Food safety concerns related to pesticide residues in fruits and vegetables have increased globally, particularly in regions where monitoring programs are scarce or inconsistent. This study provides the first multi-year evaluation of pesticide contamination and associated dietary risks in Cape Verde, an African island nation increasingly reliant on imported produce. A total of 570 samples of fruits and vegetables—both locally produced and imported—were collected from major markets across the country between 2017 and 2020 and analyzed using validated multiresidue methods based on gas chromatography coupled to Ion Trap mass spectrometry (GC-IT-MS/MS), and both gas and liquid chromatography coupled to triple quadrupole tandem mass spectrometry (GC-QqQ-MS/MS and LC-QqQ-MS/MS). Residues were detected in 63.9% of fruits and 13.2% of vegetables, with imported fruits showing the highest contamination levels and diversity of compounds. Although only one sample exceeded the maximum residue limits (MRLs) set by the European Union, 80 different active substances were quantified—many of them not authorized under the current EU pesticide residue legislation. Dietary exposure was estimated using median residue levels and real consumption data from the national nutrition survey (ENCAVE 2019), enabling a refined risk assessment based on actual consumption patterns. The cumulative hazard index for the adult population was 0.416, below the toxicological threshold of concern. However, when adjusted for children aged 6–11 years—taking into account body weight and relative consumption—the cumulative index approached 1.0, suggesting a potential health risk for this vulnerable group. A limited number of compounds, including omethoate, oxamyl, imazalil, and dithiocarbamates, accounted for most of the risk. Many are banned or heavily restricted in the EU, highlighting regulatory asymmetries in global food trade. These findings underscore the urgent need for strengthened residue monitoring in Cape Verde, particularly for imported products, and support the adoption of risk-based food safety policies that consider population-specific vulnerabilities and mixture effects. The methodological framework used here can serve as a model for other low-resource countries seeking to integrate analytical data with dietary exposure in a One Health context. Full article

In order to fulfil SDG 13—taking urgent action to combat climate change and its impact—SDG 2—ending hunger and poverty—and the African Union CAADP Strategy and Action Plan: 2026–2035, which’s goal is ending hunger and intensifying sustainable food production, agro-industrialisation, and trade, the resilience of commercial livestock farmers to agricultural droughts needs to be enhanced. Agricultural drought has affected the economies of many sub-Saharan African countries, including South Africa, and still poses a challenge to commercial livestock farming. This study identifies and determines the factors affecting commercial livestock farmers’ level of resilience to agricultural drought. Primary data from 123 commercial livestock farmers was used in a principal component analysis to estimate the agricultural drought resilience index as an outcome variable, and the probit model was used to determine the factors influencing the resilience of commercial livestock farmers in the Northern Cape Province of South Africa. This study provides a valuable contribution towards resilience-building strategies that are critical for sustaining commercial livestock farming in arid regions by developing a formula for calculating the Agricultural Drought Resilience Index for commercial livestock farmers, significantly contributing to the pool of knowledge. The results showed that 67% of commercial livestock farming households were not resilient to agricultural drought, while 33% were resilient. Reliance on sustainable natural water resources, participation in social networks, education, relative support, increasing livestock numbers, and income stability influence the resilience of commercial livestock farmers. It underscores the importance of multidimensional policy interventions to enhance farmer drought resilience through education and livelihood diversification. Full article

The Malabo Declaration commits African Union member states to eliminating hunger by 2025. Progress toward this target has been uneven and poorly understood. While some countries have recorded gains in non-hunger thematic areas such as finance, trade, resilience to climate variability, and governance and accountability mechanisms, the extent to which these improvements contribute to hunger reduction remains unclear. This study investigates whether performance in non-hunger areas, as measured through the Comprehensive Africa Agriculture Development Programme Biennial Review C-scores, is statistically associated with outcomes under Commitment 3, which focuses on hunger reduction. We used random effects panel regression model covering 55 African countries from 2017 to 2023, the analysis identifies five significant predictors: agricultural GDP and poverty reduction (PC 4.1), foreign private investment (PC 2.3), multi stakeholder coordination (PC 1.2), inclusive public–private partnerships (PC 4.2), and trade policies (PC 5.2). Investment in resilience (PC 6.2) and capacity for planning and monitoring (PC 7.1) showed marginal associations. Our findings suggest that institutional presence alone does not drive hunger outcomes. We reflect that what matters is the structure, inclusiveness, and functionality of these mechanisms, including whether investments reach food-insecure populations, coordination platforms influence decisions, and policies adapt to local conditions. This study concludes that some high-performing categories fail to deliver tangible hunger reduction benefits when implementation is fragmented or disconnected from context. These findings challenge how progress is currently measured and interpreted at the regional level. Finally, we reiterate that as the region prepares for the post-2025 agenda, future strategies must directly link agricultural transformation to hunger reduction through targeted interventions and accountable institutions.

