Abstract: Background and Objective: Achieving food security is still a major problem for households in most rural areas of Nigeria. Hence, this study was conducted to ascertain the perceived causes of household food insecurity in six rural areas of Kano state where intensive crop farming is practiced by rural farmers. Materials and Method: Multistage sampling technique was used in selecting 120 respondents for the study. Descriptive statistics such as frequency, percentage and mean scores were used to analyze the data. Results: A greater percent of the households were engaged in food, cash crop production and animal rearing. Also, the major crops produced were cereals such as maize, sorghum and millet, among others. Though the majority of the respondents ate three times daily, but they consumed mostly carbohydrate containing foods such as rice, Tuwo shinkafa, cornflour, gero and yam, among others. The respondents indicated that their food security situation was worse off than the previous years. The respondents also indicated that perceived causes of their food insecurity were mainly, poor extension services, large family size and poverty. Conclusion: In spite of the agricultural production activities of the farmers, the study found out that farmers were increasingly food insecure. There is urgent need for policy makers in Kano state to implement pro-poor agricultural policies that would reduce farmers’ vulnerability to food insecurity. This has the potential to raise efficiency in food crop production and enhance farmers’ food security status.
