OtherHealth problems related to water quality
Socio-economic ImpactsVisible: Lack of work security, labour absenteeism, firings, unemployment, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Violations of human rights, Land dispossession, Loss of landscape/sense of place
Potential: Increase in Corruption/Co-optation of different actors, Displacement, Militarization and increased police presence, Social problems (alcoholism, prostitution, etc..), Specific impacts on women

Do you consider this as a success?No
Why? Explain briefly.EIAs completed did not consider impacts downstream in Cambodia. Impacts have been felt by communities in Cambodia without restitution or satisfactory redress. Vietnamese government promised there would be no impacts to these people and there were. There is also a lack of information on the Vietnamese project site itself and the impacts felt by the Vietnamese ethnic groups in this region.

Other CommentsThere is an extreme lack of information about impacts felt to Vietnamese people and ethnic minority groups.

The level of mobilization occurring and has occurred in the past in Vietnam is almost non-existent in comparison to that within Cambodia
