This study critically examines the structure, mechanisms, and enduring relevance of character education embedded in the indigenous knowledge systems of the Greater Horn of Africa. Pre-colonial African societies upheld sophisticated educational frameworks that emphasized holistic moral formation and communal character development, values that continue to influence rural communities today. Drawing on an integrative literature review, the paper identifies preparationism, functionalism, and communalism as core philosophical foundations shaping these systems. Moral and civic values were cultivated through informal, lifelong learning, guided by the collaborative roles of the home and community in fostering respect, responsibility, and social cohesion. Central pedagogical instruments included initiation rites, which provided structured moral instruction, and oral literature, which transmitted ethical reasoning and cultural wisdom. The findings underscore the continued relevance of indigenous character education in addressing contemporary societal challenges and advocate for Decolonizing the Mind as a pathway to revitalizing these traditions. The study concludes that reformed rites of passage, when purged of harmful elements, preserve cultural identity and strengthen communal ethics, offering a sustainable model for moral and civic education in modern Horn of African contexts.

Background/Objectives: Despite their ecological significance, DNA barcoding data for African rainforest Orthoptera remain underrepresented globally, limiting progress in species discovery, biodiversity assessment, and conservation. This study aimed to generate molecular data for morphologically identified Serpusia Karsch, 1891 species to evaluate their taxonomic status. Methods: Specimens were collected from multiple sites in Cameroon and analyzed using DNA barcoding with COI-5P and 16S rDNA markers. Species delimitation was performed with Automatic Barcode Gap Discovery, and phylogenetic relationships were inferred using Maximum Likelihood and Bayesian Inference. Additionally, external morphology and the male phallic complex were examined. Results: Molecular analyses delineated 19 MOTUs, five corresponding to Serpusia opacula, seven to Serpusia succursor and the remainder to outgroups. Similarity-based assignments matched these MOTUs to 19 BINs. Phylogenetic reconstruction revealed S. opacula and S. succursor as two genetically distinct clades, with the S. opacula group more closely related to Aresceutica Karsch, 1896 than to the S. succursor group. Accordingly, we established a new genus, Paraserpusia gen. nov., to accommodate S. succursor. Within the S. opacula group, five species are recognized: one previously described (S. opacula) and four new species (S. kennei sp. nov., S. missoupi sp. nov., S. seinoi sp. nov., and S. verhaaghi sp. nov.). The former S. succursor, now Paraserpusia succursor, is divided into six well-supported lineages, five of which are formally described here (P. hoeferi sp. nov., P. husemanni sp. nov., P. kekeunoui sp. nov., P. tamessei sp. nov., and P. tindoi sp. nov.). A haplotype network based on COI-5P sequences corroborates three major clades corresponding to the S. opacula group, the S. succursor group, and Aresceutica. Diagnostic morphological differences between Serpusia and Paraserpusia are consistently supported across characters. Conclusions: This integrative approach reveals substantial hidden diversity within Serpusia and highlights the importance of combining molecular and morphological data to uncover and formally describe previously overlooked taxa.

Segmentary lineage theory fell out of favor in cultural anthropology during the 1980s. However, the core ideas of segmentary lineage have continued to shape political mobilization as well as political analysis in Africa long after the theory’s supposed death. This article analyzes how and why the framework of segmentary lineage has endured as a potent means of describing and experiencing politics in the Somali-inhabited Horn of Africa. It theorizes Somali clanship, a classic example of a “pure” segmentary lineage structure, as a framework for managing the near-term future rather than as an objective description of existing social structures. We show how segmentary lineage has been politicized during the colonial and postcolonial eras as a tool for pre-emptive action by governments. We link this broader dynamic of politicization to the functions of clanship in everyday life as a mode of anticipating other people’s likely behavior based on clan-framed narratives about the past. Based on archival research, ethnographic fieldwork, and analysis of media and social media, we argue that Somali clanship operates in politics less as a network of shared interests or mobilization based on anticipated collective gains, and more as a framework for anticipating and attempting to pre-empt other people’s likely behavior.

