Belo Horizonte's successful food supply programs costs less than a nickel a day per person
"With a population of 2.5 million people...SMAAB’s budget has never been more than 2% of the overall city’s budget." (Rocha) "In 2008 Belo Horizonte’s total budget was R$5.1 billion." ("Informal Economy")
Calculation: 2% of 5.1 billion is R$102,000,000 per person that's 102,000,000/2,500,000=40.8 reals/person yearly per day that's 40.8/365=.112 reals/person daily in USD using the peak 2008 exchange rate of 2.4 reals/USD that's .112/2.4=.046
So that's less that a nickel a day.
