“…Due to poor sanitation, lack of proper drainage system and lack of wastewater treatment plant, effluent from industries and domestic sewage is often discharged into streams, rivers and open gutters 14 . It is estimated that about 47% of households discharge their liquid waste into open gutters 20 . Farmers in both urban and city peripheries make use of wastewater for vegetable irrigation.…”

This paper assesses water quality that is used for vegetable irrigation in Tamale Metropolis, Ghana. A mixed-method of research design was employed in this study to collect and analyze the data based on survey instruments. The paper found that Escherichia coli (E. coli) that is usually used as an indicator of water contamination and heavy metals exist in all taken water samples. The mean concentrations of nutrients such as ammonia, nitrate, nitrite and phosphate were recorded as 0.022 mg/l to 5.98 mg/l for ammonia, 1.06 mg/l to 7.52 mg/l for nitrate, 0.031 mg/l to 0.056 mg/l for nitrate and 0.037 mg/l to 0.069 mg/l for phosphate. E. coli and Total Coliforms levels for Sanghani, Kamina and Waterworks from the laboratory analysis were recorded as 3.2 × 103 CFU 100 m/l and 5.5 × 102 CFU 100 m/l, 4.0 × 103 CFU 100 m/l and 1 × 102 CFU 100 m/l, and 2.1 × 103 CFU 100 m/l and 4.6 × 102 CFU 100 m/l respectively. To conclude, based on the measured parameters, water used for irrigation in the Tamale Metropolitan is polluted and may cause potential health risks. Therefore, farmers, traders and consumers need to apply further safety measures to make the vegetables safe.

“…According to 20 , the quality of the water use for vegetable irrigation in urban cities of Ghana is noted to be poor and below standards 23 . Antwi-Agyei reported that 160 irrigation water and 163 soil samples, 93% and 91% had levels of E. coli , respectively.…”

“…For instance, whereas earlier studies such as Parada et al (2021) appear to support increasing use of rain‐fed agriculture in urban cities, others such as Bougnom and Piddock (2017), Miller‐Robbie et al (2017) and Haldar et al (2021) argue for wastewater because of its potential benefits for urban agriculture. However, recent studies have raised concerns about the quality of wastewater in urban agriculture based on their discoveries of harmful organisms in wastewater used by urban farmers (Abdallah & Mourad, 2021; Amuah et al, 2022; Mayilla et al, 2015).…”

“…In Ghana, studies on the quality of water used for irrigation for vegetable and crop production in general have indicated different forms of contamination (Abdallah & Mourad, 2021; Amuah et al, 2022; Mayilla et al, 2015). There are the same indications in studies conducted in Cote D'Ivoire (Kambire et al, 2022; Koffi et al, 2012).…”

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.

“…According to Valipour and Singh (2016), studies on irrigation with treated wastewater have been conducted on other aspects such as soil, ground water, crops, health, irrigation equipment and other environmental issues with limited studies on management. In Tanzania for instance, recent studies concentrated much on the health and socio-economic issues related to the use of LQW (Kilobe et al, 2013;Nyomora, 2015;Mayilla et al, 2015, Msigala et. al.…”

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.
