Lubumbashi is the second largest city of the Democratic Republic of the Congo. Since 2000, its population has expanded by more than 50% to at least 1.5 million. Keeping pace with the city's growth, an FAO project has created a flourishing urban and peri-urban horticulture (UPH) sector. The area under horticulture has risen from less than 100 ha to 725 ha. Market gardens ringing the city produce more than 60 000 tonnes of vegetables a year.
