An assessment of the viability and sustainability of the use of humanure for household agricultural purposes : a case study in Cottonlands, eThekwini Municipality.

Abstract

Many South Africans face problems relating to poor sanitation and inadequate nutrition. This is especially prevalent in the peri-urban and rural areas of the country. Whilst urban areas are provided with water borne sewage, the provision of this service to peri-urban and rural areas has been neglected due to topography, water issues, high cost and apartheid legacy. The use of sanitation facilities that allow for composting of faecal matter is a viable option, which, if properly managed, can address sanitation issues and food security by providing compost for household agriculture. The aim of this research is to gauge the perception of people in the Cottonlands community, located within the eThekwini Municipality, on the use of humanure for household agriculture; as well as to determine the safety of food crops grown with humanure. Questionnaires and microbiological testing was used to determine community perceptions and food safety, respectively. Acceptance levels of using humanure for household agriculture ranged from total to non-acceptance. Observation showed visible impact with the use of humanure with crops appearing to produce more fruit, and seeming healthier overall. Microbiological food safety tests indicated unsafe levels of bacteria and pathogens associated with food borne illness. Overall, it is recommended that further research and tests be conducted as there is a great potential from this study to improve the quality of life for many, as well as contribute to sustainable environmental practices.
