This article examines the environmental conflict that developed in Freirina, Chile, between 2011 and 2012 around Agrosuper, owner of the largest agro-industrial project ever built in the country. The stench coming from the feces distressed the residents, triggering a community uprising that attracted a great deal of national attention and even compromised some political authorities. As a result, Agrosuper decided to shut down the company by the end of 2012. The Freirina case exemplifies a “David versus Goliath” dynamic, in which a community achieves a remarkably successful outcome by stopping the operation of a huge industrial facility. To analyse this outcome, the article applies Marco Giugni's joint effects model, while integrating additional conceptual frameworks to elucidate the causal mechanisms that explain the effect of this conflict.
