Remembering Joseph Ngugi

From Murang’a to the world: remembering Joseph Ngugi, champion of peer learning for community health

Reda SadkiGlobal health, Leadership

“What keeps me going now is the excitement of the clients who receive the service and the sad faces of those clients who need the services and cannot get them.” Joseph Mbari Ngugi shared these words on May 30, 2023, capturing the profound empathy and dedication that defined his life’s work. This commitment to serving those most in need—and his deep awareness of those still unreached—characterized not only his career as a senior community health officer and public health specialist in Kenya’s Murang’a County, but also his extraordinary five-year journey through the Geneva Learning Foundation’s most rigorous learning programmes. It was the morning of the first day of August, 2025. The message from his daughter was simple and devastating: “Hello this is Wanjiru Mbari Ngugi’s Daughter. I am the one currently with his phone. This is to inform you that Dad passed away this morning.” Joseph’s passing represents more than …

WHO Global Conference on Climate and Health: New pathways to overcome structural barriers blocking effective climate and health action

Reda SadkiGlobal health

After the World Health Assembly’s adoption of ambitious global plan of action for climate and health, global and country stakeholders are meeting in Brasilia for the Global Conference on Climate and Health, ahead of COP30. Three critical observations emerged that illuminate why conventional global health approaches may be structurally inadequate for the challenges resulting from climate change impacts on health. These observations carry particular significance for global health leaders who now possess a WHA-approved strategy and action plan, but lack proven mechanisms for rapid, community-led implementation in the face of an unprecedented set of challenges. They also matter for major funders whose substantial investments in policy and research have yet to be matched by commensurate support for the communities and health workers who will be the ones to translate better science and policy into action. Signal 1: When funding disappears and demand explodes Seventy percent of global health funding vanished, …

Nigeria Immunization Agenda 2030 Collaborative: Piloting a national peer learning programme

Reda SadkiGlobal health

Insights report about Nigeria’s Immunization Agenda 2030 Collaborative surfaces surprising solutions for both demand- and supply-side immunization challenges When 4,434 practitioners from all 36 states asked why children in their communities remained unvaccinated, the problems they thought they understood often had entirely different root causes. “I ended up being surprised at the answer I got,” said one health worker. Half of the health workers who participated in Nigeria’s largest-ever peer learning exercise in July 2024 discovered that their initial assumptions about local immunization challenges were wrong. The six-week programme generated 409 detailed analyses of local immunization challenges, with each reviewed by peers across the country. One year after The Geneva Learning Foundation launched the first Immunization Agenda 2030 Collaborative, in partnership with UNICEF and Gavi, under the auspices of the Nigeria Primary Health Care Development Agency (NPHCDA), a comprehensive insights report documents findings that illuminate persistent gaps between health system …

Why peer learning is critical to survive the Age of Artificial Intelligence

Why peer learning is critical to survive the Age of Artificial Intelligence

Reda SadkiArtificial intelligence, Global health

María, a pediatrician in Argentina, works with an AI diagnostic system that can identify rare diseases, suggest treatment protocols, and draft reports in perfect medical Spanish. But something crucial is missing. The AI provides brilliant medical insights, yet María struggles to translate them into action in her community. What is needed to realize the promise of the Age of Artificial Intelligence? Then she discovers the missing piece. Through a peer learning network—where health workers develop projects addressing real challenges, review each other’s work, and engage in facilitated dialogue—she connects with other health professionals across Latin America who are learning to work with AI as a collaborative partner. Together, they discover that AI becomes far more useful when combined with their understanding of local contexts, cultural practices, and community dynamics. This speculative scenario, based on current AI developments and existing peer learning successes, illuminates a crucial insight as we ascend into …

What does AI reasoning revolution mean for global health

What does AI reasoning mean for global health?

Reda SadkiArtificial intelligence, Global health

When epidemiologists investigate a disease outbreak, they do not just match symptoms to known pathogens. They work through complex chains of evidence, test hypotheses, reconsider assumptions when data does not fit, and sometimes completely change their approach based on new information. This deeply human process of systematic reasoning is what artificial intelligence systems are now learning to do. This capability represents a fundamental shift from AI that recognizes patterns to AI that can work through complex problems the way a skilled professional would. For those working in global health and education, understanding this transformation is essential. The difference between answering and reasoning To understand this revolution, consider how most AI works today versus how reasoning AI operates. Traditional AI excels at pattern recognition. Show it a chest X-ray, and it can identify pneumonia by matching patterns it learned from millions of examples. Ask it about disease symptoms, and it retrieves …