Genomics plays a crucial role in addressing health disparities, yet most studies rely on the hg38 linear reference genome, limiting the potential of pangenomic approaches, particularly for underrepresented populations. In this study, we focus on characterising East African populations, particularly Somalis, by constructing a variation graph using Mozabites from the Human Genome Diversity Project (HGDP) given their ancestral affinity with Somalis. We evaluated the effectiveness of this graph-based reference in estimating effective population sizes (Ne) in Bedouins compared to the hg38 reference and examined its impact on allele frequencies and genome-wide association studies (GWAS). Applying a coalescent model to the graph-based reference produced a Ne estimate of approximately 17 for the Bedouin population, which was significantly lower than the estimate from the hg38 reference (approximately 79,000). Only the graph-based estimate fell within the 95% confidence interval in simulations, indicating improved accuracy. Moreover, graph variants exhibited significantly lower allele frequencies (p-value < 2.2 × 10−16), suggesting potential effects on the interpretation and power of GWAS. Notably, GWAS variants specific to Bedouins derived from the graph showed lower frequencies (p = 0.023) than those obtained from the linear reference. These findings suggest that a pangenomic approach, informed by populations with ancestral affinities such as the Mozabites, provides more accurate estimates of Ne and allele frequencies. This highlights the importance of pangenomic strategies to better capture genetic diversity in underrepresented populations, a critical step towards improving population genetics studies, personalised medicine, and equitable healthcare.

This paper includes a review of the Palaearctic and Oriental species of the genus Lichenophanes Lesne, 1899. It contains a description of the new species, Lichenophanes juxtaorientalis n. sp., which occurs in Cyprus and Crete. A new subspecies, Lichenophanes varius turanicus n. subsp.—occurring in Crete, Cyprus, and the Middle East—was separated from the species Lichenophanes varius (Illiger) and described. Moreover, this paper characterizes L. carinatus (Lewis) n. stat., which had been treated as a synonym of L. carinipennis (Lewis). Two maps present the geographic distribution of particular species, and the final part of this paper contains keys to identify them. Full article

In the Republic of Djibouti (Horn of Africa), fractured volcanic aquifers serve as the primary water resource. The country’s climatic characteristics (arid climate, average rainfall of 140 mm/year, and absence of surface water) have led to intensive groundwater exploitation to meet increasing water demands. This study focuses on the Dalha basalts aquifer in the Dikhil region. The Dikhil region, located in the southwest of Djibouti and bordering Ethiopia, spans 7200 km2. Its population is estimated at 112,000 inhabitants. The Dalha aquifer is intensively exploited to supply the region and its capital, the city of Dikhil (35,000 inhabitants). The primary objective of this work is to assess the current resources of this aquifer using numerical modeling and its capacity to meet future water demands under the impact of climate change. The RCP 2.6 (Representative Concentration Pathway) was used to simulate the climate scenario up to 2100. Superficial recharge is estimated at 3.86 × 106 m3/year. The current wellfield abstraction amounts to 2.34 × 106 m3/year, accounting for 60% of the aquifer’s recharge. The simulation under RCP 2.6 indicates a declining trend in the water table. These findings highlight the fragile state of the Dalha aquifer, which is critical for the socioeconomic stability of the region. Given its current vulnerability, any increase in exploitation is unsustainable, despite the growing water demand in the Dikhil region. To tackle this challenge, we recommend conducting further studies to deepen the understanding of this system and implementing a real-time monitoring network to track aquifer changes. Full article

Somaliland, located in the Horn of Africa, has been increasingly vulnerable to recurring droughts over the past years, severely affecting its agricultural productivity, water resources, and overall resilience. Despite the rising frequency of these natural disasters, there is limited research on the factors influencing residents’ preparedness, which hinders effective disaster management efforts. The purpose of this study was to examine factors that influence the perceived effectiveness of Somaliland residents towards drought preparedness by utilizing an extended Protection Motivation Theory (PMT) approach. The latent variables that were considered in this study were Government Intervention, Drought Awareness, Environmental Awareness, Coping Appraisal, Threat Appraisal, Behavioral Intention, and Perceived Effectiveness. Two hundred fifty-four (254) people living in Somaliland from all regional areas willingly responded to the survey questions by utilizing a snowball sampling method. Partial Least Square-Structural Equation Modeling (PLS-SEM) showed that drought awareness and environmental awareness had significant effects on threat appraisal. In addition, environmental awareness also had a significant positive effect on coping appraisal. Finally, threat appraisal and coping appraisal had significant effects on behavioral intention, which subsequently led to perceived effectiveness. This study addresses a gap in academic research and disaster preparedness efforts in Somaliland by providing insights into the theoretical framework that can enhance the country’s preparedness for drought and other natural hazards.

