Economic valuation of artisanal small-scale gold mining impacts: A framework for value transfer application

This study develops a framework for calculating the economic costs associated with the negative environmental and social impacts of ASGM in the Brazilian Amazon. Based on a literature review on impact valuations of deforestation, land degradation, and mercury contamination, the authors use multiple parameters to develop a generalizable value transfer formula. The study additionally proposes an enhancement to the model used by Bakker et al. (2021) for estimating mercury impacts on human health.
