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.

Along the Musi River in periurban Hyderabad, leafy vegetables are increasingly grown and sold in urban markets. Wide areas are irrigated with river water, highly polluted by sewage and industrial wastewater. Previous studies showed that periurban agriculture in Hyderabad plays an important role for the livelihoods of a diverse group of people, many of whom are women, from different castes, religions and social classes. During a field study in 2007 (in cooperation with the International Water Management Institute and the University of Freiburg, Germany), a rapid appraisal of vegetables cultivated with wastewater irrigation was carried out. In order to estimate the risk from pathogens for consumers, the percentage of vegetables consumed raw was calculated. A large number of vegetable varieties were found in the vegetable gardens, also in those where wastewater was used for irrigation, contrary to expectations. The leafy vegetables - traditionally in high demand - have a short growing season and fetch high market prices due to their usage in traditional dishes. In 2008, the study was extended to explore the role of agricultural biodiversity for livelihoods and building resilience using the sustainable livelihoods approach as theoretical background. 54 varieties of vegetables from 20 families were identified. Among those, 18 were cultivated for the leaves most of which were usually cooked. There was no significant difference in biodiversity (Shannon-Index and Simpson-Index were calculated) between wastewater and groundwater irrigated fields, but a significant difference in the species composition (almost 95% leafy vegetables where wastewater was used, around 70% fruit bearing vegetables where groundwater was used for irrigation) for several reasons such as insecure land tenure, water and soil quality, risk mitigation and market demand. Previous studies show that the use of wastewater for irrigation can have both positive and negative effects on agriculture. Besides possible health risks, fertiliser costs could be saved due to the high nutrient content of the wastewater. Agricultural Biodiversity is thus not necessarily diminished by the use of wastewater and can contribute in many ways to resilience, some of which are analysed and discussed in the 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.

Food security in West Africa not only depends on productivity increases in marginal rural areas, but also on enhanced use of intensively farmed agricultural “niche” lands such as the urban and peri-urban spaces. They are characterised by easy market access and input availability which allows self-reinforcing processes of agricultural intensification. However, too little is known about resource use efficiencies, matter flows and negative externalities in these systems. Starting from general assessments (status quo analyses), the African-German UrbanFoodPlus (UFP) network develops and tests site-specific, farmer-tailored innovations. These directly address the above mentioned knowledge gaps in the fourWest African cities of Ouagadougou (Burkina Faso), Tamale (Ghana), Bamako (Mali), and Bamenda (Cameroon). At all locations farmers attempt to cope with increasing land pressure by cultivating along electrical power lines, on public property, and on undeveloped private land.
