Forms of MobilizationCreation of alternative reports/knowledge
Development of a network/collective action

Environmental ImpactsVisible: Deforestation and loss of vegetation cover, Other Environmental impacts
Potential: Large-scale disturbance of hydro and geological systems, Desertification/Drought, Floods (river, coastal, mudflow), Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion, Reduced ecological / hydrological connectivity, Loss of landscape/aesthetic degradation
OtherThe reservoir will inundate a vast area that is now covered by primary forest. Logging has already started. The dam might also disrupt the hydrology of the river.
Socio-economic ImpactsVisible: Displacement, Loss of livelihood, Specific impacts on women, Land dispossession, Other socio-economic impacts
OtherBetween 200,000 and 300,000 people have already been displaced to clean the area for the reservoir. If the dam is built, more people might be displaced. Women will also be more impacted due to their vulnerable socio-economic conditions at their household and community level.
Project StatusPlanned (decision to go ahead eg EIA undertaken, etc)
Pathways for conflict outcome / responseStrengthening of participation
Project temporarily suspended
There is no construction activities at the dam site, but the project has not been officially canceled.
Development of AlternativesLocal groups propose to cancel all the dam projects along the Salween river and look for alternative sources of energy.
Do you consider this as a success?No
Why? Explain briefly.The project is still on the government's agenda and might push it forward if a peace agreement is reached with the rebel groups.