This comparative case study interrogates how Zimbabwe’s independent press reported on ZANU-PF factionalism in the period from 2014 to 2017. It focuses on two dailies, Daily News and NewsDay. These were Zimbabwe’s only privately owned newspapers at the time. The other daily newspapers were The Herald and Chronicle, whose editorial was controlled by the Zimbabwe African National Union Patriotic Front (ZANU-PF) government of Robert Mugabe. Whereas scholarship on ZANU-PF factionalism and the press is still burgeoning, little has been studied about how the independent press reported on Mugabe’s succession. The study is guided by framing theory. Data were gathered through archival research and in-depth face-to-face interviews with purposively selected journalists at Daily News and NewsDay who published stories on Mugabe’s succession. Findings reveal that rival ZANU-PF factions captured bribed journalists and influenced how they reported on Mugabe’s succession. Journalism grew “factionalized” (biased) as reporters became agents of the rival ZANU-PF factions. This disabled the newspapers from playing their informative and educative roles effectively. The factionalized reports left Zimbabweans ill-informed about developments in the governing party. Full article

This paper presents findings from the LEOPARD project, part of the LEAP-RE program, a joint European Union (EU) and African Union initiative to advance renewable energy solutions. The study employs a simulation-based approach to optimize solar-integrated microgrid configurations for rural electrification. The project deployed a solar-integrated pilot microgrid at the Songhai agroecological center in Benin to address key challenges, including load profile estimation, energy balancing, and diesel dependency reduction. A hybrid methodology integrating predictive modeling, real-time solar and weather data analysis, and performance simulations was employed, leading to a 65% reduction in diesel reliance and an LCOE of EUR 0.47/kWh. Quality control measures, including compliance with IEC 61215 and IEC 62485-2 standards, ensured system reliability under extreme conditions. Over 150 days, the system consistently supplied energy, preventing 10.16 tons of ${CO}_2$ emissions. Beyond the Benin pilot, the project conducted feasibility assessments in Senegal to evaluate microgrid replicability across different socio-economic and environmental conditions. These analyses highlight the scalability potential and the economic viability of expanding solar microgrids in rural areas. Additionally, this research explores innovative business models and real-time diagnostics to enhance microgrid sustainability. By providing a replicable framework, it promotes long-term energy access and regional adaptability. With a focus on community involvement and capacity building, this study supports efforts to reduce energy poverty, strengthen European–African collaboration, and advance the global clean energy agenda.

Plastic waste poses a significant challenge in Africa and around the world, with its volume continuing to increase at an alarming rate. In Africa, an estimated 25–33% of daily waste is made up of plastic, posing a threat to the environment, marine life, and human health. One potential solution to this problem is waste-to-energy recycling, such as pyrolysis, which involves the conversion of waste materials into oil, char, and non-condensable gasses through a thermochemical process in the absence of oxygen. Given the abundance of waste in Africa and the continent’s energy challenges, pyrolysis offers a sustainable solution. This review delves into the concept of pyrolysis, its products, thermodynamics, and endothermic kinetics, presenting it as a promising way to address the plastic waste problem in Africa. Despite the African Union’s goal to recycle plastic waste, the continent faces significant barriers in achieving this target, including infrastructural, economic, and social difficulties. It is crucial to implement sustainable strategies for managing plastic waste in Africa to mitigate environmental degradation and promote a cleaner and healthier living environment. Pyrolysis technology is highlighted as a viable solution for plastic waste management, as it can convert plastic waste into valuable byproducts such as oil, char, and syngas. Case studies from countries like South Africa and Nigeria demonstrate the potential for scaling up pyrolysis to address waste management issues while generating energy and job opportunities. This review underscores the need for investment, regulatory support, and public awareness to overcome the challenges and unlock the full potential of pyrolysis in Africa. Embracing pyrolysis as a method for managing plastic waste could lead to significant environmental and economic benefits for the continent. Full article

