A recent study by Umeh et al. (2025) titled “A review of the sidelined pollutant: Reviving the fight against heavy metal contamination in an era of emerging contaminants” published in Toxicology Reports reveals that despite the growing research focus on emerging pollutants such as microplastics (MPs) and per- and polyfluoroalkyl substances (PFAS), heavy metals—due to their persistence, toxicity, and widespread presence—continue to pose a substantial and underappreciated threat to public health and environmental sustainability.

“

Heavy metal contamination in groundwater remains a critical, underrecognized threat, demanding renewed global attention, updated technologies, and urgent policy action.
– Umeh et al. 2025

This review paper delivers a compelling and urgent call to action, drawing attention to the critically overlooked issue of heavy metal (HM) contamination in groundwater. Despite the growing research focus on emerging pollutants such as microplastics (MPs) and per- and polyfluoroalkyl substances (PFAS), heavy metals—due to their persistence, toxicity, and widespread presence—continue to pose a substantial and underappreciated threat to public health and environmental sustainability.

The review aims to (1) reignite global awareness of HM pollution in groundwater systems, (2) highlight research gaps and the underexplored risks of heavy metals in contrast to newer contaminants, and (3) provide a comprehensive analysis of current knowledge surrounding HM sources, pathways, detection, toxicity, and remediation efforts.Currently, over two billion people globally depend on groundwater for their daily needs—yet many water delivery systems still rely on outdated infrastructure that leaches lead and other hazardous metals. This review is more than a scientific summary; it’s a critical reminder that heavy metals remain a profound and ongoing environmental hazard. The authors urge policymakers, researchers, and engineers to prioritize heavy metal pollution with the same urgency as emerging contaminants—adopting smarter, more sustainable strategies for monitoring, remediation, and long-term protection of groundwater resources.

How the Study was Conducted

This study employed a structured literature review methodology, prioritizing a systematic analysis of existing research over experimental or field-based investigations. A total of 227 peer-reviewed papers were carefully selected and examined, primarily sourced from established scientific databases such as Elsevier, Nature, Springer, and Web of Science. To ensure a thorough and focused review, the authors developed a targeted search strategy using a combination of specific keywords, including “groundwater”, “heavy metals”, “sources”, “models”, “transport”, “fate”, “toxicity”, “global trends”, “sustainability”, and “treatment”. These terms were combined in various ways to capture a wide breadth of relevant literature on the subject. The scope of the review was deliberately confined to heavy metal contamination in groundwater systems. Broader environmental matrices such as soil, air, and surface water were excluded from the analysis, though the authors acknowledged that integrating these additional perspectives would be beneficial for a more holistic understanding of heavy metal pollution. One limitation noted was the reliance solely on a select group of databases; other sources and search engines were not utilized, leaving room for potential insights that might exist outside of the reviewed platforms.

What the Authors Found

Despite declining research attention, heavy metal (HM) contamination in groundwater remains a widespread, unresolved, and dangerous public health threat, with global hotspots, significant health risks, and major gaps in treatment technologies, monitoring standards, and pollutant interaction studies—highlighting the urgent need for renewed global focus and coordinated action.

Why is this important

1. Heavy Metals in Groundwater Threaten Human Health
Over 2 billion people rely on groundwater, often exposed to toxic levels of lead, arsenic, cadmium, and mercury—linked to cancer, organ damage, and developmental issues, particularly in children.

2. Environmental Harm Is Deep and Long-Lasting
Heavy metals persist in ecosystems for centuries, disrupting soil chemistry and harming plant and animal life. Once they enter aquifers, removal is extremely difficult.

3. Research Is Declining at the Wrong Time
Since 2022, studies on heavy metal contamination have dropped, as global focus shifts to newer pollutants like microplastics and PFAS—creating a dangerous illusion that the HM problem is solved.

4. Technology and Monitoring Are Lagging
Current detection and sampling methods are outdated and inconsistent. Advanced tools such as biosensors and nanotechnology exist but remain underused in real-world monitoring.

5. Public Awareness and Policy Are Failing
Without reliable data and innovation, policies remain weak. Public misconceptions lead to underfunding and inaction—leaving communities vulnerable to an ongoing, underestimated threat.

