The Bolivian gas conflict was a social confrontation in Bolivia reaching its peak in 2003, centering on the exploitation of the country's vast natural gas reserves. The expression can be extended to refer to the general conflict in Bolivia over the exploitation of gas resources, thus including the 2005 protests and the election of Evo Morales as president. Before these protests, Bolivia had seen a series of similar earlier protests during the Cochabamba protests of 2000, which were against the privatization of the municipal water supply.
