The interlinking of rivers is a concept that involves connecting different rivers through a network of canals and reservoirs. This approach aims to address various challenges related to water management, including droughts, floods, and interrupted navigation.

Thinkers Views on Interlinking of Rivers

•   Medha Patkar: Opposition to interlinking of rivers due to ecological and social concerns. Argues that interlinking rivers can lead to environmental degradation, displacement of communities, and loss of livelihoods.

•   Mihir Shah: Support for interlinking of rivers with proper planning and governance. Believes that interlinking rivers can help address water scarcity and improve water availability for irrigation and drinking purposes.

Interlinking of Rivers: A Solution to Droughts

•   Water transfer: Interlinking rivers allows for the transfer of water from surplus regions to drought-prone areas, ensuring a more equitable distribution of water resources.

•   Groundwater recharge: By diverting excess water from flood-prone regions to water-scarce regions, interlinking rivers can help replenish groundwater levels, mitigating the impact of droughts.

•   Irrigation support: The interlinking of rivers facilitates the availability of water for agricultural purposes, enabling farmers in drought-affected regions to sustain their crops and livelihoods.

•   Hydroelectric power generation: The interconnected river system can harness hydropower potential, providing a reliable source of electricity during drought periods.

•   Improved water supply: Interlinking rivers can enhance the availability of drinking water in drought-prone areas, ensuring the basic needs of the population are met.

Interlinking of Rivers: A Solution to Floods

•   Floodwater diversion: Interlinking rivers can redirect excess floodwater to reservoirs or other water bodies, preventing inundation of flood-prone areas and minimizing damage to infrastructure and livelihoods.

•   Flood control infrastructure: The interconnected river system can incorporate flood control structures such as dams, embankments, and levees, effectively managing and regulating water flow during heavy rainfall events.

•   Water storage capacity: Interlinking rivers increases the overall storage capacity, allowing for the retention of excess water during flood periods and its controlled release during drier periods.

•   Erosion prevention: By regulating water flow, interlinking rivers can help prevent soil erosion caused by excessive flooding, preserving fertile land and protecting ecosystems.

•   Navigation infrastructure: Interlinking rivers can enhance navigation by maintaining a consistent water level, ensuring uninterrupted transportation of goods and reducing the economic impact of floods.

•   Flood forecasting and early warning systems: The interconnected river system can integrate advanced monitoring technologies, enabling accurate flood forecasting and timely dissemination of warnings to vulnerable communities.

Interlinking of Rivers: A Solution to Interrupted Navigation

•   Maintaining consistent water levels: Interlinking rivers ensures a continuous and regulated flow of water, preventing fluctuations that could hinder navigation due to low or high water levels.

•   Improved connectivity: The interconnected river system allows for the seamless movement of vessels between different river basins, enhancing regional and national connectivity.

•   Reduced transportation costs: Interlinking rivers can lower transportation costs by providing a reliable and efficient mode of transportation, reducing the reliance on road or rail networks.

•   Increased trade opportunities: The improved navigation facilitated by interlinking rivers can boost trade and commerce, promoting economic growth and regional integration.

•   Tourism development: The interconnected river system can attract tourists through river cruises and recreational activities, contributing to the growth of the tourism sector and generating employment opportunities.

Case Studies

•   Ken-Betwa River Link Project: This project aims to transfer surplus water from the Ken River in Madhya Pradesh to the Betwa River in Uttar Pradesh. It aims to address water scarcity in the Bundelkhand region, mitigate droughts, and provide irrigation benefits to the region.

•   Godavari-Krishna River Linking: This interlinking project aims to transfer water from the Godavari River to the Krishna River in Andhra Pradesh. It aims to address water scarcity in the Krishna basin, enhance irrigation potential, and mitigate floods in the Godavari delta region.

•   South-North Water Transfer Project, China: This mega-project involves diverting water from the water-rich Yangtze River in southern China to the water-scarce northern regions, including Beijing. It aims to address water scarcity, support agricultural development, and meet the growing water demand in the north.

•   Rhine-Meuse Delta Project, Netherlands: This project aims to interlink the Rhine and Meuse rivers to manage water levels, prevent floods, and enhance navigation in the delta region. It involves the construction of dams, canals, and flood protection measures.

•   Lesotho Highlands Water Project, Southern Africa: This project involves transferring water from the water-rich Lesotho Highlands to the water-scarce Gauteng region in South Africa. It aims to address water scarcity, provide water for industrial and domestic use, and generate hydropower.

The interlinking of rivers offers a comprehensive approach to address the multi-dimensional challenges of droughts, floods, and interrupted navigation. By providing solutions such as water transfer, flood control, improved navigation, and ecological balance, interlinking rivers can contribute to sustainable water management and regional development.
