A critical analysis of the environment impact assessment report of the 2000 MW lower subansiri hydroelectric project with special reference to the down stream ecology and people's livelihood.

The Environment Impact Assessment (EIA) report of the 2000 MW Lower Subansiri Hydroelectric Project prepared by the WAPCOS (Water and Power Consultancy Service, 2003) indicates that downstream survey was done only up to 7 km from the dam site without giving much importance to the actual scenario and avoiding some most crucial ecological aspects. In the report, insufficient records of terrestrial flora, phytoplanktons and fish diversity are given. No records of aquatic macrophytes, riparian flora, zooplanktons, avian fauna, floodplain crops, besides peoples' livelihood and diverse habitat provided by the river in its downstream are presented in the report.
