Nigeria’s current rice and fish monoculture production system has yet to generate the desired profit. The integrated rice-fish farming system is a sustainable agricultural method that has the potential to enhance profitability. This study uses an endogenous switching regression model to assess the impact of the integrated rice-fish system on the profitability of farming households in Nigeria.
Data was gathered from 458 farmers participating in the USAID/FTF project in Nigeria. The findings revealed that the profit of the participating farmers using the integrated rice-fish technology increased by ₦156.00 per hectare, indicating a higher gross margin than non-participating farmers in the integrated rice-fish system. The results of the t-test analysis for the (ATT) and (ATU) of the participating farmers showed a statistically significant difference compared to the non-participating farmers at a 1% significance level. Transitional heterogeneity was observed to be positive for profitability, implying that both participating and non-participating farmers would be more likely to adopt the program in both regimes, given its profitability. The study recommends an input-supporting system for the farmers that could increase farm profits and the location of demonstration plots closer to the wards and wetlands to keep them informed and prepared for the system.
