PROJECTS UNDER PRITHVI SCHEME
प्रव तथ: 04 DEC 2025 5:01PM by PIB Delhi
Total budget allocation of the PRITHVI scheme since its approval is Rs. 1385 Crores (Rs. 685.00 for FY
2024-25 and Rs 700.00 Cr for FY 2025-26), out of which actual expenditure has been Rs. 1194.56 crores
as on date (Rs. 663.82 in FY 2024-25 and Rs 530.74 Crores in FY 2025-26).
Research projects are primarily supported under the REACHOUT sub-scheme of the PRITHVI scheme.
The state-wise and year-wise data on research projects funded under PRITHVI is tabulated in Annexure I.
For climate modelling, the Ministry has developed several high-resolution models targeting various spatial
and time scales including indigenously developed Bharat FS (Bharat Forecasting System) Global model at
a highest resolution ~6 KM, Highest resolution short-range (forecast upto 10 days) ensemble prediction
system, seasonal coupled dynamical Prediction model (with highest resolution of 38 km) for predicting
seasonal mean monsoon rainfall over India. The inferences from climate models and extensive research
put forward also gives immense information on the climate resilience and how to tackle the risks
associated with the changing climate over India and globally.
In ocean research, the optimal ocean observing network, Unified Ocean Modelling Framework for
operational Ocean Prediction, Sea Level Projection, and Ocean Re-analysis are used to build a Digital
Twin of the Ocean that can be effectively used for disaster prediction. The sea level rise, extreme sea
levels and tidal inundations generated from climate change scenarios are used to assess the impact along
the coastal zones.
Furthermore, advanced warning services related to Tsunami, High Wave Alerts, Strom Surges, Oil Spills,
Harmful Algal Blooms, Coral Bleach Alerts, Small Vessel Advisory etc. are provided to all coastal
population living along vast coastline of India.
In the domain of seismology, densification of the Indian National Seismological Network has increased
the accuracy in locating earthquake epicentres and estimating magnitudes, especially in seismically active
regions. In addition, seismic microzonation of 12 cities have been completed for mitigating the disastrous
impacts of earthquakes towards reduction of earthquake risk. Out of that, microzonation report of 4 cities
(Bhubaneswar, Chennai, Coimbatore and Mangalore) has also been released.
