  1. 2nd WCRP CORDEX South Asia Workshop, 27-30 August, 2013, Kathmandu Modeling the impact of climate change on Indian forest ecosystem with LPJ model Dr. Rajiv Kumar ChaturvediNational Environmental Sciences FellowIndian Institute of ScienceBangalore

  2. STATE OF INDIAN FORESTS Source: Champion & Seth, 1968 Source: FSI

  3. Why do we need to study forests? • Stock and sink of carbon • Ecosystem services (e.g. water resources) • Biodiversity • Timber • NTFP production • Livelihoods of forest dependent communities

  4. Key components of Climate Change Impact assessment in the LULUCF sector • Climate models • Climate change scenarios • Vegetation models • Time-steps • Spatial scale • Vulnerability index

  5. Key improvements in climate change impact assessment in the forest sector

  6. Tools/Model available for projecting the impacts of climate change on forests Statistical Models Deterministic Models Biogeochemistry Models Bio-geography Model Equilibrium/ Static Models Dynamic Model Most Advanced tool for impact assessment (Fishling et al., 2007)

  7. A TYPICAL DGVM ARCHITECTURE

  8. LPJ results from an ensemble of 14 Climate models

  9. Modeling demonstration for hands-on training Input data: Mean monthly temperature; Mean monthly precipitation and Cloudiness Outputs: Dominant vegetation; NPP; Soil carbon; Vegetation carbon etc

  10. Thanks