What the Authors Recommended
- The authors advocate standardising protocols globally and adopting advanced technologies like biosensors, nanotech, and smart sensors to improve accuracy, speed, and field-based testing of heavy metals in groundwater.
- The authors urge reinvestment in long-term studies on heavy metals, especially their interactions with pollutants like PFAS and microplastics, and examination of their behavior in diverse geological and climatic settings.
- Update water safety regulations to address mixed contaminant risks, phase out hazardous legacy infrastructure like lead pipes, and foster stronger collaboration between scientists, policymakers, and utilities.
- Furthermore, correct the misconception that HM threats are over by launching education campaigns, supporting community-based water monitoring, and improving communication about health risks and solutions.
- In addition, support the development of cost-effective, eco-friendly tools, automated microfluidic systems, and integrated platforms that can detect multiple contaminants (HMs, MPs, PFAS) in real time.
In conclusion, the study by Umeh et al. (2025) serves as a critical wake-up call to scientists, policymakers, and the global community: heavy metal contamination in groundwater remains a persistent and dangerous threat that cannot be sidelined. As the world turns its attention to emerging pollutants, it is vital not to abandon the fight against heavy metals, whose long-lasting health and environmental consequences continue to endanger billions.

A recent study by Onawo, O. L., & Egboduku, W. O. (2025) titled “Highlighting the untapped potential of neglected and underutilized crop species for sustainable food security published in Journal of Underutilized Legumes, reveals that neglected and underutilized crop species (NUCS) have immense untapped potential to enhance sustainable food systems

“

NUCS offer immense potential for sustainable food security through improved nutrition, climate resilience, and biodiversity, yet remain largely underutilized.
– Onawo, O. L., and Egboduku, W. O. (2025

This study sheds light on a critical yet often overlooked aspect of global agriculture and nutrition—the role of Neglected and Underutilized Crop Species (NUCS). These crops, which have traditionally been cultivated and consumed in various regions, have largely been pushed aside in favor of widely commercialized staples such as wheat, rice, and maize. The study argues that NUCS hold immense potential for advancing sustainable food security, particularly in regions facing the dual threats of climate change and economic instability. Unlike many mainstream crops, NUCS are typically well adapted to local environmental conditions, require fewer agricultural inputs, and can thrive in marginal soils, making them more environmentally sustainable. Beyond their agronomic resilience, NUCS are also vital from both cultural and nutritional standpoints. Rich in essential nutrients and often integral to local food traditions, these crops offer diverse dietary benefits. However, they remain significantly underfunded, under-researched, and undervalued in mainstream agricultural systems and policy frameworks. Importantly, the study calls for increased investment in research, development, and policy support for NUCS to unlock their full potential. Doing so would not only enhance agricultural biodiversity but also contribute to more resilient and locally driven food systems.

How the Study was Conducted

The study employed a desk review methodology; through an extensive literature review, the authors examined previously published studies and databases related to neglected and underutilized crop species (NUCS), with a focus on their production, nutritional value, and economic potential. A comparative analysis was conducted between NUCS and widely cultivated staple crops to assess the potential of NUCS in contributing to sustainable agriculture and resilient food systems. The study had a global scope, incorporating data from diverse regions where NUCS are traditionally grown—particularly in parts of Africa, Asia, and South America.

What the Authors Found

The authors found that neglected and underutilized crop species (NUCS) have immense untapped potential to enhance sustainable food systems—offering superior nutrition, climate resilience, and cultural value—but they remain overlooked due to research, policy, and funding gaps.

Why is this important

Food Security at Risk: With climate change, soil degradation, and growing populations, relying only on major staple crops is becoming increasingly risky. NUCS (Neglected and Underutilized Crop Species) offer an alternative that’s better suited to diverse local conditions.

Boosting Nutrition: Many of these underused crops are rich in vitamins, minerals, and fiber. Reviving them can directly tackle malnutrition and hidden hunger.

Climate Adaptation: NUCS are often hardy crops that thrive in drought-prone or low-input areas. Promoting them can support farming communities that struggle with increasingly unpredictable weather patterns.

Preserving Biodiversity: Focusing on just a few global crops has eroded agrobiodiversity. Cultivating a wider range of species helps protect ecosystems and genetic resources.

Empowering Local Economies & Cultures: These crops are part of traditional diets and farming practices. Supporting them can strengthen cultural identity, empower smallholder farmers, and open new markets.

