Bakhira Lake: 25,000-Year Record of Indian Monsoon Variability

GS Paper I – Geography | Climatology & Palaeoclimate

Why in News?

Researchers reconstructed nearly 25,000 years of Indian Summer Monsoon (ISM) variability using magnetic minerals preserved in sediments beneath Bakhira Lake in Uttar Pradesh.

What Does the Sediment Record Reveal?

• Last Glacial Maximum (LGM): Represents the peak of the last Ice Age, when global temperatures and monsoon intensity were significantly different from the present.
• Bolling–Allerod: A relatively warm climatic phase during the transition from the last glacial period towards the Holocene.
• Younger Dryas: A period of abrupt cooling that interrupted the general warming trend at the end of the last Ice Age.
• Holocene Climatic Optimum: A relatively warm period during the Holocene associated with significant changes in monsoon behaviour.
• Late Holocene: The record indicates relatively drier conditions, reflecting long-term changes in monsoon strength and regional hydrology.

About

• Location: Uttar Pradesh
• Type: Perennial oxbow/floodplain wetland
• River System: Associated with the Rapti River system.

Bankers’ Books Evidence Act, 2026

GS Paper II – Polity & Governance

Why in News?

The Bankers’ Books Evidence Act, 2026 is scheduled to come into force from 1 October 2026, following Presidential assent on 13 August 2026.

What is DILRMP?

The Digital India Land Records Modernisation Programme (DILRMP) is a Central Sector Scheme implemented by the Department of Land Resources, Ministry of Rural Development to modernise and digitise India’s land-record system.

Evolution

• 2008 – NLRMP: The programme began as the National Land Records Modernisation Programme (NLRMP).
• 2016 – DILRMP: NLRMP was converted into a Central Sector Scheme and renamed DILRMP.
• 2026–2031 – DILRMP 3.0: Focuses on creating an integrated, interoperable and GIS-enabled Digital Land Stack.

Key Components

•  Bhu-Aadhaar / ULPIN: Provides a 14-digit Unique Land Parcel Identification Number based on the georeferenced location and characteristics of a land parcel.
• NGDRS: The National Generic Document Registration System supports standardised and digital property-document registration.
• Multilingual Land Records: Promotes transliteration of land records into the 22 Scheduled Languages, improving accessibility for citizens.
• Revenue Court Integration: Links land records with revenue-court proceedings, helping track disputes and improve institutional coordination.
• NAKSHA: Uses GIS, aerial imagery, drones and GNSS technologies for mapping urban land and property.
• Digital Land Stack: Integrates cadastral maps, ownership records, registration data, court information and spatial/planning information.

Significance

• Reduced Land Disputes: Integration of textual ownership records with spatial information can reduce ambiguity regarding land parcels.
• Improved Credit Access: Reliable and updated land records can strengthen the use of land as an asset for institutional credit.
• Greater Transparency: Digitisation and interoperability can reduce information asymmetry and opportunities for manipulation.
• Better Urban Planning: GIS-based land information can support infrastructure planning, property taxation and urban development.
