The study evaluated capacity for extension workers’ outreach to crop farmers on climate change resilience and adaptation in Edo State, Nigeria. The study specifically described socio-economic characteristics of the extension workers; described capacities for outreach by the extension workers; identified constraints to building capacities for outreach by the extension agents and identified strategies to building capacities of the extension workers.
