Evidence-based policy is increasingly important, more so in a post-truth environment. Despite past successes, Brazil still faces environmental and social challenges, including degradation of marine and terrestrial ecosystems, biodiversity conservation and poverty and inequality, among others. The political shift brought by the recent national elections has generated a climate of uncertainty particularly about the future of environmental policies.
This Focus brings together research and opinion pieces relevant to ongoing policy debates around environmental and sustainability policies in Brazil. In addition to the pieces published in this issue, the collection gathers selected articles published across Nature Research journals.
The country achieved impressive environmental and sustainability successes in the past. Now more than ever, scientists should focus on providing evidence to support policy that helps Brazil to continue doing so.
