Read MoreDemocratisation of water management - The experience of Tamil Nadu with governance reforms
Through these three papers, the authors argue that the solutions to the global water crisis do not lie in investing more and more money into the water sector or in the introduction of better technology. Nor is the introduction of the private sector and the reduction in the role of the government going to help. Rather, the time has come to introduce changes at the basic or the fundamental level in the way in which the water sector functions.
There is an urgent need to bring about reforms in governance by moving towards decentralisation and democratisation, leading to involvement of people from all the sections of the society, who know and understand that they are responsible for the system and its functioning, as well as by introducing principles of equity and social justice. The papers demonstrate the successful implementation of this approach by describing the experience of Tamil Nadu at democratising water management through introduction of reforms at the level of governance, through involvement of the Tamil Nadu Water Supply and Drainage Board (TWAD).
