The 1977-1978 economic justice and human rights campaign in Bolivia stemmed from tensions that began with the 1952 Bolivian Revolution, which left the Nationalist Revolutionary Movement in power. This group implemented a nationalization of the tin mines, agrarian reforms, and universal franchises. These policies and reforms lasted until 1964, when a military coup led to the regime of General Barrientos. This regime clashed with miners and broke down worker power and cultivated the peasantry.
Throughout the 90s, Bolivia came under increasing pressure from the World Bank to privatize public goods in order to fulfill loan conditionality. In September 1999, in response to this pressure, the Bolivian government auctioned off the municipal water system ‘SEMAPA’ of Cochabamba, a city of 800,000 residents. When the auction drew only one bidder, the government signed water resources over in a 40-year concession to Aguas del Tunari, a foreign-led consortium of private investors dominated by the Bechtel Corporation.
