What do we mean by “food systems”?

The term includes every person and every process involved in
growing, raising or making food, right through to consuming
and what we do with our waste. This is from farmers to fruit
pickers to supermarket cashiers; from flourmills to refrigerated trucks
to neighbourhood composting facilities. Billions of people earn
their livings from the world’s food systems. In 2017, farming alone
accounted for 68% of rural income in Africa, and about half of rural
income in South Asia. Economists at the World Bank have estimated
that the global food system is worth roughly $US 8 trillion – about one
tenth of the entire world economy
