The construction of the Akosombo Dam offers an opportunity to overcome political and economic difficulties in state-building in the early years of independence.The hydro-power generated by the dam has supplied the country's fledgling industry,increased the electrification rate and exported to neighboring countries,taking Ghana a vital step away from a single economic structure and external dependence.The image of the dam,transformed from a colonial project to a new symbol of the country,has strengthened Ghanaians'identity to the new state.Through professional bureaucracies,Nkrumah transformed the marginalized Volta River Basin society,bringing the region under state administration,increasing local people's dependence on the state and integrating the area into the country's political and economic system,thus enhanced state capacities.While the effectiveness of the Akosombo Dam in promoting state-building is constrained by the domestic and international political environment and the design flaws of the dam itself,for the time being,the Akosombo Dam still plays an irreplaceable role in the state-building of Ghana.
