ABSTRACT

he study investigated the technical efficiency of cassava production under climate change in Nigeria, using primary data collected with structured questionnaire that were administered to 360 cassava farmers, selected through a multistage random sampling technique. Descriptive statistics and stochastic frontier production function were used in data analysis. Farm size and stem cuttings positively and significantly (p < 0.01) affected the output of the farmers, while that of labour was negative and significant (p < 0.05). The technical efficiency of the farmers was positively and significantly (p < 0.05) affected by age, education, delayed onset of rains, flooding of farms and improved stem cuttings, while the effects of farm size, and deforestation, land degradation and erosion on technical efficiency were negative and significant (p < 0.05). The average technical efficiency of the farmers was 53%, ranging from 39% to 88%. The paper advocated for policies that will check deforestation, land degradation and erosion, improve the quality of farmers’ age and education, and enhance their capacity to develop appropriate adaptations to climate change.