What the Authors Recommended
- The authors advocate promoting the nutritional, environmental, and cultural benefits of NUCS through public campaigns, community outreach, and school programs to drive demand and adoption.
- The study also emphasizes the push for dedicated government policies and increased funding for research, conservation, and the integration of NUCS into national and regional agricultural strategies.
- Provide farmers with training, resources, and incentives to cultivate NUCS profitably, while improving access to quality seeds and local markets.
- Incorporate NUCS into food aid programs, institutional procurement (like school meals), and climate-resilient farming practices to boost food security.
- Invest in scientific research to enhance breeding, agronomic practices, and post-harvest processing—ensuring NUCS are viable, productive, and competitive.
In conclusion, the study by Onawo and Egboduku (2025) underscores the urgent need to re-evaluate and reintegrate neglected and underutilized crop species (NUCS) into mainstream agriculture. As the world grapples with mounting food insecurity, climate challenges, and nutritional deficiencies, NUCS present a viable, sustainable, and culturally rich solution. Unlocking their full potential will require coordinated efforts across research, policy, and grassroots implementation. By investing in these overlooked crops, we can build more resilient food systems, empower local communities, and pave the way for a healthier, more food-secure future.

Ownership and Usage Policy

A recent study by Kokori et al. (2025) titled “Optimising pre-eclampsia prevention: Embracing low-dose calcium in sub-Saharan Africa” published in International Journal of Gynecology & Obstetrics reveals that low-dose calcium supplementation (500 mg/day) could be a game-changing intervention for preventing pre-eclampsia in sub-Saharan Africa.

“

Low-dose calcium supplementation (500 mg/day) is a practical, effective strategy to prevent pre-eclampsia in sub-Saharan African pregnancies.
– Kokori et al. 2025

A new study tackles a critical maternal health issue in sub-Saharan Africa: pre-eclampsia—a dangerous pregnancy complication linked to high blood pressure and organ damage. The authors advocate for a shift from the widely recommended high-dose calcium supplementation (1500–2000 mg/day) to a more practical, affordable low-dose alternative (500 mg/day) as a preventive measure.
This proposed change could have a major impact in low-resource settings, where the cost, availability, and side effects of high-dose regimens often limit their effectiveness. The study highlights how low-dose calcium supplementation offers a safe, effective, and more feasible solution to reduce pre-eclampsia risk, especially in areas where access to prenatal care is limited. Evidence from Ghana, Nigeria, and Ethiopia shows a clear association between low maternal calcium levels and higher rates of pre-eclampsia. Compared to high-dose supplementation, the low-dose approach may offer similar protective benefits while enhancing compliance and lowering barriers to access.

How the Study was Conducted

The study employed a narrative review methodology, the study systematically gathered and critically analyzed existing research related to calcium supplementation and the prevention of pre-eclampsia in sub-Saharan Africa. To conduct this review, the authors searched multiple academic databases, including PubMed, Google Scholar, Cochrane Library, and Scopus. The search was limited to peer-reviewed articles published in English between 2000 and March 2024. Key search terms included: “pre-eclampsia,” “low-dose calcium,” “maternal health,” “sub-Saharan Africa,” and “nutritional interventions.”

A wide range of literature was included based on specific inclusion criteria, encompassing:
- Clinical trials
- Observational studies
- Systematic reviews
- Reference lists from relevant papers
The overarching aim of this approach was to evaluate the feasibility and effectiveness of low-dose calcium supplementation (500 mg/day) as an alternative to the high-dose standard. In doing so, the authors sought to compare outcomes between low- and high-dose calcium regimens and identify context-specific barriers and enablers to implementation, generate evidence-based insights to support policy and clinical decision-making that align with the region’s socioeconomic and healthcare challenges

What the Authors Found

The authors found compelling evidence that low-dose calcium supplementation (500 mg/day) could be a game-changing intervention for preventing pre-eclampsia in sub-Saharan Africa, with several key findings drawn from both global trials and regional data.

Why is this important

Maternal and Neonatal Survival: Pre-eclampsia is one of the leading causes of maternal and neonatal deaths in the region. It’s especially devastating in areas where access to quality healthcare is limited. Preventing it through something as simple and affordable as low-dose calcium could save countless lives.

Practicality in Resource-Limited Settings: High-dose calcium has always been recommended—but it’s expensive, difficult to distribute, and often poorly tolerated. Low-dose calcium, in contrast, is cheaper, easier to take, and more widely acceptable, especially in regions where pregnant women may struggle with multiple health challenges and limited prenatal care.

