Using data collected from 250 yam based farming households in the Edo state, Nigeria, the study demonstrated the quantitative assessment of yam based farmers’ perception on climate change. Farmers' perceptions on three important climatic variables in agricultural production (temperature, rainfall and wind intensity) were quantified using a quasi-arbitrary ordinal weighting system. The results revealed first demand indices for temperature, rainfall and wind intensity as 0.87, 0.38 and 0.84 respectively while the first supply indices for temperature, rainfall and wind intensity were 0.27, 0.22 and 0.14 respectively. The study indicated significant increase and decrease in temperature and rainfall respectively. The study also affirmed that climate change contributed significantly to reduction in yam production in the study area. The study recommends the need for programmes geared towards providing farmers with effective adaptation strategies which would help provide a buffer against adverse climatic conditions. |
