“…We saw commercial engagement and subsistence production in isolated fields, backyards and open-space sites. Similarly, Eaton and Hilhorst (2003) describe how differentiation in commercial orientation is a function of crop type rather than of location, with staples in Bamako and Ouagadougou destined for consumption and vegetables for sale, in both urban and peri-urban farms. In Kumasi too, type of farm did not dictate crops grown, as traditional subsistence tubers were grown in backyards as well as in peri-urban open-space sites (Nsiah-Gyabaah and Adam 2001).…”

“…Successful promotion of compost by the Ministry of Agriculture in Ouagadougou may also have contributed to the higher prevalence of its use there. Sewage is used as fertilizer in both our study cities (Eaton and Hilhorst 2003;Cofie et al 2005), but our random sample did not encounter any of the farmers concerned. There is a large-scale composting plant in Tamale, as in Ibadan and Accra (Agbola 2001;Etuah-Jackson et al 2001), but, as in those towns, it is beset by marketing issues.…”

“…Considering the work that has been done on fecal sludge application, such less-conventional nutrient sources or soil conditioners should also be considered (Eaton and Hilhorst 2003;Cofie et al 2005). UFP is working on the application of biochar as an alternative soil conditioner in the study cities.…”

163 Working PapersThe publications in this series record the work and thinking of IWMI researchers, and knowledge that the Institute's scientific management feels is worthy of documenting. This series will ensure that scientific data and other information gathered or prepared as a part of the research work of the Institute are recorded and referenced. Working Papers could include project reports, case studies, conference or workshop proceedings, discussion papers or reports on progress of research, country-specific research reports, monographs, etc. Working Papers may be copublished, by IWMI and partner organizations.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to provide evidence-based solutions to sustainably manage water and land resources for food security, people's livelihoods and the environment. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a tangible impact on poverty reduction, food security and ecosystem health.

“…Pueden provenir de diversas fuentes, como por ejemplo: agua de riego; residuos orgánicos parcialmente descompuestos (composta, basura orgánica, abonos), que se aplican frecuentemente debido a su bajo costo (Eaton et al, 2007); fertilizantes inorgánicos, plaguicidas, lodos residuales de origen municipal o industrial que pueden, por un lado, inhibir a la microbiota edáfica (Shivakumar et al, 2011) y, con ello, alterar procesos como la mineralización de materia orgánica y del aporte de nutrimentos a las plantas y, por otro lado, pueden ser absorbidos por las plantas y causar fitotoxicidad, o ser transferidos a la cadena alimentaria (Paraíba et al, 2011). …”

“…So far, studies that have dealt with water and nutrient management and use efficiencies in West African vegetable production systems are still very limited, and most of them have been either qualitative or based on on-station trials (Tamini and Mermoud 2002;Eaton and Hilhorst 2003;Mermoud et al 2005;Akponikpè et al 2011) which may not be representative of UPA vegetable gardens. Most investigations were also restricted to only part of the year, even though vegetable cropping is a yearround activity and climatic variables that govern crop growth, evapotranspiration and leaching present a seasonality.…”

Urban agriculture increasingly supplies food and non-food services to the rapidly growing West African cities. However, with its typically heavy use of fertilizers and uncontrolled use of water, it bears severe risks of soil and groundwater pollution. This study was carried out in Bobo Dioulasso (Burkina Faso, West Africa) at two commercial gardening sites. It aimed at performing a detailed characterization of farmer's water and nutrient management strategies.Four vegetable crops were monitored (tomato, cabbage, carrot and lettuce). Water inputs (rainfall and irrigation), nutrient inputs (organic and mineral fertilizers and nutrients in irrigation water) and crop uptake were monitored over a 1-2-year period. In addition, pan lysimeters allowed monitoring drainage. Depending on the site, 3-8% of the input water was lost by drainage, i.e., as much as 293 mm/year at one of the sites. During the dry season, when the farmer has full control over the water supply, water application exceeded plant requirements by as much as 40%, which reveals inefficient water use. Up to 800 kg N ha -1 , 140 kg P ha -1 and 500 kg K ha -1 were applied for a single crop cycle. With few exceptions, crops tended to be strongly over-fertilized, except for K at one of the two sites. Nutrient supply exceeded crop requirements by 109 to 2,012 kg N, 66 to 450 kg P and 0 to 393 kg K per year. These results, in combination with the large observed rates of drainage, are indicative of a high risk of nutrient leaching and groundwater contamination. The partial factor productivity of nutrients tended to be low. These results therefore suggested that there is scope to substantially reduce nutrient application rates in these systems without adverse effects on yields, which would be beneficial for groundwater resources and improve the economic returns.
