River Basin Management Scheme: Integrated Water Governance for 2026–31

What's the News?

The Government of India has approved the continuation of the River Basin Management (RBM) Scheme for the period 2026–27 to 2030–31 with an enhanced financial outlay of ₹2,183 crore. The scheme, operated under the Ministry of Jal Shakti, shifts water governance from fragmented, project-based approaches to a unified basin-level framework—treating entire river systems, including tributaries, groundwater, and ecosystems, as single hydrological units .

What is the RBM Scheme?

• Central Sector Scheme implemented by the Department of Water Resources, River Development and Ganga Rejuvenation, Ministry of Jal Shakti.
• Core Objective: Integrated planning, sustainable use, and protection of surface and groundwater resources at the river basin level.
• Key Shift: Moves away from isolated local projects toward holistic basin-level management, covering rivers, tributaries, lakes, and groundwater as interconnected ecosystems .

Institutional Framework

The scheme operates through three key agencies:

• Brahmaputra Board:
  • Focuses exclusively on the North Eastern Region.
  • Responsible for preparing Master Plans for flood control, erosion prevention, and drainage improvement.
  • Executes anti-erosion works (e.g., protection of Majuli Island in Assam) and constructs raised platforms in flood-prone zones.
  • Promotes springshed management and indigenous water conservation practices.
• Central Water Commission (CWC):
  • Conducts topographical surveys, hydrological investigations, and prepares Detailed Project Reports (DPRs) for multipurpose projects.
  • Focuses on challenging terrains in the Indus, Brahmaputra, Barak, and Teesta basins.
• National Water Development Agency (NWDA):
  • Handles national-level water planning, specifically the Interlinking of Rivers (ILR) programme.
  • Prepares Pre-Feasibility Reports (PFRs), Feasibility Reports (FRs), and DPRs for inter-basin water transfer projects.

Components & Focus Areas

• Integrated Basin Planning: Preparation and periodic revision of Master Plans for river basins to guide irrigation, hydropower, and navigation projects.
• Scientific Survey & Investigation: Use of GIS, remote sensing, LiDAR, and drone-based surveys for topographical and hydrological accuracy.
• Interlinking of Rivers (ILR): NWDA has identified 30 river link projects, with Feasibility Reports completed for 26 and DPRs for 15.
• Flood & Erosion Control: Targeted interventions including protection of Majuli Island (Assam) and raised platforms in flood-prone North Eastern areas.
• Community-Based Interventions: Promotion of springshed management and indigenous water conservation practices among tribal communities in hilly regions .

Challenges

• Difficult Terrains: Remote locations in J&K and North East face logistical constraints and limited working seasons.
• Inter-State Disputes: Water allocation conflicts complicate inter-basin transfer plans and integrated management.
• Data Deficits: Historical lack of real-time monitoring hampers accurate streamflow predictions.
• Ecological Balance: Balancing large infrastructure (dams/canals) with river ecosystem protection remains complex.
• Fiscal Constraints: Anti-erosion works in shifting rivers like the Brahmaputra often exceed initial cost estimates .

Additional Info

• Hydrological Context:
  • A river basin is the basic hydrological unit for water resource planning in India.
  • India's drainage system comprises 20 river basin groups: 12 major basins (catchment area >20,000 sq km) and 8 composite basins.
  • The Ganga-Brahmaputra-Meghna basin is the largest, covering approximately 11.0 lakh km² (over 43% of the total catchment area of major rivers).
  • Notably, 81% of India's geographical area falls under inter-state river basins, highlighting the need for integrated governance.
• Constitutional Framework:
  • Water is a State Subject under Entry 17 of the State List (List II) of the Seventh Schedule.
  • However, Entry 56 of the Union List (List I) empowers the Central Government to regulate and develop inter-state rivers and river valleys to the extent declared by Parliament by law to be expedient in the public interest.
  • The RBM Scheme operates within this federal framework, providing central technical and financial support without infringing upon state ownership of water resources.

Constitution (131st Amendment) Bill, 2026 Defeated in Lok Sabha; Women's Reservation Delayed

What's the News?

The Constitution (One Hundred and Thirty-First Amendment) Bill, 2026, which sought to expedite the implementation of women's reservation by linking it to a fresh delimitation exercise, was defeated in the Lok Sabha. The Bill failed to secure the mandatory two-thirds majority required under Article 368 of the Constitution. Out of 528 members present and voting, 298 voted in favor while 230 voted against, falling short of the required 352 votes. Following this defeat, the government withdrew the two related bills: the Union Territories Laws (Amendment) Bill, 2026, and the Delimitation Bill, 2026.

Why Did the Bill Fail?