Systematic studies on Late Islamic cemeteries that integrate architectural, ritual, and biological aspects remain relatively rare, particularly in Islamic countries or regions with an active Muslim presence. Typically, available research focuses more on epigraphic and artistic features. Since 2018, excavations at the Cathedral and surveys in the ruins of the city of Adulis (Massawa, Eritrea) have uncovered 326 Muslim graves: six dating to the 15th and 18th centuries CE and 320 attributed to the mid-19th to the early 20th century CE. These discoveries have enabled, for the first time in Eritrea, a detailed scientific study of the biological characteristics of the human remains, the funerary architecture, and the burial rites of Muslim communities from the 15th to the early 20th century. The skeletal remains were analyzed through taphonomic and anthropological studies. The graves were categorized into various typologies based on their structural features, while evidence of funerary rituals was documented as indicative elements of the burial practices adopted. These findings were further enriched by ethnographic sources and collaborative work with local communities, who acted as custodians of the historical memory and traditions of the region. The results provide insights into a historical period of Eritrea that is otherwise poorly documented. More broadly, they contribute to the understanding of the history of the Horn of Africa, a region with limited data from funerary and archaeological contexts. The Muslim cemeteries of Adulis represent the most extensively investigated Muslim burial site in recent years, providing critical insights into the historical Muslim presence in the region. These findings also allow researchers to hypothesize the succession of various communities that chose Adulis as a central location for interring their deceased, reflecting its enduring significance as a focal point for cultural and ritual practices across different periods.

The threat to world food security posed by drought is ever increasing. Tef [Eragrostis tef (Zucc.) Trotter] is an allotetraploid cereal crop that is a staple food for a large population in the Horn of Africa. While the grain of tef provides quality food for humans, its straw is the most palatable and nutritious feed for livestock. In addition, the tef plant is resilient to several biotic and abiotic stresses, especially to drought, making it an ideal candidate to study the molecular mechanisms conferring these properties. The transcriptome expression of tef leaf collected from plants grown under drought conditions was profiled using RNA-Seq and key genes were verified using RT-qPCR. This study revealed that tef exhibits a complex molecular network involving membrane receptors and transcription factors that regulate drought responses. We identified target genes related to hormones like ABA, auxin, and brassinosteroids and genes involved in antioxidant activity. The findings were compared to physiological measurements such as changes in stomatal conductance and contents of proline, chlorophyll and carotenoid. The insights gained from this work could play vital role in enhancing drought tolerance in other economically important cereals such as maize and rice. Full article

Tuberculosis (TB) is the second-most prevalent cause of mortality resulting from infectious diseases worldwide. It is caused by bacteria belonging to the Mycobacterium tuberculosis complex (MTBC). In Israel, TB incidence is low, acknowledged by the WHO as being in a pre-elimination phase. Most cases occur among immigrants from high TB incidence regions like the Horn of Africa and the former Soviet Union (FSU), with occasional outbreaks. The outbreak described in this report occurred between 2018 and 2024, increasing the incidence rate of TB in the region. Control of this outbreak posed challenges due to factors including a diverse population (including Ethiopian immigrants, Israeli-born citizens, and immigrants from other countries), economic and social barriers, and hesitancy to disclose information. The unique multidisciplinary team formed to address these challenges, involving the local TB clinic, district health ministry, health maintenance organization (HMO) infectious disease consultant, neighborhood clinic, and National Mycobacterium Reference Laboratory (NMRL), achieved effective treatment and containment. Whole genome sequencing (WGS) proved pivotal in unraveling patient connections during the outbreak. It pinpointed those patients overlooked in initial field investigations, established connections between patients across different health departments, and uncovered the existence of two distinct clusters with separate transmission chains within the same neighborhood. This study underscores collaborative efforts across sectors that successfully contained a challenging outbreak. Full article

Globally, there has been little growth in vaccination coverage, with countries in the Horn of Africa having the lowest vaccination rates. This study investigated factors associated with vaccination status among children under five years old in Somaliland. The 2020 Somaliland Demographic and Health Survey surveyed women aged 15–49 years from randomly selected households. This multilevel analysis included 2673 primary caregivers of children under five. Only 34% of children were ever vaccinated. Childhood vaccination coverage was positively associated with high-budget regions, high healthcare facility density, and children older than 23 months. Vaccination coverage was greater for urban and rural residents than for nomadic people. Children whose mothers could read part of one sentence or one complete sentence were more likely to be vaccinated than illiterate mothers. Children whose mothers received antenatal care (ANC) once, two to three times, or four times or more were more likely to be vaccinated than those whose mothers received no ANC. Childhood vaccination coverage in Somaliland is low. Promoting maternal ANC visits and increasing women’s literacy may enhance vaccination coverage. Funds should be allocated to areas with low resources, particularly for nomadic people, to boost vaccination uptake. Full article

