“…In most developing countries, the poverty of farmers and retailers is a major issue contributing to less or no disinfection of fresh produce before marketing [83]. One washing container with water is used to wash several vegetables leading to contamination instead of disinfection [41].…”

Microbes are found all over the globe with some few exceptions, including sterilized surfaces. They include normal flora that is nonpathogenic, which contribute to the larger percentage, and pathogenic species which are few. Hence, the activities of humans cannot be completely separated from microbes. Thus, many pathogenic microbes have found their way into fresh fruits and vegetables which are a great source of a healthy diet for humans. The growing demand for fresh fruits and vegetables has necessitated larger production. The larger production of vegetables within the shortest possible time to meet the growing demand has placed them at a higher risk of contamination with the pathogenic microbes, making the safety of consumers uncertain. Study of sources of contamination and type of pathogenic etiological agents isolated from fresh fruits and vegetables includes Bacillus cereus, Campylobacter jejuni, Clostridium botulinum, E. coli O157: H7, Listeria monocytogenes, Salmonella spp., Shigella, Staphylococcus, and Vibrio cholera. Several measures have proven to be effective in controlling contamination of microbes and they include the establishment of surveillance systems to monitor the production chain and thoroughly washing vegetables with vinegar water. Saltwater and other washing techniques are effective but caution should be taken to make sure one does not use one cycle of water for washing all vegetables. The consumption of fresh fruits and vegetables is still encouraged by this review but significant measures must be taken to check the safety of these products before consumption.

“…Given the reality that no alternative sources of water for irrigation are available to these farmers, effluent from the WSPs will continue to be used as a source of irrigation water. Farmers will also continue to grow crops of their own choice and vegetable farming is a quick source of money during the dry seasons compared to other crops (Keraita et al, 2012). These two different lines of thinking on the use of effluent from the WSPs in food crops between the government and the community especially on vegetables production need a balance.…”

“…Agricultural water management contributes significantly to the reduction of poverty (Valipour, 2016 a, b). Urban and peri-urban agriculture has significant contribution to the poverty reduction by serving as a source of locally available produce and employing a substantial number of people (Keraita et al, 2012, Valipour, 2016. However, urban and peri-urban areas face limited supply of potable water to meet both the domestic uses and irrigation farming (United Republic of Tanzania [URT], 2002;Fraiture et al, 2010).…”

“…Proper treatment and good management of treated wastewater provides a reliable source of water during the dry season, permitting multiple crops production throughout the year. In addition, LQW irrigation contributes significantly to sustaining livelihoods, food security and the quality of environment (Keraita et al, 2012). An increased use of LQW in agricultural production has been reported to occur in various countries in the world (Amoah et al, 2007;World Bank, 2010;Keraita et al, 2012).…”

Knowledge on users' and regulators' views regarding obstacles on the use of low quality water forms the basis for the improvement of water reuse in food crops irrigation. A qualitative study was conducted to assess the obstacles to the use of low quality water for irrigation of food crops in urban and peri-urban areas in Tanzania. The study considered Morogoro urban and peri-urban areas as a case study due to the existence of paddy and vegetable production using the effluent from the waste stabilisation ponds. Both primary and secondary data were used. Primary data were collected through in-depth interviews with 22 key informants, and 4 focus group discussions with farmers. Content analysis was used in this study. Findings show that domestic wastewater was poorly disposed, waste stabilisation ponds as treatment facilities had limited management, and quality monitoring of effluent from the waste stabilisation ponds was limited to permit safe use of the effluent in food crops irrigation. The government officials were of the view that the effluent from the waste stabilisation ponds should not be used for leafy vegetables irrigation while farmers viewed vegetables farming as a quick source of income and livelihood strategy for many years. The study therefore suggests that the relevant agencies should improve the treatment of wastewater and quality monitoring of the effluent for safe use of low quality water for food crops irrigation in urban and peri-urban areas.

Studies on water use in urban agriculture in developing countries have largely focused on wastewater reuse and its associated health concerns. However, there is some heterogeneity in the choice of water sources of urban farmers in a developing country such as Ghana, where agricultural infrastructure is not fully developed. Therefore, this study explores the choice of water sources during the rainy and dry seasons by urban farmers since it has implications for food security in urban areas and beyond. Using chi-square and multinomial logit regression, this paper assesses urban farmers' choices for different water sources in Ghana during the rainy and dry seasons and examines the associated factors driving these choices. The results show that most urban farmers use rainwater and wastewater during the rainy and dry seasons, respectively, but small lakes/rivers are the least used during both seasons. Also, the choice of water sources at different locations is influenced by farm and non-farm characteristics. The paper concludes that there is heterogeneity in the choice of water sources among urban farmers at different locations during different seasons. We recommend that stakeholders involved in promoting and sustaining urban agriculture must help in building a solid infrastructure for sustainable irrigation.
