The interlinking of rivers can provide viable solutions to the multi-dimensional inter-related problems of droughts, floods and interrupted navigation. Critically examine.
The ambitious project of interlinking rivers in India is presented as a panacea for the country's water woes, promising to solve the paradox of simultaneous floods and droughts. The core idea is to transfer water from surplus river basins to deficit ones, theoretically mitigating floods, combating drought, and creating inland navigation channels.
Proponents argue that this grand engineering feat could revolutionise agriculture by providing assured irrigation to rain-fed areas, boosting food security. By diverting excess floodwaters, it could save lives and property in flood-prone regions like the Ganga-Brahmaputra plains. Furthermore, a network of navigable rivers could offer a cheaper and greener mode of transport, boosting commerce and easing the load on road and rail networks. This vision presents a powerful solution to some of India's most persistent developmental challenges.
However, a critical examination reveals formidable challenges. Ecologically, it is a nightmare. Altering natural river flows can devastate aquatic ecosystems, destroy forests (as seen in the Ken-Betwa link’s impact on Panna Tiger Reserve), and impact monsoon patterns. The project entails massive displacement of communities, raising serious social justice concerns. Economically, the financial cost is astronomical, with questions about its viability and return on investment. Politically, it is a minefield of interstate disputes, as states are unwilling to be declared 'surplus' and share their water resources.
While the concept is alluring, its potential to cause irreversible environmental and social damage means we must proceed with extreme caution, prioritising smaller, localised water management solutions over such a high-risk, high-cost mega-project.
