Abstract:

Bricks manufactured, based on dredged sediments extracted from Tangier and Larache ports in Morocco were investigated. Chemical, physical, geotechnical, mineralogical and environmental characterizations studies of ports dredged sediments were performed. Partial substitution of natural clay by dredged sediments was achieved with different substitution rates by weight (20%, 40%, 50%, 60% and 70%) to manufacture brick samples at the laboratory scale. The compressive strength was the factor determining the optimal substitution rate of the natural clay. Compressive strength values of fired bricks with different rates of sediments incorporated show that the manufactured bricks have mechanical characteristics relatively close to natural clay until 60% substitution for Larache port dredged sediment (SL) and until 50% for Tangier port dredged sediment (ST). The results in this study confirm that dredged sediments from the ports of Tangier and Larache can be used as an alternative raw materials resource for the manufacturing of fired bricks.

En este artículo se recoge la correspondencia del judío David Cardoso Núñez, primero con el cónsul de España en Larache, Tomás Bremond, y luego con el cónsul español en Tánger, Juan Manuel González Salmón. Bremond comisionó a Cardoso para que expidiera las patentes de sanidad a las embarcaciones españolas que fueran al puerto de la Mamora. González Salmón eligió a Cardoso como confidente en Larache, cargo que desempeñó desde finales de 1783 hasta octubre de 1787. Más tarde, en 1792, Cardoso escribe a González Salmón en nombre propio, en el del embajador Aḥmad al-Dalīmī y en el del príncipe Mawlāy ‛Abd al-Salām, lo que origina la correspondencia que aquí presentamos.

Abstract:

Abstract A serious environmental problem can arise from the presence of pesticides in soils and waters. Hence, in this study we have carried out the adsorption of the Thiabendazole fungicide onto four soils collected from several areas in Morocco as Larache, Laouamra, Ksar kebir and Tlata drissana. Physicochemical properties, elemental analysis, X-ray diffraction (XRD) were investigated to characterise the four selected soils. The experimental equilibrium data were analysed using Langmuir, Freundlich models. The equilibrium data were best described by a Langmuir model for all adsorbents. The maximum estimated adsorption capacity was 0.747 mg∙g−1, 0.751 mg∙g−1, 0.473 mg∙g−1 and 1.083 mg∙g−1, for Larache, Laouamra, Ksar kebir and Tlata drissana soils, respectively.

Abstract:

Abstract In this paper, a tecto-sedimentary evolution model of the northwestern external Rif zones (Morocco) is proposed. It is based on the study of structural relationships and the biostratigraphic and sedimentologic analysis of different Tertiary syn-tectonic units. This zone shows alternating foredeep basins and anticlinal ramps with a NNW-SSE structural trend and a vergence toward the WSW. The trend of turbiditic bodies and palaeocurrent directions (from the SSE to the NNW) are parallel to the regional tectonic strike. Sidi Mrayt and El Habt basins are filled with syn-tectonic middle Eocene to middle Miocene sediments; The Habt basin is subdivided in two sub-basins: Asilah-Larache and Rirha-Gzoula. The deposits are distributed in two separated turbiditic complex, each one including a stacking of turbiditic systems. The Rirha-Gzoula and Asilah-Larache sub-basins are located in front of two anticline ridge structures made up of Upper Cretaceous and Lower Eocene material; they are respectively Boujediane and Arbaa Ayacha anticlines. The distribution of turbiditic bodies, unconformities and structural relationships within the thrusts and folds system in the northwestern external Rif indicate the progression toward the external zones of fault-propagation folds and associated basins.

Abstract:

<p><span lang="EN-US">The agriculture sector in the Tangier-Tetouan-Al-Hoceima-Region (Northern Morocco) contributes a significant percentage to the national revenue. The Larache Province is at the regional forefront in agriculture terms due to its large irrigated areas. Golden-Gogi is a biological farm located in the Larache Province, and its objective is to produce organic crops. Besides climate change, this farm suffers from biotic factors such as snails and insects. These problems cause diseases in plants, resulting in massive crop production losses. Early detection of disease and biotic factors in plants is a difficult task for farmers, but it is now possible thanks to artificial intelligence. For that reason, we aim to contribute to this Province by comparing the well-known models in machine learning (ML) and deep learning (DL) used in early plant disease detection to specify the best-classifier in terms of detecting mint plant diseases. Mint plant is a major crop on the Golden-Gogi farm, and its dataset was collected from there. As per findings, DL classifiers outperform ML classifiers in disease detection. The best-classifier is DenseNet201, with high accuracy of 94.12%. Hence, the system using DenseNet201 offers a solution for farmers of this Province in making urgent decisions to avoid mint yield losses.</span></p>

