The consultancy service for the Thalpitigala Project involves conducting a socio-economic survey to assess the demographics, livelihoods, and social conditions of affected communities. It also includes preparing a Resettlement Action Plan (RAP) to address displacement impacts, provide fair compensation, restore livelihoods, and ensure community participation. The RAP will adhere to international standards, include a grievance redress mechanism, and outline a monitoring framework for implementation.
