used clothing is sold in more than 100 countries. in tanzania, used clothing is sold at the "mitumba" (swahili for "secondhand") markets. most of the clothing is imported from the united states. however, there are concerns that trade in secondhand clothing in african countries decreases development of local industries even as it creates employment in these countries. and the authors of "recycling of low grade clothing waste" warn that in the long run, as prices and quality of new clothing continue to decline, the demand for used clothing will also diminish.