Abstract:

Abstract The symbolic values that speakers attribute to certain linguistic features constitute an important sociolinguistic topic which, barring a few seminal works, has not drawn much attention from scholars working on Maghrebi Arabic, and more specifically, Moroccan varieties. The present paper aims to deepen our understanding of metalinguistic representations of Jebli, a sedentary rural variety of Moroccan Arabic, within the speech communities of Larache and Ouezzane, two urban centres lying on the southern periphery of the Jbala region of Northern Morocco. We first analysed several samples of performed speech taken from an online Moroccan comedy sketch series entitled Jebli & Beldi, which includes a character epitomizing the Jebli accent, in order to identify those salient linguistic features that are perceived as being typically Jebli. As these phonetic and morphosyntactic traits are consciously selected in performed speech, it may be assumed that they make up a linguistic stereotype. We then asked a group of informants in the cities of Larache and Ouezzane to describe what they regarded as the typical features of Jebli speech and also their attitudes towards these features. The results of our study show that the features informants named partly coincided with our own sketch-based selection, and their attitudes towards these features were generally negative. These features did not appear in the speech of most informants, suggesting either their absence in their dialect or a deliberate avoidance strategy on their part. A small number in fact used these features but denied doing so, suggesting that the features are socially stigmatized. We argue that the symbolic values ascribed to some typical Jebli features may trigger their avoidance, which in turn may generate linguistic variation and even lead to linguistic change.

Abstract:

Un interesante y desconocido capítulo de la persistencia de las formas barrocas en la arquitectura española del siglo XVIII se encuentra en dos ciudades de Marruecos: Larache (لعرائش - ا Al Araish) y Tánger (طنچة - Tanja). En estas capitales, el rey Carlos III ordenó construir dos edificios que funcionaron como legaciones diplomáticas ante el Sultán. En ellos se mantiene todavía un cierto carácter manierista, aunque situado ya en una cronología del barroco más tardío. Los proyectos fueron realizados por los arquitectos Juan Fernández y Francisco Pérez Arroyo, que desplegaron programas acordes con la representatividad diplomática a la que estaban destinados. Las vicisitudes históricas y los cambios de uso han marcado las transformaciones de estos dos palacios que subsisten en nuestros días como unos grandes desconocidos, a pesar del importantísimo papel que desempeñaron durante muchos años.

Abstract:

Este artículo estudia la memoria histórica sobre el colonialismo entre los habitantes del antiguo Protectorado español en Marruecos. Se basa en una investigación de campo realizada sobre el terreno entre 2019 y 2022. Para este trabajo en concreto se ha seleccionado una muestra de 13 informantes de Tetuán y Larache, con una media de edad superior a los setenta años, y que vivieron la época colonial durante su infancia o su juventud. Su memoria del Protectorado tiene un claro sesgo favorable, aunque con ciertos matices. Del mismo modo, se enuncia un discurso crítico con respecto al posterior proceso de independencia. Todo ello se ajusta a la ambivalencia característica de las relaciones entre colonizados y colonizadores. El discurso de estos informantes reproduce, pero también contradice, distintos aspectos del antiguo discurso colonialistaespañol y del discurso nacionalista marroquí.

Abstract:

Morocco's Atlantic coastline stretches from Tangier to Lagouira over a distance of around 3,000 km. It displays considerable geomorphological diversity depending on the structural domains, the nature and age of the terrain adjacent to the coastal profile, and even the degree of human covetousness and activity. In addition to a wealth of climato-eustatic records, coastal sedimentary dynamics, and prehistoric seismicity, there is evidence of an alarming retreat of the shoreline at sites such as Larache, Rabat, Safi, and Agadir. A project to research and map vulnerable sites with a view to forecasting risks in the field of coastal zone development is needed to avoid the dangers of marine aggression, which is likely to be amplified by extreme climate change and anthropogenic action in the context of increasingly strong littoralization.

