What are development domains?
Geographical locations sharing broadly similar rural development
constraints and opportunities
Why use development domains?
Geography matters
Allows targeting of interventions where they have a good chance of
success
All size fits all strategy for rural development in a large and diverse
country like Nigeria doesn’t work
A flexible approach that can be tailored according to development
needs and interests
