Regional Rural Banks (RRBs) were established to provide credit and other banking facilities to rural and semi-urban areas. Land Development Banks (LDBs), now known as State Co-operative Agriculture and Rural Development Banks (SCARDBs), primarily provide long-term credit for agricultural and rural development purposes, including land improvement and farm equipment acquisition. While NABARD plays a crucial role in refinancing and policy formulation for rural credit, it does not typically provide direct credit assistance to individual rural households; its role is more at the institutional level.
