Abstract

This study employed Feasible Generalised least square and structural Ricardian models to investigate the impact of climate change on yield and net revenue of cassava production across the six across the six geopolitical zones in Nigeria using 1200 farming households. The data on climate variables (rainfall and temperature used for the study were obtained by the Nigeria meteorological agency while the data on cassava farmers characteristics and farm level characteristics was obtained from General Household Survey wave 4 data. The results showed that climate variables had varying impact on the yields and net revenue of cassava agriculture. Yield increases as temperature increases and reduces as rainfall increases, the net revenue increases as rainfall increases and reduces as temperature increases. The marginal effect of climate change showed that cassava is more sensitive to the infinitesimal change in climate.  The predicted climate scenarios showed that extreme climate condition will be dangerous to cassava and it will reduce the net revenue generated from cassava production.

Key words: Climate change, Net revenue, Yield, Ricardian, FGLS, Cassava
