Analysis of Cassava Farmers’ Response to Climate Change Adaptation: Implication for Sustainable Food Production in Nigeria
Main Article Content
The study examined how smallholder cassava farmers responded to changes in climate by identifying adaptation strategies adopted by the farmers and its determinants. In addition, the study analyzed the trend of production, productivity, and hectarage of cassava in Nigeria from 1980-2017. Multinomial logit model and exponential trend equation were employed to analyze the obtained data. The cassava farmers studied adopted use of irrigation (10%), livestock ownership 53.24%), mixed cropping (79.86%) and use of improved crop variety (92.81%) as major adaptation methods. The adaptive approaches used by cassava farmers were determined by farming experience, level of education and ownership of transport. The empirical trend analysis revealed that the coefficients of cassava output and hectarage were - 45.15 and -43.42 respectively and statistically significant at 1% implying a decrease in cassava output and hectarage within the period under study. It was further revealed that the marginal effects for the level of education and ownership of a means of transport were 0.11 and – 0.12 respectively. The implication of this result is that one unit increase in level of education and ownership of means of transport of a cassava farmer is associated with 11% more likely and 12% less likely that the farmer will adopt livestock ownership as adaptation strategy over the use of new crop variety. Therefore, from the established result, it was suggested that educational campaign on climate adaptation strategies should be embarked on so as to hearten the consciousness of cassava farmers on adaption strategies to climate change. More so improved cassava varieties are required for sustainable cassava production and food security in Nigeria.
