The number of hungry people worldwide continues to rise, according to the latest UN report on the State of Food Security and Nutrition in the World.

The joint report by UN agencies gauges whether the Sustainable Development Goal of Zero Hunger remains achievable.

Speaking on the need to improve not only the food production system, but also the efficiency of global resources to support it, the Food and Agriculture Organization’s (FAO) Assistant Director General and Chief Economist Maximo Torero, said in an interview that more than three billion people still “can’t even afford the cheapest healthy diet”.

Mr. Torero spoke to FAO’s Charlotta Lomas.
