Development is adaptation: Bill Gates’s shift is actually about linking climate change and health

Reda SadkiGlobal health

Bill Gates’ latest public memo marks a significant shift in how the world’s most influential philanthropist frames the challenge of climate change. He sees a future in which responding to climate threats and promoting well-being become two sides of the same mission, declaring, “development is adaptation.” Gates argues that the principal metric for climate action should not be global temperature or near-term emission reductions alone, but measured improvement in the lives of the world’s most vulnerable populations. He argues that the focus of climate action should be on the “greatest possible impact for the most vulnerable people.” The suffering of poor communities must take priority, since, in his view, “climate change, disease, and poverty are all major problems. We should deal with them in proportion to the suffering they cause.” Climate change is about the health of the most vulnerable This position resonates with a core message that has emerged …

How the Lancet Countdown illuminates a new path to climate-resilient health systems

Reda SadkiGlobal health

The 2025 Lancet Countdown report has begun to acknowledge a critical, often-overlooked source of intelligence to build climate-resilient health systems: the health worker. By including testimonials from health workers alongside formal quantitative evidence, the Lancet cracks open a door, hinting at a world beyond globally standardized datasets. This is a necessary first step. However, the report’s framework for action remains a traditional, top-down model. It primarily frames the health workforce as passive recipients of knowledge—a group that must be “educated and trained” because they are “unprepared”, rather than build on existing evidence that points to health workers as leaders for climate-health resilience. The 2025 report confirms that climate change’s assault on human health has reached alarming new levels. Yet, within this sobering assessment lies a quiet but potentially pivotal shift. For the first time, the Countdown’s country profiles integrate direct testimonials from frontline health workers, explicitly acknowledging their “lived experiences as valuable …

Climate change and health: what the Lancet Countdown says about the value and significance of local knowledge and action

Reda SadkiGlobal health

Here is everything that the new Lancet Countdown says about the value and significance of indigenous and other forms of local knowledge, as well as their value for community-led action to respond to the impacts of climate change on health. Why does this matter? Read our article: How the Lancet Countdown illuminates a new path to climate-resilient health systems On the value of community-led action and the significance of local knowledge Defining community-led action by its local context and empowerment “Community-led actions are those spearheaded by self-organised individuals within a community, working together for a common goal. Rooted in local societal, cultural, and economic contexts, they can promote equity, empower local actors, and strengthen climate resilience.” Community-led action as a driver of meaningful progress “Individual, community-led, and civil society actions can drive meaningful progress with substantial health benefits.” Grassroots activities growing into formal organizations “These grassroots activities can grow into …

Colonization, climate change, and indigenous health from Algiers to Acre

Colonization, climate change, and indigenous health: from Algiers to Acre

Reda SadkiGlobal health

I sat in a conference hall in Rio Branco, Acre State, Brazil. My mind was in a sanatorium of Algiers, Algeria. This was where my mother was sent as a girl. They told her she got tuberculosis because she was an “indigène musulman”. In 1938, the year of my mother’s birth and after over a century of colonization, about 5 out of every 100 Algerian people got infected with tuberculosis each year. French colonial reports show that Algerians died from tuberculosis at much higher rates than French settlers. They claimed the disease was endemic due to the supposed inferiority of our people. And that she was going to die. Colonialism is a liar. She survived. And it took less than eight years for an independent Algeria, free of the scourge of colonialism, to eradicate the scourge of TB. Listening to the leaders at Brazil’s First National Seminar on Indigenous Health …

Gender in emergencies: a new peer learning programme from The Geneva Learning Foundation

Reda SadkiGlobal health, Leadership

This is a critical moment for work on gender in emergencies. Across the humanitarian sector, we are witnessing a coordinated backlash. Decades of progress are threatened by targeted funding cuts, the erasure of essential research and tools, and a political climate that seeks to silence our work. Many dedicated practitioners feel isolated and that their work is being devalued. This is not a time for silence. It is a time for solidarity and for finding resilient ways to sustain our practice. In this spirit, The Geneva Learning Foundation is pleased to announce the new Certificate peer learning programme for gender in emergencies. We offer this programme to build upon the decades of vital work by countless practitioners and activists, seeing our role as one of contribution to the collective effort of all who continue to champion gender equality in emergencies.

Text-based alternatives to expensive multimedia content

Against chocolate-covered broccoli: text-based alternatives to expensive multimedia content

Reda SadkiWriting

The great multimedia content deception Learning teams spend millions on dressing up content with multimedia. The premise is always the same: better graphics equal better learning. The evidence tells a different story. The focus on the presentation and transmission of content represents a fundamental misunderstanding of how learning actually works in our complex world. Multimedia content: the stakes have changed In a world confronting unprecedented challenges—from climate change to global health crises, from artificial intelligence to geopolitical instability—the stakes for learning have never been higher. We need citizens and professionals capable of critical thinking, navigating uncertainty, grappling with complex systems, and collaborating effectively with artificial intelligence as a co-worker. Yet much of our educational technology investment continues to chase the glittering promise of multimedia enhancement, as if adding more visual stimulation and interactive elements will somehow transform passive consumers into active knowledge creators. The traditional transmissive model—knowledge flowing one-way from …

Richard Mayer’s research on multimedia for learning actually proves text works better

Richard Mayer’s research on multimedia for learning actually proves text works better

Reda SadkiWriting

Educational technology professionals cite Richard Mayer’s 2008 study more than any other research on multimedia instruction. They are citing the wrong conclusion. Mayer did not prove multimedia enhances learning. He proved multimedia creates cognitive problems requiring ten different workarounds – and accidentally built the case for text-based instruction. What Richard Mayer actually found Through hundreds of controlled experiments, Richard Mayer identified ten principles for multimedia design. The pattern is striking: most principles involve removing elements from presentations. Five principles focus on reducing “extraneous processing” – cognitive waste that multimedia creates. Three principles manage “essential processing” when content is complex. Two principles foster deeper learning. The hidden message: multimedia instruction is so cognitively demanding that it requires ten specialized principles to avoid harming learning. Richard Mayer’s split attention revelation Mayer’s modality principle seems to endorse multimedia: learners perform better with graphics plus spoken text than graphics plus printed text. Educational technologists …

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 …

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, …
