PARLIAMENT QUESTION: PRITHVI SCHEME
1. At a Glance
- PRITHvi VIgyan (PRITHVI) is an overarching umbrella scheme of the Ministry of Earth Sciences (MoES) that consolidates five legacy sub-schemes into a single Earth-system science programme covering atmosphere, ocean, geosphere, cryosphere and biosphere [S1][S2].
- Relevant for UPSC because it is a recurring GS-III S&T / Environment scheme, the principal vehicle for India's weather, climate, polar and seismology R&D, and was a Parliament Question (Feb 2026) in the Lok Sabha [S1].
2. Why in the News
- 5 February 2026: MoES placed the objectives and progress of PRITHVI before Parliament via a written reply, restating the scheme's mandate on Earth-system observations, climate prediction, seismic monitoring and polar/deep-sea exploration [S1].
3. Background & Evolution
- 5 January 2024: Union Cabinet, chaired by PM, approved the PRITHVI scheme for the period 2021–26 at a total outlay of ₹4,797 crore [S2].
- It subsumes five pre-existing MoES sub-schemes rather than launching fresh verticals, marking a shift to an integrated Earth-system science approach [S2].
- Builds on India's institutional ecosystem under MoES (IMD, NCMRWF, INCOIS, NCPOR, NIOT, IITM etc.), although PIB release of Feb 2026 reiterates these objectives [S1].

Sub-scheme expansions [S2]: - ACROSS — Atmosphere & Climate Research-Modelling Observing Systems & Services - O-SMART — Ocean Services, Modelling, Application, Resources and Technology - PACER — Polar Science and Cryosphere Research - SAGE — Seismology and Geosciences - REACHOUT — Research, Education, Training and Outreach
5. Multi-Dimensional Analysis
- Scientific / Technological
- Mandates long-term observation of atmosphere, ocean, geosphere, cryosphere and solid earth to capture vital signs of Earth-system change [S1].
- Develops modelling systems for weather, ocean and climate hazard prediction and for understanding climate change science [S1].
- Funds seismic hazard assessment and earthquake monitoring under SAGE [S1][S2].
- Environmental
- Strengthens India's climate change observation backbone, feeding into UNFCCC/IPCC reporting via improved Earth-system data [S1].
- PACER sub-scheme drives polar and high-seas exploration, including Arctic/Antarctic stations and deep-sea biota studies [S1][S2].
- Economic / Strategic
- Targets technology for sustainable harnessing of oceanic resources — links to Deep Ocean Mission and Blue Economy [S1].
- Cyclone, monsoon, tsunami and storm-surge advisories generated under ACROSS/O-SMART have direct fiscal value (disaster avoidance) [S1].
- Governance / Administrative
- Integration of five vertical schemes under one umbrella aims to reduce duplication and enable cross-component Earth-system modelling [S2].
- Centrally implemented via MoES institutes; no state-share component (central sector scheme) [S2].
6. Recent Developments (last 12-18 months)
- 5 Feb 2026 — Lok Sabha written reply (PIB) reiterated PRITHVI objectives and ongoing implementation [S1].
- Jan 2024 — Cabinet approval and rollout of the integrated umbrella structure [S2].
7. Prelims Hooks
- PRITHVI stands for PRITHvi VIgyan [S1].
- Implementing ministry: Ministry of Earth Sciences [S1].
- Cabinet approval date: 5 January 2024 [S2].
- Total outlay: ₹4,797 crore [S2].
- Implementation period: 2021–26 [S2].
- Number of sub-schemes integrated: Five [S2].
- Sub-schemes: ACROSS, O-SMART, PACER, SAGE, REACHOUT [S2].
- Five Earth-system components addressed: atmosphere, hydrosphere, geosphere, cryosphere, biosphere [S2].
- PACER covers Polar Science and Cryosphere Research (not seismology) [S2].
- SAGE covers Seismology and Geosciences — seismic hazard assessment [S1][S2].
- O-SMART = Ocean Services, Modelling, Application, Resources and Technology [S2].
- It is a central sector umbrella scheme (not centrally sponsored) [S2].
- Scheme objective explicitly includes exploration of polar and high-seas regions [S1].
8. Mains Relevance
- GS-III — Science & Technology (indigenous tech, R&D); Environment (climate change); Disaster Management (cyclones, earthquakes, tsunamis).
- GS-I — Geography (oceanography, cryosphere, monsoons) — peripheral.
- Sample stems:
- "Discuss how the PRITHVI scheme integrates India's Earth-system observation capabilities and its implications for climate resilience." (GS-III)
- "Examine the role of Ministry of Earth Sciences' umbrella schemes in disaster risk reduction in India." (GS-III)
- "PRITHVI scheme is more than a research programme — it is a strategic instrument for Blue Economy and polar diplomacy. Discuss." (GS-III)

10. Common Errors / Trap Areas
- Confusing PRITHVI (MoES Earth science umbrella) with Prithvi missile (DRDO/strategic forces) or PRITHVI portal of MoP&NG — different ministries.
- Wrong ministry: it is MoES, not MoEFCC or DST.
- Wrong number of sub-schemes: it is five, not four or six.
- Mixing up sub-scheme mandates — e.g., SAGE = seismology, PACER = polar/cryosphere (not vice versa).
- Treating it as a new scheme launched in 2024 — it is an umbrella consolidating ongoing schemes for 2021–26.
- Calling it a "centrally sponsored scheme" — it is central sector (100% Union funded).
