Independent group for environmental impact evaluation

Independent science, transparent science, citizen science!

The Independent Group for Environmental Impact Evaluation (GIAIA - Grupo Independente de Avaliação do Impacto Ambiental) is a citizen-science group created through social media with the aim of working on a collaborative analysis of the environmental impact resulting from the burst of a dam at an iron ore mine in the state of Minas Gerais, Brazil.
Our group was born in the midst of a controversy. The initial information released on the toxicity of the mudflow running through the basin of the Rio Doce was conflicting. Besides, the attitude of the public institutions was shy at first. That’s when we decided to form an independent group of researchers to carry out an environmental evaluation apart from any political and financial interests.
We believe that science, and the environmental impact reports, should be fully transparent, with data and analyses freely available. All citizens should have free access to all data and analyses performed.
The involvement of local communities in the scientific activities is crucial in expanding the data collection efforts. This would amplify, disseminate and add value to the resulting scientific knowledge, empowering all the people involved, and also promoting critical thinking and providing input for further political debate based on the unfolding consequences of this environmental disaster.
