An urgent challenge this 21st century is ending hunger and malnutrition in sub-Saharan Africa (SSA) by 2030. Agricultural productivity is very low in SSA, which has the highest population growth rate globally, and is challenged by a myriad of problems including deteriorating soils, increasing pest and disease problems, drought, exacerbated by climate change. Extensive research reports indicate that productivity of the staple crops of SSA would need to be increased by 80% by 2050 to feed a burgeoning population.
