Pollution of Water, Soil and Vegetables: Challenges to Growing Cities of Bahir Dar and Kombolcha, Amhara Region, Ethiopia
2013Mekonnen Getahun, Yihenew G. Selassie · Journal of Agricultural Science · Ethiopia
A study investigated the extent of contamination of soil, water, and vegetables from wastewater used for irrigation in urban agriculture in Bahir Dar and Kombolcha, Ethiopia. Soil, water, and vegetable samples were collected and analyzed. While heavy metal concentrations in soil were within permissible levels, wastewater samples showed high nitrate and phosphate levels, and boron concentrations in Borkena River and Lake Tana exceeded permissible limits for irrigation. Wastewater drained to Lake Tana exhibited high turbidity and very high BOD, and lettuce and Swiss chard accumulated higher levels of iron, manganese, and zinc.

2013CDR Aza-Gnandji, Yongxin Xu, Lincoln Raitt, Jonathan Levy · Water SA · South Africa (Cape Town)
This study explored the salinity of irrigation water from the Cape Flats aquifer in the Philippi farming area of Cape Town, South Africa, collecting water samples from boreholes and ponds in summer and winter. Concentrations of chloride, nitrate, potassium, and sodium exceeded target maximum limits set by DWAF and FAO guidelines. Groundwater and pond water were found to be brackish in most parts of the research area, with salinization primarily attributed to agricultural activities. The water is generally suitable for irrigation but requires caution for salt-sensitive vegetables.

2013Doreen Atkinson · African Journal of Range and Forage Science · South Africa
This paper critiques the assertion that commercialization of smallholder agriculture poses dangers for sustainable rangeland management in South Africa. It argues that a range of policy options are required, including commercialization and subsistence farming, large-scale and smallholder farming, various land tenure options, rural and peri-urban farming, and part-time farming. The case of municipal commonage land is used to demonstrate the effectiveness of flexible policy options regarding land ownership, farming scale, and the social nature of farming, but it is noted that effective institutional development is a key requirement in all cases.

2013Roseline J. Akinlade, Olubunmi Lawrence Balogun, Adekemi A. Obisesan, Akinlade, Roseline J., Balogun, Olubunmi L., Obisesan, Adekemi A. · AgEcon Search (University of Minnesota, USA) · Nigeria
This study analyzed the determinants of commercialization among 230 urban vegetable farmers in Oyo and Lagos states, southwest Nigeria, using primary survey data and a Tobit model. It found that farmers' participation in domestic and regional markets remains low due to various constraints, notably poor market access. The average farm size was 0.05ha, and the average market participation index was 0.73. Factors influencing commercialization included age, farm size, association membership, education, distance to market, and input costs. The study concluded that social capital significantly affects market participation, and recommended proactive support from governments and NGOs to facilitate farmer organizations and market linkages.

2012G. N. Egwu, John O. Agbenin · Archives of Agronomy and Soil Science · Nigeria
A study in northern Nigeria assessed cadmium, lead, and zinc contamination in soils and leaf vegetables (amaranthus, lettuce) irrigated with untreated wastewater. Total cadmium and zinc concentrations in soils exceeded safe limits, and lead and cadmium in edible portions of amaranthus and lettuce exceeded safe limits for human consumption by 7–17 times. The permissible limit for lead established for agricultural lands may not be suitable to ensure produce safety in urban and peri-urban agriculture in Kano.

2012Nancy Karanja, Mary Njenga, G.K. Mutua, Carl Johan Lagerkvist, E. Kutto, JJ Okello · Journal of Agriculture Food Systems and Community Development · Kenya (Nairobi)
A study in three peri-urban sites in Nairobi, Kenya, assessed heavy metal, nitrate, and pesticide residue levels in wastewater-irrigated kale. Elevated levels of boron, cobalt, chromium, copper, lead, zinc, and nickel were found in vegetables at two sites, with high soil loadings of nickel, arsenic, lead, chromium, copper, and zinc attributed to chicken manure. Pesticide residues of diazinon, cypermethrin, biternol, and profenofos exceeded permissible limits in kale at one site, suggesting consumers may ingest significant amounts of contaminants.

2012Sebastian U. Ugbaje, John O. Agbenin · International Journal of Environmental Studies · Nigeria
A pot experiment in Zaria, northern Nigeria, evaluated the chemical forms and phytoavailability of Cr, Ni, and Pb in savannah soil amended with two urban wastes and planted with sorghum. While urban waste application increased total metal concentrations in the soil, only Pb uptake by sorghum increased, with no corresponding increases for Cr and Ni. A single application of urban wastes significantly increased Pb uptake by sorghum, raising concerns about the long-term consequences of such applications in urban and peri-urban agriculture, especially regarding children's exposure to Pb.

2011H.S. Geyer, Bennie Schloms, Danie du Plessis, Amanda van Eeden · DOAJ (DOAJ: Directory of Open Access Journals) · South Africa (Cape Town)
An analysis of agricultural land consumption within the Cape Town urban edge between 2002 and 2007 revealed that low-density residential development is the primary consumer of high-potential agricultural land. Commercial, industrial, and informal residential developments had minimal impact on agricultural land loss. High-potential agricultural land is not adequately protected, and urban agriculture is constrained by competition with more profitable land uses like residential development.