Abstract:

El norte de Marruecos, territorio que durante la primera mitad del siglo XX estuvo bajo la administración española en forma de protectorado, fue una zona en la que se realizaron interesantes proyectos urbanos y arquitectónicos. En este artículo estudiaremos el intento por implantar un modelo de arquitectura colonial a lo largo de los años cuarenta, basado en formas clásicas que se inspiraban en los estilos herreriano y barroco. En el fondo, se pretendía crear un nuevo estilo basado en el rechazo de los modelos cosmopolitas y en la búsqueda de las raíces más clásicas y castizas de la arquitectura española. Un nuevo equipo de arquitectos dirigido por Pedro Muguruza acometió este proyecto, que cuenta con importantes realizaciones tanto en el campo del urbanismo como de la construcción arquitectónica, y que se desarrolla en las capitales de Tetuán, Larache, Alcazarquivir, Tánger o Nador.

Este artículo analiza en primer lugar las circunstancias que condujeron a que la vigilancia y mantenimiento de los presidios de Larache y Mamora quedasen vinculadas desde su conquista —en 1611 y 1614 respectivamente— hasta 1641 a los duques de Medina Sidonia. A lo largo de este periodo, la falta de concreción administrativa de este cometido asumido por los aristócratas andaluces fue el origen de conflictos y fricciones con la corte regia que pusieron de manifiesto la paradójica situación creada, según la cual cuanto mayor era la autonomía de mando que iban alcanzando los duques, mayor era el esfuerzo económico que les suponía, pese a sus reiteradas demandas para que se encontrase una solución financiera estable. Así mismo, se analizan algunos expedientes que se ensayaron para tratar de alcanzar un equilibrio. Una serie de esfuerzos que el experimento de la contribución única de la sal terminó obligando a abandonar en 1631-1635.

The estuary of the Loukkos River is a complex ecosystem where various factors affect the quality of water. Our study is assessing the degree of water pollution in the complex of the lower Loukkos wetland’s surface water, which is situated at the river mouth of the Loukkos river in the eastern periphery of Larache city. To realize this objective, we collected water samplings from five area sites during summer period from May to August 2016 to analyse eight parameters physicochemical including dissolved oxygen (DO), temperature, pH, electrical conductivity, turbidity, salinity, suspended matter and nitrates. This study was accompanied by a bacteriological analysis relating to the enumeration of total coliforms and faecal coliforms, intestinal enterococci and reducing anaerobic sulphites. The analysis’s results shed lights on factors of contamination and collaborate to the physicochemical evaluation and bacteriologic quality of surface water. The quality indicators spatialization reveals interactions between the various phenomena acting on the functions of this Ramsar site.

Abstract:

The characterization of building materials is a key tool to assess deterioration processes and improve potential restoration works of archaeological sites. The aim of this paper is to identify and characterize the most important building stones used in the construction of the Roman city of Lixus (Larache, Morocco) by means of petrographic and petrophysical techniques. Based on the visual analysis of the monuments, three major building stones (i.e. lithotypes) have been identified: i) Oligocene sandstones, ii) Quaternary sandstones and iii) Quaternary conglomerates. Based on the analysis of the regional geology and exploitation marks, these three lithotypes have been recognised to crop out in the surroundings of Lixus and the quarries, presumably Roman in origin, recognized. The Oligocene sandstone is the primary building stone in Lixus as it forms and crops out extensively in the Tchemmis hill, at the top of which the city is settled. The Quaternary sandstones and conglomerates, which represent nearshore deposits and eolianites, crop out along the Atlantic coast where they form part of the cliffs next to Larache. Petrographic results indicate that lithotypes differ notably in grain size, ratio of detrital to allochemical components, and the configuration of their porous system. Mechanical analysis shows that the Oligocene sandstones are more resistant to compression than the Quaternary sandstones and conglomerates, the latter exhibiting relatively low compressive strength. The Oligocene sandstones, which display scarce porosity and permeability, show a hydric behaviour characterized by a very low degree of absorption and desorption water, likely resulting from a poor connectivity of the pore network. Contrary to the latter lithotype, the Quaternary sandstones, which exhibit very high porosity and permeability, display a hydric behaviour characterized by high degree of both absorption and desorption of water. This is attributed to the low degree of cementation compared to porosity of this lithotype and the excellent connectivity of the porous network. Finally, Oligocene and Quaternary sandstones do not show a significant weight loss after the accelerated artificial aging test, indicating that both are slightly affected by salt crystallization and presumably ice formation. Results indicate that the relatively fine state of conservation of the building rocks of Lixus is linked to intrinsic factors such as mineralogy and petrophysical characteristics together with the favourable effect of the climatic condition of the study area.

