Athamanta L. is a small genus of the Apiaceae family, comprising only sixteen species and subspecies, which are distributed in the Canary Islands, Central Europe, and the Mediterranean basin. Background/Objectives: Since the time of Dioscurides, the species of this genus have been reported to have had several ethnopharmacological activities, and some of them are also used currently. Athamanta sicula L., growing in Italy, Tunisia, Algeria, and Morocco, is the only species of this genus present in Sicily. To further explore the phytochemical profile and biological properties of this species, the present study focused on the essential oil (EO) extracted from the aerial parts of wild A. sicula populations collected in central Sicily. Methods: The chemical composition of the EO, obtained by hydrodistillation, was determined by GC–MS analysis. The presence of myristicin was confirmed by isolation and by ¹H-NMR spectroscopic characterization. Results: The EO and its main constituents have been tested for possible antimicrobial properties against several bacterial strains, showing MIC values in the of 15–30 mg/mL range, and the mechanism of action was further investigated, revealing membrane-targeting effects consistent with outer membrane permeabilization. In addition, antibiofilm activity (with up to ~80% inhibition of biofilm formation at sub-MICs), antioxidant potential (demonstrating dose-dependent radical scavenging activity), and biocompatibility with eukaryotic cells were assessed to provide a comprehensive pharmacological profile of A. sicula EO. Specifically, the most abundant constituent was myristicin (62.2%), the principal representative of the phenylpropanoid class (64.4%). Hydrocarbon monoterpenes represented the second class of the EO (27.4%), with β-phellandrene (12.2%) as the main compound. Conclusions: Myristicin emerged as the key contributor to the antimicrobial and antibiofilm activity of the EO. The obtained results highlight the relevance of A. sicula EO as a myristicin-rich essential oil with notable in vitro biological activity. Full article

Contrary to states such as Egypt or Morocco, the Jordanian state could not rely on long-lasting Islamic tradition and institutions at its creation and was exposed to the religious influence of its neighbours. The regime had to “invent” a Jordanian religious tradition, making Jordan a particularly interesting case for the study of the development of Islamic policies—central to a regime that significantly relies on religious legitimacy. This contribution based on fieldwork in Amman dives into the nationalisation of the Islamic education of Jordanian imams and preachers as a component of official Islam. It argues that the nationalisation of higher Islamic education is a crucial element of state control over religion and is inscribed in the regional competition over religious influence as much as in international considerations. It contributes to improving our understanding of the entanglement of the domestic promotion of official Islam and regional fight for religious influence. Full article

Flooding is one of Africa’s most impactful natural disasters, significantly affecting human lives, infrastructure, and economies. This study examines the spatial and temporal distribution of historical flood events across the continent from 1927 to 2020, with a focus on fatalities, affected populations, and economic damage. Data from the Emergency Events Database (EM-DAT), the fifth generation of bias-corrected European Centre for Medium-Range Weather Forecasts Reanalysis (ERA5), and the Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) observational datasets were used to calculate extreme precipitation indices—Consecutive Wet Days (CWD), annual precipitation on very wet days (R95PTOT), and Annual Maximum Precipitation (AMP). Spatial analysis tools and the Mann–Kendall test were used to assess trends in flood occurrences, while Pearson correlation analysis identified key meteorological drivers across 16 African capital cities for 1981–2019. A flood frequency analysis was conducted using Weibull, Gamma, Lognormal, Gumbel, and Logistic probability distribution models to compute flood return periods for up to 100 years. Results reveal a significant upward trend with a slope above 0.50 floods per year in flood frequency and impact over the period, particularly in regions such as West Africa (Nigeria, Ghana), East Africa (Ethiopia, Kenya, Tanzania), North Africa (Algeria, Morocco), Central Africa (Angola, Democratic Republic of Congo), and Southern Africa (Mozambique, Malawi, South Africa). Positive trends (at 99% significance level with slopes ranging between 0.50 and 0.60 floods per year) were observed in flood-related fatalities, affected populations, and economic damage across Regional Economic Communities (RECs), individual countries, and cities of Africa. The CWD, R95PTOT, and AMP indices emerged as reliable predictors of flood events, while non-stationary return periods exhibited low uncertainties for events within 20 years. These findings underscore the urgency of implementing robust flood disaster management strategies, enhancing flood forecasting systems, and designing resilient infrastructure to mitigate growing flood risks in Africa’s rapidly changing climate.

