Transparência da informação pública no Brasil: uma análise da acessibilidade de Big Data para o estudo das interfaces entre mudanças climáticas, mudanças produtivas e saúde

The transparency of public information, a right that is entitled by law in Brazil, is the basis to generate  adaptive knowledge in adverse situations, such as extreme socio-environmental vulnerability and its  impacts on human health. This article evaluates the transparency of public information in three areas – i)  human health, focusing on the Sistema Unico de Saude – SUS (Unifid Health System); ii) productive  changes (land use indicators); and iii) climate changes (rain and temperature indicators) – using data from  all the 5,570 Brazilian municipalities over the last 20 years. The experience of building a national database  (Data Lake) from available information in public (or public-private) databases – DATASUS, MapBiomas,  Instituto Nacional de Meteorologia – Inmet (National Institute of Meteorology), and Hidroweb of the  Agencia Nacional de Aguas – ANA (National Water Agency) – confimed that, in practice, the accessibility  of public information in Brazil suffrs from signifiant shortcomings. We include some recommendations  for and how it could be improved so that the access rights to information becomes a more concrete reality  for the Brazilian citizen.
