The interlinking of rivers can provide viable solutions to the multi-dimensional inter-related problems of droughts, floods and interrupted navigation. Critically examine.
Approach · directive: “critically examine”
What it asks · Assess whether linking rivers can solve droughts, floods and navigation problems, weighing benefits against ecological, financial and federal costs.
It asks 3 things — answer each
- Examine the case for interlinking as a solution to droughts, floods and interrupted navigation
- Examine the concerns: hydrological, ecological, financial and federal
- Give a reasoned verdict and the way forward
Open with · The National Perspective Plan (1980) proposes moving surplus water to deficit basins through Himalayan and Peninsular components, with 30 identified links; Ken-Betwa is the first under way.
Cover
- Drought: Ken-Betwa to irrigate 10.62 lakh ha and supply drinking water to about 62 lakh people in Bundelkhand.
- Floods: storing monsoon peaks could moderate floods in the Ganga-Brahmaputra plains.
- Navigation and power: link canals extend waterways (National Waterways Act 2016); Ken-Betwa adds 103 MW of hydropower.
- Precedent: Periyar Diversion and Indira Gandhi Canal already move water across basins.
- Hydrology: true surplus is rare; floods peak together across basins; lean-season flows stay thin.
- Ecology and cost: deltas, wetlands, Panna Tiger Reserve; Ken-Betwa at Rs 44,605 crore over eight years.
- Federal: water a State subject; Article 262; implementation depends on States' consensus despite the Special Committee (2014).
- Verdict: case-by-case, consensual, ecologically vetted links paired with demand management.

Model answer· 363words · Minimalist IAS
The National Perspective Plan (1980) proposes moving surplus water to deficit basins through a Himalayan and a Peninsular component, with 30 identified link projects. Since 2020, the Ken-Betwa link (Cabinet approval, December 2021) has moved ahead as a test of how far this can cure droughts, floods and broken navigation.
Interlinking as a solution
- Drought: Ken-Betwa is to irrigate 10.62 lakh ha and supply drinking water to about 62 lakh people in drought-prone Bundelkhand.
- Floods: storing monsoon peaks in the Ganga-Brahmaputra basins could moderate recurring floods.
- Navigation and power: link canals can extend inland waterways under the National Waterways Act 2016; Ken-Betwa also adds 103 MW of hydropower.
- Precedent: inter-basin transfers such as the Periyar Diversion and the Indira Gandhi Canal already move water across divides.
✏️ Map to sketch in the exam · Ken-Betwa: the first river link under way
- districts: Panna (Madhya Pradesh), Chhatarpur (Madhya Pradesh), Tikamgarh (Madhya Pradesh), Banda (Uttar Pradesh), Mahoba (Uttar Pradesh), Jhansi (Uttar Pradesh) = Bundelkhand districts to be irrigated by the Ken-Betwa link (PIB 2021)
Draw on India's official outline (Survey of India boundary).
The concerns
- Hydrology: a link works only if the donor basin has a true surplus; floods peak in the same weeks across basins, so diversion cannot absorb them, and lean-season flows stay thin for boats.
- Ecology: reduced flows starve deltas, wetlands and fisheries; Ken-Betwa's dam takes forest in the core of the Panna Tiger Reserve, and submergence displaces families.
- Cost and time: Ken-Betwa alone was approved in December 2021 at Rs 44,605 crore (2020-21 prices) over eight years, while watershed works, micro-irrigation and recharge cost far less per hectare.
- Federalism: water is largely a State subject and Article 262 leaves inter-State disputes to Parliament's law; a Special Committee has existed since September 2014, yet links still wait on States' consensus.
Verdict and way forward
- Verdict: interlinking can meet specific, local deficits, but not the seasonal and spatial mismatch behind most Indian floods and droughts.
- Way forward: take up consensual links case by case, with independent environmental and social appraisal, and pair each with demand management, watershed works and groundwater recharge.
Rivers carry sediment, fish and culture as well as water; a few well-chosen, consensual links, backed by water saved on farms, will do more than a continental canal grid.
