1. On the project after mirsa-2
NARO is now developing the idea for a new international research project after MIRSA-2.
If realized, this “post-MIRSA” project will also support the activities of GRA-PRRG.

2. NARO’s tentative idea Title
Development of integrated mitigation technology for GHG emissions from rice paddies in Asia.
Goal
To develop integrated and sustainable technology that can simultaneously realize GHG mitigation, soil conservation, and stable rice production through harmonizing management practices on irrigation, organic matter, and chemical fertilizer.

3. NARO’s tentative idea (continue)
Subjects
Comparisons of (1) rainfed rice vs. irrigated rice, (2) different water management practices, & (3) different organic amendments (quantity & quality) at several sites.
Measurement of rice productivity, soil carbon storage, & GHG emissions.
Soil-carbon physical fractionation & isotope analysis.
Soil-carbon model simulation & improvement.
Expected outcome
30% GHG emissions reduction & soil fertility conservation while keeping/improving rice productivity.

4. Upcoming schedule
If approved in MAFF as a new project starting from FY2018,
NARO will prepare the proposal within a few months to win the competition.
Your ideas & advices are highly welcome & please contact Minamikawa.
