This review covers the RTB Phase II years of 2017 to 2019 to identify lessons for future research modalities and provide information on quality of science and effectiveness by answering the following questions:

  • To what extent does the CRP deliver quality of science?
  • What outputs and outcomes have been achieved, and what is the importance of those identified results?
  • To what extent is the CRP positioned to be effective in the future, seen from the perspectives of scientists and of the end users of agricultural research?
  • What is the added value of RTB as compared with the counterfactual?
