A series of facilitated multi-stakeholder workshops will be held quarterly at both case study sites. These interactions will be developed to foster multi-stakeholder governance (Utting 2001) model championed by the United Nations for managing risks in tailings storage.
Stochastic structural reliability analysis of the physical dam under its environmental conditions and given its known history (if available) can be used to estimate the chances of dam failure whose immediate consequences would severely impact human life, property, agricultural and environmental resources.Find out more
The risk assessment, built upon a GIS-based model with spatially explicit consideration of the local geography, will lead to accessible visualisations to support preventative decision making.Find out more
We will quantify potential secondary impacts from mining operations which can be long-lasting and insidious.Find out more
Risk does not tend to follow the traditional segregation of scientific disciplines. Disasters are never isolated events; they are a nexus of external drivers, human factors, and engineering failure.Find out more

Ricardo Cesar is a Professor and Researcher of the Federal University of the Rio de Janeiro (UFRJ), where he has been coordinating the Soil Ecology and Ecotoxicology Laboratory (LECOTOX) of the Geosciences Institute. Such Laboratory was created by him in 2015, when he became a Professor at the UFRJ. Ricardo Cesar has been working with environmental geochemistry, metal contamination and ecotoxicology of tropical soils and aquatic ecosystems since 2002, when he started my undergraduate studies.
At the LECOTOX, the main focus of his research is to evaluate the eco-health of aquatic and soil ecosystems impacted by human activities and toxic wastes (dredged sediments, sewage sludge, mining wastes, untreated domestic wastes, and others). In this context, Ricardo Cesar has been developing multidisciplinary researches using terrestrial and aquatic organisms as bioindicators of environmental quality (ecotoxicological tests, ecological risk assessments and metal bioavailability), including the uptake of toxic elements by earthworms and fish. In Brazil, multidisciplinary studies focused on metal toxicity to soil bioindicators (earthworms and soil arthropods) are still scarce. To complement and to support the interpretation of ecological and ecotoxicological data, Ricardo Cesar has been studying the biogeochemical behavior of contaminants (especially heavy metals) in soils and aquatic systems, including the influence of physical, chemical and mineralogical attributes in such processes. Last, but not least, the modelling of the risks on human health in metal-contaminated areas is also an important research line of the LECOTOX.
Since 1995, he has been conducting research and consulting in the area of tailings dam stability and stack stability for mining waste storage. The work developed involves
