Bibliography: leaves 341-389. / The central aim of this research is to evaluate the claim by members of the Coloured population of the Western Cape that they are as socially and economically marginalized under the current government as they were under apartheid. The purpose of this is to contribute to the debate on post-apartheid social transformation and broader debates on the continued use of the notion of Colouredness in the South African context. The research findings are based on fieldwork carried out in four main high schools in Coloured communities in the Western Cape province. This thesis first establishes the broad theoretical, political and historical background of the research. This section of the thesis debates the nature of Colouredness and the existing theoretical frameworks for the analysis of Coloured identities. Following this Coloured experiences of post-apartheid education policy and provision are considered. Within this analysis the evidence for claims of marginalization is discussed and its nature and intention is assessed. From this basis, the thesis then investigates the reactions of pupils to this perceived marginalization, in terms of their attitudes towards education, their aspirations and their attitudes towards other pupils. A final part of the analysis considers the nature of school and community responses to pupils' reactions to their perceived marginalization. This section investigates not only the nature of the responses, but also seeks to provide explanations for these responses, using the theoretical frameworks of the earlier sections. Finally, this thesis draws conclusions based on the original questions posed and then points to the wider implications of this research in the South African political and international theoretical contexts.

The Mexican Caribbean tourism sector is highly exposed to hurricane activity, yet coastal tourism is also a major driver influencing regional biophysical and social vulnerability to climate risks. Drawing on a political ecology approach and a vulnerability assessment, this study asks how experiences with extreme hurricane events in the Mexican Caribbean shape climate change adaptation in the regional tourism sector. This study uses multiple methods, scales and field sites to (a) examine how biophysical vulnerability to extreme hurricanes affects the tourism sector, (b) explain the changing conditions of social vulnerability linked to hurricane damage in the tourism sector and (c) assess the present and future opportunities and obstacles for adaptation planning. The main findings show that the region is experiencing a phase of unprecedented high intensity hurricanes. It is uncertain, however, whether changes in hurricane activity exceed natural multi-decadal variability. Tourism is one major driver of land use changes which have resulted in some of the world’s fastest increase in coastal urban sprawl. Most tourism infrastructure is located in areas with the greatest exposure to hurricanes. Hurricane Wilma which hit the region in 2005 is the most expensive natural disaster in the history of the Mexican insurance industry. Hotels have showed a high ability to recover operations after hurricanes. There is a high penetration of insurance ownership in hotels and there is substantial mobilization of public and private financial and human resources during hurricane disasters. Hotel responses to hurricanes, however, tend to be reactive and autonomous. One important consequence of hurricanes is that hoteliers in the interest to reduce operational costs, fire those workers with the weakest labour rights. Thus, hotel workers suffer from ‘double exposure’, a situation where hotel workers are confronted with the consequences of climate change while simultaneously suffering the consequences of globalization and neoliberal policies which have reduced the power of unions and weakened access to social security. The Mexican government has created a national climate change strategy and its operational programme which has led to the consolidation of an adaptation organizational structures at the national and state levels. I conclude, however, that adaptation planning may not result in the necessary actions on the ground since local actors are not well integrated yet into such efforts. This study shows the importance of regional adaptation research that takes into account perspectives from both the physical and social sciences. This study highlights the importance of interactions between local actors, the larger socioeconomic and political economy context to inform adaptation planning and policy.

Success or failure of climate policies in limiting warming to beneath particular thresholds depends on several physical, economic and social uncertainties. Whilst scenario analysis can be informative as to the types of policies that are required to achieve these goals, the complexity of scenario analysis often masks the underlying fundamental choices. This dissertation introduces the concept of the ‘decarbonization identity' to simply and systematically describe the mutually exclusive and collectively exhaustive range of choices available in future climate policy decisions. The simple identity states that the remaining carbon budget [B] for a given level of warming can be partitioned into four areas: the already committed 'baked-in' emissions from existing capital stock [E]; new commitments arising from investments in additional capital stock yet to be made [N]; less the stranding of existing or future capital stock [S]; and the additional atmospheric space created by negative emissions technologies (NETs) [A]. This dissertation finds that currently operating electricity generators [E] would already emit more CO2 (~300 GtCO₂) then is compatible with currently available generation-only carbon budgets [B] for a temperature rise of 1.5-2°C (~240 GtCO₂). In addition, the current pipeline of planned fossil fuel power plants would add almost the same amount [N] of emission commitments (~270 GtCO₂) to this capital stock again. Finally, these carbon budgets are inherently uncertain and depend on future, yet to be achieved, reductions of short-lived climate pollutant (SLCP) emissions. Should those reductions not be achieved today's remaining carbon budgets could be up to 37% smaller. Policymakers have now five choices to achieve the Paris climate goals: (1) protect and enhance carbon budgets by early and decisive action on SLCPs; (2) retrofit existing power generators with carbon capture and storage (3) ensure that no new polluting capital stock is added; (4) strand a considerable amount of global electricity generation capacity; and (5) create additional atmospheric space by scaling up NETs. Over the coming years and decades, the challenge will be to identify the most efficient balance of these options.
