Background
UPSC assesses knowledge of critical infrastructure management, disaster preparedness, environmental challenges like siltation, and the legislative measures taken to ensure public safety and resource longevity.
Dam safety is a critical aspect of infrastructure management and disaster prevention, involving the structural integrity, operational efficiency, and environmental sustainability of large water reservoirs. The Dam Safety Act, 2021, provides a comprehensive legal framework for the surveillance, inspection, operation, and maintenance of specified dams across India.
Facts & tables
- Siltation Impact
- Excessive siltation has reduced Tungabhadra dam's storage capacity from 133 tmc ft to about 106 tmc ft.
- Infrastructure Upgrade
- High-grade steel gates installed at Tungabhadra dam at ₹51 crore, expected to last 60 years, emphasizing preventive maintenance.
- Central Initiatives
- Union government plans to remove silt from reservoirs nationwide and expedite dam rehabilitation projects in 19 States.

Consider the following statements :
1. In India, the Biodiversity Management committees are key to the realization of the objectives of Nagoya Protocol.
2. The Biodiversity Management committees have important functions in determining access and benefit sharing, including the power to levy collection fees on the access of biological resources within its jurisdiction.
Which of the statements given above is/are correct?
* The Nagoya Protocol is an international agreement that addresses the fair and equitable sharing of benefits arising from the utilisation of genetic resources. It is a supplementary agreement to the Convention on Biological Diversity (CBD) and specifically focuses on access to genetic resources and the fair and equitable sharing of benefits derived from their utilisation. * Statement 1 is correct: In India, the Biodiversity Management Committees (BMCs) are indeed key to the realisation of the objectives of the Nagoya Protocol. The Nagoya Protocol aims at sharing the benefits arising from the utilisation of genetic resources in a fair and equitable way. BMCs play a crucial role in this by ensuring that local communities have a say in the access to and use of these resources. * Statement 2 is correct: The Biodiversity Management Committees also have important functions in determining access and benefit sharing. They have the power to levy collection fees on the access of biological resources within their jurisdiction. This is part of their role in managing and conserving biodiversity, and ensuring that the benefits derived from the use of these resources are shared equitably. Therefore, both statements are correct.
Which of the following are the key features of ‘National Ganga River Basin Authority (NGRBA)’?
1. The river basin is the unit of planning and management.
2. It spearheads the river conservation efforts at the national level.
3. One of the Chief Ministers of the State through which the Ganga flows becomes the Chairman of NGRBA on a rotation basis.
Select the correct answer using the code given below.
Statement 1 is correct. National Ganga River Basin Authority (NGRBA) is the financing, planning, implementing, monitoring, and coordinating authority for the Ganges River, functioning under the Jal Shakti Ministry. Statement 2 is correct. The mission of the organisation is to safeguard the drainage basin which feeds water into the Ganges by protecting it from pollution or overuse. In July 2014, the NGRBA has been transferred from the Ministry of Environment and Forests to the Ministry of Jal Shakti. Statement 3 is incorrect. The Prime Minister is the chair of the Authority.
Other members include the cabinet ministers of ministries that include the Ganges among their direct concerns and the chief ministers of states through which the Ganges River flows.

How is the National Green Tribunal (NGT) different from the Central Pollution Control Board (CPCB)?
1. The NGT has been established by an Act whereas the CPCB has been created by executive order of the Government.
2. The NGT provides environmental justice and helps reduce the burden of litigation in the higher courts whereas the CPCB promotes cleanliness of streams and wells, and aims to improve the quality of air in the country.
Which of the statements given above is/are correct
Statement 1 is incorrect: The National Green Tribunal (NGT) was established under the National Green Tribunal Act, 2010, passed by Parliament, making it a statutory body. Similarly, the Central Pollution Control Board (CPCB) was constituted under the Water (Prevention and Control of Pollution) Act, 1974 and is also a statutory body. It plays a key role in environmental regulation in India. Statement 2 is correct: The NGT’s primary role is to ensure the expeditious disposal of environmental cases related to forest conservation, natural resource protection, and pollution control, thereby reducing the burden on higher courts. The CPCB, functioning under the Ministry of Environment, Forest and Climate Change (MoEFCC), is responsible for monitoring water and air quality, implementing pollution control measures, and enforcing environmental laws to promote a cleaner environment. Thus, while both bodies deal with environmental protection, the NGT focuses on adjudication, whereas the CPCB handles regulatory and enforcement functions.
Therefore, the correct answer is option (b) 2 only.
Which one of the following has been constituted under the Environment (Protection) Act, 1986?
Central Ground Water Authority (CGWA) has been constituted under Section 3 (3) of the Environment (Protection) Act, 1986 to regulate and control development and management of groundwater resources in the country. Central Water Commission (CWC) - Established in 1945, the CWC is a technical organization under the Ministry of Jal Shakti. It focuses on water resource planning, development, and management in India, but its legal basis comes from other central government acts. Central Ground Water Board (CGWB) - While it works in close collaboration with the CGWA, the CGWB is a subordinate organization under the Ministry of Jal Shakti, established in 1970. It functions as the technical arm of the CGWA, providing hydrogeological data and technical expertise. National Water Development Agency (NWDA) - This autonomous agency, established in 1982 under the Ministry of Jal Shakti, operates under the Societies Registration Act, 1860. It focuses on resolving interstate water resource disputes, conducting feasibility studies for water resource development projects, and planning water transfer and linking projects.
