Debating Womanhood,Defining Freedom: The Abolition of Slavery in 1880s Rio de Janeiro

This article demonstrates how both the agency of women of colour and a particular set of ideas about femininity and maternity played an important part in shaping the ending of slavery in the city of Rio de Janeiro. It does so through the prism of untapped municipal documentation, exploring initiatives taken by the city council both to abolish slavery by emancipating mainly women and to shape the city's first generation of fully free working families by founding schools and charitable institutions. In enacting these measures, councillors found themselves debating not only the meanings of freedom, but the meanings of ex‐slave womanhood. Their discussions reflected both the long‐term development of ‘free womb logic’ in Brazilian slavery and emancipation, and tendencies by the 1880s abolitionist movement to make emotive, ‘feminised’ appeals for elite women to sympathise with enslaved mothers. The article explores how women of colour used elite discourses about freedom, maternity and womanhood in order to achieve freedom, but also contested and reshaped them as they sought to bring their own lived meanings to freedom.     

New views on an old forest: assessing the longevity, resilience and future of the Amazon rainforest

The aim of this paper is to investigate the longevity and diversity of the Amazonian rainforest and to assess its likely future. Palaeoclimate and palaeoecological records suggest that the Amazon rainforest originated in the late Cretaceous and has been a permanent feature of South America for at least the last 55 million years. The Amazon rainforest has survived the high temperatures of the Early Eocene climate optimum, the gradual Cenozoic cooling, and the drier and lower carbon dioxide levels of the Quaternary glacial periods. Two new theories for the great diversity of the Amazon rainforest are discussed – the canopy density hypothesis and the precessional-forced seasonality hypothesis. We suggest the Amazon rainforest should not be viewed as a geologically ephemeral feature of South America, but rather as a constant feature of the global Cenozoic biosphere. The forest is now, however, entering a set of climatic conditions with no past analogue. The predicted future hotter and more arid tropical climates may have a disastrous effect on the Amazon rainforest.
