MA RESEARCH REPORT Prepared for the Department of Development Studies, University of the Witwatersrand, Johannesburg June 2016 / This research argues that food sovereignty offers a plausible alternative to the current unjust, unsafe and unsustainable food system in South Africa. In addition, it argues that food sovereignty provides important solutions to hunger and the brutalities of the food system which current policies and interventions fail to address. Food sovereignty is an ideal that originated amongst a peasant movement in the global South. This ideal and framework to address hunger has since evolved and spread to international movements, and is making great strides in advocating for change in the current broken food system. Food sovereignty has lately been adapted in South Africa as a grassroots led initiative promoted by the nascent South African Food Sovereignty Campaign (SAFSC). This research uses the SAFSC as a case study to explore food sovereignty alternatives in South Africa. It does this by using in-depth interviews and participant observation in the campaign to draw out understandings of food sovereignty particular to South African activists. It further assesses tactics and strategies the SAFSC uses, and compares these to current state, business and civil society organisations’ solutions to show how a more grassroots-led approach, using the food sovereignty framework, has the potential to address the roots of hunger. These roots of hunger are shown to be at the corporate food regime level, as has been indicated by the literature and confirmed in this research. As food sovereignty is pursued by various actors in South Africa it provides important examples of approaches by which power in the food system can be reclaimed to benefit the majority instead of a few elites, as is currently the case.

La presente tesis esta focalizada en el desarrollo de métodos analíticos para determinar la adulteración de especias culinarias con colorantes Sudan I, II, III y IV. Estos colorantes están prohibidos como aditivos para uso alimentario por la legislación europea ya que son carcinógenos. Las metodologías analíticas desarrolladas están basadas en el uso de técnicas espectroscópicas como UV-visible, Resonancia Magnética de protón y Raman junto con tratamiento multivariante de los datos obtenidos. En relación al análisis multivariante, como principal objetivo se planteó el establecimiento de modelos de clasificación y posteriormente se utilizaron diversas herramientas quimiométricas con el objetivo de mejorar los resultados de clasificación: análisis exploratorio de datos, métodos de selección de variables y procesamiento de espectros, estrategias de fusión de datos y métodos de transferencia (estandarización). / This thesis is focused at developing multivariate analytical screening methodologies for determining the adulteration of culinary spices with Sudan I, II, III and IV dyes. Such dyes are prohibited to be used as additive in foods according to the European legislation because they are Class 3 carcinogens. The proposed methodologies are based on the use of spectroscopic techniques such as UV-Visible, 1H-NMR and Raman along with multivariate data treatment. The applied chemometric tools include the establishment and application of supervised classification techniques combined with exploratory data analysis, data processing and variable selection techniques to extract the maximum possible information from the spectral data. Otherwise some strategies to improve the classification have been evaluated such as data fusion strategies and multivariate transfer (standardization) methods.