Abstract:

In recent years, changes in climate, land cover, and sociodemographic dynamics have created new challenges in wildfire management. As a result, advanced and integrated approaches in wildfire science have emerged. The objective of our study is to use geospatial analysis to identify strategic responses to wildfires in the Tangier-Tetouan-Al Hoceima (TTA) region, widely reputed to exhibit the most significant incidences of wildfires in Morocco. We adopted a combined approach, using burned area products (Fire_CCI51: 2002–2020) from the Moderate Resolution Imaging Spectroradiometer (MODIS) and active fires from the Fire Information for Resource Management System (FIRMS: 2001–2022) and processing them with spatiotemporal statistical methods: optimized hotspot analysis (OHA) and emerging hotspot analysis (EHA). The main findings indicate that the TTA region recorded an average of 39.78 km2/year of burned areas, mostly located in forests (74%), mainly cork oak and matorral stands (50%). The OHA detected hotspots covering 2081 km2, with 63% concentrated in the provinces of Chefchaouen and Larache. Meanwhile, clusters of EHA extended over 740 km2 and were composed of the oscillating coldspot (OCS) and oscillating hotspot (OHS) patterns at 50% and 30%, respectively. Additionally, an average of 149 fires/year occurred, located mostly in forests (75%), mainly cork oak and matorral stands (61%). The OHA detected active fire hotspots covering 3904 km2, with 60% located in the provinces of Chefchaouen and Larache. Clusters of EHA over 941 km2 were composed of the oscillating hotspot (OHS) and new hotspot (NHS) patterns at 57% and 25%, respectively. The prevalence of the oscillating and new models mirrors, respectively, the substantial fluctuations in wildfires within the region alternating between periods of high and low wildfire activities and the marked increase in fires in recent times, which has occasioned the emergence of novel hotspots. Additionally, we identified six homogeneous wildfire zones to which we assigned three strategic responses: “maintain” (73% of the territory), “monitor and raise awareness” (14% of the territory), and “reinforce” (13% of the territory). These strategies address current wildfire management measures, which include prevention, risk analysis, preparation, intervention, and rehabilitation. To better allocate firefighting resources, strategic responses were classified into four priorities (very high, high, medium, and low). Last, the wildfire zoning and strategic responses were validated using burned areas from 2021 to 2023, and a global scheme was suggested to assess the effectiveness of future wildfire measures.

Full text

Abstract:

Northwestern Morocco is characterized by highly anthropized landscapes under the combined effect of agricultural intensification, resource overexploitation, urbanization, and tourism, but also local reforestation. Reconstructing the recent changes in vegetation in the region of the lower valley of the Loukkos river near Larache and their relationship to the settlement history are particularly helpful for understanding the processes at work within the landscape construction. The geohistorical approach combines paleoenvironmental, documentary, and historical data. The last few centuries have seen the emergence of wooded stands, in which cork oaks are a structural element. As forests were retreating, parklands intended for agriculture, agroforestry, and herding, like the Spanish dehesa and Portuguese montado, began to emerge. Nearly all of them have disappeared today, but we can identify their legacy and evaluate their cultural significance through comparing them with their counterparts in the Iberian Peninsula, but also in other areas of Morocco. Their deep historical roots give this landscape an evolving heritage character that is directly linked to the communities’ lifestyles, culture, and history.

Abstract:

Unlike the other hemoglobinopathies, few researches have been published concerningα-thalassemia in Morocco. The epidemiological features and the mutation spectrum of this disease are still unknown. This regional newborn screening is the first to studyα-thalassemia in the north of Morocco. During the period from January 2015 to December 2016, 1658 newborns umbilical blood samples were investigated. Suspected newborns were screened forα-globin defects using Gap-PCR and Multiplex Ligation-dependent Probe Amplification technique. The prevalence ofα-thalassemia, its mutation spectrum, and its allelic frequencies were described for the first time in Morocco. Six differentα-globin genetic disorders were detected in 16 neonates. This screening valued the prevalence ofα-thalassemia in the studied population at 0.96% and showed the wide mutation spectrum and the heterogeneous geographical distribution of the disease. A high rate of carriers was observed in Laouamra, a rural commune in Larache province. Heterogeneity ofα-globin alleles in Morocco explains the high variability ofα-thalassemia severity. This diversity reflects the anthropological history of the country. These results would contribute to the prevention of thalassemia in Morocco directing the design of a nationwide screening strategy and awareness campaign.

