One in eight of the world's people goes hungry every day – that is 868 million people, more than the combined populations of the US, Canada and Europe – and here, courtesy of Oxfam's Food for All campaign to tackle global hunger, is the evidence on a plate.
These pictures feature families from around the world with their weekly food supplies. They range from Akavumu, Rwanda, where the Nyirazina family grows sweet potatoes, beans, sorghum grains and cassava shrubs to survive, and Vavuniya, Sri Lanka, where the Kumarapar family prepares meals of vegetables, rice and chicken, to Tower Hamlets in east London, where the Kerrs receive non-perishable items by their local food bank.
Oxfam says there is deep injustice in the way food is grown and distributed. The world's poorest people spend 50-90 per cent of their income on food, compared with just 10-15 per cent in developed countries. The World Bank estimates that 44 million people fell below the poverty line in the second half of 2010 due to high food prices.
The campaign launch comes just after figures were published last week showing that up to half the world's food is being wasted. According to the Institution of Mechanical Engineers report Waste Not, Want Not, while about four billion metric tonnes of food is produced globally each year, 30-50 per cent (or 1.2-2 billion tonnes) of it "never reaches a human stomach".
And it's not just rich countries such as the UK and the US throwing good food away; it is also being wasted in poor countries in the developing world. The difference, says Oxfam, is that, while food languishes uneaten in fridges here, in developing countries it goes to waste because of poor harvesting, storage and transport. In Vietnam, for example, a staggering 80 per cent of rice is lost between the field and the table.
The UN's Millennium Development Goals aimed to halve the levels of hunger found in 1990. To achieve this, the number of chronically undernourished people needs to be cut by 40 per cent to 500 million by 2015.
"The world produces more than enough food to feed everyone," says Kate Raworth, senior policy researcher for Oxfam. "Meeting the calorie needs of every person living with hunger would take less than 3 per cent of today's global food supply."
