For the last 20 years PDS is working as the Centre of Relevance and Excellence (CORE) of Department of Science & Technology, Government of India. Under this programme PDS is engaged in identifying the technology gap in agriculture and allied activities and other livelihoods of the people including tribal communities. One of the major achievements of this programme is that PDS could develop and promote a number of technologies for farmers through participatory technology development. The technologies developed are mostly in the field of drudgery reduction, enterprise development, developing package of practices (PoP) in organic farming and tribal development.
