“…4 Low production of cereal grain is mostly because of climate change that results in erratic rainfall patterns, drought and poor agronomic practices. 5,6 There is therefore a growing demand for wastewater treatment and reuse as a source of irrigation for improved farm yield. 7 However, reclaiming wastewater for agricultural use should ensure water treatment to remove pollutants that may have adverse impacts on plant productivity, seed germination and seedling growth.…”

BACKGROUND: Reclaimed wastewater is a potential source for irrigation, although its effect on seed germination and plant growth has not been widely investigated. The present study focused on treating wastewater by vermifiltration and investigating the effect on seed germination and seedling development of Zea mays, Triticum aestivum and Sorghum bicolor and their morphological, physiological and biochemical developments. A filter bed was constructed using indigenous and improved materials. The constituents used to develop the filter bed consist of matrix of garden soil, lateritic hardpan gravels and coconut coir inoculated with Eisenia fetida. RESULTS:The wastewater was obtained from a public septic tank toilet facility and contained 35-40% dry matter with high concentrations of total dissolve solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total nitrogen (N tot ) and phosphorus (P avail ). Portable water was used as the control. Vermifiltration of the wastewater was shown to be effective for the removal of 52-65% TDS, 56-62% TSS, 34-40% COD, 48-52% BOD, 56-62% N tot and 53-58% P avail . The results showed that the morphological, physiological and biochemical processes in Z. mays, T. aestivum and S. bicolor improved when seeds were subjected to treated wastewater.CONCLUSION: The present study demonstrated that a potential reuse of vermifiltered wastewater as a source of irrigation water with continuous monitoring of the water quality is productive and sustainable.

“…This preference for Eucalyptus is principally related to its high drought tolerance. In fact, they have a growth adaptation in the arid region and show rapid growth, tolerance to salinity, tolerance to drought and intense flowering (Saadaoui et al, 2017;Maaloul et al, 2019). Given the importance of this taxa, this area should be protected and valued for the multiple use of these species, E. camaldulensis and E. gomphocephala account for more than 80% of the Eucalyptus stand (Mechergui et al, 2019).…”

The genus Eucalyptus occurs in a large range of environmental conditions, mainly arid/semi-arid areas. It includes species with high capacity to survive with extremely low water potential. For that, our review shows an important effect of drought on Eucalyptus spp. plants’ resistance mechanisms and management strategies. In fact, water stress acts directly on growth, productivity, yield, it affects also response to pests and diseases, disturbs wood formation and essential oil yield. However, the general patterns of response to water stress varied among species, genotypes, hybrids and clones. To assume, reducing water loss in eucalyptus species is manifested by reducing leaves area, reducing gas exchange, increasing water uptake thanks to a prolific and deep root systems. A greater accumulation of osmolytes that gives rise to osmotic adjustment including carbohydrates especially cyclitols and quercitol, other amino acids and organic acids, also some proteins which play a vital role in sustaining cellular functions under drought conditions. More than that, water stress increases mainly the levels of pigments, chlorophyll fluorescence parameters, malondialdehyde (MDA), abscisic acid (ABA) and the biosynthesis of triacylglycerols (TAGs) in Eucalyptus species.

“…It also brings positive effects on the mitigation of global warming. Because of having solutes, TWW can have side effects on some plants, which needs further research (Reznik et al 2017;Maaloul et al 2019). Not all peri-urban agricultural activities result in ecosystem services.…”

People's participation in using treated wastewater as an approach for sustainability of ecosystem services, green spaces, and farmlands in peri-urban areas: the case study of Kalak-e Bala, Karaj, Iran

Water scarcity is the most significant challenge facing semi-arid and arid areas because fresh water is often transferred from other areas to these regions, and then discharged as wastewater. Irrigating agricultural lands and green spaces with treated wastewater (TWW) can be thus regarded as a way to reduce pressure on fresh water resources and lead to the utilization of ecosystem services, such as regulating and cultural ones. The most important factor affecting the expansion and sustainability of these areas is people's participation. Therefore, this study reflected on the weight of locals' willingness and attitudes as one of the most effective factors in the development of irrigation with TWW in peri-urban areas and ecological buffer zones. The main indicators were accordingly extracted from previous research and examined through a survey questionnaire, and then analyzed by the structural equation modeling (SEM) in the AMOS and LISREL software packages. The indicators were related to individuals' health in product consumption (health), people's activities in farmlands and green spaces (assurance), and users' distance from farmlands (accessibility). The study results revealed that the accessibility was the most important factor, and then health and assurance were effective in people's participation in agricultural activities in farmlands irrigated with TWW in peri-urban areas and increasing green-space buffer zones.
