The Global Futures and Strategic Foresight (GFSF) team met in Rome from May 25-28, 2015 to review progress towards current work plans, discuss model improvements and technical parameters, and consider possible contributions by the GFSF program to the CRP Phase II planning process. All 15 CGIAR Centers were represented at the meeting.

  7. 7. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy C4 Rice • In search of a novel solution for increasing global rice supply*, IRRI is developing C4 Rice. • Rice is naturally a C3 species with relatively lower photosynthesis (PS) efficiency as compared to C4 species such as maize. • C4 species compartmentalizes CO2 fixation and processing in two different cells in order to avoid wasteful binding of O2 on the Rubisco enzyme *more than 100 million tons of additional rice is required by the year 2035 to meet the increased demand for rice
  8. 8. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy C4 rice module Yin & Struik, 2009 C4 routine was adapted from GECROS model Furbank & Taylor, 1995
  9. 9. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy ORYZA C4 Rice Module • C4 Photosynthesis with Farquhar approach • Energy balance for transpiration and gas exchange • N driven partitioning • Non-linear phenology-temperature function • N driven leaf and root senescence
  10. 10. C4 rice module vs. C3 Yin & Struik, 2009 Use all crop parameters of C3 rice; C4 special parameters borrowed from sorghum Transplanting system, same field management Nitrogen supply limited in the same level Potential water supply No light competition yet No pest & disease impact 67% increase in yield 50% increase in Total above ground biomass

  13. 13. • Submergence tolerant rice containing sub1 gene can tolerate transient flash flood (1-2 weeks), whereas rice varieties without sub1 gene can experience severe yield loss under such condition. +Sub1-Sub1 Swarna Swarna-Sub1 Re-transplated local variety Submergence Tolerant Rice
  14. 14. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy Submergence Tolerant Rice • Submergence sub-routine in ORYZA model is under development with initial tests showing promising results • Field experiments were conducted to support model development • The mechanistic process will allow precise quantification of yield loss considering interaction between variety characteristics and duration of flooding.
  15. 15. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy Upcoming Activities • Incorporation of C4 module into DSSAT • Finalizing C4 simulation results • Continue development of submergence module (target completion, 2016) • Simulation of multiple abiotic stress such as submergence, drought, and salinity (target completion, 2016)
  16. 16. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy Abiotic Stress: Drought Low High
  17. 17. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy Abiotic Stress: Submergence Low High
  18. 18. Global Futures & Strategic Foresight Extended Team Meeting 25-28 May 2015, Rome, Italy Abiotic Stress: Salinity Low High
