An attempt has been made in this paper to study the linkage between decentralisation and poverty reduction with special reference to panchayati raj institutions in Tamil Nadu. The policy implication of the study emphasises that the process of decentralisation should be designed and implemented so as to achieve required reduction in poverty. In the globalised era, decentralization has attracted significant interest in recent years. Decentralization is being seen as one of the missing institutional link between economic growth and distributive justice. Decentralisation is linked to poverty reduction in many ways. While decentralization has become a development strategy of many developing countries, its linkage to poverty reduction in particular has been the subject of recent time. In India, where social and rural sector are still backward and further affected by the ongoing liberalisation, privatisation and globalisation process, even high growth rates and innumerable poverty eradication schemes of the union as well as the state governments have failed to ensure distributive justice and left millions in sustained deprivation. Panchayati raj institutions could be a promising institutional link to combat poverty in terms of efficient designing and effective targeting.