Abstract:

Agriculture is an important sector for developing countries and farmers. Recently, numerous techniques for increasing agricultural productivity have been utilized. However, different issues are still encountered by farmers including various plant diseases. Plant diseases diagnoses are challenging research, and they should be analyzed and treated by detecting the diseased plant leaves. For that reason, in this paper, we develop our proposed architecture using convolutional neural networks (OP-CNN) as a computer-aided to detect and diagnose plant diseases. The proposed architecture can assist farmers in increasing both the quantity and quality of their agricultural productivity. Besides this, the OP-CNN helps to reduce disease prevalence through early detection. The performance of our proposed model is compared with other convolutional neural networks (CNN) architectures in order to validate its capability. The strawberry dataset was employed to train and test the models since the strawberry is one of the main crops in the Larache Province (Morocco). The experimental tests demonstrate that our proposed OP-CNN reaches the highest values versus DenseNet121, VGG19, and ResNet50 with 100%, 99%, 97%, and 63% respectively for classification accuracy, 100%, 100%, 98% and, 79% respectively for precision, 100%, 99%, 97%, and 63% respectively for recall, and 100%, 99%, 97%, and 58% respectively for "F" _1Score.

Abstract:

AbstractThe high precipitation variability over North Africa presents a major challenge for the population and the infrastructure in the region. The last decades have seen many flood events caused by extreme precipitation in this area. There is a strong need to identify the most relevant atmospheric predictors to model these extreme events. In the present work, the effect of 14 different predictors calculated from NCEP–NCAR reanalysis, with daily to seasonal time steps, on the maximum annual precipitation (MAP) is evaluated at six coastal stations located in North Africa (Larache, Tangier, Melilla, Algiers, Tunis, and Gabès). The generalized extreme value (GEV) B-spline model was used to detect this influence. This model considers all continuous dependence forms (linear, quadratic, etc.) between the covariates and the variable of interest, thus providing a very flexible framework to evaluate the covariate effects on the GEV model parameters. Results show that no single set of covariates is valid for all stations. Overall, a strong dependence between the NCEP–NCAR predictors and MAP is detected, particularly with predictors describing large-scale circulation (geopotential height) or moisture (humidity). This study can therefore provide insights for developing extreme precipitation downscaling models that are tailored for North African conditions.

Abstract:

Despite a long history of research, interactions between the Tiwanaku polity of the Andean Middle Horizon (ca.A.D. 500-1100) and the San Pedro de Atacama oases of northern Chile remain controversial. Here, we investigate Middle Horizon interactions through an isotopic identification of the geographic origins of individuals buried in San Pedro de Atacama cemeteries and present the largest radiogenic strontium isotope dataset generated, to date, for the Andes. For individuals in Middle Horizon San Pedro de Atacama cemeteries ofCasa Parroquial, Coyo Oriental, Coyo-3, Larache, Quitor-5, Solcor-3, Solcor Plaza, Solor-3, and Tchecar Túmulo Sur, mean tooth enamel and bone87Sr/86Sr = .70834 ± .00172 (2σ, n = 273). Overall, the mean87Sr/86Sr values from Middle Horizon San Pedro de Atacama cemeteries support the idea that interactions between Atacameños and inhabitants of other regions varied by ayllu, an Andean kin-based community structure, with some ayllus incorporating individuals with a wider variety of geographic origins than others. When our interpretations of the radiogenic strontium isotope data are contextualized with analyses of mortuary behavior and recent biodistance analyses, we argue that the San Pedro de Atacama oases appear to be have been inhabited by culturally and biologically diverse groups, rather than by large numbers of colonists from the Tiwanaku capital and the Lake Titicaca Basin.

Abstract:

Late blight of potato (Solanum tuberosum L.) caused by Phytophthora infestans (Mont.) de Bary first appeared in Africa in 1941. It has been observed sporadically in Morocco for decades but only recently became a major problem. Significant losses have been recorded in the last two growing seasons in spite of the use of various disease control programs that included combinations of systemic and protectant fungicides. Phytophthora infestans was cultured from diseased foliage collected from commercial potato fields near Larache, Morocco. Isolates were analyzed to determine pathogenicity on several potato and tomato cultivars, mating type, genotype at two allozyme loci (2), and relative sensitivity to metalaxyl. Responses of the isolates to metalaxyl were assayed by mycelial radial growth on metalaxyl-amended agar, by floating leaves inoculated with P. infestans on metalaxyl solutions, and via potato tuber disks placed on filter paper saturated with metalaxyl solutions (1). Koch's postulates were completed; all isolates were pathogenic to potato and tomato cultivars tested, are consistent with the A1 mating type, and have the same allozyme pattern (Gpi 100/100, Pep 92/100) as US-6 genotype. All tests indicated resistance to metalaxyl up to 250 ppm. References: (1) K. L. Deahl et al. Am. Potato J. 70:779, 1993. (2) S. B. Goodwin et al. Plant Dis. 79:1181, 1995.