The Horn of Africa has sensitive, arid ecosystems, with its vegetation commonly distressed by factors such as climate change, population increase, unstable water resources, and rarely enforced land use management practices. These factors make countries such as Djibouti highly variable locations for the growth of vegetation and agricultural products, and these countries are becoming more vulnerable to food insecurity as the climate warms. The rapid growth of satellite and digital image processing technology over the last five decades has improved our ability to track long-term agricultural and vegetation changes. Data cubes are a newer approach to managing satellite imagery and studying temporal patterns. Here, we use the cloud-based Digital Earth Africa, Open Data Cube to analyze 30 years of Landsat imagery and orthomosaics. We analyze long-term trends in vegetation dynamics by comparing annual fractional cover metrics (photosynthetic vegetation, non-photosynthetic vegetation, and bare ground) to the Normalized Difference Vegetation Index. Investigating Djibouti-wide and regional vegetation trends, we provide a comparison of trends between districts and highlight a primary agricultural region in the southeast as a detailed example of vegetation change. The results of the Sen’s slope and Mann–Kendall regression analyses of the data cube suggest a significant decline in vegetation (p = 0.00002), equating to a loss of ~0.09 km2 of arable land per year (roughly 2.7 km2 over the 30-year period). Overall, decreases in photosynthetic vegetation and increases in both non-photosynthetic vegetation and bare soil areas indicate that the region is becoming more arid and that land cover is responding to this trend.

Invasive alien species (IAS) are a major biosecurity threat affecting globalisation and the international trade of agricultural products and natural ecosystems. In recent decades, for example, field crop and postharvest grain insect pests have independently accounted for a significant decline in food quantity and quality. Nevertheless, how their interaction and cumulative effects along the ever-evolving field production to postharvest continuum contribute towards food insecurity remain scant in the literature. To address this within the context of Africa, we focus on the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), and the larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), two of the most important field and postharvest IAS, respectively, that have invaded Africa. Both insect pests have shown high invasion success, managing to establish themselves in >50% of the African continent within a decade post-introduction. The successive and summative nature of field and postharvest damage by invasive insect pests on the same crop along its value chain results in exacerbated food losses. This systematic review assesses the drivers, impacts and management of the fall armyworm and larger grain borer and their effects on food systems in Africa. Interrogating these issues is important in early warning systems, holistic management of IAS, maintenance of integral food systems in Africa and the development of effective management strategies.

In the global migration crisis, one of the challenges in the effort to identify deceased migrants is establishing their region of origin, which facilitates the search for ante mortem data to be compared with the post mortem information. This pilot study explores the potential of using stable isotope analysis to distinguish between individuals coming from West Africa and the Horn of Africa. Six individuals (four of known origin and two of unknown origin) were sampled. δ13CVPDB(keratin), δ15NVPDB(keratin) and δ18OVSMOW(keratin) of hair were analysed using Elemental Analyzers coupled with Isotope Ratio Mass Spectrometry (IRMS). δ18OVSMOW(carbonate) and δ13CVPDB(carbonate) of bone were analysed using GasBench II with IRMS, while 87Sr/86Sr composition was determined in bone and dental enamel using laser ablation multi-collector inductively coupled plasma mass spectrometry. The stable isotope compositions of the individual from the Horn of Africa differed from the other individuals. The differences found between 87Sr/86Sr of enamel and bone and between δ18O and δ13C in bone and hair reflect changes in sources of food and water in accordance with regionally typical migration journeys. The analysis of multiple stable isotopes delivered promising results, allowing us to narrow down the region of origin of deceased migrants and corroborate the information about the migration journey.

Besides living as a free-ranging primate in the horn of Africa and the Arabian Peninsula, the hamadryas baboon has an important place in zoos and can be found in biomedical research centers worldwide. To be valuable as a non-human primate laboratory model for man, its anatomy should be portrayed in detail, allowing for the correct interpretation and translation of obtained research results. Reviewing the literature on the use of the baboon in biomedical research revealed that very limited anatomical works on this species are available. Anatomical atlases are incomplete, use archaic nomenclature and fail to provide high-definition color photographs. Therefore, the skeletons of two male hamadryas baboons were prepared by manually removing as much soft tissues as possible followed by maceration in warm water to which enzyme-containing washing powder was added. The bones were bleached with hydrogen peroxide and degreased by means of methylene chloride. Photographs of the various bones were taken, and the anatomical structures were identified using the latest version of the Nomina Anatomica Veterinaria. As such, the present article shows 31 annotated multipanel figures. The skeleton of the hamadryas baboon generally parallels the human skeleton, but some remarkable differences have been noticed. If these are taken into consideration when evaluating the results of experiments using the hamadryas baboon, justified conclusions can be drawn. Full article
