Climate change and health: a new peer learning programme by and for health workers from the most climate-vulnerable countries

Reda SadkiGlobal health

GENEVA, Switzerland, 23 July 2025 (The Geneva Learning Foundation) –Today, The Geneva Learning Foundation (TGLF) announces the launch of “Learning to lead change on the frontline of climate change and health,” the inaugural course in a new certificate programme designed by and for professionals facing climate change impacts on health. Enrollment is now open. The course will launch on 11 August 2025. Two years ago today, nearly 5,000 health professionals from across the developing world gathered online for an unprecedented conversation. They shared something most climate scientists had never heard: detailed, firsthand accounts of how rising temperatures, extreme weather, and environmental changes were already devastating the health of their communities. The stories were urgent and specific. A nurse in Ghana described managing surges of malaria after unprecedented flooding. A community health worker in Bangladesh explained how cholera outbreaks followed every major storm. A pharmacist in Nigeria watched children suffer malnutrition …

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 …

What is the Impact Accelerator

What is The Geneva Learning Foundation’s Impact Accelerator?

Reda SadkiGlobal health

Imagine a social worker in Ukraine supporting children affected by the humanitarian crisis. Thousands of kilometers away, a radiation specialist in Japan is trying to find effective ways to communicate with local communities. In Nigeria, a health worker is tackling how to increase immunization coverage in their remote village. These professionals face very different challenges in very different places. Yet when they joined their first “Impact Accelerator”, something remarkable happened. They all found a way forward. They all made real progress. They all discovered they are not alone. The Impact Accelerator is a simple, practical method developed by The Geneva Learning Foundation that helps professionals turn intent into action, results, and outcomes. It has worked equally well in every country where it has been tried. It has helped people – whatever their knowledge domain or context – strengthen action and accelerate progress to improve health outcomes. Each time, in each …

PFA Accelerator: across Europe, practitioners learn from each other to strengthen support to children affected by the humanitarian crisis in Ukraine

Reda SadkiGlobal health

In the PFA Accelerator, practitioners supporting children are teaching each other what works. Every Friday, more than 240 education, social work, and health professionals across Ukraine and Europe file reports on the same question: What happened when you tried to help a child this week? Their answers – grounded in their daily work – are creating new insights into how Psychological First Aid (“PFA”) works in active conflict zones, displacement centers, and communities hosting Ukrainian families. These practitioners implement practical actions with children each week, then share what they learn with colleagues from all over Europe who face similar challenges. The tracking reveals stark patterns. More than half work with children showing anxiety, fear, and stress responses triggered by air raids, family separation, or displacement. Another 42% focus on children struggling to connect with others in unfamiliar places—Ukrainian teenagers isolated in Polish schools, families in Croatian refugee centers, children moved …

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 …

“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. …

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 …