Abstract:

Oceanic energy sources, notably offshore wind and wave power, present a significant opportunity to generate green hydrogen through water electrolysis. This approach allows for offshore hydrogen production, which can be efficiently transported through existing pipelines and stored in various forms, offering a versatile solution to tackle the intermittency of renewable energy sources and potentially revolutionize the entire electrical grid infrastructure. This research focusses on assessing the technical and economic feasibility of this method in six strategic coastal regions in Morocco: Laayoune, Agadir, Essaouira, Eljadida, Casablanca and Larache. Our proposed system integrates offshore wind turbines, oscillating water column wave energy converters, and PEM electrolyzers, to meet energy demands while aligning with global sustainability objectives. Significant electricity production estimates are observed across these regions, ranging from 14 MW to 20 MW. Additionally, encouraging annual estimates of hydrogen production, varying between 20 and 40 tonnes for specific locations, showcase the potential of this approach. The system’s performance demonstrates promising efficiency rates, ranging from 13% to 18%, while maintaining competitive production costs. These findings underscore the ability of oceanic energy-driven green hydrogen to diversify Morocco’s energy portfolio, bolster water resilience, and foster sustainable development. Ultimately, this research lays the groundwork for comprehensive energy policies and substantial infrastructure investments, positioning Morocco on a trajectory towards a decarbonized future powered by innovative and clean technologies.

Abstract:

De nos jours, le Maroc a mobilisé plusieurs efforts dans le cadre de l’engagement sociétale des entreprises, afin d’introduire des nouvelles préoccupations dans le fonctionnement quotidien de ces dernières. Certes, l’importance donnée aux risques psychosociaux reste encore largement sous-estimée et sous étudiée, laissant de nombreux employés exposés à des conditions de travail préjudiciables pour leur santé mentale, sans aucune stratégie ou règlement qui encadrent ces types de risques au sein de l’organisation. Des environnements de travail stressants, trop de tâches à accomplir avec des conditions physiques défavorables tels que les espaces de travail mal entretenus, mesures de sécurité inappropriées, bruit excessif, etc. Tous ces facteurs peuvent entrainer des problèmes psychosociaux comme le stress, l’anxiété et l’épuisement professionnel. Ce présent article examine les effets d’un mauvais environnement de travail comme facteur de détérioration de la santé et de bien-être psychosocial des salariés. La question qui se pose : comment l’amélioration des conditions de vie au travail peut-elle contribuer à réduire les RPS en entreprise ? Pour y répondre, une expérience incluant la distribution d’un questionnaire a été conduite, adressée aux cent-cinquante employés travaillant dans des entreprises industrielles région de Larache, Maroc. Les réponses collectées montrent que la santé psychosociale de plus de quatre-vingt pourcent des enquêtés est impactée directement par les conditions de vie au travail. Ces résultats indiquent qu’une bonne gestion sociétale responsable de l’espace professionnel est nécessaire afin d’améliorer le bien-être des collaborateurs et de réduire les RPS au sein des organisations.

Abstract:

Landslides are one of the natural hazards that many countries around the world are facing. In Morocco, the Rif regions are the most affected by these phenomena. Each year they cause enormous damage to the road network and infrastructure, especially in our study region, the province of Larache.The study region is subject to several opening up and road construction projects, which is why it is necessary to predict and identify the most vulnerable areas beforehand, in order to propose measures and techniques which are adequate for protection and reinforcement.The main goal of this study is to develop a susceptibility map to ground movements using a multi-criteria spatial assessment approach, and in order to reduce subjectivity, we have used a method for analyzing such complex decisions, which is the analytic hierarchy process (AHP) implemented in the geographic information system (GIS). Seven factors have been considered as conditioning factors in the occurrence of landslides, which are: lithology, fracturing density, slope, aspect, land use, density of the hydrographic network, and altitude. To verify the results obtained, we performed a correlation analysis of ground movements, already inventoried and verified in the field, with the susceptibility classes that were calculated. This analysis is accompanied by a statistical study.

