Dry mining in Brazil: A cost-benefit analysis after the tragedies of Mariana and Brumadinho

By Pedro Gagliardi

[24 min read]

SUMMARY

This paper examines the costs and benefits of dry processing and/or dry stacking as alternative production methods for the current mining operations in Brazil. Both methods prevent the formation of tailings dams, which are created as a result of the extraction of iron ore. This paper carries out a cost-benefit analysis which tries – firstly – to quantify the benefits for society of avoiding tailings dam collapses like Marina in 2015 and Brumadinho, in 2019, and – secondly – estimate the cost related to investing in dry processing methods for mining; the changes in production costs; and the cost of decommissioning current tailing dams.

Brazil’s Complicated Relationship with Money

By Nathaniel Archer Lawrence

When I tell Brazilians I teach financial education, nearly without fail their first response is, “Oh, I need that.”

Brazil finds itself almost a decade into an existential economic crisis[1]. The “social-democratic” darling of BRIC countries in 2010, Brazil has spent the better part of this decade suffering. From the deepest recession in a century to unending political corruption scandals, Brazilians were unprepared for such a financial challenge. This is exactly what financial education strives to correct – at least, on paper – and what Brazil needs. Continue reading “Brazil’s Complicated Relationship with Money”

Game of Thrones and Climate Change: Brace yourselves, Summer is Coming!

By Cassia Moraes

Imagine a world where different political clans fight for increasing their power while ignoring a threat never seen before – and which can annihilate their societies without much consideration for man-made boundaries. The narrative above could be an introduction for the eighth and final season of Game of Thrones, to be released soon, in which the fate of Westeros will be sealed as the army of the dead finally make its way through “The Wall”. It could also be an accurate description of the current state of world politics, where names such as Donald Trump and Jair Bolsonaro wage a war against multilateralism at the moment which we needed it the most. Political distractions as billionaire walls and celebration of past dictatorships occupy their agenda while the real – and potentially irreversible – threats posed by climate change are already in our backyards.

While in HBO’s show the Great Houses fail in addressing the major danger Westeros has ever faced, in real life the scenario is not much different. Those who have historically been the main contributors to climate change do not take the proper actions to offset their actions. In turn, emerging countries like Brazil and China, today’s major emitter of greenhouse gas, use the poor response from developed countries as an excuse to postpone their own actions. Although the principle of common but differentiated responsibilities reinforces emerging countries’ position, they will also be losers if we fail to tackle climate change as a global community. Perhaps the metaphor of white walkers makes it easier to understand why the prisoner’s dilemma strategy of maximizing individual benefits is an illusion. If Westeros lose the war against the white walkers there will be no throne for Cersei or anyone to sit in.
