In the realms of Climate change impact, economic and population growth, and pollution, Water security, and sustainable development are paramount, for addressing the food-water-energy nexus and mitigating the impact of the cited drawbacks. The presented paper in the first part, emphasizes water security and sustainable development notions. In 2015 s the 2030 agenda were approved by 193 members of the United Nation, it consists of 17 goals (SDG) for environmental sustainability, social inclusion, economic development, peace, justice, good governance, and partnership. The 6th target of SDG is dedicated to clean water and sanitation since it is considered as one of the central focuses of Sustainable Development Goals. The second part is focused on Moroccan's water management plans. This latter elaborate a legal framework for water use, the law n° 36-15 that comprises the protection of human health through the regulation of exploitation, and provision of sanction. The green Morocco Plan (PMV) which aims first to develop modern agriculture aligned with the world global market requirement, and second to eliminate poverty by helping smallholder farming. The 140 dam's that Morocco counts provide strong support to economic growth. However, under the actual uncontrollable changing rate, Morocco is still threatened by low "water security", the access of drinkable water and sanitation services are improved but not totally covered, Moreover, the climate change * This research was supported by the project, which has received funding from the

The 2030 Agenda for Sustainable Development aims to reach 17 Sustainable Development Goals (SDGs). The SDGs 6 deals with water security, which refers mainly to ensure availability and sus-tainable management of water. The present study aims to enhance reservoir performance under climate change to deal with water scarcity. For this purpose, we proposed a new methodology where precipitation and evaporation data provided through temporal downscaling are leveraged by a real-time management algorithm coupled with the Hydrologic Modeling System (HEC-HMS). The real-time dam management algorithm is based on water balance equation and rule curves. It provides information about (1) dam storage, (2) dam release, (3) dam evaporation, (4) dam diversion, (5) spilled water volume, (6) emergency spilled water volume, (7) dam inflow, (8) irrigation demand, (9) irrigation shortage, (10) dam siltation, (11) dam hydropower produc-tion, ( 12) hydropower energy income. The developed approach has been applied to the Hassan Addakhil multipurpose reservoir in Morocco. The result shows that the dam reliability and resili-ence have increased from 40% to 70% and from 16% to 66%, respectively, while the vulnerability remained constant. Additionally, this study has pointed out that the installation of a hydropower plant is an opportunity to produce clean electrical energy and generate an income enough to cov-er different costs related to dam management and maintenance. Therefore, the real-time man-agement tool developed in the framework of this project can significantly enhance reservoir per-formance.

This article proposes a methodology for generating hourly rainfall from daily rainfall data. It was evolved as a tool for managing flood risks on Ziz catchment, by means of Intensity-duration-frequency curves (IDF) and designed hyetograph of Chicago. The study area is located in the south-eastern part of Morocco, and did not have a monitoring station for hourly rain measure, the methodomogy consist of determinating the rainfall intensity for 24 h using IDF, then estimating the hourly rainfall using Chicago formula, in order to assess the accuracy of the method the resulting hyetographs was introduced into the semi-distributed hydrological model HEC HMS to simulate hourly flow, which was compared to the observed one. The obtaining results exhibit that the observed value is positively correlated with those obtained by the above method, as shown by the correlation coefficient and the Nash-Sutcliffe. This approach can deal with instantaneous water management issues by tackling flood risks and providing an appropriate range of data for the dam’s management.

Fenugreek (Trigonella foenum-graecum L.) has long been used as a medicinal plant for the treatment of nutritional and metabolic dysfunctions. It has been shown that the daily intake of fenugreek seeds improves feeding behavior in animals. A number of studies have also suggested a link between Fenugreek seeds extracts and fertility but have yielded contradictory results. In this paper, particular attention has been paid to the impact of consumption of the aqueous extract of fenugreek seeds, prepared according to the traditional Moroccan method, on the spermatic parameters and the pathophysiology of the reproductive system of Wistar rats receiving 450 and 900 mg / kg /day, respectively. Our study results show the benefits of fenugreekseeds aqueous extract, used in the traditional Moroccan pharmacopoeia on appetite stimulation and weight gain without any significant impact on the fertility and the reproductive performances. Both quantitative and qualitative analysis of sperm parameters (morphology, mobility and vitality) showed no significant variation compared to the controls. In addition, histological examination of seminiferous tubules and reproductive accessory glands (prostate and seminal vesicles) in fenugreek treated rats showeda normal tissue architecture without visible lesion. These data exclude all potential risks from the consumption of aqueous extract of fenugreek seeds on the fertility and reproductive function in male rats. However, taking into account other data from the literature, this regular consumption should be closely monitored in order to allow the organism to fully benefit from a multiple phytotherapeutic virtues of this plant.

Future projection shows that the availability of freshwater per capita will decrease to 560 m3/year by 2030 in Morocco. In this realm of adopting efficient irrigation, alternatives become a priority to overcome water shortage. The presented study aims to investigate theoretically the likelihood of improving irrigation efficiency at the plot level of the Middle Sebou and Innaouene downstream perimeter using 75% of the total irrigation water requirement (IWR), based on the successful results obtained by the Moroccan National Institute for Agronomic Research. The methodology consists of the extraction of monthly evaporation data from MODIS16A2 and process it under Google Earth Engine (GEE); data that are used in the second part of the study, which aims to assess the efficiency of deficit irrigation on a plot of 2,500 olive tree, using three main indexes; olive three height (cm), Stomatal conductance (mmol H2O m−2 s−1), and olive tree growth (cm). The results show that 0.75 of full irrigation could save 17% of the total water used, reducing the water irrigation supply by an average of 5 Mm3, with a slight decreasing of the olive production, estimated as 0.5 t/ha. Furthermore, water use efficiency and water productivity have been enhanced under deficit irrigation by respectively 0.25 kg/m3 and 0.54 Dh/m3. In economic terms, the result shows that with deficit irrigation, the decision-maker, or the farmer, could save about 5 million m3 per year, which is a boost to the global economy if the method is transposed and applied to other Moroccan regions and also a support for the new agricultural strategy called Generation Green.
