Reinvestment Ventures as a Pathway to Sustainable Livelihoods for Small-Scale Maize Farmers in Kondoa District, Tanzania

Abstract

Small-scale maize farmers often need to make one harvest serve several purposes: food, school costs,
farm inputs, and capital for another livelihood activity. This study examined whether reinvesting
maize-sale income in other crops, horticulture, livestock, and small businesses was associated with
more sustainable livelihoods among farmers in four wards of Kondoa District, Tanzania. A crosssectional mixed-methods design combined a household survey of 406 farmers with focus-group and
key-informant evidence collected in 2022. Descriptive statistics established the prevalence of
reinvestment, Cronbach’s alpha assessed the internal consistency of two livelihood-outcome indices,
chi-square tests examined ward differences, and ordinary least-squares models with HC3 robust
standard errors estimated adjusted associations. Half of respondents reported using maize income to
support other crops (50.5%), 45.2% horticulture, 51.0% livestock, and 40.5% a small business. The
asset-improvement and social-well-being indices showed good internal consistency (α=.777 and
.815). Crop reinvestment was positively associated with asset improvement (B=.166, p<.001) and
social well-being (B=.123, p<.001). Livestock (B=.106, p=.005) and small-business reinvestment
(B=.092, p=.003) were also associated with social well-being. Among respondents with complete
income data, small-business reinvestment was associated with 40.6% higher income from other
livelihood activities (B=.341, p=.039), controlling for maize income and household characteristics.
Focus-group accounts helped explain these patterns: farmers described diversification as a practical
response to unreliable maize markets and as a way to meet everyday household needs. Because the
evidence is cross-sectional and self-reported, the findings indicate association rather than causation.
Strengthening market access, financial capability, and context-specific advisory services may help
farmers convert maize earnings into more resilient livelihood portfolios.
