“…Increasing levels of sewage sludge have been identified in many studies that increase soil organic matter content. Wastewater treatment sludge can be used to solve organic matter deficiencies, especially due to the high organic matter content [29]. In addition, the mineralization of the more easily degradable forms of sludge organic matter by soil microorganism is rapid, depending upon soil conditions [30].…”

“…The use of organic wastes for soil amendment is becoming one of the most sustainable approaches to manage the large quantity of surplus that are being generated as well as to overcome the shortage of nutrients for crop growth, especially phosphorous [1] , [2] , [3] . Vinasse, which originates from the production of ethanol fuel from sugarcane, has been widely used as soil amendment in sugarcane crops in Brazil.…”

“…Recycling happens when people save and transfer reusable items to places where they can be re-created into either similar or new products than throwing them away. Composting is also a method of recycling that mimics nature's recycling of nutrients and encompasses using decomposer microbes to reprocess yard trimmings, vegetable food scraps, as well as other biodegradable organic wastes [12]. The organic material produced is then added to the soil to fertilise the soil to improve crop yields.…”

“…Additionally, this technique requires proper landfills for their inert by-products, a factor that increases the cost of the incinerator [14,15]. Disposal denotes to the throwing away of waste, commonly to landfill sites, and poses a great threat to the environment [12]. In SSA countries, current disposal practices such as open dumps, open pits, streams and drainage channels result in human health and environmental problems [16].…”

Waste management has become pertinent in urban regions, along with rapid population growth. The current ways of managing waste, such as refuse collection and recycling, are failing to minimise waste in cities. With urban populations growing worldwide, there is the challenge of increased pressure to import food from rural areas. Urban agriculture not only presents an opportunity to explore other means of sustainable food production, but for managing organic waste in cities. However, this opportunity is not taken advantage of. Besides, there is a challenge of mixed reactions from urban planners and policymakers concerning the challenges and benefits presented by using organic waste in urban agriculture. The current paper explores the perceived challenges and opportunities for organic waste utilisation and management through urban agriculture in the Durban South Basin in eThekwini Municipality in KwaZulu-Natal (KZN) Province of South Africa. It is anticipated that this information will be of use to the eThekwini Municipality, policymakers, researchers, urban agriculture initiatives, households and relevant stakeholders in the study areas and similar contexts globally. Two hundred (200) households involved in any urban farming activity and ten (10) key informants (six (6) staff from the Cleaning and Solid Waste Unit of the eThekwini Municipality and four (4) from the urban agricultural initiative) were selected using convenient sampling. Descriptive statistics and inductive thematic analysis were used to analyse data. The significant perceived challenges and risks associated with the utilisation of organic waste through urban agriculture included lack of a supporting policy, climatic variation, lack of land tenure rights, soil contamination and food safety concerns. Qualitative data further showed that the difficulty in segregating waste, water scarcity, difficulty in accessing inputs, limited transportation of organic waste, inadequate handling and treatment of organic waste, and being a health hazard were some important challenges. On the other hand, the significant perceived benefits associated with the utilisation of organic waste through urban agriculture were enhanced food and nutrition security, and opportunities for business incubation. Other important benefits established through qualitative data were an improved market expansion for farmers and improved productivity. Overall, despite the perceived challenges and risks, there is an opportunity to manage organic waste through urban agriculture. It is imperative for an integrated policy encompassing the food, climate and waste management to be developed to support this strategy. All stakeholders—the government, municipal authorities and urban agricultural initiatives should also, guided by the policy, support urban farmers, for example, through pieces of training on how to properly manage and recycle organic waste, land distribution, inputs availability and water usage rights among other things.
