ABSTRACT:

The study analyzed cost and returns and cost effectiveness of climate change adaptation strategies among smallholder crop farmers in Borno State, Nigeria. The study was conducted in Sudan savannah and Guinea savannah Agro-Ecological Zones (AEZ) of the State. Data for the study were obtained using structured questionnaire with the aid of oral interview schedule. Multi-stage sampling procedure was used in selecting360 smallholder farmers for the study. Both descriptive statistics (percentages; frequencies, means);inferential statistics (simple regression) and budgetary technique (gross margin) were used to analyze the data. Findings on the Gross Margin (GM) analysis indicated that application of chemical had the highest gross margin (N89, 880), this was followed by increased application of fertilizer (N88,015) and use of improved crop varieties tolerant to new climate regime (N81,626). Application of chemical had the least marginal cost (0.192), therefore, was the most cost-effective adaptation strategy. Result on the F-test of hypothesis revealed that null hypothesis was rejected and the alternative which states that there is significance difference between cost and returns of the component crops used in adaptation strategies to climate change was accepted. The study concludes that applications of chemical, increased application of fertilizer and use of improved crop varieties had the highest gross margin per hectare. Application of chemical had the least MC, therefore is the most cost-effective adaptation strategy. The study recommends among others that adaptation materials should be provided to farmers at subsidized rate. This will increase farmers’ capacity to adapt the most profitable and cost-effective adaptations options; and advocacy and awareness creation on the cost- effective climate change adaptation strategies should be carried out among farmers.