In July 2009, African leaders adopted the Declaration on Land Issues in Africa, reaffirming the commitment of African Union member states to effective land management. The declaration emphasizes the protection of land rights for all, with particular attention to women and marginalized groups. Land governance in Africa, which spans various aspects of society, remains a critical issue and is often a source of conflict and instability across the continent. This study examines the legal and institutional reforms of land governance in Francophone Africa (Benin, Burkina Faso, Ivory Coast, Mali, and Senegal), analyzing their objectives, outcomes, and the challenges associated with their implementation. In addition, this study highlights examples of both effective and ineffective reform implementations based on case studies from countries with notable successes (Ethiopia, Rwanda, Mauritius, Ghana, and Madagascar) and failures (South Africa and Zimbabwe). Finally, this study offers recommendations for improving sustainable land management while considering social, economic, political, and environmental dimensions. The methodology employed is based exclusively on a systematic review guided by the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) approach, applied to the ROSES (Reporting Standards for Systematic Evidence Syntheses) protocol. This approach facilitated the selection of 57 relevant documents retrieved from databases such as Scopus, Web of Science, PubMed, and Google Scholar. Land governance in Francophone Africa varies significantly from country to country and cannot be comprehensively addressed in a study of this scope. Nevertheless, this research study identifies common challenges, opportunities, and measures that could inspire reflection in other countries. In several cases, administrative and customary authorities play central roles in land management. However, their overlapping responsibilities, often marked by corruption, extend procedures and exacerbate local conflicts. Full article

This study examines the potential of grain trade within the context of global commerce, highlighting its role as a primary component of the worldwide agricultural market and a crucial factor in ensuring global food security and price stability. To achieve the research objectives, we utilized panel data from Russia, a leading player in the grain market, and employed a gravity model along with Poisson pseudo-maximum likelihood (PPML) to analyze the impact of demand factors and the economic openness of importing countries, as well as the effects of distance, sea access, borders, language, trade unions, and tariffs on exports. Our research challenges the notion that an increase in the wealth of countries leads to a corresponding rise in trade between them. In the case of grain, evidence indicates a negative contribution of GDP per capita in importing countries. The gravity model and PPML enabled us to assess individual country effects and quantitatively evaluate the potential for increasing Russian grain exports to Asian and African nations. We propose recommendations for enhancing domestic grain production and improving the effectiveness of marketing strategies in countries with underutilized export potential. Full article

Antimicrobial resistance (AMR) poses a critical global health threat, driving the search for alternative treatments to conventional antibiotics. In this study, the antibacterial properties of honeybee venom (BV) and fungal Monascus purpureus red dye (RD) were evaluated against three multidrug-resistant bacterial pathogens. Extracts of BV and RD exhibited dose-dependent antibacterial activity against the three tested bacteria, with their strongest effectiveness against S. aureus (minimum inhibitory concentrations [MIC] = 3.18 and 6.315 μg·mL⁻¹, respectively). Although the three bacterial strains were resistant to the antibiotic ampicillin-sulbactam (10/10 µg), both extracts exhibited superior antibacterial activity against the three bacterial strains compared to five standard antibiotics, especially RD extract, which produced the largest inhibition zone (20 ± 0.20 mm) against S. aureus. The larger inhibition zones against S. aureus suggest its high sensitivity, whereas E. coli and E. faecalis exhibited smaller inhibition zones, indicating less sensitivity to BV and RD extracts. Differences in the inhibition zones suggest the variations in antimicrobial activity between the two extracts and their strain-specific effectiveness. Scanning electron microscopy (SEM) revealed that BV and RD extracts disrupted the bacterial plasma membrane, suggesting that the bioactive compounds penetrate the bacterial cell wall and alter its integrity. Furthermore, GC–MS-based analysis revealed that the chemical composition of BV and RD extracts exhibited highly diverse structures, including complex polycyclic systems, porphyrins, steroids, and esters. For instance, 42 metabolites were identified in the BV extract, which mainly were organic and metal–organic compounds; however, only 23 molecules were identified in RD extract, which mainly were fatty acids and their derivatives. The diversity in the chemical compositions of both extracts highlights their potential applications in pharmaceuticals, materials, and biochemistry fields. Collectively, these findings indicate that honeybee venom and the red dye from M. purpureus have promising antibacterial properties and warrant further investigation as potential alternatives to conventional antibiotics. Further multi-ligand docking-based virtual screening studies are required to identify the most promising detected metabolite(s) within both BV and RD extracts. Full article

