Barbosa, Francisco

On 5 November 2015, a large dam containing 52 million m3 of iron mining residues (tailings) collapsed in Mariana, Brazil. The collapse prompted both an emergency response, including assistance and compensation to affected people, and a short- and long-term set of mitigation measures structured in 42 programmes. These actions, determined by a group of government agencies, aim to restore and enhance the environmental quality and well-being of the affected populations.
