The Union Cabinet decision will come into effect from April this year.
Those tribals who have received land rights under the Forest Rights Act, 2006 will be eligible for additional 50 days of wage employment under the rural job scheme.
The beneficiaries would be those who have completed 100 workdays in that particular financial year.
They will be given a job card of a different colour to distinguish from the regular MNREGA workers.
Around 14 lakh individual and community titles have been distributed under FRA 2006. Of these around 8 lakh individual titles have been given in Andhra Pradesh, Chhattisgarh, Jharkhand and Orissa.
The government believes it as an important initiative since a lot of land levelling, plantation and other activities are required to be undertaken on these lands to make them more productive.
The additional persondays through MNREGA will allow the households to undertake additional work on their own land.
This is one among the several initiatives taken by the Rural Development Ministry for the uplift of the tribals.
Rural Development Minister Jairam Ramesh said though the primary focus of this raise in workdays is on the tribals, people from other communities, who are beneficiaries under the Forest Rights Act, 2006 would also be covered by the Cabinet decision.
