Dr Shamie Zingore, Director of Research and Development at the African Plant Nutrition Institute, delves into the relationship between soil health, crop productivity and human nutrition.
Africa is home to an estimated 33 million smallholder farmers who contribute about 70 per cent of the continent’s food supply. But these farmers face various constraints, such as low productivity and limited access to new agricultural technologies. The soils in sub-Saharan Africa (SSA) in particular are some of the poorest in the world due to naturally low fertility and insufficient soil conservation measures. It is estimated that the continent loses over US $4 billion worth of soil nutrients each year, severely eroding its ability to feed itself. Crops require an adequate and balanced supply of nutrients to produce good yields, yet currently, more than 60 per cent of SSA’s agricultural land faces challenges around crop production.
