Determinants of purchasing indigenous fruits and vegetables in Niger and Burkina Faso

Abstract

Food security in Sahelian countries is increasingly threatened by climate variability, rapid population growth, and dependence on monoculture staples. Indigenous Fruits and Vegetables (IFVs) are underutilized resources with potential to improve nutrition and resilience. This study examines IFV consumption patterns in Burkina Faso and Niger, focusing on nutritional benefits and socio-demographic determinants. Structured surveys were conducted with 458 respondents across both countries. Data were analyzed using descriptive statistics and the Heckman two-stage model to assess consumption and expenditure patterns, while correcting for sample selection bias. IFV consumption was associated with greater dietary diversity among households. Average expenditures were higher in Burkina Faso (3,904 CFA) compared to Niger (1,961 CFA). Gender, education, and religion significantly influenced consumption, while occupation and consumer characteristics affected expenditure levels. Nutritional knowledge was a major driver in Burkina Faso (76.6% of respondents) but less so in Niger (23.4%).Findings highlight IFVs as valuable contributors to nutrition and food security in the Sahel, though disparities in knowledge and socio-demographic factors limit utilization. Strengthening market infrastructure, promoting nutritional awareness, and adopting culturally sensitive, gender-inclusive policies are recommended to increase equitable access and maximize IFV potential.