In the last two decades, the pig market in Poland has been influenced by two key events: accession to the European Union and the spread of African swine fever (ASF). During this time, the pig population in Poland has almost doubled, and the number of farms keeping pigs has fallen almost tenfold. On the other hand, the import of piglets intended for further rearing has increased significantly, which reduces the value added to production retained in the country. The changes taking place in the pig market in Poland in the conditions of ASF have, therefore, prompted the question of which pig-keeping systems are more profitable for pig producers, and identifying this relationship was the main objective of the analysis in this study. This research was conducted using source data from the databases of the Central Statistical Office, the FADN, and the Integrated Agricultural Market Information System of the Ministry of Agriculture and Rural Development. Factors influencing the value of pig production were identified using panel regression, and profitability analysis was performed based on changes in the levels of and relationship between feed costs and live pig prices. Feed consumption was determined based on feed rations for individual utility groups in both products. As the analysis has shown, a closed cycle of pig farming is characterized by better stability and resistance to market shocks compared to an open cycle (over the entire period under review, only the closed system ensured a positive surplus of production value over feed costs), which significantly increases the possibility of obtaining a positive surplus of production value over the value of the main cost, which is the feed cost. However, with the occurrence of extraordinary situations, such as an ASF outbreak in the herd, rebuilding production in a closed cycle may be much more difficult and expensive than production in an open cycle.

Background/Objectives: The Addis Declaration on Immunization (ADI) is a historic pledge aiming at increasing political will to achieve universal access to immunization services and includes ten commitments to shape the future of immunization in Africa. Methods: To analyze African countries’ performance in achieving the fourth ADI commitment, a cross-sectional retrospective study was conducted including the 54 African Member States of the World Health Organization (WHO) out of 55 African Union (AU) Member States. The fourth ADI commitment aims at increasing the effectiveness and efficiency of immunization delivery systems and has four performance indicators. Results: The median percentage of districts with less than 10% of dropout rate between the first dose of diphtheria–tetanus–pertussis-containing vaccine (DTP1) and the third dose (DTP3) was 86.5%, ranging from 22% to 100%. Thirty-four countries (63%) recorded 80% or above of districts with less than 10% dropout rate between DTP1 and DTP3. Eleven countries (20.3%) and ten countries (18.5%) sustained 90% or above coverage for DTP3 and first dose of measles-containing vaccine (MCV1), respectively, in the past three years (2021–2023). Four countries (7.4%) had 44.5 skilled health workers per 10,000 people. Out of the 54 WHO Member States, 7 achieved at least three of the four indicators of the fourth ADI commitment (13%). Conclusions: It is critical, as a follow up to this study, to document best practices from the seven countries that achieved the fourth ADI commitment. Additionally, a deeper analysis of factors associated with achieving the ADI commitments is required. Full article

Push–pull technology (PPT) integrates maize with the legume fodder Desmodium sp. and the border crop Brachiaria sp., aiming to enhance maize production in Rwanda. Despite its potential, the adoption of complementary soil management practices (SMP), vital for PPT’s success, remains low. This study employs spatial econometric methods to evaluate the determinants of SMP adoption and the interdependencies in decision-making among PPT-practicing farmers. We constructed a spatial weight matrix based on a global Moran’s I index and identified optimal model parameters through principal component analysis. Utilizing a spatial Durbin probit model (SDPM), we assessed the spatial interdependence of SMP adoption decisions among maize farmers. Our findings reveal significant spatial dependence in SMP adoption within a 1.962 km radius, with improved seed usage, household income, yield, farmer group membership and size of land cultivated being key factors positively influencing adoption. We propose a “nonequilibrium promotion strategy” to enhance SMP adoption, emphasizing the establishment of pilot regions to broaden outreach. Additionally, fostering technical training and selecting farmers with adequate resources as demonstration leaders can enhance spatial spillover effects. This research provides insights for developing policies to scale up push–pull technology in Rwanda and across Sub-Saharan Africa. Full article

