Against the background of the Group Areas Act (1950) and the consequent forced removals this thesis recovers the history of Fairview, Port Elizabeth. I examine how this neighbourhood is remembered through oral histories, family photographs and memory maps, alongside archival, media and literary representations of the area at the time. I demonstrate that despite the forced removals of its residents and the physical destruction of a neighbourhood, Fairview continues to be actively re-imagined, in the present, in varied unpredictable ways. I draw upon earlier research about Apartheid forced removals and how the places affected are remembered by people who lived the trauma of forced eviction on racial grounds. I also draw upon my own qualitative research conducted in 2012 and 2013 to explore, the representation of place in both personal memories and archival material. Through this mix I present Fairview’s history of dispossession as a result of the Group Areas Act, and highlight the violence exercised through Apartheid-era legislation. However, I also present rich family and community histories comprised of meaningful relationships that were nurtured around enduring institutions which provide insight into the ‘everyday’ makings of a neighbourhood and its residents. By allowing these interconnected narratives to shape the memory of Fairview I demonstrate that recovering this history is about more than remembering an Apartheid loss. This work contributes to a broader project of refiguring and expanding the archive in post-Apartheid South Africa, a body of materials, that recognise its character as being plagued by colonial and later Apartheid biases (Hamilton, Harris and Reid, 2002: 9). I focus on broadening memories of places in which Apartheidera Group Areas removals and its destruction were imposed. To explore the multiple dimensions of these types of spaces I understand them as embodied social contexts which provide structure to inhabitants through multiple layers of community (Till, 2012: 9, 10, 2008: 108). This approach assists me to explore responses to acts of trauma like forced removals and demolitions, highlighting the various place-making activities through which people attempt to reconnect with their former neighbourhoods and lives, expressed in recollections, images and rituals which are central to how places of memory are remembered and reimagined (Till, 2003: 297). In the context of Fairview the mix of public and state archives with family repositories was central to recuperating and recovering a fuller history of Group Areas Removals and highlighting its meaningfulness in the present.

Includes bibliographical references. / Sand is a resource in high demand for urban expansion and development. Sand mining operations are often located on the edges of cities. The Macassar Dunes are an important source of building sand for the City of Cape Town. The area is located within the Cape Floral Kingdom, the smallest and richest of the six floral kingdoms of the world. The Macassar Dunes area has been identified as a core flora conservation site due to its unique habitat diversity and quality. South Africa is a developing country and this case study is used to highlight the tensions that arise between the need to provide building sand for development and the need for integrated and accountable management that allows for the sustainable functioning of natural physical and ecological processes as well as enhanced social and economic benefits for people.

Investigations draw on literatures of the state, development and critiques of South African housing policy to "sketch" the predominant characteristics of the CTCHC’s housing rationality. The contours of residents housing rationalities are explored through an engagement with literatures and case studies that stress the social and historical aspects of home-ownership.

Purpose of Impact Assessments The purpose of Impact Assessments (lAs) is to reconcile society's needs for development with its need to conserve the environment. lA aims to assist planners to devise solutions that are sustainable and equitable, but still efficient. lA falls short In practice, the influence of lA on the planning process has been called into question: its recommendations are not always implemented, and some of its mitigatory measures have been narrow and naive. The gap between lA principles and lA praxis needs to be bridged by more effective procedures. Faulty problem formulation In this dissertation it is mooted that conventional lA , procedures, including the 1992 Integrated Environmental Management procedure, pay inadequate attention to the formulation of problems. There is a danger that lAs may focus on the wrong problem, or may misconstrue the right problem. Weak problem conception may then give birth to less than optimal solutions. Flawed solutions Following the lA for Contract 1000 (access roads to the Mohale Dam), only two alternative solutions were presented to the decision-maker for consideration. Of these, the LCAR is likely to be rejected because it is associated with high risks to the integrity of the biophysical environment, and because it costs M47 million (Malotis) more to construct than does the WAR. By default, the WAR is likely to become the preferred alternative; however it is unable to address some of the fundamental problems in the project area. Selection of the WAR as the access route for transporting materials to the Mohale Dam site "creates" groups of winners and losers in the affected society. In addition, failure to build the LCAR is equivalent to a lost opportunity (ie it represents an opportunity cost) for certain other groups of "losers" [see Table Sl]. The WAR, the best solution that conventional lA could generate, is manifestly a less-than-optimal solution. A problem-solving approach Analyses of the actual procedure followed during the lA for Contract 1000, and of the conventional approach to lA (according to the literature) point to the failure of lA procedures to recognise certain crucial features of environmental problems. lA procedures are not adapted to the dynamism or the complexity of environmental problems, and are not adequately designed to take into account interrrelationships (linkages) among either affected environments or among particular problems. lA is also in danger of becoming divorced from its political ("real world") context. In an attempt to address these failings of lA, a problem-solving approach to lA is developed. The new approach to lA is based on the 1992 IEM procedure, but is supplemented by elements of the natural human problem-solving process [after Miller 1985], and is also informed by Hill and Fuggle's [1990] classification of types and levels of alternatives.

