摘要

Jua Kali are Kiswahili words, which mean hot sun. They are commonly used to refer to small-scale enterprises operating on street pavements, open-air markets, undeveloped plots or market stalls. They manufacture goods like metal boxes, pots, bicycle parts and jikos (cooking stoves) at affordable prices by low-earning individuals. Since 1972, the sector has grown tremendously, providing employment opportunities to millions of Kenyans.