Scalability: If low-dose calcium proves as effective as high-dose (as some studies suggest), it means health ministries and aid organizations can scale up prevention programs faster, reaching more women without needing massive resources.

Empowering Communities: The study also emphasizes the importance of awareness and education. By equipping healthcare workers and communities with the knowledge and tools to prevent pre-eclampsia, it promotes self-reliance and informed health choices.

Advancing Equity: Ultimately, this is about closing the maternal health gap between rich and poor nations. It’s a move toward ensuring that where a woman lives doesn’t determine whether she survives pregnancy.

What the Authors Recommended
- The authors urge health systems across sub-Saharan Africa to incorporate 500 mg/day calcium supplementation into routine antenatal care, particularly in regions with low dietary calcium intake. This shift would make supplementation a proactive, standardized part of maternal health services.
- Effective implementation hinges on awareness and understanding. The authors recommend training healthcare workers to communicate the benefits and safety of calcium supplementation using culturally appropriate messaging and running public awareness campaigns to demystify pre-eclampsia and reduce stigma or misinformation.
- To enhance uptake, the authors call for practical innovations and supply chain improvements to develop cost-effective, user-friendly formulations like chewable or flavored tablets as well as to ensure consistent availability of low-dose calcium in clinics, especially in rural and underserved areas.
- The study emphasizes the need for strong policy backing and financial support, including listing low-dose calcium on national essential medicines lists, incorporating it into maternal health policies and guidelines and subsidizing or offering free distribution through public health programs.
- Recognizing Africa’s diverse cultural and healthcare contexts, the authors recommend tailoring interventions to local realities rather than adopting a one-size-fits-all approach. They also advocate for more local research on the effectiveness, safety, and adherence to low-dose calcium and exploring combination strategies with vitamin D or low-dose aspirin, especially for high-risk pregnancies.
In conclusion, the study by Kokori et al. (2025) presents a compelling case for rethinking pre-eclampsia prevention strategies in sub-Saharan Africa by embracing low-dose calcium supplementation. With its affordability, ease of implementation, and strong potential to save maternal and neonatal lives, this approach offers a transformative solution tailored to the region’s healthcare realities. By aligning policy, education, and supply chains to support this shift, stakeholders can make significant strides toward equitable, sustainable maternal health outcomes across the continent.

A recent study by Foláyan et al. (2025) titled “Strengthening health systems to tackle oral diseases in Africa: Africa Centres for Disease Control and Prevention’s role” published in Frontiers in Public Health reveals that there is an acute shortage and uneven distribution of oral health professionals across the continent, with rural and low-income populations disproportionately underserved.

“

Africa faces a severe shortage and unequal distribution of oral health professionals, leaving vulnerable populations underserved. – Foláyan et al. 2025

This study focuses on the growing public health challenge of oral diseases in Africa and highlights the pivotal role the Africa Centres for Disease Control and Prevention (Africa CDC) can play in addressing it. Despite the high prevalence of oral conditions—like untreated caries, periodontal disease, oral cancers, and HIV-related lesions—oral health remains largely overlooked in national health strategies across the continent. Through a rapid review of 18 studies, the authors identified severe shortages and maldistribution of the oral health workforce, especially in rural areas. Many countries face significant gaps in dental education, infrastructure, and services. Vulnerable populations—such as women, children, people in poverty, and those in remote areas—are disproportionately affected due to systemic inequities in access and care. The paper calls for strategic integration of oral health into broader health systems and policies. Promising solutions include mobile dental units, expanded roles for mid-level providers like dental therapists, and strengthened education and retention incentives for oral health workers.

How the Study was Conducted

This study employed a rapid review methodology to assess the current state of oral health systems and workforce challenges across Africa. The researchers conducted a comprehensive literature search across multiple databases—EBSCO, PubMed, ProQuest, and ScienceDirect—using targeted keywords and Medical Subject Headings (MeSH) such as “oral health workforce”, “dental professional shortages”, “recruitment”, “retention”, and “Africa”. Out of 2,014 initially identified articles, duplicates were removed, and 1,069 studies were screened. Following a rigorous selection process, 18 studies were ultimately included based on their direct relevance to the size and distribution of the oral health workforce, retention strategies, access to care, and systemic outcomes.
The inclusion criteria covered a range of study designs, including cohort studies, cross-sectional studies, and qualitative research, all focusing on oral health professionals such as dentists, hygienists, and dental therapists. Detailed data were extracted on authorship, publication year, geographic focus, study objectives, key findings, and recommendations. By synthesizing this body of evidence, the review mapped out critical systemic gaps and highlighted strategic interventions with the potential to transform oral health care delivery across the African continent.

