Intensity of commercialization and the dimensions of food security: the case of smallholder farmers in rural Tanzania

摘要

Purpose - Transformation of smallholder agriculture from subsistence to more commercially-oriented production is one of the strategies advocated for improving rural households’ food security and general welfare. The purpose of this paper is to assesspotential differential effects of smallholder commercialization intensity on the different dimensions of food security. Design/methodology/approach - Using household data from rural Tanzania, the study employed Tobit regression and Generalized Propensity Score (GPS) approaches to analyze smallholder commercialization intensity and associated food security effects. Findings - Results show that smallholder commercialization has heterogeneous effects on the different dimensions of food security. Specifically, lower levels of commercialization are associated with lower food availability, access, utilization and stability. At higher intensities of commercialization, smallholders have higher food availability and access but modest improvements in food utilization and stability. Findings suggests that heterogeneous effects of commercialization on food security and the multi-dimensional nature of food security are important aspects to consider in the design of strategies to improve smallholder agriculture for enhanced food security and welfare. Research limitations/implications - It is important to point out that while food security is still a complex phenomenon, one that cannot be analyzed easily, so is commercialization. This study has used only one of the many definitions of commercialization. Originality/value - Most existing literature on smallholder commercialization groups farmers into commercial and subsistence-oriented households. However, smallholders commercialize at various levels of intensity.This paper, conversely, analyzes the potential effects of different levels of commercialization on the various aspects of food security. Further, unlike extensive literature that focus on a narrow definition of food security, this paper expands the evidence of the implications of smallholder commercialization on the different dimensions of food security namely, food availability, access, utilization and stability.
