Indian economist Amartya Sen, who won the Nobel Prize in 1998 for his work in welfare economics, argued that famine wasn’t caused by a lack of availability, but because people didn’t have the money and, importantly, the power to access food that had been produced.⁶ Africa is a good example: Since 2000, hunger in Africa—proxied by the prevalence of undernourishment—has increased by 25.8% despite the fact that food production has simultaneously increased by 8.6% per person.⁷