Amid growing sustainability and ethical concerns, digital innovation increasingly requires integrating social, environmental, and governance responsibility into technological development. However, little is known about how organizations in emerging economies—particularly in North Africa—operationalize these principles in practice. This study addresses this gap by exploring how institutional and economic actors in Morocco incorporate responsibility principles into their digital innovation strategies. Adopting an exploratory qualitative design, we conducted 27 semi-structured interviews with digital managers from public organizations (ministries, institutions, and local authorities) and private firms (technology companies, start-ups, and large corporations). The central research question guiding this study is: How do Moroccan organizations perceive and implement the principles of responsible digital innovation (RDI)? Data were analyzed using NVivo 14 software through thematic coding and triangulated with policy documents to enhance validity. The results reveal growing awareness of digital sustainability issues—particularly energy efficiency, accessibility, and data protection—yet the degree of responsible practice varies by sector, firm size, and regulatory environment. Key obstacles include limited expertise, absence of ethical performance metrics, and competitive pressures constraining investment in RDI. Conversely, ethical charters, frugal design, and stakeholder engagement emerge as key drivers. The study concludes that embedding responsibility in digital innovation requires shared governance frameworks, supportive public policies, and cross-sector collaboration to promote inclusive and sustainable technological progress. While context-specific, this research opens avenues for comparative and quantitative studies on RDI across emerging economies. Full article

This article examines the development of Islamic education in Islamic primary schools in the Netherlands from 1988 to 2025. Since the early 1970s, the Muslim population in the Netherlands has grown significantly—initially due to labor migrants from Turkey and Morocco, and later as a result of asylum seekers from countries such as Somalia, Iraq, and Syria. The desire to practice and pass on their faith led to the establishment of mosques, educational centers, boarding schools, and eventually Islamic primary schools. In 1987, some of the founders of Islamic primary schools aspired to establish institutions similar to Madrasas, focusing heavily on Islamic instruction such as Qur’an recitation and Hadith studies. However, these ambitions could not be realized due to funding requirements. Others were inspired by the Imam Hatip schools in Turkey, which offer religious subjects such as Qur’an, Hadith, and Sira (the life of the Prophet Muhammad) alongside the national curriculum. Ultimately, a Dutch model of Islamic education emerged—partly influenced by the Imam Hatip concept, yet possessing a distinct identity. This study investigates how Islamic education has evolved in practice through semi-structured interviews, school observations, document analysis, and a national survey of religion teachers. The findings indicate that the desire to provide Islamic religious education was the primary motive behind the founding of the first Islamic primary school in 1988. Since then, this objective has remained central to school boards and parents alike. Religious education has progressed from fragmented teaching materials rooted in Arabic and Turkish contexts to coherent, Dutch-language curricula. By 2025, the teaching materials of Worden wie je bent (“Becoming Who You Are”) and the Amana have become dominant. Instruction encompasses not only religious knowledge and Qur’an recitation but also social-emotional development, citizenship, and sexuality education within an Islamic framework. Full article

Soil salinity severely constrains agricultural productivity and soil health, particularly in arid and semi-arid regions. Conventional salinity assessment methods are labor-intensive, time-consuming, and spatially limited. This study developed a data-scarce workflow integrating proximal sensing (EM38-MK2), very high-resolution multispectral imagery, and machine learning to map soil salinity at field scale in the semi-arid Sehb El Masjoune area, central Morocco. A total of 26 soil samples were analyzed for Electrical Conductivity (EC), and 500 Apparent Electrical Conductivity (ECa) measurements were collected and calibrated using the field samples. Spectral and topographic covariates derived from Unmanned Aerial Vehicle (UAV) and PlanetScope imagery supported model training using Partial Least Squares Regression (PLSR), Support Vector Regression (SVR), Random Forest (RF), and a Stacked Ensemble Learning Model (ELM). Regression Kriging (RK) was applied to model residuals to improve spatial prediction. ELM achieved the highest accuracy (R² = 0.87, RMSE ≈ 4.15), followed by RF, which effectively captured nonlinear spatial patterns. RK improved PLSR accuracy (by 11.1% for PlanetScope, 13.8% for UAV) but offered limited gains for RF, SVR, and ELM. SHAP analysis identified topographic covariates as the most influential predictors. Both UAV and PlanetScope delineated similar saline–sodic zones. The study demonstrates the following: (1) a scalable, data-efficient workflow for salinity mapping; (2) model and RK performance depend more on algorithmic design than sensor type; (3) interpretable ML and spatial modeling enhance understanding of salinity processes in semi-arid systems.

