The Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS), popularly known as the 100 Days Employment Guarantee Programme, is one of lndia's most significant social protection and rural development initiatives. The programme guarantees up to 100 days of wage employment annually to every rural household willing to undertake unskilled manual work. Telangana has emerged as one of the best-performing states in implementing the scheme by combining employment generation with natural resource management, sustainable agriculture, and community asset creation. This study examines the contribution of the programme to rural development through a field survey conducted in Jonnalaboguda and Peddakothapally villages of Nagarkunool district. Primary data collected through household interactions and field observations are supplemented with secondary data from the Ministry of Rural Development, Government of lndia, Government of Telangana, and the Economic Survey of lndia. The findings indicate that the programme has enhanced rural employment, reduced seasonal migration, strengthened women's participation in the work force, improved water conservation, supported agricultural productivity, and indirectly promoted livestock development. The study concludes that the convergence of MGNREGS with irrigation, watershed development, and rural infrastructure programmes has significantly contributed to sustainable rural development in Telangana. It recommends strengthening community participation, ensuring timely wage payments, and expanding durable asset creation to maximize long-term benefits.
