Climate change and business activities: a case of cassava farmers in Ogun state, Nigeria.

Abstract

Climate change is an observable variation in the climate systems that are attributable to human (anthropogenic) activities and natural process (biogeographical), which alters the atmospheric composition of the earth and ultimately leads to global warming. The relationship between climate change (measured by increasing temperature trend and decreasing rainfall trend) and the business activities of cassava farmers in Ogun State, Nigeria appears not to have been fully examined; this study examines the relationship between climate change and the business activities of Cassava farmers in Ogun State. This study employs survey research design, through the administration of structured questionnaire to cassava farmers in Ijebu-Igbo, Ogun State. The research instrument (questionnaire) was validated using content validity index, through the assessment of five academics staff (in the departments of business administration and agriculture) at Olabisi Onabanjo University, Ago-Iwoye and Ibogun Campus, Ogun state, while the reliability of the instrument was tested through test-retest method by conducting a pilot study. The instrument was administered twice within an interval of two weeks and the outcome of the first pilot study was correlated with that of the second and a Cronbach alpha of 0.79 was obtained, which indicated that the instrument is reliable. The regression model was tested using categorical regression with the aid of STATA version 14. The findings revealed that climate change is negatively related to the business activities of cassava farmers in Ogun State with coefficient and probability value of: increasing temperature trend (-0.54, p-value<0.05) and decreasing rainfall trend (-0.72, p-value<0.05). It can therefore be concluded that increasing temperature trend and decreasing rainfall trend, have an inverse relationship with the business activities of cassava farmers in Ogun State, Nigeria. It is recommended that the government should come up with eco-friendly policies as well as liaising with other nations to combat global warming as well as creating irrigational facilities to augment decreasing rainfall, cassava farmers should maximize the use of the raining season as well as creating small irrigational facilities.

Climate Change Impacts and Adaptation Strategies of Cassava Farmers in Ebonyi State, Nigeria

“…Once more, 97.4% of the producers used fertilizers in the right amounts. It should be emphasized that increasing cassava yield in this period of climate change has been successfully accomplished by applying both organic and inorganic fertilizers (Paul et al, 2019). Again, 97.4% of the cassava farmers adopted efficient and effective use of insecticides.…”

“…Less rainfall shrivels cassava tubers that are growing in the soil, causing deterioration and a decrease in size and market value. Rainfall increases spawn a variety of pests and diseases that heavily consume cassava leaves, lowering the photosynthetic activity of cassava plants (Paul et al, 2019). It is reported that Nigeria's cassava crop would continue to decrease as long as climate change persists (Anarah et al, 2019).…”
