This study investigates the willingness to pay (WTP) for flood insurance among cassava-based farmers in the Ikwerre Local Government Area (LGA) of Rivers State, Nigeria. The area, prone to seasonal flooding, presents significant risks to agricultural productivity, particularly for cassava farming, a primary livelihood source. Using descriptive and binary logit regression models with the aid of questionnaires and interview schedules, data were collected from 64 cassava farmers randomly selected across different communities within the LGA. The results show the majority (68.7%) of the cassava-based farmers were female, with a mean age of 41.7 years, an educational level mean of 9.8 years, a mean household size of 6 members, and 16.1 years as the mean of farming experience. The majority (71.9%) of the cassava-based farmers were willing to pay for flood insurance. The Logit regression model result shows that educational level and farming experience were statistically significant at 1% and 5% respectively determining the willingness of cassava-based farmers to pay for flood insurance. The major constraints are lack of awareness, affordability, limited access to credit, and institutional barriers. The study recommendation policy includes designing inclusive agricultural insurance products that improve farmers’ resilience against climate-induced flooding, targeted subsidy programmes to make premiums more affordable, increased awareness campaigns on the benefits of flood insurance, and the introduction of flexible insurance schemes tailored to the needs and capacities of small-scale farmers. These measures could enhance adoption rates and contribute to more sustainable cassava farming in the flood-prone area.
