According to a report from the United Nations Development Programme launched in Cape Town on 9 November 2006, "two in three people [in Kibera] identify the flying toilet as the primary mode of excreta disposal available to them."
[2] The UNDP report blames a taboo against bureaucrats and politicians discussing toilets,[3] while others see a reluctance among the Nairobi authorities to formalise what they characterise as an "illegal settlement".
[4] Such close contact leads to fears of diseases such as diarrhoea, skin disorders, typhoid fever and malaria.
[7] Several non-profit organisations have launched a "Stop Flying Toilets" campaign in Kenya, using a winged logo and sponsoring races with famous Kenyan marathon runners.
The public toilets, constructed by the non-governmental organisation Maji na Ufanisi, based in Nairobi, require a fee to use, but have been quite popular.