What the Authors Found

The authors found that there is an acute shortage and uneven distribution of oral health professionals across the continent, with rural and low-income populations disproportionately underserved. For example, in Nigeria, only 20% of dentists serve rural areas, despite the majority of the population residing there. Contributing factors include limited dental training institutions, inadequate policy frameworks, and the confinement of services to emergency care. Vulnerable groups—such as children, women, and rural dwellers—face compounded barriers due to structural inequities and cultural constraints.

Innovative interventions, including mobile dental clinics and the deployment of mid-level providers like dental therapists and hygienists, have shown promise in improving access and building local capacity. Programs such as Rwanda’s Human Resources for Health initiative demonstrate how international collaboration and localized training can address workforce deficits. The study emphasizes the need for stronger policies, better infrastructure, and the integration of oral health into broader universal health coverage (UHC) strategies to create sustainable change.

Why is this important

This study matters because it shines a spotlight on an often neglected crisis. Oral diseases affect nearly half a billion people in the WHO African Region, and they don’t just cause pain or tooth loss—they’re linked to systemic health conditions like heart disease, diabetes, and even complications in pregnancy. Yet, oral health remains sidelined in most national health plans.

The findings underscore how poor access, workforce shortages, and fragmented systems leave vulnerable communities—children, women, and rural families—without basic care. This isn’t just a health issue; it’s a social justice issue.

What’s powerful here is the potential for transformation. By involving the Africa CDC, the study calls for bold, system-wide integration of oral health into broader public health frameworks, including universal health coverage. It’s a chance to build resilient, community-orientated solutions that prevent disease before it starts—like mobile clinics, task-shifting, and inclusive policies.

What the Authors Recommended
- Governments should embed oral health within broader health strategies—especially universal health coverage (UHC) and non-communicable disease (NCD) frameworks—to secure dedicated funding, align policies, and strengthen infrastructure.
- Expand and improve dental education, especially for mid-level providers like therapists and hygienists. Prioritize workforce retention, rural deployment, and incentives to address shortages and urban-rural disparities.
- Invest in cost-effective models such as mobile clinics and school-based programs to improve access in underserved areas. These platforms can also provide local employment and hands-on training.
- Utilize the Africa CDC’s leadership to coordinate data-driven policies, technical support, cross-border initiatives, and promote local production of essential oral health products in line with its “New Public Health Order.”
- Develop targeted strategies for vulnerable groups—especially children, women, and rural communities—and implement robust systems for monitoring, evaluation, and stakeholder engagement across all levels of care.
In conclusion, the study by Foláyan et al. (2025) brings urgent attention to the widespread neglect of oral health across Africa and outlines a clear roadmap for change. By integrating oral health into broader health systems, investing in workforce development, and leveraging the Africa CDC’s leadership, there is a powerful opportunity to close the care gap and promote equitable access for all—especially the most vulnerable. Strengthening oral health is not just a medical imperative; it’s a step toward justice, resilience, and a healthier future for the continent.

A recent study by Okumu et al. (2025) titled “Elevating larval source management as a key strategy for controlling malaria and other vector-borne diseases in Africa” published in Parasites & Vectors by Springer Nature, reveals that larval source management (LSM) is a powerful yet underutilized tool for malaria control, particularly in Africa.

“

Larval source management significantly reduces mosquito populations and enhances malaria control but remains underfunded and underutilized in Africa.
-Okumu et al. 2025

This study advocates for the elevation of larval source management (LSM) as a critical, yet underutilized, strategy for controlling malaria and other vector-borne diseases in Africa. Although LSM has historically demonstrated success, particularly in countries that have eliminated local malaria transmission, its broader implementation remains limited—primarily due to funding constraints and operational challenges. The World Health Organization (WHO) recommends LSM as a complementary approach alongside insecticide-treated nets (ITNs) and indoor residual spraying (IRS). However, its adoption is often hindered by the transient nature of mosquito breeding sites, difficulties in locating larval habitats, and a lack of high-quality epidemiological evidence. As progress in malaria elimination stagnates, there is growing urgency to reconsider and diversify vector control strategies beyond insecticide-based interventions targeting adult mosquitoes indoors.

