Cumulative Impact Analysis and Nam Theun 2 Contributions

View Document 

The Nam Theun 2 (NT2) Hydropower Project is the largest infrastructure development project in Lao People’s Democratic Republic (PDR). As a result of the potential impacts the project may have on the development of the area, international funding institutions have requested a Cumulative Impact Assessment (CIA) in order to analyse the combined impacts of a number of projects, either implemented together or in a sequence and of future developments and plans, in relation to NT2. The CIA includes:

  • Effects other (future) developments in the area have on the type and magnitude of the NT2 impacts. (Added impacts)
  • Impacts of development in other sectors that are induced by NT2 activities and its supplementary components. (Induced impacts)
