The sub-Saharan Africa (SSA) situation especially in Nigeria is that many people cannot afford to buy enough food. This presentation therefore seeks to alleviate food insecurity in SSA, using Nigeria as case study, by deploying diverse models that could significantly improve agricultural productivity. The summarized model studies spanned over three decades (1993 – 2025). The technologies are: Accuracy of feel measured texture in Alfisol soil, quantitative and qualitative yield determinant techniques, the Global DALYs 136 countries Hidden Hunger Indices and Maps, Irrigation systems evaluation for off-season Olericulture, Integrated harvesting techniques for African eggplant (Solanum macrocarpon), FFM+ programme in Nigeria, Rapid-Sanitary and Phytosanitary Assessment Tool for Agronomists. These were discussed and way forward recommended. In conclusion, what is needed to alleviate food insecurity in Nigeria is commitment through leveraging agronomic technologies and engineering innovations to accelerate Africa's socio-economic transformation.