Abstract:

Slide lands (Lands mass movements) are among the natural risks that Morocco faces in the Rifaines regions in particular. They generally constitute small-scale, punctual phenomena. But their diversity and frequency are nevertheless responsible for significant and costly damages and injuries. To deal with this problem, the study of field instabilities must take into account that: ithe ground movements must be taken in a context of the overall dynamics of the watershed, ii-the choice of more objective methods, which is not based on the very subjective opinion of the expert; iii-the choice of an adapted approach to the scale of work. In this article, we used the evidence theory "WofE" to evaluate the sensibility of landslide in the El Quola area. This method is based on the analysis of the relationships between landslides that occurred in the past (the so-called modelable variable Vm) and the spatial distribution of some predictive parameters of instability (Vp). The result obtained is a landslide susceptibility map that is the result of multi-disciplinary and multi-temporal data. This method has been described as one of the most performing by several authors; however, it requires a conditional independence between the different predictive factors. The quality of the performances was evaluated with success curves.

Abstract:

Many coastal aquifers have experienced seawater intrusion (SWI) into fresh groundwater aquifers. The principal causes of SWI include over-pumping and events such as climate change (CC) and rising sea levels. In northern Morocco, the Rmel-Oulad Ogbane coastal aquifer (ROOCA) supplies high-quality groundwater for drinking water and agriculture. This favorable situation has led to increased pumping, resulting in environmental challenges such as dropping water table and SWI. Furthermore, the climate has resulted in less recharge, with an estimated annual precipitation of 602 mm and an average temperature of 18.5 °C. The goal of this study is to determine how CC, over-pumping, and sea-level rise (SLR) affect SWI. Computational groundwater and solute transport models are used to simulate the spatial and temporal evolution of hydraulic heads and groundwater solute concentrations. The calibration is based on steady and transient groundwater levels from 1962 to 2040. SWI simulations show that the NW sector of the coastal area would be polluted, with the toe reaching 5.2 km inland with a significant salinity (15–25 g/L). To protect the fresh water in the reservoir from SWI, enhanced groundwater development and management approaches for this aquifer are required, such as artificial recharge from surface water.

Abstract:

The study area of Rmel-O. Ogbane aquifer, located in the north of Morocco, currently faces major water challenges related to the sustainable management of water resources. Climate change and Sea-Level-Rise can increase the risks and costs of water resources management and impact water resources' quantity and quality. Hence, for planning and management, an integrated approach is developed for linking climate models and groundwater models to investigate future impacts of climate change on groundwater resources. Climate projections show an increase in temperature of about 0.45 °C and a reduction in precipitation of 16.7% for 2016-2050. Simulations of seawater intrusion corresponding to various combinations of groundwater extraction predicted climate change and sea-level-rise show that the area will be contaminated on the NW sector of the coastal part. The toe would reach about 5.2 km inland and intrude on high salinity (15–25g/l). Beyond these zones, the contamination of the aquifer will be limited. Moreover, these results were confirmed by the application of the GALDIT method. They reveal that the fringe littoral areas of the aquifer are the most affected by seawater intrusion, with a high risk in the north-western part of the study area.

Abstract:

The subgenus Amblypteraca Mas-Peinado, Buckley, Ruiz & García-París, 2018 of Pimelia Fabricius, 1775, is restricted to the southern Iberian Peninsula and western Maghreb (northern and western Morocco). The distribution of Amblypteraca throughout the African-European edges overlaps largely with the geographic range of the subgenus Amblyptera, which is sister to the clade grouping subgenera Amblypteraca and Ecphoroma Solier, 1836. Delimiting species boundaries in the speciose genus Pimelia is often challenging, and the taxonomic status of some groups within the aforementioned subgenera is still a matter of debate. Here, we aim to stabilize some of the available names in Amblypteraca, and to correct some previous misidentifications. For that purpose, we discuss the composition and taxonomic structure within Amblypteraca by (i) assessing the phylogenetic congruence between mitochondrial and nuclear markers, and (ii) examining external morphological traits in 568 Amblypteraca specimens under the light of the phylogenetic hypotheses proposed here. Based on our results, Amblypteraca consists of three species: P. rotundipennis Kraatz, 1865, P. fairmairii Kraatz, 1865 and P. chrysomeloides Pallas, 1781. Both molecular and morphological data revealed four lineages within P. chrysomeloides: P. chrysomeloides chrysomeloides, distributed on both sides of the Strait of Gibraltar; P. chrysomeloides fornicata Herbst, 1799 from Portugal (Troia region); P. chrysomeloides bathyglypta Antoine, 1949, restricted to a narrow strip between Larache and Arbaoua (northern atlantic Moroccan coast), and P. chrysomeloides subris Koch, 1941 from Kenitra-La Mamora forest (Morocco). We designate a neotype of Tenebrio chrysomeloides Pallas, 1781 and propose the synonymy of P. chrysomeloides (Pallas, 1781) = P. obesa Solier, 1836 syn. n. Pimelia tristis Haag-Rutenberg, 1875, previously misidentified and included in Amblypteraca, is now transferred back to Amblyptera. Further studies with ad hoc sampling designs and analytical tools would be in need to delimit the exact geographic ranges of these taxa, and to analyse the patterns of diversity within and among species and subspecies.