This paper underscores the long-term effectiveness of LSM through expert discussions, narrative analyses of malaria-free countries, and mathematical modeling. Key findings reveal that LSM—through the application of larvicides and environmental sanitation—can significantly suppress mosquito populations. Models further demonstrate that integrating LSM with existing interventions can mitigate challenges like insecticide resistance and outdoor biting. Despite its potential, LSM receives limited large-scale funding and lacks the trained workforce needed for widespread implementation. Current funding structures tend to favor ITNs and IRS due to their ability to deliver short-term, easily measurable results, often sidelining LSM in national malaria control programs.

How the Study was Conducted

The study was conducted through a global, cross-disciplinary collaboration that employed a combination of expert discussions, narrative review, and mathematical modeling to evaluate the effectiveness of larval source management (LSM) in malaria control. Researchers and professionals from various fields engaged in detailed online discussions, sharing practical insights and challenges related to implementing LSM. In parallel, a narrative review was conducted, focusing on countries that have successfully eliminated local malaria transmission. This review analyzed historical mosquito control strategies and highlighted the specific role of LSM in those successes. To complement these qualitative insights, the study also utilized two different malaria transmission models to assess the potential impact of integrating LSM with existing vector control methods. The modeling estimated LSM’s effectiveness in reducing malaria incidence, managing insecticide resistance, and addressing the growing challenge of outdoor mosquito biting.

What the Authors Found

The authors found that larval source management (LSM) is a powerful yet underutilized tool for malaria control, particularly in Africa. Their findings highlight that LSM can significantly reduce mosquito populations, delivering widespread community benefits. However, despite its proven effectiveness, LSM remains limited in implementation due to several key barriers: insufficient large-scale funding, a lack of trained personnel, and restrictive World Health Organization (WHO) guidelines that call for high-quality epidemiological evidence—something difficult to obtain due to challenges in locating mosquito larval habitats. The study also noted that countries that have successfully eliminated malaria often relied on LSM, underscoring its potential impact. Mathematical modeling further supports LSM’s value, suggesting that when combined with existing vector control measures, it can enhance malaria prevention by reducing insecticide resistance and targeting outdoor-biting mosquitoes. Nonetheless, the global focus on commodity-based interventions like insecticide-treated nets (ITNs) and indoor residual spraying (IRS)—which are easier to quantify and monitor—has constrained the broader adoption of LSM.

Why is this important

This study is important because it advocates for a shift in malaria control strategies, emphasizing the underutilized potential of larval source management (LSM) in Africa. While insecticide-treated nets (ITNs) and indoor residual spraying (IRS) have been the dominant approaches, malaria elimination progress has stalled, requiring alternative solutions to address emerging challenges like insecticide resistance and outdoor mosquito biting.

What the Authors Recommended
- LSM requires dedicated funding, but current global malaria budgets prioritize insecticide-treated nets (ITNs) and indoor residual spraying (IRS). The authors urge reallocation of resources to expand LSM initiatives.
- Countries need trained personnel to implement LSM effectively. This includes entomologists, field workers, and operational managers for sustained mosquito population control.
- The World Health Organization (WHO) limits LSM adoption due to a lack of large-scale clinical trials. The authors recommend recognizing alternative forms of evidence such as historical successes and mathematical modeling.
- LSM works best when adjusted to specific environments. The authors propose context-sensitive approaches, including urban larviciding, environmental sanitation, and habitat modification.
- A multifaceted strategy combining LSM, ITNs, and IRS can improve malaria prevention by reducing insecticide resistance and outdoor biting mosquitoes.
- New tools such as low-cost mapping systems, mobile data collection, and aerial spraying can enhance mosquito habitat identification and LSM effectiveness.
In addition, malaria control frameworks should embrace LSM as a core intervention rather than treating it as a supplementary measure. Countries must actively push for policy updates and funding adjustments.

In conclusion, this study highlights larval source management (LSM) as a vital yet underutilized tool in the fight against malaria and other vector-borne diseases in Africa. By overcoming funding limitations, training gaps, and operational challenges, and by integrating LSM with existing interventions like insecticide-treated nets and indoor residual spraying, malaria control programs can significantly enhance their effectiveness. Embracing LSM as a core component of comprehensive vector management offers a promising pathway to overcoming insecticide resistance and outdoor mosquito biting, ultimately accelerating progress toward malaria elimination across the continent.
