The work on small-scale gold mining led to the comparative Amazon wide GOMIAM Project funded by WOTRO (2011-2016). The full name of the project is Small-scale gold mining and social conflict in the Amazon: Comparing states, environments, local populations and miners in Bolivia, Brazil, Colombia, Peru and Suriname. It focused on environmental problems and socio-political conflicts resulting from small scale gold mining in the Amazon. Polluting activities of gold mining may threaten the livelihoods of indigenous peoples and the natural environment in general. Cross-border tensions arise when miners from one country move to another, or smuggle gold between countries. With techniques becoming more mechanized, the scale of the problems increased considerably in the past decade. See www.gomiam.org for more information on this research and policy project.
