Abstract

Malawi's agricultural sector, dominated by poor smallholder household farmers, faces numerous challenges. Farmers usually have limited wealth, and the sector is characterized by low productivity. This study investigates how wealth hinders or supports productivity growth. The study employs a mixed-method approach that combines a systematic literature review and Bayesian moderation and mediation regression analysis. The study reveals a complex relationship, with findings indicating a negative correlation between wealth and productivity growth. This is attributed to the implementation of subsidized fertilizer program benefiting the majority of poor farming households. Further analysis revealed a more complex relationship. Specifically, wealth has a positive indirect effect on productivity through distance from district centers yet has a negative indirect effect on agricultural markets. These findings highlight the need to improve the provision of services in district centers, enhance market functionality, and address spatial disparities to optimize productivity. Initiatives such as promoting digital platforms, modernizing extension services, improving financing, and ensuring demographic management should be employed to address systemic constraints. Together, such initiatives would foster an enabling environment that supports small-scale farmers to adopt productive and commercial farming practices that drive wealth and productivity. The study's findings have significant implications not only for agricultural development policies in Malawi but also for similar agricultural development contexts.