Understanding why households choose particular urban neighborhoods requires bridging traditional rational-choice explanations with emerging evidence on cognitive, social, and informational influences. This study investigates how territorial intelligence (TI)—defined as the availability and use of spatial data, planning information, and participatory knowledge platforms—interacts with behavioral factors to shape residential relocation decisions. Employing an explanatory sequential mixed-methods design, we surveyed 356 recent movers in Casablanca, Morocco, and conducted 20 follow-up semi-structured interviews. Quantitative analysis shows that each additional consulted data source increased the odds of selecting a central, transit-rich location by 45 %, while prior awareness of development plans raised those odds by 60 %, controlling for income, tenure, affordability, dwelling attributes, and socio-demographics. Data use also predicted higher post-move satisfaction, particularly when individual housing preferences aligned with chosen locations. Qualitative findings reveal that residents view territorial data as a tool for “future-proofing” but also experience information overload, leading some to revert to heuristics or social advice. The interplay of rational cost–benefit logic, bounded cognitive processing, and TI-mediated knowledge underscores the need for planning strategies that combine economic fundamentals with behaviorally informed data provision. By integrating micro-level decision evidence with the territorial intelligence framework, the study offers practical guidance for urban planners aiming to nudge residential choices toward more sustainable, policy-consistent outcomes.

Plants inhabiting arid regions often harbor microbial communities that contribute to their resilience under extreme conditions. Yet, the genomic diversity and functional potential of bacterial endophytes associated with desert-adapted plants, particularly in Africa, remain largely unexplored. In this study, we investigated Microbacterium endophytes from the xerophytic cucurbit Citrullus colocynthis L. (Cucurbitaceae), collected in a semi-arid environment in central Morocco. Using culture-based isolation, phenotypic characterization, and whole-genome sequencing, we analyzed three representative isolates from leaf and root tissues. Genome-based taxonomy combined with polyphasic analyses identified two novel species, Microbacterium xerophyticum sp. nov. and Microbacterium umsixpiens sp. nov., with genome sizes of approximately 4.0 Mb and 3.9 Mb, respectively. Functional annotation revealed traits consistent with endophytism in water-limited ecosystems, including oxidative and osmotic stress responses, metal homeostasis, and high-affinity phosphate uptake. Differences in siderophore acquisition and nitrogen metabolism suggest niche partitioning between the two species. These findings document two novel bacterial species from a medicinal plant native to arid ecosystems, broaden the known diversity of plant-associated Microbacterium, and provide region-specific genomic references with adaptive traits relevant to host resilience under arid conditions.

This study assesses and inventories agrodiversity within eleven representative oases of the pre-Saharan regions of Morocco, ecosystems that are particularly vulnerable to climate change and socio-economic pressures. The findings highlight the central role of fruit tree diversity in structuring and sustaining the resilience of oasis agroecosystems, complementing cereal and fodder crops. Special attention was given to the pomegranate (Punica granatum L.), a secondary but underutilized fruit species in Moroccan agriculture, which was found to hold a significant position in the surveyed oases. Farmer and community surveys identified five local denominations or varieties, including an original form known as “Guersmoum” or “Hamed,” distinguished by its spontaneous, non-cultivated character. This unique case exemplifies the remarkable coexistence between wild and domesticated forms, reflecting the complex dynamics between cultivated and wild biodiversity. The presence and use of this variety are closely linked to the production of a traditional local agri-food product, pomegranate molasses (“Amaghousse”), an artisanal know-how transmitted across generations and primarily preserved by women. The study documents several aspects of this practice, including processing techniques, yield ratios, and marketing channels, emphasizing both the economic and cultural significance of this local product. The discussion underscores the close interconnections between traditional knowledge, gendered practices, and the conservation of genetic diversity, showing how the promotion of local resources contributes not only to the preservation of agrodiversity but also to the maintenance of oasis cultural identities. Finally, the study highlights the broader implications of these findings for development initiatives, particularly through the recognition and promotion of distinctive local agri-food products, the integration of women in local conservation strategies, and the implementation of sustainable management approaches for fruit genetic resources.

