- Description: One explanation for the increasing prevalence of stunting in South Africa over the past 15 years while other development indicators have improved is that Big Food retail chains have been contributing to a low quality diet across the country, particularly in poor urban households. We thus use nationally representative longitudinal data (2008–2014) to trace 6 years of stunting’s evolution among South African children, adolescents, and young adults aged 0–19, with particular attention to how the prevalence of under-nutrition differs between urban and rural areas and how the drivers of poor nutrition vary spatially. The results of our random-effects logistic regressions on the nutritional impact of household agricultural production suggest that, conditional on household income, subsistence farming is associated with a lower probability of stunting. Even more important, although under-nutrition retains a strong spatial component, once observable differences in living standards are controlled for, the higher tendency for children in deep rural households to suffer from (severe) stunting reverses.

- Description: Detailed geochemical and field data for the volcanic sequence and intrusions of the Etendeka Igneous Province are used to construct a stratigraphic framework for petrogenetic interpretation of the evolution of the Etendeka-Paraná continental flood volcanic event. Geochemical and petrographic characterization of over 1,000 analyzed samples allows 8 mafic and 17 silicic magma types to be recognized.
