In periurban Hyderabad, India, leafy vegetables are increasingly grown along the Musi River and sold in urban markets. This agricultural biodiversity can significantly help urban and periurban farmers become more resilient to the impacts of such changes.

This case study from Chakera village, Faisalabad City, Pakistan describes the transition from canal-water irrigation to wastewater irrigation over a period of several decades. It shows that while the initial motivation for wastewater use was water scarcity and a lack of choice, farmers soon realized there were benefits associated with this alternative water supply. In the subsequent decades, they made great efforts and overcame organizational, infrastructural and legal obstacles to establish wastewater irrigation as the only irrigation on most of the village’s agricultural area.

This article describes the conceptual advantages of including economic incentives in the basket of policy alternatives available for motivating improvements in water quality. With a particular focus on Asia, we discuss the incentives available for encouraging reductions in point and nonpoint source pollutants in urban, rural, and peri-urban settings. Several countries in Asia are implementing some form of economic incentives, either directly, in the form of effluent taxes or subsidies, or in combination with regulatory measures that help to ensure water quality standards are achieved. We also describe the importance of institutional capacity and political will in support of economic incentives, and the increasing usefulness of incentive programmes as economies develop and expand. The discussion includes several examples of programmes in China and Thailand, along with observations from India, Japan, Korea, and the Philippines.

Where wastewater is used without appropriate treatment, additional safety measures such as safer irrigation practices or careful vegetable washing are required to protect farmers and consumers. Implementing such food safety interventions in the informal farming sector is not easy, as they require behaviour change. Even where appropriate and low-cost interventions have been identified, low health risk awareness is a likely adoption barrier. Where this also concerns consumers, market demand for safer crops will be low and social marketing options have to be explored to support the desired behaviour change. Based on experiences from Ghana, where wastewater irrigation is an unplanned reality in and around all cities, the necessary steps and considerations for increasing the adoption probability are outlined under a generic framework which is based on social marketing, incentive systems, awareness creation/education and supporting regulations. Any of these approaches require accompanying research of the target groups and could gain in cost-effectiveness through a more integrated approach linking e.g. handwash and vegetable washing campaigns.

Urbanisation is increasingly affecting inter-sectoral water allocations. This paper looks beyond physical water transfers at the larger urban water footprint and how much it is affecting the urban periphery in the case of four cities in West Africa (Accra, Kumasi, Tamale and Ouagadougou). The results showed a water footprint variation between 892 and 1,280 m3/capita/year for these four cities based on actual and virtual water flows. The virtual flow through the food chain is outscoring actual domestic water consumption by a factor of 40–60 and using water resources far beyond the peri-urban interphase. However, the picture is changing with consideration of the grey water footprint. Due to limited wastewater treatment, peri-urban areas are the hot spots of water pollution diminishing their fresh water resources. The fresh water affected by the urban return flow easily doubles the overall urban water footprint. Improved on-site sanitation, especially with water saving and urine and excreta separating toilets would have a significant positive impact on the quality and quantity of the urban water footprint given that actual water availability is limiting large scale sewer connections for final wastewater treatment.

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.

A major challenge of urbanisation, for relevant decision makers, is the provision of sufficient food and water for the emerging mega-cities and appropriate peri-urban sanitation management. This paper focuses on the results of a project carried out by International Water Management Institute (IWMI) in three major cities in Ghana. The project was designed to provide decision support for nutrient recycling from organic waste in peri-urban areas, through waste composting or co-composting with nightsoil. Experiences of existing compost stations from Nigeria, Benin, Mali, Burkina Faso and Togo were taken into consideration to formulate the research framework. Apart from the technical aspect, the study looked at actual waste supply and its quality, a quantification of the compost demand as well as economic viability of different scenarios and legal implications. The analysis showed that from the city perspective cost savings are only possible if large volumes of waste can be composted to reduce waste transport costs while compost sale (and agricultural use) is not a necessity from the perspective of cost savings. In fact, despite much interest the farmers’ willingness to pay remained limited at the reservation price of US$5 per 50 kg bag. As this includes transport costs peri-urban areas will be those benefiting most from composting projects. Closing the rural-urban nutrient cycle appears unrealistic given the increasing transport distance; at least as long as smallholder farmers are targeted. However, the consideration of alternative customer segments and implementation of innovative business models could help in reaching different scales.