This study examines the role of humanitarian diplomacy during the Tigray humanitarian crisis in Ethiopia, a humanitarian disaster marked by severe shortages in food, healthcare, and essential services that deeply affect civilians. A qualitative approach using both primary and secondary data grounds the study by exploring key actors in humanitarian diplomacy, their successes, and barriers to aid delivery. Humanitarian actors, such as UN agencies, international NGOs, donor countries, the EU, the US, and the African Union, have engaged with the Ethiopian government, the TPLF, and the Tigray Transitional Government to alleviate the crisis. Notable achievements in humanitarian diplomacy include negotiations, information gathering, communication, civilian needs assessment, resource mobilization, advocacy for international law, and distressed civilians. Humanitarian diplomacy has facilitated international aid operations, saving lives during critical periods, despite practical difficulties. Diplomatic efforts have faced significant interruptions due to access restrictions imposed by the Ethiopian government, security threats from ongoing fighting leading to attacks on aid convoys and casualties among aid workers, and bureaucratic obstacles imposed by the Ethiopian government. This study highlights the necessity for effective humanitarian diplomacy in accounting for complex political landscapes in conflict-affected regions, developing flexible strategies that enhance access to aid, and improving humanitarian interventions.

Africa’s health landscape is rapidly changing, requiring new solutions such as a focus on health literacy. However, there is currently a limited overview of the development and application of health literacy in African countries and societies. This scoping review aims to analyze scientific publications on health literacy in Africa with regards to research approaches, historical developments, geographic origins, target populations and settings, and topical interests. The research followed Arksey and O’Malley six steps of scoping reviews and employed the Joanna Briggs Institute’s PCC method for search string formulation and the PRISMA-SCR checklist for reporting. On 11 July 2022, the following six databases were searched for scientific articles including included reports, policy briefs, book chapters, and research publications: PubMed, PsycINFO, Cochrane Library, ERIC, African Journals Online, and African Index Medicus. A total of 336 articles were identified. The research team co-developed a codebook and three researchers independently extracted data. The analysis provided the most comprehensive overview of the current scope and scale of health literacy in Africa to date. The publications represented 37 of the 54 African Union countries and dated back to 2001, although most were published in the last decade. The content analysis identified 13 broad themes, including mental health, communicable diseases, non-communicable diseases, maternal health, digital health, information and communication, health care, prevention and health promotion, conceptual perspectives, cultural perspectives, and outcomes and measurement. The analysis of target groups revealed a wide range of actors involved in different settings, mostly in health care or community settings. These comprehensive and novel findings can be used to prioritize future actions for public and professional capacity building, policy development, and improved practice to improve health literacy for all in Africa.

Peste des Petits Ruminants (PPR) disease is widely distributed in Africa. Live attenuated PPR vaccines are produced using approved Nigeria 75/1 and Sungri/96 strains by the World Organisation of Animal Health (WOAH) to control the disease. These PPR vaccines are very efficacious; however, the main challenge is the maintaining of the cold chain during vaccine distribution and delivery. This study evaluated the thermotolerance of freeze-dried and reconstituted PPR Nigeria 75/1 vaccines from vaccine manufacturers using eight stabilizer formulations (lactalbumin hydrolysate and sucrose, sucrose and peptone, Weybridge medium, trehalose, Lactose and N-Z Amine, lactalbumin hydrolysate, sucrose and L glutamine, skimmed milk, and lactalbumin hydrolysate, maltose and gelatine). Aliquots of the reconstituted PPR vaccine batches were titrated after 2, 4, and 6 h of storage at 4 °C and 40 °C. The PPR vaccines were also titrated after storage at 40 °C and 45 °C for 3 and 5 days. The results showed that reconstituted PPR vaccine stabilized with lactalbumin hydrolysate–sucrose promoted tolerance at 40 °C for 6 h. It was also noted that all reconstituted PPR vaccine formulations except the formulation stabilized with lactalbumin hydrolysate–maltose–gelatine maintained the titre above a 10^2.5 TCID₅₀/dose after 4 h of storage at 4 °C. Furthermore, the results showed that the PPR vaccine formulation containing lactalbumin hydrolysate sucrose was as the only one that maintained the titres above 10^2.5 TCID₅₀/dose after storage at 45 °C for 5 days, with a titre loss of 10^0.95 TCID₅₀/dose. Therefore, vaccine manufacturers producing PPR vaccines for use in tropical field regions could preferably use lactalbumin hydrolysate–sucrose stabilizer in vaccine formulation. Full article