The funding crisis solution hiding in plain sight

The funding crisis solution hiding in plain sight

“I did not realize how much I could do with what we already have.” A Nigerian health worker’s revelation captures what may be the most significant breakthrough in global health implementation during the current funding crisis. While organizations worldwide slash programs and lay off staff, a small Swiss non-profit, The Geneva Learning Foundation (TGLF), is demonstrating how to achieve seven times greater likelihood of improved health outcomes while cutting costs by 90 percent. The secret lies not in new technology or additional resources, but in something deceptively simple: health workers learning from and supporting each other. Nigeria: Two weeks to connect thousands, four weeks to change, and six weeks to outcomes On June 26, 2025, representatives from 153 global health and humanitarian organizations gathered for a closed-door briefing seeking proven solutions to implementation challenges they knew all too well. TGLF presented evidence from the Nigeria Immunization Agenda 2030 Collaborative that sounds almost …

When funding shrinks, impact must grow: the economic case for peer learning networks

Reda SadkiGlobal health, The Geneva Learning Foundation

Humanitarian, global health, and development organizations confront an unprecedented crisis. Donor funding is in a downward spiral, while needs intensify across every sector. Organizations face stark choices: reduce programs, cut staff, or fundamentally transform how they deliver results. Traditional capacity building models have become economically unsustainable. Technical assistance, expert-led workshops, international travel, and venue-based training are examples of high-cost, low-volume activities that organizations may no longer be able to afford. Yet the need for learning, coordination, and adaptive capacity has never been greater. The opportunity cost of inaction Organizations that fail to adapt face systematic disadvantage. Traditional approaches cannot survive current funding constraints while maintaining effectiveness. Meanwhile, global challenges intensify: climate change drives new disease patterns; conflict disrupts health systems; demographic transitions strain capacity. These complex, interconnected challenges require adaptive systems that respond at the speed and scale of emerging threats. Organizations continuing expensive, ineffective approaches will face programmatic obsolescence. …

More with less

Global health: learning to do more with less

Reda SadkiGlobal health

In a climate of funding uncertainty, what if the most cost-effective investments in global health weren’t about supplies or infrastructure, but human networks that turn learning into action? In this short review article, we explore how peer learning networks that connect human beings to learn from and support each other can transform health outcomes with minimal resources. The common thread uniting the different themes below reveals a powerful principle for our resource-constrained era: structured peer learning networks consistently deliver outsized impact relative to their cost. Whether connecting health workers battling vaccine hesitancy in rural communities, maintaining essential immunization services during a global pandemic, supporting practitioners helping traumatized Ukrainian children, integrating AI tools ethically, or amplifying women’s voices from the frontlines – each case demonstrates how connecting practitioners across geographical and hierarchical boundaries transforms individual knowledge into collective action. When health systems face funding shortfalls, these examples suggest that investing in …

Equity matters: A practical approach to identify and eliminate biases

Patterns of prejudice: Connecting the dots helps health workers combat bias worldwide

Reda SadkiGlobal health

English | Français “I noticed that every time he went to appointments or emergency services, he was often met with suspicion or treated as if he was exaggerating his symptoms,” shared a community support worker from Canada, describing how an Indigenous teenager waited three months for mental health services while non-Indigenous youth were seen within weeks. This testimony was just one of hundreds shared during an unusual global gathering where frontline health workers confronted an uncomfortable truth: healthcare systems worldwide are riddled with biases that determine who lives and who dies. “Equity Matters: A Practical Approach to Identify and Eliminate Biases,” a special event hosted by the Geneva Learning Foundation (TGLF) on 10-11 April 2025, drew nearly 5,000 health professionals from 72 countries. What made the event distinctive wasn’t just its scope, but its approach: creating a forum where community health workers from rural Nigeria could share insights alongside WHO …

L’équité, ça compte: Une approche pratique pour identifier et éliminer les biais

L’équité compte: quand les soignants du monde entier témoignent des inégalités en santé

English | Français GENÈVE, le 11 avril 2025 – Une initiative internationale inédite a rassemblé près de 5000 professionnels de santé pour partager leurs expériences face aux discriminations dans l’accès aux soins « Un enfant est mort parce que sa famille ne pouvait pas déposer 500 000 nairas [environ 300 francs suisses] avant le début des soins. Le père avait pourtant supplié qu’on s’occupe de l’enfant, proposant 100 000 nairas et promettant de vendre son bétail pour payer le reste. » Ce récit glaçant d’un professionnel de santé nigérian illustre la dure réalité des inégalités d’accès aux soins dont de nombreux témoignages ont été partagés lors d’un événement international consacré à l’équité en santé. Le 11 avril dernier, la Fondation Apprendre Genève a créé un espace de dialogue sans précédent, rassemblant près de 5 000 professionnels de la santé de 72 pays, dont 1 830 francophones.
