Abstract: Farm-level adoption of a portfolio of climate-smart agricultural (CSA) practices remains important to climate change adaptation and agricultural development in Sub-Saharan Africa. This paper uses nationally representative panel data sets in rural Nigeria to understand farm households’ decisions on choices of a range of CSA practices – such as cropping system diversification, improved seeds, and inorganic and organic fertilizers – and assess their combined effect on net farm returns using an endogenous switching treatment effects method. Our results reveal that adoption of CSA practices differs according to the level of asset ownership and incidence of shocks. While adoption of an individual CSA practice increases income compared with non-adoption, the highest farm income was achieved when farmers adopted all practices jointly. We conclude that adoption of multiple CSA practices can enhance farm income.
