<P> The 2011 SIK study estimated the total of global food loss and waste to around one third of the edible parts of food produced for human consumption, amounting to about 1.3 billion tonnes (1.28 × 10 long tons; 1.43 × 10 short tons) per year . As the following table shows, industrialized and developing countries differ substantially . In developing countries, it is estimated that 400--500 calories per day per person are going to waste, while in developed countries 1,500 calories per day per person are wasted . In the former, more than 40% of losses occur at the postharvest and processing stages, while in the latter, more than 40% of losses occur at the retail and consumer levels . The total food waste by consumers in industrialized countries (222 million tonnes or 218,000,000 long tons or 245,000,000 short tons) is almost equal to the entire food production in sub-Saharan Africa (230 million tonnes or 226,000,000 long tons or 254,000,000 short tons). </P> <Table> <Tr> <Th> Food loss and waste per person per year </Th> <Th> Total </Th> <Th> At the production and retail stages </Th> <Th> By consumers </Th> </Tr> <Tr> <Td> Europe </Td> <Td> 280 kg (617 lb) </Td> <Td> 190 kg (419 lb) </Td> <Td> 90 kg (198 lb) </Td> </Tr> <Tr> <Td> North America and Oceania </Td> <Td> 295 kg (650 lb) </Td> <Td> 185 kg (408 lb) </Td> <Td> 110 kg (243 lb) </Td> </Tr> <Tr> <Td> Industrialized Asia </Td> <Td> 240 kg (529 lb) </Td> <Td> 160 kg (353 lb) </Td> <Td> 80 kg (176 lb) </Td> </Tr> <Tr> <Td> sub-Saharan Africa </Td> <Td> 160 kg (353 lb) </Td> <Td> 155 kg (342 lb) </Td> <Td> 5 kg (11 lb) </Td> </Tr> <Tr> <Td> North Africa, West and Central Asia </Td> <Td> 215 kg (474 lb) </Td> <Td> 180 kg (397 lb) </Td> <Td> 35 kg (77 lb) </Td> </Tr> <Tr> <Td> South and Southeast Asia </Td> <Td> 125 kg (276 lb) </Td> <Td> 110 kg (243 lb) </Td> <Td> 15 kg (33 lb) </Td> </Tr> <Tr> <Td> Latin America </Td> <Td> 225 kg (496 lb) </Td> <Td> 200 kg (441 lb) </Td> <Td> 25 kg (55 lb) </Td> </Tr> </Table> <Tr> <Th> Food loss and waste per person per year </Th> <Th> Total </Th> <Th> At the production and retail stages </Th> <Th> By consumers </Th> </Tr> <Tr> <Td> Europe </Td> <Td> 280 kg (617 lb) </Td> <Td> 190 kg (419 lb) </Td> <Td> 90 kg (198 lb) </Td> </Tr>
