Abstract While the Middle East and North African (MENA) region is facing challenges to sustain water security, water reclamation has received increasing consideration as a favorable mitigating solution. Despite the availability of adequate technologies, economic, political, legal, social, and environmental constraints often hamper stakeholders, and especially decision makers, from exploiting the existing potential into solution implementation. In the present paper, a comprehensive assessment for water reclamation and reuse was developed. This assessment consisted of 4 objectives: 1) apply a decision-support tool (DST) for water reclamation potential for municipal wastewater, 2) apply a DST for simulating and estimating the lifecycle costs of project-related technologies for water reclamation (municipal and industrial wastewater, as well as drainage canal water), 3) assess the national-level conditions for water reuse with a multicriteria decision analysis (MCA), and 4) establish exemplary strategies, barriers, and measures for water reuse. The present MCA considered 6 thematic subjects: policy and institution, economy, society, water management, legislation, and environment. The assessment was applied to food and nonfood crop irrigation in Egyptian, Moroccan, and Tunisian case studies. For all defined case studies, adapted treatment trains that could treat wastewater to the desired quality at reasonable costs were identified and are presented in the present paper. Results showed that technological options are available for water reuse, but the concept is not widely implemented in Egypt, Morocco, and Tunisia. The present paper identifies key barriers and drivers for the implementation of water reclamation for irrigation. In particular, the considered countries showed different characteristics regarding efficient water management, water pricing, subsidies and wastewater tariffs, implementation of monitoring and reporting systems, or legal aspects regarding the use of reclaimed water for food crop irrigation. Further exploration of case studies on high potential water reuse and financially affordable wastewater reclamation, particularly case studies that explore the impacts of policies and practices across countries, would be useful for helping the MENA region improve their water security situation.

Abstract To achieve a water-secure world, water management should be approached from a multidimensional and integrative perspective, addressing the water-related issues of health, household supply, economics, the environment, and resilience to water-related and climate change hazards. Although water security has significantly improved since 2000 in Africa, there are still vast inequalities in access to water suitable in terms of quantity and quality, especially in rural areas. To achieve water-related sustainable development of African economies, a broad scope of innovative technological and management solutions is required, involving governments, research institutions, private sector parties, and civil society. This special series, composed of 8 papers, illustrates a selection of the most relevant results achieved by the 7 research projects selected and financed by the European Union under 2 dedicated Horizon 2020 calls in 2015: Water-5b-2015 “A coordination platform” and Water-5c-2015 “Development of water supply and sanitation technology, systems and tools, and/or methodologies.” The innovations presented in this special series include both technological advancements and w'ater management approaches, given that the development of water-related technologies in developing countries needs to be integrated into water management strategies and economic instruments. This special series aims to help policy makers take informed decisions on how to implement innovative approaches to increase water security in African countries.

The microbiome associated with plants used in phytodepuration systems can boost plant growth and services, especially in ecosystems dealing with recalcitrant compounds, hardly removed via traditional wastewater (WW) treatments, such as azo-dyes used in textile industry. In this context, we aimed to study the cultivable microbiome selected by Phragmites australis plants in a Constructed Wetland (CW) in Morocco, in order to obtain candidate inoculants for the phytodepuration of azo-dye contaminated WW. A collection of 152 rhizospheric and endophytic bacteria was established. The strains were phylogenetically identified and characterized for traits of interest in the phytodepuration context. All strains showed Plant Growth Promotion potential in vitro and 67% of them significantly improved the growth of a model plant in vivo compared to the non bacterized control plants. Moreover, most of the isolates were able to grow in presence of several model micropollutants typically found in WW, indicating their potential use in phytodepuration of a wide spectrum of effluents. The six most promising strains of the collection were tested in CW microcosms alone or as consortium: the consortium and two single inocula demonstrated to significantly increase the removal of the model azo-dye Reactive Black 5 compared to the non bacterized controls. |

Abstract Reuse of treated wastewater (TWW) for irrigation can be an effective strategy in Mediterranean countries to overcome the pressure on freshwater resources if its economic viability is demonstrated. In this work, the assessment of the economic feasibility of irrigation and nutrient management with TWW reuse was carried out in the citrus sector in the Souss Massa region of Morocco. Considering the effects of TWW reuse on yields, water, and fertilizer requirements, a mathematical nonlinear optimization model was used to identify the optimal allocation of land and nonuniform quality irrigation water and to assess the impacts on the economic performance of the citrus sector. Different water price and irrigation technology scenarios have been simulated. Overall results indicated that the reuse of TWW—with a current price higher than the conventional resource—must be subsidized to be proposed as a convenient alternative for irrigation. A reduction in the TWW price from its current level (0.23 Euro/m3) to a level equal to that of fresh water (0.15 Euro/m3) would encourage farmers to use TWW on 59% of the total cultivated area, leading to a 350 mm reduction in quantity of used fresh water per hectare.

Abstract In Agadir, a water-scarce Moroccan region, municipal and industrial wastewater is tertiary-treated to be reused in golf courses. Wastewater reuse has been constrained by severe clogging of emitters, which caused technical and financial problems. This study aimed to perform an in-depth characterization of the treated wastewater (TWW) in relation to its susceptibility to cause clogging, and to assess the capacity of an aeration post-treatment to reduce the clogging potential. The post-treatment consisted of injecting different airflows (0–33 L/(h Lreactor) into the TWW. The structural, morphological and elemental composition of the clogging matter collected in the irrigation pipeline was characterized using scanning electron microscopy, scanning transmission electron microscopy, X-ray diffraction and X-ray energy dispersive spectroscopy. The 15-day aeration post-treatment at 16.5 L/(h Lreactor) presented the best cost–benefit ratio. Organic matter was totally degraded. Calcium was reduced by 9%, bicarbonates by 54%. The analysis of the deposits induced by the aeration post-treatment revealed a relevant decrease of the major constituents of the clogging deposits found in the irrigation pipeline. The results show the effectiveness of post-aeration in biodegrading residual organic matter and precipitating several salts, thus reducing the clogging potential. |

Abstract The use of treated wastewater (TWW) as an alternative resource to fresh water (FW) for irrigation purposes is becoming increasingly important, especially in semiarid and arid regions. However, achieving success in crop production largely depends on the adoption of appropriate on-farm management strategies aimed at optimizing crop yields, maintaining soil productivity and safeguarding the environment. For this purpose, predictive models are of particular interest. A safe irrigation management (SIM) model developed and tested in this research was used to schedule irrigation under controlled management tailored to the use of 1) TWW and 2) FW and to reproduce farmers' strategies. These management strategies aim to improve actual irrigation practices, accounting for water quality, soil characteristics, and crop yield. The results of the application of SIM on a citrus farm in Souss-Massa, Morocco, show that the management strategy adopted by farmers withdraws considerable amounts of water and results in substantial drainage volumes compared to those in the SIM strategy. In the specific case of TWW, the strategy simulated by the SIM model resulted in a decrease in yield of approximately 4%, compared to the 23% decrease derived from the farmers' traditional strategy. Moreover, SIM allowed for great savings in terms of fertilizing elements and for the reduction in the movement of water and salts beyond the root zone, usually considered the main source of groundwater contamination. These results confirm the appropriateness of using prediction models and the accuracy of the SIM model in adapting irrigation strategies to TWW, which will be an integral part of the strategies that encourage their use in irrigated agriculture.
