Research on millet gene flows reveals social barriers to seed dissemination in the Lake Chad Basin

The thesis of Abdel Kader Naino Jika, defended at the University of Paris-Sud in 2016, highlights social barriers hindering the dissemination of millet genes in the Lake Chad Basin. This study reveals how the cultural diversity of farmers influences agricultural resilience in the face of current environmental and socio-economic challenges.

In a context of increased vulnerability of sub-Saharan agriculture, Abdel Kader Naino Jika's research explores the gene flows of millet (Pennisetum glaucum) in the Lake Chad Basin. The study emphasizes the importance of genetic diversity of crops, closely linked to the cultural practices of farmers, and highlights a social barrier that limits the exchange of varieties and knowledge.

The analysis of gene dissemination dynamics reveals that, although genetic introgressions occur between different populations, seed conservation practices rooted in cultural traditions restrict the adoption of new varieties. This research underscores the importance of an integrated approach to overcome these barriers and promote genetic diversity.

The results of this research offer opportunities to strengthen agricultural resilience in sub-Saharan Africa. Policymakers are encouraged to support initiatives that promote knowledge exchange and genetic diversity, while considering the cultural practices of farmers to improve food security in the region.

« « The genetic diversity of crops is closely linked to the socio-cultural diversity of farmers, which complicates the dissemination of millet genes in certain communities, » says Abdel Kader Naino Jika. »

« « This research highlights the importance of accessing knowledge about gene flows to inform strategic decisions regarding food security in West Africa, » emphasizes the Lektaris team. »
