Review of Current Status of climate services for the Water Sector in India Ashvin K. Gosain Professor, Indian Institute of Technology Delhi Inter-Agency Consultation Meeting on UIP FAO, Rome

Organizations providing Climate Services (1) Indian Meteorological Department Climate Services Weather Forecasting Services Agromet-Advisory Services Hydro-meteorological Services Drought Monitoring Monsoon Monitoring & Forecasting

Organizations providing Climate Services (2) National Centre for Medium Range Weather Forecasting (NCMRWF) Medium range weather forecasting (spanning from 3 to 10 days) Mesoscale models for accurate prediction of high impact weather, such as severe thunder storms, heavy rainfall events, cyclone, etc.

Organizations providing Climate Services (3) Indian Space Research Organisation (ISRO) Meteorological and Oceanographic Satellite Data Archival Centre (MOSDAC) Weather images from Kalpana1/INSAT-3A Support to Special Observation Periods (SOPs) like launch, cyclone etc., by disseminating the data in Near Real Time All-India weather forecast

Organizations providing Climate Services (4) Indian Institute of Tropical Meteorology (IITM) Responsible for producing regional climate model output Ongoing research on clouds, aerosols, precipitation and atmospheric processes Launching National Monsoon Mission to develop dynamical prediction system for monsoon rainfall

Indias National Communications to UNFCCC Coordinated by MoEF The first communication was made in 2004 It was a multidisciplinary effort Work on water Resources was entrusted to IIT Delhi Second National Communication has just started and IIT Delhi is again leading the Water Resources work

River Basins Modeled – NATCOM II

Hydrological Simulation (SWAT) Features Physically based Distributed model Continuous time model (long term yield model) Uses readily available data Suitable for long term impact studies

Change in water balance components

Change in precipitation towards 2030s and 2080s

Change in Water Yield towards 2030s and 2080s

Change in Evapo-transpiration towards 2030s and 2080s

Change in Sediment Yield towards 2030s and 2080s

Change in monsoon drought weeks towards 2030s & 2080s

Need of the Water Sector Integrated water resource development and management framework is required to be adopted Creation of sharable information is essential for sustainable use of water resources This shall also go a long way for selecting meaningful adaptation options to climate change impacts February 28,

User Interface Platform (UIP) - Requirements Should be comprehensive to cater to diversified needs Have sector based UIPs All the data collected and used should be in public domain Every UIP should showcase what it has offered to the society Provision for validation of information

Thank you