• Opposition's Core Argument: The Opposition bloc argued that the Bill was not genuinely about women's empowerment but was a strategic move to "redraw the electoral map of India" using outdated 2011 Census data. They contended that it unfairly penalized states that had successfully implemented population control measures.
• Caste Census Linkage: Opposition leaders insisted that any delimitation exercise must be preceded by a comprehensive caste census to ensure proportionate representation for OBCs, SCs, and STs in the expanded legislature.
• Procedural and Federal Concerns: The Bill was labeled an "attack on federalism" as it sought to alter the balance of representation among states without consensus. It also required ratification by at least half of the State Legislatures, a process that was bypassed by the central government's push for immediate parliamentary approval.
• Mathematical Deficit: The ruling NDA lacked the supermajority (two-thirds of members present and voting) needed to pass a constitutional amendment.

Implications of the Defeat

• Delay in Women's Quota: The implementation of the 106th Constitutional Amendment Act, 2023 (Nari Shakti Vandan Adhiniyam) is now effectively stalled. The 2023 Act mandates that reservation for women in the Lok Sabha and State Assemblies will only come into effect after a delimitation exercise is conducted based on the first census taken after the Act's commencement (i.e., post-2026 Census). This means the quota is unlikely to be in place for the 2029 Lok Sabha elections.
• Freeze on Lok Sabha Strength Continues: The number of Lok Sabha seats remains frozen at 543, based on the 1971 Census, as per the Constitution (Eighty-fourth Amendment) Act, 2001.
• Political Fallout: The defeat has deepened the political divide, with the government accusing the Opposition of betraying women's aspirations, while the Opposition claims to have defended the federal structure and the rights of states.

Additional Info: The 106th Amendment and Women's Representation

• Nari Shakti Vandan Adhiniyam (2023) :
  • Mandates 33% reservation for women in the Lok Sabha, State Legislative Assemblies, and the Legislative Assembly of the National Capital Territory of Delhi.
  • Includes a sub-quota for women belonging to Scheduled Castes (SC) and Scheduled Tribes (ST) within the 33% reservation.
  • Has a Sunset Clause of 15 years.
  • Stipulates that reserved seats shall be rotated after every subsequent delimitation exercise.
  • Implementation Condition: The reservation shall not take effect until the relevant provisions of the Constitution are amended to enable delimitation based on the first census taken after the 2023 Act.
• Current Representation Gap (Data) :
  • Women constitute only about 14-15% of the Lok Sabha and an average of 9% in State Legislative Assemblies, despite comprising nearly half the electorate.
  • This contrasts sharply with the Panchayati Raj Institutions, where 33-50% reservation for women has led to transformative governance outcomes in health, water, and sanitation.
• Constitutional Procedure for Amendment (Article 368) :
  • A Constitution Amendment Bill must be passed in each House by a majority of the total membership of that House and by a majority of not less than two-thirds of the members present and voting.
  • For amendments affecting federal provisions (like representation of states in Parliament), ratification by the Legislatures of not less than one-half of the States is also required before the Bill is presented for Presidential Assent.
  • No provision for a Joint Sitting of both Houses exists for resolving deadlocks on Constitution Amendment Bills.

State of India's Bats Report 2024-25:

What's the News?

• India's first-ever national bat assessment, State of India's Bats (SoIBats) 2024-25, has been released by the Nature Conservation Foundation (NCF) in collaboration with Bat Conservation International (BCI).
• The report documents 135 bat species in India, with 16 endemic species (found only in India) and 7 species listed as threatened on the IUCN Red List.
• It highlights a critical data deficit, with 35 species unassessed or data-deficient, and calls for urgent research, habitat protection, and policy integration to conserve bat diversity.

Report Overview

• Diversity Hotspots:
  • West Bengal leads with 68 species, followed by Meghalaya (66), Uttarakhand (52), Sikkim (43), and Kerala & Karnataka (41 each).
  • Haryana and Punjab record only 5 species each, reflecting low forest cover and agricultural expansion.
  • Even urban centres like Delhi host 15 species, demonstrating bats' adaptability to human-modified landscapes.
• Endemism Patterns:
  • 16 endemic species are distributed across six biogeographic zones: Himalayas/Northeast (4), Western Ghats (4), Andaman & Nicobar Islands (4), Peninsular India (2), Gangetic Plains (1), and Chotanagpur Plateau (1).
• IUCN Red List Status (Threatened Species):
  • Critically Endangered: Kolar Leaf-nosed Bat (Hipposideros hypophyllus) — known from a single cave in Karnataka.
  • Endangered: Nicobar Leaf-nosed Bat, Pomona Leaf-nosed Bat, Salim Ali's Fruit Bat, Nicobar Flying Fox, Andaman Horseshoe Bat.
  • Vulnerable: Durga Das's Leaf-nosed Bat (Hipposideros durgadasi).

