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 atlas provides information on the salient findings of the project entitled "Ensuring Health and Food Safety from Rapidly Expanding Wastewater Irrigation in South Asia" coordinated by the International Water Management Institute (Hyderabad office). The three year project funded by the German Federal Ministry of Economic Cooperation and Development (Bundesministerium für Wirtschaftliche Zusammenarbeit und Entwicklung - BMZ) was carried out in two countries, India and Pakistan, in collaboration with a number of international and local partners. This atlas highlights the findings from India. The atlas comprises thematic maps and their corresponding descriptions highlighting the key findings of the project. The wastewater use in agriculture described here is associated with a polluted riverine system, due to all types of city discharges. As such, it can be expected that the water quality can change considerably in different stretches of the 40 km stretch of the river, with the head end being more polluted than the tail end. Therefore in order to avoid a rigid classification, the descriptions to the maps refer to the term "(Musi) river water". In the rest of text, the term "wastewater" is used in the context of the chemical and biological attributes associated with agronomic and health risks in any given stretch of the river. The atlas was prepared as a summary document of the key findings of the project, to promote a discussion on the wastewater use in agriculture, at the dissemination workshop held in October 2008.

In 2006 a comprehensive sampling program was undertaken in two pre-selected peri-urban villages in Faisalabad, Pakistan to evaluate the soil and agronomic impacts of long-term (25–30 years) untreated wastewater re-use on wheat grain and straw yields and attributes of wheat straw fodder quality. Soil SAR, ESP, RSC and ECe were 63%, 37%, 31%, and 50% higher under wastewater (WW) as compared with canal water (CW) irrigated plots. Further, 2.7 and 6.65 fold increases in soil NO3- + NO2 - - N and Olsen-P were observed in WW as compared with CW irrigated plots. However, no significant differences in grain yield, wheat straw biomass, or fodder quality attributes were observed between WW and CW irrigated plots. In addition, for both CW and WW irrigated plots wheat straw, Cd and Pb concentrations were orders of magnitude below the EC Maximum permissible levels for Pb and Cd in feed materials and thus pose no threat to the fodderlivestock food chain. Further, elevated soil N associated with WW irrigated plots has a significant (p<0.01) positive influence on fodder quality by increasing the N content. Factorial ANOVA with covariance indicates that effective management of the elevated soil ECe in WW irrigated plots would increase grain yield and wheat straw biomass by 853 kg ha-1 (19.5%) and 819 kg ha-1 (18.6%) respectively as compared with CW irrigated plots. In Faisalabad, if managed appropriately to address emerging salinity issues the contribution of wastewater irrigation to the achievement of MDGs 1 and 7 could be significant if adverse impacts remain as marginal as found in this study.

Water scarcity is one of the most pressing problems for many arid and semi-arid regions. With regard to the need for a more efficient and sustainable use of the existing freshwater resources, one main focus should be on agriculture with its share of 80-90% of the global water consumption (UNEP and GEC 2004). The Indus Basin Irrigation System in Pakistan is the largest irrigation system in the world and the backbone of the country’s economy (ALAM et al. 2007). However, because of an increasing demand for irrigation water and a lack of maintenance of irrigation infrastructure resulting in water losses, many farmers can no longer satisfy their irrigation water requirements with canal water. Beside the use of groundwater, another coping strategy is the use of wastewater for irrigation. This practice is not confined to Pakistan: worldwide, an estimated 200 million farmers irrigate 20 million hectares of land with wastewater (Raschid-Sally and Jayakody 2008). Among scientists and decision makers, a negative perception of wastewater irrigation prevails (CARR et al. 2004). Beside concerns about negative impacts on health and environment, various scholars have stated that wastewater irrigated agriculture might not be sustainable in the long term (PESCOD 1992, CHANG et al. 2002, ENSINK 2006). This study, which was part of a larger research project on wastewater irrigation (AMERASINGHE et al. 2009, WECKENBROCK et al. 2009), focuses on one aspect of agricultural sustainability: economic longterm impacts of wastewater irrigation in a periurban area of Faisalabad, Pakistan. In terms of inputs, the costs of irrigation water for groundwater and wastewater users are compared. In terms of outputs, the comparison is between the economic outputs of agriculture per area of the two groups.

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.
