The global food system is broken, leaving billions of people either underfed or overweight and driving the planet towards climate catastrophe, according to 130 national academies of science and medicine across the world.
Providing a healthy, affordable, and environmentally friendly diet for all people will require a radical transformation of the system, says the report by the InterAcademy Partnership (IAP). This will depend on better farming methods, wealthy nations consuming less meat and countries valuing food which is nutritious rather than cheap.
The report, which was peer reviewed and took three years to compile, sets out the scale of the problems as well as evidence-driven solutions.
The global food system is responsible for a third of all greenhouse gas emissions, which is more than all emissions from transport, heating, lighting and air conditioning combined. The global warming this is causing is now damaging food production through extreme weather events such as floods and droughts.
The food system also fails to properly nourish billions of people. More than 820 million people went hungry last year, according to the UN Food and Agriculture Organisation, while a third of all people did not get enough vitamins. At the same time, 600 million people were classed as obese and 2 billion overweight, with serious consequences for their health. On top of this, more than 1bn tonnes of food is wasted every year, a third of the total produced. Read more
