Agronomic biofortification of crops to fight hidden hunger in sub-Saharan Africa

This article in the Global Food Security journal discusses the effectiveness of agronomic biofortification – the application of mineral micronutrient fertilizers to soils or plant leaves to increase micronutrient contents in edible parts of crops – and it’s potential to fight hidden hunger. There is evidence that agronomic biofortification can increase yields and the nutritional quality of staple crops, but there is a lack of direct evidence that this leads to improved human health. »

The impact of taxes and subsidies on crop yields: Agricultural price distortions in Africa

This report elaborates on the impact of agricultural taxes and subsidies on crop yields in Africa. The key finding presented is that both taxes and subsidies wield a negative influence on crop yields. Clearly, levying taxes and subsidies have their merit, for raising public finances and providing rural income support respectively, but neither leads to a more intensified agriculture. »

Origins of food crops connect countries worldwide

This research on the Royal Society shows how the origins of food plants has led to the recognition that specific geographical regions around the world have been of particular importance to the development of agricultural crops. Yet the relative contributions of these different regions in the context of current food systems have not been quantified. The authors determine the origins (‘primary regions of diversity’) of the crops comprising the food supplies and agricultural production of countries world. »