Environmental education (EE) is central to achieving the Sustainable Development Goals (SDGs), particularly where inequalities constrain access to quality learning. Following PRISMA 2020, this review synthesizes 35 peer-reviewed studies and policy documents to examine Morocco’s EE policies and practices against global frameworks and post-pandemic challenges. A systematic search was conducted in Scopus, Web of Science, ERIC, ProQuest/EBSCO, Google Scholar, and national repositories (January 2000–December 2024; executed 15–17 March 2024). Findings show strong discursive alignment with SDG 4.7 and UNESCO’s ESD 2030 Roadmap but persistent implementation gaps: rural and peri-urban schools face resource shortages; teacher preparation for participatory, interdisciplinary approaches remains limited; and environmental clubs often rely on short-term projects without stable institutional support. The COVID-19 period exacerbated these pressures yet opened opportunities to integrate health–environment linkages, digital tools, and adaptive pedagogy. Equity reporting was limited (31% gender; 37% residence; 9% socio-economic status). Arabic-only records were identified (n = 42) and title/abstract-screened (n = 17) but excluded due to translation constraints (language bias). To advance transformative EE, we recommend prioritizing participatory, place-based teacher education; institutionalizing school clubs with light monitoring and baseline grants; targeting support to reduce territorial inequities; and developing an SDG-aligned national dashboard. Expanding longitudinal, quasi-experimental, and participatory designs is critical to strengthen causal claims and inform policy. Full article

Natural geogenic effects lead to alterations in soil heavy metal concentrations. This study assesses the presence of elevated trace-element concentrations in the Oued Irriri watershed in southeastern Morocco. ASTER satellite imagery, geochemical, and aeromagnetic data are combined to determine the origin of these anomalies. Processing of ASTER images delineated alteration zones coinciding with areas of high heavy metal anomalies by detecting hydrothermal alteration minerals, including muscovite, montmorillonite, illite, hematite, jarosite, chlorite, and epidote. Principal Component Analysis (PCA) of geochemical data distribution in soils enabled the characterization of variations in trace-element concentrations, the extraction of geochemical anomalies, and the identification of potential sources of contamination. Comparing satellite image processing results with geochemical analyses facilitated the production of a geogenic enrichment map. The study results indicate high enrichment levels of zinc, Molybdenum, and bismuth in the western basin, of purely lithological origin. Hydrothermal alteration surfaces intersect geochemical anomaly zones in the north and northeast, primarily showing the impact of fault rooting on the surface deposition of Cu, Ba, Hg, and Pb-rich deposits. This study developed a geogenic enrichment map indicating naturally affected areas, identifying potential risks to eco-environmental systems, and better preventing the effects of geogenic enrichment.

The mashrabiya is a key element that characterizes Islamic architecture, and in recent years it has been reintroduced into public building designs, partially due to its strong symbolic significance. Focusing on the application of mashrabiyas in historical public buildings, this work aims to contribute by examining the use of this architectural element in traditional Islamic public architecture. This area has received comparatively less attention in the existing literature, which predominantly focuses on residential applications. While the functions and applications of mashrabiyas in the residential context are well documented, their role within public structures remains less explored. This study investigates their functions in eight case studies from Egypt, Syria, Morocco, and India, spanning four public building types: mosques, Quranic schools, bimaristans, and caravanserais. The methodology considers the mashrabiya within four categories of public buildings in Islamic architecture across diverse geographical contexts, trying to understand possible unique characteristics in its form, material, and function. The choice of this method is based on the need to identify possible analogies or specific differences among the various examples of mashrabiya analyzed within their respective typologies. The results show that the mashrabiya in Islamic public buildings has transcended its functional aspects to hold a symbolic meaning in Islamic culture. Over the centuries, it has been a significant and constant presence in Islamic public buildings. The choice of materials—wood and stone—reflects geographical and technological influences; however, despite design variations, all refer to abstract geometric motifs central to Islamic decorative tradition.

