Conceptual framework for scaling-outN2Africa • Research design required that allows learning about D1, D2, D3, D4 and SU
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
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
Characterisation and stratification • Practical objective • Provides a structure of domains for sampling and testing • Selecting action sites for implementation and evaluation (e.g. baseline)
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
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
