At the national level, which ministry is the nodal agency to ensure effective implementation of the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006?

1. The question asks for the nodal agency at the national level responsible for the effective implementation of the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, commonly known as the Forest Rights Act (FRA). 2. The Forest Rights Act primarily deals with recognizing and vesting forest rights and occupation in forest land in forest dwelling Scheduled Tribes and Other Traditional Forest Dwellers. 3. Given the focus on the rights and welfare of Scheduled Tribes and forest dwellers, the Ministry of Tribal Affairs (D) is designated as the nodal agency for overseeing the implementation of the FRA at the national level. 4. While the Ministry of Environment, Forest and Climate Change (A) is involved due to the forest context, and Panchayati Raj (B) and Rural Development (C) ministries have roles in local governance and development, the primary responsibility for the Act's implementation lies with the Ministry of Tribal Affairs.
