Abstract – Weathering shocks: the effects of weather shocks on farm input use in sub-Saharan Africa

The main objective of this study was to provide evidence on the impact of weather shocks on the intensity of farm input use by smallholder farmers in Africa. Specifically, this paper addresses the question: how do weather shocks affect the intensity of farm input use and land productivity in Sub-Saharan Africa? Given the importance of rainfall and temperature on-farm yield, any shock in weather patterns would eventually affect farmers’ expectations of farm yield. I explore the relationship between weather shocks and the intensity of inputs use at the plot level based on national large-scale panel data from three African countries (Niger, Nigeria, and Tanzania). By combining monthly drought index data (Standardized Precipitation-Evapotranspiration Index (SPEI)) with rich Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) dataset,

I find that the intensity of chemical fertilizers strongly reduces more in drought areas than less-prone drought areas during growing seasons. I also find that the drought during lean seasons is associated with higher pesticide uptakes. From these results, the suggestive evidence shows that drought weather induces the farmers to reduce purposively farm investments, including yield-enhancing technology like chemical fertilizer, hence worsening adverse farm yield implications.
