Title : Visual analytics as a technological tool for communicating of monitoring the risk situation and dangerous alert of restinga vegetation


In 2015, in Mariana-MG, Brazil, a headwater region of the Rio Doce Watershed, the mineral tailings dam bursted, releasing an estimated 60 million m³ of tailings. The mud tailings contaminated almost the entire length of Rio Doce’s tributary, a 663.2 km impact, in addition to reaching a large extension of the Atlantic Ocean and sensitive regions in the coastal zone, such as the restinga ecosystem, duping several essential elements such as iron, manganese, copper, zinc, and others, but in high concentration they become toxic. This work proposes to evaluate the parameters that indicate the restinga's vegetation vitality, calculate the risk situation and dangerous alert, and elaborate a communication and monitoring tool technology. Species collected from 2019 to 2021 that represent the restinga's vegetation formation group were used, being Ipomoea imperati and Canavalia rosea; Allagoptera arenaria and Guapira pernambucensis; Protium heptaphyllum and Manilkara salzmannii, representing the herbaceous, shrubland, and arboreal formations, respectively. Then, a survey was carried out of the parameters that can indicate the vitality of the restinga vegetation, i) reproduction, analysing the flowering and fruting; ii) primary productivity, from photosynthesis analysis; iii) oxidative stress, analysing MDA and SOD enzyme; and iv) primary metabolism, evaluating proline and ascorbate levels.  Risk situation and danger alert were calculated by the parameters obtained, and these data were reported in interactive visual analytics, showing the results obtained in the last years. Therefore, the use of visual analytics could be able to evaluate the evolution of this environmental disaster in restinga ecossystem and useful to proposal future actions to solve the effects caused by the contamination of heavy metals.

What will audience learn from your presentation?

• The determination of parameters that act as bioindicators of plant vitality can help other researchers who wish to monitor species that may be under some type of risk;
• Risk situation and danger alert calculations can be applied to both fauna and flora that are in situations where environmental disasters have occurred;
• Visual analysis can be a didactic tool to communicate scientific data to the lay community helping to solve environmental problems.
