While the work of waste pickers advances urban sustainability, there has been little focus on how climate change impacts affect them. This paper reports on a pilot study with 61 waste pickers in Minas Gerais, Brazil to understand their perspectives on climate change impacts and actions. It explores how waste pickers experience climate change impacts at home and at work, their adaptive strategies and the specific actions and actors needed to address these impacts. Waste pickers have practical knowledge and experience of climate events. But due to precarious employment and lack of access to services, infrastructure and social support, their responses are improvised and inefficient. They require better institutional support and their proposals must be incorporated into a negotiated approach to urban resilience. Proposals such as the climate bonus – similar to the existing recycling bonus – may help address the structural drivers of vulnerability for waste pickers in Minas Gerais. [ABSTRACT FROM AUTHOR]

This article explores the onomastic universe of the parish of São José del Rei, Minas Gerais, during the period 1751–1890. The analysis draws upon a nearly complete set of parish registers of births, augmented by extensive marriage, death, and supplemental census records. The results of the research provide new information regarding patterns of naming at both the aggregate level of social groups and at the intergenerational level made accessible to study through family reconstruction. Slave, freed, and free children bore significantly different names. Family ties reached across generations through naming practices, revealing a more stable and enduring social structure.

Manganese oxide veinlets occur in high grade compact haematite ore at Fábrica in the Quadrilátero Ferrífero of Minas Gerais in Brazil. The veinlets are microbreccias of cryptomelane and minor mechanically twinned haematite, with void-infilling lithiophorite. Bulk-rock geochemistry of selected samples shows that the increased Mn content is accompanied by enrichment in Hg (to 8 ppm), as compared with Mn-free compact haematite. This Mn–Hg mineralisation within the compact haematite has hitherto not been recognised in the Quadrilátero Ferrífero and may exist in other haematite ores containing Mn. The microbrecciation is tentatively attributed to late- or post-Brasiliano tectonics and seismic activity. [ABSTRACT FROM AUTHOR]
