There is no evidence that rainforest farmers held systematic advantages over farmers in other African regions. Agricultural success across Africa has always depended on local environmental conditions, cultural innovation, crop portfolios, and historical contingencies—not biome alone.
| Region/Biome | Key Crops | Advantages | Challenges |
|---|---|---|---|
| Sahel/Savanna | Millet, sorghum, cowpea, cotton | Deep fertile soils (vertisols), seasonal pest break, storable grains | Unreliable rainfall, drought, sandy soils |
| Ethiopian Highlands | Teff, barley, wheat, coffee, enset | Volcanic soils, temperate crops, terracing tradition | Erosion, land fragmentation, frost risk |
| East African Rift | Banana, beans, maize, coffee, tea | Bimodal rain, volcanic soils, elevation diversity | Population pressure, disease, climate variability |
| Southern Africa | Maize, sorghum, cattle, wheat (winter) | Commercial infrastructure, research systems, irrigation | Rainfall variability, land tenure history |
