhibits from a regional scale, to a district scale
and finally to a neighbourhood scale. Healing the weakness of disconnectivity requires tackling it from all scales.

The SLEUTH urban growth model as forecasting and decision-making toolWatkiss, Brendon Miles 03 1900 (has links)
Thesis (MSc (Geography and Environmental Studies))--Stellenbosch University, 2008. / Accelerating urban growth places increasing pressure not only on the efficiency of infrastructure
and service provision, but also on the natural environment. City managers are delegated the task of
identifying problem areas that arise from this phenomenon and planning the strategies with which to
alleviate them. It is with this in mind that the research investigates the implementation of an urban
growth model, SLEUTH, as a support tool in the planning and decision making process. These
investigations are carried out on historical urban data for the region falling under the control of the
Cape Metropolitan Authority. The primary aim of the research was to simulate future urban
expansion of Cape Town based on past growth patterns by making use of cellular automata
methodology in the SLEUTH modeling platform.
The following objectives were explored, namely to: a) determine the impact of urbanization on the
study area, b) identify strategies for managing urban growth from literature, c) apply cellular
automata as a modeling tool and decision-making aid, d) formulate an urban growth policy based on
strategies from literature, and e) justify SLEUTH as the desired modeling framework from
literature. An extensive data base for the study area was acquired from the product of a joint
initiative between the private and public sector, called “Urban Monitoring”. The data base included:
a) five historical urban extent images (1977, 1988, 1993, 1996 and 1998); b) an official urban buffer
zone or ‘urban edge’, c) a Metropolitan Open Space System (MOSS) database, d) two road
networks, and d) a Digital Elevation Model (DEM). Each dataset was converted to raster format in
ArcEdit and finally .gif images were created of each data layer for compliance with SLEUTH
requirements. SLEUTH processed this historic data to calibrate the growth variables for best fit of
observed historic growth. An urban growth forecast was run based on the calibration parameters.
Findings suggest SLEUTH can be applied successfully and produce realistic projection of urban
expansion. A comparison between modelled and real urban area revealed 76% model accuracy. The
research then attempts to mimic urban growth policy in the modeling environment, with mixed
results.

Woodstock small business development initiatives : an impact studyRas, Waleed January 2016 (has links)
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2016. / This research study explored perceptions which small business owners and managers have of the impact that initiatives, aimed at revitalisation, have on small business development. The Woodstock Salt-River Revitalisation Framework (WSRRF, 2002) served to guide these initiatives in order to achieve their various objectives, which included, inter alia, the development of small business. Often, official initiatives cannot adequately meet the needs of all stakeholders. The benefits that are derived from these initiatives may differ amongst stakeholders owing to their varying expectations and perceptions.
The main research problem that was identified relates to reasons why the impact of this framework initiative is currently not appropriately understood and, as a result, not effectively and efficiently implemented. Hence, this research study evaluates the extent to which the Revitalisation Framework has affected the development of small businesses within the study area.
