A dissertation submitted to the Faculty of Science, School of Computational and Applied Mathematics, University of the Witwatersrand, Johannesburg, in fulfilment of requirements for the degree of Master of Science. 10 November 2014. / This MSc thesis is aimed at assessing the food security of people actively participating in urban agriculture. In addition, it aims to assess the role of community projects that are involved in urban agricultural activities in Soweto. The fieldwork took place in five suburbs of Soweto; Meadowlands, Chiawelo, Mzimhlophe, Motswaledi and Nancefield Hostel. The findings suggest that there is a link between urban agriculture and food security in Soweto. Field based research revealed that the participants who engage in urban agricultural activities are doing so to supplement their households’ daily dietary needs. The community projects that mainly engage in food gardening are doing so for the same reasons as the individuals. However there is a greater potential for the community projects to grow into more sustainable micro-economical entities that can supply the community and local retailers with locally grown cheap vegetables. Hampering this potential is the need for continuous skills development and training in agriculture and financial management. In addition, there is a problem pertaining to access to resources and funding than could assist both the community projects and individuals to grow good quality food. There is however a need for more data to assess the spatial distribution of the urban cultivators, livestock keepers and community projects. Nonetheless, it is important to note that urban agriculture is quite significant in the lives of those involved as it has helped reduce food insecurity in their households and encourages social

Poverty and the environment are closely linked, as people use environmental resources to support livelihoods. Illegal stone quarrying evident in Lusaka, Zambia is symbolic of the use of environmental resources by the poor. Stone crushing provides income yet it is characterized by land degradation, large-scale excavation and dumping of waste materials. This study provides an analytical account of stone crushing as a livelihood in Lusaka and makes recommendations for improving the livelihoods of stone crushers to become sustainable. Using a livelihoods approach, a qualitative study collected data from various role players in Lusaka. Assets (physical, natural, human, social and political capital) for stone crushers were assessed, revealing that stone crushers lack livelihood assets, key options and are exposed to various shocks due to seasonal shifts. Increasing access to key livelihood assets, reducing vulnerability, improving infrastructure, access to justice and tackling social exclusion and gender inequality will enhance their livelihoods. / Development Studies / M.A. (Development Studies)

This study analyses the impact of land registration and certification scheme on sustainable use of farmlands in Debre Mawi and Densa Bahta rural kebeles of Amhara region in northwestern Ethiopia, with a view to contributing to the theoretical debate on tenure security and more realistic policy advocacy on the sustainable use of farmlands. Within the framework of qualitative research methodology, the case study approach helps to observe and understand the relationship between land titling and sustainable use of farmlands in Densa Bahta and Debre Mawi kebeles of the Amhara region in Ethiopia. Specific methods employed were focus group discussions, in-depth interviews and observation, complemented by context analyses of relevant documents. It was found that land titling has contributed to a high perception of security of land tenure among study respondents. However, results show that land titling has both positive and negative impacts on sustainable use of farmlands. The positive impact of land titling is ascribed to its assurance effect and legal obligation imposed on farmers to adopt proper land management practices. The negative impact of land titling arises from its failure to address the existing inequality in possession of farmlands among the village communities. Failure of farmers’ high perceptions of their security of land tenure to translate into sustainable land use practices has implications for the relative importance of productive asset endowments, self-efficacy and risk perception on the sustainable use of farmlands in the Amhara region. Interviewees that follow unsustainable farming practices were endowed with relatively lower pieces of farmland and disadvantaged in possession of other productive assets. They also demonstrated a low level of self-efficacy and a risk-averse attitude to adopting conservation technologies, as they possessed smaller sizes of farmland compared with the village and regional average. The study urges a holistic approach and comprehensive analytical framework to understand the synergy of several factors that affect the sustainable use of farmlands. / Environmental Sciences / D.
