In the traditional operation of production-consumption groups in rural areas of Senegal, the group chief, or Borom njël, has a social duty to make sure family food needs are met. His ability to do this is supported by certain social rules governing these groups, and by a favourable environment. However, various changes have now adversely affected the environment. These changes prompted us to assess the Borom njël’s current ability to go on playing his social rule as a food provider. From data collected in two villages of the Senegalese Groundnut Basin, using multivariate analysis, we identified three production-consumption group profiles according to how the Borom njël ensured main cereal supplies: (i°) market purchase with migrants’ remittances; (ii°) home production and (iii°) market purchase with own resources. The ability of the Borom njël to ensure cereal supplies differed according to the profile. We used a multivariate logit model to study the determinants affecting the Borom njël’s ability to ensure cereal supplies for the production-consumption group. We found that physical assets and wage labour employment increased this ability. We also found that agricultural income, including livestock, was positively correlated to the likelihood of the Borom njël successfully ensuring cereal supplies, particularly those depending heavily on own production. Additional income earned by the Borom njël from non-agricultural activity had the same positive effect, particularly when ensuring cereals provision through market purchase. We end with some thoughts on the increasing reliance of Borom njëls on migrants’ remittances to ensure that family cereal needs are met.