The Maghreb region of North Africa, located at the intersection of the Palaearctic and Afrotropical zones, is a biodiversity hotspot for terrestrial and freshwater taxa, including the freshwater crab of genus Potamon Savigny, 1816. Recent molecular studies have suggested the presence of two distinct Potamon species in the region: Potamon algeriense Bott, 1967, and an as-yet undescribed taxon, Potamon sp. However, comprehensive data on their distribution, genetic structure, and conservation status are still lacking. In the present study, we integrate new field collections from Algeria and Morocco (2021–2023) with molecular analyses of mitochondrial (COI, ND1) and nuclear (28S rDNA) markers to assess species boundaries and genetic diversity within Potamon across the Maghreb. Phylogenetic reconstructions based on Maximum Likelihood and Bayesian Inference consistently support the presence of two well-differentiated Potamon lineages in the region, corresponding to P. algeriense in western and central Maghreb, and Potamon sp. in eastern Algeria and Tunisia. While Potamon sp. exhibits low intra-specific genetic variation, P. algeriense displays a deeply structured mitochondrial lineage composition, forming four geographically coherent subclades, each corresponding to distinct hydrological regions. In light of this, it would be advisable to revise the IUCN assessment to include both species and updated information on their distribution. Full article

This study evaluates the competitiveness and sustainable development prospects of French-speaking African countries by constructing a comprehensive framework integrating the TOPSIS method and adaptive LASSO algorithm. Using multivariate data from sources such as the World Bank, 30 indicators covering core, basic, and auxiliary competitiveness were selected to quantitatively analyze the competitiveness of 26 French-speaking African countries. Results show that their comprehensive competitiveness exhibits spatial patterns of “high in the north and south, low in the east and west” and “high in coastal areas, low in inland areas”. Algeria, Morocco, and six other countries demonstrate high competitiveness, while Central African countries generally show low competitiveness. The adaptive LASSO algorithm identifies three key influencing factors, including the proportion of R&D expenditure to GDP, high-tech exports, and total reserves, as well as five secondary key factors, including the number of patent applications and total number of domestic listed companies, revealing that scientific and technological investment, financial strength, and innovation transformation capabilities are core constraints. Based on these findings, sustainable development strategies are proposed, such as strengthening scientific and technological research and development and innovation transformation, optimizing financial reserves and capital markets, and promoting China–Africa collaborative cooperation, providing decision-making references for competitiveness improvement and regional cooperation of French-speaking African countries under the background of the “Belt and Road Initiative”.

The Ouarzazate Group in the Anti-Atlas Belt of southern Morocco, part of the West African Craton (WAC), is a significant Proterozoic lithostratigraphic unit formed during the late Ediacaran period. It includes extensive volcanic rocks associated with the early stages of Iapetus Ocean opening. Zircon U-Pb dating and geochemical analyses of the Oued Dar’a Caldera (ODC) volcanic succession in the Saghro Massif reveal two major eruptive cycles corresponding to the lower and upper Ouarzazate Group. The 1st cycle (588–563 Ma) includes pre- and syn-caldera volcanic succession characterized by basaltic andesite to rhyolitic rocks, formed in a volcanic arc setting through lithospheric mantle-derived mafic magmatism and crustal melting. A major caldera-forming eruption occurred approximately 571–562 Ma, with associated rhyolitic dyke swarms indicating a larger caldera extent than previously known. The 2nd cycle (561–543 Ma) features post-caldera bimodal volcanism, with tholeiitic basalts and intraplate felsic magmas, signaling a shift to continental flood basalts and silicic volcanic systems. The entire volcanic activity spans approximately 23–40 million years. This succession is linked to late Ediacaran intracontinental super-eruptions tied to orogenic collapse and continental extension, likely in association with the Central Iapetus Magmatic Province (CIMP), marking a significant transition in the geodynamic evolution of the WAC.
