Défis de la qualité des données pour l’analyse de l’abordabilité alimentaire dans les pays du Sahel central, en Afrique de l’Ouest

Abstract

Food and nutrition insecurity is a major concern for West African countries, especially in the Central Sahel region, which includes Burkina Faso, Mali and Niger. Analyzing access to healthy and nutritious food in that area requires high-quality data, and the inclusion of “food affordability,” in addition to traditional data, further increases this need for high-quality data. This study is based on a food affordability analysis model and uses metadata from the three countries to assess the quality of the available data. The results show persisting major deficiencies, particularly in agricultural, trade, and market data, which are often missing, inaccessible or incomplete. Although a satisfactory level of harmonization is achieved for some of the variables, disaggregation remains inadequate. The analysis shows that making data comparable and accessible is a challenge that needs to be tackled by setting up a common, structured data collection system for Central Sahel.
