RESUMO Há uma hegemonia na produção de conhecimento associada à concentração de poder e exclusão cognitiva, cerceando o diálogo com saberes marginalizados que podem ser fundamentais para a sustentabilidade na necessária reconexão local-global. Para romper com esse contexto consideramos que ecologia de saberes, reflexão, e auto-organização podem ser promovidas por meio de pesquisas participativas, em que analisamos três distintas experiências para identificar interações intersetoriais e interdisciplinares, e diálogo envolvendo diferentes atores sociais em níveis organizacionais distintos. Com isso, arguimos que a natureza de processos participativos e dialógicos viabiliza a democratização de saberes, o engajamento e a diversidade de soluções compatíveis com os desafios da sustentabilidade.

ABSTRACT There is hegemony in the production of knowledge, associated with the concentration of power and cognitive exclusion, restricting the dialogue with marginalized knowledge that can be fundamental for sustainability in the requisite local-global reconnection. To break from this context, we believe that ecology of knowledge, reflection, and self-organization can be promoted through participatory research, whereby we analyze three distinct experiences to identify interdisciplinary and intersectoral interactions, as well as a dialogue among different social actors at distinct organizational levels. We thus argue that the nature of participatory and dialogical processes enables democratization of knowledge, engagement and diversity of solutions compatible with the challenges of sustainability.

Abstract Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth’s climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review presents the main impacts of Amazon deforestation on infectious-disease dynamics and public health from a One Health perspective. Because Brazil holds the largest area of Amazon rainforest, emphasis is given to the Brazilian scenario. Finally, potential solutions to mitigate deforestation and emerging infectious diseases are presented from the perspectives of researchers in different fields.
