  • The need for developing BNI function as a strategic research initiative to mitigate climate change while reducing N losses and improving nutrition use efficiency (NUE).
  • Providing a research platform for BNI research and cooperation with JIRCAS at CG level.
  • Funding arrangements to facilitate research cooperation on BNI with JIRCAS at a bilateral level and multi-lateral involving cross-CRP linkages. 
  • Tsukuba declaration for BNI research (by JIRCAS).
