But access to affordable food is improving as both world food production and incomes rise
Of a global population totaling approximately 7 billion, about one in seven people are undernourished for at least part of every year.
While the world’s farmers produce enough calories to feed everyone on earth, access to food is uneven. The principal cause is extreme poverty.
But there are reasons to be optimistic about global food security. Incomes are improving, even among the most impoverished. In addition, global food production is increasing thanks primarily to yield improvements and farmers’ response to increased demand.
