“…Conversely, these topics have been considered in the last three years of the period (2015-2017), including detailed analysis about effects of saline-reclaimed waters and deficit irrigation assessed by remote sensing [71]. Wastewater reuse potential for irrigated agriculture [72], the use of constructed wetlands for the treatment and reuse of urban wastewater for irrigation [73], and how governance regimes shape the implementation of water reuse schemes [74] have also been considered.…”

The successes and failures of water reuse schemes are shaped by complex interrelationships between technological, economic, and socio-political factors. However, it has long been recognized that the main challenges to more effective water management are largely social rather than technical. This article reviews the recent literature (2007–2017) to analyze driving factors associated with farmers’ concerns and public perception of reclaimed wastewater for irrigation. The aim of the paper is to synthetize how both environmental and health risks and the yuck factor could be addressed in order to promote mutual understanding between farmers and the public. Results show: (1) how farmers and the public perceive environmental and health risks in a similar way, (2) how the yuck factor is more noticeable for the public than farmers, and (3) how constructed wetlands, reclaimed water exchange consortiums, product certification, and direct site visits to water reuse infrastructure could be promoted in order to foster understanding between farmers and the public. The article concludes by providing key research questions for managers and public authorities relating to how to focus on the study of technical and social issues related to water reuse.

“…Shortages of irrigation water along with reinforced pressures on regional available water resources owing to population growth, urbanization, industrialization, and climate change [1] are an important driver in the reuse of treated municipal wastewater (TWW) for agricultural activities, especially in the irrigation of rice (Oryza sativa L.) paddy fields. The reuse of TWW has been demonstrated to diminish water scarcity, alleviate the degradation of wastewater-receiving environments, and conserve other freshwater sources [2].…”

To obtain a high rice yield and quality for animal feed without synthetic fertilizers, an experiment with bench-scale apparatus was conducted by applying continuous irrigation with treated municipal wastewater (TWW). Uniform rice seedlings of a high-yield variety (Oryza sativa L., cv. Bekoaoba) were transplanted in five treatments to examine different TWW irrigation directions (“bottom-to-top” and “top-to-top” irrigation) and fertilization practices (with and without P-synthetic fertilizers) as well as one control that simulated the irrigation and fertilization management of normal paddy fields. The highest rice yield (14.1 t ha−1), shoot dry mass (12.9 t ha−1), and protein content in brown rice (14.6%) were achieved using bottom-to-top irrigation, although synthetic fertilizers were not applied. In addition, this subsurface irrigation system could contribute to environmental protection by removing 85–90% of nitrogen from TWW more effectively than the top-to-top irrigation, which showed a removal efficiency of approximately 63%. No accumulation of heavy metals (Fe, Mn, Cu, Zn, Cd, Ni, Pb, Cr, and As) in the paddy soils was observed after TWW irrigation for five months, and the contents of these metals in the harvested brown rice were lower than the permissible limits recommended by international standards. A microbial fuel cell system (MFC) was installed in the cultivation system using graphite-felt electrodes to test the capacity of electricity generation; however, the electricity output was much lower than that reported in normal paddy fields. Bottom-to-top irrigation with TWW can be considered a potential practice to meet both water and nutrient demand for rice cultivation in order to achieve a very high yield and nutritional quality of cultivated rice without necessitating the application of synthetic fertilizers.

“…The global demand on water is continuously increasing, where the world population has exceeded seven billions and is still growing. Not only the continuous population growth is requiring water for domestic purposes, but also the demand on food is increasing, which causes an increasing and a growing demand on water for irrigation (Ahmadi and Merkley, 2017;Kumar et al, 2017;Sarkar et al, 2017). The competition among different sectors of water users is increasing and agriculture is the most vulnerable sector since it is the main consumer of water.…”

Background: This study was conducted to evaluate the production of two fodder crops; common vetch (Vicia sativa L.) and Alfalfa (Medicago sativa L.) irrigated with treated wastewater. The study was implemented during summer 2015. Methods: Four water regimes were used in the experiment including: Irrigation with fresh water (control), fresh water supplied by 10 ppm N-P-K fertilizer, treated wastewater and treated wastewater supplied with 10 ppm N-P-K fertilizer. The crops were planted in 5 liters plastic pots in 4:1 v/v sandy to clay soil. The soil was analyzed before and after planting. The following plant parameters were recorded: Plant height, fresh weight, dry weight, leaves number/plant, fruit number/plant and fruit weight/plant. Result: using treated wastewater significantly increased production parameters, the highest production was obtained with treated wastewater supplied with 10 ppm N-P-K fertilizer (81.5 cm/plant higher in vetch and 112.5 cm/plant in alfalfa for plant height). When treated wastewater was used alone compared to fresh water higher fresh weights (62.8 g/plant) (82.33 g/plant (132 and 87.17 g/plant) for vetch and alfalfa were obtained respectively. Regarding the dry weight, irrigation with TWW produced 33.83 g/plant and 44.67 g/plant compared to 22 g/plant and 24.5 g/plant for plants irrigated with fresh water for vetch and alfalfa respectively. The results of soil analysis show an increase in soil content of nitrogen, phosphorus and potassium, as well as an increase in soil salinity and SAR values.
