The plan to build a large hydro‑electric dam on the Siang River has ignited political and local opposition in Arunachal Pradesh, raising concerns over displacement and ecological impact.
The state government of Arunachal Pradesh has approved a proposal to construct a mega‑hydro dam on the Siang River, a major tributary of the Brahmaputra. The project, touted as a boost to regional power generation, is expected to generate several hundred megawatts of electricity.
Local communities, environmental groups, and opposition politicians have voiced strong objections, arguing that the dam could submerge large tracts of forest, disrupt riverine ecosystems, and force the relocation of villages along the riverbanks. They also fear that the project may affect downstream water flow into Assam.
The controversy has escalated into a political standoff, with state legislators demanding a detailed impact assessment and greater consultation with affected stakeholders. The central Ministry of Environment, Forest and Climate Change has been asked to review the environmental clearances before any construction begins.
While the state argues that the dam will reduce reliance on fossil fuels and support economic development, the opposition insists that alternative renewable options should be explored. The dispute remains unresolved, with both sides awaiting further negotiations and possible legal interventions.
The Siang River, known locally as the Dihang, holds cultural significance for the indigenous tribes of the region, adding a socio‑cultural dimension to the ongoing debate.
