Title: Agricultural Mechanization, Animal Traction, and Extensification and Intensification or Rice Farming: The Case of Tanzania


Agricultural machinery use is increasingly becoming common in Sub-Saharan Africa. Their potential benefits to smallholder farmers, however, remain unclear. This study aims to examine the impact of large- and small-scale agricultural mechanization on the expansion of the cultivated area (extensification), technology adoption and paddy yield (intensification), and labor productivity by using three-year panel data collected from rice farmers in Tanzania. In order to account for the endogeneity problem, we apply a multinomial endogenous treatment effect model to estimate the effects of mechanization. We also examine under what conditions mechanization occurs among small-scale farmers. We found that large four-wheeled tractor use contributes to the area expansion, while it does not affect land productivity. On the other hand, small two-wheeled power tiller use contributes to the increase in paddy yield and the expansion of area under rice cultivation at household level. Our results also show that agricultural mechanization occurs in the area with high population density growth and good access to the machinery.
