Background: Retired Nigerian civil servants with disabilities may face intersecting financial and accessibility barriers, yet agriculture is often proposed as a supplementary livelihood activity. Objective: This critical integrative review examines the empirical and policy basis for disability-inclusive agricultural retirement strategies in Nigeria. Approach: Peer-reviewed evidence on public servants’ agricultural diversification in Kwara, Niger and Northeastern Nigeria is critically compared with disability-inclusive farming evidence from Northern Nigeria, Kenya and Ghana, and interpreted alongside livelihood and disability frameworks. Synthesis: Studies of public servants document enterprise participation and positive historical margins, while disability-focused studies identify constraints on labour participation and unequal access to productive technology. Ghanaian evidence suggests that technology gaps, rather than large technical-efficiency differences, contribute to production disparities. However, no included study directly estimates long-term agricultural livelihood effects among retired Nigerian civil servants with disabilities. Conclusion: Agriculture may offer an optional supplement to pension security when enterprises are individually selected, accessible, financially appraised and linked to support and markets. A testable policy framework and research agenda are proposed; causal effectiveness remains to be established.
