Characterisation and stratification of legume

producers and production systems in Ethiopia

N2Africa Ethiopia Launch Workshop27-28 February 2014

Phase 1 Mid-term Review: Key Questions for N2Africa

How to embed G x E x M within market and institutional context?

How to understand best fit without understanding farmer adoption?


How to embed G x E x M within market and institutional context?

Develop a conceptual framework to expand G x E x M

Conceptual framework for scaling-outN2Africa

(GL x GR) x E x MSU Marketing for sale and

utilisation of the legume crop

D1 Delivery / availability of

legume genotypes

D2 Delivery / availability of

strains of rhizobium

D4 Delivery / knowledge of management

practices

D3 Delivery / availability of other inputs

How to understand best fit without understanding farmer adoption?

Review literature of adoption of legumes in Africa

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

High Agricultural Potential

Low Agricultural Potential

Good Market Access

High Population Density 1 2Low Population Density 3 4

Poor Market Access High Population Density 5 6Low Population Density 7 8

• 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
