Due to the heterogeneity among households across locations, predicting the impacts of stay-at-home mitigation and lockdown strategies for COVID-19 control is crucial. In this study, we quantitatively assessed the effects of the Namibia government's lockdown control measures on food insecurity in urban informal settlements with a focus on Windhoek, Namibia. We developed three types of conditional regression models to predict food insecurity prevalence (FIP) scenarios incorporating household frequency of food purchase (FFP) as the impacting factor, based on the Hungry Cities Food Matrix. Empirical data were derived from the 2017 African Food Security Urban Network (AFSUN) Windhoek study and applied univariate probit and bivariate partial observability models to postulate the relation between food insecurity and FFP within the context of stay-at-home disease mitigation strategy. The findings showed that FFP was positively correlated with the prevalence of food insecurity (r = 0.057, 95% CI: 0.0394, 0.085). Daily purchases portrayed a survivalist behaviour and were associated with increased food insecurity (coeff = 0.076, p = 0.05). Only those who were purchasing food twice monthly were significantly associated with reduced food insecurity (coeff = −0.201, p = 0.001). Those households in informal settlements were severely impacted by food insecurity (coeff = 0.909, p-value = 0.007). We conclude that public health compliance should precede with cash or food support to poor households in balance with the need for long-term placement of control measures to fully contain COVID-19 or related infectious diseases.

The understanding of food security has seen major shifts since the original conceptualisations of the challenge. These changes in understanding have been accompanied by different food security measurement approaches. Despite the fact that the world has become increasingly urbanised and the developing world in particular, is experiencing its own urban transition, changes in food security measurement remain predominantly informed by a rural understanding of food security. In instances where urban measurement does take place, rural-oriented measurement approaches are adopted, occluding critical urban challenges and systemic drivers. This paper begins by highlighting the urban transition and attendant food security challenges in the Global South. It then reflects on existing food security measurement methods, detailing the positive components but also highlighting the shortfalls applicable to the urban context. At the urban scale, a food system assessment is argued to be one appropriate tool to respond to urban food insecurity while at the same time providing both the “breadth and depth” to inform effective food security programming and policy interventions. Theoretically, questions of scale, context and a critique of the rural bias in food systems work are essential informants guiding the approaches applied. [ABSTRACT FROM AUTHOR]

The drivers of food insecurity in rapidly-growing urban areas of the Global South are receiving more research and policy attention, but the precise connections between urbanization and urban food security are still largely unexplored. In particular, the levels and causes of food insecurity amongst new migrants to the city have received little consideration. This is in marked contrast to the literature on the food security experience of new immigrants from the South in European and North American cities. This article aims to contribute to the new literature on South-South migration and urban food security by focusing on the case of recent Zimbabwean migrants to South African cities. The article presents the results of a household survey of migrants in the South African cities of Cape Town and Johannesburg. The survey showed extremely high levels of food insecurity and low dietary diversity. We attribute these findings, in part, to the difficulties of accessing regular incomes and the other demands on household income. However, most migrants are also members of multi-spatial households and have obligations to support household members in Zimbabwe. We conclude, therefore, that although migration may improve the food security of the multi-spatial household as a whole, it is also a factor in explaining the high levels of insecurity of migrants in the city.
