  2. Phase 1 Mid-term Review: Key Questions for N2Africa

  3. Phase 1 Mid-term Review: Key Questions for N2Africa

  4. Conceptual framework for scaling-outN2Africa D4 Delivery / knowledge of management practices D1Delivery / availability of legume genotypes SU Marketing for sale and utilisation of the legume crop (GL x GR) x E x M D2 Delivery / availability of strains of rhizobium D3 Delivery / availability of other inputs

  5. SU Marketing for sale and utilisation of the legume crop (GL x GR) x E x M D2Delivery / availability of strains of rhizobium D3Delivery / availability of other inputs D1Delivery / availability of legume genotypes D4Delivery / knowledge of management practices

  6. Conceptual framework for scaling-outN2Africa • Research design required that allows learning about D1, D2, D3, D4 and SU

  7. Phase 1 Mid-term Review: Key Questions for N2Africa

  8. Review of constraints to adoption – methodology • 318 papers screened • 52 papers reviewed in detail • Bias to studies in Africa • Some non-legume studies included (e.g. agroforestry, CA, upland rice) • Constraints recorded • Frameworks for conceptualising constraints analysed

  9. Review of constraints to adoption – effect on research design and site selection • Test different treatments, delivery and dissemination and marketing mechanisms which can be influenced • Stratify those constraints that cannot be controlled but which will have an effect on the ‘fit’ • Monitor constraints which are dynamic, difficult to predict and therefore difficult to stratify or test

  10. Characterisation and stratification • Practical objective • Provides a structure of domains for sampling and testing • Selecting action sites for implementation and evaluation (e.g. baseline)

  11. Characterisation and stratification • Definition of variables, indicators and spatial units for each strata • Biophysical relevance of technology • Land availability, quality or tenure • Output market for agricultural (legume) products

  12. Ethiopia – adoption domains • Biophysical relevance of technology – low and high potential • Land availability, quality or tenure – low and high population density • Output market for agricultural (legume) products – good and poor physical access to markets

  13. N2Africa Target Districts in Ethiopia ‘Best bet’ grain legume crops defined in the bridging grant phase of N2Africa for Target Areas

  14. Stratify by key factors Factors: Agro-ecological Zone, Market Access, Population density Stratification Adoption domains

  15. Adoption Domains - chickpea

  16. Ethiopia – sites within adoption domains

  17. Probability pH < 5
