When Manhattan Minerals proposed an open pit gold mine in the town of Tambogrande, local residents came together and stopped the project. The San Lorenzo valley is a lush oasis in Peru’s barren desert coast. The area was transformed into an important agricultural centre with the installation of a World Bank-financed irrigation system. Area residents were concerned that the environmental risks associated with gold mining would threaten their thriving agricultural economy. The municipality held a popular referendum on the proposed project – the first referendum of its kind in the world. The vote, which was monitored by international observers, registered virtually unanimous opposition to the mine. The Tambogrande referendum, which played a vital part in halting the project, has since been replicated by other communities threatened by mining projects.
