- Description: The main research problem addressed in this study is that South African cities are not effectively integrating and utilising available, and rapidly emerging smart city data sources for planning and management. To this end, it was proposed that a predictive model, that assimilates data from traditionally isolated management silos, could be developed for prediction and simulation at the system-of-systems level. As proof of concept, the study focused on only one aspect of smart cities, namely crime management. Subsequently, the main objective of this study was to develop and evaluate a predictive model for crime management in smart cities that effectively integrated data from traditionally isolated management silos. The Design Science Research process was followed to develop and evaluate a prototype model. The practical contributions of this study was the development of a prototype model for integrated decision-making in smart cities, and the associated guidelines for the implementation of the developed modelling approach within the South African IDP context. Theoretically, this work contributed towards the development of a modelling paradigm for effective integrated decision-making in smart cities. This work also contributed towards developing strategic-level predictive policing tools aimed at proactively meeting community needs, and contributed to the body of knowledge regarding complex systems modelling.

Approaches to detecting and assessing patterns, processes and responses to change in South African estuaries

- Description: The research presented indicates deep knowledge of estuary pattern-process-function across a broad range of estuary types. This study successfully developed and applied approaches to detect change at varying temporal and spatial scales in South African estuaries. This assessment was based on the physical characteristics of estuaries and predicted or measured change in the drivers of estuary health. This is the first study in the country to review and synthesise the vulnerability of South African estuaries to Climate Change on a regional scale. Through sound scientific approaches this research has advanced our knowledge on complex estuarine systems and made a significant contribution globally to approaches for the conservation and management of estuaries.

The survival of micro -enteprises in Kampala, Uganda :a substainable livelihoods approach

- Description: This purpose of this thesis was to explain the resilience of certain micro-enterprises (MEs) in Kampala, Uganda – by focusing on their vulnerability, the assets that they brought to bear on the situation, the role of non-governmental organizations and government institutions in supporting MEs, and the strategies used by ME owners, themselves. As such, it adopts the Sustainable-Livelihoods approach – an approach that has not been used in Kampala before. Thus, it makes a valuable contribution to the field. Designed as a qualitative study, it used in-depth interviews and focus-group discussions. The major findings on vulnerability were linked to: the rising cost of materials; unfair licensing; the struggle to win tenders; local and foreign competition; and the disruption of utilities. The assets used to sustain the welfare of the MEs included: making use of a range of skill-acquisition strategies; leveraging networks; and pooling resources. Financial assets used by MEs revolved around informal savings and credit schemes; but the support given to the MEs through government agencies and NGOs was difficult to assess. Several important strategies were used by ME owners. One of these involved linking with formal construction companies. In addition, temporary workshops constructed out of wood-and-iron, were common. This increased mobility and allowed the re-use of materials. Furthermore, MEs manufactured their own tools, developed new marketing techniques, and diversified their income-generating activities. The significance of this study is two-pronged. It demonstrates that the resilience of MEs does depend on their own positive qualities, but also on an increasingly business-friendly national and international economic environment.
