Millions of households in Africa sit at the confluence of rapid urbanization and challenging climate conditions - making them especially vulnerable to food insecurity. Food systems in Africa must provide for an increasing number of urban residents, whilst coping with the impacts of climate variability and change. As urbanization processes continue to intensify, the connectivity between rural and urban areas is particularly important for both food and livelihood security yet remains critically understudied. Secondary urban areas are of particular concern, as they outnumber large cities in both number and cumulative population but are often marginalized in research and policy. These smaller urban areas are often the most tightly connected to rural agricultural production, in proximity and their vulnerability to agricultural shocks. How food systems operate across the rural-urban continuum is of central importance for food and livelihood security. Broadly, this dissertation examines these dynamics, seeking to understand how climate shocks in rural agroecosystems impact urban food security, as well as the reciprocal processes through which urban growth and urban food demand alter the function of rural-urban food systems. This work focuses on rapidly urbanizing secondary urban areas in southern Africa, which represent 85% of the total urban population in the region. The goals of this dissertation are threefold: 1) Quantify the patterns and drivers of urban population growth in secondary urban areas; 2) Examine the relationships between climate, geographic, and population-based variables, and food price volatility in urban areas and 3) Identify important rural-urban linkages and household food sourcing strategies used to cope with food price volatility in secondary urban areas. Across southern Africa, communities and nations are struggling to meet increasing food demand across a range of spatial scales. This dissertation highlights the need for solutions to cope with the impacts of climate change and rapid urbanization. More than half of the global population currently lives in urban areas, and the functioning of rural-urban food systems is of critical importance to ensure sustainable development and food security.