This thesis examines the extent, nature and impact of flooding in informal and subsidised housing areas on the Cape Flats. Drawing on constructivist arguments regarding the subjectivity of risk as a concept, I examine how flooding and risk are conceptualised locally and internationally, and how well these framings compare with people's experiences in subsidised housing areas in Cape Town. I show that flooding remains a significant challenge in subsidised housing areas. Flood-risk has a strong built environment component; the very dwellings that should help to improve people's lives serve instead to transform and perpetuate risk, undermining the developmental objectives of the housing programme. In so doing, I interrogate assumptions about risk, hazard and vulnerability, and the lessons for theory and practice.

Development in urban catchments often result in rivers being converted into large stormwater canals where stormwater is removed as quickly as possible to prevent flooding. A combination of elevated peak flows, increased nutrients and contaminants and reduced biotic richness are typical features of these urban waterways. This study explored the dynamics of an urban river in Cape Town by using high-resolution monitoring sensors and loggers to analyse and model real-time discharge and water quality data during and after 14 rainfall events. Discharge and water quality data were collected from the Liesbeek River at three sites during the rainfall events. As expected, the upper most sampling site had the lowest discharge and pollution load, compared to sites in the middle and lowest reaches of the river. An analysis showed significant correlations between the discharge and electrical conductivity at all three sampling sites. Rainfall was the primary factor in altering discharge and electrical conductivity. Predictive modelling using selected rainfall designs indicated that average discharge and total volume increases with increasing rainfall. Linear regression analysis for electrical conductivity indicated a strong relationship whereby an increase in discharge resulted in a decrease in electrical conductivity. This study revealed the discharge and water quality of stormwater in the Liesbeek River during rainfall events showed the improved water quality conditions in the river during the rainfall events particularly after the peak discharge. Furthermore, the implications of this study revealed that the Liesbeek River can become a water source for recharging groundwater and aquifers.

Large-scale climate processes such as El Niño-Southern Oscillation (ENSO), Antarctic Oscillation (AAO), and many others, play varying roles in regional climate variability across the world. While the role of singular processes have been explored in many studies, the combined influence of multiple large-scale processes has received far less attention. Key to this is the challenge of developing methodologies to support the analysis of multiple processes interacting in potentially non-linear ways (co-behaviour) in a particular region. This study details the development of such a methodology and demonstrates its utility in the analysis of the co-behaviour of largescale process interactions on regional precipitation and temperature variability over southern Africa. The study defines co-behaviour as the interaction of large-scale processes that may influence regional circulation leading to climate variability. A novel methodology which involves a combination of analysis techniques such as Self-Organizing Maps (SOM) and Principal Component Analysis (PCA) is developed to identify and quantify such co-behaviour which accommodates potentially non-linear interactions. This methodology is evaluated in the context of southern African regional climate using three key processes, namely ENSO, AAO and Inter-tropical Convergence Zone (ITCZ), and characterizations of regional circulation, and temperature and rainfall variability. Analysis of co-behaviour under observed conditions identifies results that concur with prior studies, in particular the dominant regional response to ENSO, but also establishes key examples of co-behaviour such as the role of the AAO in moderating and altering the regional response to ENSO which is important for understanding regional climate variability. Application of the approach to Global Climate Model (GCM) simulations of past climate reveals that while many GCMs are able to capture individual processes, in particular ENSO, they fail to adequately represent regional circulation variability and key observed co-behaviour. The study therefore clearly demonstrates the importance of co-behaviour in understanding regional climate variability as well as showing the usefulness of the new methodology in investigating co-behaviour. Finally, the new insights into evaluating model performance through the lens of core climate processes and their interaction provides a significant step forward in both model development and application for decision making.

