Quick Revision: The ‘Nadi Sanjeevani’ initiative integrates scientific desiltation of water bodies with the utilisation of excavated silt in National Highway projects, aiming for enhanced flood management, agricultural land conservation, and sustainable infrastructure development.

Why is this in the news?

The Ministry of Road Transport and Highways (MoRTH) and the Government of Bihar have formally entered into a Memorandum of Understanding (MoU) for the scientific desiltation of identified rivers and other water bodies within Bihar. This collaborative initiative aims to utilise the excavated silt in ongoing and prospective National Highway construction projects, thereby integrating river rejuvenation with infrastructure development under the ‘Nadi Sanjeevani’ initiative.

Background

• Bihar frequently experiences severe flooding, particularly from rivers originating in Nepal, which deposit substantial quantities of water and silt.
• Accumulation of silt in riverbeds and water bodies significantly diminishes their water-holding capacity, exacerbating flood risks and impacting agricultural land and property.
• Traditional methods of silt management have often been insufficient to address the scale of the problem, leading to recurring environmental and economic challenges.
• The ‘Nadi Sanjeevani’ initiative conceptualises a synergistic approach where river rejuvenation efforts contribute directly to the availability of construction material for infrastructure projects.
• The ‘Bihar Jal Srot Punaruddhar Evam Gad Prabandhan Niti, 2026’ (Bihar Water Source Rejuvenation and Silt Management Policy, 2026) has been formulated to provide a structured framework for water body rejuvenation and silt management, including the removal of sand and silt from agricultural land post-floods.
• This MoU represents a significant policy shift towards a circular economy model, where waste (silt) from one sector (water management) becomes a valuable resource for another (infrastructure development).

The ‘Nadi Sanjeevani’ Initiative and Silt Management

• The ‘Nadi Sanjeevani’ initiative is a collaborative endeavour between the Ministry of Road Transport and Highways and the Government of Bihar.
• Its primary objective is the scientific desiltation of identified rivers and other water bodies in Bihar to restore their water-holding capacity.
• The initiative seeks to improve water flow and drainage systems, thereby mitigating the risk and severity of floods in the region.
• A crucial component involves the utilisation of the excavated silt as a sustainable raw material for the construction of National Highway projects.
• This approach aims to reduce reliance on fertile agricultural soil and other conventional materials for construction, thereby conserving agricultural land.
• The initiative is projected to contribute to cost reduction in highway construction and accelerate project completion by ensuring a readily available material source.
• It is envisioned as a mutually beneficial arrangement where river rejuvenation supports infrastructure development, and infrastructure development provides an economic use for desilted material.
• The implementation will involve rigorous technical assessments and necessary safety protocols, ensuring environmental sustainability and structural integrity.

UPSC Value Addition

Prelims Practice Questions

Q1. Consider the following statements regarding the ‘Nadi Sanjeevani’ initiative:
1. It aims to enhance the water-holding capacity of rivers and water bodies.
2. It proposes to utilise scientifically dredged silt in National Highway construction projects.
3. The initiative is exclusively focused on flood management in the Gangetic plains.
How many of the above statements are correct?

1. Only one
2. Only two
3. Only three
4. None

Answer: Only two — Statement 1 is correct as the initiative aims to restore water-holding capacity. Statement 2 is correct as it integrates silt use in highway projects. Statement 3 is incorrect as the initiative has broader objectives of river rejuvenation, agricultural land protection, and sustainable resource provision, not exclusively flood management in the Gangetic plains.

Q2. Assertion (A): Scientific dredging of silt from water bodies can significantly reduce the risk of floods.
Reason (R): Silt deposition reduces the water-holding capacity of rivers, exacerbating flood situations.
Select the correct option:

1. Both A and R are true, and R is the correct explanation of A.
2. Both A and R are true, but R is not the correct explanation of A.
3. A is true, but R is false.
4. A is false, but R is true.

Answer: Both A and R are true, and R is the correct explanation of A. — Assertion (A) is true because scientific dredging improves water flow and drainage, thereby reducing flood risks. Reason (R) is also true as accumulated silt decreases a river’s capacity to hold water, leading to overflow and flooding. R correctly explains A.
