Dibang, which will be built over more than 5,000 hectares (12,360 acres) of forest land, faces similar risks, according to Himanshu Thakkar, coordinator for nonprofit South Asia Network on Dams, Rivers and People. The company’s nine-year timeline is optimistic when accounting for potential delays because of local protests and geological difficulties, he said.
“The cost is going to be much higher and benefits much lower,” Thakkar said. “There’s really no viability for such projects.”
The approved investment includes 67.2 billion rupees of government support for flood moderation and enabling infrastructure, such as roads and bridges connecting the construction site.