Abstract:

Stevia rebaudiana is a perennial shrub belonging to the Asteraceae family. Recently, it has been introduced to Morocco from its native Paraguay; its molecules have a sweetening power that is about 300 times sweeter than sucrose. This characteristic makes of this plant a considerable natural noncalorific sweetener in case of hypoglycemic or low carbohydrate diet. This important interest has prompted us to make further studies on this plant. The objective of this work is to show the value of Stevia rebaudiana grown in the Larache region of Morocco by the chemical characterization and evaluation of the antioxidant activity of its extracts. A phytochemical screening was carried out to highlight the qualitative composition of secondary metabolites. This analysis showed the presence of flavonoids, tannins, oses and holosides, sterols, triterpenes, and free anthraquinones. However, the absence of alkaloids and reducing compounds has been observed. In addition, extraction of the total polyphenols was carried out by maceration using a 70% methanol–water mixture. The yield is of the order of 28.6%. Subsequently, fractionation of the crude extract was carried out by successively using three organic solvents of different polarities: chloroform, ethyl acetate, and n-butanol. Polyphenol dosage with Folin-Ciocalteu’s reagent showed that ethyl acetate fraction is richer in phenolic compounds (26.4%) than the other fractions. Flavonoids dosage with aluminum trichloride showed the richness of this plant in these compounds. The antioxidant activity of different fractions was evaluated by 2,2-diphenyl-1-picrylhydrazyl-free radical scavenging method and ferric reducing/antioxidant power method; the values of the 50% inhibitory concentrations (IC50) were determined graphically. It is equal to 0.32 mg/ml for the ethyl acetate fraction, compared to 0.08 mg/ml for the ascorbic acid used as a reference. In this study, we have shown that Stevia rebaudiana is very rich in phenolic compounds and possesses a very important antioxidant power.

Abstract:

Background. Human leishmaniasis, both visceral and cutaneous, has been reported in Morocco for centuries and constitutes a serious public health problem. However, the evolution of this pathology depends on several factors such as ecological, socioeconomic, and climatic conditions. The risk study of the affected foci is of great value for the control and surveillance of this endemic disease, especially in the provinces where Leishmania infantum predominates. Methods. This study concerned nine provinces located in the extreme and central north of Morocco (Taounate, Taza, Chefchaouen, Al Hoceima, Larache, Tétouane, Tanger-Assilah, M’diq-Fnideq, and Fahs-Anjra Provinces). In this work, leishmaniasis cases (VL and CL) were subjected to an epidemiological study which was performed using a linear regression model to identify the impact as well as the interaction between all predictor variables on the distribution of leishmaniasis in this region. Results. During the period 1997–2018, a total of 6 128 cases of VL and CL were recorded in the study area. Our results showed that among demographic factors studied, urbanization showed significance for both cutaneous and visceral forms (P<0.05). Regarding the environmental factors, the humidity and the altitude were significant for both CL and VL (P<0.05), while the temperature and the normalized difference vegetation index (NDVI) showed a significance only for VL. Moreover, trends in season of occurrence revealed that wet season (October to April) had a higher incidence of leishmaniasis compared to the dry season (May to September) specifically for CL. As for socioeconomic factors, poverty was the only factor that influences the spread of VL. Finally, the distance from endemic foci showed significance for both VL and LC (P<0.05). Conclusion. Our study revealed that the risk factor associated with cutaneous and visceral leishmaniasis in northern Morocco could help in the establishment of a prediction program.