Conservation Challenges & Ecological Significance

• Threats:
  • Habitat loss due to deforestation, mining, urbanisation, and climate change.
  • Human persecution driven by myths and post-pandemic stigma linking bats to zoonotic diseases.
  • Disturbance of roosting sites, especially caves and old structures critical for endemic species.
• Ecosystem Services:
  • Pollination of night-blooming plants and fruit trees.
  • Seed dispersal aiding forest regeneration and biodiversity.
  • Pest control: Insectivorous bats reduce crop-damating pests, lowering pesticide dependency.
  • Soil enrichment through nutrient-rich guano (droppings).
• Research Gaps:
  • Lack of dedicated bat research centres and bureaucratic delays in field permissions.
  • Regional bias: Most studies concentrate in the Western Ghats, leaving Northeast, Himalayas, and island ecosystems understudied.

Policy Relevance & Governance Linkages

• Legal Framework:
  • Bats are protected under the Wildlife (Protection) Act, 1972; several species fall under Schedules I and II, granting highest protection.
  • Article 48A (Directive Principles) and Article 51A(g) (Fundamental Duties) mandate environmental protection, including biodiversity conservation.
• Strategic Alignment:
  • Supports National Biodiversity Action Plan (NBAP) and National Wildlife Action Plan (2017-31) objectives on species-specific conservation.
  • Aligns with SDG 15 (Life on Land) and SDG 13 (Climate Action) through habitat preservation and climate-resilient planning.
• One Health Approach:
  • Report emphasises balancing conservation with public health: habitat disruption may increase zoonotic spillover risks (e.g., Nipah virus, linked to Pteropus fruit bats).
  • Calls for integrated surveillance in biodiversity hotspots to monitor bat-virus dynamics without stigmatising species.

Additional Info

• Bat Biology & Adaptations:
  • Only mammals capable of true sustained flight; use echolocation (20–200 kHz ultrasonic calls) for navigation and hunting.
  • Size range: Bumblebee Bat (~2g, world's smallest mammal) to Flying Foxes (wingspan up to 2m).
  • Roosting behaviour: Caves provide stable microclimates; many species also use man-made structures, including heritage monuments.
• Key Terms:
  • Endemism: Species restricted to a defined geographic area (e.g., 12% of India's bats are endemic).
  • Data Deficient (IUCN): Category indicating insufficient information for threat assessment — applies to ~26% of India's bat species.
  • Zoonotic Reservoir: Bats host viruses (e.g., Nipah, SARS-like CoVs) asymptomatically due to unique immune adaptations; spillover typically requires intermediate hosts or direct exposure.

India's First Petroglyph Conservation Park: Safeguarding Ladakh's Ancient Rock Art

What's the News?

• The foundation stone for India's first Petroglyph Conservation Park was laid in Leh, Ladakh on the banks of the Indus River, coinciding with World Heritage Day.
• The initiative, inaugurated by Lieutenant Governor Vinai Kumar Saxena, aims to protect centuries-old rock carvings (petroglyphs) threatened by unregulated tourism, infrastructure expansion, and environmental stress.
• A Memorandum of Understanding (MoU) was signed between Ladakh's Department of Archives, Archaeology and Museums and the Archaeological Survey of India (ASI) for scientific conservation and joint management.

• Petroglyph: Image/symbol created by removing part of a rock surface through pecking, carving, or abrasion (distinct from pictographs, which are painted).
• World Heritage Day: Observed annually on 18 April to raise awareness about cultural heritage preservation; 2026 theme focused on ancient art and modern conservation challenges.

Park Architecture & Conservation Strategy

• Core Objective: Create a dedicated, curated space to relocate and preserve endangered petroglyphs from isolated, vulnerable sites while enabling public access and education.
• Target Sites: Focus on isolated petroglyphs along the Indus and Zanskar river valleys, which face higher risks from road construction, blasting, and low awareness compared to clustered sites.
• Scale of Heritage: Ladakh hosts nearly 400 documented petroglyph sites, representing one of the largest collections of prehistoric rock art in South and Central Asia.
• Key Locations: Major clusters identified at Domkhar, Alchi, Chilling, Dah Hanu, and Tangtse.

Historical & Cultural Significance

• Chronological Span: Petroglyphs document human history from the Palaeolithic Age through later historic periods, showing cultural evolution.
• Iconography:
  • Early motifs: Hunting scenes, wild animals (ibex, snow leopards, argali).
  • Later additions: Buddhist symbols (stupas, mantras), trade imagery, and multilingual inscriptions.
• Linguistic Heritage: Some carvings feature inscriptions in Sanskrit, Chinese, Arabic, and Tibetan, reflecting Ladakh's role as a historic Silk Route crossroads.
• Ethnographic Value: Carvings provide insights into ancient migration patterns, belief systems, ecological knowledge, and trade networks.