Conventional management approaches, focused primarily on stock status and top-down driven regulatory measures, such as are employed in many commercial fisheries across the globe, have proven to be inadequate in managing small-scale fisheries and have contributed to marginalisation of this sector. In South Africa, small-scale fisheries have been increasingly recognised since the abolishment of Apartheid and the advent of democracy in 1994. Nevertheless, the management approaches implemented have been largely top-down, natural science-driven and single-species approach. South Africa's fishery sector is currently going through a historic moment where all small-scale fishers are awaiting implementation of a new Small-Scale Fisheries Policy that will see it endorsing the holistic, multi-species and people-centred approach and the recognition of local and indigenous knowledge of fisheries and addressing the complex socio-economic needs of the fishers. However, in order to implement this policy using a co-management and EAF approach, Government and fishing communities will need to set up the required information-gathering and monitoring tool that would be in line with the principles and objectives of the South African Small-Scale Fisheries Policy as careful assessment of social and economic outcomes of fisheries policies is required to support and sustain livelihoods of these fishers. A proper information management system (IMS) would further ensure that the new approaches to small-scale fisheries management are practical and effective in managing this sector. In investigating the small-scale fisheries information management system, the researcher conceptualised and designed an IMS and further conducted case studies by analysing and work-shopping results of analysed catch data recorded by an independent service provider to Doringbaai small-scale fishers, and analysed catch data of East Coast Rock Lobster in the Eastern Cape of South Africa. Based on the results of the conceptualised and designed IMS and that of the analysed catch data, it is clear that there is a need for the IMS to be converted into a web-based system and further accommodate more indicators that would assist in equipping fishers and fisheries authorities with relevant decision-making. It is also clear that there is a need for an urgent overhaul in how catch data is gathered and packaged as there were numerous errors in the data that could affect how small-scale fisheries should be managed. One of the interventions urgently needed is implementation of an electronic data capturing and instant synchronisation of data into the IMS which would present live data through a web interface customised per user type. Such tool would improve the current management measures and further contribute to improving governance of small-scale fisheries when the Small-Scale Fisheries Policy is implemented.

Most contemporary urban development in cities of the global South is responding to rapid urbanisation caused by prospects of employment opportunities and improved quality of life. Research in the field of sustainability in cities of the global South mainly focuses on economic and social development goals. However, there is an emerging sense that an appreciation of ordinary, everyday practices at the level of the community is important for developing a nuanced understanding of what sustainability might be in Southern cities. There is agreement on the need to pay attention to social and cultural practices in urban sustainability literature; yet relatively little research in the field engages closely with everyday practices at the level of neighbourhoods or communities. This is particularly true in the global South, and especially in low-income urban neighbourhoods, where developmentalist agendas dominate both academic and policy-related research. My thesis addresses this gap through an exploration of a wide range of everyday practices in a lowincome, peri-urban area, which happen to have sustainable effects. Analysing ethnographic data collected over nine months in the Cape Town township of Nyanga, I find that the desire of urban residents to create spaces of home and belonging drives behaviour that in fact has positive sustainable outcomes, yet is seldom considered in literature on sustainable cities. I argue that paying attention to how ordinary citizens ‘make home', specifically by (i) drawing on memories, (ii) developing livelihoods, and (iii) building social relations can enrich understanding not only of economic and social development but also of the complex ways in which social and environmental sustainability are already intertwined in everyday practice. Facilitating sustainable spaces in cities of the global South, therefore, requires critical engagement with the practices that are already taking place in urban residents' everyday lives.
