As urbanisation increases, so does the challenge of meeting water, sanitation and food requirements in urban areas. In particular, the management of human excreta from on-site sanitation facilities remains a challenge and continues to endanger public health and degrades the environment through soil and water pollution. Yet much of the excreta consist of organic matter and nutrients that are valuable inputs for agriculture. Recycling in agriculture has often neglected the recovery of nutrients and organic matter in faecal sludge collected from on-site sanitation facilities in developing countries. Exploring the high proportion of resources in excreta can provide a win–win strategy by reducing the environmental pollution, enhancing soil fertility and therefore improving livelihoods. Challenges to maximising these benefits include: type of sanitation facility used in developing countries, nature of faecal materials, prevailing treatment technologies which are usually designed for waste disposal not for reuse, institutional and market factors as well as negative perceptions regarding excreta use in agriculture. Nevertheless, urban and peri-urban agriculture presents a good opportunity for nutrient recycling, provided that technological and socio-economic strategies for optimum recovery are taken into account. The paper concludes with a description of successful recycling options that can contribute to improving farm productivity, using evidence from Ghana.

Growing cities and their demand for water challenges the management of water resources and provides opportunities for wastewater use in irrigated agriculture. In the cases studied, large volumes of fresh water are extracted from sources often located increasingly further away from the city, while investments in wastewater disposal often lag behind. The resulting environmental impact in peri-urban areas can have multiple consequences for public health, in particular through the use of untreated or poorly treated wastewater in irrigated agriculture. Despite significant efforts to increase wastewater treatment, substantial volumes of untreated wastewater are applied in irrigated agriculture in Addis Ababa (Ethiopia), Accra (Ghana) and Hyderabad (India). Additional options for safeguarding public health are required to allow the cities to maintain the benefits from already existing, but largely informal, wastewater reuse.
