Land tenure in many parts of Brazil remains uncertain and controversial. These problems have recently been exacerbated by changes in the legal framework regulating protected areas and the land market. A particular challenge facing attempts to improve land tenure security and governance in Brazil is the lack of a single, integrated assessment of all types of lands. Here we address this problem and present a first, integrated map of Brazilian land tenure encompassing all official data sources pertaining to both public and private lands. Of the total (8.5 million km2) 36.1% of all lands are public (with 6.4% officially undesignated), 44.2% are private, and 16.6% are unregistered or with unknown tenure. Strikingly, overlaps among land tenure categories sum to 50% of the registered territory of Brazil. A clearer understanding of uncertainties in land tenure, and the spatial distribution of those uncertainties can help guide research and public policies focused on minimizing land conflicts and strengthening governance and territorial planning to improve economic, environmental and social outcomes from land use in Brazil.

The impacts of recurrent fires on diversity of fruit-feeding butterflies in a south-eastern Amazon forest
In the south-eastern Amazon, positive feedbacks between land use and severe weather events are increasing the frequency and intensity of fires, threatening local biodiversity. We sampled fruit-feeding butterflies in experimental plots in a south-eastern Amazon...
